Title: Improvements in or relating to electric circuit interrupters
IPC: H01H33/18
Filed: 1936-03-09
Abstract: 462,495. Liquid - - break switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. March 9, 1936, No. 7123. Convention date, March 8, 1935. [Class 38 (v)] In a liquid-break switch, the arcing contacts are separated between a pair of opposed plate members of insulating material which define two of the side walls of an arc chute, and means are provided for causing the arc to be moved laterally within the chute during the arcextinguishing operation, the plates being placed so close together that the arc is in intimate contact with both of them and acts as a piston when moved laterally, so that a quantity of dielectric liquid is caused to flow through the chute to assist in the extinction of the arc. The invention is shown as applied to a threephase double-break switch contained in a tank 1 provided with a cover 3 carrying three pairs of insulating bushings 7 for the current conductors 31. The stationary contacts comprise main contacts 33 and arcing contacts 35 connected by bolts 36 to L-shaped members 29 secured to the ends of the conductors 31. The bolts 36 also serve to secure the arc extinguishers, each of which comprises a pair of outer insulating plates 57, a pair of plates 59 of iron or other magnetic material and an inner pair of insulating plates 61. The magnetic plates 59 are connected together by a square rod 63 of magnetic material. The phases are separated by members 23 of insulating material placed in the lower part of the tank. The movable contacts comprise a separate bridging structure 13 for each phase, each of the bridging structures being supported on an insulating rod 15. The three rods 15 are interconnected by a member 17 connected through a universal joint 21 and a link 19 to the operating mechanism of the switch. Each bridging structure includes a main bridging portion 37, in the form of a channel-shaped member of conducting material having contacts 39 for engaging the main stationary contacts 33, and an auxiliary bridging portion 41 carrying arcing contacts 43. The main bridging portion 37 slides on a cylindrical guide member 45 secured to the adjacent operating rod 15 and is biassed towards the fixed contacts by a spring 51, the relative movement between the bridging member and the rod being limited by an enlargement 47 of the guide member 45. The auxiliary bridging member 41 is mounted on studs 53 carried by the member 37, and is biassed towards the fixed arcing-contacts 35 by springs 55, the arrangement being such that on opening the circuit the main contacts separate before the arcing contacts. When the arcing contacts separate, the current follows a path looped around the portion 63 of the magnetic member, and the magnetic field set up moves the arc laterally between the plates 61. The latter may be made of a material capable of evolving an arc-extinguishing gas, such as horn fibre.

Title: Photographic camera diaphragm shutter
IPC: G03B7/081
Filed: 1966-02-22
Abstract: 1,092,687. Diaphragm shutters. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. Feb. 22, 1966 [March 11, 1965], No. 7663/66. Heading G2A. The shutter blades 2 of a photographic diaphragm shutter are driven by means of a displaceable permanent magnet 5 which interacts with an electromagnet 6, 7 having reversible polarity, the separation of the poles 6a, 6b of the electromagnet being variable, which variation determines the effective aperture. When the diaphragm value is set by means of a disc 9 and mark 30, a yoke 8 of the electromagnet is displaced to the left or right, hence varying the distance between the poles 6a, 6b. The exposure time is selected by setting a disc 11 against a pointer, thereby varying the resistance of a rheostat R which is part of an RC circuit. Depression of a button 14 allows a lever 12 to rotate anti-clockwise (as shown) and change over a switch 10 causing current to flow from a source E via a transistor T, through the section 7a-7c of the electromagnet coil 7 back to the source and also causes the condenser C to start charging. The current through the coil 7 magnetizes the core 6 setting up a south pole at 6a, thereby repelling the permanent magnet 5 towards the pole 6b. Movement of a coupling rod 4 on which the magnet 5 is mounted causes both the shutter blades 2 to pivot anti-clockwise (as shown), thereby uncovering the exposure opening 1 to a greater or lesser extent, depending on the position of the pole 6b. The rod 4 is followed part way by a spring-biased rocker arm 18 and a connecting rod 16. The shutter remains open until the condenser C is charged sufficiently to cause a transistor T 2  to conduct, which time depends on the resistance of the rheostat R. When T 2  conducts, T 1  is cut off and a transistor T 3  also conducts, thereby causing current to flow through the section 7b-7c of the coil in such a manner as to reverse the polarity of the poles 6a, 6b. The permanent magnet 5 is repelled from the pole 6b and moves to the right Fig. 2 (not shown) thereby causing the rod 4 to turn the blades 2 clockwise (Fig. 2) to close the aperture. Movement of the rod 4 entrains the arm 18 and rod 16, causing the rod 16 to move to the right (Fig. 2) thereby rotating the lever 12 to return to its position of Fig. 1, and allowing the button 14 to rise under the action of a spring 15. This breaks the circuit of the electronic switching device. A photo-electric resistance and a variable capacitor may be used in place of the present rheostat and condenser. A film sensitivity setting member may be mounted on the member 9. In another embodiment, Figs. 3, 4 (not shown) a permanent magnet and an electromagnet of reversible polarity may be used in an electromagnetic driving system for a multiblade shutter. As shown, five blades (2') are mounted on a single blade ring (4'), ring and blades moving in opposite directions to open and re-close the exposure aperture, the width of which is varied as before.
