Patent EP-0282046-A2 (EP)
Inventor: SULZER GERD DR
IPC: B23F23/12
Filed: 1988-03-09
Abstract: The machine tool has a tool spindle which carries a grinding worm, can be driven rotationally while coupled in a rolling-contact manner to the work carrier and is mounted in a reciprocating tool-slide arrangement by means of which a working stroke and a following return stroke can be imparted to the grinding worm relative to the workpiece. A polishing worm is arranged on the tool spindle in such a way as to be axially offset relative to the grinding worm, and the return stroke of the tool-slide arrangement can be performed as a working stroke of the polishing worm while maintaining the rolling-contact coupling so that renewed synchronisation between tool and workpiece is dispensed with. Furthermore, a tool is described which represents a combination of grinding and polishing worm and is used in the above machine.

Abstract: A method and an apparatus for emulating a console at a graphics workstation terminal uses a second central processing unit to perform the console emulation. A windowing system operating on a first central processing unit interfaces with the operation of the console from the second central processing unit to provide non-­destructive console emulation at the workstation terminal. The windowing system maintains a separate console window that the second central processing unit can access transparently to the other windows. The first or host cpu can still perform graphics functions while the second cpu operates the console.

Abstract: In a satellite communications system, satellite channels are divided into groups of successively adjacent channels which are covered by a range of frequency drifts caused by a satellite transponder and the channels of each group are assigned unique words of different bit patterns. Modulation systems of an earth station are associated respectively with demodulation system (7, 8) of distant earth station via the respective satellite channels. A unique word is transmitted from each modulation system together with an information signal and received by an associated demodulation system of the distant earth station. A variable frequency carrier is synthesized in the demodulation system to demodulate the received signal to recover the information signal and the unique word. The recovered unique word is used to establish the frame start timing and the variable frequency carrier is controlled in response to the unique word to tune in the demodulation system to the desired satellite channel.

Abstract: In a pressure swing adsorption system used to recover an oil-soluble solvent, monomer or hydrocarbon vapor such as 1,1,1-trichloroethane or styrene from a gaseous stream such as air, an oil-sealed vacuum pump may be used without substantial absorption of vapor into the oil if the oil in the pump is heated to a temperature substantially above the dew point of vapor in the gas stream leaving the pumps. Prior to this invention, oil-sealed vacuum pumps cannot be used to recover oil-soluble compounds because the vapor dissolves in the oil as the desorbed vapor and backpurge gas pass through the pumps. The thinning of the oil hurts the lubrication and seal within the pump and floods the pump.
