Abstract: A valve (10) is disclosed. The valve (10) has an inclined valve seat (14) defining a fluid aperture (18), and a valve head (20) for contact with the valve seat (14) for closure of the fluid aperture (18). A lever arm (22) is attached to the valve head (20). There are biasing means (32) operatively coupled to the lever (22) arm for urging the valve head (20) into contact with the valve seat (14), the biasing means (32) being arranged to provide decreased biasing on opening of the valve head (20) relative to the fluid aperture (18).

Abstract: The present invention provides a valve (10) comprising a mounting member (12) for mounting of the valve. The valve includes a collapsible aperture (20) which in an open condition allows for flow of a fluid in a forward direction through the valve whilst in a closed condition prevents flow of fluid in a reverse direction. In one form of the valve, the valve element is connected to the mounting member (12) via an isolation zone (22) that reduces likelihood of the collapsible aperture moving to an open condition under impact. In another form of the valve, the valve element is configured to provide opening of the collapsible aperture on application of a predetermined force to the mounting member. In a final form of the valve, the valve comprises a sports ball valve having a collapsible aperture which is opened by fluid pressure alone.

Abstract: A hyperbaric capsule (10) has a base (12) forming a seat (14) that can be enclosed by an elongate oval canopy (16) having a large transparent window (18) formed therein. The bottom of the front of the canopy (16) is pivotally attached to the front of the base (12) by a hinge assembly (22) and can be locked in the closed position on the base by a plurality of latches (50a-50d) that are conjointly operated by an external lever (54) and an internal lever (56, not shown in FIG. 1). The weight of the canopy upon opening is borne by a pair of side gas or spring struts (24).

Abstract: A water skimmer vessel has two hulls (12, 14) between which a debris collection net or basket-like catcher (22) is arranged. Hinged flaps (68) are provided at each end of the catcher and operate to allow inflow but block outflow of debris from the catcher. Each hull of the vessel is equiped with amoter covered by a guard (28). The vessel may move in either direction and is equipped with sensors (30) on each hulll for effecting the turning and reversing of the vessel upon contact with pool skimmer box inlet (206) and the vessel can be controlled to enter the dock and permit the contents of the catcher to be discharged into the current of pool water flowing into the skimmer box.

Abstract: Disclosed is an outdoor cooking apparatus including a grill having a lower portion and an upper portion. The upper portion of the grill has a metal curved top surface, and is hinged to the lower portion of the grill. The lower portion of the grill is releasably mounted to a support frame, which is in turn releasably mounted to the rearward portion of a vehicle. A metal cover, which contains printed indicia thereon, releasably mounts to the upper portion of the grill. The printed indicia cover overlies the top surface of the upper portion of the grill, and is substantially parallel to the top surface of the upper portion of the grill.

Abstract: A wall frame structure consisting of wall plates and wall studs, which are formed of metal sheet, with the wall plate being provided with projections to engage the stud to aid in securing the stud in position, and the stud being reinforced by transversely extending ribs and reinforced apertures. A reinforcing bracket surrounds the stud and aids in securing the stud to the wall plate. There is further provided reinforcing clips which extend between the flanges of the stud to inhibit transverse movement of the flanges relative to each other, under loading.
