A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary byproduct, refrigeration creates waste heat that must be exhausted...
I received recently an unusual 35mm range-finder camera Graflex Graphic 35 made in the U.S.A. in 1955 (see below the details about Graflex company and the camera). After a complete inventory and blank mechanical/optical checking, I did a test film with a FOMAPAN 100. The light was metered using a Minolta Autometer III fitted with a 10° viewfinder for selective metering privileging this shadow areas.
The camera was equipped with an adapted French FOCA « Dyma » x3.5 36mm push-on filter plus the metal shade hood made for the FOCA Standard camera. To compensate the Dyma filter absorption the Autometer was set on 32 ISO instead of the nominal 100 ISO of the film. The Dyma FOCA filter is an original glass formula containing neodymium giving band-selective visible spectrum absorptions in the green and yellow so that proximate tonalities in these bands are better separated.
I did the all photos along the way to Lyon Saint-Jean, Lyon, France.

After the last view #37 exposed, the film was rewound to the taking cartridge and revealed in a Posso tank with 350 mL of Adox Adonal developer (identical to the original Agfa Rodinal in its formula of 1891) prepared at the dilution 1+50. The film was processed for 9min at 20°C.
The frames were then digitized using a Sony A7 camera (ILCE-7, 24MP) adapted to a macro Minolta Auto Bellow III with Minolta Bellow MD Macro lens 1:3.5 f=50mm and the dedicated slide duplicator Minolta. The light source was a LED panel (approx. 4x5') CineStill Cine-lite.
The RAW files obtained were inverted within the latest version of Adobe Lightroom Classic (version 15.4.1, June 2026) and edited to the final jpeg pictures without intermediate file. They are presented either as print files with frame or the full size JPEG's together with some documentary smartphone color pictures.

