Abstract: A mixing valve for a faucet includes a cartridge and a chamber of a body and a reversing piston within a bore positioned below the chamber. The piston has passageways therethrough in communication with the inlets of the body and also in communication with respective entrances of the cartridge. As the piston is rotated 180.degree. from its initial position, the passageways connect the opposite inlets with the respective entrances in the cartridge. As such operation of the handle can always be conventional where movement of the handle to the right provides cold water and to the left provides hot water irrespective as to which inlets in the body provide the hot and cold water.

Abstract: A mixing valve 10 has a cartridge assembly 20 therein which has stationary plate 22 having hot and cold openings 24 and 26 and a movable plate 28 slidably mounted thereupon. The movable plate has a surface 29 abutting plate 22 free from apertures. Valve plate 28 moves translationally between an open and closed position and rotated between a cold and hot position. The valve plate can be rotated through approximately 180 degrees with a tooth 66 of plate 28 leveling the mixing profile at the comfort zone between the hot and cold positions (FIG. 1). The valve plate 28 is controlled by a drive lever that can be either rotated about a vertical axis or moved in a vertical plane.

Abstract: The invention as shown herein demonstrates a prefabricated chimney which can be manufactured in sections of convenient length for handling and shipped to construction sites for venting boilers or the like. The chimney sections are of the multi-wall design whereby the inner tube conducts hot exhaust gases from a fuel-burning chamber to the outside. Tubes which are concentric or coaxial with the inner tubes insulate the building or other structural members from contacting the hot inner tube and insulating layer of air or otherwise retards the heat flow from the inner tube. The inner tubes of the sections are joined by a containment band which tightly engages the end flange of the inner tubes which may have rectangularly-shaped cross-sections.

Abstract: An adapter for converting a condenser into a thermal siphon radiator includes a housing that has an outlet port connected to the fill inlet of the condenser, a side inlet port connected to a conduit and a fill inlet that is sealingly engaged to a radiator cap. The radiator cap has a valve element that seats against a sealing surface in the adapter. The surface is interposed between the inlet and the two ports. In addition, an overflow and return port is positioned above the sealing surface and is connected to a reservoir.

Abstract: A method of manufacturing faucets and spouts, faucet inserts and faucets and spouts manufactured by the method. The faucet or spout includes an upper housing plate and a lower housing plate, a peripheral flange being provided on each of the housing plates such that the flanges mate with a seal disposed between them in fluid sealing relationship, the housing plates having spaced apart surfaces extending from their respective flanges to define a chamber. The faucet inserts include a valving member rotatably received within a housing member, the housing member having an internal conical surface adapted for mating engagement with an external conical surface of the valving member, the valving member having a port adapted to be reversibly aligned and misaligned with a port in the housing member for selectively allowing and shutting off fluid flow.

Abstract: A compression type coupling 10 for pipes has a body member 12 and a fastener member 14 and a ferrule 16 wherein the fastener member has a perpendicular shoulder 36 with respect to a longitudinal axis of the pipe 18 and abuts a squared shoulder section 42 of the ferrule to prevent the ferrule from being squeezed out of the compression coupling 10. The ferrule has outwardly radially extending flanges to retain it within the fastener member. The ferrule also has radially inwardly extending teeth that bite into the pipe to prevent the pipe from backing out. The ferrule also has an axially inner section 40 with notches 62 formed therein. The end 40 is deformed by a camming surface 28 on the body 12 to crimp the pipe 18 as the fastener member 14 is secured to the body member 12. The axially inner section 40 forms a right angled shoulder that abuts the pipe and prevents the pipe from being easily pulled out of the coupling.

Abstract: A valve assembly comprising a temperature responsive servomechanism adapted to combine hot and cold water under pressure to produce a constant preselected temperature of water at an outlet.The valve assembly comprises a housing having a valving cavity, a hot water inlet leading to the valving cavity, a cold water inlet leading to the valving cavity, and a mixed water outlet passageway leading from the valving cavity. A valve member translates in the valving cavity and divides the cavity into two auxiliary chambers. A passageway through the valve member allows fluid to flow from each of the inlets to the outlet passageway at a rate that varies as the valve member translates. Passageways in the valve member permit a portion of the mixed water to flow into the auxiliary chambers. An auxiliary passageway is provided between each of the auxiliary chambers and the outlet passageway. A temperature responsive element is provided within the outlet passageway.

Abstract: A packer for a down hole oil well includes an inner mandrel assembly having an upper outer sleeve assembly that includes the hold down mechanism and upper packer seals with a piston on the underside of the packing seals to be pressure responsive and to deform the seals in response to pressure within the well string. Furthermore, a lower outer sleeve assembly has packing elements that are deformed and a setting mechanism to allow the packer to be set in a position within the well casing. Upper and lower unloading valves allow for fluid the bypass the packers when the packer is retrieved upward through the well casing.
