Abstract: 185,397. International Wireless Appliances Corporation, (Assignees of Marrec, Y.). Aug. 29, 1921, [Convention date]. Undesired signals, eliminating or limiting; thermionic amplifiers and detectors.-In a method of eliminating parasites, received waves after rectification are passed through a series of highly damped amplifying circuits, of which five are shown to the left of the Figure, and then through tuned circuits, slightly damped, of which two are shown to the right. The highly damped circuits set up local alternating current through adventitious coupling, and this local current is tuned to a multiple or sub-multiple of the desired audio-frequency. A combination tone is thus set up, and the undamped circuits j are tuned to this. The heating of the filaments of the valves in the latter circuits is so adjusted that the valves act as current limiting devices for para. sites.

Title: Improvements in or relating to luminescent materials and methods of manufacturing the same
IPC: C09K11/59
Filed: 1944-09-25
Abstract: 620,835. Luminescent materials. THORN ELECTRICAL INDUSTRIES, Ltd., BALL, G. F., and STRANGE, J. W. Sept. 25, 1944, Nos. 18310/44 and 2140/45. [Class 39 (i)] A method of manufacturing a luminescent activated zinc silicate or substituted zinc silicate includes the step of firing a mixture of constituents containing a flux-like material not exceeding 0.5 per cent by weight of the final product, and potassium carbonate, potassium hydroxide, potassium oxide or other potassium compounds such as potassium bicarbonate which will form these compounds on heating, the amount of such potassium compound, e.g. 0.1 to 5 per cent of potassium carbonate, being sufficient to give between 0.06 and 2.8 per cent potassium by weight in potassium silicate in the final product, the total silica content of the mixture lying within the range, the upper limit of which does not substantially exceed the proportion of silica to the remaining constituents made up as follows : one molecule of silica for each two molecules of zinc oxide and of any substitute metal oxide or oxide-forming compound present and an additional amount of silica in the proportion of one molecule of silica to one molecule of each of the potassium compound and the activator, and the lower limit of which is 20 per cent below the said upper limit. In one example, 71.2 grams of zinc oxide, 28.6 grams of silica and .5 grams of potassium carbonate are mixed together and a standardised acid solution of manganese nitrate equivalent to 2 per cent of manganese in the final product and sufficient sodium chloride solution to give .001 per cent of sodium chloride in the final product are added, together with enough water to facilitate thorough mixing. The mixture is dried and heated to a dull red heat and then ground and heated to between 1050‹ and 1150‹ C., e.g. to 1100‹ C. for 12 hours. After a thorough grinding and mixing, the mixture is heated to between 1100‹ and 1200‹ C. for several hours, e.g. to 1180‹ C. for 90 hours. The product is a zinc potassium silicate activated by manganese. The proportion of potassium carbonate may be increased to such an extent as to yield 2 per cent of potassium silicate in the final product, thus enabling the final firing temperature to be reduced to 1050‹ C. In another example, the preparation of a zinc potassium beryllium silicate activated by manganese and using potassium chloride as a flux is described. Magnesium or calcium may be incorporated in the product as well as beryllium. According to the first Provisional Specification, caesium, lithium or sodium may replace potassium in the silicate. The Provisional Specifications also refer to weights of materials and firing temperatures differing slightly from those referred to in the Complete Specification.
