  • Patent number: 4264451
    Abstract: Hydrogen sulfide is effectively removed from potable water by the combined action of first chlorinating the water and then passing the chlorinated water through a bed of activated carbon. Chlorine is added in large doses to potable water containing dissolved hydrogen sulfide to convert substantially 90% of the hydrogen sulfide to sulfates. The chlorinated water containing residual hydrogen sulfide is then passed through a bed of activated carbon. Chemisorbed nascent oxygen in conjunction with the activated carbon catalytically affect breakdown of the remaining sulfide compounds into elemental sulfur.

  • Patent number: 4260901
    Abstract: A system for converting the mechanical energy in the wave motion of a body of water into electrical energy. A frame is fixed with respect to the wave motion of the water. A flotation element is buoyantly supported by the water and constrained to follow only the vertical component of the wave motion. The motion of the flotation element is transferred to an electrical generating device which includes a device for producing electromagnetic flux and electrical coils. The motion of the flotation element causes relative motion between the flux-producing device and the electrical coils thereby generating an electromotive force. A positioning subsystem is provided for moving the electrical generating device relative to the flotation element when the average depth of the body of water changes so as to maintain a symmetrical relative motion between the flux-producing device and the electrical coils.

  • Patent number: 4256181
    Abstract: A fire extinguishing system is automatically actuated in response to flames from a fire on the upper surface of a stove having a vent hood. A pressurized fire extinguisher includes a lever actuated valve spring biased to the open position and contains a supply of fire extinguishing material. A discharge manifold extends between the valve of the fire extinguisher and a plurality of nozzles which are positioned within the vent hood to distribute the fire extinguishing material over the upper surface of the stove when the valve is released into the open position. A fusible link secures a strut which maintains the valve in a closed position. A fuse extends from an area above the upper surface of the stove to a capsule of gun powder which surrounds the fusible link. A fire in the stove top area ignites the exposed end of the fuse which controllably transfers fire to the capsule of gun powder.

  • Patent number: 4255936
    Abstract: The heating system of the present invention includes a compressor for compressing and heating refrigerant. The pressurized, heated refrigerant is passed through a first heat exchanger which is coupled to a container of water. A pump circulates water from the container through the first heat exchanger to transfer heat from the refrigerant through the heat exchanger to the water. This heat exchange process cools and condenses the refrigerent from a gas to a liquid as the water is heated. The liquified refrigerant is transferred to a coaxial earth tap which includes an inner passageway for transferring the refrigerant from the upper end to the lower end of the earth tap and a restrictor positioned at the lower end of the tap for vaporizing the refrigerant.

  • Patent number: 4250128
    Abstract: Annular magnets, primarily for motor stators, are centrifugally cast from particulate materials and synthetic plastic materials. Iron particles and ferrite particles stratified during the spin casting procedures so that the former provide an outer stratum that serves as a yoke in the permanently magnetized structure. The anisotropic ferrite particles are magnetically oriented during casting by a rotating center magnet with the aid of bucking magnets that also rotate and serve to confine the field of the center magnet to the cavity area. Apparatus for carrying out the process is disclosed and includes means for introducing the plastic and particulate materials to the mold cavity while the mold is rotating as well as mold arrangements that facilitate material introduction by the creation of reduced pressure conditions in the cavity during the rotation of the mold.

  • Patent number: 4248305
    Abstract: A system and method of moving near-surface water to a deep water aquifer at a high rate of transfer and with no external energy sources, and which additionally generates excess energy available for other uses. The system comprises at least one deep well into the deep aquifer and one or more shallow wells into a near-surface water table aquifer having siphon pipes from the shallow wells to the deep well. Siphon action is initiated resulting in a continuing flow of water from the shallow wells to the deep well. A water-driven turbine is disposed in the deep well above its tail water level and below the lower end of the siphon tubes. The water flow operates the turbine and the turbine shaft drives an external vacuum pump. Each shallow well has a closed top plate, and suction from the vacuum pump is applied through the top plate, holding the water level above its normal point increasing the draw down.

  • Patent number: 4243050
    Abstract: An apparatus and related method for implanting pacemaker electrodes and similar devices within a patient include an introducer with a tapered end adapted to extend into the patient's body, and a hollow, tubular sleeve having a first portion with an inner dimension greater than the outer dimension of the introducer and a second portion at one end of the sleeve which extends parallel with the introducer and in close engagement therewith, with a gradual taper along the sleeve between the first and second portions. The sleeve has a longitudinal slit along the first portion and through the taper, but short of the forward extremity, to permit the sleeve to be peeled away from the pacemaker electrode after introduction. The introducer and sleeve include corresponding hub and flange arrangements which provide a means for locking the two elements together to prevent inadvertent motion of the sleeve with respect to the introducer as the two elements are being inserted into the patient.

  • Patent number: 4243464
    Abstract: A laminating machine and the method incorporated therein includes a pair of opposing and substantially parallel cylindrical steel rollers defining a continuous pressure line between the outer cylindrical surfaces thereof. A sheet is fed between the rollers in a first direction substantially transverse to the pressure line, and a film to be laminated is fed onto the sheet surface and with the sheet in the first direction. A fluid pressure cylinder-lever arm arrangement is provided with one of the rollers for applying relative pressure between the two rollers along the pressure line during passage of the film-sheet combination therebetween, the pressure being in an amount sufficient to compress the sheet to effect complete bonding of the film to the sheet surface, but in an amount less than that which causes structural damage to the sheet. The outer surface of one of the rollers is heated during the laminating process.
