Filed: 1996-03-01
Abstract: A casting method is disclosed in which a resin core  is fabricated by  using a resin which maintains  a  mechanical strength  satisfying  a shape accuracy required for  a  cast product until solidification of molten metal in contact with the  core  and  is  softened when  heated  beyond  the  core temperature  at which the molten metal in contact  with  the core was solidified.  The removal of the resin core from the cast product after the cast product containing the core from a die, includes a step of forcedly cooling the cast  product containing  the core down to a predetermined temperature  at which  the resin core can be removed from the  cast  product without being broken apart by pulling one of its ends, and a step   of   withdrawing  the  core  at   the   predetermined temperature  from  the  cast product  having  been  forcedly cooled down.  It is thus possible to cool the core down to a predetermined  temperature  suited for  the  withdrawal  and preclude  the  inconvenience that the core being  pulled  is broken apart.

Title: Method and apparatus for maintaining transaction ordering and supporting deferred replies in a bus bridge
Inventor: BELL MICHAEL D
IPC: G06F13/36
Filed: 1995-05-16
Abstract: A bus bridge (400) between two buses includes two request queues: outbound (420) and inbound (430). Requests originating on the first bus (401) which target a destination on the second bus (402) are placed into the outbound queue (420). If the request can be deferred, decoding circuitry (415) within the bridge (400) issues a deferred response to the originating agent, indicating the request will be serviced later. Bus control circuitry (425) removes requests from the outbound queue (420) and executes them on the second bus (402). When bus control circuitry (425) receives a response from the destination agent in response to this execution, it either returns the response to the originating agent immediately or after passing it through the inbound queue (430). Both queues (420, 430) have associated data buffers (520, 530) for transferring data between the two buses (401, 402). Requests are handled similarly in the opposite direction, with the request originating on the second bus (402) for execution on the first bus (401).

Abstract: An automatic flow shift valve for use with swimming pool cleaning systems including a pool skimmer system for removing floating debris from the surface of the pool and an underwater pool cleaner system for removing debris from the floor of the pool, both of such systems operating through water suction by the periodic "on" and "off" cyclic operation of a suction pump. The valve is mounted over a flow orifice in a cover plate which is removably secured across the top of the well and removable debris basket of the skimmer and the underwater pool cleaner is connected by a hose to a second opening in the cover plate. The valve includes a central, fixed-position shift cylinder enclosing upper and lower spaced, but interconnected, pistons which are reciprocative within the shift cylinder. The upper piston is spring biased upwardly to open the valve when the pump is "off". The lower piston bears an orifice closure plate for closing off water flow through the skimmer and the flow orifice of the cover plate based upon water suction force on the closure plate during one cycle when the pump is "on", thereby causing suction operation of the underwater pool.  A control cam located between the upper and lower pistons is operable to lock the pistons in an intermediate upper position within the shift cylinder to maintain the valve open during a second cycle when the pump is "on", thereby causing suction operation of the skimmer.
