Abstract: 480,355. Supply systems for cathoderay tubes ; converting.BLUMLEIN, A. D., and SPENCER. R. E. July 18, 1936, No. 19944. [Classes 38 (ii) and 38 (iv)] Voltage accommodation.-D.C. supply to the first and second amodes of a cathoderay tube is taken from across a potentiometer resistance R1, R2, the first anode being supplied from a tapping on the potentiometer R2 and the second anode from across the supply through a resistance R3 and the valves of the resistances R1, R2 and R3 being so co-related with the anode current-grid voltage characteristics of the separate anode circuits that disproportionate variations in the anode voltages arising from differences in the characteristics are substantially compensated. The ratio between the respective anode voltages is thereby kept constant and the focusing ratio maintained constant. Condensers C1 and C2 are connected across the electrode supplies to absorb rapid fluctuations and may effect partial smoothing of the H.T. supply. The condensers also serve to maintain the focusing ratio and to prevent changes in scanning amplitude with changes in picture-brightness in a television receiver. The resistances R2, R3 may be adjustable and the respective circuits of the condensers Cl, C2 have equal time constants. Formulae and an example are given in the Specification. Specifications 407,857; and 410,478, [Group XL], are referred to.

Title: Improvements in or relating to manufacture of methyl and ethyl lead compounds
IPC: C07F7/24
Filed: 1938-07-09
Abstract: 516,875. Organic lead compounds. ETHYL GASOLINE CORPORATION. July 9, 1938, No. 20396. Convention date, Feb. 16, 1938. [Class 2 (iii)] A mixture of methyl and ethyl lead compounds which includes methyl-ethyl lead compounds is prepared by reacting ethyl chloride and a methyl halide with a sodium-lead alloy having an approximate composition NaPb, in the presence of a catalyst comprising boron trifluoride, dimethyl beryllium or a catalyst of the aluminium type. The compounds included within the latter category comprise aluminium, aluminium chloride, aluminium with an activator selected from the group of iodine, zinc, tin, magnesium, mercuric chloride, mercuric bromide and rhenium chloride, aluminium alloys which show a tendency to react with an alkyl halide, such normal butyl chloride when boiled therewith under reflux, the products of this reaction either alone or in the presence of a sensitizer comprising a compound from the group, iodine, ferric chloride or stannic bromide, dimethyl aluminium chloride, methyl aluminium dichloride, aluminium ethoxide, ethyl aluminium diiodide, dimethyl aluminium bromide, trimethyl aluminium and mixtures of these. If desired two catalysts may be used, so selected that one acts more rapidly than the other in initiating the reaction. Several examples of suitable aluminium alloys are included. The proportions of the two halides employed are varied according to the composition of the desired end products. The reaction may take place in the liquid or vapour phase and is preferably conducted in an autoclave. An inert solvent such as hexane, benzene, decahydronaphthalene or kerosene may be employed. A portion or all of the alkyl halides and catalysts may be added, either intermediately or continuously during the progress of the reaction; and in this way the progress of the reaction may be controlled. An additional method of control is to vary the particle size of the catalyst. The products of the invention may be separated from unwanted products prepared simultaneously in the reaction by tractional distillation. The accumulation of the above undesired products may be avoided by combining the above manufacturing process with the redistribution process of Specification 516,874. In an example a mixture of tetramethyl lead, trimalkylethyl lead; dimethyldiethyl lead and tetraethyl lead is prepared by the interaction of 1,380 parts of NaPb, 160 parts methyl chloride, 416 parts of ethyl chloride, and a catalyst consisting of 2 parts of aluminium alloy containing copper, zinc, iron, and silicon and 4 parts of anhydrous aluminium chloride, in an autoclave at 100‹C.
