Abstract: A metered water control system inlet tube (24) receiving water conducting water into the interior of the tank to a diverter. A diverter (48) channels the flow to cause mechanical motion responsive to the channeled flow. A control valve (66 and 60), responsive to a mechanical switch, opens and closes access of the water from the inlet tube to the diverter. A mechanical switch (124, 112, and 114), responsive to flow of water from the diverter, closes the control valve automatically when a predeterminable volume of water flows through the diverter. A discharge tube (20 and 24) receives water from the diverter to discharge the water into the tank. An actuator (158 and 162) linked to a flush arm of the toilet and linked to the mechanical switch causes the switch to open the control valve to allow the pre-determined volume of water to flow into the discharge tube.

Abstract: A method and apparatus for detecting unauthorized or accidental entry of an object into a body of water is disclosed, wherein the frequency or frequency range of sound waves in a body of water generated by the entry of the object into the body of water is determined. Then the sound waves having the frequency generated in the body of water are detected and an electrical output waveform representative of the amplitude of the sound wave in the frequency is generated. The amplitude of the electrical output waveform is subsequently averaged, so that an alarm signal is generated when the amplitude of the electrical output waveform exceeds the averaged amplitude by a predetermined value in a predetermined period of time. Once the alarm signal is generated an alarm is activated.

Abstract: A construction unit and method for forming an exterior surface on a support framework. The construction unit includes a plurality of tiles for forming a finishing layer on the support framework. Mounting brackets are attachable to the support framework to position the tiles at a distance from the support framework to define an internal cavity between the support framework and tiles. An adhesive, filler material is introduced into the internal cavity to bind together the support framework, the tiles and the mounting brackets to form a consolidated construction unit. In a stud frame building, modified mounting brackets can be used that position the tiles directly against an exterior face of the stud frame wall. The adhesive, filler material contacts and binds the tiles through the openings in the stud framework.

Abstract: A kit that includes a universal flapper and water saver valve stop for the fluid outlet of sanitary flush tanks utilizing a flat, thin, doughnut shaped gasket mounted on alternate supports, wherein the use of one support allows the doughnut shaped gasket to maintain its relatively flat configuration as in standard flapper valves, and the use of the alternate support stretches the doughnut shaped gasket to form a truncated cone, the dimensions of which closely follow those of standard ball valves, and the support structure for the valve stop includes at least two connecting devices for alternately connecting the valve stop to the different types of connecting assemblies found in standard flush tanks.

Abstract: A device for metering the flow of water into the tank and bowl of any currently known tank toilet and providing a positive shut-off of the flow. When the toilet handle is turned, a linkage rotates a cam to force a stopper from its seat thereby commencing water flow. Water flows through a flow channel to be directed by a flow nozzle past a water wheel imparting a rotation thereto. The water wheel is gearably linked to the cam thereby rotating the cam. When the cam has rotated to position a cam repeat over the stopper stem, the stopper is reseated by the pressure of the water and water flow ceases. The distribution of flowing water between tank and bowl can be changed by altering the structure of a bowl fill assembly. The bowl fill assembly and a tank fill tube are attached to the outlet by a right angle manifold. The amount of water flow permitted is a function of the number of cam notches and flow nozzle size.

Abstract: A gas fire space heater which can be an insert for an existing fireplace or a free standing unit is described. The device consists of a gas burner with radiants disposed within a housing. The products of combustion are collected in a first plenum, directed through a concertina heat exchanger into a second plenum, and from the second plenum up a flue. Air to be heated is collected by a blower and circulated countercurrently to the products of combustion through the heat exchanger, around the housing, and into the space to be heated. Air to be heated is supplied to the blower from an outside vent, and an inside vent. The outside vent is controlled by a one-way suction damper and the inside vent is controlled by a manual damper. The two vents form a T at the fan inlet and control of the manual damper then controls the amount outside and inside air supplied to the blower.

Abstract: A low voltage switching power supply designed to be compact and efficient for use with very high speed integrated circuits (VHSIC) has an innovative output transformer. Designed for use at greater than 50 KHZ (typically 100 KHZ) the transformer is box-like in shape of high permeability ferrite material having one to four rectangular channels containing the primary and secondary winding. The secondary is electroplated copper with very low resistance while the primary is copper tape of some sixteen nominal turns. The power capability is 500 Watts with the output at 5 Volts DC or less and has an efficiency of greater than 98 percent. Up to three transformers can be paralleled to give a total output power of 1500 Watts.

Abstract: A device for converting an existing fireplace to an efficient space heater to fully utilize the heat generated by a fire therein without losing the aesthetic effect thereof is disclosed. The device includes a plenum chamber adapted to rest on the bottom surface of the fireplace, said chamber having a damper controlled draft inlet opening into the existing ash dump pit. The ash pit then serves as an air inlet conduit for air to be heated, and outside air may be supplied thereto by a fan. Pipes extend from the interior three edge portions of the chamber upwardly and around the fire wall and terminate framing the upper and side portions of the fireplace opening. A conventional fire grate is disposed on the upper surface of the chamber surrounded on three sides by said pipes. Air admitted to the plenum chamber then circulates through the pipes to be heated by a fire on the grate, and is then expelled into the room.

Abstract: An efficient zero clearance fireplace heating device is disclosed. The device includes a conventional metal firebox having closeable glass doors and a flue adapted to communicate with a chimney. The sides and bottom of the firebox are enclosed with mutually spaced metal walls to form a plurality of interconnected chambers for circulating either room air or outside air therethrough. A portion of the circulated air is returned to the room through a vent and a portion is admitted to the firebox for combustion air. The combustion air is initially directed across the interior surface of the glass doors to minimize blackening thereof by smoke from the fire. Baffles may be provided between walls of the interconnected chambers to provide a labyrinthian series of passages for air circulated therethrough whereby heat is exchanged between the walls and the circulating air so that the outside surfaces of the device remain sufficiently cool to permit installation adjacent combustible structural members.
