Abstract: A beverage dispenser has a container for beverage fluid that has a flat bottom that is above a space large enough to place a glass or cup. The container has a sidewall and a top edge of an open container that has a removable lid. A pair of actuator guards are on either side of a space near but below the top edge of the container where an actuator is located that projects through a notch in the top edge, plunging downwardly inside the inner wall of the container sidewall and jutting straight out to form a fork.

Abstract: An improved toilet flapper valve (10) designed to directly replace either a conventional toilet flapper valve or tank ball valve. The valve (10) allows a toilet user to selectively determine the quantity of water used for a toilet flush by controlling the time that a toilet flush handle (38) is held in the depressed position. The water quantity used depends on whether liquid or solid waste is to be flushed. For liquid waste, a partial flush is used; for solid waste a full flush is recommended. The valve (10) consists of a resilient body having a cavity (12) located over the toilet tank drain (34). The cavity houses a weight (16) that fulfills two functions: it provides the weight necessary to make the valve non-buoyant and it produces under the area of the weight, a flat rigid section (18) that extends radially over and beyond the perimeter of the valve seat (36). This rigid section provides a positive seal without sagging which can produce unnoticed leaks.

Abstract: An access port cover is fitted with a sealing plug that is adapted to fit inside a conduit to provide an occluding seal. The conduit is also fitted with an inner flap that is automatically closed and latched when the cover is closed and latched.

Abstract: A high performance damper blade and damper blade seal combination including a damper blade having a planar portion perpendicular to the damper blade and a damper blade seal including a base and two upwardly extending legs. One leg of the damper blade seal contacts the damper blade body, while the other leg of the damper blade seal contacts the outside edge of the perpendicular tip portion of the damper blade. The tip of the perpendicular damper blade portion contacts the base of the damper blade seal for providing a third point of contact between the damper blade and the damper seal to ensure minimum airflow through the damper blade and end seal when the damper blade is in the closed position. Furthermore, the leg of the damper seal which contacts the outer side of the blade tip portion operates advantageously as a wind break to prevent leakage through the damper blade and seal combination due to wind gusts when the damper blade and seal are employed on air handler units or air conditioning systems.

Abstract: A valve is installed into an underground conduit to control drainage of water through that conduit. The drainage control valve includes a perforated plate across the conduit.

A flap also made of flexible material is applied against the upstream surface of the plate and is formed with a peripheral edge taper whereby pressure applied on the flap by water upstream of the drainage valve forces the edge taper against the upstream plate surface to form a sealed joint between these flap and plate. The upper portion of the flap is attached to the upper portion of the plate through screw and nut assemblies. These assemblies traverse rigid washers inserted in respective holes made in the flap.

Abstract: The invention provides a tool for closing off the jet nozzles of jet pumps located in an almost inaccessible location inside the shell of a boiling water reactor. The tool suspended on a cord is lowered down through a narrow gap extending down along the major part of the shell of the reactor, a distance of approximately 30 feet. The tool is lowered onto a stationary projection--namely, a lug or ear--which provides a gauge point for height and lateral position and an anchorage for torque in a horizontal plane. With these two controls for the tool of the invention, a closure for the jet nozzle may be applied to each of the jet nozzles to close them off against outflow of the water contained in the shell of the reactor thereby avoiding the bleak alternative of taking the reactor completely out of service, which includes removing the fuel bundles and draining the shell.
