Title: Control system for a crane electric motor
IPC: H02P7/34
Filed: 1974-08-21
Abstract: 1482225 Automatic control of cranes TOKYO SHIBAURA ELECTRIC CO Ltd 21 Aug 1974 [24 Aug 1973 (2)] 36766/74 Heading G3N A D.C. motor is controlled by a variable D.C. generator set which may be formed by a static converter arrangement. The motor speed control system includes a circuit for generating a load torque signal during an acceleration phase in dependence upon the motor armature current, the motor field strength and the rate of change of motor speed. The speed is controlled in accordance with the torque signal to achieve a desired postacceleration condition. As shown, a crane is driven by a D.C. motor 10 energized through thyristor convertors 13, 14 of opposite polarity. The converters are controlled by pulse generators 25, 26 in response to comparisons of signals derived from a speed feedback loop 36, armature current feedback loop 40, and a speed reference setting potentiometer 30. The reference signal is supplied by way of a limiting circuit 35 which ensures that the armature current is kept constant and which receives positive and negative signals representing a desired motor speed at the end of an acceleration phase. The signals are formed by a circuit 63 receiving inputs from a field current detector 53, the current loop 40, and a capacitor 67 which differentiates the speed feedback signal. An operational amplifier 69 forms a signal representing the load torque, and this signal is divided into a constant value set by a potentiometer 72 in a function generator 70 to produce the required signals for the limiting circuit 35. The motor field current control loop 52, 53, 57, 58, 59, 60 receives an additional component dependent on the armature voltage through devices 54-56. In a second embodiment, Figs. 2a, 2b (not shown), the main feedback loop is responsive to armature voltage rather than speed, and the output of function generator 70 is connected to the field current control loop. Another modification, Fig. 7 (not shown), includes speed responsive relay contacts which operate to connect comparison point 34 to potentiometer 30 at low speeds and to circuit 63 at high speeds.

Title: Improvements in coin selector devices
Inventor: BOURACIER CYRIL EUGENE
IPC: G07D3/00
Filed: 1967-08-11
Abstract: 1,236,394. Coin testing. ICE-MATIC Ltd. 27 June, 1968 [11 Aug., 1967], No. 37012/67. Heading G4V. A coin testing device comprises plates A, B pivotable about a pin 11 for the discharge of trapped coins, a gravity fed coin runway strip 15, a trap 12, 13, 14 for apertured discs at the entrance thereto and thereafter diameter and thickness test elements. One or other of plates A, B is fixably mounted, the mounting being such that the plates, which are normally parallel to one another, are both inclined to the vertical at a small angle. The coin runway strip 15 and the counter-balanced bent-wire trap 12, 13, 14, for retaining apertured discs are adjustably mounted in such a manner that the bottom of a disc is resting upon the reception end of the runway 15 at the same time as the wire end of the trap is projecting into any perforation in the disc. A bent plate 36 adjustably mounted on screw-and-slot means ensures that smaller diameter coins are always guided into the bentwire trap. The parts A and B are adjustable by means of a screw 28 to control a gap C, Fig. 1, between the inner face of part A and the adjacent face of the runway 15. An unacceptably thin coin will fall into the gap C on encountering the runway 15. Unacceptably thick coins are stopped by the tip 33 of a screw 31. A magnet 22 is provided to trap ferromagnetic coins. The distance between the top edge of the vertically adjustable runway 15 and the bottom edge 17A of a plate 17 determines the maximum diameter of coin acceptable to the device. A narrow plate 39 which is attached alongside the bottom edge of the plate 17 is adjustable in height by means of screw-and-slot devices 19 and also by virtue of the provision of extra holes 20 and a cut away portion in the plate 39, which may be inverted for purposes of adjustment. The bottom edge 18 of the plate 39 is normally adjusted in relation to the runway 15 so that its distance from the runway 15 is slightly less than the diameter of the coin to be tested and thus a smaller coin due to the angular inclination of the selector will fall out sideways and be held trapped in an adjustable side guard 23.

Abstract: 988,104. Repeaters. NORTHERN ELECTRIC CO. Ltd. Oct. 9, 1962, No. 38218/62. Heading H4R. A unit inserted in a long subscriber's line comprises a speech transformer 42, 48, a pair of transistors 21, 22 for repeating D.C. signals from the substation to the exchange and a transistor 23 for repeating ringing current to the substation. In the offhook condition a loop is closed between batteries 44, 45 and the change of potential at the point 47 renders the transistor 22 conducting. The transistor 21 conducts in turn and the loop to the exchange is closed through its emitter-collector path, and is opened by dialling impulses. The diodes 34, 36 and 33, 37 provide for the reversal of line current when the called party replies. Ringing current is applied by way of capacitor 52 to the base of the transistor 23 which provides substantial gain. The voltage thus applied to the subscriber's tip lead 17 in conjunction with that applied through capacitor 53 to the ring lead 18 operates the bell.

Abstract: 946,214. Automatic voltage control. GENERAL ELECTRIC CO. Ltd., and J. W. McPHERSON. Sept. 29, 1961 [Nov. 7, 1960; Dec. 22, 1960], Nos. 38231/60 and 44147/60. Heading G3R. A direct voltage stabilizer circuit 1 is supplied with a normal input and a standby input, e.g. of lower voltage, from a transformer 6 having a primary winding 5 connected to an alternating current source 4. The normal and standby inputs are derived from first and second secondary windings 7, 8 of the transformer and are respectively connected to the circuit 1 over rectifiers 9, 14 filters 10, 15 and switching transistors 11,16. The circuit 1 maintains a supply line 2 at a stabilized negative potential relative to an earth line 3 and comprises a series transistor 12 the conductance of which is controlled in known manner by an error sensing amplifier 3. In normal operation transistor 11 is biased into conduction and transistor 16 is cut-off by a bi-stable circuit 17 under the control of a voltage sensing network 18 connected across the filter 10; the transistor 12 then compensates for normal input voltage variations to maintain the output voltage constant. If, however, the input voltage increases to such a value that it would no longer be possible to stabilize the output voltage without damaging transistor 12, the signal supplied by the sensing network 18 changes the bi-stable circuit 17 from its first condition to its second condition whereby transistor 11 is cut-off and transistor 16 is rendered conductive so that the standby input of lower voltage is applied to the circuit 1 which can thereby operate to maintain the output voltage at the desired level. If the normal input voltage falls to a value within the normal range the network 18 and the bi-stable circuit 17 operates to restore the normal input to the circuit 1. The standby input may be of higher voltage than the normal input and only be used when the voltage of the normal input falls to a low value at which it would no longer be possible to maintain the output voltage at the required stabilized potential. Specification 946, 212 is referred to.
