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: A metallic spray nozzle having a counterbore from one side thereof into which an insert to control the spray is located and retained by way of a retaining lip formed by deformation of the outer periphery of the counterbore. This deformation can be toward an axis of the nozzle or, alternatively, this deformation can subsequently direct the tip of the periphery outwards at its extremity such that flow into the counterbore is smooth. An O-ring or other sealing membrane is provided between a locating shoulder in the nozzle body and the insert, and an insert shield between the insert and the retaining lip.

Abstract: A manually constructed nozzle assembly includes a first component in a fixed engagement with a spray pipe. The first component is a base component and has a device for manual engagement with a second component, which is a cap component, so that a shower disc is able to be compressively held between the first and second components. Each of the first and second components has a central aperture, so that a shower nipple is able to extend into the spray pipe, when assembled.

Abstract: A system, method and apparatus for locating and accessing information resources in a distributed information network is disclosed. When an end user desires to retrieve an ID for a particular profile associated with a resource, a client program (resident on a client computer) sends a an ID request in the form of an HTTP request to an ID authority server computer. In response to the ID request, the ID authority server computer returns a URL of an ID registry server computer corresponding to the requested profile type. The client program then sends a query based upon the returned domain name to the ID registry server. The ID registry server, in turn, returns a URL of an ID host server computer associated with the requested ID so, in one implementation, the client can invoke a program that is a superset of the domain name. Once the client program has the location of the ID host server computer, the client program sends a request to the identified ID host server computer.

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.
