These wheels belong to a cryptoanalytic device called The Bombe used in Bletchley Park to crack the code of the Enigma cipher machine.
The Bombe has been developed by Alan Turing and Gordon Welchman based on a earlier Polish development called bomba kryptologiczna (this is where the name The Bombe comes from).
The Bombe utilizes the fact that the Enigma is an involutory device, i.e. the relations between letters in the plain text and the cipher text are reciprocal so that a letter A in the plaintext associated with B in the ciphertext is the same as B in the plaintext associated with A in the ciphertext. Using this fact together with the knowledge about the way the Enigma works, The Bombe is able to exclude wrong settings of the Enigma parameters by comparing the ciphertext with a piece of plaintext (called crib) which is assumed to be included in the message. Hence, after The Bombe has been set up with a menu derived from the ciphertext and the crib, the device performs an exhaustive search until the Enigma setup has been found which has been used for encrypting the cipher text.
The depicted device is a reconstruction of The Bombe, created in Bletchley Park within the Bombe Rebuild Project.

I believe this device is an optical instrument to attempt to locate the flash from Allied artillery batteries. The goal of protecting infantry from the devastating effect of artillery fire led to many technological advances in the Great War. Once recorded the flash points could be located through a number of different methods, and the battery in question could be fired upon. I believe they were called Mastfernrohr.
Looks like a Monarch doesn't it? But it's a Queen butterfly which also feeds on Milkweed and has a black-and-white spotted body.
The underside of the Queen is very similar to the that of the Monarch. Even the caterpillar is similar but has three pairs of thread-like tubercles (antennae) on its body. The Monarch has just two pairs, one pair at the head and the other at its tail.
Let's get scientific for a moment. Check this out!
"Because scent scales appear largely confined to the male sex, it seems reasonable to assume that male scent plays a role during courtship, and observations on the behavioral idiosyncracies of courtship in different species reveal that males actively use their scent-disseminating devices when courting a female. Tinbergen et al described how the male courtship culminates in a ‘bow’ during which he captures the female’s antennae between his forewings, whereby they are brought into direct physical contact with the male scent producing organ (Tinbergen et al., 1942). Likewise, in the queen butterfly, Danaus gilippus berenice, Brower et al. described how the male performs a courtship flight just above the female during which he everts his hairpencils and douses... Male monarchs first pursue females in the air, then proceed with aerial ‘hairpencilling’ before performing an aerial takedown just prior to copulation (Pliske,1974). jeb.biologists.org/cgi/reprint/210/6/964.pdf

This device was used for a few years for skid training. It raised or lowered the wheels of the ambulance and reduced traction at front, rear or side - or all at once! No longer restricted to a skid pan, the service could train on large spaces such as airfields.

In preparation for the FAFM photo for "Smoke", I had to make this make-shift 'smoke producing device' to create the smoke for the photo. As always, I have the correct 'supervision' so as to prevent accidents. The string produced a longer trail of smoke so I could take multiple photos and then choose the best one for the FAFM group. While not 'perfect' (and even a two-wick candle didn't suffice with sufficient smoke after extinguishing) this string would smolder for over a minute. The can is a clean tuna can, and the wire is 14-gauge copper wire.
After the fireworks were over, huge bright lights were turned on so the enormous crowd could find their way out of the park. We were on the water side of the hill, so it was still fairly dark where we were. However, the light of electronic devices lit the faces of my young Korean friends. The Gas Works are illuminated in the background.

We visited the Arecibo Observatory in 1977, just 14 years after observations of the ionosphere, pulsars, planets and exoplanets, quasars, and innumerable other objects and phenomena beyond the earth's atmosphere were initiated. We went again 10 years later, enabling me to get a couple of updated (and incidentally, better quality) images of the evolved technology.
Note that it is a radio-telescope, not an optical telescope, and collects data at wave lengths not detectable by light collectors. The giant perforated dish focuses incoming signals on the receiver suspended over the bowl.
Following severe damage by Hurricane Maria in 2017, and several subsequent earthquakes, on December 1 (of 2020, what else), the entire assembly collapsed. In spite of its record of thousands of major scientific discoveries over the decades by scientists collaborating around the world, it is uncertain whether it will be rebuilt. Its major funding source has been the U.S. agency, the National Science Foundation (NSF).
On that visit in 1977, we peeped under the dish, which is perforated and suspended several feet above the ground, we discovered lush ferns growing in the perfect conditions there.

