Title: Automatic control means for controlling the speed of traction motors and vehicles fitted with such means
IPC: B60L15/20
Filed: 1972-06-28
Abstract: 1389084 Automatic control of speed ENGINS MATRA 28 June 1972 [29 June 1971] 30311/72 Heading G3R Speed of a traction motor is automatically controlled by a system which receives speed demand signals and compares them with signal representing the actual speed to provide a difference signal which is used to select a parameter representing the allowable rate of change of acceleration or deceleration which parameter is integrated and limited and is used to control the motor. The value of the rate of charge of acceleration parameter and the limit imposed on the rate of acceleration signal are chosen to give a comfortable ride for the passengers and typically are o.6 m/su<SP>3</SP> and 1.3 m/su<SP>2</SP> respectively. In the system shown the required speed signal VE is compared at 4 with the vehicle speed VS to produce a signal which is further compared with a rate signal in comparator 7 giving the signal E which is used in means 8 to select which value should be provided for the rate of change of acceleration #γ. The value of #γ that is chosen is either for maximum rate of change of acceleration, zero or maximum rate of change of deceleration. The signal #γ is integrated at 9 and limited by the parallel limiter 10 which fixes the maximum value L of acceleration and the maximum value L<SP>1</SP> of deceleration and the resulting acceleration signal γ e  is compared with the actual acceleration of the vehicle derived from the vehicle speed VS when differentiated in 5. The multiplier K2, whose value is 10 ensures that changes in mass of the vehicle do not affect the control system operation, provides the useable acceleration signal γ c  which supplies amplifier 3 for controlling motor 4. In a modification, Fig. 5 (not shown) a closed loop speed control system is used for the motor and the incoming acceleration signal applied to the loops is integrated to provide a speed signal.

Abstract: 1392620 Cinematography EASTMAN KODAK CO 29 June 1972 [29 June 1971 (2)] 30579/72 Heading G2E In a cine projector (or other web handling apparatus) in which a film is taken from a supply reel 12 to a film gate 14 two sensing devices are provided. When both these devices are both detecting particular effects in the feeding of the film which normally occur only at the end of projecting a film the film is rewound on to the reel 12. These devices are a film snubber 18, which responds to excessively high film tension by the pivoting of the arms 20, 22 about stud 28 so that tab 38 closes switch 42, and an arm 48 having a curved end 60, which when it detects the film lying along a radial path from the reel 12 pivots about stud 46 so that a tab can close switch 58. The switches 42, 58 are arranged in series in a circuit for activating a solenoid which switches the film feeding drive into reverse. The switches 42, 58 are prevented from being normally closed by springs 36, 50 respectively. In another embodiment the switches are replaced by two electrical contacts movable in intersecting planes. Each contact is moved in its respective plane by the snubber 18 or arm 48. When both the devices 18, 48 register the increase in film tension and the film lying radially of the reel then the contacts are brought together and the solenoid activated.

Title: Frictional drag apparatus and brake provided therewith
IPC: F16D65/54
Filed: 1958-09-25
Abstract: 862,402. Locking rods. GOODYEAR TIRE & RUBBER CO. Sept. 25, 1958 [Oct. 11, 1957], No. 30643/58. Class 80 (3). [Also in Group XXXIV] Axial movement in either direction of a rod 4, Fig. 1, slidable in a block 1 is frictionally resisted by an apertured disc 5 which is canted by two oppositely acting springs 9, 10 to grip the rod, the axial thrust on the rod which produces slip in one or other direction being determined by the respective strengths of the two springs. The different spring strengths may be adjusted by screws 11, 12. Opposed fulcrum surfaces 15, 16 for the disc may be provided by screws 17, 18 which are adjusted to provide a small clearance. In a modification an apertured disc 66, Fig. 3, on a rod 52 is canted by springs 62, 64 in the form of bowed rings, each of which is secured at one point only by a screw whose head forms a fulcrum for the disc. The springs 62, 64 are of unequal strength so that the disc 66 provides a high frictional resistance to movement of rod 52 to the right and a low resistance to movement to the left. The spring 62 is attached to a flanged disc 60 which is clamped by a threaded cover to a cylinder head 45 carrying the spring 64, a dowel pin 65 on the cover entering a selected locating hole in the head to provide angular adjustment of the disc 60 and hence adjustment of the spring effect. As shown, the rod 52 forms an automatically adjustable stop for a piston 43 in a disc brake wherein a disc 37 slidably keyed at 39 to an aircraft or other wheel 36 is clamped between a pad 41 on a fixed support 40 and a pad 42 on the piston 43. The piston return spring 49 reacts against a flange 51 on the rod 52, which flange forms a stop for the piston when the brake is retracted. The position of rod 52 thus determines the brake clearance. The stronger spring ring 64 causes the canted disc 66 to prevent movement of the rod 52: to the right under the reaction of the spring 49 as the brake is applied. As the brake pads or disc wear, however, the piston travel increases until a ring 50 thereon strikes the flange 51 and overcomes the high resistance of the canted disc 66 to shift the rod 52 to the right to restore the desired brake clearance. Should this shifting movement be too great, due for example to distortion of the disc 37 or support 40, so that the disc 37 rubs on the pads when the brake is released, the rod 52 is able, due to the low strength of spring ring 62, and the consequent low resistance of the canted disc 66, to be automatically pushed back slightly until rubbing contact between the brake disc and pads ceases.

Abstract: 266,826. Scholl Manufacturing Co., Ltd., and Temy, E. Dec. 5, 1925. Foot-arch supports.-The cover or insole of a foot-arch support consists of a single integral layer of material so fashioned by cutting as to constitute a complete or partial upper covering for the metal plate and also a partial under covering therefor. In the form shown in Figs. 1 and 2, the leather insole 3 is incised in the manner shown so as to form a pocket for the forward end of the metal support 4. In modifications a metal support comprising two superposed plates may be used, or the insole may be cut so as to form also a pocket for the heel of the plate, or so as to overlap the whole of the edges of the plate. In another form, Fig. 8, the insole is split at the front to form two layers, the lower of which is cut transversely so that the end of the metal plate may pass into the space beween the two layers. The inner surfaces of the two layers may receive a coating of protective material such as plastic celluloid and may be marginally united by a similar material or other adhesive. In any of the modifications the forward end of the metal plate may be covered with a plastic protective medium or inserted in an auxiliary pocket of metal, leather, canvas, or other material, or the pocket formed in the insole may have an auxiliary lining of such materials. Fig. 11 shows a further modification in which the metal support 4b passes through a slit in the insole 3 so that its end bears on the upper surface of the insole, which is skived at 8 to form a smooth foot-engaging surface.
