Title: Electric circuit breaker arrangement
IPC: H01H73/26
Filed: 1974-09-20
Abstract: 1473203 Circuit breakers OTTERMILL Ltd 20 Sept 1974 41035/74 Heading H1N Simultaneous tripping of adjacent circuit breakers arranged as a multipole circuit breaker when an overload current causes one to trip is effected by interposing between each adjacent pair of circuit breakers a device 44 that has an operating portion 46 extending laterally on both sides to engage the tripping mechanism of each breaker. The device 44 is within a frame 39 that has holes 42 through which pass screws or rivets holding the breakers together. The device 44 pivots on stub axles 45 that extend into holes 47 in the adjacent circuit breaker casing, or may be pivoted to frame 39 by a resilient member. Portions 46 extend through slots 48 in the adjacent circuit breaker walls. Portions 46 may have axial sockets 50 and pegs 49 to engage with corresponding portions of similar devices when more than two circuit breakers are adjacent. Spring 51 (or a resilient tail of the device) biases the device to its non-tripping position. The device is described in conjunction with circuit breakers each having an overcentre spring action 2, 4, and a tripping lever 14 engaged in a hole 16 of latch 17. Current passes from moving contact 5 via flexible lead 10 to coil 20 (with core 21 mounted on bimetallic strip 22) through which current flows to terminal 12. Persistent overload current heats bimetallic strip 22, which bends. Crank 24, 25 moves latch 17 to release lever 14. Overload currents also attract armature 27, pivotally mounted against the bimetallic member by portion 28 from which it is insulated by strip 29. The alternating field attracts and releases the armature rapidly so that it strikes repeatedly the end 32 of a slot 30 in lever 17 in which it is engaged, again to release the latch 14. Latch 14 rotates clockwise and moves portion 46 downwardly (as shown in Fig. 2) this motion being transmitted to adjacent like circuit breakers so that in them the corresponding latches 17 are also moved to release the corresponding levers 14.

Abstract: 1,131,322. Table tennis balls. DUNLOP CO. Ltd. 6 Oct., 1965 [14 Oct., 1964], No. 41827/64. Heading A6D. [Also in Division B5] Apparatus 39 for welding two shaped sheets 10, 38 of thermoplastic material together to form a table-tennis ball comprises a pair of electrodes each comprising an open-end cylinder 42 having an internal diameter at the open end substantially equal to the external diameter of a table-tennis ball and the cylinders 42 being arranged so that the open ends thereof are directly opposed, means to connect the electrodes to a source 46 of high frequency alternating electric current, and means to reduce the separation of the electrodes 42 during passage of the current therebetween. The sheets 10, 38 may be previously shaped by the method described in Specification 1,131,361. The apparatus 39 comprises a number of rod-like cylinders 42 on parts 40, 41 and which are shaped to conform to hemispherical projections 43 on the sheets 10, 38. The cylinders 42 are mounted to form electrodes on base plates 44, 45 which are connectable to the source 46. The periphery of each cylinder 42 is chamfered so as to produce a line of high concentration of the alternating current and the end surfaces 48, 49, Figs. 7 and 8 (both not shown), of an opposed pair of cylinders 42 are shaped to form a V-section gap 50 the angle of which is from ¢‹-7‹, preferably 3‹. The upper part 40 is mounted on a bar 51 slidable in a cylinder 52 and when the source 46 is connected, the bar 51 is moved, as the sheets 10, 38 are softened, to bring the part 40 closer to the part 41 so that only a very fine gap remains between opposed cylinders 42. This movement forces some of the thermoplastic material into the interior of the ball to form a reinforcing bead 5. Fig. 8 (not shown). After welding, the balls are removed from the surrounding excess sheet material. In modification (not shown), the electrodes may be hollow cylindrical projections with or without a shaped core of insulating material. The apparatus may be maintained at a controlled elevated temperature to raise the temperature of the thermoplastic material prior to passage of the high frequency current but not sufficiently to cause the material to be deformable. Specified thermoplastic materials are polyvinyl chloride, terpolymers of acrylonitrile with butadiene and styrene, copolymers of diphenylolpropane and epichlorhydrin, polyamides, e.g. nylon, and polycarbonates.

Title: Improvements in or relating to change-speed hubs
IPC: B62M11/14
Filed: 1962-11-08
Abstract: 953,040. Change-speed gear; one-way acting brakes. FICHTEL & SACHS A.G. Nov. 8, 1962 [Nov. 11, 1961], No. 42305/62. Headings F2D and F2E. Ratio selection in a change-speed planetary hub for bicycles &c. is effected by backpedalling so that an input member 1, Fig. 1, formed with cam grooves 37, 38, 39, Fig. 3, turns relatively to a selector sleeve 4, itself carrying a spring-biased cam follower 5 engaging the grooves and restrained from reverse rotation by a one-way detent 3, thus sliding the selector sleeve and a ratio establishing clutch dog 8 in the input member, to engage the clutch dog with various parts of a fixed sun gear-planet pinions-ring gear train 23, 24, 14 driving selectively through two sets of ratchets 16, 19 to a surrounding hub shell 26. In the position shown, drive passes from a sprocket 27 fast with the input member 1 to the clutch dog 8, received in axial slots 60 in the input member, and thence to pins 34 journalling the planet pinions 24, a step-up drive being transmitted to the ring gear 14 and through the ratchet 19 to the hub shell 26. The cam follower 5 engages the end 40 of the ring cam groove 37. To establish the second ratio (direct drive), the sprocket 27 is momentarily back-pedalled. The follower 5 slides through the transverse groove 41, sliding the selector 4 rightwards of Fig. 1 against the bias of a spring 6, to disengage the clutch dog 8 from the planet pins 34 and instead engage it with the ring gear 14. When forward pedalling is resumed, the follower 5 slides to the end 43 of the groove 38. To establish third ratio, the sprocket 27 is again back-pedalled, the follower 5 slides along a transverse groove 42 into the cam groove 39, sliding the selector 4 further rightwards against the bias of the spring 6, engaging the clutch dog 8 with the tails of the ratchet pawls 19 to hold them disengaged. The step-down drive is then obtained through the ring gear 14, the planet pinions 24, the planet carrier 13 and ratchet pawls 16, on a back-pedal brake member 17, to the hub 26. On initiation of forward pedalling, the cam follower 5 moves to the end 44 of the cam groove 39. To initiate a downshift, the input sprocket 27 is again back-pedalled. The follower 5 moves to the opposite end of the groove 39, slides up a cammed slope 45 and out of the groove, and the spring 6 forces the selector 4 &c. leftwards to establish direct drive. The follower 5 enters a short extension of the groove 38 blocked at 53. On again backpedalling, the follower 5 slides up a cammed slope 46 out of the groove 38, and the spring 6 again slides the clutch dog 8 &c. leftwards, to establish the step-up ratio, the follower falling once more into the groove 37. The sequence of ratio shift may then be repeated. The one-way detent between the fixed axle 25 and the selector sleeve 4 comprises claws 3, Fig. 2, in a thrust block 2, biased radially by compression springs 47 to engage ratchet teeth 28 in the sleeve, the thrust block &c. sliding axially with the selector sleeve and the claws &c. projecting through slots in the axle.
