Patent GB-2298463-A (GB)
Title: Grease Gun
Inventor: MARTIN GERALD LAWRENCE
IPC: F04B9/127
Filed: 1995-03-01
Abstract: A grease gun comprises a cylinder 2 with holes 4 through which grease is sucked into the cylinder from a reservoir 7 during a spring powered suction stroke of a piston 1. To perform a delivery stroke, pressurised fluid is applied to the piston through an orifice 8 whereby the piston moves to cover the holes and eject grease through a pipe 9. Due to the spread of the holes 4 in the base 10 the grease is drawn down the reservoir 7 in an even manner making the grease level easily visible. The stroke of the piston 1 causes an initial increases in pressure in the cylinder, the pressure being further increased by the action of a cavity 6 in the piston covering an end plug 3. It is possible to pump a known quantity of grease and a variety of other viscous and semi-viscous fluids.

Title: Destruction of spent aluminium smelting carbon electrodes in molten salt
Inventor: SCHNITTGRUND GARY DENNIS
IPC: A62D101/45
Filed: 1995-03-10
Abstract: A process for destruction of spent aluminum smelting carbon anodes and carbon block cathodes which are contaminated with cryolite, Na3AlF6, comprises introducing such spent carbon electrodes into a molten salt bath, e.g. molten sodium carbonate, at elevated temperature, e.g. about 900 DEG C, together with air or oxygen, and catalytically oxidizing and destroying the spent carbon anodes in such molten bath, and recovering an off-gas containing chiefly CO2 and retaining spent salts including sodium fluoride and sodium aluminate in the molten salt bath. The molten salt bath also destroys any small amount of NaCN which may also be present in the cryolite contaminant, and converts such NaCN to nitrogen and CO2, which are released in the off-gas. <IMAGE>

Title: Mixtures of hexahydrotriazines useful as H2S SCAVENGERS
Inventor: RIVERS GORDON T
IPC: C07D251/04
Filed: 1993-09-30
Abstract: A mixture of amines made by reacting an amine compound with an aldehyde compound has been found to reduce the levels of H2S in liquid or gaseous hydrocarbon streams. At least one of the compounds must have an alkoxyalkylene radical. In one embodiment of the invention, the mixture of amines contains at least one hexahydrotriazine compound of formula (i) where R<1>, R<2>, R<3>, R<4>, R<5> and R<6> are independently selected from the group consisting of hydrogen and an alkyl radical, including substituted alkyl radicals, of 1 to 5 carbon atoms; where at least one of the groups is an alkoxyalkylene group. In another embodiment of the invention, the amine mixture may contain other by products, such as the monomers which make up the hexahydrotriazine, with or without the hexahydrotriazine being present. These materials are selective to the reduction of H2S levels in hydrocarbon or aqueous streams in the presence of CO2 which does not compromise their performance. <IMAGE>

Patent GB-2301786-A (GB)
Title: Applying two-part mixtures of materials
Inventor: NEEDHAM DAVID MARK
IPC: B05B7/32
Filed: 1996-06-04
Abstract: Two materials, especially ones which react together, are applied by means of a spraying device 26. Each material is supplied from its own tank 48, 50 via a three-way valve 25, 26 to a mixer upstream of the sprayer. To avoid wastage when the spray-gun trigger is released, the valves 25, 26 are automatically switched to positions where each material is recirculated to its respective reservoir. The returned materials flow through back-pressure valves 47, 49 which may be adjusted so that the pressure drop in each fluid line is the same during recirculation as it is when spraying. This gives "steady-state" conditions throughout spraying.

Title: Windshield wiper system
Inventor: OGAWA TOMOYUKI
IPC: B60S1/48
Filed: 1996-11-29
Abstract: In a vehicle windscreen wiper control system an auto stop switch AS and an energisation retaining circuit 3 ensure that power to the motor M is maintained so that the wiper comes to rest at a desired position, no matter where in the cycle the on signal is terminated. The auto stop switch AS maintains the supply of power to the motor when the ON signal is terminated when the auto stop switch AS is in the drive position and the energisation retaining circuit maintains the supply of power if the ON signal is terminated with the auto stop switch AS in the brake position. Thus power to the motor is always terminated when the auto stop switch AS changes from the drive position to the braking position so that the degree of overrunning of the motor is fixed, irrespective of the time of termination of the ON signal.

Title: Method and apparatus for cleaning workpiece surfaces and monitoring probes during workpiece processing
Inventor: HOLZAPFEL PAUL
IPC: B24B49/00
Filed: 1998-02-06
Abstract: The present invention provides methods and apparatus which permit the in-process, in situ, substantially real time measurement of the actual thickness of a surface layer of a workpiece, e.g., a semiconductor wafer. A probe is disposed proximate the outer perimeter of a polishing pad on a CMP table such that the probe establishes optical contact with the wafer surface as a portion of the wafer extends beyond the outer perimeter of the polishing pad. A reflected signal received by the probe is analyzed to calculate the thickness of the surface layer. Alternatively, the reflective characteristics of the semiconductor layers may effect the nature of the reflected signal; changes in the reflected signal can be detected to indicate when a metallic layer has been removed from an oxide layer. In accordance with another aspect of the present invention, a nozzle assembly having a plurality of fluid outlets may be provided to apply a stream of deionized water at the surface under inspection to thereby remove excess slurry and debris from the local region of the workpiece being inspected. A second fluid nozzle may be provided to apply a stream of deionized water to the tip of the probe tip to thereby clean the probe tip between endpoint detection cycles. The nozzle assembly may also include a third fluid nozzle for applying a stream of nitrogen gas to thereby deflect debris away from the probe tip during the endpoint detection procedure and a fourth fluid nozzle for applying a stream of nitrogen gas to thereby remove water and debris from the probe tip during the endpoint detection procedure.
