Title: Improvements in short-circuited windings for dynamo electric machines
IPC: H02K17/16
Filed: 1942-08-26
Abstract: 560,034. Induction motors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, and ARNEMO, H. Aug. 26, 1942, No. 12003. [Class 35] In a short-circuited winding for a dynamo electric machine, the winding bars 4 are provided with radial slots at their ends, the two parts of the slotted ends being joined to the short-circuiting rings 3 by soldering or brazing. The connection between the bar and the rings is thus elastic to allow movement due to thermal expansion of the rings without strain. The bars 4 may be free in the armature slots except at points x where the armature slot is restricted in width to hold them. The bars may thus bend freely. This is also effected in an alternative construction where the bars are only held at the centre instead of towards the ends. In machines in which the centrifugal effect on the bars is low, the bars 4 need not be soldered, brazed or otherwise secured but merely rest in slots in the rings 3. An elastic material may be arranged in the slot in ring 3 below the bar 4.

Title: Improvements in and relating to radio-frequency inductors or transformers
IPC: H01F17/00
Filed: 1946-04-22
Abstract: 611,132. Inductances; transformers. HOLZER, R. C. DE. April 22, 1946, No. 12177. [Class 38 (ii)] A substantially cylindrical former for an inductance or transformer is arranged so that one or both ends project beyond a coil or coils mounted on the former, and each projecting end portion is flattened so that the opposing walls are brought into contact and are then secured together by riveting, gluing or welding. Fig. 1 shows a radio frequency transformer comprising coils 4 and 5 mounted on a thin cylindrical former 3 made of impregnated paper or a thermoplastic or thermosetting material, and enclosing a fixed iron dust core 1 and a movable core 2 of similar material mounted on screw-threaded rod 8. Both ends of the former are flattened and the contacting portions secured together by rivets 6 which are connected to the ends of the adjacent coils 4, 5 and may also secure in position tabs 7 providing connector terminals. When the former is made of comparatively soft material such as paper or a thermoplastic, the flattening of the material directly adjacent to the screwed rod 8 produces a female screw-thread which engages the rod. Alternatively, if the former is made of relatively hard material, two pieces of softer material such as cardboard may be inserted between the screw 8 and the opposing flattened walls of the former. In a modification, the former is made in two channel-like pieces of semicircular cross-section with flattened ends, and these pieces, which are made of a thermosetting or ceramic material are assembled together and the flattened ends secured together by rivets, The rivets may also serve to secure metal angle pieces which provide feet for mounting the device. Alternatively, the device may be mounted longitudinally within a correspondingly shaped aperture in a frame comprising a sheet of insulating material provided with terminal tabs which may be connected to the ends of the coils by conductors which may consist of metal sprayed on to the frame. The frame may be subsequently located within a metal screening-can formed in two longitudinal sections each of triangular cross-section secured overlappingly on opposite sides of the frame. In a modification, one end only of the insulating coil former is flattened and connected to terminal tabs, the opposite end being provided with a metal bush held in position by an outer clamping ring and screw-threaded internally to receive a screw which provides adjustment of at least part of a metal dust core.

Title: Improvements in or relating to the production of methanol and other oxygenated organic compounds
IPC: C07C31/04
Filed: 1926-05-12
Abstract: 275,345. Synthetic Ammonia & Nitrates, Ltd., and Smith, H. G. May 12,1926. Methanol, higher alcohols, and other oxygenated organic compounds are produced by interaction of carbon oxides and hydrogen at elevated temperature and pressure in the presence of a catalyst comprising a basic zinc chromate of the composition 4ZnO.CrO3. This catalyst, which becomes reduced during the operation or may be reduced beforehand, effects the synthesis at low temperatures (300-400‹ C.), and is not poisoned by sulphur, though volatile compounds of iron, nickel and cobalt should be excluded. The basic zinc chromate is made by adding a slight excess of chromic acid to an aqueous suspension of zinc oxide or hydroxide, or by double decomposition of say zinc sulphate with sodium chromate. Except for the production of methanol, soluble alkali salts may be present in the material. Comparative experiments using a catalyst of varying composition of zinc and chromium oxides under standard reaction conditions are described. Specification 227,147 is referred to.
