Filed: 1970-05-29
Abstract: 1308628 Toy vehicles REMCO INDUSTRIES Inc 29 May 1970 [4 Dec 1969] 26163/70 Heading A6S A remote-controlled electric motor-driven toy vehicle is provided with means whereby forward acceleration causes the centre of gravity of the vehicle to shift backwards, the torque produced by the motor during acceleration being such that, assisted by the centre of gravity shift, it causes the front wheels to lift temporarily off the ground as the vehicle starts. The vehicle may be in the form of a "dune buggy" having an inclined hollow structure, 9, representing a surf board, on top which contains a heavy ball 10. Acceleration of the vehicle causes the ball to roll up the slope to the back of the structure 9, by inertia, so producing the centre of gravity shift. In the illustrated embodiment the motor is reversible and the front wheels are provided with a linkage which causes them to swivel to one side when the vehicle reverses. The axles of the wheels are connected to arms 22 and 30 which are pivoted to the body at 23 and 32 and each pivotally connected to a linkage arm 25. This causes the wheels to point forward when the vehicle moved forwards and to take up the illustrated orientation when it moves backwards,

Abstract: 1491108 Platen press for dewatering slurry VICKERYS Ltd 8 June 1976 [19 June 1975] 26172/75 Heading BID  A dewatering press for animal manure comprises a cylinder 11 with an inlet 12, 13  which is closed by movement of a filtering piston 17, 19, the solids outlet end of cylinder 11 being partly closed by a means defining an aperture 28 which expands in response to rising pressure in the cylinder. As shown aperture 28 is defined by an annular resilient diaphragm. Alternative aperture constructions (Figs. 3-5 not shown) are a corrugated or frustc-conical resilient sleeve enclosed by a toroidal bag containing air or liquid under pressure, and an annular plug urged towards the cylinder 11 by a spring or hydraulic ram. The annular nature of these constructions enables tube 24, which has holes 26 whereby additional water is drained from the contents of cylinder 11 and which extends from piston 17, 19, to move with the piston. Water from tube 24 and wire mesh 19 on the piston flows into the piston and thence to outlet 20. Additional water is pressed outwards through perforated section 22 of the cylinder to outlet 23. Fig. 6 (not shown) depicts the self-acting hydraulic circuit which causes ram 15, 16 to reciprocate to move piston 17, 19. The reversal of the movement is controlled by pressure switches (35, 36) which are connected to the ram cylinder, and switch (36) will move the piston rightwards again if it meets excessive resistance in cylinder 11. The response pressures of switches (35, 36) are adjustable. Inlet 12 receives manure already partly dewatered by passage across an inclined screen (10E, Fig. 1 not shown). Suction could be applied to the outside of perforated section 22 of the cylinder 11.

Filed: 1934-09-14
Abstract: 444,247. Drawer &c. fastenings. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. Sept. 14, 1934, No. 26402. Convention date, Sept. 15, 1933. [Class 44] [See also Group XIX] Means for latching a cash drawer in closed position against the action of means urging the drawer to open comprises a bolt having a portion of non-circular cross-section which in one position of angular adjustment of the bolt can pass through a constricted entrance of a slot in a latch plate to release the drawer, but when turned to other positions cannot pass the constriction and thus retains the drawer in closed position. The invention is described as applied to a cash drawer mounted as described in Specification 444,246, [Group XXXIV], for movement within a cash register casing as described in Specification 447,264, the drawer being controlled for release by the keys or a hinged lid in the manner described in Specification 445,691, [Group XIX]. The drawer 7, when released, is opened by a lever 12, Fig. 2, urged counterclockwise by a long spring 18 and bearing by a roller 16 against a plate 17 carried by the rear end of the drawer. The drawer is normally held in closed position by the engagement of the half-round end 29 of a latching shaft 25, Figs. 2 and 3, within a slot 47 in a latching plate 40 secured to the drawer. The shaft is rotatable in a bushing 26 in the casing and carries at its upper end a crank 33, relative longitudinal movements of the various parts being prevented by a bracket 36 engaging beneath a flange 28 of the bushing and secured by a screw 39. Upon the rocking of a lever 61 by the machine, the latching shaft is rocked clockwise and permits the restricted end of the slot 47 to pass the half-round part 29 of the shaft. The drawer is thus released. The latching shaft is retained in releasing position, while the drawer is open, by a spring-urged lever 80, a hook-shaped arm of which takes over a stud 83 on the crank 33. Upon the closing of the drawer, the latching shaft is released, the lever 80 being rocked clockwise by the abutment of a part 88 of the drawer with an arm 86 of the lever. The edges leading to the slot 47 in the latching-plate are inclined to centre the shaft therein and rock it if necessary upon the closing of the drawer. The latching- plate is adjustably mounted by a pivot pin 43 and set-screw 44 on the plate 17 to render the front of the drawer flush with the casing when closed.
