A balanced fluid pressure regulator of the disclosed embodiment comprises a balancing bellows inside a sensing bellows to minimize the supply pressure effect for improved performance while reducing the size and weight of the regulator in comparison to a conventional regulator. A sensing duct communicates the enclosed space between the bellows with the fluid passage of the regulator downstream from a poppet valve. The cross-sectional area of the fluid passage is reduced in the vicinity of the sensing duct for decreasing the pressure in the enclosed space at high gas flow rates. The valve seat in the regulator is supported so it is free to move during assembly of the regulator to self-align the seat with the poppet valve.

Valve

A high Cv bulk process valve, control system and method convey a process gas or liquid for manufacturing semiconductors through a fluid passage. The fluid passage contains an aerodynamically shaped expansion chamber within which a valve seat and a moveable poppet are arranged for opening and closing the fluid passage. The aerodynamically shaped expansion chamber includes a conically expanding entry and a conically contracting exit and is shaped such that the resistance to flow of the process gas or liquid through the fluid passage of the valve is very nearly the same as through a straight tubing having a cross-sectional area of an inlet to the valve and a length of the fluid passage through the valve. The valve can be added or subtracted from a gas or liquid control system with virtually no changes in pressure drop of flow restriction, when the valve is in the open position. The valve minimizes the energy consumed by valves in semiconductor gas systems.

A golf club ball-striking face (6) utilizing a metal with ten times or higher damping capacity compare to the steels presently in use for club faces. The metal has the strength near that of the steels. The preferred metal is of the class of shape memory metals of alloys including: copper, nickel, aluminum, and manganese. The face is an insert plate whose front ball striking surface is narrower than its rear surface and is secured into a cavity formed in the club head, where the plate may be as thin as 0.010 inches or the plate may extend to nearly the entire thickness of the club head.

A shape memory effect actuated diaphragmatic anti-scald valve, including a valve housing having a fluid flow path therethrough and including a pilot chamber. There is a first valve seat within the housing and a second valve seat within the housing and downstream from said first valve seat. A pilot valve is located within the chamber of the valve housing for preventing fluid flow through the chamber in which the pilot valve element is located when the SME valve is in its normal flow position and a first valve element is retained seated on the first valve seat by the pilot valve. There are means for controlling the open and closed positions of the pilot valve depending upon the temperature of the fluid flowing through the SME valve. A diaphragm defines a second valve element for the second valve seat and located in the main path of flow for the SME valve and being in an open position when fluid is flowing through the normal flow path and the fluid is directed at the bottom thereof for holding it off the second valve seat the second valve element in its first position opens a port which allows water pressure on the top side of the center of the diaphragm urging it to close against the second valve seat and in its second position in which the second valve element is open and the diaphragm is moved to its open position unseated from the second valve seat to permit normal water flow.

Temperature responsive, pilot operated line valve with shape memory

The invention provides a self-contained automatic temperature-responsive three-way line valve. A tubular valve member is axially slidable between first and second limit positions for selectively directing fluid from an inlet port to a first outlet port or a second outlet port. The valve member is disposed between a pair of opposed compression springs, one being a conventional spring biasing the valve member to the first limit position and the other being an SME spring which overcomes the bias of the first-mentioned spring when the fluid exceeds a given temperature.
