Title: Improvements in or relating to films, filaments and other shaped articles made by hardening proteins coagulated from their solutions
IPC: C08L89/00
Filed: 1937-03-24
Abstract: Filaments, films, and other shaped articles made from casein or vegetable protein solutions by coagulation and hardening with formaldehyde or one of its near conversion products, are treated with hydrogen chloride or with a reactive chlorine compound hydrolysable to yield hydrogen chloride either in the form of a gas or vapour or in solution in a non-aqueous solvent indifferent to the protein and the chlorine compound, whereby the resistance to hot acids including acid dye baths or the water-repellent properties of the articles are improved.  Treatment may be effected at elevated temperature. Specified chlorine compounds are chlorides of organic or inorganic acids or of non-metallic elements, including phosgene, oxalyl chloride, furoyl chloride, acetyl chloride, adipyl chloride, thionyl chloride, sulphuryl chloride, sulphur monochloride, sulphur dichloride, phosphorus trichloride, phosphorus pentachloride, phosphorus oxychloride, and nitrosyl chloride.  Solvents which may be used include trichlorethylene, ligroin, toluene, benzene, olive oil, and turkey red oil.  The solvent is preferably a non-polar substance. In an example, filaments are obtained by extruding a solution of ground-nut protein in an aqueous solution of urea into a coagulating bath, and are hardened by treatment with formaldehyde. They are immersed in hank form in a solution of thionyl chloride in benzene, and after this treatment are washed and dried.  In other examples, artificial filaments of ground-nut protein are treated with solutions of thionyl chloride in trichlorethylene, sulphur monochloride in benzene, thionyl chloride in olive oil, phosphorus oxychloride in olive oil, acetyl chloride in trichlorethylene, phosphorus pentachloride, adipyl chloride, nitrosyl chloride, or sulphuryl chloride in benzene.  In other examples, hanks of ground-nut protein filaments are immersed in a solution of dry hydrogen chloride in benzene, or suspended in a heated chamber containing thionyl chloride vapour.  In other examples, hanks of casein filaments hardened with formaldehyde are subjected to treatment with oxalyl chloride or thionyl chloride vapour.  The handle and extensibility of the materials treated may be improved as well as their acid-resisting and water-repelling properties.  Specifications 467,173 and 467,704 are referred to.

IPC: H02M7/00
Filed: 1945-04-09
Abstract: 590,022. Protective cut-out arrangements. HEWITTIC ELECTRIC CO., Ltd., and MARTIN, L. J. April 9, 1945, No. 8744. [Class 38 (v)] In a supply system operating with mercuryarc rectifiers, a resistance 14 is connected across the main bus-bars 15, 16 during regeneration, by an electronic switch 13, the biassing voltage on the grid of which is obtained from an A.C. source through a transformer 30 and choke 27. The impedance of the latter to A.C. is normally negligible due to saturation by the load-current, so that a negative bias is supplied to the grid of tube 13, whereas, during the period of no-load preceding regeneration, the biassing volts are reduced so that the tube " fires." On regeneration, a reverse-current relay 20 closes contacts 19 which short-circuit the tube 13. The choke 27 may comprise an annular core around the bus-bar 15, or the D.C. winding may be wound on the core with the A.C. winding. The grid-volts may be rectified by an auxiliary rectifier, Fig. 2 (not shown), instead of in the mercury-arc rectifier shown.

Title: Input loading compensation for vacuum tube amplifiers
IPC: H03F1/50
Filed: 1951-04-19
Abstract: 678,693. Valve amplifying circuits. PHILCO CORPORATION. April 19, 1951 [April 20, 1950], No. 9189/51. Class 40 (vi). In a R.F. amplifier, such as an I.F. stage of a television receiver, variations of input resistance are minimized by connecting a resistor Rc between the grid and a source of potential which varies with the mutual conductance of the valve. The latter may be provided by a resistor Rk in the cathode lead of a valve 3, variations in the input capacitance C3 being minimized by suitable choice of resistor Rk. As the mutual conductance of the valve is increased, the effective potential across resistor Rc falls so that the resistance presented by Rc to the preceding tuned circuit rises to offset the fall in input resistance Rt of the valve 3. A.G.C. voltage is applied over filter Cf Rf and by-pass capacitor Cc to the grid resistor Rc.
