Filed: 1962-03-02
Abstract: 989,854. Cores for dynamo-electric machines. LICENTIA PATENT-VERWALTUNGSG.m.b.H. March 2, 1962 [March 6, 1961], No. 8204/62. Heading H2A. The noise of a dynamo-electric machine is reduced by mounting the stator stack 1 in frame by resilient means, e.g. tangential strips 3, the frame 8 being composed only of annular radially extending webs 5 connected by longitudinal webs 4, also extending in the radial direction, so that the frame is open in the radial direction and presents little area for the propagation of sound in the radial direction. Instead of tangential springs 3, a cylindrical shell of resilient material may be placed between the core and frame. The open outer surface of the frame is closed by thin cylindrical shell secured to the frame by weak springs (Fig. 4, not shown). This cover may be covered with drone-preventing material.

Abstract: 914,601. Automatic circuit-breakers. BARDEN, A. E. (I-T-ECircuit Breaker Co.). March 12, 1959, No. 8663/59. Class 38. (5). A high-speed D.C. circuit-breaker has a movable contact 70 held in its closed position, Fig. 10, by a releasable magnetic latch or coupling against the action of an opening spring 138, the latch or coupling comprising a pair of co-operating movable magnetic members 72, 92, one connected to the circuit-breaker operating mechanism and the other to the movable contact. The members 72, 92 are normally maintained in engagement with each other by the flux set up by a magnetizing coil 84. The movable contact 70 is moved from its open position, Fig. 12, to its closed position, Fig. 10, by a solenoid (not shown) moving a toggle 142, 148 into its over-centre position where it abuts a fixed stop 168, the member 72 and a lever 106 carrying the member 92 turning about a fixed pivot 98 to close the contacts. A fixed magnetic shunt 212 which links with the main current path through the contacts 70, 132 has an air gap in which the magnetic member 72 is located. In the event of a reverse current, the flux produced in the magnetic shunt 212 counteracts that due to the coil 84 and the spring 138 is able to separate the members 72, 92 and open the contacts, Fig. 11. A spring 160 is now able to collapse the toggle under the control of a dashpot (not shown) associated with the closing solenoid to reset the members 72, 92, Fig. 12. When the contacts are opened by the spring 138, rebound is prevented by a pivoted latch (not shown) carried by the member 72. The Complete Specification describes and illustrates in detail a constructional arrangement of the circuit-breaker.

Abstract: 1,026,334. Momentum power-storing apparatus; controlling clutches. FERNSEH G.m.b.H. March 7. 1963, No. 9069/63 Headings F2L and F2X. A rapid starting device for a film transport mechanism, which in operation is driven at a specified speed by a synchronous motor (not shown), comprises a flywheel 6, driven at an initial speed substantially greater than the specified speed, and a friction clutch 9 which when engaged connects the flywheel to the drive shaft 8 of the mechanism, the flywheel moment of inertia and initial speed being such that on clutch engagement the mechanism is accelerated to the specified speed as the flywheel decelerates to that speed. Preferably the moment of inertia of the flywheel and its driving means equals the moment of inertia of the mechanism and its motor, and the flywheel initial speed is twice the specified speed. The flywheel 6 is driven through a flexible coupling 2, 4, by a motor 1. The clutch plate 9 is keyed, with some axial freedom, to the shaft 8 and is engaged by the action of a fixed electromagnet 14 on an armature 13 of the clutch. In the clutch control circuit (Fig. 2, not shown) a low voltage D.C. supply charges a capacitor C through a high resistance R. Simultaneously with switching on the synchronous motor of the mechanism, a switch S is closed to discharge the capacitor through the coil 15 of the magnet 14 to engage the clutch. When the capacitor is discharged, the current in coil 15 falls until the clutch spring 11 is able to disengage the clutch, this being arranged to occur just after the mechanism has reached the specified speed.

Abstract: 116,892. British Westinghouse Electric & Manufacturing Co., (Assignees of Mateer, J. E., and Macdonald, H. G.). June 8, 1917, [Convention date]. Insulators.-Electric insulator bushings of the condenser type are formed with insulating layers of uniform length and interposed conducting layers of various lengths. In the construction shown in section in the Figure, the high tension conductors 2 are threaded through a central micanite tube 3 upon which is wound a conducting layer 4, preferably tin foil, which in turn is surrounded by an insulating layer 5. The conducting and insulating layers alternate, but, whereas the conducting layers become shorter from the inside to the outside of the bushing, the insulating layers are all of the same length, thus producing a cylindrical bushing. The lengths of the conducting layers are so related to their diameters as to give uniform area throughout. When used out-of-doors, the bushing is further protected by insulating rings 6 and a filling 12 of insulating gum. Electrical connexions may be made to an external circuit from a metal cap 13.
