A rotary valve actuator that effects rotary movement of a rotary valve includes a heavy plate member coupled with a linear motive source, which reciprocates the plate member between a first position and a second position. A first pair of flexible pull connectors, such as lengths of roller chain, are attached to the end of the plate member, and wrap around a wheel. At least one second flexible pull connector is disposed between said first flexible pull connectors and is attached to the other end of the plate member, and wraps around the wheel in the opposite direction of winding as for the first flexible connector.

Automated apparatus and method to determine physical properties of materials as they are moved relative to each other while in contact are disclosed. Physical properties between materials of interest (e. g. , galling resistance, coefficient of friction, and wear rate) are derived under a variety of conditions including dry unlubricated condition, at ambient and at extreme high and low temperatures, lubricated, or when submerged.

A method and apparatus to boost the fluid pressure of a solids-transporting liquid in a pipeline, without applying any forces directly to the solid particles. A method and apparatus are shown to remove the solids from the liquid, boost the pressure of the strained liquid, and then to re-inject the solids into the liquid at its higher pressure, all without damaging even fragile solids.

A throttling element, and throttling device utilizing the throttle element, provide absolute minimum possible resistance when in the fully opened position yet easily and effectively throttles the flow, so as to introduce a variable pressure drop, upon rotation utilizing conventional actuators. The device cannot be closed off completely, and it is possible to produce it in the same cost range as for butterfly valves yet having significant advantages thereover. The throttling element includes an annular metal substantially spherical segment having an exterior arcuate extent of about 80. degree. or less (e. g. about 60-70. degree. ) with first and second elongated metal shaft stubs extending radially outwardly from the exterior of the annular substantially spherical segment, on opposite of the segment the dimension of elongation of the shaft stubs. The element may be mounted in a housing having an interior bore with a first diameter, the throttling element itself having an interior bore with a second diameter substantially the same as the first diameter so that minimum resistance to flow is provided in a fully open position. The width of the exterior extension of the throttling element is between about 50%-70% of the first diameter with the first width and second diameter mentioned so that the throttling element cannot preclude or substantially preclude fluid flow through the housing interior bore regardless of what position the throttling element is rotated to.

A ball valve assembly that is uniquely suited for use in extremely high and low temperature applications where solid particles are frequently present within a flowing fluid. The valve includes a one-piece ball and stem or shaft element and the bore of that ball together with separate, removable end members, inserted from opposite directions into a passage extending through the valve body, form the valve's fluid-flow path. The valve body includes a second bore which can either extend through the entire valve body, perpendicularly with the other passageway, or can instead extend perpendicularly from that passageway to the exterior of the valve body in only one direction. The ball stem is rotatably retained and sealed in this second bore and the bore is dimensioned so as to be at least as large as the diameter of the ball so that the ball can be removed therethrough. In one embodiment the inner ends of the separate end members forming part of the fluid flow path are shaped to correspond to the exterior shape of the ball and contain a solid seat and a solid elastically compressible behind-the-seat seal. In another embodiment in-line removal of the ball and stem element is possible due to the use of separate cylindrical sealing elements positioned between the ball which also form part of the flow passage and seal the area between the ball and end members.

A butterfly valve that has a metal valve seat and a metal vane, providing fluid-tight metal-to-metal sealing. The valve seat is annular and has an inner circular line surface for engagement with the metal vane. The vane is a conical angle-transported disc, the upper face of the disc being angle-transported between 20. degree. and 40. degree. with respect to the lower face. Both faces are true circles, as is every section of the vane parallel to the faces. When the vane mates with the valve seat, true circular line contact sealing results, the valve seat only being very slightly deflected by the vane to effect sealing.

A diverter valve assembly that diverts flowable material from an inlet to one of a plurality of outlets. An outer tubular housing has an inner element mounted therein for rotation with respect to the housing about a generally vertical axis of rotation. The inner element is in the shape of a truncated cone. An inlet is provided at the top of the housing and a plurality of outlets are spaced around the sides thereof. A diverter element is rigidly mounted to the inner element and extends through the open top of the inner element and through a side thereof -- 90. degree. from the open top -- to cooperate with one of the plurality of outlets. Outlet arm members extend through the housing and make sealing contact with the outer surface of the inner element. Rotation of the inner element to position in cooperation with a particular outlet allows the flow of flowable material through the housing inlet, through the diverter element, and through the particular outlet arm.

A ball valve assembly and method of construction. The valve includes a one-piece ball and shaft in a valve housing formed of a body portion and an end portion, the body portion being cast. The body portion has a flow port at a first end thereof and a large opening at a second end thereof, and an elongated passageway is formed in the body portion for receipt of the shaft. A relatively thick wall portion is disposed toward the body first end and a relatively thin wall portion toward the body second end around the passageway. The passageway can be smooth bore or threaded throughout its length. A scallop may be formed in the relatively thin wall portion extending substantially perpendicular to the direction of elongation of the passageway, the scallop being machined or being formed during casting. The shaft is inserted through the body portion large opening and through the scallop to and through the passageway, and then the ball is moved so that it is in sealing relationship with sealing means associated with the body portion. The end portion is connected to the body portion, and a bushing is affixed in operative association with the passageway threads or bore for supporting and sealing the shaft.