"Those who see the Arecibo radio telescope for the first time are astounded by the enormousness of the reflecting surface, or radio mirror. The huge "dish" is 305 m (1000 feet) in diameter, 167 feet deep, and covers an area of about twenty acres. The surface is made of almost 40,000 perforated aluminum panels, each measuring about 3 feet by 6 feet, supported by a network of steel cables strung across the underlying karst sinkhole. It is a spherical (not parabolic) reflector .
Suspended 450 feet above the reflector is the 900 ton platform. Similar in design to a bridge, it hangs in midair on eighteen cables, which are strung from three reinforced concrete towers. One is 365 feet high, and the other two are 265 feet high. All three tops are at the same elevation. The combined volume of reinforced concrete in all three towers is 9,100 cubic yards. Each tower is back-guyed to ground anchors with seven 3.25 inch diameter steel bridge cables. Another system of three pairs of cables runs from each corner of the platform to large concrete blocks under the reflector. They are attached to giant jacks which allow adjustment of the height of each corner with millimeter precision.
Just below the triangular frame of the upper platform is a circular track on which the azimuth arm turns. The azimuth arm is a bow shaped structure 328 feet long. The curved part of the arm is another track, on which a carriage house on one side and the gregorian dome (installed in 1996) on the other side can be positioned anywhere up to twenty degrees from the vertical. Inside the gregorian dome two subreflectors (secondary and tertiary) focus radiation to a point in space where a set of horn antennae can be positioned to gather it. Hanging below the carriage house are various linear antennas each tuned to a narrow band of frequencies. The antennas point downward and are designed specially for the Arecibo spherical reflector. By aiming a feed antenna at a certain point on the reflector, radio emissions originating from a very small area of the sky in line with the feed antenna will be focused on the feed antenna.
Attached to the antennas are very sensitive and highly complex radio receivers. These devices operate immersed in a bath of liquid helium, to maintain a very low receiver temperature. At such cold temperatures the electron noise in the receivers is very small, and only the incoming radio signals, which are very weak, are amplified. The Arecibo system operates at frequencies from 50 megahertz (6 m wavelength) up to 10,000 megahertz (3 cm wavelength). A total of 26 electric motors control the platform. These motors drive the azimuth and the gregorian dome and carriage house to any position with millimeter precision. The tertiary reflector can be moved to improve focusing, receivers are moved into focus on a rotating floor inside the gregorian and the dynamical tie downs activate as needed to maintain platform position. The 1 MW planetary radar transmitter located in a special room inside the dome, directs radar waves to objects in our solar system. Analyzing the echoes provides information about surface properties and object dynamics.
This giant telescope has scrutinized our atmosphere from a few kilometers to a few thousand kilometers where it smoothly connects with interplanetary space. With its radar vision it studies the properties of planets, comets and asteroids. In our Galaxy it detects the faint pulses emitted hundreds of times per second from pulsars. And from the farthest reaches of the Universe quasars and galaxies emit radio waves which arrive at earth 100 million years later as signals so weak that they can only be detected by a giant eye like this one.
The giant size of the reflector is what makes the Arecibo Observatory so special to scientists. It is the largest curved focusing antenna on the planet, which means it is the world's most sensitive radio telescope. Other radio telescopes may require several hours observing a given radio source to collect enough energy for analysis whereas at Arecibo this may require just a few minutes of observation.
The huge "dish" is 305 m (1000 feet) in diameter, 167 feet deep, and covers an area of about twenty acres. The reflector’s surface is made of 38,778 perforated aluminum panels, each measuring about 3 feet by 6 feet, supported by a network of steel cables strung across the underlying karst sinkhole. It is a spherical (not parabolic) reflector. Suspended 450 feet above the reflector is the 900 ton platform. There are three towers supporting towers supporting the platform. One is 365 feet high, and the other two are 265 feet high. All three tops are at the same elevation. Each tower is back-guyed to ground anchors with seven 3.25 inch diameter steel bridge cables. Just below the triangular frame of the upper platform is a circular track on which the azimuth arm turns. The azimuth arm is a bow shaped structure 328 feet long and can be positioned anywhere up to twenty degrees from the vertical.

"Fallen Giant
Summary
The story of the collapse of the Arecibo telescope is now well known. On 10 August 2020, a steel cable supporting a 900-ton instrument platform high above the dish broke at one end and fell, slicing into the dish. A second support cable snapped on 6 November and the National Science Foundation said attempting repairs was too dangerous: Arecibo would be dismantled. On 1 December, fate took control as more cables snapped and the platform came crashing down into the dish. The loss dismayed scientists worldwide. Although 57 years old, Arecibo was still a scientific trailblazer. The public, familiar with the majestic dish from films such as Contact and GoldenEye, also felt the loss. And it was a bitter blow to the people of Puerto Rico, who embraced hosting the technological marvel. Some experts think manufacturing flaws or poor maintenance doomed the suspension cables. Others blame dwindling funding levels. But astronomers are looking to the future. Last month, researchers announced plans for a new $400 million telescope on the same site."

"This lively corner structure is enriched with a wide assortment of Queen Anne devices, including a three tiered corner tower with both hexagonal and round sections, angled bays, multiple gables with window-lit gable-ends, assertive cornice lines, a dormer and an oriel, not to mention garlands, fishscale shingles, dentils, and assorted brackets. Much of the interior also remains, having been restored and refitted when the building became the Queen Anne Hotel in 1980. The original central hallway survives, with its oak paneling, as does the squared spiral staircase beneath a large stained glass skylight. The most important elements that have been lost include the bell-shaped roof to the corner tower and the grand exterior granite staircase to a massively arched open vestibule before the main door. Miss Mary Lake's School for Young Ladies was a fashionable , non-sectarian seminary that grew from Miss Zeiska's Young Ladies Seminary in South Park in the 1860s. Enrollment was probably about 120 students, ranging in age from "infants" through high school. There was room for 65-70 boarders in the building. James G. Fair, of Comstock Lode fame, and the father of girls, was the major benefactor of the school having the school built in 1889, sparing no expense, for $45,000.00. The school survived only seven years at this site. The building was then leased to the Cosmos Club which counted such local moghuls (sic) as James Flood and Governor George Pardee among its members. From 1909 to 1926, it was used as a boarding house. In 1926 the building became the Girl's Friendly Society Lodge, a home for young working women. From 1950 to 1975 it was used as a guest house called The Lodge. Henry Schulze practiced from 1887 through 1908."
