    • Rotary inlet/exhaust valve for internal combustion engines having seals employed to minimise gas leakage around cylindrical valve rotor (12) which rotates with a radial clearance gap within a receiving bore of the engine. Rotor (12) comprises a main cylindrical body (40) having a rectangular exhaust port (48) formed on the circumferential surface of rotor (12) with angular spacing from inlet port (46). Sealing elements (70, 80, 90) are received in respective grooves (60, 64, 68) formed on the circumferential surface and arranged to bridge the radial clearance gap to create over each discrete surface zone, discrete volume sectors that rotate with rotor (12). Each annular sealing element (70) consists of a pair of sealing rings. Rotor (12) incorporates a pressurizing system arranged to selectively direct a pressurized fluid in between each sealing ring pair (70) to bias the rings in axially opposite directions to prevent high pressure gases from breaking the seal between the flanks of sealing elements (70) and the end faces of sealing elements (80, 90). This prevents ring seals (70) from moving away from the side surfaces of groove (60), and hence away from the end faces of sealing elements (80, 90).

    • A rotary valve (1) for an internal combustion engine, comprising a cylindrical valve rotor (2) having an inlet and an outlet port (3, 7) arranged in the circumferential surface thereof, and a plurality of sealing elements (13a, 13b, 14a-14f) mounted on the valve rotor (2) such as to subdivide the circumferential surface of the rotor body (2) to define discrete circumferential surface zones thereon, a predetermined one of the discrete surface zones being arranged such that, when the rotary valve (1) is received within a valve bore in a cylinder head of an engine and the sealing elements (13a, 13b, 14a-14f) of the rotary valve (1) abut on the valve bore surface, it periodically seals-off a transfer port in the cylinder head, for which the rotary valve (1) serves as closing and opening means, during at least part of the compression and combustion strokes performed in the engine, whereby air-fuel mixture compressed during the compression stroke and combustion gases created during combustion stroke are substantially prevented from passing into the inlet or outlet port (3, 7) of the valve (1) during these strokes.

    • A pair of wheel assemblies (26, 28) are vertically spaced apart and are supported for rotation about parallel axis (30, 38) by a common support frame (l0). Each wheel assembly (26, 28) comprises a pair of wheels at its ends (38, 40). The wheels (34, 40) have radially outwardly opening channel portions (80) in which traveling bearing pads (64, 66) are received. The bearing pads are secured to endless support cables (46), and also to the end portions (l52) of carrier beams (l50, l94) which extend between the two wheels (34 or 40) of each assembly (26, 28). The carrier beam (l50, l94) is an upper portion of a carrier (48, 48′, l76) onto which is placed a motor vehicle or some article which is to be stored. A first drive cable section (54) is connected to the support cable (46) and extends therefrom to a winch drum (50). A second drive cable section (58) extends from the support cable (46) in the opposite direction to the same winch drum (50). When the winch drum (50) is rotated in one direction, it pulls on one of the drive cable sections (54, 58), and the second drive cable section (54, 58) is unwound from the winch drum (50). When the direction of rotation of the winch drum (50) is reversed, the first drive cable section (54, 58) is paid off of the winch drum (50) and the second drive cable section (54, 58) is wrapped onto the winch drum (50).

    • A compressible stud assembly is capable of being longitudinally compressed when an external force is applied. Preferably, the assembly comprises a stud connecting screw (A) housed within a stud body (D) which is movable relative thereto, a compression space located adjacent a head of the screw, and a resilient member (C) which may be compressed, in use, by the stud body. The resilient member may comprise a high density rubber washer, a metal spring, or a polyurethane elastomer. The compression space is typically provided between an end cap (E), which may be secured to the stud body, and the screw. The assembly is preferably mounted, in use, within a recess (Fig. 5B) in a footwear outsole. A further stud is disclosed (Fig. 4), which is shaped such that it comprises a square concave base with rounded corners, the base tapering upwards into a rounded end.
