Abstract: 312,052. Du Pont de Nemours &. Co., E. I., (Assignees of Gauerke, C. G.). May 18, 1928, [Convention date]. Fats and fatty oils.-Beta-eleostearin, obtained as an insoluble solid by the action of light or ot chemical agents such as a solution of iodine on china wood oil, is rendered soluble, in certain solvents such as gasoline or naphtha by heating it up to about 500‹ F. The solution may be used as a varnish; or other varnishes containing fossil or synthetic resins with or without drying oils such as linseed oil, may be rendered fast drying by the addition of betaeleostearin. In examples (1) a glyptal resin modified by rosin glyceride is melted at 410‹ F. and beta-eleostearin added. The temperature is raised to 500‹ F. for 25 minutes and high boiling gasoline and cobalt linoleate drier in turpentine added. (2) "Amberol" resin, which is formed from resin and a phenol-aldehyde condensation product, is melted with betaeleostearin at 400‹ F. Litharge and manganese dioxide is added and the whole heated to 525‹ F. High boiling gasoline is added. (3) East India gum is dissolved in linseed oil at 580‹ F. and beta-eleostearin added.

Title: Improvements in circuit arrangements for gas discharge valves
IPC: H05B39/08
Filed: 1937-04-27
Abstract: 499,856. Valve relay circuits. REKLAMAKTIEBOLAGET EPOK. April 27, 1937, No. 12066. Void. Convention date, April 27, 1936. Addition to 459,291. [Class 40 (v)] In a photo-electric control circuit for a gasdischarge tube supplied from A.C. mains, the range of control grid voltages required to operate the tube when high anode voltages are applied is reduced by applying an auxiliary blocking voltage to the grid at the moment of high anode voltage, whereby the control voltage is only required to influence an effective anode voltage of the same order as the ignition voltage of the tube. The discharge tube 2 is controlled from a conventional photo-electric cell circuit 1, 5, 12 and operates a lamp 3 in its anode circuit which is supplied with alternating current from mains 8. The positive half-waves 13 applied to the anode of 2 are shown in Fig. 2, the negative half-waves being suppressed by a rectifier 9. An auxiliary voltage, the positive half-waves of which are shown at 14, is also applied to the anode over rectifier 11 with a phase displacement of about 120 from the mains supply 8. This may be effected by connecting the terminals 8, 10 to two phases of a three-phase source. A further negative voltage, in phase with the positive anode voltage half-waves 13 is injected into the control grid circuit over rectifier 7 (in this respect the circuit shown in Fig. 1 is inoperative); the resulting half-waves 17 are in opposition to 13 from the source 8. The steady negative control grid bias is represented at 18, Fig. 2, and while, this voltage is applied, the tube 2 is inoperative since the amplitude of wave 14 does not exceed that of 18 by the requisite striking voltage 15. When the bias 18 is removed by the activation of the cell 1, tube 2 will strike at point 15, but lamp 3 will not yet light as the current drawn by the voltage 14 is inadequate. At point 16, however, the wave 13 becomes effective and as the tube 2 is already ignited, the blocking voltage 17 has no effect on the discharge and the lamp 3 is illuminated. The auxiliary voltage 14 may be dispensed with by suitable phase displacement of the blocking voltage 17, as shown in Fig. 3. If 20 is the ignition voltage of tube 2, the tube cannot strike until the blocking bias 18 is removed. If this occurs at point 21, the tube strikes at point 20 and the blocking voltage 17 cannot then prevent the discharge.

Abstract: 570,436. Power transmission fluids. AUTOMOTIVE PRODUCTS CO., Ltd., and SMITH, W. P. July 26, 1943, Nos. 12163/43 and 9728/44. [Class 69 (ii)] The water tolerance of castor oil-glycol ether mixtures is increased, and the setting point or freezing point lowered, by treating castor oil or glyceryl tri-ricinoleate in the presence of a glycol monoether with an alkali hydroxide or alcoholate in excess of that required to neutralise the free acidity of the castor oil or ricinoleate. The reaction product may be washed with water to remove saponification products. The amounts of the ingredients are chosen or adjusted so that the final product contains approximately. 35 per cent oil and 65 per cent glycol ether. According to one example, drums of castor oil and of cellosolve are pumped alternately into a mixer, the last drum of cellosolve containing 35 ozs. of potash per gallon so that there is no appreciable contact of castor oil and potash 'solution until all is ready for mixing. After mixing, standing, and the addition of a further quantity of cellosolve, a mixture is obtained having a water tolerance of 21 per cent, viscosity 38 seconds Redwood at 38‹ C., and setting point - 60‹ C.
