Title: Two-stage externally adjustable control valve
Inventor: SHINLER KEVIN LEROY
IPC: F15B13/04
Filed: 1995-05-29
Abstract: Material such as trash or refuse is packed in a container by opposed hydraulic packing and ejecting cylinders. Each cylinder is controlled by a hydraulic control valve with the control valve controlling the ejecting cylin-der being, in effect, operated by the control valve for the packing cylinder. This is accomplished by sensing the pressure applied to the packing cylin-der and when the pressure reaches a predetermined level, a pilot dump valve, in the ejecting cylinder is opened to allow the piston in the ejecting cylinder to retreat. When the pilot pressure drops below the predetermined level, the pilot dump valve closes, allowing the packing cylinder to exert additional packing force. In this way the piston in the ejecting cylinder inches back and the material is intermittently packed. An anti-cavitation check is provided so as to fill the chamber of the ejecting cylinder as the piston retracts.

Title: Computer system speed control using memory refresh counter
Inventor: THOME GARY W
IPC: G06F13/16
Filed: 1995-10-11
Abstract: A computer system which provides for slowing the effective speed of a microprocessor.  The microprocessor includes a disabling input that when deactivated disables operations of the microprocessor on the processor bus.  A computer system according to the invention periodically deasserts this signal with the certain duty cycle, allowing the microprocessor to continue to perform necessary functions at an effective rate compatible with older microprocessors, but never requiring an actual clock frequency change.  This periodic deassertion is performed in response to a memory refresh counter that periodically counts down to zero and is reloaded.  By comparing an input/output register with the refresh counter, and by adjusting the input/output register, the deasserting signal to the processor is periodically deasserted with a selectable duty cycle.

Inventor: OZUTSUMI MICHIO
IPC: H01L35/20
Filed: 1996-03-08
Abstract: A thermo-electric power generating element has the structure that two kinds of metal sheets or foils 10, 11 being in the relation of thermocouple combination are laminated together and connected at one end and the other end alternatively, so as to form a plurality of thermocouples connected in sereis. When hot junctions 12 are held at a high temperature, a temperature gap along the thermal flux is generated in the sheets or foils 10, 11.
