Filed: 1968-03-26
Abstract: 1,213,495. Control of D.C. motors. STEINBOOK G.m.b.H. 26 April, 1968, No. 14512/68. Headings H2A and H2J. An electric motor has additional field windings provided in series with the main field winding to cause overexcitation during starting. As shown, motor M has a main series field winding connected between terminals EF1 and two additional field windings connected between terminals F1, F2; F2, F3 respectively. On starting relay 7 or 8 is closed, depending on the direction of rotation selected at drum control switch 3, supplying power from battery 1 to armature M and all field windings in series. During acceleration switch 3 is rotated further to close relay 9 which short circuits the windings between terminals F2, F3 and further rotation of the switch operates relay 10 to short circuit the winding between F1, F2. The additional windings may consist of a plurality of parallel branches of fine wire so that accommodation on the poles is facilitated. A motor with two separate armature windings each with its own commutator and associated field winding system is described. The motors, combined in a single housing, may be connected in series or parallel.

Abstract: 235,234. Grupe, W. F. June 9, 1924, [Convention date]. Moulding cork.-In calendering and pressing machines in which the rolls or pressure plate are intended to operate when heated by internally-applied heat, the rolls or pressure plate are surfaced with a padding made from substantially flat cork particles which are moulded under pressure and heat in excess of the working pressure and temperature of the finished articles, the natural resin of the cork causing the particles to be interbonded with one another. The particles are arranged to be substantially parallel to one another in planes at right angles to the axis of the roller or at right angles to the working surface of the bed. As shown, the cover 14, Fig. 3, for a roller 10 is moulded in one or more longitudinal parts, having internal ribs 15 entering grooves 16 in the roller, intervening air spaces 17 being provided. In a modification, the cover is corrugated internally and grooved externally. The cover may be a plain sleeve having a slot for a keyway. The cork particles are fed between the sections of a. two-part mould by a tamping tool. The filled mould is then raised to a sufficiently high temperature to cause the exudation of the natural resin which, on cooling, serves as a binding-medium. The Specification as open to inspection under Sect. 91 (3) (a) describes also the addition of resins of higher melting point than cork resin to the cork particles. This subject-matter does not appear in the Specification as accepted.

Title: Electric discharge device having an auxiliary electrode, particularly for the production of short-duration arcs
IPC: G01R31/14
Filed: 1946-05-20
Abstract: 630,677. Rectifying ; switching systems. ETABLISSEMENTS MERLIN & GERIN. May 20, 1946, No. 15155. Convention date, May 5, 1943. [Classes 38 (ii) and 38 (iv)] [Also in Groups XXXVI and XL (a)] A discharge device comprises a main electrode 1, Fig. 1, an auxiliary electrode 2 housed in a chamber 3 so that the auxiliary arc strikes between the electrode 2 and the wall of the orifice 4 which serves as a second auxiliary electrode, and the auxiliary arc is confined within the chamber 3 at all times, and ignition of the main arc is effected by a jet of ionized gas passing through the orifice 4. In one circuit arrangement Fig. 7, it is desired to close circuit 23, 1, 1<1>, 24, at a predetermined point in the voltage wave supplied by generator 23. This is achieved by supplying part of the generator output to ignition electrode 2 via variable phase shifter 27 and transformer 25. To prevent premature ignition by the voltage surge produced when switch 28 is closed, a resistance 26 is provided, and the intensity of the auxiliary discharge may be regulated by an impedance 29. The ignition discharge must not last longer than a quarter period ; it may be extinguished by gases escaping from orifice 4, by an auxiliary arc-gap, by a resistance whose resistivity varies with the applied voltage, or by an automatic switch. The precision of the ignition is increased by using a sharp voltage wave, e.g. produced by a resistance in series with a transformer or an inductance with a saturated magnetic core. Switch 30 allows the device to be short-circuited when desired. In a modification, Fig. 8, the phase displacement is obtained by angular displacement of stator 32 of alternator 31 which may be mechanically coupled to generator 23 if the latter is a rotary machine. If the generator 23 is the secondary circuit of a stationary transformer, the alternator 31 is controlled by a synchronous motor. In another modification, Fig. 9, the alternator 31 is replaced by a rotary arc-gap 36 which discharges condenser 37 at the required instants. If the devices of Figs. 7-9 are provided with means for the dielectric regeneration of the discharge gap then the devices can be used as rectifiers. The device of Fig. 9 can be used as a monophase rectifier without further modification, and the devices of Figs. 7 and 8 can be so used provided that the ignition circuit is polarised by inserting a source of continuous E.M.F. or a rectifier. Polyphase rectification is possible by using a number of discharge devices equal to the number of phases to be rectified.

Fastenings for doors; coin action, weight.-In a coin-freed lock for lavatory doors the coin inserted through a slot a, by its momentum and weight rocks a cradle b which lifts a vertical locking-piece c from the bolt d operated by the outside handle. The coin falls through the slotted bolt d and rests on a lower sliding piece e shouldered into the bolt d. The coin falls down to a money-box when the piece e is operated by the inside handle to draw back the bolt, the cradle b being acted on by a lever f to lift the locking piece c. To prevent the bolt d from being locked by the piece c when the door is open and the coin has dropped into the cash -box the lower end of a strut g pivoted to the piece e engages a notch in the lock casing and prevents the bolt from being projected fully. When the bolt is moved back by the closing of the door, it engages the upper end of the strut and frees it from the notch so that the bolt can move forward fully and be locked by the piece c. Coin-slit closing-devices; indicators.-To prevent the insertion of a coin if the locking-piece c is bound in position by pressure on the outside handle, a stud on the bolt d engages an incline on a rocking lever h to move its upper end across the slot a. The insertion of a second coin is prevented by a sliding claw i adapted to be moved and held under the coin slot by the locking-piece c when this is lifted. An indicator-plate k, Fig. 3, is moved against the action of a spring to " engaged position by pressing down a thumbpiece l. In this position it covers the coin-slot a on the outside.
