Title: Improvements in electric transformers
IPC: B61L1/18
Filed: 1926-07-31
Abstract: 278,831. Tinsley, H., and Gall, D. C. July 31, 1926. Systems depending on static transformers.-A transformer, particularly suitable for use in electric railway signalling systems, is provided with two primary windings and has associated with one winding means, such as a condenser, adapted to produce a time displacement between the primary currents, produced from a single phase supply, so that a decrease of impedance in the secondary circuit causes a decrease in the current or power output in that circuit. Fig. 3 shows the transformer applied to a railway signalling system in which a relay 6 is connected through the track rails 4, in sections separated by insulated joints 5, in series with the secondary winding of the transformer 7 having two primary windings connected in parallel with the supply mains 8, one winding having a condenser or phase changing device 3. When the track section is unoccupied the relay 6 is supplied with actuating current to maintain a signal, crontrolled by the relay, in a safety position. The presence of a train in the section decreases the impedance so that the current output in the secondary or track circuit is decreased due to the action of the transformer thus ensuring the deenergization of the relay and consequent operation of a danger signal. The device may be formed so that the phase changing device con. stitutes an integral part of the structure or by assembling and connecting a pair of transformers and a condenser or a condenser and transformer having a divided or tapped primary winding. The transformer may be used with two element or polyphase track relays.

Title: Improvements in continuously variable friction gearing
IPC: F16H61/662
Filed: 1931-07-04
Abstract: 377,402. Variable-speed gearing. TONDEUR, R., 25, Denbigh Terrace, Bayswater, London. July 4, 1931, [April 10, 1928, date given under Sect. 15 of the Acts, being that of 306,752, [Class 80 (ii), Gearing, Variable-speed &c.]], No. 19362. [Class 80 (ii).] Variable-speed friction gearing suitable for motor-vehicles comprising a friction driven member k movable transversely with respect to a driving-member c is operated automatically in accordance with the speed, or with the torque, or in accordance with both jointly. The member c turns with a shaft a fixed in position and has a conical gear face c<1> which is thrust out axially so as to draw the member k inwards and control the speed by a centrifugal governor such as that described in Specification 379,807, [Group XXVI]. The surface. c<1> is box-shaped and has a feathered connection at b<1> with a rigid cylindrical box b within which is a loose cam ring f turned against springs d by a pivoted centrifugal weight g. The driven member k is supported on a short shaft i, which moves parallel to itself being carried upon an arm j pivoted at j<1>, a universally jointed shaft h transmitting the drive. A toggle link m comprising a spring in compression tends to hold the arm j displaced eccentrically, and the rearward wedging thrust on the member k is supported by a buffer link n. The torque-responsive control is a balance between the axial thrust of cone c<1> pulling member k inwards and the reaction of the drive by the same cone, tending to thrust the same member outwards. An imposed manual control is effected by applying axial thrust to the other end of the buffer link n, and a handlever for doing this is described. When this lever is withdrawn to disconnect the drive, it may be coupled to a control for operating a suitable auxiliary reversing-gear. In the arrangement shown, the member k has two friction surfaces k<1>, k<3> of different coefficients, as described in Specification 374,655.
