Abstract: A tooling fixture for supporting a workpiece, comprising: a body including a surface over which a workpiece is in use supported and a plurality of bores therein; a plurality of supporting elements (12) for supporting the workpiece, each slideably disposed in a respective one of the bores such as to be extendable from the surface of the body; at least one fluid reservoir (9) operably in fluid communication with the supporting elements such as to cause sliding of ones of the supporting elements on displacement of the fluid in the at least one fluid reservoir, and fluid control means (53) for displacing the fluid in the at least one reservoir such as to cause the supporting elements to be extended to a supporting position in contact with the workpiece and locking the supporting elements in the supporting position.

Abstract: A workpiece support device comprises an array of rods in columns and rows with free ends of the rods forming, a support surface, in which support surface recesses can be created by selectively retracting individual ones of the rods. Each rod is coupled to a respective piston within a respective cylinder and each cylinder has an upper connection for medium pressure, a lower connection for high pressure and a middle connection for low pressure. A trigger piston is provided in a cylinder below the piston. The rod can be caused to extend from the cylinder by applying low pressure to the connection to press the trigger piston downwardly to close the high pressure connection. Such low pressure passes around the lip of a lip seal on the trigger piston and through a connection pressurises the underside of the piston to raise the piston and release it from pressing the trigger piston downwardly. Subsequently pressurising the connections and causes the differential pressure to force the piston upwardly.

Abstract: An adapter for converting an existing under screen cleaning apparatus from one which uses a solvent to a solventless under screen cleaning apparatus. The adapter fits within the vacuum channel and between the blades of a known under screen cleaning apparatus. The adapter extends above the top edges of the blades and provides a top surface with at least three lands and a plurality of slots. An interior hole within the adapter connects the slots with a vacuum outlet of the vacuum channel. Optionally, suction is applied to the slots by pumping air from the vacuum outlet.
