Abstract: A static axial seal gland (100, 100) formed in relief in a substrate (31, 52) and having an inner sidewall (32, 53), an outer sidewall (33, 54) and a floor (34, 55) extending between the inner sidewall (32, 53) and the outer sidewall, one or both of the inner sidewall (32, 53) and the outer sidewall (32, 53) being concavely-profiled in radial section along a major portion of its depth to define a projecting lip (35, 56) proximal a land of the substrate (31, 52), the gland (100, 100?) being fitted with an elastomeric O-ring (39, 59) which is located and retained by interference with the projecting lip (35, 56), either under tension on the inner sidewall (32, 53) or in compression against the outer sidewall (33, 54).

Abstract: A wear part includes at least one wear component made from abrasion-resistant material and an upper seal groove around a central aperture on the upper face of the wear part. The upper seal groove is adapted to receive an axially compressible seal. A spray nozzle assembly includes at least one wear part made from a hard and abrasion-resistant material and a protective housing made from a strong and resilient material and having a downstream chamber adapted to receive one or more of the wear parts in releasably trapped relationship, the downstream chamber having a wall including a post defined by a slot in the downstream chamber wall either side of the post, the post including an inwardly extending protuberance at or near its end and adapted to prevent the wear part from escaping from the downstream chamber.

Abstract: A spray nozzle assembly (10) comprising a cap (30) which houses an inner assembly of nozzle inserts (40). The cap (30) is threadably engaged by complementary threads (31, 21) to a nozzle body (20). The nozzle body (20) and the cap (30) are therefore able to be mated in a controllable axially compressive relationship in which the threadable connection enables a large amount of finely controlled axial tensile or compressive force to be applied in either moving the cap (30) and nozzle body towards each other or away. It should be noted, however, that seat (70) restrict the extent of axial travel of the screwable parts (20, 30, 40) relative to and towards each other. This facility enables strong unwanted adhesive forces of glue-like or set flowable material to be broken so that the cap (30), insert assembly (40) and nozzle body (20) can be moved apart for servicing.

Abstract: The invention is a sealing means in a spray nozzle assembly which includes the provision of a groove adapted to at least partially accommodate a sealing means such as an O-ring in the surface of an upper face of an orifice disc said face being directed towards a lower face of an inner periphery of a nozzle cap.

Abstract: A blow off cap and nozzle apparatus includes a nozzle having a tip with an aperture covered with a sealing membrane held in position over the nozzle aperture by a retaining device, so that a seal is provided for preventing ingress of contaminants into the nozzle when not in use, and the sealing membrane becomes dislodged from the nozzle when use of the nozzle commences.

Abstract: The invention is a centrifugal brake device that is a speed control means for spring motor hose and cable reels. This brake device is mounted to a shaft of a hub associated with the reel, such that the device controls the reel rotation speed.

Abstract: A rotating spray nozzle for use in cleaning containers having a spray head on a shaft, an element for passing liquid both to the exterior of the spray head to cause rotation thereof and for the delivery of liquid in annular streams, liquid passing to the spray head through the shaft and having an hydraulic bearing therefor, the liquid after passing from the spray head occupying which would be a void as far as washing is concerned. The spray head is also moveable axially relative to the shaft, a spring holding the spray head away from the bottom of the shaft when there is no pressure passing therethrough, the pressure of the liquid moving the spray head to the bottom of the shaft, the arrangement providing a manner whereby foreign material can be removed from between the spray head and the shaft as, by reducing the pressure, the space between these can be increased, thus permitting ready flushing of the foreign material.
