J., University College, Dublin. Feb. 12, 1932, Nos. 4260 and 29743. [Class 106 (ii).] A specimen of material is subjected to a fatigue test by causing it to vibrate in an electric field through the agency of an electric current passing through it. In the apparatus shown in Fig. 2, the current is regulated by the movements of the specimen 2, which is suspended by a pair of current-carrying torsion wires 12, the magnetic field being that of an electromagnet 15. Light from a lamp 16 falling upon a photo-electric cell 18 is periodically occulted by the specimen 2 passing through a focus of the optical system 17, 17 directing the light on the cell 18, the periodic current from which is passed into an amplifier 19 connected to a step-down transformer 21 supplying from its low-voltage side the operating current through the specimen. In a modified circuit the amplifier 19 is connected to a motorgenerator the output from which is fed to a transformer for supplying the current to the specimen. In another modified circuit the low-voltage side of a transformer, connected on the high-voltage side to an amplifier as in the apparatus of Fig. 2, is connected to the grids of a pair of thyratron valves, the output from the valves being fed to the specimen through a condenser or transformer. In another construction shown in Fig. 5, the specimen 2 is carried in wire loops 34, connected through terminals 35a, 36a to the in-put of a step-up transformer 40 and through terminals 35b, 36b to the output of a step-down transformer 44, these two transformers being connected through valves 45, 46 to an intermediate tuned transformer 47.

Filed: 1933-02-15
Abstract: 398,728. Vehicle brakes. LANCIA & CO. FABBRICA AUTOMOBILI TORINO SOC. ANON., 99, Via Monginevro, Turin, Italy. Feb. 15, 1933, No. 4677. Convention date, Feb. 15, 1932. [Class 103 (i).] An hydraulic vehicle brake is operated by a hand pump, and a member transmitting the pressure to the brakes is adapted to be held by a mechanical stop such as a pawl, which prevents release of the brakes. The pump comprises a small and a large piston 10, 11 operated by a hand-lever 5 adapted to oscillate on a shaft 6 and arranged so that the compression stroke of the large piston takes place in the direction of displacement of the lever in which the operator's arm can exert the larger effort. Each pump is supplied with liquid from the casing 1 of the apparatus and has a suction chamber 16 and compression chamber 19 controlled by valves 17, 20. The compression chambers 19 are connected to a cylinder 25 containing a,piston 26 connected to a sector 28 fixed on the shaft 6 connected to the brakes. When liquid is pumped below the piston 26 to apply the brakes, a pawl 31 co-operates with teeth 30 on the quadrant 28 and maintains the brakes applied. To release the brakes a member 44 slidable on the lever 5 is operated to engage by means of a tooth 40, the arcuate part 34 of a lever 33 fixed to the pawl which is thus disengaged. Further movement of the member 44 moves a member 36 to raise the stem 38 of a valve which releases the pressure from the cylinder 25 into the casing 1.

Filed: 1952-02-22
Abstract: 696,743. Transformers; supply systems for welding arcs. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 22, 1952 [Feb. 23, 1951], No. 4759/52. Classes 38 (ii) and 38 (iv). [Also in Group XXXVI] A transformer supplying an arc welding load comprises primary and secondary windings 3, 4 on a core 7 and has two auxiliary windings 5, 6 associated with the primary and secondary windings respectively, and so connected that they generate fluxes in opposition. Upon energization of the transformer, relay contacts 26 are closed to connect resistance 27 across the series-connected auxiliary windings, a circulating current then flowing through the auxiliary windings and resistance 27, whereby the leakage flux of the transformer is reduced and the output current increased for a time depending on the delay setting of relay 25. At the end of the set time owing to the fall in output volts of the transformer upon load passing, contacts 26 open and the output current falls. The load may be drawn from terminals 17, 18 or 17, 19, the auxiliary windings being respectively independent of or in series with the secondary winding 4, the circulating current in the latter case flowing through the auxiliary windings in opposition to the load current which is in effect reduced in these windings. For energizing the relay, one of switches 29, or 30, must be closed, and special couplings whereby the appropriate switch is closed upon connecting the load to terminal 18, or 19, are described (see Group XXXVI). The primary winding 3 and auxiliary winding 5 may be moved together by rotation of handle 13 to vary the transformation ratio, which ratio is varied still further by the auxiliary windings, as described in Specification 551,709. The auxiliary windings may be connected in series with the primary winding 3, Fig. 3 (not shown).

[Class 40 (ii)] A phonograph apparatus, in which the engagement and disengagement of the pick-up with the record is automatically effected by the insertion and withdrawal of a drawer, consists of a casing 1, Fig. 1, carrying the pick-up arm 3 and support, and a drawer 2 carrying the turntable and a cam 21, Fig. 7, which, during withdrawal and re-insertion of the drawer 2, effects both lifting of the pick-up arm 3 and its return to the starting position. When the drawer 2 is withdrawn, the lift rod 8, Fig. 4, rides up the cam slope 23 and lifts the pick-up arm 3 by means of the arm 9 and associated finger 10. Furthermore, during the opening and shutting operation of the drawer 2, the pick-up arm 3 is returned to the correct starting position by the engagement of the pin 20, Fig. 4, on the lever 19 with the cam surfaces 41 and 42, Fig. 7, and spring-loaded guide members 30 and 29. During this operation the current to the motor is interrupted by the breaking of a switch operated by a cam 13, Fig. 1. Adjustment for two sizes of record is effected by rotation of an eccentric disc 35 which moves the cam 21 about the pin 33, Figs. 4 and 7. In an alternative arrangement, Figs. 9 and 10 (not shown) a revolving cam, fitted with a toothed wheel and driven by a rack fixed to the drawer 2 is used. In another arrangement, Fig. 12 (not shown), the motor is separated from the turntable, and frictional contact is effected only when the drawer 2 is closed. In this case, no provision is made for lifting the pick-up arm, but instead the turntable is lifted and lowered by engagement with a fixed cam in the casing 1. Adjustment is provided in each arrangement for two sizes of record.
