Abstract: Projection apparatus comprises a projection lens arranged to project an image from the apparatus and an image carrier (such as an L.C.D. array, film or slide) which is retained in the apparatus in such a way so as to be tiltable about a pivot axis. Because the image carrier is tillable, "keystone effect" typical of projected images may be reduced or substantially prevented. The projection lens is preferably tiltable also and coupled to the tilting of the image carrier to reduce further "keystone effect" and improve image resolution.

Abstract: A method of forming a fusion splice between two optical ribbon cables, which comprises: (i) positioning end portions of the ribbon cables to be spliced in line with one another, and separated from one another by a pre-determined distance; (ii) firing a preparation arc across the ends of the ribbon cables of sufficient energy to soften the ends of the optical fibres forming the ribbon cables and to cause the end of any fibre or fibres (if any) that is/are the most prominent to retract; (iii) firing a fusion arc across the ends of the ribbon cables after a defined period of time following termination of the preparation arc to fuse the ends of the fibres; and (iv) simultaneously with, or subsequent to the fusion arc, moving the ribbon cables toward one another into contact, thereby to effect a fusion splice between the ribbon cables.

Abstract: A closed intravenous (IV) system includes a needle member and a sleeve member, wherein the sleeve member is provided with a resilient seal so that blood is contained after withdrawal of the needle member from the sleeve member. In a first preferred form of the closed IV system, the needle of the needle member extends through a resilient stopper of a fitting and the tip portion of the needle protrudes outwardly from the sleeve. The needle member is withdrawn after a patient's vein has been pierced. In a second preferred form of the closed IV system, the sleeve member is provided with a seal and the needle member is received by the sleeve member, wherein a tip portion of the needle protrudes outwardly from the sleeve. The needle member is withdrawn after a patient's vein has been pierced. A fitting is then snapped into place onto the sleeve member after a downstream IV apparatus has been pre-connected thereto.

Abstract: A contact charger for charging an outer surface of an electrostatic latent image carrier in contact therewith wherein the charging member includes a co-cured polychloroprene and ECO mixture electrically connected to a conductive substrate. The cured homogeneous mixture is covered with an adhesion resistant layer.

Provisions are made for adding variable customized information on at least a portion of each data tag. Such data-tags are readily assembled by hand and are useful as warning signs in an industrial environment.

Abstract: An apparatus for stretching or compressing an ultrashort pulse in time that is free of non-linear and spatial distortion (temporal or spatial frequency chirp) comprises a first diffraction grating G, a concave spherically curved mirror [CCM] with a radius of curvature R.sub.1, a convex spherically curved mirror [CXM] with a radius of curvature R.sub.2, and a flat reflector, [PM]. As a result of propagation of the ultrashort input pulse through this system, the output pulse is either stretched (or compressed) in time so that it now has a duration many times longer (or many times shorter) than its input pulse duration, is spatially uniform (i.e. has no spatial chirp,) and collimated. It can be separated from the input pulse by passage through a Faraday isolator.

Abstract: A lock for a sliding door has at least one locking bolt adapted in use to be moved between an open position and a locking position by activation of an operating member which rotates a pinion which engages a pair of drive racks to cause movement of the locking bolt generally parallel to the longitudinal axis of the bolt and in a direction parallel to a leading edge of a door in which the lock is mounted. The locking bolt is adapted when moved to its locking position to move into locking engagement with a staple-like keep mounted on a frame for the door when the door is in a closed position. A key operated deadlock facility prevents activation of the operating member. Preferably, the lock is also fitted with a safety mechanism so that it cannot be damaged if the door to which it is fitted is closed when the lock is in a locking position, and it is also possible to provide both an automatic latching and a panic feature on the lock.
