Abstract: A retrofitable retractable screen system for use with windows or doors. Instead of using a spring based tensioning arrangements to rewind the screen onto the roller assembly, the arrangement uses a pulley located on the spindle, around which is wrapped a cord. A guide assembly guides the cord around a tension adjustment arrangement that adjusts the tension in the cord as the screen is wound and unwound from the spindle to provide a smooth mechanism to extend and retract the screen. When the screen is extended, pushing the edge of the screen to force retraction of the screen is translated into a pulling action on the cord to unwind the cord off a pulley, which drives rotation of the spindle to wind the screen back on. Conversely, pulling the distal edge to extend the screen rotates the spindle and pulley to wind the cord back onto the pulley.

Abstract: A screen system for use with a sliding panel of a window or door to screen an opening as the sliding panel or door is opened. The screen is attached to the edge of the sliding panel adjacent the opening, and is wound onto a spindle. The spindle is rotatably mounted adjacent the screen opening so that the screen can be unwound from or wound onto the spindle. A cord is connected between the sliding panel and the spindle pulley via an idler pulley. The spindle is caused to rotate to wind the screen onto the spindle as the sliding panel is slid towards the closed position. While the screen is wound off the spindle, the cord is wound onto the spindle pulley and vice versa. A tension adjustment arrangement is provided for adjusting the tension in the cable as the screen is wound and unwound from the spindle.

A cord is connected between the sliding panel and the spindle pulley via an idler pulley. In this arrangement the spindle is caused to rotate so as to wind the screen back onto the spindle as the sliding panel is slid towards the closed position. While the screen is wound off the spindle, the cord is wound onto the spindle pulley and vice versa. As the A tension adjustment arrangement can also be provided that is configured to adjust the tension in the cable as the screen is wound and unwound from the spindle due to the change in diameter of the cord around the spindle pulley.

Abstract: A lockable shield assembly for a syringe is described. The lockable shield assembly includes a moveable sleeve adapted to slide longitudinally along a body of the syringe from a retracted position where the needle of the syringe is exposed to an extended position wherein the moveable sleeve covers the needle. The assembly further includes a saddle member for attachment to the body of the syringe with the saddle member including a resilient tongue biased outwardly from the saddle member, wherein the resilient tongue engages with an abutment region located on the inner surface of the moveable sleeve to prevent retraction of the moveable sleeve when it has been moved to the extended position.

Abstract: The invention is a shield (11) for a syringe (10) with a needle (18) where the shield (11) is moveable between a retracted position where the syringe (10) and needle (18) can be used and a shielding position where at least the tip of the needle (18) is covered to prevent accidental needle stick injuries, comprising a shield (11) slidably attached to the body of the syringe (10) that can be moved between retracted and shielding positions to at least shield the tip of the syringe needle (18) and locking means (12) comprising at least one forward facing resilient prong (15) located with respect to the syringe (10) and a projection (16) on the shield (11) whereby the projection (16) can deflect the prong (15) to pass over it, but abuts against the moveable end of the prong (15) to thereby prevent rearward movement of the shield (11).

Abstract: A syringe retraction arrangement including a retaining means (70) mounted on the syringe barrel to retain the syringe within a sleeve assembly (40) on retraction of the hypodermic needle into the sleeve assembly (40). The retaining means (70) includes at least one extension (76, 77), the extension (76, 77) extending outwardly in a radial direction and towards a needle end of the sleeve assembly (40) where he needle (45) resides and wherein the free end of the at least one extension (76, 77) engages an abutment (78, 79) in the sleeve assembly (40) with the abutment (78, 79) acting as a bearing surface for the at least one extension (76, 77) thereby retaining the syringe within the sleeve assembly (40) after retraction.

Abstract: An indicating device (100) for displaying temperature history of an object over time includes, a reservoir (40) of indicating material secured with respect to said object, the indicating material being solid below a predetermined temperature and liquid at or above this predetermined temperature; a wicking member (30) arranged with respect to the reservoir so that the indicating material is able to migrate from the reservoir through the wicking member to a peripheral portion spaced from the reservoir; and indicator means spaced from the reservoir so that migration of the indicating material to the indicator means indicates a predetermined temperature history; wherein said indicator means includes a barrier member (20) located on the wicking member and having a barrier region positioned between the reservoir and said peripheral portion of the wicking member and wherein said barrier member prevents viewing of the migration of the indicating material through the wicking member until it migrates past said barrier

Abstract: A syringe retraction arrangement adapted to automatically retract a syringe (2) into a container (40) upon full depression of a plunger (20) of the syringe into the syringe thereby avoiding the potential for needle stick injuries. The syringe (2) is resiliently biased to retract into the container and has a retaining arrangement to prevent it retracting and has release means for the retaining arrangement which are engaged upon complete depression of the plunger to operate the release means. The arrangement has a sleeve assembly (41, 42) to receive the syringe with an aperture (45) at one end of the sleeve assembly through which the hypodermic needle extends in use, a pair of ears (55) on the sleeve on the end remote from the aperture. The ears are adapted to engage the end of the syringe barrel (23) remote from the hypodermic needle and to release the syringe barrel by disengagement with the end of the barrel when the ears are spread apart.

Abstract: This invention relates to a syringe (10) and a sleeve (11) assembly wherein the needle (13) of the syringe (10) is retractable with respect to the sleeve (11). The sleeve (11) has an open end (18) and a closed end (19) with an aperture (20) through the closed end (19). A syringe (10) with a needle (13) located within the sleeve (11) is movable between a first position, in which the needle (13) is within the sleeve (11), and a second position where the needle (13) is located through the aperture (20) so that it protrudes from the closed end (19) of the sleeve (11). A biasing element (22) acts between the syringe (10) and the sleeve (11) and applies a retraction force to move the syringe (10) from the second position to the first position so as to withdraw the needle (13) from the closed end (19) of the sleeve (11). The invention allows automatic and failsafe retraction of the needle (13) once the syringe (10) and sleeve (11) assembly is discarded.
