Title: Animated toy
IPC: A63H29/00
Filed: 1970-04-09
Abstract: 1,269,752. Dancing toy. MATTEL Inc. 9 April, 1970 [2 June, 1969], No. 16938/70. Heading A6S. A dancing toy, e.g. a ballerina, is operated by means of an electric motor 215 on whose output shaft is a pinion 217 driving a gear 218 which rotates freely about an idler shaft 212. Gear 218 in turn drives a gear 220 which is free to rotate about a shaft 224, and this gear drives a gear 235 which rotates freely about idler shaft 212, and gear 235 drives a gear 224 which is keyed to shaft 222. At the further end of shaft 222 is keyed a bevel gear 226 driving another bevel gear 228 which is keyed to a shaft 230, at the ends of which are cranks 231 and 232 by which means the legs are enabled to perform a stopping motion. The gear 235 is maintained in mesh with gear 224 by means of a spring 236 and these gears may be disconnected by depressing a control rod 210 at the foot of the control rod is a clutch comprising tabs 244 which locate in a slot 242 on gear 235, thus when the control rod 210 is raised then it is not connected to gear 235, but because of spring 236 the drive causes a stepping motion of the legs. However, when control rod 210 is depressed, it is connected to gear 235, but gear 235 is also depressed so that it is disconnected from the drive to the legs, thus the control rod and the body of the doll may rotate relative to one-another, and by holding the end of the rod protruding through the doll's head, the doll may pirouette about the axis of rod 210. The control rod is also associated with a switch mechanism which switches the motor on when the rod is fully up or fully down and off when in an intermediate position, and also enables reversal of the direction of drive. This mechanism is illustrated in Figs. 4 and 5 (not shown). Also, while the doll is pirouetting, by means of a mechanism illustrated in Figs. 4, 6, 7, 8, 9 (not shown) and comprising essentially a cam mechanism causing a spring to be tensioned and released, the dolls head is oscillated relative to its body.

Abstract: 940,825. Control of A.C. motors. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 7, 1962 [May 10, 1961], No. 17479/62. Heading H2J. Relates to the remote control of a reversible three-phase motor M which, in given extreme positions, feeds back a signal to the control station, which signal indicates the state of the motor windings. The motor is arranged at a distance from contactors R, L, and is provided with limit switches E1, E2, and checking contacts TC1, TC2. When contact E1 is closed, the voltage across the right-hand motor winding is fed through capacitor C to wire cd and thence to the primary of transformer T1. The corresponding mains phase voltage is fed through contact a to the primary winding of transformer T2, the secondary windings of the transformers being connected to phase detector FD which supplies, when there is phase-equality, a control current through contact C to energize signal relay RS. This disconnects the motor, a checking-current being passed through the central and right-hand motor windings, and through the holding winding of relay RS. With the other sense of rotation, the checking- current passes through the central and lefthand motor windings. In another arrangement, all the windings of the motor are checked at each end-position, Fig. 1a (not shown). In a further embodiment, the number of checking conductors is reduced by connecting a power transformer between the motor and the mains, the primary winding of the transformer T1 being fed from this transformer. The checking- current passes through the primary winding of transformer T1, the secondary windings of the power transformer, the motor windings, and the secondary winding of another transformer to earth, Fig. 2 (not shown). The check may be carried out by using alternating-current.

Abstract: 912,728. Making expanded metal. MENTIS, A. May 15, 1961 [July 20, 1960], No. 17541/61. Class 83 (4). An automatic expanded metal press comprises a rigid frame having a fixed cutter therein, a single cutter beam having means for the rigid attachment of a complementary cutter thereto, said beam being mounted and driven to reciprocate both vertically and laterally, and means for feeding sheet metal to the fixed cutter. The cutter beam reciprocates in a frame 1 which carries a fixed cutter-bar 4. The beam 2 slides between flat side bearings 8 which also allow lateral movement. A sawtoothed cutter bar 6 is mounted on the beam which is reciprocated by two connecting rods 10 which have spherical ball-bearings 15 mounted on a driving shaft 13, and spherical joints 16 at the small ends, which include screws 17 by which the downward travel of the beam can be adjusted. The beam is partially counterbalanced by two springs 18 attached to the beam at their centres and having a roller 19 at each end which run on the frame 1 as the springs flatten. After each shearing stroke the beam moves laterally so that each row of cuts is displaced from the previous row and this is achieved by an arm 20, the end 21 of which is pivoted to the beam and the other end of which terminates in a strap 23 fitting round a variablethrow eccentric 24. The eccentric is moved intermittently by a rack 29 and pinion 30 operated by a cam 32. The cam is mounted on a shaft 34 driven at half the speed of the mainshaft 13. Strip-feeding means.-The strip is fed by a pair of horizontally reciprocating clamping jaws 35 mounted on spindles 36, spring-loaded to a rearward position determined by stops 37, which thus control the length of feed stroke. The jaws are moved forward by a pivoted lever 39 which is acted on by a cam 42 mounted on the mainshaft 13. The clamping jaws 35 each consist of a lower jaw 43 and a movable upper jaw in the form of a piston 44 backed by a diaphragm 45 which communicates with an hydraulic cylinder 46. The cylinder has a piston 47 operated by a cam 48 mounted on the mainshaft 13 and arranged so that the jaws clamp on the strip as the clamping jaws are moved forward and while the strip is held stationary during cutting, and then open as the jaws retract.
