Filed: 1925-01-06
Abstract: 237,551. Silica Gel Corporation, (Assignees of Miller, E. B., and Benzon, A.). July 22, 1924, [Convention date]. Refrigerating, vacuum machines and processes for.-In processes wherein the vapour of water, brine or other liquid in an evaporator is adsorbed by a material such as silica gel or active charcoal, as described in Specifications 225,191 and 228,136, the adsorbent is mechanically circulated between an adsorption chamber 213, Fig. 1, and a concentrating or activating chamber 239, while the vapour driven off in the activating chamber is condensed in a chamber 234, Fig. 2, and returned through a pipe 243 to the evaporator 210, the process being a continuous one. The adsorber and evaporator are maintained under vacuum by a motor driven pump 214, Fig. 2, communicating with the adsorption chamber, and in order to avoid the use of stuffing-boxes the motor driving the mechanism for stirring and circulating the adsorbent is housed in a casing 255 in communication with the interior of the chamber 213. The adsorbent is used in granular form, as in the process for separating gases from mixtures described in Specification 227,309. [Class 1 (i), Chemical processes &c.], and is fed into the adsorber through a passage 238, Fig. 1, and carried around the adsorber chamber by suitable means, such as a series of rings 252, Fig. 3, having pockets 252a at one side, the rings being of rectangular cross-section with an annular discharge opening 252b at the side opposite the pockets. Radial baffles 252<c> may be provided in the interior of the rims of the rings. The material as it leaves the last ring of the series falls into a hopper from which it is fed by a screw 259 into the activating chamber. A reversed screw 258 serves to force the material upwards into a hopper 260 over which it falls, the material in the hopper acting as a seal against the flow of vapour between the chambers. The activating chamber may be fitted with stirring-paddles 262, and the material is conveyed back to the adsorber by a screw 241 surrounded by a cooling-jacket 270<a>. A reversed screw at the end of the screw 241 forces the material upwards through the passage 238. The rings 252 are spaced apart by sleeves 252<c> on the driving-shaft 248, and are secured together as a unit by rods 252e engaging flanges 252<d>. The shaft 248 is driven from the motor by worm gearing 257, 254, and the lower screw 241 and the paddles 262 are driven by chain and sprocket gear from the shaft 248. The adsorption chamber is separated from the activating chamber by a partition 246 and a heatinsulating disc 246<a>, and is fitted with an end cover 245. The vapours driven off from the activating-chamber pass to the condenser through a passage 242. The activating-chamber may be heated by a gas burner 261 or other means.

Abstract: 1,272,375. Ratchet clutches. RINGSPANN ALBRECHT MAURER K.G. 6 Jan., 1971 [31 Jan., 1970], No. 550/71. Heading F2C. A one-way sprag clutch comprises a driving inner race 2 and a driven outer race 3, the sprags 1 rotating with the inner race and being formed with tilting bearings 4 abutting rings 5, 6 rotating with the inner race, the sprags being tilted about the rings by centrifugal force to remove the sprags from contact with the outer race above a predetermined speed. The axis of tilting of the sprags may be formed at the centre of curvature of the contact surface la of the sprags with the inner race so that the sprags remain in contact with the inner race above the predetermined speed. As shown, the bearing surfaces 4 are formed at the ends of the sprags and abut flanges 7, 8 on the rings 5, 6. Individual biasing springs 9 urge the sprags to their engaged position. Again, Figs. 5 and 6 (not shown), the bearing surfaces are formed as stub shafts (15), (16), on opposite ends of the sprags. Also, Figs. 7 and 8 (not shown), the two end rings (19), (20) may be interconnected by bolts (21) on which the individual biasing springs 9 are mounted. The ring (20) is attached to the inner race by an undersized normally polygonal ring (25) surrounding the race and engaging in a groove (26) in the ring (20). The sprags may be mounted in a cage formed from separate links (27), Figs. 9-12 (not shown), having central notches (28) to receive a ring (29) against which the sprags abut to pivot about central cylindrical bearings (33). A tension spring (30) connects the free ends of an incomplete cage when the circumferential length of the required cage is not a whole number of links. By inserting rollers (35), Figs. 13 and 14 (not shown), between the inner race and ring (29), the ring rotates with, and is centrally supported on, the inner race.
