Abstract: 1450909 Electric meters ROBERT BOSCH GmbH 11 Dec 1973 [18 Dec 1972] 57243/73 Heading H2A The armature shaft of an electric motor is guided by a ball bearing whose inner race is secured thereto and whose outer race is axially supported by means of a component in the housing which is held in place by means securing a bearing plate to the housing. A windscreen-wiper motor has a shaft 16 carrying a worm gear 14 for co-operation with the wiper apparatus (not shown). The shaft passes through an aperture in a bearing plate/end cover 19 and has fixed to it a ball bearing 18 secured by a spacing sleeve 26 and retaining rings 25 fitting annular recesses 24 in the shaft 16. The outer race 29 abuts a shoulder 34 and also bears against a support 27 which is generally annular with two extensions 30. Each extension 30 bears against one edge of a nut 21 which is inserted through an opening 33 in the pot-shaped motor housing 12 against which the other edge of the nut 21 bears at shoulder 22. The extension 30 and nut 21 are recessed at 33 (Fig. 2, not shown) to take a finger portion 32 of the cover 19 which prevents rotation of the support 27 and also limits the insertion of nut 21. The cover-plate 19 (and hence bearing 18) are secured by bolts 20 and the nuts 21 to the housing 12 which thus carries the main thrust A on the motor shaft.

Title: Improvements in refrigeration process
IPC: F25J1/00
Filed: 1966-12-22
Abstract: 1,149,560. Refrigerating; gas liquefaction process. AIR PRODUCTS & CHEMICALS Inc. 22 Dec., 1966 [28 Dec., 1965], No. 57403/66. Heading F4H and F4P. In a refrigeration process, compressed helium is cooled by heat exchange, expanded in an expansion engine without liquefaction and further expanded by Joule- Thomson expansion so as at least partially to liquefy. As illustrated, helium is compressed in stages 12, 15 and 17 and passed through heat exchanger 21, liquid nitrogen bath 78, and heat exchangers 28 and 31 to a reciprocating or turbine type expansion engine 33. The discharge pressure of the engine is above the critical pressure of helium. Gas from the engine passes directly to a Joule- Thomson valve 35 and partially liquefied gas is passed into a phase separator 37. Liquid helium may be withdrawn from the system through a line controlled by a valve 38. Vapour from the separator 37 may, by closing a valve 39 and opening valve 40 and 41, be passed through a coil 44 to cool a chamber 45 and then be passed through the shell spaces of heat exchangers 31, 28 and 22 to the input of compressor stage 12. By closing the valves 40 and 41, and opening the valve 39, the vapour may be passed direct to the shell spaces. If product liquid helium is not required, the valve 38 may be closed and a mixture of vapour and liquid passed to the chamber 45. The heat exchanger 28 is cooled by a compression circuit including a compressor 55 drawing helium from the compressor stage 17 and passing it through a heat exchanger 58, the nitrogen bath 78 and a heat exchanger 69 to an expansion turbine 65. Helium from the turbine is passed through heat exchangers 28, 69 and 58 to be returned to a point between the compressor stages 12 and 15. The illustrated compression circuit may be replaced by an independent circuit. The colder components of the system are contained within a chamber 73 and liquid nitrogen from a source is passed through the walls of the chamber to the bath 78. Vapourized nitrogen from the bath 78 passes through heat exchangers 22 and 58 to an exhaust 86. Valves 90 and 91 are controlled in accordance with the amount of liquid helium withdrawn from the process so that the cooling power of the compression circuit increases with the amount of liquid helium required. Preferred operating conditions are disclosed.

Abstract: 664,352. Coke ovens. ALLIED CHEMICAL & DYE CORPORATION. Feb. 27, 1948 [.June 6, 1944], No. 6205. Class 51. (ii). A coke oven comprises a sub-structure formed with a basement space through which air is supplied to the regenerators, the air entering the basement space through a, series of openings in a side wall of the structure and flowing across the space to the regenerator inlet passages. As shown, air is supplied to the regenerators under the control of reversing valves 12 through passages 13 communicating with the basement space 9, the waste gases being discharged into a single flue 10 running the full length of the battery. The air is admitted to the basement space through pairs of upper and lower valve-controlled openings 36, 37 arranged below alternate regenerators in the opposite side wall 8 and supplied with air from a sub-alley 44 connected by louvred openings 46 to an alley 42 communicating with the atmosphere through louvred openings 45.

Under summer conditions, the valves controlling openings 36 are maintained fully open and the valves controlling openings 37 are partially or completely closed so that the major portion of the air enters near the top of the basement space to maintain. a moderate temperature over the full height thereof. Under winter conditions, the position of the valves is reversed so that the air enters at the bottom of the basement space, thereby avoiding excessive cooling of the gas mains 28.

Abstract: Naphth-1-ol-4-sulphonamido derivatives useful in colour diffusion transfer photography e.g. as described in U.K. specification 1,405,662, when made by reaction of a 4-amino-1- naphthol with a dye containing a sulphonyl fluoride substituent, contain impurities including oxidation products of the 4-amino-1-naphthol. These impurities, which detract from the photographic performance of the derivatives, cannot always be removed to a sufficient extent by recrystallisation. According to the invention the crude derivative is dissolved in dimethyl formamide (DMF) or other aprotic solvent and the impurities extracted with petroleum of boiling range from 40 DEG -105 DEG C. The purified derivative may be isolated by mixing the DMF solution (preferably after removal of residual petroleum) with an acid solution or mixing the DMF solution with ethyl acetate and removing the DMF with water followed by crystallisation.
