Title: Automatic electric circuit breakers
IPC: H01H71/16
Filed: 1962-11-08
Abstract: 993,285. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 8, 1962 [Nov. 15, 1961], No. 42189/62. Heading H2B. On overload a latching bimetal strip 101 heats up and flexes to allow operation of the breaker mechanism 15 via a pivoted releasable member 81, strip 101 having a bimetal strip 112, which may be lanced out, projecting normally therefrom and acted upon by an adjusting screw 105 to adjust the tripping point, over - adjustment being prevented by stops for the member 107 rotating the screw 105. Bimetal 101 is heated by a plugin heater unit 61 and is compensated for ambient temperature variation when strip 112 projects in the opposite direction from bimetal 101 (Fig. 6, not shown). An operating handle structure 77 includes a U-shaped operating lever 85, pivotally supported at 87, having two U- legs 93 receiving pins on the arms of a V-shaped contact operating member 79 connected with the releasable member 81 by an over-centre spring 83. Pins 53 on member 79 engage in elongated slots 51 of movable contact plates 47 slidable into and out of bridging engagement with fixed contacts 33, 37, and rockable for self-aligning thereon. Plates 47 complete the circuit between terminals 31, 45, and the plug-in heater unit 61 connects contacts 39, 43 in the circuit. The breaker is re-set by a detachable handle 89 and is operable manually thereby. An indicator lamp 19 is protected by a removable plastic cap 157. The breaker housing comprises four sections and has mounting brackets 23. Specification 993,284 is referred to.

Title: Pulse counters having a magnetic pole wheel
IPC: G06M1/10
Filed: 1974-09-27
Abstract: 1474477 Electromagnetic counters N KOKKINOPOULOS 27 Sept 1974 [28 Sept 1973 20 July 1974 1 Aug 1974] 42201/74 Heading G4D A pulse counter comprises an electromagnet 13 having polepieces 16, 17 acting on a magnetic wheel 1 formed with regularly spaced poles 1a-1d, energization of the magnet causing rotation of the wheel 1 through a first angle α; a resilient biassing arrangement (Fig. 4) which when energization ceases causes the wheel 1 to rotate through a further angle # in the same direction; and numeral wheels to indicate the number of pulses, the angle α+# constituting one unit and # being substantially larger than α. The biasing arrangement, Fig. 4, comprises a square cam 5 on the shaft of wheel 1 and two flat blade springs 19, 20, one 19 being shorter so that when the cam 5 turns through angle α its end 19a snaps over the corner of the square and thereafter urges the cam to continue movement in direction F until the blades lie flat along the sides of the square. A gearing, Fig. 6, between a wheel 18 on the shaft of wheel 1 and the first numeral wheel 31 causes the latter to turn through 36 degrees for a 90 degree turn of wheel 1. The shape of wheel 18 and a transmitting wheel 40-41 prevents the numeral wheels 3 from being altered manually. In a modification (Figs. 7-9, not shown) the biasing arrangement differs: the earn 5 has two concentric squares, the smaller having small teeth at its corners, and the spring blades are replaced by a spring urged pivoted blade which co-operates with the large square to hold to wheel 1 in the rest position and has a long curved extension which acts on the teeth to drive the smaller inner square. In a further modification (Fig. 10) the larger square is omitted; rotation of the wheel 1 displaces a sector 47 which serves instead. The shape of the wheel 1 also differs (Figs. 7, 11, not shown) and the lower pole 16 of the magnet may be replaced by side plates embracing the wheel (Figs. 11, 12, not shown).

Abstract: 1284103 Loading and unloading bales SPERRY RAND CORP 25 Aug 1969 [26 Aug 1968 29 May 1969] 42215/69 Heading B8E A bale wagon includes a load bed 250 provided with a rolling rack 300 movable toward and away from a transfer table 200 by hydraulic means. Alternatively these means may be used to control the movement of tiers of bales deposited on the rack 300. The rack comprises two spaced-apart forks 302 carried for movement along a platform 254 of the load bed 250 by trolley assemblies 310. The rack is connected by a cable 342 to a double-acting hydraulic cylinder 528 and when bales are loaded on to the bed 250 from the table 200, the rack is shifted rearwardly but is braked by fluid from the cylinder 528 passing through a low pressure relief valve 552. When bales are to be unloaded, a manual control lever 546 is shifted from its neutral position to position (1) in Fig. 3 (not shown) to cause operation of the cylinder 528 such that the rack 300 is advanced and the forward-most tier of bales C falls on to the table 200 at position D. An hydraulic valve 552 ensures that fluid flows to either the cylinder 528 or to a motor (560), Fig. 3, which drives an endless discharge conveyer 350, but not to both. A latch 432 acting on the valve 552 ensures that the rack 300 cannot be advanced except when bale hooks 362, which control all but the lowermost layer of bales on the table 200, are retracted.

A mounting for one or more cylindrically - bodied semi - conductor devices comprises a block having for the or each semi-conductor device a bore lined by a resiliently-compressible sleeve which is corrugated longitudinally of the bore and whereof the minimum diameter is slightly less than the bottom limit of the semi-conductor device to be mounted in the bore. The semiconductor device (e.g. a transistor, diode or rectifier) is a semi-conductor housed in a cylindrically-bodied cover can. On introduction of the semi-conductor device into the bore the sleeve is deformed and squeezed between the bore wall and the semi-conductor device, whereby the semi-conductor device is resiliently held in the bore. One example of mounting is a block 27 (Fig. 7) having bores 28, each locating a corrugated sleeve 32. Countersunk bolt holes 29 permit securing of block 27 to a chassis. Fins 31 assist dissipation of heat. Each sleeve 32 is of corrugated aluminium sheet and is inserted into its bore under slight compression so that when released it presses against the bore wall. One end of the sleeve 32 has a conical formation 34 (Fig. 9) made by a nosed tool (Fig. 10). A step 111 resists the thrust of swaging and of entering of the semiconductor device. A block 20 (Fig. 1) has two cylindrical bores 21 which are of reduced diameter at end 22. Countersunk bolt holes 23 are at right angles to the axes of the bores 21. Other blocks are described for mounting four and six semi-conductor devices (Figs. 3, 4 and 5, 6, not shown). Cooling fins are not provided. A block 36 (Fig. 11) having cooling fins 38 is provided with bolt holes (not shown), one between each end of block 36 and the adjacent bore 37, the axes of the bolt holes being at right angles to those of the bores, with one emerging between one pair of adjacent fins and the other emerging between the other pair of adjacent fins.
