Title: Bipolar endoscopic surgical scissor instrument
Inventor: SLATER CHARLES R
IPC: A61B18/12
Filed: 1996-01-24
Abstract: Endoscopic bipolar scissor blades (26, 28) are provided and include a pair of metallic electrically conductive blades each having a cutting edge (26a, 28a) and an adjacent shearing surface (26f, 28f), where at least one of the blades is partially covered with an electrically insulating ceramic material (29). The partial ceramic covering covers substantially the entire cutting edge of the blade and a relatively small portion of its shearing surface adjacent to the cutting edge. If desired, a larger angled portion (29b, 28f) of the shearing surface may be covered. The ceramic covering is applied by either masking the portion of the blade which is not to be covered and by spraying the masked blade with a ceramic, or by bonding a thin ceramic member to the blade. In another embodiment of the invention, a scissor blade (126, 128) is provided with an insert receiving channel groove (128g) on a portion of its shearing surface adjacent to its cutting edge. A ceramic insert (129) having a groove engaging tongue portion (129c) is inserted into the channel groove (128g) and forms a ceramic cutting edge on the metallic blade. An endoscopic bipolar cautery scissors instrument (10) which utilizes the partially covered blades of the invention is also described.

Title: Water purification systems
Inventor: REID RANDOLPH EUAN IRVINE
IPC: C02F1/00
Filed: 1996-03-15
Abstract: A water system is controlled (i.e. has its contents purified) by an ion supply unit, fed directly from the mains supply (15) to the water system and generating ion-laden water (concentrate) which is then injected (via 16) into the water system as required. The ion supply unit comprises a tank (26A), an ioniser (32A), and a pump (33A) which circulates water between the tank and the ioniser. The concentrate is injected into the water system, as water is drawn from the system or at suitable intervals as water circulates in the system. If the system does not use enough water to require replenishment at a rate which can incorporate the required amount of concentrate, a small amount of water can be drained off. Alternatively, the ion supply unit may comprise a reservoir which can be refilled with concentrate generated at and supplied from a central station; the concentrate can be stabilized by acidifying it with citric acid at a pH of 5.5.

Title: Process for treatment of residues which arise in industrial processes and in waste incineration
Inventor: GRAUWILLER MARKUS
IPC: C22B21/02
Filed: 1996-04-15
Abstract: Residues which arise from industrial processes and the burning of rubbish and contain heavy metals and/or heavy metal compunds are subjected to a two-stage reduction process providing re-usable metal and silicon-containing alloys. In a first reduction stage the compounds of silicon and metals having a greater normal potential than silicon are reduced using carbon or carbon-generating agents as reducing agents. After the reduced metals have been separated, the residue obtained, containing aluminium in oxidised form, is transferred to a molten salt bath which is subject to molten electrolysis in a second reduction stage yielding molten aluminium and silicon. The process is particularly suitable for filter residues from rubbish incineration plants.

Title: Ultrasonic skiver for unvulcanized rubber material
Inventor: FOSTER MICHAEL J
IPC: B26D7/14
Filed: 1998-03-20
Abstract: A skiver device is comprises of an ultrasonic knife and its holder, an upper floating roller assembly with a material lead-in device which guides the material to the knife blade, a roller anvil assembly with material lead-in and support rollers providing support of the underside of the material during cutting, an upper material separation device and a lower material separation device, which cooperate to keep apart the edge of the material supply roll and the edge of the severed strip as the cut progresses. These elements are supported from a traversing carriage which moves along a rail supported transversely with respect to a path along which a web of uncured rubber material is guided as the material is fed from a supply roll. The rail may extend at a predetermined angle to the web path so as to make a diagonal cut across the web material, and the knife is supported to cut the web material at an acute angle to the surfaces of such material, e.g. a skive type of cut. The skiver device incorporates the roller anvil assembly and a floating roller assembly, with freely independently rotatable arrays of rollers supported in close association with a skiver knife (preferably an ultrasonically excited knife), to control closely the positioning of the uncured rubber material from which the skiver knife will serve strips of predetermined width, and to provide separation devices which keep the edges of material apart as the severing action proceeds.

IPC: A47B83/00
Filed: 1998-06-03
Abstract: An office furniture system of free standing furniture elements which can be linked to each other comprises a modular desk unit and a modular storage unit.  The modular storage unit occupies the same floor footprint as a rectangular desk unit. The separate storage unit enhances the storage capacity of an office layout since the mounting of drawers and shelves are not limited by the desk unit configuration. The storage unit has compatible lay-in wiring trays, accepts compatible modular power components and accepts the same privacy partition panels and other accessories as are mounted to the desk units. When the desk unit and the storage unit are linked into an integrated office design, a continuous pathway is provided for the electrical, communication and data wiring required for the office system. Power cables are physically separated from the data and communication wires. Since the vertical space above the wiring trays remains accessible, cabling can be easily routed at any time through the system, enhancing office system expansion and design.
