Title: Improvements in or relating to a hydro-pneumatic suspension unit for vehicles
IPC: F16F9/092
Filed: 1966-04-04
Abstract: 1,135,449. Hydro-pneumatic, self-levelling, suspension unit. HOESCH A.G. 4 April, 1966 [13 April, 1965], No. 14870/66. Heading F2S. In a self - levelling hydro - pneumatic suspension unit when a piston 7 moves downward below a throttle port 23 in a cylinder 8 working liquid is pumped into a bottom chamber 9 and through a non - return valve 12 in a valve plate 10 and into a pressurized working chamber 11 corresponding upward movement of the piston 7 causing liquid to be drawn into the cylinder 8 from a pressurized storage chamber 16 the liquid passing through a throttle pipe 20, a non - return valve 21 in the valve plate 10, and the bottom chamber 9. For oscillations of the vehicle at normal amplitude liquid is transferred into and out of the working chamber 11 through the throttle port 23 and a duct 24 a pump by-pass 36 being provided in the valve plate 10 if the full output of the pump is not required. When the piston 7 moves out of the cylinder 8 so far that a throttle port 22 is opened liquid flows from the working chamber 11 to the storage chamber 16 through the duct 24, the throttle port 23, the cylinder space, the throttle port 22, and the throttle pipe 20. The pipe 20 and duct 24, formed in the wall of the cylinder 8, are separated from the gas compartment 11a of the working chamber 11 by a tube 33 which also serves as a spacer between a partition 25 and the valve plate 10. The outward movement of the piston 7 is limited by the engagement of spring-loaded balls 28 in an annular groove 30 in the piston 7. In a modification, Fig. 3, not shown, when the piston (7<SP>1</SP>) descends below a duct (24<SP>1</SP>) in the wall of the cylinder (8<SP>1</SP>) liquid is pumped from the cylinder space past a non-return valve (23<SP>1</SP>) through a duct (35<SP>1</SP>) in the piston (7<SP>1</SP>) and into a working chamber (11<SP>1</SP>) disposed on the outer end of the piston (7<SP>1</SP>). Upward movement of the piston (7<SP>1</SP>) causes fluid to pass into the cylinder from the storage chamber (16<SP>1</SP>) through the non-return valve (21<SP>1</SP>) and the bottom chamber (9<SP>1</SP>) until the piston (7<SP>1</SP>) reaches the duct (24<SP>1</SP>) whereupon, for normal amplitude oscillations, fluid passes to and from the working chamber (11<SP>1</SP>) through the piston duct (35<SP>1</SP>) radial ports (23<SP>1</SP>) and an annular groove (34<SP>1</SP>) in the piston. The working chamber (11<SP>1</SP>) communicates with the storage chamber (16<SP>1</SP>) when the annular groove (34<SP>1</SP>) reaches a throttle bore (22<SP>1</SP>) in the cylinder (8<SP>1</SP>). A pump by-pass duct (36<SP>1</SP>) may be provided. The unit is provided with co-operating stop members (37<SP>1</SP>), (39<SP>1</SP>). In a further modification, Fig. 4, not shown, the working chamber (11<SP>1</SP>) is located in a hollow outer skirt (38<SP>1</SP>) so that the length of the unit is minimized.

Patent GB-810008-A (GB)
Title: An improved process for shaping resinous materials
Inventor: HUGHES HARRY
IPC: B29C33/38
Filed: 1956-05-18
Abstract: Shaped articles are manufactured by pouring a fluid slip comprising or consisting essentially of a resin in liquid suspension into a porous mould which absorbs the liquid of the slip to leave a coherent cast which is then removed and sintered by heating.  The slip preferably comprises an aqueous suspension of resin, e.g. polyvinyl chloride, polyethylene, or a polymerized hologenated ethylene, e.g. polytetrafluorethylene, containing a dispersing agent and a filler such as finely ground alumina or silica.  If the suspension is rich in filler it may also contain a temporary binder, e.g. gum arabic, which is decomposed when the cast is sintered.  The mould may be of plaster of Paris, and the absorption of liquid therein may be facilitated as by subjecting the slip to centrifugal force.  The cast is preferably removed from the mould and dried before sintering it, and the mould surface may be coated with a release agent such as sodium alginate.  A hollow cast of about 1/8 inch wall thickness and containing 30 per cent. by weight of polytetrafluorethylene and 70 per cent. of finely ground alumina may be sintered at 400 DEG C. for about 30 minutes.
