Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B7/00
Filed: 1937-03-11
Abstract: 491,730. Hydraulic transmission of power; reciprocating pumps ; screw propellers. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. March 11, 1937, Nos. 7197 and 17978. [Class 69 (ii)] [Also in Groups XXVIII and XXXIII] A liquid-pressure remotecontrol system for adjusting and equalizing speeds of a number of engines or variable pitch propellers, comprises a transmitter A, a number of slave units B, B' and a control device 11 having a number of positions in one of which the transmitter actuates all of the slave units in unison and in another it actuates one slave unit individually. The control device also operates a switch 20 controlling lamps 21, 22 for indicating which of the slave units is or are operative. The switch also controls an electrical indicator C which is placed in circuit with one or other of resistances 18, 18<1> on the operative slave unit to indicate its setting, the indicator being connected to one selected slave unit when all units are operative. As shown for two slave units the transmitter comprises two pumps 39 each operated by a cam 35 and follower 42 from a hand wheel 10 through a clutch 36 or 36a, Fig. 2, having clearance between the teeth. Initial movement of the hand wheel takes up this clearance and also rotates a lever 31 through friction discs 27 to move valves 34, 34a out of mid position to which they are returned by a spring when the hand wheel is released. The valves 34 in mid position connect both pipes 57, 58, leading to opposite ends of a slave unit, to reservoir 23 and in end positions connect one pipe to reservoir and the other to the pump. Continued rotation of the hand lever after movement of the valves 34 operates the pumps to actuate one or other or both of the slave units. Reverse rotation of the hand lever first reverses valves 34 and then operates the pumps for moving the slave units in the opposite direction. When both slaves are to operate, a lever 11 is maintained in central poistion. Movement of this lever in either direction rotates a cam 75 for each pump, each cam being operative to lift the suction valves 46, 47 of its pump for one position of the lever thereby preventing operation of one pump and its slave unit. Alternatively the pumps may be cam and tappet operated and controlled by movement of the tappet. The slave unit pistons are locked in any adjusted position by balls 111, 112, Fig. 9, pressed by a spring 115 between the cylinder wall and conical surfaces on the piston. Pressure liquid supplied to one end of the cylinder overcomes the spring and permits movement of the piston. A single pump supplying all slave units through a control valve may be used and each slave may be single acting with a return spring. The slaves may be used to adjust speed governors controlling the incidence of variable pitch propellers, or to adjust engine throttles in aircraft, or ships, or for controlling fuel injection in compression ignition engines. Specifications 443,871 and 468,976 are referred to in the first Provisional Specification.

Title: Improved apparatus for balancing rotating parts
IPC: G01M1/22
Filed: 1950-03-28
Abstract: 671,093. Balancing rotating bodies. GENERAL MOTORS CORPORATION. March 28, 1950. [April 9, 1949] No. 7673/50. Class 40 (i). [Also in Groups XVIII, XIX, XXII and XXXV] A rotor to be balanced is associated with a pick-up generating signals proportional to the vibration of the support, these signals being fed through a potentiometer to an indicator which also receives a synchronising signal once per rotor revolution so as to provide information for determining where the rotor requires to have material removed to be balanced. As shown, a balance wheel 2 is mounted for rotation on a flexible support 8, oscillations of the support 8 producing electric oscillations in a condenser pick-up 12 for amplification at 34 and application over potentiometer 38 to the cathode ray oscillograph 29. A driven shaft 16 carries a calibrated disc 14 bearing three magnets 18 to form a clutch for rotating the wheel 2. A small magnet 22 on disc 14 at the zero calibration provides a synchronising signal in coil 24 for controlling the time base of the oscillograph 29. In operation, the magnitude of the trace on the oscillograph is adjusted to lie between defined limits by variation of potentiometer contact 41, cam 50 being correspondingly positioned. Shaft 16 is then stopped, and manually adjusted so that the calibration on disc 14 corresponding to the position of the maximum of the oscillograph trace is opposite the index 20. The wheel 2 is then lifted from the support 8, and without variation of its.orientation, is placed on cam 50. Cam 50 and the wheel 2 is then transferred to the platform 78, Fig. 3, of a drilling machine, its position under the drill 86 being determined by the loop 58 on cam carrier 50 embracing peg 82 ; a stop 74 is adapted to bear on the cam 50 and thus determine the depth to which metal is removed by the drill to balance the wheel.

A storage device comprises an insulating card on which are printed a plurality of row and column conductors, printed diodes interconnecting row and column conductors at intersections thereof. In one arrangement, Fig. 5, row conductors R1, R2 are associated with pairs of column conductors such as C1, C1<SP>1</SP> and are initially connected to each conductor C1, C1<SP>1</SP> through a diode 25, 26. A " 1 " or " 0 " is stored by punching a hole 34 or 36 to isolate each row conductor from one or the other of conductors C1, C1<SP>1</SP>. In another arrangement, each row conductor R1, R2 is initially connected to each conductor C1, C1<SP>1</SP> by individual diodes, and information is stored by punching out one of the diodes. By connecting the row conductors to a common bus 14, Fig. 7, through printed resistors b1-b6 and extending this bus and the column conductors to the other side of the card, a plurality of cards may be connected in series in a stack as shown in Fig. 4. Fig. 7 shows a tag-addressed store. Switches S1, S2 associated with tag bits are left open, and switches S3-S5 associated with data bits connect column conductors C3, C3<SP>1</SP>-C5, C5<SP>1</SP> to a positive bus through resistors r3, r3<SP>1</SP>-r5, r5<SP>1</SP>. A desired tag is entered by applying appropriate voltage polarities to terminals T1, T1<SP>1</SP>, T2, T2<SP>1</SP>, whereupon one row conductor, e.g. R3, becomes negative and the data bits associated with that conductor appear at terminals T3, T3<SP>1</SP>-T5, T5<SP>1</SP>. If more than one conductor becomes negative upon entering the tag, e.g. R1, R4, a switching arrangement is required to read out each set of data bits in turn. If desired, groups of more than two column conductors may be provided each row conductor being connected to one column conductor in each group through a diode, and a tag or data bit being represented by a distinctive marking on one of the column conductors in a group. The storage cards may also be read by a conventional punched-card machine sensing the perforations 34, 36.

Abstract: 453,532. Coated fabrics. DEUTSCHE KUNSTLEDER - WERKE WOLFANG GES., Wolfgang, Hanau, and SIMONS, P., 41, Lrajanstrasse, Cologne, both in Germany. March 14, 1935, No. 7975. [Class 140] A process for producing artificial leather having an obliquely threaded fabric base, consists in first applying a thin preliminary coating of artificial leather composition by lightly surface coating, then cutting the fabric obliquely and further treating, e.g. by one or more additional coatings of composition, calendering, graining, &c., as required. The composition may be a cellulose derivative with softening agents, e.g. castor oil, tri-phenyl phosphate, with pigments and a solvent, or a rubber composition or rubber latex which may be pigmented. The composition may be applied to a straight-threaded fabric which is then sewn to form a tube with the coating inside. After the edges have been trimmed it is cut along a helical line, calendered, given a final coating of composition and then grained. Alternatively, a tube of straight - threaded fabric may be folded flat and the preliminary coating applied to the outside thereof, the fabric being further treated, as above. The fabric base may be stretched, e.g. so that the threads become inclined at about 70‹ to one another, before use the surface covering composition has been applied.
