Abstract: A door closer has a housing for connection to a door and a drive spindle (10) coupled to the door. As the door moves the spindle (10) and housing (11) rotate relative to one another. The relative movement is translated by a piston and cam mechanism (21, 22) into a force that is used to separate a pair of magnets (28). The magnetic attraction of the magnet pairs (28) serves as a force to resist opening of the door and biases the door from an open to a closed position. At least one first magnet is coupled to the drive member and at least one second magnet (32) coupled to the housing. The magnets are arranged in the housing with their opposite poles facing one another such that there is a magnetic force of attraction between them. At least one further biasing spring (36) may be provided to provide a biasing force after the magnetic force has diminished by separation of the magnets.

Abstract: Latch assembly for a vehicle door 10 (FIG. 1) hinged at its leading edge has an L-shaped housing plate 20 to be secured in the trailing inside edge comer of the door and carrying latch mechanism. Inner skin 14 of the door is cut away to admit a striker 18 into a mouth of the plate for engagement by the mechanism to keep the door shut. A projecting abutment rib 28 of the plate adjacent the mouth prevents or resists rearward displacement of the trailing edge of skin 14 which could otherwise obstruct the mouth in the event of impact damage to the door.

Abstract: A passenger vehicle door latch assembly (10) includes a cam e.g. (90a) rotating in common with a latching claw (30) which is retained by a pawl (34) at first safety and fully closed positions of an associated door, the shaping of the cam controlling operation of locking mechanism of the assembly. Lobes, e.g. (92a,92b) on the cam co-act to shift a release lever (64) of the mechanism back to an active position at which it will free the pawl by operation of a door handle for opening of the door even if it has previously been set to a disabled condition at which the door would otherwise be locked so as to prevent inadvertent slam locking of the door Different cams (90a, 90b, 90c or 90d) may be substituted in an otherwise common assembly to provide a selection of logic sequences of self-cancelling or prevention of locking operations.

Abstract: A reinforcement module for a vehicle door comprises a plurality of elongate reinforcement members (1) and a plurality of connectors (2a, 2b and 2c). Each connector (2a, 2b and 2c) is engageable with the free end portions of at least two of the elongate reinforcement members (1) to connect those elongate reinforcement members together. The arrangement is such that at least one of the elongate reinforcement members (1) extends generally transversely with respect to at least one other elongate reinforcement member.

Abstract: A vehicle door latch mechanism including safety structural components. The latch mechanism includes a latch bolt having a closed condition capable of retaining a striker and an open condition capable of releasing the striker, a pawl which in use releasably secures the latch bolt in its closed condition, and a retention plate. The retention plate includes at least one mouth which co-operates with a retention means to releasably retain the striker in the mouth, at least one pivot pin hole defining a pivot pin hole surface for a pivot pin which is secured to the retention plate in the hole or is pivotally mounted in the hole, and at least one fixing means for fixing a latch mechanism in its operating position. The latch bolt, pawl and retention plate co-operate in use to releasably retain a striker in which at least one of the said safety critical structural components is made from a plurality of structural laminations of material.

Abstract: A heat exchanger for aircraft electronics. The present invention provides a plurality of reflux coolers wherein each reflux cooler is primarily dedicated to cooling a specific electronic component, such as one phase of a multiphase device. The reflux coolers are undersized to adequately cool the individual phases to which each are dedicated, but are interconnected and cross-linked such that the heat dissipation demand is shared amongst the plurality of reflux coolers. Moreover, the heat pipes interconnecting the reflux coolers can be provided with additional surface area in the form of fins to further augment the heat dissipation capacity of the system. Therefore, in the event a single reflux cooler is damaged, for example, during military engagement, the remaining reflux coolers are able to share the load primarily designed to be dissipated by the damaged reflux cooler.

Abstract: A compact, rugged and light weight condenser structure for a heat exchange system, preferably fabricated in layers and incorporating a jet fin structure for heat exchange with a single phase coolant fluid and tapered passages to maintain relatively constant vapor flow velocity and a consistent, high efficiency flow regime in a refrigerant fluid including vapor and liquid phases. Layered construction permits economical fabrication of the condenser in a plurality of configurations and heat exchange capacities. Tapered configuration of the refrigerant passages, together with the consistent distribution of jet fin heat exchange to the coolant allows a flow regime to be maintained which is highly tolerant of variation in the direction and force of acceleration forces on the condenser. Accordingly, a condenser capable of highly consistent heat exchange performance over a wide range of acceleration conditions is provided.
