Title: Improvements in or relating to the treatment of drying or semi-drying oils to produce substances for use in paint, enamel, lacquer or like protective coating compositions
IPC: C09D115/02
Filed: 1934-07-26
Abstract: A base for a paint, lacquer, enamel, or like is obtained by blowing a drying or semidrying oil at relatively low temperatures until not less than 60 per cent is a liquid insoluble in petroleum ether but soluble in ethyl ether, discontinuing the oxidation prior to substantial coagulation, and removing unoxidized and non-hardening constituents by a selective solvent, e.g. petroleum ether or naphtha. A resin and/or an acidic agent which is at most slightly volatile under the conditions and which retards coagulation are preferably present.  Specified oils treated are linseed, perilla, and soya. Resins mentioned are rosin, and ester gum, fused Congo, Congo ester, paracumaron, and phenol-formaldehyde resins.  Acidic agents include one or more of: maleic acid or anhydride, and malic, succinic, tartaric, salicylic, acetyl-salicylic, sulphanilic, anthranilic, benzoic, citric, picric, oxalic, lactic, and boric acids.  In an example: 1 lb. of ester gum resin is dissolved in 3 lb. of linseed oil, 0,5 per cent of maleic acid or anhydride added, preferably as a solution in acetone, and the mixture, with or without 0,04 per cent of cobalt linoleate or other drier, is blown at 80 DEG  C. for 25--30 hrs. until a sample just fails to dissolve completely in ethyl ether. After cooling the mixture is extracted 3 times with 3--5 vol. of petroleum ether, and freed from residual solvent by warming in vacuo. The product is conveniently put up as a 60--80 per cent solution in toluene, xylene, coal naphtha, or butyl acetate.  Typical coating-compositions are prepared by mixing 50 lb of base, 35 lb. of toluene, 14,5 lb. of naphtha, and 0,5 lb. of cobalt linoleate; or 35 lb. of base, 25 lb. of toluene, 23,5 lb. of naphtha, 8 lb. of lithopone, 8 lb. of titanium dioxide, and 0,5 lb. of cobalt linoleate.  They may be applied by spraying, dipping, or brushing, and the film dried and baked at 220--240 DEG  F., for 60--100 min. The base may also be compounded with nitro-cellulose or other cellulose esters.

Title: Driving unit comprising a thermal engine and a hydraulic power transmission
Inventor: PIGEROULET JEAN
IPC: B60W10/10
Filed: 1963-06-04
Abstract: 985,626. Hydraulic transmissions. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE. June 4, 1963,No. 22230/63. Headings F2C and F2D. An hydraulic transmission comprising a pump 2 and motors 4, 4a which are coupled to vehicle driving wheels 5, 5a has a by-pass 14 interconnecting the pressure and return lines 6, 7 under the control of a throttle valve 15 which is controlled in dependence upon input and output speed and the position of the accelerator pedal 12. The valve 15 is biased to its open position by a spring 29 and is closed by means of a piston 28 subject at 31 to pressure produced by an input driven pump 27, the output pressure of which is determined by a throttle valve 33. The valve 33 is connected by a spring 34 to the rod 16 of a piston 22 which is urged by a spring 17 in the direction opening the valve 33 and is urged in the closing direction by pressure at 21 supplied by a pump 18 driven by the motor 4a, the pressure of the pump being determined by a fixed restriction 20. The rod 16 has a pin- and-slot connection with a lever 23 which is pivoted at 24 and is contacted by the end 12a of the accelerator pedal. In operation with the vehicle stationary and the engine 1 idling, the pumps 2, 27 are idling, the valve 33 is open so that the throttle valve 15 is also open and the pressure and return lines 6, 7 are interconnected. On depressing the accelerator pedal the lever 23 tends to close the throttle 33, thus throttling the output of pump 27 the pressure of which rises and progressively closes the valve 15 to progressively increase the supply to the motors 4, 4a. Under normal running conditions the valve 15 is fully closed. Engine braking is provided since although the accelerator 12 would then be released, the pressure of the pump 18 would maintain the throttle valve 33 closed so that the throttle valve 15 would also be closed. As the vehicle slows down, if the accelerator pedal remains released, the delivery pressure of pump 18 decreases and valve 33 opens progressively, so that eventually the valve 15 opens and the engine rotates idly.

Abstract: 1,135,092. Arcing preventing in switches. ALLIS-CHALMERS MFG. CO. 19 May, 1966, No. 22251/66. Heading H1N. An arrangement for opening an A.C. circuit interrupter 10 at a current zero comprises means 15, 22, 23 for producing an input signal having the waveform of the current in the controlled circuit 11, a phase shifting circuit 31 . . . 33 to advance the signal waveform by an amount equal to the operating time of the interrupter and means to produce a tripping signal for the circuit interrupter at a current zero in the signal waveform. As shown, the output of the phase-shifting circuit is rectified at 37, is clipped by a circuit comprising a resistor 42 and a diode 40, is amplified by a transistor 47 and applied to a pulse producing circuit 53, 54. The resulting pulses are amplified by a transistor 55 and applied through a capacitor 65 to a transistor 66 which amplifies the negative pulses only when a transistor 70 is rendered conducting by a tripping signal applied to terminals 17, 18. These pulses are amplified by a transistor 78 to turn on a silicon-controlled rectifier 77 to trip the circuit interrupter. The input to the phase-shifting circuit is provided through a lowpass filter which removes high-frequency components from the input signal. As the phaseshifting circuit tends to eliminate low-frequency components and so could cause incorrect operation e.g. in the event of a D.C. offset, a lowfrequency compensator 90 . . . 99 restores the low-frequency components to the phase advanced signal.

A regulated power supply for a load such as a thermionic electron-emissive filament includes a sensor which produces a signal having an A. C. component, used to counteract variations in sensor sensitivity, and a D. C. component used to control the average power supplied to the filament. As shown, the heater 13 of an indirectly heated cathode is supplied from an A. C. source 6 by way of a thyristor 7 associated with a triggering circuit which includes a unijunction transistor 15 having its emitter electrode connected to the junction between capacitors 22 and 25. The signal on an electron collector 14 includes an A. C. component, due to heating and cooling of heater 13 as thyristor 7 switches on and off, and a D. C. component having a magnitude proportional to the average power supplied to the heater 13; this signal is applied, over a line 32, in opposition to the voltage from a bias source 26 connected to charge the capacitor 25. The rate of charge of capacitor 25 determines the point in the half cycle at which the thyristor 7 fires, and the Specification shows, with reference to waveform diagrams Figs. 2 to 6 (not shown), that the arrangement operates to provide compensation for variations in the sensitivity of the sensor 14 throughout a range of selected output power levels from the power supply.
