Abstract: 287,550. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). March 24, 1927, IConvention date]. Motors, cooling; casings and supports; driving arrangements; terminals and accessories, mounting on machines.-An electric motor for driving textile spindles or other drives at high speeds is mounted under the fly frame with its shaft extending upwards to form the spindle and is cooled by air passing through conduits on the motor casing and in the bearing wall, the air being drawn in and thrown outwards by a screen-plate carried by the shaft. The motor as a whole may be interchangeably mounted in the fly frame without the use of screwed joints. Fig. 1 shows an alternating-current motor with its rotor shaft carried by an upper bearing 7 having ducts 8. These ducts, together with the ribbed surface 6 of the casing, form channels for the cooling air drawn in and ejected, as shown by the arrows, by a screen-plate 9 on the shaft 4 which is extended to form the textile spindle. The screenplate may be massive enough to act as a flywheel. Fig. 3 shows a spindle motor detachably mounted in the fly frame 13 and retained by springs 18 which engage a slot 16 in the member 13. The motor casing carries a push-button switch 23 and spring terminal contacts 22 which engage bare current bars 21 under the fly frame when the motor is pushed home. This elastic mounting enables the spindle to adjust its position freely when running at high speeds. Cooling is effected by air drawn through ducts formed in the bearings and, continued by ribs on the motor casing and an enclosing shell 24.

Abstract: 491,770. Friction clutches. GENERAL MOTORS CORPORATION. Feb. 25, 1938, No, 5985. Convention date, Feb. 27, 1937. [Class 80 (ii)] The presser plate 43, Figs. 1 and 2, of a friction clutch is actuated by a Belleville spring 59, the outer edge of which bears against the plate 43 while a circular series of headed projections 65 on the cover plate 31, secured to the driving flywheel 27, pass through openings 63 formed in the spring 59. A ring 75 encircling the projections 65 is disposed between the spring and the heads 67 of the projections 65, while a similar ring 77 is disposed between the spring and the plate 31. The spring is stressed during assembly so as normally to move the plate 43 to engaged position while reacting against the ring 77. To relieve the clutch pressure, the spring is further stressed by inward movement of a control sleeve 105 so that the spring presses against the ring 75. Metal stampings 79 may be arranged on the projections 65 between the spring 59 and the ring 77, some of these stampings having hooked ends engaging recesses 81 in the plate 43 so that the latter is moved positively to disengaged position. As shown in Fig. 1, the projections 65 are in the form of rivets, but they may be in the form of tongues 103, Fig. 15, struck out from the plate 31. In such form, the separate ring 77 may be replaced by a bead 97 formed on the plate 31 and the ring 75 may be in the form of a bead 101 on a plate 99 which is apertured to pass over the tongues 103, the free ends of the latter being subsequently bent to retain the parts. The plate 43 is in driving connection with the plate 31 by the engagement in axial grooves in the former of studs 47, Fig. 1, secured to the latter. The studs may, however, be replaced by tongues struck from the plate 31 or by projections on plates which are riveted or welded to the plate 31. The spring 59, radially inwardly of the openings 63, is formed with radial slots 71 to form fingers 73. In order to secure the fingers to the sleeve 105, a ring 109 is interposed between the fingers and a ring 111, provided with axial lugs 113 engaging recesses in the sleeve 105 and with axial lugs 115 engaging the slots 71, while a ring 117 bearing against the fingers 73 is formed with axial lugs 119 which pass within the fingers and the ring 111 and which have outwardly-turned portions 121 engaging an annular recess in the sleeve 105. In place of the member 117, 119, 121, double coil springs 125, Fig. 17, may have a junction part 123 engaging a hooked part 127 of the sleeve 105 while their free ends engage behind the fingers 73. The plate 31 may be hexagonal, as shown in Fig. 2, or may be square, and may have portions cut away for ventilation purposes. The plate 43 may have fins for circulating air.

Title: Improvements in or relating to removal of salts from acetone-phenol mixtures
IPC: C07C37/72
Filed: 1953-03-04
Abstract: In the production of phenol and acetone from cumene hydroperoxide by decomposing it in the presence of catalytic amounts of an acid (e.g. an inorganic acid such as sulphuric acid) and neutralizing the acid and acidic organic impurities in the oxidation mixture (e.g. with an aqueous solution of sodium phenolate), the salts produced by the neutralization are removed by adding, before or after the neutralization step, an amount of water sufficient to form, on neutralization and settling, an organic upper phase containing substantially all the phenol and acetone and some water, and an aqueous lower phase containing in solution substantially all the said salts and having a volume equal to at least 5 per cent (but preferably not exceeding about 50 per cent, e.g. about 8-20 per cent) of the organic phase, and separating the two phases.  The addition of water and settling are advantageously effected at about 50-150 DEG F. (preferably 70-90 DEG  F.).  The aqueous phase, or part of it, may be recycled to the decomposition mixture, whilst the organic phase may be subjected to fractional distillation to recover the phenol and acetone.  The cumene hydroperoxide may be obtained by oxidizing liquid-phase cumene with an oxygen-containing gas (e.g. air) in the presence of an aqueous alkali to form a mixture of cumene hydroperoxide and unreacted cumene. and removing substantially all of the latter. The decomposition of the cumene hydroperoxide may be effected at about 150-300 DEG  F., advantageously in the presence of acetone or other inert diluent miscible with water and with acetone. Suitable arrangements of apparatus are described with the aid of flow sheets, and a detailed example is given.  Reference has been directed by the Comptroller to Specifications 626,095, 629,429 and 684,039.
