Abstract: An improved valve for high speed, high pressure pumps, having a dished, rectangular-sectioned, radially stretched seal overhanging the valve body to both cushion and seal the body's closure against the valve seat, and which is pre-stressed in tension sufficiently to stiffen against pinch off under the high fluid pressures of, and to attain full elastic shape recovery in the very brief time interval between the valve closings of, such pumps.

Abstract: Rack or platform apparatus for receiving loaded pallets from the rear, forwarding them on one conveyor or trackway for order picking from the front, and then returning empty pallets on another conveyor or trackway for pickup from the rear.

Abstract: A triangular-shape lawn rake achieving a straight edge with teeth of uniform length; having a unitary, flat sheet teeth-handle joining socket head; and having resilience and stiffness in proper combination and without sacrifice of low cost or light weight.

Abstract: An actuator for reciprocating stem control valves having a linkage system affording variable force, reversible action, and adaptability to different valve strokes.

Abstract: A fluid resistance device being part of a fluid system and having high resistance, fluid energy absorbing passages within the plane surfaces of equally shaped circular plates which overlap each other in a prearranged pattern, each plate consisting of equally spaced circular segments, one half of which have a number of small openings while the other half define a large opening allowing for communication in planar and perpendicular direction between said small passages in both the adjacent segments.

Abstract: Apparatus and method for the calibrating in the field of media and process condition change transmitters and controllers. Means and method for high resolution calibrating of condition change measuring and indicating apparatus by spring means external to the measuring by, and having a spring rate multiplyingthe change response of, such apparatus. Means and method of calibrating media and process change transmitters and controllers by inferentially simulating full span condition changes.

Abstract: Sinuous passage method and means of attenuating the noise generated by the expansion of a fluid through a valve. A winding-passage-incorporating tubular element provided between the valve and the downstream pipe. For attenuating the noise generated by a pressure reducing valve, or other fluid expanding restriction, a device having its inlet end substantially engaging the downstream face of the valve, and comprising a tubular element enclosing a plurality of lengthwise partitions, and between said partitions a plurality of transverse, flow deflecting means defining with said partitions a plurality of individual, continuous, zigzag passages.

Abstract: A fluid resistance device being part of a fluid system and having high resistance, fluid energy absorbing passages along the interface between a ringtype member and a cylindrical male insert, and wherein said passages consist of a number of teeth-like baffles which are off-set from each other and which are separated from each other by circular grooves providing nearly rectangular throttling restrictions in series for the fluid passing generally along the longitudinal axis of the male insert.

Abstract: A variable resistance type control valve throttling trim having high resistance, fluid energy absorbing passages formed and controlled between the intersection of a cylindrical valve plug slidable co-operating with a cylindrical valve seatring and wherein the number, length, area ratio and specific fluid resistance are a function of the engaged length of the cylindrical plug portion in respect to the seatring bore and wherein the fluid energy absorbing passages consist of a pattern of slots and grooves radially inwardly penetrating the cylindrical wall of said valve plug and/or radially outwardly penetrating the cylindrical inside wall of said seatring bore.
