    • 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 horizontal window blind apparatus having at least a first and a second slat disposed parallel and spaced relative to each other is disclosed. The apparatus includes a first tab which is secured to the first slat, the first tab defining a first opening and a second opening disposed between the first opening and the first slat. A second tab is secured to the second slat, the second tab being aligned relative to the first tab. The second tab defines a third opening and a fourth opening disposed between the third opening and the second slat. A first elongate control extends through the first and the third openings and a first locking device is provided for selectively locking the first control relative to the first tab. A second locking device is provided for selectively locking the first control relative to the second tab. A second elongate control extends through the second and the fourth openings. A third locking device selectively locks the second control relative to the first tab. Also, a fourth locking device selectively locks the second control relative to the second tab. The arrangement is such that relative movement between the first and second control tilts the slats relative to each other so that the slats move between a first disposition thereof in which the slats are open and a second disposition thereof in which the slats are closed.
