The development of the J79 turbojet began in 1952 as a more powerful follow-up to the General Electric J47 turbojet. The engine generated a maximum of 17,000 pounds of thrust (-15 version) with the afterburner operating.
The engine was used on the Convair B-58 Hustler, the first U.S. bomber capable of maintaining speeds in excess of Mach 2. The J79 also was used some fighters developed during the late 1950s. The two most famous examples are the McDonnell Douglas F-4 and Lockheed F-104, which were both capable of flying at Mach 2.

ELECTRIC PUMPING JACKS
By 1946, John Hawley and his engineers were looking for a method to pump oil wells without central powers and flowing heads. They experimented with various designs for electric pumping jacks and produced one that could pump two wells with a single rodline. Another prototype was an extremely heavy design that was never put into production, but its off center axle became the basis of all Hawley’s future designs.
NORTHERN ORDNANCE
Near the end of World War II, Minneapolis industrialist John B. Hawley, Jr. was convinced that oil shortages would occur by 1950. In 1943, his Northern Ordnance Company purchased oil lands in 18 states including Pennsylvania and made changes in the oil fields of Forest, Venango, and Warren Counties. Large compressors replaced smaller ones, steel spudding machines replaced portable wooden drilling rigs, and flowing heads and electric jacks replaced rodline units. Hawley sold out to Quaker State Refining Corporation in 1951. This display of machinery was done with assistance from Quaker State’s Titusville Office.
The AK is the Canadian General Electric version of the U.S. CK.
Used in the 1935, 1936 models. Filled with SO2 and operating at a higher pressure than the CA models. Externally, appearances are similar, but internally quite different.
Continuing my Quincy Smelter series: this is a detail of a wheel on a machine which was part of a steam engine. Notice the details on the spokes of the wheel -- totally unnecessary, but very striking.

I am not a Mormon so lets hope I get all this information correct.

The trumpet player is possibly Gold because he adorns the house of the Lord. It is more likely the angel statue is gold plated so that it won't tarnish and remain shiny for a very long time. Gold is an element that can withstand the effects of climate, weather, etc, so is used to preserve the statute. It also has significance to Mormon's in that the plates Moroni brought to Joseph Smith were made of the same material.
The trumpet player is a statue of Moroni, with a trumpet to his lips. He appears on almost all temples of The Church of Jesus Christ of Latter-day Saints. He has come to symbolize the proclaiming of the gospel of Jesus Christ in latter-days to every creature. He was one of the last authors of the Book of Mormon. More specifically, he was Mormon's son, whom the entire Book of Mormon was named after. Moroni wrote the last book in the Book of Moroni, called the book of Moroni. Moroni, being the last author of the book, buried them in the ground to preserve them for our day. He was a Nephite.
A constant goal of the Mormon Church is to "perfect the saints." Mormons understand the Biblical term "saint" to mean a member of Christ's Church, with today's members having the designation "latter-day saints," or members of Christ's Church living in these, the last days of the world.
Mormon temples are dedicated as places set apart from the world, thereby creating an atmosphere wherein the Holy Ghost can have a stronger effect on the human mind and heart. Members of the Mormon Church who maintain certain standards of conduct and have strong faith in Jesus Christ are permitted to enter temples.

Two things happened in the last week. 1. I saw a wonderful presentation on Abstract Photography. 2. I took a photo trip to San Francisco & Marin Co. with that presentation on my mind.
One stop on the trip was the Marin Headlands which is in the Golden Gate Recreation Area administered by the National Park Service. It is the Northern Shoreline of The Golden Gate entrance to SF Bay. A former military installation to protect the Golden Gate from invading ships there are several sites that were cannon batteries. These bunkers are above & below ground built to contain the big guns. Now this one serves as a graffiti gallery.
Available light photos taken within the tunnel.
