Title: Vehicle lift
IPC: B66F7/18
Filed: 1965-10-07
Abstract: 1,112,437. Garage lifts; hydraulic jacks. J. J. PELOUCH. 7 Oct., 1965 [8 Oct., 1964], No. 42633/65. Headings B8H, B8J and B8L. A garage lift comprises a pair of telescopic arms 139, 140, provided with adjustable vehicle engaging pads 153, pivotally mounted on supports 133 at each end of a beam 131 secured to the piston of an hydraulic ram 40. Each pad 153 is pivoted about a vertical axis on the associated arm and is adjustable to provide alternative vehicle - engaging surfaces at different heights, Figs. 21-23 (not shown). The ram 40 is mounted in a pit 32 which is adapted to accommodate the beam 131 and supports 133, thereby leaving only the arms 139, 140 above ground level. The pit 32 is provided with pivoted door assemblies (165-167), Figs. 1, 14-19 (not shown), which are adapted to close automatically on lowering of the beam 131. The ram 40 comprises a hollow piston 43, Fig. 4, and an air conduit 68 extending down the inner wall of the cylinder to a conduit 69 leading to a conduit 71 which passes through a check valve 96 in the bottom wall 46 of the piston. A tube 73 provided with apertures 77 is secured to the top wall 46 of the piston and extends into the conduit 71. On supplying compressed air to the interior of the piston, hydraulic fluid in the piston passes through the check valve 96 and through a control valve 102 into the cylinder. As the apertures 77 in the tube 73 rise above the top of the conduit 71 the flow of air into the piston increases and thereby accelerates the piston. The valve 102 comprises a spindle 106, Figs. 10-13 (not shown), secured to the valve member (105) and coupled to an operating lever 129, Fig. 2. The valve member (105) is pivoted at (108) to a plate (109) which is pivotally supported at (110) and which pivotally supports a latch (112). A bar 117, Fig. 4, is secured to the inner surface of the cylinder wall and when the latch is adjacent the bar the latch pivots the plate (109) against the action of a spring (114) to prevent closing of the valve, Figs. 10, 11 (not shown). Safety stops 119, Fig. 4, are secured to the cylinder wall and are adapted to engage the latch (112) to prevent accidental lowering of the piston. To lower the piston, the conduit 68 is connected to atmosphere through a valve 66 and the spindle 106 is moved down to open the valve and to pivot the latch (112) away from the stops 119 and bar 117. The piston is provided with a float 88, Fig. 7, 8 (not shown), movable on guides 87 and coupled to a valve assembly 81 whereby, if the hydraulic fluid in the piston falls below a predetermined level 48, the valve opens and connects the interior of the piston with atmosphere.

Filed: 1973-09-11
Abstract: 1394763 Extrusion sintering SOC ITALIANA RESINE SIR SpA 11 Sept 1973 [20 Sept 1972] 42744/73 Heading B5A An acrylonitrile-butadiene-styrene copolymer powder is formed into granules of the sintered powder, by extrusion through nozzles at a temperature below the melting point of the polymer, and chopping the extrudate into the granules. The extrusion conditions comprise a powder temperature of 120 to 150‹ C. and a pressure of 300 to 500 atm., and nozzles having a diameter of 1À5 to 4 mm. The particular examples relate to acrylonitrile-butadiene-styrene copolymers prepared by graft polymerization of monomeric styrene and acrylonitrile on a polybutadiene latex by the emulsion process, and some of the examples relate to pigmentation of the granulate which is facilitated by its sintered nature. The acrylonitrile-butadienestyrene copolymer powder may be obtained from the emulsion by coagulation, separation, and drying, or alternatively by spray drying, or drying on heated rolls. The granulate is chopped by the action of stationary or rotating knives, that co-operate respectively with a rotating or stationary extrusion die of a pellet mill comprising, e.g. a rotating die and pressing rolls which frictionally heat the powder.

[Also in Division B5] A roll of tubular thermoplastic film 40 is fed by rollers 44, 46, 48, 50 past electric eyes 56, 58 which periodically stop the feeding so that the tube can be gripped by belt clamps 52a, 52b to permit a knife 60 to sever the tube adjacent a seal 54b and form a one-piece bag sealed at its bottom end with either two adjacent or all four corners chamfered. After severing the bag is fed laterally by the belt clamps to strike a projection 68 which opens the bag to admit a filling nozzle 70. The bag may be subsequently closed by a tape. The tubular film is notched to form the chamfers, and sealed by a prior process, but in a modification the film is notched, and sealed by a mechanism (80, Fig. 8, not shown) adjacent the knife.

The plate 20, on which the further pedal 24 is adjustably mounted, may be rigidly (as shown) or pivotally secured to the pedals 13, 14. The hydraulic system includes a pressure line 35 supplied by a reservoir 45 and pump 52, a return line 36 and a line 37 to at least one actuator 49. The valve spool 31 is subject to a pedal force from the spring 32 opposed by a spring 33 and braking pressure in a chamber 34 connected to the brake line 37 through a restriction 42 and fast drain line 43. Movement of the spool 31 from the position shown cuts off the fast drain line 43, then the return part 40 and finally connects the pressure line 35 to the actuator 49. The increasing pressure in the chamber 34 mould the spool to the right cutting off the pressure line 35, leaving the spool balanced between the force of spring 32, which is communicated to the pedal 27 and the spring 33 and fluid pressure in the chamber 24.
