Title: Improvements in or relating to Variable Speed Transmission Gear.
IPC: F16H13/10
Filed: 1918-12-18
Abstract: 136,640. Palladium Autocars, Ltd., and Baxter, D. J. W. Dec. 18, 1918. Variable-speed gearing, of the kind in which a driving disk such as A<1> is pressed against a roller A<2> with a force which increases as the roller is moved towards the centre of the disk, comprises a main spring D and an auxiliary spring D' for the regulation of the force. These springs act through a lever C turning about a fixed pivot C', this lever being in the form of parallel bars engaging a groove in a sleeve A<1x> secured to the disk A<1> A change-speed lever A<3>, which is connected by link-work to the roller A<2> to operate it, carries a cam A<4> which acts through a lever A<5> on the spring D<1> so as to vary its tension. In the application to a motor-vehicle, pedal-levers E<2>, F<2> are connected to the lever C on opposite sides of its pivot, so as to be able to increase the frictional pressure positively, or to disconnect the drive, respectively.

[Classes 40 (iii) and 40 (v)] In a system in which programmes on different carrier frequencies are distributed over a power network &c., each amplifier output circuit comprises, in addition to a matching transformer 6 or matching network, circuits such as 12, 13 designed to reject the frequencies of the other channels and so prevent cross-modulation in the amplifier, a band-pass filter 7-10, the reactances of which are in part composed of the effective reactances of the rejector circuits, the leakage inductance of transformer 5 and the inductance of the network, and preferably a low-pass filter 4 designed to prevent harmonics generated in the amplifier from reaching the line. In certain cases the whole of the inductive reactance of the band-pass filter may be provided by the transformer, the rejector circuits and the feeders. The rejector circuits are preferably of the form shown in Fig. 2, which is more suitable for rejecting a band of frequencies than a simple tuned circuit. Transformer 5 is designed to give bad regulation and its ratio is somewhat less than that required for optimum impedance matching. The bandpass filter may be wholly or in part on the amplifier side of the transformer and is preferably grounded at a nodal point for, e.g. the carrier frequency through condenser 11. The feeders to the network may be single core cables in which case the coupling condensers 25-28 are at the network ends of the feeders. Instead of separate feeders a low-impedance common feeder may be used. Specification 325,833, [Class 40 (v)], is referred to.

Title: Protective arrangement for booster transformers

Filed: 1934-08-02
Abstract: 442,150. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and MATHEWS, P., 7, Elsee Road, Rugby. Aug. 2, 1934, No. 22551. [Class 38 (v)] A booster transformer having its primary 2 in a shunt to the main circuit 1 and its secondary 3 connected to a transformer with a winding 5 in the main circuit 1, is protected by means of an overload relay 10 that is rendered immune from operation by throughshort circuit in the main 1 due to 4, 5 acting as a current transformer and producing current in the primary 2. The secondary 12 of a currenttransformer in the main 1 energizes a winding 11, which oppositely magnetizes two core portions 7, 8 of a current transformer 6 in the shunt circuit, both of which portions are linked by the winding 9 feeding the relay 10. The effect is that the iron of the cores is saturated on through-fault conditions in the main, but no resultant voltage is induced in 9. The resulting reduction in permeability due to saturation, however, demands more ampere-turns in the primary to produce a superposed flux required to give an operating voltage in 9, and by proper design the said ampere-turns may be made to increase with increasing fault current in 1 at a greater rate than the current injected into 2 by the transformer 4, 5. The Provisional Specification refers to Specification 303,221, [Class 38 (v)].
