Abstract: A clamp valve is made which comprises a hollow member open at one end and which has a pair of apertures through side walls thereof. A slide is movable in the hollow member and has a transverse aperture therethrough so that a conduit which has a pliable resilient wall can in use be passed through both of the apertures in the hollow member and the aperture in the slide. Biassing means are provided to bias the slide relative to the hollow member so that the conduit is in use normally clamped between an edge of the aperture in the slide and an edge of one of the apertures in the hollow member so that the conduit is normally closed to fluid flow.

Abstract: A locking valve construction including a housing, a valve member in the housing, a fluid inlet and a fluid outlet in the housing, a valve member rotating key for rotating the valve member to an open position for selectively effecting communication between the fluid inlet and the fluid outlet, a holding member effectively mounted on the housing for holding the housing against rotation relative to a base when the valve member is being rotated by the valve member rotating key, and mounting structure for mounting the housing on the base for permitting the housing and the valve member to rotate as a unit in the event that the holding member is rendered inoperative to thereby prevent movement of the valve member relative to the housing to an open position.

Abstract: A high performance pinch tube valve for accurate, reliable, high speed and precise control of relatively low viscosity fluids. The valve is particularly adapted for use in apparatus for controlled pattern dyeing of textile material, such as carpet, with liquid dye streams. The valve includes a valve block having a bore receiving a flexible tube, and a passageway communicating with and disposed generally transversely to the bore, the intersection of the bore and the passageway defining a pinch chamber. A tube pinch off member is selectively reciprocal within the passageway into the bore for forcing the flexible tube closed. The tube pinch off member comprises a piston rod and a freely-floating ball disposed between the end of the rod and the flexible tube. The pinch chamber has a flattened wall portion formed in the bore opposite the communicating passageway. Additionally, the communicating passageway has a larger diameter than the bore.

Abstract: A pressure relieving device for use with gas flowmeters, pressure regulators and other fluid flow equipment is described. The device includes an O-ring and means for compressing and retaining the O-ring to provide a fluid-tight seal under normal operating pressure, but having a gap positioned such that the occurrence of an excessive pressure causes a portion of the O-ring to move into and through the gap to relieve the excessive pressure. A passage for enabling the fluid to contact the O-ring is sized to allow sufficient flow to relieve a fluid pressure substantially in excess of the normal operating pressure.

A rotatable cylindrical element that includes said toothed segment extends through said sealed casing to accept a lever for actuating the segment to thereby move the rack and its associated plug.

Abstract: An all metal gas metering valve is used in high vacuum installations in the range of 10.sup.-9 Torr. 1/sec. to 100 Torr. 1/sec. relative to helium and 20.degree. C. ambient temperature. An axially extending tubular member forming a part of the valve housing contains a rotationally symmetrical valve body. A bushing laterally encloses at least an axially extending part of and is welded to the tubular member around two welded seams spaced apart in the axial direction of the tubular member. A pressurized medium can be charged into the joint between the inside surface of the bushing and the outside surface of the tubular member and limited by the welded seams. The pressure acting on the tubular member constricts its cross-section and reduces the space between the side surface of the tubular member and the valve body. Initially, the space between the valve body and the tubular member can be kept very small so that a wide adjustment range is available by varying the pressure acting on the tubular member.
