Abstract: A flexible and resilient normally planar flap valve having two portions which together form a generally elongated oval shape. One portion of the flap has a greater radius than the other portion to restrict movement of the flap when installed in a tubular member. When installed the valve forms a generally arcuate shaped flap having a outer surface configured to conform to the cross-sectional shape of the tubular member. The flap has two operative positions; a first position in which the valve allows air to flow unrestricted through the tube; and a second position in which the valve seals off the main air source and directs air between a side opening and the tubular member. The flap is provided with a handle molded directly to one end of the flap, thereby creating a single piece integrated lever and live spring valve.

Abstract: A packing resistant valve has a gate rotatably mounted within an angled valve body and an inlet face of the gate defines a concave recess for inducing eddy currents in fluid flow impinging thereon. The eddy currents direct fluid flow away from the valve body, reducing the tendency of the fluid to accumulate within the valve body. Because the valve body is angled, material tends to drain from the body under the influence of gravity. Also, the angled configuration results in the formation of an air pocket within the valve body, precluding packing therein. In one embodiment, a mechanical seal is provided to preclude fluid leakage across the valve stem. In a further embodiment of the invention, a diverter valve assembly is disclosed, which includes a diverter plate for preventing the impingement of fluid against the closed valve disk.

Abstract: A directional dump valve is disclosed which allows for the rapid dumping of water from a standard tank truck or similar vehicle. The device has three main dumping ports, which are quickly selected by adjusting the position of the water control doors. This adjustment can be made quickly with the handles provided on the device. A quick action locking device is disclosed which will lock the handles into position once the proper port has been selected. Two of the outlets are fitted with conduits to channel water from the rear of the vehicle laterally past the ends of the truck. Baffles are provided on the control doors to reduce turbulence in the valve, and to help quicken the flow through the side discharge conduits. The conduits can also be extended by the use of extensions, which can be folded up on top of the conduits when they are not needed. The valve is designed to be flange mounted to the tank truck and can be disassembled for quick repair.

Abstract: A diffuser is provided with three discharges. Two of the discharges are directed in one direction and, when installed, would be directed towards the outside wall of the conditioned space.

Abstract: An electromagnetic valve for handling fluid media has a valve mechanism which includes at least one valve seat and a valve-closing member which cooperates with the valve seat or seats. The motion of the valve-closing member is controlled by linkage that is connected to the moving arm of an electromagnet, while a return spring urges the armature in the direction opposite to the magnetic force. In order to permit the seating of the armature against a stop at the limit of its energized travel, while exerting a calibrated force on the valve seat, the armature is permitted to travel beyond the point at which the valve-closing member is arrested. The additional motion of the armature takes place against the force of an auxiliary spring which compresses during that part of the motion. When the coil is de-energized, the auxiliary spring urges the armature back into direct contact with the linkage, whereafter the motion transfer is loss-free.

Abstract: This invention relates to an apparatus for maintaining the desired temperature of a fluid, or more specifically, to reducing the temperature of the fluid to a desired level. The apparatus generally relates to one including a heat exchange coil through which the fluid to be cooled passes and over which an air stream is moved to absorb heat from the coil. In such an arrangement, it is common to increase the heat transfer efficiency of the coil by maintaining the same in a wet condition by means of a water spray or cascade, for example. In this manner, evaporation of the water causes an accelerated transfer of heat from the fluid in the coil for a given amount of air flow thereover than would be the case if the coil surface was not drenched. The present invention is directed to the disposition of a propeller air moving means sufficiently downstream of the cooling coil so as to be substantially free of air flow obstructions.

Abstract: A valve for controlling the fluid flow between two generally coannular ducts. The valve is provided with a pair of back-to-back, mutually facing flow mixers of the daisy variety, each associated with a section of the coannular ducts. Each mixer transists the two coannular duct passages into a plurality of circumferentially separated chute passages communicating alternatively with the inner and outer ducts, the mixers being indexed with respect to each other by half a chute width. A stage of radially extending, pivotable vanes cooperates with the chutes of both mixers and allows both the inner and outer upstream duct flows to be directed to either the inner or outer downstream duct, depending upon the orientation of the vanes. Alternatively, either or both of the fluid streams can be blocked off entirely. Complete flexibility for flow inversion is obtained without turning or indexing the flow through the vanes by more than half a chute width, thereby maintaining high efficiency.
