Title: Joint prosthesis
Inventor: SHEEHAN JAMES
IPC: A61F2/46
Filed: 1989-02-27
Abstract: A joint prosthesis includes a rigid prosthesis member 10 comprising a head element 11 for articulated cooperation with a complementary prosthesis member (not shown) and an elongate tapered element or stem 12 depending from the head element and adapted for insertion into the fixing in a bone cavity by cement. The prosthesis further includes a reinforcing sleeve 15 surrounding and of slightly greater diameter than the stem 12 and which in use is adapted for embedding in and reinforcing the cement continuously around the elongate element. The sleeve 15 has secured thereto spacing means 18 to space the interior surface of the sleeve from the prosthesis stem 12 and define a space within which bone cement may be received. <IMAGE>
Patent GB-891207-A (GB)
Abstract: 891,207. Valves. PLASCON TANK A.G. June 8, 1960, No. 20213/60. Class 135. The cover a<SP>1</SP> of a fuel container a has a filling pipe b in which is a casing c housing a valve d hinged upon a spindle d<SP>1</SP> which lies outside the axis of the pipe d; the spindle d<SP>1</SP> is attached to the arm e<SP>1</SP> of a float e. As the liquid level in the container a rises the valve d is pivoted towards its seat until the fuel flowing into the pipe b forces it there against at the same same time lifting the float from the fuel. Upon stopping the supply of fuel to the pipe b the pressure on the valve is decreased and the float falls back on to the fuel and partially opens the valve to allow any fuel trapped above the valve to enter the container a.

Title: Drive mechanism for converting rotary motion into reciprocating linear motion
Inventor: MARTIN MICHAEL ROY
IPC: B23D51/16
Filed: 1989-07-11
Abstract: A drive mechanism for a powered hand tool, e.g. an electric saw, for converting rotational motion into reciprocating linear motion comprises a reciprocatable output member (113) coupled to a rotatable drive means by a transfer mechanism incorporating a right angle drive mechanism. The transfer mechanism incorporates a gear (30) which drives a rotatable disc (35) associated with an eccentric cam track (107). A cam follower (111) on one end of the output member (113) engages with the cam track so that rotation of the disc is translated into reciprocating movement of the output member (113). Drive from a motor (20) is transferred to the disc (35) via bevel gearing (30). As shown the cam track (107) is formed in an inverted cam disc (105) rotatable with the bevel gear (35). Alternatively (Figs 7-10) the cam track may be formed on one face of the disc gear. A further embodiment is disclosed (Figs 1-4) in which an eccentric crank arrangement (50, 60) is used to convert rotary motion into reciprocating linear motion. <IMAGE>

Title: Passive seat belt arrangement for use in a vehicle
Inventor: SANDVIK LARS VALTER
IPC: B60R22/06
Filed: 1989-07-18
Abstract: The arrangement comprises a safety belt portion 18 one end of which is attached to a retractor reel 20 and the other end of which is attached to a carriage 22 movable along a rail 24 formed in the door of the vehicle. The carriage carries a tongue which is received in a latching or locking station 30 secured to the door or door frame. The locking station comprises a safety belt buckle which is pivotally mounted in position, but which normally occupies a position in which the plane of the buckle is parallel with the plane of the rail to enable the tongue to be easily inserted into the buckle. However, in the event that an accident arises the buckle can pivot so that the force applied to the buckle by the safety belt is axial of the buckle. The buckle is restrained against pivotal movement by a frangible plate (38, Fig.3) and fingers 42 which straighten or break in the event of an accident, or by a frangible arm (90, Fig.5) and a spring (84, Fig.4). <IMAGE>

Title: Disposal of empty containers
Inventor: GILL DAVID CHARLES
IPC: B65D77/06
Filed: 1989-09-18
Abstract: Containers of the type having a rigid outer casing 4 accommodating an inner liner 2 are disposed of by removing the outer casing 4, expelling air remaining in the liner 2, and placing the liner 2 in a waste receptacle 10. The casing 4 is disposed of separately. When full, the waste receptacle 10 is disposed of in its entirety by means appropriate to the nature of the former contents of the containers. For example, disposal of the receptacle 10 may be undertaken by specialist contractors. This relieves the users of the containers (which may formerly contain herbicide) from the responsibility of disposing of them safely. <IMAGE>

Title: High intensity infra-red pyrotechnic decoy flare
Inventor: PELHAM PETER GEORGE
IPC: C06C15/00
Filed: 1992-09-16
Abstract: An aircraft-launched pyrotechnic decoy flare for luring an incoming missile away from the aircraft's exhaust which comprises a compactly clustered substantially void free array 2 of discrete pieces of a gassy high intensity infra-red emitting pyrotechnic composition contained in a rupturable air-tight contained 4. On ignition of the flare, combustion spreads rapidly along the interfaces between the discrete pieces to produce gaseous combustion products. When the pressure within the air-tight container reaches a predetermined level the container ruptures and the discrete pieces burst apart. The plurality of pieces have a large combined surface area over which combustion occurs and so produce a high intensity emission of infra-red radiation. In a preferred embodiment the discrete pieces comprise a mixtured fibrous activated carbon cloth impregnated with a metallic salt and coated with a mixture of an oxidising halogenated polymer, an oxidisable metallic material and an organic binder. When an incoming missile is detected expulsion charge 8 and starter charge 10 are ignited, the casing 4 leaves the launch tube 20 and the pellet is ignited via train 12 and 16 and explosive charge 18, the spring shutter 14 having been released by the casing leaving the launch tube. In a second embodiment a second flare is launched via a time delay fuse 0.2 seconds after the first flare. <IMAGE>

Title: Vacuum pump with pendulum action.
Inventor: EARLE STEPHEN RICHARD
IPC: F16J1/12
Filed: 1992-12-17
Abstract: A piston type vacuum pump has a connecting rod 21 fixed to the piston so that the piston rocks in its cylinder bore 12 during reciprocation. Articulation of the piston 14 is accommodated by a seal 15 having a depending sealing lip 17. The lip 17 may act as an outlet valve. The seal 15 may have an outwardly extending support ring (19, Fig. 3) to relieve the sealing lip of piston reaction loads; this both centralizes the piston in the bore and permits the seal to be designed for effective sealing rather than piston support and sealing. <IMAGE>

The blocker valve segments 46 are carried on the sleeve valve 44 for simultaneous deployment. The segments are adapted to delay the opening of the side outlets 34 as the sleeve valve translates axially. Specially extended segments co-operate with a shaped duct wall adjacent the outlets to delay their uncovering. The sleeve valve 44 is moved by four actuators 52. <IMAGE>
