Image Heliograph wendelstein 2002 00a.jpg thumb A Campbell Stokes recorder Campbell Stokes sunshine recorder A sunshine recorder is a device that records the amount of sunlight sunshine at a given location. The results provide information about the weather and climate of a geographical area. This information is useful in meteorology , science , agriculture , tourism , and other fields. There are two basic types of sunshine recorders. One type uses the sun itself as a times scale for the sunshine readings. The other type uses some form of clock for the time scale. Image Sunshine recorders.jpg right thumb A Jordan sunshine recorder left . The other instrument is a Marvin sunshine recorder . Older recorders required a human observer to interpret the results recorded results might differ among observers. Modern sunshine recorders use electronics and computers for precise data that do not depend on a human interpreter. Newer recorders can also measure the global and diffuse radiation.

The Instructograph was a paper tape based machine used for the study of Morse code . The paper tape mechanism consisted of two reels which passed a paper tape across a reading device that actuated a set of contacts which changed state dependent on the presence or absence of hole punches in the tape. The contacts could operate an audio oscillator for the study of International Morse Code used by radio , or a sounder for the study of American Morse Code used by railroads , or a light bulb Aldis Lamp used by Navy ship to ship or by Heliograph . The Instructograph was in production from about 1920 through 1983. The latest version of the Instructograph was the model 500 which included a built in solid state oscillator. This model was available to be purchased as new through at least 1986.

An actinograph is an instrument for measuring or estimating the amount of light available, in terms of its ability to expose photographic film . That is, it measures the actinic or chemical intensity of light, as opposed to radiometry radiometric or photometry optics photometric amount of light. The earliest actinographs were 24 hour recording devices, using a rotating cylinder of photographic paper exposed through a wedged shaped slit to record a graph of actinic light during the period of a day hence the graph suffix in actinograph . Such devices were developed and described by Robert Hunt scientist Robert Hunt , secretary of the Royal Cornwall Polytechnic Society in 1845, as an improvement on T. B. Jordan s 1839 Heliograph . ref Klaus Hentschel, Mapping the Spectrum Techniques of Visual Representation in Research and Teaching , Oxford University Press, 2002, ISBN 0 19 850953 7. ref In 1888, Ferdinand Hurter and Vero Charles Driffield patented a device for estimating the actinic power of sunlight and for computing exposure times and apertures for cameras, based on the film speed plate speed , time of day, time of year, and latitude. These were slide rule s, not measuring instruments, and did not produce a graph, but Hurter and Driffield adopted the same name for it.

On leaving school at the age of sixteen he was apprenticed to an Osnabr ck optician, and in 1851 he came to London, where he obtained work with an optician, W Hewitt, who shortly afterwards, with his workmen, entered the employment of Andrew Ross, a lens and telescope manufacturer. Dallmeyer s position in this workshop appears to have been an unpleasant one, and led him to take, for a time, employment as French and German correspondent for a commercial firm. After a year he was, however, re engaged by Ross as scientific adviser, and was entrusted with the testing and finishing of the highest class of optical apparatus. This appointment led to his marriage with Ross s second daughter, Hannah, and to the inheritance, at Ross s death 1859 , of a third of his employer s large fortune and the telescope manufacturing portion of the business. Turning from astronomical work to the design and making of photographic lens design photographic lens es, he introduced improvements in both portrait and landscape lenses, in object glasses for the microscope and in condensers for the optical lantern .

The name originated from a local Native American people Aha qua hala , which meant water there is high up . The range is oriented from northeast to southwest and is approximately 32 km long and 20 km at its widest point. At the northeast are two prominent peaks, Eagle Eye Peak and Eagle Eye Mountain. One has a natural opening or bridge through it appearing as an eye high up, and is the namesake for the peaks and Aguila Spanish for eagle . The highest point, Harquahala Peak, rises to 1,732 meters. Socorro Peak 1,134 m is at the southwest end of the range. The very windy summit can be reached via a rough, 4 wheel drive road. This high point was used by the U.S. Army in the 1880s as a heliograph station. Then in 1920 a Smithsonian Astrophysical Observatory was constructed on this summit and operated for five years before being relocated to Table Mountain Observatory , near Wrightwood, California . Its purpose was to study variations in the solar output as a possible factor in climate prediction. Designated in 1990, the convert 22880 acre km2 0 sing on Harquahala Mountain Wilderness Area lies to the north and east of the summit at coord 33 49 40 N 113 17 52 W on the Maricopa County, Arizona Maricopa La Paz County, Arizona La Paz county line.

Fort White was a small military station built by the British Army under Field Marshal Sir George White British Army officer George Stuart White , V.C., Commander in Chief of Upper Burma during their third expeditions in the annexation of the Chin Hills in 1889. Its location was on the eastern leeward side of the Letha Range midway between Kale and Tiddim towns in what is now the Tiddim Township of Chin State , Burma Burma Myanmar . History of the name Though it was a mere military stockade, it was indicated as a well known spot on every old world map, as it was named after Field Marshal Sir George Stuart White who was one of the famous British peers. Plan It was garrisoned and a post and telegraph office was established there on the 13.1.1889 to be linked with their rearward, Kalemyo of Sagaing Division and other parts of the country down to Rangoon. During World War II During the second World War , it was reduced to ashes by air raids and shelling with heavy guns from the Allied Forces at mount Kennedy and yet it was not restored after the end of the war, since it had to be swerved off by the new Kale Tiddim motor car road from the old one intersecting it. It has been deserted ever since the British colonial government had left. There had been a heliograph station, too, on a horn of the Letha range near it to the west of the stockade at a distance of about four furlongs. It belonged to the Chin Hills Bn BFF of Falam to be communicated with other outstation such as, Kalemyo, No. 3 Stockade Natang , Dimlo Tiddim, Lungpi Falam and Haka. Later on, it was occupied by a detachment of the Allied Force until just before the Japanese army stormed the fort of White and it was razed to the ground in the war.
