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.

The Gauribidanur Radio Observatory is a radio telescope observatory located at Gauribidanur , near Bengaluru. It is operated jointly by Raman Research Institute and the Indian Institute of Astrophysics . The observatory has been in operation since 1976. Location The Gauribidanur Observatory is located at Gauribidanur Latitude 13.60 N Longitude 77.44 E , 100 km north of Bengaluru. Science and Observation The Observatory has been used for studying various aspects of the Sun, galaxies and pulsars. A few observations with the array have been the first two dimensional images of radio emission from slowly varying discrete sources in the outer solar corona , an all sky survey of radio sources at 34.5 MHz in the declination range 30 S to 60 N, and a low frequency carbon recombination lines in astrophysical sources.Studies have been also been done of gaseous remnants of exploding stars and the apparently vacant space between members of a cluster of galaxies. Currently, the studies are targeted at pulsars .

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 250px 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.

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 , secretrary 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.

The Harquahala Mountains are the highest mountain range in southwestern Arizona , USA and are located southwest of the towns of Aguila, Arizona Aguila and Wenden, Arizona Wenden . 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 California Observatory Table Mountain , 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.

Signallers, aka Combat Signallers or signalmen or women, are commonly employed as radio or telephone operators, relaying messages for field commanders at the front line Army units, Ships or Aircraft , through a chain of command which includes Field headquarters and ultimately governments and non government organisations. Messages are transmitted and received via a communications infrastructure comprising fixed and mobile installations. Modern signallers are responsible for the battlefield voice and data communication and information technology infrastructure, using a variety of media. All types of wire line , satellite and ionispheric radio communication are employed. These include common radio systems such as HF VHF radio and UHF SHF radio operated in line of site for example . Cellular radio and telephone systems such as TETRA are becoming common for example. In the past, signalling skills have included the use of heliograph , Aldis lamp , Flag semaphore semaphore flags , Don R Dispatch Riders and even Homing pigeon carrier pigeon s. In addition to day to day soldiering, the signaller is required to be competent at a number of skill levels in the following topics Maintaining Power Supplies Batteries and Charging for example Radio sets storage and logistics installation and operation maintenance and repair at unit level.

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 . An important invention was the Rapid Rectilinear camera objective.
