Filed: 1960-09-20
Abstract: 902,317. Electromagnetic switches. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 20, 1960 [Oct. 22, 1959], No. 32307/60. Class 38 (5). A manually-operable circuit-breaker having an operating handle projecting from a casing is combined with an electromagnetic operating mechanism having a length not substantially greater than the length of the circuit-breaker casing and a depth not substantially greater than the depth of the casing and handle. The handle 5 of the circuit-breaker 2 is movable between slot ends 54 and projects between spring wires 11 secured at 11<SP>1</SP> to a lever 6 pivoted at 14 and an opening 10 through which the handle 5 projects. Portions 8, 9 of the lever 6 are recessed at 34, 34<SP>1</SP> to allow room for movement of a U-shaped lever 21 pivoted at 28 and a tension spring 31 having its ends secured to the lever 6 at 33 and to the lever 21 at 29. A pin 42 projects from the lever 21 between to coupled plunger armatures of respective electromagnets 37, 38. When the electromagnet 37 is energized the pin 42 is moved downward rotating the lever 21 anticlockwise until the spring 31 crosses the centre line of the lever 6 and snaps the lever 6 clockwise to operate the circuit-breaker 2. During this movement a screw 48 on the lever 6 operates a change-over switch 43 to. disconnect the coil of the electromagnet 37 and prepare the circuit of the electromagnet 38 for a subsequent operation (Fig. 3, not shown). During such operation a screw 49 on the lever 6 operates the change-over switch 43 in the other direction.

Abstract: 933,116. Stranding machines. EDMANDS CO. Sept.12, 1961 [Nov. 25, I960], No. 32696/61. Class 109. A cradle for a planetary cable stranding machine comprises a frame as shown in Fig. 1 in which one side 17 can be swung open about a hinge 18 to expose a reel shaft 20 having one end permanently but rotatably mounted in the opposite side 12. The side 17 has two projections at its free end such that when it is swung to its closed position these projections overlap the top and bottom surfaces of an end wall 19, the wall 19 housing upper and lower spring- biased latch members 43 that are tapered at their exposed ends such that they are initially biased towards each other by the projections on side 17 as this side is being shut, and such that they then move apart to engage in openings 36 in said projections to lock the side 17 in its closed position. Each latch member 43 has a pin 51, 52 that extends out through individual elongated slots 53, 54 in the side face of the wall 19 and by using a key 57, as illustrated in Fig. 3, such that a central recess 60 in the key is fitted on to a central stud 55 on the wall 19 and such that the pins 51, 52 extend into cam-shaped slots 59 in the key, the side wall 17 can be released by turning the key to force the pins 52, 53 towards each other and thus withdraw the latch members 43 from the openings 36 in the side wall 17. A wheel 21 is fixed to the shaft 20 and is equipped with a brake cord 22 for retarding its motion as desired. A reel can be held on the shaft 20 by applying a nut to the threaded end of the shaft. The free end of the shaft 20, and the bearing 25 therefore, may be curved, i.e. cupshaped to enable the shaft 20 to freely enter the bearing 25 when the wall 17 is closed.

Title: Apparatus for applying electrical connectors
IPC: H01R43/027
Filed: 1964-08-12
Abstract: 1,013,318. Applying electrical conductors to terminal posts. AMP Inc. Aug. 12, 1964 [Aug. 19, 1963], No. 32794/64. Heading B3A. Apparatus for applying an electrical connector clip on to a terminal post comprises a clip pusher actuating means for reciprocating the clip pusher and coupling means therebetween, and the coupling means comprises an overload release coupling and a releasable rigid coupling, the overload coupling being operable when the rigid coupling is disengaged. The clips are fed over the surface 64 of a bar 66 on to a reciprocable slide 52, which lifts the clip on to a T-shaped mandrel 32. A wire receiving recess 34 is located in the mandrel and the wire and clip are guided on to a terminal post by spring clips 50 which are clipped thereon. The apparatus is actuated by a pneumatically operated piston, the rod 84 of which is mounted on a block 90. The slide 52 is actuated by a rocker 60 which is actuated in turn by a spring 91 on the block 90 such that forward movement of the block causes counterclockwise movement of the rocker after the spring 91 has passed the pivot 62. The block 90 also engages a slide block 72 to position the leading clip on the slide 52. The clip is advanced by a pusher 80, which is coupled to the piston-rod 84 by a pair of coupling blocks 86, 88. The block 86 is coupled to the piston-rod 84 by an ear 93 engaging in a recess 94 and the block 88 is slidably received in a channel 96 in the block 86. The blocks 86, 88 are rigidly coupled together by a spring- loaded latch 100 on an arm 102 engaging an ear 98. The forward end of the arm 102 is formed as a cam which engages a fixed block 110 (Fig. 2), to be pivoted so as to disconnect the latch 100 and ear 98 as soon as a clip has been pushed from the mandrel 32 on to the terminal post. A roller 112 on a spring-loaded lever 114 engages in a groove 116 and acts as an overload release coupling. The rigid coupling is disconnected as a clip moves on to the terminal post, but the blocks 86, 88 still move together by means of the overload coupling. Should the passage of the clip be obstructed the latter coupling is released and the block 86 completes its stroke while the block 88 remains stationary. On the return stroke, the rear face of the block 88 engages a surface 74 of a fixed block 76 and is stopped from further movement. The block 86 continues to move until the two blocks are restored to their original relative position. Specification 956,118 is referred to.

Abstract: 1436255 Semi-conductor devices SONY CORP 12 July 1973 [13 July 1972] 33389/73 Heading H1K A semi-conductor device comprises a plurality of parallel rod-shaped vapour-deposited semiconductor crystals of one conductivity type packed together with grain boundaries between, a first electrode connected to one end of the crystals and a second electrode connected to the grain boundaries. Typically the device is a field effect transistor, Fig. 7E, formed on an NN + silicon structure by deposition of silicon from silane, silicon tetrachloride or silicon dihydrogen dichloride first at specified temperatures to produce a polycrystalline nucleating layer and then at higher temperature to grow the rod shaped crystals thereon. Subsequently acceptor impurity is diffused through a frameshaped aperture in oxide masking to form a similarly shaped P + gate contact region and by lateral diffusion a P-type gate region around each separate crystal. N+ source region 26 is then formed by masked diffusion and drain electrode 29 provided. In an alternative form a monocrystalline grid is deposited at the same time as the rod-shaped crystals to divide these into several groups. Acceptor impurity is diffused into the grid to form a gate contact and laterally as before to dope the rods, each group of which has its own source electrode interconnected with the others, while the substrate forms a common drain region. Use of the devices as resistors and voltage variable capacitors is suggested, as is an equivalent arrangement in which diffusion to form the PN junctions in the grains is dispensed with. Sapphire, spinel; quartz, molybdenum and tungsten may alternatively be used as substrate materials.

Mineral-mining apparatus consists of a cutting machine having positioned to one side of the body 7a of the machine two contra-rotatable cutter drums 14, 15 so that mineral mined by the drums is carried by the drums through the gap 21 between the drums and discharged into a suction conveyer 9, the intake end 10 of which is secured to and drawn forward by the body of the machine. The upper drum 14 is pivotal about the axis of the lower drum 15 and may be moved radially of this axis so that the gap between the drums can be varied to suit the produced particle size of the mineral. The mineral is removed from the main suction pipe before reaching the end of the pipe by a branch pipe extended into the main pipe through a longitudinal slot in the main pipe, the slot being sealed off around the branch pipe by flaps as it moves relative to the main pipe during the advance of the cutting machine.
