Abstract: Valve apparatus for controlling flow of particulate material, such as sand or other abrasive material, from a tank or hopper. The valve has a unitary plunger which is movable axially with respect to a lateral particulate material inlet between positions closing and opening the inlet, the plunger being moved by rotation of a threaded portion of the plunger through an internally threaded cap or bonnet opening. The valve body passage through which the plunger is disposed, and the plunger itself, are formed to have abrasion-resistant surfaces. A lateral air pipe nipple sealed to the valve body receives the abrasive material flowing through the valve for use in sand blasting operations.

Abstract: A valve for a tubeless tire which is adapted to be secured in a bore of a tire rim comprises a tubular valve body with an outer rim surface engagement flange formed on its periphery and spaced from an inner rim surface engagement flange by the length of the bore through the tire rim. At least one of the outer or inner rim surface engagement flanges is deformed into engagement with the associated tire rim surface. Preferably, a sleeve of a soft material is located around the body between these flanges and it is deformed and compressed into a groove formed by the respective flanges over each end surface of the tire rim. The construction is such that when the valve body is inserted from the exterior of the rim to the interior, the inner flange is formed by bending over the end of an internally formed sleeve which encompasses the end of a soft body or gasket and bends it into engagement with the associated inner surface of the tire rim.

Abstract: A valve for adding ingredients to or sampling the fluid flowing through the valve includes an adjustable solid stem which can be extended through the flow path of a pipeline to form a seal with a seat positioned directly opposite the stem.

When the stem is seated, flow still occurs in the flow path.

Abstract: A gated irrigation pipe is operated by a pneumatic control system which automatically opens and closes the gates. Each gate is slidable along the pipe surface and is coupled to a pair of parallel air conduits extending longitudinally along the pipe. The conduits are connected midway between their ends to a common movable pneumatic cylinder which receives therein a piston fixed to the exterior of the pipe. The conduits communicate with opposite ends of the cylinder, and serve as both an air line to the cylinder and an operating linkage which opens and closes the gates and which will not cause damage to the gates in response to differentials of expansion and contraction. A plurality of pipes thus equipped are serially connected to form an irrigation pipeline and the air conduits are interconnected at the pipe joints by flexible hose couplings which may be preset any time during each watering interval.

Abstract: Disclosed are longitudinally slidable gates for the longitudinally extending outlet ports of arcuately walled irrigation pipes, the gates being of the general type wherein a gasketed inner-plate cooperates with and is longitudinally co-movable with an outer cover member slidably disposed at the pipe outside surface. The gate concept disclosed herein includes a boss attached to and extending radially outwardly from the inner-plate and longitudinally guided by the pipe water outlet port, the gate cover member being afforded vertically movable relationship to the inner-plate and resiliently urged theretoward and to the intervening pipe wall with disjointed separable spring means to accommodate the pipe wall given finite-thickness. Preferably, the boss includes a transverse bridge defining a boss longitudinal bore to accommodate therealong an inexpensive, reliable and rugged leaf spring, which might be desireably independently formed of reinforced resinous material.

Abstract: The invention relates to a valve assembly adapted in conjunction with a valve actuator to provide positive control of the stroke of hydraulic cylinders. The valve is attached to a pressure port on the cylinder and the actuator assembly is positioned on the side of the cylinder and held by means of clamps. The stroke of the cylinder is limited when the actuator arm is clamped on the piston shaft at a distance shorter than the full stroke of the cylinder. In this condition as the shaft moves into the cylinder, the actuator arm contacts closure means within the valve thereby closing off the valve and preventing further retraction of the cylinder. The apparatus of the invention is adapted to be supplied in the kit form and can be readily attached, externally to any existing hydraulic actuator.
