Abstract: A golf cart enclosure system for the creation and maintenance of a pleasant climate within a golf cart during poor weather conditions and for allowing simultaneously care-free ingress and egress with respect to the golf cart without the golfer having to open a door on the golf cart, with the enclosure system including flexible partable strips of see-through plastic which extend across the vertical dimension between the golf cart canopy and the golf cart body, the top ends of the flexible strips being attached with a semi-permanent attachment device to the golf cart canopy in a rear-to-front overlapping fashion, so that during forward motion of the cart, the strips remain in position and in contact with one another; the bottom ends of the strips connected to the golf cart body by permanent magnets, or electromagnets wired to the golf cart battery and activated either automatically by the driver's footpedal, or by an on-board switch, with the enclosure system also including a front and back protective panel, th

Abstract: A drain valve modifiable for use under different water pressures by merely changing the material of valve member within the drain valve. The drain valves are used in a fluid system to produce a fluid system that respond to local water pressure conditions. In one embodiment the drain valves include an extended inlet port that project into the water supply line to prevent complete drainage of the irrigation system and thus conserve water from one watering cycle to the next. Another embodiment of the drain valve includes multiple resilient members for sequence action in opening and closing of the drain valve. Still another embodiment permits a user to change the size of the drain passage by placing an insert in the drain passage of the drain valve.

Abstract: An improved vacuum breaker valve that uses a sliding shuttle that is held in a first closed position by a compression spring and in a fluid transmitting position by the fluid pressure from the fluid supply with a fluid diverter that directs fluid into a chamber and through a fluid resistor so that the fluid pressure in the chamber can generate forces to slide the shuttle along a fluid diverter until the fluid can flow through the valve with the valve including a resilient spring to force the sliding shuttle to a open vent condition where the valve provides both a physical barrier to backflow as well as a vent to quickly and effectively vent any fluid in the downstream pipes into the atmosphere to protect the fluid supply.

Abstract: A T-branch formation device using two identical side members to form a snap-on saddle around a resilient plastic pipe and a screw-in coupling cutter which cuts through resilient piping, retains the cut piece, and simultaneously provides a threaded surface for attaching a branch tubing which forms a leak-proof connection.

Abstract: A two phase quick setting and quick releasing pipe pulling device having an outer housing for engaging the exterior of a plastic pipe and interior radially expandable and contractible jaws that can be quickly set on the interior surface of a plastic pipe by applying a blow to the housing with the expandable jaws responsive to a pulling force on a central shaft located in the housing to further radially expand the jaws to further engage the interior of a plastic pipe as one pulls on the pipe pulling device with the expandable jaws also operable to be quickly disengaged from the interior of the plastic pipe by applying an axial blow to the central shaft of the pipe pulling device.

Abstract: The present invention comprises an automatic self-draining backflow prevention valve having an internal cylindrical resilient sleeve that expands or contracts in response to water pressure to coact with a two way valve that provides for automatic self-draining of both the water faucet and the backflow prevention valve when the water faucet is shut off.

Abstract: A drainage valve for use in pressure systems where pressure surges occur for draining an underground water system when the water pressure in the underground water system is off and for sealing the drainage valve against drainage when the water pressure is on comprising a housing having a first annular support and sealing surface and a second annular support and sealing surface for supporting a member that is nonextrudable through a drain passage in the drainage valve under normal operating pressures and surge pressures encountered in water supply systems and to permit said nonextrudable member to open said drain passage when the water pressure is off.

Abstract: The present invention describes novel solvent cements which are a combination of a solvent which is a 5- or 6-membered ring lactam and a cosolvent which is one or more lower alkanols and/or one or more lower alkyl esters of lower alkanoic acids and, optionally, includes a water-insoluble polymer such as PVC or ABS.

Abstract: A floating dispersal member for controllably dispersing a material into a fluid wherein the dispersal member contains a compartment to hold a dispersant and a visual indicator to alert a person to when the dispersant is dissolved. In another embodiment the flotating dispersal member includes a flotation compartment that holds the dispersal member in an upright condition when there is a dispersant in said dispersal member and a weight which flips the dispersal member in an end-for-end condition when the dispersant is dissolved in said dispersal member.

Abstract: An inline dispersal valve is constructed with a chamber into which a material to be dispersed into a fluid stream may be inserted. A first fluid deflector is used to direct fluid away from the fluid stream into the chamber to permit the fluid to absorb the dispersant, and a second fluid deflector, oppositely facing, that directs the fluid back into the fluid stream after it has passed through the chamber. The bottom of the chamber has a pair of openings in a line with each other which have an axis that is substantially normal to the axis of the fluid flow in a main stream. A rotatable plate having a pair of apertures of a specially designed tear drop shape controls the amount of fluid that flows through the chamber in accordance with the amount of available area to the fluid stream due to the alignment of the apertures with respect to inlet and outlet ports, respectively. The plate which contains the apertures is preferably a circular disc which carries a curved row of rack teeth.

Abstract: An apparatus for controllably dispersing material into a fluid stream with the apparatus having a housing with a bottom section that attaches to a pipe line and a top section having a cylindrical sleeve with a porous container therein to support a solid fluid soluble material. The porous container can be controllably inserted into a fluid stream through coaction of a spring and cap to control the amount of soluble material entering the fluid stream. A sealing surface on the porous container and the cylindrical sleeve prevents fluid from escaping from the line when the porous container is in the up position and an upper seal prevents leakage past the cap when the valve is in operation.

Abstract: An attachment for flexible or rigid tubing including a male connector for extending into frictional engagement with either flexible or rigid tubing. The male connector includes a sealing member and a set of annular concentric ridges that provide means for sealing the male connector with either flexible or rigid tubing. A compression fastener holds the male connector and tubing in sealing engagement when the attachment is pressurized.
