IPC: D06F33/36
Filed: 1957-11-01
Abstract: 833,922. Washing machines. GENERAL MOTORS (FRANCE). Oct. 13, 1958 [Nov. 1, 1957], No. 34139/57. Class 138 (2). A washing machine includes a rotatable clothes tub, a stationary water container to receive water overflow therefrom, a water inlet to the tub and a pump arranged to draw water from the water container and deliver it through a heater to the tub until the desired temperature is reached. The machine is started by the actuation of timer control knob 20 to close switch 120 and complete the circuit through electromagnet 109 which opens a valve to allow fresh water to enter tub 47 through nozzle 106. When water overflows through apertures 49 it leaves container 23 through aperture 30 and passes over pressure-sensitive switch 33, flows through the pump and heater and is returned to the tub via nozzle 100. When the water level in tube 32 rises sufficiently to actuate switch 33, movable contact 111 disengages from contact 110 and engages contact 112, thus breaking off the fresh water supply and energizing temperature sensitive switch 114, the temperature-sensitive element of which is located near the heater outlet, contact 113 engaging contact 115 when the water is cold. 119 is a conventional bimetallic safety device for electromagnet 117 which turns on gas valve 107 of the heater, the pump operating continuously to circulate water from the container, through the heater and back into the tub. When the water reaches the desired temperature, contact 113 of switch 114 engages contact 116, thus discontinuing the heating and setting in motion timer motor 118 which controls conventional timer mechanism for an automatic sequence of operations. Electric instead of gas heating may be used and the machine may be manually instead of automatically controlled. Specification 770,815 is referred to.

[Class 80 (iv)] Rotation of a shaft A, mounted on the gearing frame end C of a textile spinning and twisting machine in one direction or the other, locks or unlocks the draft wheel covers and the twist wheel panel, and at the same time'actuates the belt-shift-fork, or an electric switch. With the parts in the positions shown the belt (not shown) is on the loose pulley O, and a stud n on the fork N opposite a vertical part m<3> of a slot m<1> in a pivoted bracket M. If the bracket be raised the stud passes into the slot m<3> and locks the belt on the pulley O. Also a rod L is raised and turns the shaft A thereby moving a horizontal bar d<1> clear of the draft wheel covers E<1> and withdrawing a projection G<2> from slots in the panel J and the top panel c<2> of the frame end. The covers can now be lifted. If this is done the belt cannot be moved to the fast pulley until the covers are lowered again. The bracket M is then released and falls until the stud n faces the slot m<1> so that the fork can be moved to transfer the belt to the fast pulley P. The rod L also falls and with it the bar d<1> to span the covers E<1>. The projection G<2> re-engages its slots in the panels. In the case of electric drive, Fig. 5, the spindle V of an interlocking switch W carries an arm U connected to a link T hinged to a bracket S on the bar d<1>. To open the covers J, E, the bar d<1> and arm G<1> are moved to the position shown, Fig. 5, in which movement the switch W is opened to stop the motor. To re-start, all the covers must be closed. The bar d<1> and shaft R can then be moved by hand to push the projection G<2> through its slots by means of links F, B, and close the switch W to start the motor.

Abstract: 1395954 Power-assisted steering GEMMER FRANCE 26 July 1972 [28 July 1971 17 March 1972 19 July 1972] 35001/72 Heading B7H [Also in Division G1] A follow-up switch incorporated in the steering column of a vehicle to allow an electric motor to assist the steering includes a torsion member measuring the applied torque and having an adjustable elasticity to preset the torque at which the servo motor is energized. As shown (Figs. 1, 2), the steering column comprises a first section 1 attached to the steering wheel 4 and a second section 2 attached to the steering members, coupled by a torsion bar 3. Each section 1, 2 carries one part 5, 6 respectively of a follow-up switch. When the torque applied to the steering wheel 4 exceeds a preset value the angular displacement between sections 1, 2 allows the wings of part 5 to contact the sides of the slots in part 6, thereby switching on a servomotor 18. The torque may be measured by a circular resistance potentiometer 8 fixed to part 6 with its slides driven through gears 12, 13 by section 1 of the steering column, to produce a torque signal which is fed to motor 18, with the follow-up switch 5, 6 determining the direction of rotation. The torque signal may be modified by a speed signal derived from a potentiometer 20 (Fig. 5) whose slider is coupled to the pointer of a speedometer 19, and is wound in three sections A, B, C giving different relationships for high, normal and low speeds. At high speeds the signal may be of opposite polarity to reduce the power assistance supplied by motor 18. The motor may be coupled to the steering mechanism through an electromagnetic clutch which is energized in parallel with the motor. The torsion bar 3 may be replaced by alternative spring arrangements whose elasticity is adjustable.

