  • Patent number: 4161182
    Abstract: An extensible sanitary hose used for the transfer of sewage from a holding tank to a sanitary facility may be cleaned and stored by the use of a combination holding and cleaning device which is fabricated from an elongated hollow cylinder having a number of openings extending laterally therethrough distributed along its length, such cylinder being open at one end and closed at the other end. A circular retaining member is mounted to the cylinder adjacent its closed end for supporting the bottom end of the hose for restraining the hose in place thereon, and a locking ring is removably mounted to the cylinder adjacent its open end.

  • Patent number: 4150700
    Abstract: A method and system are provided for handling a flowable product when transferring same from one bulk container, such as a railroad tank car, to a second bulk container of smaller capacity, such as a tank truck. A fitting is removably mounted on a valved product discharge port provided on the one container. The fitting includes an inlet for a compressed fluid. A removable duct section connects the fitting to a valved product inlet port provided on the second container. The interior of the first container is charged to a predetermined pressure by the compressed fluid while the valved discharge port is closed. The product is transferred from the charged one container to the other container through the duct section when the valved ports of both containers are opened.

  • Patent number: 4063317
    Abstract: A device for unclogging blocked pipes, tubes, drains and other conduits employing a source of compressed gas such as a CO.sub.2 cartridge or air compressor and a secondary source of compressed gas and/or liquid. A compressed gas storage chamber receives and holds the compressed gas until a desired predetermined pressure is reached at which time a valve is opened allowing the gas under pressure to flow to the conduit to be unclogged. Simultaneously, and if required, a secondary source of compressed gas and/or liquid can be led into the conduit to be unclogged, downstream of the storage chamber release valve. An automatic safety gas relief valve is also disposed downstream of the storage chamber release valve for safety.

  • Patent number: 4062403
    Abstract: An improvement in a pump-down tool for use in sand washing operations is provided. The pump-down tool includes a tubular member having a locomotive member positioned thereabout and a fluid passageway positioned therethrough and a sand washing tool positioned in fluid communication with the lower end of the tubular member as positioned for use. The well has positioned therein a first and second tubing member with the first and second tubing members being in fluid communication at a junction near their lower ends so that the pump-down tool may be urged along the length of the first tubing member toward the junction by pumping fluid sequentially through the first tubing member, the junction and the second tubing member. The tool is recovered by pumping fluid in the opposite direction.

  • Patent number: 4061571
    Abstract: A water inlet cleaning means for Marine Craft and fluid supply systems that will clean out the inlet pipe and inlet fittings of foreign matter, allowing liquids to flow. The water inlet device includes adapters that attach to the inlet pipe and new water inlet devices responsive to signal means, to pressure means that operate manually or automatically indicating a clogging condition in water pipes, outboard and inboard-outboard motors and inboard motors and each of the water inlets are kept free of clogging by the subsequent operation of these safety devices.

  • Patent number: 4059858
    Abstract: Apparatus for clearing drain lines includes an appliance which may be held in sealed engagement over a drain opening and actuated with a sudden burst of gas pressure. The appliance includes a pressure chamber which can discharge into a sealing ring and which for each operation is initially closed off from the sealing ring by a rupturable metal diaphragm. While the appliance is held by hand with its pressure ring firmly sealed around the drain opening, gas pressure is increased in the pressure chamber until the diaphragm suddenly ruptures to release the compressed gas into the drain with a sudden hammer-like action. The gas pressure may be supplied from a pressure can or by pump. This metal diaphragm may be a conventional jar-cap as used for home canning, except accurately scored to rupture at a predetermined pressure.

  • Patent number: 4051839
    Abstract: A hot water heater having a heating tank and a superjacent basin for receiving cold water to be delivered to the tank. A duct is provided leading from the basin into the tank for transferring water from the basin to the tank. A heater is provided for heating the water in the tank. Structure is provided in the duct for breaking up lime which may form at the upper level of the water in the tank and cut as a result of a continued heating of the water therein. The lime breakup structure includes a float and a retaining cage for controlling the movement of the float during delivery of cold water from the basin through the duct to the tank. The cage and float are removably carried in the hot water heater for facilitated installation and maintenance.

  • Patent number: 4030711
    Abstract: Method and apparatus for flame hardening the inner wall surface of tube bends of a circular configuration wherein either a flame hardening burner is passed longitudinally through the internal cavity of a tube bend which is mounted in a fixed position, or alternatively the tube bend is moved over a stationary flame hardening burner. This relative movement between tube bend and burner is effected along a circular path corresponding to the longitudinal center line of the tube bend. Subsequently to flame hardening the heated inner wall surface of the tube bend is quenched with cooling water discharged from water sprinklers disposed downstream of the flame hardening zone. During flame hardening and quenching the tube bend is continuously maintained in positions such that the quenching water may leave the tube bend by gravity.

  • Patent number: 3991797
    Abstract: A device for cleaning a rotating vessel filling machine, especially bottle filling machines, of the one-chamber type with a feeding pipe for feeding a liquid or gaseous cleaning medium into filling containers and filling elements. Each of the filling elements includes a housing closure with an outlet that leads to an exhaust and that is closed and opened by a control valve. The filling elements are connected to annular passage means through vessel pressure relieving means. The annular passage means are connected through conduit means both to be brought into communication with a cleaning substance feeding conduit and also to be disconnected therefrom.

  • Patent number: 3958584
    Abstract: A mechanical self-timing valve is connected between a source of sanitizing solution and a milking machine to sanitize the milking machine between each milking operation. Initiation of the valve cycle is accomplished by pressing a button-type plunger to admit pressurized fluid to a cylinder and drive the piston and valve poppet to a flush position. Return of the poppet and piston to a drain position is resisted by pressurized fluid in the cylinder which is permited to bleed through a long, large diameter helical bleed conduit that winds around the plunger. In flush position, a sanitizing solution is directed through the valve, through a flexible milking line and through the claw and teat cups of the milking machine. In drain position, flow of sanitizing solution is blocked and the disconnected milking machine is gravity drained of remaining sanitizing solution, partly through the disconnected teat cups and partly through a valve drain port.

  • Patent number: 3937404
    Abstract: A drain clearance device comprising a length of flexible hose having at one of its ends means for connecting it to a source of water under pressure and at the other end a nozzle of elliptic contour longitudinally thereof and of a size to fit into a drain pipe. Said nozzle has four circumferentially spaced, slot-shaped orifices in the flanks of its rounded front end that are adapted to emit flat jets of water under increased pressure forwardly at an oblique angle against the inner surface of the drain pipe to dislodge and flush away any foreign matter that may have accumulated on the wall of the pipe and impede the free flow of water through the pipe. Intermediately of its ends the hose carries slidably mounted thereon means that may be manipulated to close the space around the hose to block back flow of water to the entrance opening of the drain during operation of the device.
