Title: Improvements in and relating to dynamo electric machines
IPC: H02K19/14
Filed: 1920-11-16
Abstract: 175,084. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 16, 1920. Alternating-current motors; field magnets, dampers on poles of.-A synchronous motor carries a double squirrel-cage winding on the rotor, to enable the machine to be started as an induction motor and also to prevent hunting by acting as a damper. The high-inductance squirrel-cage winding consists of a small number of bars 23 of large cross-section, a single bar being located in the middle of each pole-face. These bars are connected to end rings 24, and in order to reducethe resistance additional conductors 26 are placed under the pole tips and connected to the end rings. The high-resistance low-inductance winding consists of a greater number of smaller bars- 20, extending through the pole faces and connected to end rings 21. In the figures, four high-resistance bars are shown per pole, but a modification is described in which there are eight such bars per pole, and the conductors 26 are dispensed with, bars similar to the bars 23 being placed across the end rings in the spaces between each pair of poles.

Filed: 1926-12-21
Abstract: 263,802. Lorenz Akt.-Ges., C. Dec. 24, 1925, [Convention date]. Insulators.-In insulators of the suspension or chain type consisting of a number of single insulator units arranged in series for suspending electric conductors carrying high voltage on transmission masts, wireless antenna structures &c., the capacity between the individual units divided by the number of insulators in series is at least equal to and is preferably greater than the sum of the capacities of the units relatively to the earth and to the high tension conductor, in order to provide a uniform distribution of voltage across the chain of insulators. In the embodiment of the invention shown in Fig. 3, a series of auxiliary capacities Cp are arranged in parallel with the natural capacities formed by the fittings f of the insulator units i. Alternatively the auxiliary capacities may be embodied in the construction of the insulators.

Title: Improvements in or relating to shaving brush cases
IPC: A45D27/04
Filed: 1947-12-08
Abstract: 636,508. Brush sheath. HOORN, J. F. VAN. Dec. 8, 1947, No. 32339. [Class 19] A case for a shaving brush is open at one end and is formed with a flared mouth into which the brush may be introduced, bristles leading, thus gradually reducing the overall diameter of the tuft of bristles and, at the other end, is formed with a chamber in which the tuft of bristles may expand after passing through the narrowest part of the flared mouth. The flared mouth may be presented by a liner secured in the open end of the case or the case may be of mouldable plastic material, the flared mouth being formed integrally therewith. The Figures show some of the various forms of brush case described. In Figs. 1 and 3 the case a is cylindrical exteriorly and closed at one end b which is preferably perforated as at h for ventilation purposes. The brush is introduced into the tapering mouth e and the tuft bristles then expands in the chamber f. In Fig. 6 the exterior of the case corresponds in shape with the interior and the chamber is globular. Fig. 7 shows the form in which a liner m having a tapering mouth e is secured in the open end of the case a. The stock of the shaving brush may be screw threaded or similarly formed, e.g. with a bayonet joint so that it may be secured in the case and when the brush is in use the case may be screwed on or otherwise secured to the brush to present a long handle, The brush stock may be of such diameter so as to abut against the inner wall of the flared mouth at its smallest part or the whole or part of the stock may be a push fit in the flared mouth.

A rotary vane pump or motor comprising a casing eccentrically mounting a rotor having vanes either guided for sliding movement or sliding pivotal movement, includes apertures located at the points of least and greatest distance between the casing bore and rotor which are interconnected by a pipe. In one embodiment, a casing 10, Fig. 1, having an inlet 11 and outlet 12 eccentrically mounts a rotor 13 having slidably guided vanes 16a, 16b, 16c. Apertures 18a, 18b interconnected by a pipe 19 are located respectively at the points of least and greatest distance between the rotor and the casing bore with the width B of the apertures less than the width D of the vanes. On rotation of the rotor in the direction of the arrow hydraulic fluid trapped, e.g., between the vanes 16a, 16b in the movement of the vane 16a from its chain-dotted position to the position where it masks the aperture 18a is expelled through the pipe 19 and reenters the casing between the vanes 16c, 16a to remove back pressure from the leading face of the vane 16a and to reduce noise and shocks, the fluid being discharged through the outlet 12. On the passage of the vane 16c past the aperture 18b with the aperture 18a still open, the fluid re-enters the casing between the vanes 16b, 16c and is added to that entering directly through the inlet 11. On the closure of the inlet 11 by the vane 16b and the passage of the vane 16a past the aperture 18a the fluid between the vanes 16b, 16c is expelled through the aperture 18b and flows through the line 19 and aperture 18a to the outlet 12. The number of vanes need not be limited to three. In another embodiment, the rotor includes five vanes (46a), (46b), (46c), (46d), (46e), Fig. 4 (not shown) mounted concentrically with the casing on a journal 45 are additionally guided in guides (43a), (43b), (43c), (43d), (43e) which are mounted for rotation in the rotor (43) which is disposed eccentric with respect to the casing.

[Class 18] [Also in Group X] Plates or sheets are joined to form a box, by forming pyramidal shapes at the corners of the sheets, assembing the shaped corners so that their apices substantially coincide, Fig. 3, and fixing the plates in position by means of bolts 2 carrying nuts 1 passing through the apices, Fig. 7, or by permanent fixing such as welding or riveting. The pyramidal shape may be obtained by cutting and bending along the dotted lines, Fig. 1, at the corners of the sheet. After bending the sheet will have flanges and a triangular corner portion OVU. Alternatively, pressings, castings or mouldings may be connected to the flanges of the plates to form the pyramidal cbrners. The flanges of adjacent plates are adapted to lie against each other and strips of felt or rubber may be inserted between them. The nut 1 may carry a washer shaped to grip the insides of the pyramidal corners.
