Abstract: 845,054. Automatic speed control systems. SCHLOEMANN A.G. June 3, 1958 [June 13, 1957], No. 17674/58. Class 38 (4). [Also in Group XXIX] In a double-billet extrusion press 1, in which two pistons 2, 3 are actuated by variable delivery pumps 6, 7 having adjusting appliances 50, 54 and driven by a motor 56, the speeds of the pistons are maintained equal by varying the delivery of the pump 7 in response to a signal derived from a differential gear 17, 18, 19 connected to the pistons. Racks 17, 18 are coupled through a pinion 19, journalled in bearings carried by a lever system 20, 23, 25 so as to move a sliding arm 27 of a potentiometer R1 when the piston speeds are unequal. Potentiometer R1 and a potentiometer R2 form a Wheatstone bridge; an out-of-balance signal actuates a relay 35 controlling the direction of rotation of a motor 40 driving through a worm and wheel 43, 44, a rack and pinion 47, 45 on which is mounted a slider of the potentiometer R2 and a pivot 48 of a lever 49. Adjustment of the pivot 48 varies the delivery from the pump 7 so as to restore the equality between the piston speeds. The piston speed is set by mechanical displacement of a coupling arm 51. For zero delivery levers 52, 49 and rack 47 are parallel, so that movement of pivot 48 has no effect. In addition, a pivot 55 may be adjusted by a similar arrangement as that for pivot 48, the pivots being moved in opposite directions to correct for a difference in speeds.

Abstract: 1,068,926. Electric indicating systems. ELECTRONIC MODULES (DESIGNS) Ltd. April 9, 1965 [May 7, 1964], No.19137/64. Heading G1N. In a servo system of the type in which a movable member, e.g. a weigh beam 1, is maintained at a balance point by means of an electric circuit which causes a restoring force to be applied to the member in opposition to any force tending to move the member from the point, a coil 2 movable with the member co-operates with a fixed coil 3 to form an induction transducer which detects movement of the member from the balance point and produces a signal representing the position of the member, and the coil 2 also produces a signal representing the velocity of the member. The restoring force is exerted by a further coil 4. The coil 2 is energized by a square wave generator 6, and the position signal induced in the fixed coil 3 is fed through an amplifier 8 to a servo-amplifier 11 powered by a square wave generator 21. The velocity signal is generated in the coil 2 by a fixed permanent magnet 5 and is passed through a filter 15 and amplifier 17 to the servo-amplifier 11 where it is mixed with the position signal to provide critical damping. The output of the servo amplifier 11 is further amplified by a D. C. amplifier 26 and fed through a current reference resistor R to the restoring coil 4 which is mounted on the other end of the beam 1. The coil 4 is provided with a fixed centre-pole permanent magnet 7 to achieve a linear field distribution over the range of working movement, so that the voltage V fed to the coil 4 is proportional to the weight to be measured by the beam. Detailed transistorized circuits for the system are illustrated in Fig. 2  (not shown).

Abstract: 746,656. Hydraulic vehicle brakes. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. June 30, 1954 [July 3, 1953], No. 19204/54. Addition to 687,793. Class 103 (1). The release device for spring accumulator brakes, as described in the parent Specification, has a modified hydraulic piston pump which will provide a controlled release of hydraulic fluid so as to provide a sensitive actuation of the brakes by the main application spring. This characteristic is provided by slidably mounting within the pump piston 7a, a ram 102 with a projecting spindle carrying a double cone 105. If the lever 5a is depressed sufficiently to deflect a leaf-spring 112, the cone 105 will spread apart the adjacent ends of pins 106 and 107 and be locked between them, this action causing a permanent opening of valve 108 sufficient to allow liquid to be released for light braking. This pressure can be modified by moving the plunger 7a up and down within the limits of the pin and slot 103, 104, so that ram 102 is not displaced.

Title: Improvements in trolley pole safety appliance for electric tramcars and the like
IPC: B60L5/14
Filed: 1923-07-27
Abstract: 223,663. Lacey, J. July 27, 1923. Releasing devices for collectors. - Relates to trolly pole safety appliances for electric tramcars and the like of the type in which the pole is controlled through a pawl 29 by a spring 25 tending to raise the trolly wheel, and in which, when the trolly wheel leaves the wire and consequently rises beyond its proper working height, the trolly pole is disconnected from the spring and falls to a safe level. The trolly pole 13 is mounted about a horizontal pivot 15 on the lever 16 which is itself pivoted about a horizontal pivot 17 to the standard 12 and is under the control of the trolly spring. The lever and the standard are provided with the co-operating abutments 26, 27 which, when the pawl is released, are brought into contact by the action of the trolly spring and limit the movement of the lever 16. The pole and lever are also provided with the co-operating abutments 45 .. 47 which are brought into contact by, and limit, the falling movement of the pole. When the trolly wheel rises above the normal working height and the pawl is consequently disturbed, the frictional brake 50, which resists translatory rotation of the pole, is immediately operated from the trolly pole spring through the action of the bolt 19, the lever 16, the tooth 52 and the upper end 51 of the brake lever 49. To retain the pole at the safe level, the pole carries a tooth 40 and the lever a cooperating catch 37 which have their co-acting faces 41, 38 of such formation that whereas a slow upward movement of the pole moves the catch into the releasing position, a sharp upward movement does not. In the application of the invention to existing trolly-poles, the pole is cut between its ends, usually near the standard, and the mechanism is inserted in that position.
