Title: Afterburning prevention device for an internal combustion engine
IPC: F02M23/00
Filed: 1974-12-10
Abstract: A three-valve prechamber internal combustion engine is provided with a conduit through which atmospheric air may be drawn into the intake passage leading to the prechamber.

Title: Method of duplicating plastics information carriers
IPC: G11B7/2539
Filed: 1978-03-03
Abstract: The invention relates to a method of reproducing plastics record carriers, in particular duplicating video records. According to the invention, a metal die is used which is provided with a thin-liquid molding resin of a particular composition which can be polymerized by radiation. A radiation-pervious substrate which is manufactured from synthetic material, for example polymethylmethacrylate, is provided on the molding resin. The molding resin is exposed to light via the substrate after which the cured molding resin together with the substrate connected thereto is removed from the die. The molding resin used in the process comprises low-molecular monomers or oligomers which contain on an average 25-70% by weight of hydrocarbon groups and/or phenyl groups. The molding resin is aprotic and has a functionality as regards unsaturatedness which is between the values 2 and 6. A suitable molding resin contains mono-, tri- or tetra esters of acylic acid. The molding resin preferably has a swelling capacity with respect to the substrate and for that purpose preferably comprises a vinylmonomer. The metal die used in the method preferably is a quite flat die which is obtained by providing the master disk which is a flat glass plate with information track with a nickel layer, gluing hereon a flat stiffening plate and then removing the master disk. The resulting father disk may be used as a die. Alternatively, further metal copies may be made herefrom which are provided in a simpler manner with a flat stiffening plate. The invention also extends to the molding resin, substrate and die used in the method, as well as to the resulting plastics record carriers.

Title: Multiple speed ink jet printer.
IPC: B41J2/485
Filed: 1979-11-07
Abstract: Disclosed is a multi speed ink jet printer in which alternate vertical scans of the ink stream may be omitted or alternate dots horizontally may be omitted or a combination of the two.

Title: Improved system for interrupt arbitration.
IPC: G06F3/00
Filed: 1981-10-19
Abstract: A data processing system in which a unit needing to be serviced by a processor first requests an interrupt and, after the interrupt is granted by the processor, requests access to a system bus to transfer interrupt information as it normally would transfer other information. The interrupting unit must wait for other units having higher priority to transfer information, usually memory information over the bus, before it can access the bus to transfer its interrupting information. This permits transfers of information having higher priority to occur before the transfer of the interrupt information is transferred.