Title: Improvements relating to super-regenerative radio receivers of the type associated with transmitting means
IPC: G01S13/76
Filed: 1945-12-28
Abstract: 605,523. Radio signalling. FERRANTI, Ltd., WOOD, H., DAVIES, R..H., and WHITEHEAD, J. R. Dec. 28, 1945, No. 35039. [Class 40 (v)] A responder for use with a pulsed interrogating signal comprises separate transmitting and super-regenerative receiving valves having a common oscillatory circuit connected between their control-grids and anodes, but with independent cathode circuits, with means for maintaining the sensitivity of the receiving valve substantially constant during operation. Interrogating pulses from aerial coil 5 are amplified super-regeneratively by valve combination 1, 7, rectified by diode 22 and amplified by pentode 27 for application to the pulse lengthening circuit 39, 41, associated with cathode follower 34. The lengthened positive pulse from network 39, 41 raises the cut-off bias on transmitting valve 15, causing it to oscillate violently and re-transmit a response signal. Use of separate cathode circuits enables the time constant for the receiving valve to be reduced to allow rapid recovery without impairing pulse lengthening at the transmitting valve, while the common tuned circuit combines with blocking capacitors 13, 13<1> to protect the transmitting valve from quench frequency oscillations. During intervals between reception, amplification of random fluctuations in valve stage 1 produce periods of oscillation which are also rectified by diode 22, and the quench frequency component is rejected in tuned circuit 60, 61. The random voltage component is rectified by diode 65 and smoothed by filter 74, 70, 76 for application as a negative bias on receiving valve 1. A change in sensitivity during sweeping of capacitor 6a results in a change in noise level which gives rise to a correcting bias on the receiver valve 1. Specification 591,965 is referred to.

Title: Improvements in and relating to artificial limbs
IPC: A61F2/68
Filed: 1960-10-13
Abstract: 1,007,431. Artificial legs. J. L. COOK. Jan. 15, 1962 [Oct. 13, 1960], No. 35166/60. Heading A5R. An artificial leg has upper and lower leg portions pivotally interconnected at the knee joint and means associated with the knee joint to straighten the leg after a predetermined bent position has been reached, the means being rendered inoperative by pivotal movement of the foot relative to the lower leg portion. The knee joint comprises a pivot 12, the pins 37 of which are splined to the shin portion 11 and to a set of parallel interconnected arms 30 for pivotal movement therewith. A second set of arms 31 is pivotal on the pivot 12 and normally moves with the set of arms 30, the two arms 31 having spring-urged detents 49 which engage ratchets 50 on the two outer arms 30. A third set of arms 28 is pivotal about the pivot 12, the arms being interconnected by a transverse rod 40, which is interconnected by a spring 41 with a transverse rod 36 interconnecting the arms 30. Chains 27 extend from the arms 28 over wheels 51, carried by the arms 31, to a pair of crank levers 22, 23 pivoted to the leg at 26 and connected by a rod 21 to the heel behind a needle or ball bearing 14 interconnecting the shin and foot portions. As the wearer steps forward with the other leg, the foot portion 13 pivots about the bearing 14 relative to the shin to cause the rod 21 to move so that the chains 27 are loosened. As weight is transferred to the other leg and the foot portion 13 leaves the ground, the knee joint is free to bend so that the arms 28 and 31 move towards a cross bar 53 in the thigh portion 10. The arms 31 carry levers 48 which, as bending of the knee continues and the leg is swung forwardly, abut the cross bar 53 and are turned to push arms 28 forwardly away from arms 31 sufficiently for the spring 41 to be moved over its dead centre position. The spring then pulls the arms 28 and 30 towards one another so that firstly the arms 28 abut a second cross bar 54 in the thigh portion and thereafter the leg is straightened as the foot approaches the ground forwardly of the wearer. As the foot is placed on the ground, it pivots to its original position so that the rod 21 causes tightening of the chains 27 which pulls the arms 28 and 31 back to their original position. When the wearer desires to sit, the chains are loosened by raising the foot, the knee joint is bent to operate the parts as for walking but, as the foot carries the weight of the wearer, the spring 41 does not bring about straightening of the leg. As bending of the knee continues, the cross bar 54 in the thigh portion pushes the arms 28 and 31 rearwardly until the detents 49 ride rearwardly over the ratchet 50 and the spring 41 is moved rearwardly over its dead centre position so that it acts to hold the leg in a sitting position. In rising, a stop 56 in the thigh returns the parts to their original positions.
