Abstract: A method for cleaning and lubricating an injection sleeve and plunger tip during a fill and injection cycle in a cold chamber die casting machine, in which the plunger tip has an annular generally arcuate recess, lubricating nozzles, lubricating conduits, and scrap exhaust conduits. Pressurized air is released into the recess during the injection cycle and debris is exhausted through the scrap exhaust conduits. Upon completion of the injection cycle, the release of pressurized air into the recess is terminated. A mixture of pressurized air and lubricant is released through the recess onto the injection sleeve during the withdrawal cycle. Upon completion of the withdrawal cycle, release of the mixture of pressurized air and lubricant into the recess is terminated.

Abstract: In order to arbitrate competing requests made by master elements for shared resources in a data processing system in which the masters have controlled access to the resources through a communication bus, there is provided an arbitration unit coupled to the masters and to the resources through the communication bus. There is further provided logic structure in each master for generating and sending access request signals to the arbitration unit indicating that the master needs to direct, through the communication bus, a specified resource to perform an operation, the selected resource being identified by at last one of the access request signals. The arbitration unit, upon receiving the access request signal, arbitrates among competing access request signals, which may be concurrently received from a plurality of masters, according to predetermined priority criteria.

Abstract: A die-casting machine is described which includes at least one cylinder/piston assembly. Each assembly has main, ejector and core pistons and cylinders. The main cylinder is stationary and holds a piston which reciprocates to bring the molds together for metal injection or apart for releasing a die casting. A portion of the interior of the main piston constitutes an ejector cylinder having an ejector piston and a portion of the interior of the ejector piston constitutes a core cylinder having a core piston. The present invention is more compact and less complex than conventional die-casting machines.
