Title: Apparatus for extracting bulk material from dumps
IPC: B65G65/02
Filed: 1975-09-26
Abstract: 1486657 Material reclaiming apparatus GUSTAV SCHADE MASCHINENFABRIK 26 Sept 1975 [28 Sept 1974] 39610/75 Heading B8E Apparatus for reclaiming material from a dump comprising a gantry 19 which runs on rails 18 longitudinally of the dump 12 for feeding material to a depot belt 17 has clearing means, e.g. in the form of a rope 32, for disloading material from the transverse face of the dump for removal by a scraper chain on an arm 25. In use as in Fig. 1 on the transverse face of the dump the clearing rope 32 is swung across the face by a winch 36 connected by a cable 37 to a centre point of the rope 32 to dislodge material to be fed by the conveyer chain to the belt 17. Weights 35 acting on spare rope 32 keep it taunt while allowing variation in its length during operation. With the rope 32 raised clear of the dump the chain conveyer can be raised by a hoisting cable 28 to engage the longitudinal lateral slope 11 of the dump, Fig. 4, to feed material therefrom directly to the belt 17. With the chain conveyer also raised clear of the dump the apparatus can be moved thereover to other dumps or operating points. If desired clearing means can be provided on both sides of the gantry so that it can operate in either direction. In Fig. 7 the clearing rope is replaced by a rod or beam 70 having teeth 79 slidable in a sleeve 72 and mounted for swivelling across the face 12 by a winch 76 connected by a rope 75 to a carriage 73 mounting the sleeve 72 and movable up and down a guide 74. Two chain conveyers may be provided mounted on arms 90, 91, Fig. 11, which may run in opposite directions to feed belts 17, 17<SP>1</SP> or in the same direction to feed from one to the other and thus to a single belt 17. This arrangements allows both slopes 11, 11<SP>1</SP> to be operated on at the same time. A stacking conveyer 100, Fig. 12, pivotally mounted at 102 on a bracket 101 and fed from a loop carriage on the belt 17 may be provided to form a dump as the gantry moves, with both extracting means raised to the inoperative position.

[Also in Divisions G1, H4 and H5] A method of producing holographic information comprises producing and receiving an object signal by scanning a point source 30 of coherent wave radiation over a plane 29, Fig. 2, each point on the source plane effectively illuminating the entire object scene and receiving the object signal at a fixed point 27 in space, and mixing the object signal with a reference signal coherent therewith to produce the holographic information. Both the object signal and reference signal may be received directly at position 27 and the hologram recorded there, or the object signal from position 27 may be electronically mixed with a reference signal 33, Fig.2A to give a holographic interference beam 35. The radiation used may be visible light, ultraviolet light, infrared radiation, radiofrequency radiation, modulated electro-magnetic radiation, x-ray radiation, microwave, seismic, ultrasonic, hypersonic radiation or phonons. Specific applications mentioned are the use of an ultrasonic hologram of a human stomach to determise the existence of any disorders and in non- destructive flaw detecting in objects e.g. ceramics, using infrared with a refrigerated infrared detector.

Abstract: 1440995 Valves S HUSTED-ANDERSEN [trading as TRANSCODAN SVEN HUSTEDANDERSEN] 30 Aug 1973 [30 Aug 1972] 40974/73 Heading F2V In a pinch-cock for medicinal purposes flow is controlled by varying the width of the constriction formed in a flexible tube 8 compressed between a fixed surface and the surface of a roller 2 which moves with a constant spacing from the fixed surface. The width of the constriction is varied by providing a groove 11 the width of which varies as the roller moves forward to the position in which flow is cut off. A raised step 9 on the fixed surface ensures that the bend 10 is tightly clamped to prevent flow in this region. The roller is guided by grooves in the side walls of the device and at the left-hand and, as seen in Fig. 2, the grooves widen to allow the roller to move away from the fixed surface permitting easy insertion of the tube 8 which may be of plastics material. The tube may be completely clamped off by pushing it into a slot 20 without having to adjust the position of the roller.

Title: Improved intercoupling of a.c. electric networks
Inventor: JONES KENNETH MEIRIG
IPC: H02H9/02
Filed: 1965-09-29
Abstract: 1,149,525. Coupling arrangements for A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 19 Sept., 1966 [29 Sept., 1965], No. 41336/65. Heading H2H. In a coupling arrangement between two A.C. networks of the type in which an L/C combination provides for a low impedance path under normal operating conditions and automatically increases the reactive impedance to prevent excess current flow upon the occurrence of abnormal (fault) conditions, a modifying circuit is provided to ensure that the normal (low) impedance of the coupling is rapidly restored as soon as the fault has been cleared. In Fig. 2 the L/C combination 4, 5 is normally series resonant to present a low impedance, but should a fault occur a switch 7 is closed to connect a damping resistor 14 and a non- saturable reactor 6 which de-tunes the coupling. When the fault has been cleared a signal from a control unit 10, obtained for example by monitoring the coupling current at point 11, closes a fast-action switch 9 to connect a capacitor 8 and damping resistor 15, members 6, 8 forming a high-impedance parallel-resonant circuit which restores the low impedance of the series resonant circuit 4, 5 and facilitates the subsequent opening of the switch 7 and the switch 9 in that order. The switch 7 may be omitted if the reactor 6 is replaced by a saturable reactor (36), Fig. 1 (not shown), which automatically de-tunes the combination 4, 5 when a fault occurs. In another arrangement, Fig. 3 (not shown), of the type in which members 4, 5 are in parallel, with member 4 alone forming the coupling impedance for normal operation and the combination 4, 5 forming a high impedance parallel-resonant circuit under fault conditions, the capacitor 5 is connected in parallel with a non-saturable reactor (16), through the fast-action switch, when the fault has been cleared. Two other arrangements are described one of which, Fig. 4 (not shown), is generally similar to the circuit of Fig. 2, but the combination 4, 5 is in parallel with a resistor (26) which forms the coupling impedance when members 4, 5 are de-tuned by closure of the switch 7. The other arrangement is shown in Fig. 5 and uses parallel-connected seriesresonant circuits 4a, 5a; 4b, 5b which normally by-pass a resistor 26 through a switch 47 to provide a low coupling impedance. Excess current causes closure of a switch 48 to increase the coupling impedance. After fault clearance the switch 47 is opened, followed by opening of the switch 48 and reclosure of switch 47 for normal operation. The switches used in the various embodiments may be of vacuum, sparkgap, valve or semi-conductor type, and their operation may be controlled by current parameters such as actual value, change of value or rate of change, or by the voltage across the capacitor 5.
