Abstract: 908,558. Variable-speed gear; friction clutches. GENERAL MOTORS CORPORATION. June 8, 1961 [July 5, 1960], No. 20735/61. Class 80 (2). Continuously-variable ratio planetary gearing comprises an input shaft 12 rotating a drive disc 17 engaging planetating discs 31 which turn on spindles 32 mounted in a support band 33 and run over a reaction ring 36 fast with a casing 10, a driven disc 56 splined upon an output shaft 16 engaging the inner surfaces of the planetating discs and being slidden axially to give ratios which extend from reverse through neutral to forward drive. In the form shown, the planetating discs 31 have frusto-spherical outer surfaces 35 which engage frictionally a corresponding surface 19 on the drive disc 17, and also engage frictionally a surface on the reaction ring 36, but in a modification, Fig. 3 (not shown), the planetating discs are formed with two rings of teeth meshed by teeth on the drive disc and on the reaction ring. The planetating discs 31 roll on a free clutch ring 46, and also on a free support ring 38. Drive is transmitted through the gear when liquid under pressure is admitted through a port 26 to a space 24 sealed by a ring 23 to bias the drive disc 17 rightwards into engagement with the planetating discs 31. The ratio is varied by selectively supplying liquid under pressure through ports 76, 77 in a cylinder 66 containing a piston 71 fast with a sleeve 63 connected through a bearing to the driven disc 56, which is mounted upon the output shaft 16 by ball splines 59. When the gearing gives a variable ratio between its input and output shafts, the clutch ring 46 is free, and the planetating discs 31 roll freely upon it. When the driven disc 56 moves leftwards to its directdrive position, a frusto-conical friction surface 58 thereon engages a corresponding surface on the clutch ring 46, and forces the latter into frictional engagement with the drive disc 17, moving the latter against the bias of the liquid in the chamber 24 out of engagement with the planetating discs 31.

Abstract: 631,423. Friction shock absorbers. MINER, Inc., W. H. July 31, 1947, No. 20873. Convention date, Jan. 18, 1946. [Class 108 (iii)] A friction shock absorber comprises a pair of relatively slidable friction elements D, E having interengaging friction surfaces on the inner sides thereof, each element having a lug 144 at its outer end engageable with the lug of the other element to limit lengthwise separation of the elements, and a spring F opposing relative lengthwise movement of the elements D towards each other. Each element E, D is formed with'a base portion 111 which carries a flange 112 forming an abutment for the respective end of the spring F. Each element E, D also has a flat friction surface 113 inclined with reference to the axis of the shock absorber. The surface 113 is slotted to accommodate the lug 114 formed on the extremity of the other portion D or E respectively. The base 119 of the slot is inclined similarly to the surface 113 in order to co-operate with a similarly inclined surface 120 on the corresponding lug 114 to provide additional friction damping. In a modified construction (Figs. 1-3, not shown), there is no frictional engagement between the surfaces 119, 114 which are of semi-circular cross sections. Each abutment flange 112 is thickened at a in order to provide a support for spring at a point diametrically opposite to the end portion b of the spring. Each base portion 111 is slightly eccentrically disposed relative to the spring axis so that it is in engagement with the spring at b but is spaced from it at a by a substantial clearance, thereby forcing the friction surfaces into engagement. Each element D, E has a strengthening rib 16. The spring is preferably under initial compression.

Title: Process for the recovery of precipitated tungstic acid catalysts
IPC: C07C31/26
Filed: 1962-05-31
Abstract: In the hydroxylation of water-soluble olefinic compounds by hydrogen peroxide using a colloidal suspension of tungstic acid as catalyst, the catalyst is separated from the product by flocculation by contact with activated alumina, leaving a clear supernatant liquid to float above it (see Division C1).  The example given refers to the hydroxylation of allyl alcohol to glycerol.ALSO:Tungstic acid is separated from liquids resulting from the hydroxylation of water-soluble olefinic compounds by hydrogen peroxide containing a colloidal suspension of tungstic acid, by contacting the reacted liquids containing the suspension with activated alumina for 5 minutes to one hour at 20 DEG  to 100 DEG  C. to flocculate the acid, separating the alumina and suspension, and recovering the tungstic acid by decanting, filtering or centrifuging. The alumina contact may be assisted by agitation or hydro-fluidization.  With such assisted contact, the alumina may be 0.1 to 2 mms. in size and amount to 0.1% to 10% by weight of the colloidal suspension and may be contacted at 80 DEG  C. for 15 or 20 minutes. Alternatively, the suspension may be passed over a stationary bed of alumina of size 2 to 10 mms.
