	Envelope manufacture - Wikipedia, the free encyclopedia
		Prior to 1845 and the granting of a British patent to Edwin Hill and Warren De La Rue for the first envelope-making machine, hand-made envelopes were all that were available for commercial use as well as domestic.
		In this way the diamond-shaped wrappers acquired de facto official status and became readily available to the public notwithstanding the time taken to cut them out and the waste generated.
		Hill also installed his brother Edwin as The Controller of Stamps, and it was he with his partner De La Rue who patented the machine for mass-producing the diamond-shaped sheets in 1845.

		Besides inventing the first photoheliographic telescope, he took the first photograph of a solar eclipse 1860 and used it to prove that the prominences observed during an eclipse are of solar rather than lunar origin.
		De la Rue was born in Guernsey and joined his father in the printing business.
		De la Rue's interest in new technologies led him to apply the art of photography to astronomy.

		The first step in the solution of this problem was the invention by E. La Croix of the machine which has since been called the purifier, which removed the dirt and light impurities from the refuse middlings in the same manner that dust and chaff are removed from wheat by a fanning mill.

		Pioneer astrophysicist Angelo Secchi used 20 second exposures, and amateur astrophotographer Warren de la Rue used 60 second exposures to capture the prominences and inner corona.
		De la Rue used a solar telescope of his own design, made by the famous instrument maker Andrew Ross, with a 3 1/2 inch objective corrected for the blue- violet colors that early photographic processes were sensitive to.
		From 1858 to 1872, de la Rue used this photohelioscope at Kew Observatory in England to record the complete 11 year solar cycle in a series of almost 3000 collodion wet plates that clearly showed spots and faculae.

	The Treatment of Transparent Papers: A Review
		The first patent for chemically treated transparent paper was granted in 1846 in France and the process was commercially developed by the firm of Warren de la Rue in London (based on an 1857 patent by Gains).
		This transparent paper, variously referred to as parchment, Pergamyn, Papyrine, and similar names, was prepared by subjecting an already-formed sheet of paper to a brief bath in sulphuric acid, followed by several washes in water, a bath of dilute ammonia, and sometimes a coating or bath of glycerine or glucose.
		Hofenk de Graaff found impregnation not useful since the materials tested did not penetrate the dense surface of the tracing papers (this is useful in using a thermoplastic adhesive).

		He interpreted the images he had obtained as showing the limb of the moon sequentially occulting the flame-like protrusions, and thus convinced his fellow astronomers that the prominences were solar in origin rather than transient features in the terrestrial atmosphere or simply illusions brought on by the sharp contrast of dark and light.
		And, when Warren De La Rue published what he thought was a new method of observing the whole of a prominence without an eclipse by using only absorptive filtering, Huggins responded quickly, claiming he had already thought about that "three or four years since."
		De La Rue's 1860 eclipse photographs were highly regarded by his fellow astronomers as a significant achievement in both celestial photography and solar astronomy.

		De la Rue invented a photoheliographic telescope that permitted the sun's surface to be mapped photographically.
		With his colleagues Stewart and Loewy, they studied over 660 sun-spots, observing that they are depressions in the sun's atmosphere, and further attempting to show a connection between the frequency of sun-spot activity and planetary movement.

		Robert Hooke published a booklet in 1676 titled `Helioscopes', filled with an array of highly ingenious telescope designs, some of which were designed for solar observation and some of which were constructed and used.
		Warren De la Rue designed a photographic solar telescope, built by Andrew Ross in 1857 for the use of the Royal Society to establish a continuous record of solar activity.

		In 1820 another English inventor, Warren De la Rue, used a platinum filament inside a glass bulb, an idea Edison would later try but reject.
		The air inside the De la Rue bulb was pumped out, because inventors understood that if the filament was not in a vacuum, the oxygen in the air would cause a chemical reaction with the filament and destroy it.
		De la Rue’s platinum bulb worked, but platinum was far too expensive to use in commercial light bulbs.

		The formidable task of demonstrating its falsity, and of replacing it with a system corresponding to the true relations of the world, was undertaken by the active and exemplary ecclesiastic, Nicholas Copernicus, Canon of Frauenburg (1473-1543).
		The treatise in which it was accomplished, entitled "De Revolutione Orbium Coelestium", saw the light only when its author lay dying; but a dedication to Pope Paul III bespoke the protection of the Holy See for the new and philosophically subversive views which it propounded.
