Off-Base Activities: "Killjoy Was Here!" 1956 US Air Force Animated Training Film Cartoon

Jeff Quitney

Airman Killjoy makes enemies, then Airman Archie tries to make friends, with the locals near USAF bases. "This film uses animation to instruct U.S. Air Force personnel on their responsibilities to communities surrounding their installations." US Air Force Training Film SFP-366 Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

   ...The establishment of military bases abroad enable a country to project power, e.g. to conduct expeditionary warfare, and thereby influence events abroad. Depending on their size and infrastructure, they can be used as staging areas or for logistical, communications and/or intelligence support. Many conflicts throughout modern history have resulted in overseas military bases being established in large numbers by world powers, and the existence of bases abroad has served countries having them in achieving political and military goals. The British Empire and other colonial powers established overseas military bases in many of their colonies during the First and Second World Wars, where useful, and actively sought rights to facilities where needed for strategic reasons. At one time, establishing coaling stations for naval ships was important. During the Cold War, the United States and the Soviet Union established military bases where they could within their respective spheres of influence, and actively sought influence where needed. More recently, the War on Terror has resulted in overseas military bases being established in the Middle East. Whilst the overall number of overseas military bases has fallen since 1945, France, Russia, the United Kingdom and the United States still possess a substantial number. Smaller numbers of overseas military bases are operated by India, Italy, Japan and Turkey. The United States is the largest operator of military bases abroad, with 38 "named bases" having active duty, national guard/reserve, and/or civilian personnel as of September 30, 2014. Its largest, in terms of personnel, was Ramstein AB, in Germany, with almost 9,200 personnel...

Crystals Go to War 1943 Reeves Sound Laboratories; Piezoelectric Quartz Crystals for Radio by Jeff Quitney more at http://ift.tt/12zFTqb The preparation and manufacture of quartz crystals for radio communications during World War II. Electronics playlist: http://ift.tt/1xRxQa4 Public domain film from the Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://ift.tt/gc84jZ http://ift.tt/PfESm2 Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings... Piezoelectricity Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors... http://ift.tt/Y8Ievl A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators, but other piezoelectric materials including polycrystalline ceramics are used in similar circuits. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to hundreds of megahertz. More than two billion crystals are manufactured annually. Most are used for consumer devices such as wristwatches, clocks, radios, computers, and cellphones. Quartz crystals are also found inside test and measurement equipment, such as counters, signal generators, and oscilloscopes... Piezoelectricity was discovered by Jacques and Pierre Curie in 1880. Paul Langevin first investigated quartz resonators for use in sonar during World War I. The first crystal-controlled oscillator, using a crystal of Rochelle salt, was built in 1917 and patented in 1918 by Alexander M. Nicholson at Bell Telephone Laboratories, although his priority was disputed by Walter Guyton Cady. Cady built the first quartz crystal oscillator in 1921. Other early innovators in quartz crystal oscillators include G. W. Pierce and Louis Essen. Quartz crystal oscillators were developed for high-stability frequency references during the 1920s and 1930s. Prior to crystals, radio stations controlled their frequency with tuned circuits, which could easily drift off frequency by 3-4 kHz. Since stations were assigned frequencies only 10 kHz apart, interference between adjacent stations due to frequency drift was common. In 1925 Westinghouse tried out a crystal oscillator in its flagship station KDKA, and by 1926 quartz crystals were used to control the frequency of many broadcasting stations and were popular with amateur radio operators. In 1928, Warren Marrison (of Bell Telephone Laboratories) developed the first quartz crystal clock... Using what are now considered primitive methods, about 100,000 crystal units were produced in the United States during 1939. Through World War II crystals were made from natural quartz crystal, virtually all from Brazil. Shortages of crystals during the war caused by the demand for accurate frequency control of military and naval radios and radars spurred postwar research into culturing synthetic quartz, and by 1950 a hydrothermal process for growing quartz crystals on a commercial scale was developed at Bell Laboratories. By the 1970s virtually all crystals used in electronics were synthetic... link:http://ift.tt/1EeeaSA

Riding 150mph with no helmet !

Riding 150mph with no helmet !

Do not attempt this! This was not a very smart thing to do but luckily, this guy didn’t get hurt.  This is what your face would look like while going 150 mph on a bike – without a helmet, so imagine what your face would look like if it hit the road at that speed! But if you thought 150 mph was bad, how about over 450 mph? Astonishingly, NASA did a scientific test in this field in the 1940s, going…
