Abstract: A lock, including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, wherein the knob release mechanism includes a damper with a gear that is slidably received within a set of grooves located in the retractable knob, and wherein the gear prevents rotation of the retractable knob unless it is in an extended position.

Abstract: A gas flotation tank is provided that includes a series of adjacent chambers which impart a rotational current therein. Each chamber is separated from a skim oil trough by a skimming weir. Each chamber comprises an alternating fluid communication device between adjacent chambers allowing fluid communication between adjacent chambers in the form of a communication port in the dividing wall between adjacent chambers and a chamber outlet in conjunction with a perforated plate and the outlet is positioned in fluid communication with the final chamber. An optional coalescing media may be positioned in or proximate the communication port to absorb or coalesce contaminants as they pass therethrough.

Abstract: A nozzle is disclosed for use within a filter for inputting a jetting stream into the filter media to clean the filter media. The nozzle comprises an inlet for communication with a jetting stream source, and a plurality of plates stacked parallel and abutting one another. The plurality of plates comprises at least a top plate and a bottom plate, one of the plates having an aperture through the center thereof for receiving the jetting stream, wherein between adjacent plates at least one space is provided extending from the outside edge of the plates to the interior of plates and in fluid communication with the aperture for channeling the jetting stream radially outward from and substantially parallel with the longitudinal plane of the plate.

Abstract: A method for modifying the surface of an architectural finish for a metal structure that increases its surface energy to almost double the surface energy obtained by the methods currently being performed, particularly in the curtain wall industry. Specifically, a flame plasma treatment process is applied to the surface of the finish in accordance with the disclosed principles to achieve the disclosed results.

Abstract: A separation tank for separating a contaminant from a contaminated fluid. A series of juxtaposed interconnected chambers having a series of baffles therein provide a revolving flow of fluid in each chamber to maximize distance for which contaminants travel to separate from the fluid. The interconnected chambers may be juxtaposed in end-to-end relation or in side-by-each configuration.

Abstract: There is described a method, apparatus and shaping tool for shaping a workpiece. The tool comprises a flexible support surface on which are mounted a number of rigid pellets (84) carrying abrasive material. The tool is driven, in contact with the workpiece surface (S), to perform a ductile grinding operation which results in a finished surface of reduced roughness as compared to conventional grinding operations, while achieving significantly higher material removal rates than comparable ultra-precision grinding techniques. A procedure for preparing the tool for operation by conditioning the tool against a conditioning surface is also described. An exemplary application for the method and apparatus is in the preparation of moulds for moulding curved glass components for use in display screens, in which process a silicon carbide mould cavity surface is shaped using the method to produce a mould cavity surface with a smooth surface finish.

Abstract: A material spill prevention system with feed location sensing system to reduce the possibility of material spillage relative to the film being utilized for bag formation. The material spill prevention system monitors whether there is a proper film feed situation and, if not, precludes the release of material from the dispenser as in by precluding a flow controller opening and the release of material to the bag intended to receive the release chemical (e.g., a foam packaging bag). The prevention system is applicable to a variety of film feed arrangements as in a C-fold film drawn by a nip roller arrangement from a roll source with the dispenser mechanism positioned intermediate the nip and film source relative to film travel. An embodiment of the spill prevention system also features an absolute position transducer for monitoring position of a flow controller which controls output of material from the dispenser.