About the Graflex company and Graphic 35 camera:
Graflex (originally the Folmer & Schwing Manufacturing Company, founded in 1887 in New York) had long been renowned for its large- and medium-format press cameras (notably the Speed Graphic), which became the standard for photojournalism in the first half of the 20th century. After its acquisition by Kodak in 1905–1907, the works were moved to Rochester, New York. In 1926, following antitrust rulings, Graflex became independent again and continued production in Rochester until the early 1970s.
By the mid-1950s, large-format press cameras were losing ground to smaller, easier-to-use 35 mm cameras aimed at amateurs. Graflex responded by entering the 35 mm market. It had already marketed the Ciro 35 (derived from the earlier Cee-ay 35 of Candid Camera Corp., acquired via Ciro). In 1955 this design was thoroughly reworked into the Graphic 35.
Launch and Production
* Introduction: First shipments on 25 February 1955; press presentation on 8 March 1955 in New York.
* Manufacture: Body and final assembly in Rochester, N.Y. Lenses and shutters were imported from West Germany (Rodenstock or occasionally Enna “Graflar” 50 mm f/3.5 or f/2.8 lenses; Prontor-SVS leaf shutter, 1 s to 1/300 s + B, M/X sync, self-timer).
* Production period: Roughly August 1954 to July 1957 (sometimes listed as ending in 1958). Advertising continued into late 1960.
* Volume: Approximately 68,000 units (Graflex internal figures list 68,269 cameras distributed). Serial numbers began at 550,000 and later restarted at 1,100,000.
Introductory prices were about $77.50 (f/3.5) to $98–99.50 (f/2.8), making it one of the more affordable fully featured 35 mm rangefinders of its day.
Distinctive Features
* Push-button focusing on either side of the lens (“wing focusing”), invented by Graflex instrument maker Louis M. Traino, who received a $4,000 company award (roughly $35,000–40,000 in today’s money). A “Visi-Ready” distance scale was visible from above.
* Front-mounted, sideways-pull shutter-release lever.
* Spectramatic (later Universal Spectramatic) flash system, devised by engineering director Vernon Whitman: colour-coded bands that simplified aperture selection according to distance and guide number.
* Separate viewfinder and split-image rangefinder windows; film advance by knob (not coupled to shutter cocking, allowing intentional double exposures).
* Solid die-cast metal body with satin chrome finish and silver-grey leatherette covering (some later examples darker).
These features—especially the push-button focusing—were heavily promoted and helped the camera sell strongly in its first year.
After 1957–58 Graflex shifted to Japanese-made models (the Graphic/Century 35 series by Kowa, the Graphic Jet, etc.). The original Rochester-built Graphic 35 remains a characteristic mid-1950s American design: robust, unusually ergonomic in its controls, and still relatively affordable on the used market today.
It is one of the few non-Kodak 35 mm cameras actually made in Rochester and illustrates Graflex’s attempt to adapt to the postwar 35 mm amateur boom.
I did not find at now the optical formula of the lens. The lens takes 27mm screw-on filter and the external diameter is 32mm. With a little adaptation (rind made in a film canister cap...) one could fit the French FOCA filter push-on 36mm.
It seems that no lens cap was proposed for the Graphic 35. With a cap of Kodak 35mm canister, I made a plastic one to protect the front lens.
The range-finder is slightly off calibrated at infinite but it easy to correct the small shift to set the correct value on the distance scale that is only engraved in feet.
The well-understood benefit of sunlight is the production of vitamin D. When skin is exposed to sunlight, a series of chemical reactions begin that converts precursors of vitamin D to the active form of vitamin D. Vitamin D is needed for the intestinal absorption of calcium and the maintenance of calcium and phosphate levels necessary for healthy bone formation. It is also important for proper immune function, cell growth, and nerve and muscle function. Some foods naturally supply vitamin D, such as fish and liver. Other foods, such as milk and cereal, are typically fortified with vitamin D.
1. Sunlight and whole foods send breast cancer into remission. The American physician Dr. Zane Kime used sunbathing and nutrition to cure his patients. Even in terminal cases, Dr. Kime was able to completely reverse the metastasized cancer.
2. The sun's light kills bad bacteria. The German solders after WWI knew of the discoveries that had been made in 1903 by the Nobel Prize winner, Niels Finsen. They used sunlight to disinfect and heal wounds.
3. Sunlight has a beneficial effect on skin disorders, such as psoriasis, acne, eczema and fungal infections of the skin.
4. Sunlight lowers cholesterol. The sun converts high cholesterol in the blood into steroid hormones and the sex hormones we need for reproduction. In the absence of sunlight, the opposite happens; substances convert to cholesterol.
5. The sun's rays lower blood pressure. Even a single exposure significantly lowers blood pressure in individuals with high blood pressure. On the other hand, pharmaceutical drugs such as Statins have side effects, such as robbing the body of Coenzyme Q10. CoQ10 is essential for cellular and heart energy
6. Sunlight penetrates deep into the skin to cleanse the blood and blood vessels. Medical literature published in Europe showed that people with atherosclerosis (hardened arteries) improved with sun exposure.
7. Sunlight increases oxygen content in human blood. And, it also enhances the body's capacity to deliver oxygen to the tissues; very similar to the effects of exercise. The sun has a great effect on stamina, fitness and muscular development.
8. Sunlight builds the immune system. The white blood cells, which increase with sun exposure, are called lymphocytes, and these play a major role in defending the body against infections.
9. Regular sunlight exposure increases the growth and height of children, especially babies. Many cultures throughout history have recognized this fact. Studies have shown the amount of sun exposure in the first few months has an effect on how tall the person grows.
10. Sunlight can cure depression. The noon sunshine can deliver 100,000 lux. When we sit in offices for the best part of the day, out of the sun, under neon and artificial lights (150-600 lux), we are depriving ourselves of the illumination of nature. Sunlight deprivation can cause a condition called seasonal affective disorder (SAD), a form of depression. It is more common in winter months, but also common in people who work long hours in office buildings .Exposure to the sun should be done SLOWLY! If you are not used to the sun, then your skin will be more sensitive to it. Avoid sunburn by building up your tolerance SLOWLY. There are many known benefits of sunlight on mood and health, but regular sunlight exposure also can have long-lasting, positive effects on bone health, heart health, immunity and disease prevention. Sunlight often serves to encourage exercise, physical activity, travel and social interactions.

A variety of furniture styles and colours make this an inviting location for informal study. Easy access to power is provided from the ceiling mounted extension cables. Wireless access the the world wide web is also provided. Flexible screens for reconfiguration of space give students some privacy and help absorb sound.
A prototype of an acoustic absorption movable panel passed here in the early stages of development. I had to say that it worked very well, hope to try a more definitive and well finished piece in the future.
Barnard 150 (LDN1082), is a dark (absorption) nebula located in the constellation of Cepheus.
Due to its shape it’s also known as The Seahorse Nebula. Dark nebulae are clouds of dense interstellar material that obscures the light from objects behind it, such as background stars.

Zinc is present in many different foods. Foods with the highest zinc content include oysters, crab and beef. Phytates, which bind to zinc and limit its absorption into the body, are often present in plants — but plant-based foods, such as pumpkin seeds and oatmeal, can still be good sources of the mineral.
Bar graph shows zinc content of some common foods.

The Briar carbine is a firearm designed for close and medium-range combat, in settings such as urban locations.
It utilizes the 4.8mm caseless round, giving it a high rate of fire, coupled with the weapon's even weight distribution and recoil-absorption system, makes full-automatic shooting more accurate.
The setting Sun on June 30, 2014 as it set into a hazy or dusty sky and turned deep red/magenta, above the horizon clouds. I shot this through the 66mm William Optics apo refractor with the Canon 60Da camera at ISO 100. This is a composite of two exposures: longer for the sky and shorter for the Sun and details on the disk. A large sunspot group is on the eastern limb. This was shot without a filter -- atmospheric extinction dimmed the Sun enough naturally.

