Title: Reducing stray losses in a laminated rotor
Inventor: TURNER WILLIAM BRIAN
IPC: H02K1/24
Filed: 2007-07-11
Abstract: The rotor comprises a plurality of salient poles 14, 16 comprising a main pole body 18, 20 and a pole shoes extending from the body overlying the windings. At least one part of each pole shoe of pole 14 is recessed 40,44 in a circumferential direction with respect to another part of the same pole shoe 42,46, and the recessed part of a pole shoe is aligned with a non-recessed part of an opposing pole shoe 16. This can increase the apparent air gap between adjacent poles, which may allow magnetic flux leakage from one pole to another to be reduced, while still enabling the pole shoe to retain the windings and to distribute magnetic flux across the air gap between the rotor and stator. The laminations may be identically stamped and stacked rotated by 90{ to provide the required recesses. Amortisseur bars (fig 4) may be present and a castellation effect may be achieved (fig 3). Figs 5 and 6 show a coil wedging arrangement.

Title: Improvements in or relating to the manufacture of lower aliphatic esters
IPC: C07C69/24
Filed: 1954-04-07
Abstract: Esters, containing not more than six carbon atoms, are produced by continuously introducing a monobasic aliphatic acid and a monohydric aliphatic alcohol into a catalytic esterification bath containing at least 20 per cent by weight of an auxiliary organic liquid whose boiling point is both higher than that of said ester and not less than 120 DEG  C., which is stable under the esterification conditions, which is homogeneously miscible with the remainder of the bath and which does not form from the remainder of the bath an azeotropic mixture having a boiling point lower than that of the azeotropic mixture of water with the said ester.  Suitable auxiliary liquids include esters, ethers, e.g. butyl ether, ketones, e.g. dipropyl ketone, and hydrocarbons, e.g. xylene.  An ester of the aliphatic acid to be esterified, with an alcohol of higher boiling point, is suitable.  Preferably the alcohol and acid being esterified have not more than four carbon atoms.  Alcohols specified are methyl, ethyl, isopropyl and allyl alcohols.  In a preferred embodiment, the vapours evolved from the esterification bath are distilled in a column, an aqueous liquid is added to the condensate obtained therefrom and the resulting mixture is decanted to give an esterrich upper layer and an aqueous lower layer.  Part of the upper layer is refluxed to the column and the remainder washed with water then dehydrated by distillation to give the anhydrous ester as bottoms product.  The wash water is used as aqueous liquid to add to said condensate.  The distillate from the dehydration still is decanted and the aqueous layer distilled to recover alcohol which is recycled with fresh alcohol to the esterification vessel. Detailed examples are given illustrating the preferred embodiment in which (1) ethylacetate is produced by esterifying acetic acid with ethyl alcohol in the presence of butylacetate and sulphuric acid; (2) isopropyl acetate is obtained from acetic acid and isopropanol in the presence of beta-hydroxy ethyl acetate; (3) propyl formate is produced from formic acid and propanol using di-n-butyl ether as auxiliary liquid.  Comparative examples are given in which no auxiliary liquid is present.

Abstract: 212,296. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). April 13, 1920. Lasting and pulling-over. - In a lasting machine of the kind described in Specification 118,288, binding strip is mechanically supplied and mechanically transferred from the forming means to the applying means. The invention is shown applied to the machine described in Specification 118,288. At a predetermined point in the machine's cycle, a clutch 202, Fig. 3, is closed to connect wire straightening and feeding mechanism to a constantly running pulley 204. The wire a is drawn from a reel over a pulley 188 and through a rotating cylinder 190 having extensions 198 with grooves slightly out of alignment. The length of wire required for one binder is, after lubrication, drawn through the cylinder 190 by two oscillations of an arm 274, Fig. 6, operated by worm - wheel pinion, and crank gearing from a worm 252 rotating with the cylinder 190. The arm 274 carries a sliding block having a pawl 272 gripping the wire in one direction. A retaining pawl 288 prevents reverse travel of the wire, and a sliding guide 290 assists in supporting it. The wire now rests on an anvil plate 300, and is cut and bent by slides 304, 306, Fig. 3, operated by pinions 310. The slide 304, which cuts as well as bends, has an inclined face co-operating with a corresponding shear-block 298, Fig. 6, to form a point on the wire. The anvil plate 300, Fig. 9, is now retracted, and the wire pushed by members 384 so that its ends engage supporting blocks 360 on pivoted carrier arms 356. The arms 356 are then swung about their pivots to carry the binder up to the applying means, when the binder is gripped centrally by jaws on a slide and its ends moved along grooves 416, Fig. 14, in members carried by the arms 356, which grooves are then in alignment with the space between the wiper plates 132 and shoe-end embracing plates 150. Spring mounted plungers engage the ends of the binder and centralize it as it is drawn into position in proximity to the driver plates 152. The binder forming and transferring mechanism is actuated by cams on a shaft 318, Fig. 2. A cam 348, driven from the clutch 202 one rotation for each cycle of the machine, has a raised part 354 which actuates a link 352 moving a bevelled member 342 which controls the position of a spring plunger 338 which, when allowed, connects the cam shaft 318 with a constantly rotating member 322 driven by gearing from the pulley 204. Tn prevent the machine being started until the transferring mechanism has been returned to starting position,. the actuating mechanism for the clutch 202 is connected to a pivoted block adapted to engage a collar on the rod operating the main clutch. The heel rest 16, Fig. 19, is free to swing about a pivot 26 under the control of light centralizing springs 32, and may be adjusted about pivots 20 by manipulating clamps 24.
