Title: Gearshift protection device
IPC: F16H63/44
Filed: 1981-10-26
Abstract: A device is provided for preventing a gearshift directly from a first lane (V-VI) to a second, non- adjacent lane (I-II) in a multi-lane gearshift of a transmission. In the device a pair of directional control devices 12, 13 control supply of fluid pressure from a source 15 to a blocking cylinder 17, the piston of which has a spring action return stroke, and to a range switching cylinder 16. In the neutral position on the V-VI lane fluid is supplied to the blocking cylinder 17, moving the piston into a position where it prevents movement in the direction 30 by obstructing the shaft 1. Upon movement towards the III-IV intermediate lane, the plunger 9 is pushed in and the plunger 10 becomes extended. The valves 12, 13 then act to relieve pressure from the cylinder 17, to unblock the path. Pressure relief is delayed by the throttle 19 so that the path remains blocked against immediate selection of the I-II lane. <IMAGE>

Patent GB-2098496-A (GB)
Title: Improved distillation apparatus
IPC: B01D1/06
Filed: 1981-10-19
Abstract: Distillation apparatus in which a group of pairs of heat-transfer tubes (7) are each driven to wobble about a vertical axis which passes through a wobbling center (30), (64-67). A stream of fluid (101) is directed to flow down inside each tube. The fluid stream tends to cling to the inner surface of the tube away From the wobbling center while it revolves with respect to the tube in response to the wobbling motion. The revolving flow stream (6) wipes the inside surface of the tube (7) to form a thin film (5) which offers low heat resistance to facilitate the evaporation, carries away the residue by its lateral motion and carries the reflux downward with little restriction. To provide an improved dynamic balance of the tubes during wobbling, in a preferred form the tubes are mounted in two pairs of tube groups (403), (404) and (403'), (404') with each pair of tube groups mounted symmetrically about an associated vertical axis. The tube mounting has means (410), (410') for restraining the tubes from rotation about this vertical axis while allowing the wobbling. Each pair of tube groups has a drive shaft (406) and an eccentric drive system (405), (405'), (401), (401'), (402), (402') connecting the shaft to the tube groups.

Title: Densification of pulverised waste matter into fuel cubes
Inventor: EDWARDS RAYMOND
IPC: C10L5/44
Filed: 1982-07-21
Abstract: The densified fuel cubes are made by extrusion from a roller and ring apparatus, of the waste matter which is fed into the apparatus as a mass of pulverized carbonaceous matter having a particle size not exceeding 3/8ths inch. The fuel cubes have a bulk density of between 30 and 60 pounds per cubic foot and a heat value of not less than 8000 btu. The fuel cubes (150) are broken off, on issuing radially outwardly from horizontal and circumferentially disposed extrusion passages, of stationary die means (90) which are clamped between plates (23, 25). The extrusion is effected by wheels (rollers) (66, 68), which freely rotate on spindles (69), mounted upon a driven shaft (40) for orbiting rotation radially interiorly of the die means (90). The pulverised matter is gravitationally fed at an inlet (21), onto an inverted feed cone (45) which is also rotated by the shaft (40), and carries paddles (49) which distribute the matter to fall through apertures (51) of the upper plate (23), into the path of the orbiting rollers (66, 68). The die passages are longitudinally grooved to increase compacting friction on the matter. <IMAGE>