My shop time is my therapy. I love the creativity of building something of beauty (hopefully) with my hands, and the total absorption necessary to keep from screwing it up or hurting myself is healthy for my head. I've taken up building bigger things lately. This Shaker table is my first "official" piece of furniture. It is made of cherry that I milled and dimensioned myself from rough cut lumber. I even turned the knob for the drawer.
Normally, I would post several other photos of the details (the top, dovetails in the drawer, etc.) in the comments below, but with the new flickr interface, I don't think it will tell the story as well as it used to. If I posted them in my photostream, your home page would clogged with just my photos, right? What happens if a contact posts a hundred photos?
So... no, I don't care for the new flickr interface and I feel a need to voice my opinion. But I think upsetting new interface is serving to distract many of us from something even more important... more important to me, at least. The bigger deal to me is the community we've built. You people are important to me! I love getting to know you and know your stories through your photos and comments. I could get used to just about any interface if it was only about looking at photos, but this new design (and the encouraging everyone to ditch Pro accounts) make it much harder to make and see our comments, connections, and conversations around our photos.
I understand some things about business. Yahoo is not in business to make their customers happy, they are in business to make money. (Seems like the two would go hand in hand, but that isn't the corporate take on things these days.) Apparently they feel they will make more money through advertisers than through Pro accounts. Apparently they feel they will make more money by having a huge high-res photo database. I don't take their business decisions personally, and I would have been surprised had they asked me what direction they should take in redesigning their site for achieving their goal of making more money. I know my community means very little to the Yahoo corp.
Even though I "get" all that, I fear it will wreak havoc on my flickr community. I think flickr has been dying a slow death the last few years anyway... so many have left or disappeared or stopped posting as much. Clearly, something needed to be done to rejuvenate the site. Unfortunately, Yahoo is doing what they think is in their best interests, not ours.
It's too early to tell what will finally happen, but I am hanging on to my Pro account as long as I hang around here. I can't imagine looking at ads on top of the already atrocious new flicker look. And... since they so clearly want to do away with the Pro accounts, I may just keep re-upping simply because I'm an ornery, cantankerous, contrary old woman!! Long-winded, too!
Hope you like the table and love my little Angie.
Meanwhile, my energy has to go what I love. Like my Angie here, and the rest of my menagerie, and you, my friends. Love and big ol' hugs to y'all. And thanks to you, too.

ALE won the contract to receive and transport a 184te absorption tower from Richards Bay port to the Omnia Fertilizer plant in Sasolburg.
Transmission path ~3.5mm. The fluorescence is an average of a range of wavelengths between 354 and 407nm. The apparent 'noise' in the visible-nir spectrum is due to the interference fringing between different paths through this rough sample.
Title: Ernie strike-testing hollow cathode lamps, Varian Techtron, 679 Springvale Road, Mulgrave
Author / Creator: Sievers, Wolfgang, 1913-2007 photographer.
Date: 1974.
Varian Techtron was the result of a merger between the Australian company Techtron and the American firm Varian Associates in 1967. The Springvale Road site (then in Springvale North, but now in Mulgrave) was established by Techtron and is still in use, but now as Agilent Technologies (which acquired Varian in 2009). Techtron Appliances was established in 1938 and it and its successor companies have produced a variety of electronic and analytic equipment for industry and scientific research, notably including Atomic Absorption Spectrophotometers (AAS) to CSIRO specifications.

Gone are the days of CKPR (Cockermouth Keswick and Penrith Railway), before absorption into the LNWR and then LMS.
Originally a full station yard, 3 platforms, 4 tracks (one passing); quite a set up. Now a deserted platform used as part of the adjoining CKPR built railway hotel.
And now.... - just a lone platform part subsumed into the original CK&PR hotel, surrounded by a car park.

Infrared measurements of water absorption (1450nm, 1950nm and >2500nm) in the brownish edges and through the blue central regions of a sample of fluorite exhibiting disulphide fluorescence (see previous post). This suggests that the water resides principally in the discoloured regions near the edges of the crystals.
The actual pathlengths through the crystals were 33mm (brown) and 24mm (blue).

This is a comparison of the red fluorescence bands in the so-called 'disulphide' fluorite (blue line) and the yellow fluorite rod (red line, similar to the Hilton fluorite). The bands have an identical overall shape and wavelength position but the yellow fluorite has a considerably lower contrast rippled structure seen in the normalised emission (green line). The delta-k for both bands appears to be very similar, i.e., around 550 cm-1.
This is a figure used in my M.Sc. thesis which provides the spectral characteristics of the cyanine dye, CY3, in emission and absorption (excitation) along with the filter set (dichroic mirror in the filter cube, excitation filter, & emission filter) used in fluorescence microscopy experiments using our in situ spectroelectrochemical cell.

Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, green, blue and others. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.
