Abstract: A spray valve assembly adapted to be removably, threadably secured to spray boom manifolds or the like for subsequent spraying of insecticides or other agri-chemicals. Preferably the spray valve assembly includes a rigid valve body adapted to be threadably secured to a suitable spray boom or manifold; and a cooperating valve head which is threadably secured to the valve body. A generally tubular fluid admittance passageway coaxially, sealably defined within the valve body extends partially into the valve assembly, and terminates in the assembly spray output. A plunger associated with the valve head includes a ram portion which contacts an internal gasket to selectively block the admittance input to prevent escape of agrichemicals. The plunger means also includes an elongated stem coaxially received through the valve head which is fitted with a transverse pin which normally tracks within a suitable follower slot defined in the head.

Abstract: A valve assembly adapted to be coupled to the spigot of a conventional sink faucet, which valve can selectively divert water from the spigot to either an auxiliary filter or to a drain. The valve incorporates a housing having a threaded inlet, an internal chamber and first and second outlets. A slidably mounted spool defines a valve head, and normally directs the flow toward the drain, but the spool can be shifted to divert the flow to the filter on either a continuous or a "single-shot" basis.

Abstract: The operation of a gas burner, such as a Bunsen burner, is controlled by a remote control device including a diaphragm drive which responds to a fluid under pressure for operating the actuator of the burner whereby the gas supply is switched on or off. The diaphragm seals off a pressure chamber from a fuel gas supply chamber and is deformable by the pressure in the pressure chamber. Such deformation is transmitted to the burner actuator.

Abstract: A dispensing valve assembly comprising a slideable valve sleeve with a radially-directed dispensing outlet movable from closed position axially within a guide portion to open position axially-outwardly of the guide portion. Keying means between the guide portion and valve sleeve ensures that the dispensing outlet is normally directed downwardly but this keying means is flexible and can be overcome to permit twisting of the valve sleeve in the guide portion to break a seal connected therebetween. Finger-engaging means are also provided to facilitate closing.

Abstract: An apparatus and method for use with a bushing assembly of the type wherein glass fibers are drawn through an orifice plate having a flat undersurface against which bulk gas is directed to effect cooling and fiber attentuation. A selectively adjustable bulk gas nozzle has a plurality of discharge conduits with valves therein which are adjustable and capable of being selectively operated to close the conduits or return the conduits to a preset open condition. The nozzle and/or a binder applicator are supported for select movement toward and away from the path of the fiber being drawn from the orifice plate. A detector senses the presence of fiber being drawn from the orifice plate and, in the event of fiber break-out, initiates a series of steps to warn the operator of the bushing assembly and, in the event the break-out condition is not corrected, shut down the drawing operation.

Abstract: An electrical capacitor casing has a fluid filling hole sealed with a self sealing device. The sealing device includes a seat for the seal on the inside of the casing and adjacent of the opening, a resilient gasket, a biasing spring and a retaining housing to form an enclosure for the gasket and spring. A key is used to open the sealing device for drying and filling the case.

Abstract: A valve for controlling fluid flow is disclosed in which a fluid outlet is controlled by two separate components, one being tubular in shape and located inside the other hollow component. Both the hollow and the tubular components may either be the valve body and closing element respectively, or vice-versa. The two components are reciprocally slidable through elastic sealing rings along their common longitudinal axis, and are also rotatable about that same axis, whence the path of fluid flow may be readily controlled in a gradual manner from the fully shut position to the fully open position, depending upon the longitudinal position of a plunger element with respect to the valve body. The plunger is in a state of static balance with respect to any existing pressure or friction, as well as with respect to its own weight.

Abstract: The present invention provides a plug comprising a body having a sealing means arranged to sealingly engage with a portion of a vessel surrounding a drain outlet and a regulating means mounted on the body and arranged upon partial rotation to open or close the plug to permit or prevent respectively, egress of liquid from the vessel.

Abstract: A canister type vacuum cleaner having cylindrical walls and a bottom therein supporting at the upper open end thereof a suction type blower and filter is provided with discharge means attachable to the bottom of the canister and including a transverse slide adapted to close an opening formed in a supporting plate for the slide and an additional coaxial opening which is to be formed in the bottom of the canister, the canister also including a conical, funnel-like deflector having a central opening coaxial with the opening in the bottom of the canister, the slide forming a closure which is spring-pressed in closing direction and including a manipulating handle and an end which may be operated when the slide is in open position to maintain the same in said position to facilitate emptying the canister from the bottom thereof without requiring removal of the suction head and dumping of the canister.

Abstract: A frost-free hydrant includes a reservoir below the frost line which is completely sealed from ground water and which is emptied by a venturi in the valve when the hydrant is used. An indicator raised by a float warns of undue accumulation of water in the reservoir and seals the air vent to the reservoir. An actuating handle for the valve is depressed to permit water to flow and may be swung laterally in either direction to hold any adjustment from trickle to full flow. Anti-siphoning openings are included in the valve actuating rod.

Abstract: Gate valve apparatus is disclosed for use with holding tanks, such as on recreational vehicles, which utilizes electromechanical means to open and to close the valve.

Abstract: A pipeline comprises plastic pipe lengths interconnected by plastic couplings with telescoped joints and with plastic valves in each coupling. The pipeline is enclosed and supported by an adjustably suspended sheet metal housing assembly with a charged wire thereon to keep off fowls.
