Title: Improvements relating to regulator machines for use with rotary transformers of the kind known as metadyne transformers
IPC: H02K47/16
Filed: 1938-02-09
Abstract: 510,887. Rotary transformers. TUSTIN, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 9, 1938, No. 4092. [Class 35] In a system wherein a metadyne transformer has a regulator winding RW, and a direct current regulator dynamo RD mechanically coupled with the metadyne is connected in series with the regulator winding across the supply, the regulator machine is compound wound with the series field winding in two sections A, B which are connected (1) in parallel and assist the shunt field winding during starting, (2) in series with each other one opposing and one assisting the shunt field winding when the metadyne is running light with its primary bushes disconnected or (3) in parallel with each other, both windings opposed, or assisting the shunt field winding according to whether the regulator machine is motoring or regenerating when the metadyne is on load. In condition (1) the regulator dynamo acts as a starting motor with high starting torque, and in condition (2) the regulator maintains the: transformer at the desired speed, the regulator winding being usually disconnected in both conditions. In normal running (3), the regulator winding is excited differentially by the supply voltage and the voltage of the regulator machine. The start1 ing connections are shown in Fig. 1 a limiting resistance r' being connected in series with the armature RD. For running unloaded, switch S<2> and S<3> are closed and switches S' and S' opened so that the winding sections A, B are in series opposites and the resistance r<1> is connected across the section A. In normal running switches S', S' and S' are closed and S<2> opened so that the winding sections A, B are in parallel and opposing the shunt winding with the resistance r' connected across them. In the case of a fourpole wire-wound regulator dynamo, the shunt winding is distributed on all four poles and the two sections of the series windings are on alternate pairs of adjacent poles to minimise inductance between the sections. An additional resistance may be included in the armature circuit at starting and another in the shunt field current during coasting. Specifications 417,517, 418,461, 420,979 and 424,082 are referred to.

Title: Improved method of and apparatus for the purification of low melting point alloys
IPC: C22B9/00
Filed: 1945-02-20
Abstract: 590,083. Refining alloys. FORD MOTOR CO., Ltd. Feb. 20, 1945, No. 4297. Convention date, June 16, 1943. [Class 82 (i)] Used low melting-point alloys of the Wood's metal type are purified by three steps : (1) settling said molten alloy to remove most of the impurities therefrom, (2) passing through an acid bath and (3) through a neutralizing bath. The molten alloy is introduced by a pipe 15 and valve 16 into a settling tank 14. The lighter impurities rise to the surface and form a slag, which may be drawn off by a pipe 19. The partly purified alloy 22, drawn off through the pipe 23, flows down the trough 26 in droplets 25, and over baffles 31 in an acid bath, such as hydrochloric acid of 20 per cent. strength by volume, in the tank 27. A sludge of the remaining impurities is precipitated, the alloy collecting in a sump 32 and flowing as droplets through a pipe 33 into a neutralizing bath 38, which may be a weak solution of sodium bicarbonate, from which it is withdrawn through a pipe 39 into a mould 13. Water jackets maintain the temperature of the tank 14 and the two baths above 180‹F. so that the alloy remains molten.
