Patent AU-727394-B2 (AU)
Title: High speed grinding wheel
Inventor: WU MIANXUE
IPC: B24D5/04
Filed: 1998-09-25
Granted: 2000-12-14
Abstract: A method of obtaining superabrasive grinding performance from tools employing less expensive, non-superabrasive conventional abrasive grain involves operating the conventional abrasive tool at ultra high tangential contact speed, (that is at least about 125 m/s). Such ultra high operating speeds can be achieved with segmented abrasive grinding wheels having segments formed from vitreous or resin bonded particles of aluminum oxide, silicon oxide, iron oxide, molybdenum oxide, vanadium oxide, tungsten carbide, silicon carbide and the like. The abrasive segments can be cemented to the core of the tool with an adhesive such as epoxy cement. Abrasive segments can be made to a significantly greater depth than traditional superabrasive-bearing segments, and consequently, should provide long life as well as high performance. Additionally, conventional abrasive segments are easier to true and dress and to make into intricate profiles for grinding complex shaped work pieces.

Title: Movement sensor for contactless travel path hoist - has illuminating and reflected rays passing through single partly transparent mirror
IPC: B64C27/00
Filed: 1969-05-31
Abstract: The contactless travel path measuring equipment is for a propeller test stand, reflective balls being mounted on the blades. As the blades pass the measuring unit, rays reflected from the balls sweep over a measuring grating comprising alternate transparent and non-transparent strips, passing through it to a photo-electron multiplier behind. Illumination and reflection take place on a common axis, the balls (3) being illuminated via a partly-transparent mirror (7), through which the reflected rays also pass. These rays can also pass through a lens unit (4) of variable focal length. Between the grating (8) and the multiplier (10) there can be a light conductor composed of fibres (9).

IPC: B65H9/00
Filed: 1983-03-11
Abstract: A sheet feeding assembly for a printing press including a feed table having a set of front stops and which is inclined downwardly so that a sheet travels toward the front edge of the table where it is temporarily retained in registered position. A port connected to a source of compressed air extends through the table at a position spaced from the front edge of the table. A rear feed plate is seated on the table upstream of the port and a front feed plate is seated on the table downstream of the port, the plates being substantially coplanar with their respective front and rear edges in proximity and uniformly spaced with respect to one another. The front edge portion of the rear feed plate is undercut to form an overhang which defines a transversely extending air conducting cavity which overlaps the port so that an air blast is directed at an angle upwardly and forwardly of the table to lubricate the passing sheet and to urge the sheet in the direction of the front stop. The rear plate is adjustably shiftable to vary the spacing between the plates thereby to vary the rate of discharge of the air. A manually adjustable cam elevates the front edge of the rear plate to a variably upraised position thereby to vary the angle of discharge of the air against the sheet.

Patent JP-2547563-B2 (JP)
IPC: H03L7/08
Filed: 1987-03-27
Granted: 1996-10-23
Abstract: As used in a digital television receiver, the invention is associated with a first phase locked loop which develops a sampling clock signal that is locked to the horizontal line synchronizing signal components of a composite video signal. A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal. This digital signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signals into I and Q color difference signals. To compensate for frequency instability in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop (300) develops an output signal which is phase locked to a reference signal generated by a crystal controlled oscillator (310). Control signals (C') from the third phase locked loop are applied (328) to the second phase locked loop to substantially compensate for frequency instabilities in the regenerated subcarrier signal that are induced by the clock signals.

Filed: 1994-03-22
Granted: 1997-07-16
Abstract: A system management mode address correction system for a computer provides correct address values on the address bus when the computer is in system management mode. Conventionally, bit 20 of the microprocessor's address outputs may be masked by asserting the FORCE A20 signal. The computer system also operates in a system management mode, which requires all of the address bits to be available for proper access to the system management interrupt vector. When the computer is in system management mode, the computer's microprocessor asserts a system management interrupt active (SMIACT*) signal. This signal is provided to a circuit which also receives the FORCE A20 signal. While the SMIACT signal is deactivated, the control circuit provides the true FORCE A20 signal to the computer system. When an SMI occurs, the SMIACT signal is activated and the FORCE A20 signal is disabled. As a result, the address generated by the microprocessor is asserted on the address bus. <IMAGE>

Abstract: Tyres are retreaded by using a pre-vulcanised tread and an uncured layer of rubber between this and the carcass, the rubber being cured by applying high frequency from above the tread. This rubber is also locally heated at or near its edges by extra heating outside the tyre. - Specifically the same h/f generator is used to heat both the outermost area of the rubber adhesive between carcass and tread and also the edges area of the rubber. The h/f energy is therefore more efficiently utilised, and the edge application is adjusted so that it at least equals the heat losses from those areas. The whole cure of the adhesive rubber layer is thus made more effective. As an alternative to using high loss factor rubber for h/f heating the edges, e.g. a ring of high loss factor material can be applied to each edge area and thus heat up the rubber edges externally. - Method eliminates the usual problem of cooling at the edges when the assembly is cured in an autoclave contg. unheated pressurised air.(0/8)
