Filed: 1964-05-14
Abstract: 1,087,241. Control of motors. JOSEPH LUCAS (INDUSTRIES) Ltd. March 11, 1965 [May 14, 1964], No. 20081/64. Heading H2J. [Also in Division A4] An electric windscreen wiper motor 13, 14 which drives a parking switch 15 is energized for intermittent wiping operation through a circuit including a capacitor 10, which is charged when the switch 15 is open through the motor armature 13 and a variable resistor 11 until it reaches a potential sufficient to energize transistors 9, 16 through which current passes to a relay coil 17. The latter then closes contacts 18 so that the motor armature 13 is energized through a second relay coil 19, and the capacitor 10 discharges to render the transistors switch 9, 16 non-conductive. If the parking switch 15 has not closed the motor remains energized through the contacts 18 and the coil 19, until the latter is short-circuited by the switch 15 to open contacts 18 and stop the motor. The cycle is then repeated.

Abstract: 647,445. Actuation of switches. SPEED DEVELOPMENT CO., Ltd., RUFFLE, W. H., and FULLER, R. C. July 30, 1948, No. 20289. [Class 38(v)] A switch sensitive to very small changes in fluid pressure but also capable of withstanding very high pressures, is so constructed that when used, for instance in an aircraft, to detect the stalling speed, the pressure at which the switch operates is not affected by the varied gravitational forces acting on the movable switch parts resulting from chan change of position of the switch. Pressure from a union 10 on a diaphragm 7 is transmitted by a disc 13 and stud 14 to a T-shaped lever 16 having a weighted end 16<SP>1</SP> and pivoted at 17, a contact 21 thereon normally engaging a contact 22 by pressure from a leaf spring 28. The spring 28 is secured to a tapered block 30 and its pressure is adjustable by the bevelled edge 33 of a nut 32 which is movable in an oblong frame 35 by means of a screw 34 rotatable in the frame 35 by inserting a key in a square bore 38. The frame 35 is pivoted at 36 between the sides of an inverted U-shaped port 37 to which is secured a further leaf spring 41 pressing on the frame 35 to urge the nut 32 against the spring 28, the spring 41 being much stronger than spring 28 and providing a substantially fixed abutment for the frame. The lever end 16<SP>1</SP> is so weighted that the weight of the stud 14 and disc 13 are counterbalanced and the pressure at which the diaphragm 7 separates the contacts 21, 22 is the same whether the switch is in the position shown, or inverted. The housing cap 1 may have a union 44 for admission of a static pressure as when employing the switch in conjunction with a pilot tube. According to the Provisional Specification the stud 14 carries a disc which completes the circuit by engagement with the base 5.

Abstract: 662,901. Mechanical wheeled toys. WELLS & CO., Ltd., A., and WELLS, A. W. J. July 4, 1950 [ Aug. 4, 1949], No. 20319/49. Class 132 (iii). A clockwork driven toy vehicle has mechanism for periodically interrupting the drive to the wheels and mechanism for periodically sounding a bell. In an omnibus embodiment (Fig. 3), the rear axle 18 rests on the rear end of a pivoted arm 20 which when engaged by a cam 25 causes the rear end of the chassis to lift and drive gears 23, 24 to disengage. Immediately before the drive interruption, a portion 34 on a second cam 26 causes pivoted striker 28, 31 to sound a bell 32. Just before the drive is resumed, two portions 35 on the same cam 26 cause the bell to ring twice in succession. A figure representing a conductor is moved to a projected position, before the vehicle stops, by means of a third cam acting on a link connected to the pivoted base of the figure. A spring causes the figure to return to its normal position when the cam has turned beyond its operative position. Alternatively, an eccentric type cam coacting with a circular strap may be used or the figure may be operated by the relative movement of the chassis and arm 20. In other forms, the vehicle may be a police car, fire engine or escape, or railway-type luggage truck, in which embodiments the bell may ring continuously when the vehicle is moving and stop when the vehicle is stationary. Alternatively, the bell may sound only when the vehicle is stationary. The mechanism which operates the figure in the omnibus embodiment may be used to raise a ladder when the toy is in the form of a fire escape.

Abstract: 1500392 Protecting the load of a DC-DC converter RCA CORPORATION 14 May 1975 [20 May 1974] 20325/75 Heading H2K [Also in Division G2] The output of a DC-DC converter powering driver transistors P 1 , N 1 , P 2 , N 2  (e.g. in a liquid crystal display) is interrupted by a controlled switch N R  if the difference between the input and output voltages of the converter falls below a predetermined level. The converter itself comprises a pulsed transistor Q 1  which repetitively interrupts the current through an inductor L, and a capacitor C which accumulates charge each time the inductor current is interrupted, thus building up on the capacitor a steady voltage greater than that of the source supplying the inductor. The switch N R  comprises a mosfet whose gate-source bias is equal to the voltage difference. The arrangement prevents the application of steady voltages across the crystal should the oscillator controlling the driver transistors and the converter fail.

Title: Improvements in the production of ethylene bis-thiuram monosulphide
Inventor: FORD IAN ALASTAIR MONCRIEFF
IPC: C07D285/36
Filed: 1955-07-20
Abstract: Ethylene bis-thiuram monosulphide is prepared by reacting an aqueous solution containing at least 1 per cent w/v. of a di-alkyl metal or di-ammonium salt of ethylene bis-dithiocarbamic acid with oxygen or air in the presence of an oxidation catalyst at a temperature not greater than 40 DEG  C., preferably 10-25 DEG  C., while the solution is vigorously agitated.  It is preferred to use di-sodium ethylene bis-dithiocarbamate as starting material but the di-potassium and di-ammonium salts may also be used.  The concentration of the solution may be as high as is obtainable, but concentrations of 5-30 per cent w/v. are preferred.  The preferred oxidation catalyst is manganese sulphate used in amounts of 5-10 gm. of sulphate per gm. mol. of starting material.  The agitation of the reaction mixture may be effected by blowing oxygen through the solution.  It is preferred to effect the reaction in a closed vessel into which oxygen is introduced under pressures of 2-50 p.s.i.g., the solution being pumped rapidly round a closed circuit including the reaction vessel and a cooler to remove the heat of reaction.  Circulation rates of up to 700 changes per hour are suitable.  A suitable form of such an apparatus is described.  Detailed examples are given.
