Abstract: The present invention is directed to a sanitary mixing valve in which the valve housing is made of a ceramic material of unitary design and is interchangeable by being removably mounted to a connecting member having a cartridge valve assembly mounted thereto.
Abstract: The disclosure and drawings describe and illustrate a water mixer fitting having a temperature measuring means operatively coupled between the mixed water outlet opening and a display terminal disposed in or adjacent to the handle assembly.
Abstract: The present invention is directed to a straight-way and shut-off valve in which identical discs are arranged in face-to-face contact to provide a fluid-tight seal therebetween and means are provided whereby fluid is not trapped between the central rotatable disc and an outer disc so that upon expansion of the fluid, the discs do not shift outwardly due to axial pressure that would break the fluid-tight seal.
Abstract: A composite structure, e.g., a plastic-backed enamel steel product having high impact and thermal shock resistance is disclosed. The composite structure is formed having bonded thereto, a finished layer on one side thereof, and on the other side a layer of reinforced plastic to form a laminated structure. The plastic layer has a thickness of at least 1/8 in., and a density of between about 20 lbs. per cu.ft. and about 125 lbs per cu.ft. The finished layer is resistant to delamination when subjected to relatively high impact applied directly to the finished and/or plastic layer surface and to delamination when the composite structure is subjected to a sudden temperature change of about 180.degree. F.

Abstract: A single-lever sanitary water valve is provided with a fixed cylinder which has at least one water inlet aperture and serves to receive a rotatable and/or slidable piston, by means of which the inlet aperture can be wholly or partly closed and can be linked to the outlet aperture, the slidable and/or rotatable piston being controlled by means of a lever assembly. The lever assembly includes a rotatable cap mounted on the valve body to which is coupled the piston and the adjusting lever via at least two linkage members so that first, second and third pivot bearings are formed at their respective points of connections whereby lateral forces acting on the piston are substantially eliminated when the adjusting lever is shifted between its raised and lowered positions.
Abstract: This invention is directed to a nozzle or spout for a sanitary fitting, which is arranged and constructed to reduce the noise of fluid, (water), as it flows through the nozzle or spout passageway and which also removes particles entrained in the fluid, (water), before flowing through the nozzle or spout passageways, to prevent clogging.
Abstract: To protect the pump of a whirlpool bath against running dry and against blockage at the inlet, a pressure (or flow) sensor 14 senses pump pressure and generates a signal to keep a switch S2 in the pump motor electrical supply circuit closed. If the pressure signal ceases owing to blockage or running dry, the switch S2 opens. A manual override button 15 is held ON to close switches S1a and S1b in the power circuit for start-up. The sensor 14 and manual button 15 are preferably air pressure devices. Switch S1a is preferably an air-signal-operated latching switch whereby with the pump operating, the button 15 can be operated to switch the pump off. Relays RLA 1 and 2 may be used in conjunction with the electrical switches. A bleed hole may be provided between the button 15 and switch S1b to limit the period of time for which the motor could be run, with the bath empty, by prolonged inadvertent actuation of the button 15.
Abstract: A small, reliable diverter valve that maintains a relatively constant flow through a spray nozzle in spite of water supply pressure fluctuations and that positively terminates flow from the faucet spout during hand spray operation. A variable elasticity cup seal keeps constant area passageway to the spray nozzle in spite of water supply fluctuations. A normally open path, moreover, enables air to flow from the spout into the water supply system in conditions of negative supply pressure and thereby assists the cup seal in preventing backflow from the spray nozzle into the fresh water supply.

Abstract: A straight-way valve comprising a valve body having regulating elements is mounted therein. The valve regulating elements include a plurality of discs, one of which is mounted for rotation and at least one of the other discs is statically mounted in valve body. The rotatable disc has a plurality of flow ports, which correspond with flow ports formed in the at least one static disc. The at least one static disc is arranged in face-to-face contact against the rotatable disc to form a fluid tight, mechanical seal. An actuating device is coupled to the rotatable disc and is mounted for rotation in said valve body. The actuating device includes means, which extend through the valve body for rotating the disc from an opened to a closed position.
Abstract: The invention relates to hinge preparation assembly for mounting in each of the mortises formed in the hinge jamb of a steel frame. The hinge preparation assembly includes a hinge reinforcement member having a plurality of spaced apart threaded openings for mounting a leaf of a standard weight hinge set thereto. A hinge conversion means is removably mounted to the hinge reinforcement member so that upon its removal, the hinge preparation assembly is converted from a standard weight hinge preparation to a heavy weight hinge preparation and capable of mounting a leaf of a heavy weight hinge set thereto without requiring changing the hinge jamb of a steel door frame or modifying the hinge mortises thereof.
