  • Patent number: 4362619
    Abstract: An improved continuous centrifugal machine includes a rigid base structure, a bearing housing, a normally vertical basket shaft journalled for rotation on bearings in the bearing housing, an upwardly open frusto-conical centrifugal basket secured to the upper end of the basket shaft for rotation therewith, a stationary curb wall mounted on the base structure and surrounding the basket, buffering assemblies for resiliently mounting the bearing housing on the base structure to permit gyration of the basket, and a motor mounted to one side of the curb wall and connected by an improved system to the lower end of the shaft for rotating the basket. The system for connecting the motor to the basket shaft comprises a support shaft mounted in a fixed position beneath and substantially aligned with the basket shaft. A belt pulley is supported for rotation on a bearing carried on the support shaft and a driving belt connects the belt pulley with a second pulley driven by the motor.

  • Patent number: 4343707
    Abstract: Method and apparatus for separating out solids suspended in flowing, substantially pure water systems such as those systems found in steam power plants. The apparatus includes a helical conduit which directs the water and suspended solids in a helical flow path that subjects the solids to a centrifugal force. The apparatus further includes magnets mounted around the helical conduit for subjecting the solids suspended in the water to a magnetic force. The magnetic force and the centrifugal force co-act to direct the suspended solids out of one of two outlet nozzles. The remaining water with the suspended solids removed flows out of the other outlet nozzle.

  • Patent number: 4337790
    Abstract: Disclosed is a filter for use in a faucet of the type having a removable cartridge member receivable in an underbody member, the cartridge member carrying a cam member, at least one cam follower member and a valve member actuated by the cam follower member upon movement of the cam to control fluid communication between a spout and a source of water. The filter member is removably attached to a projection on the valve member and moves with it within a passage in the underbody member through which water flows from the source. By this means, large particles are prevented by the filter from entering the faucet. The filter comprises an inner annular member, an outer annular ring member, and a plurality of flat web connecting members extending radially between the inner and outer annular members. The inner annular member has a through hole which tapers from a first diameter to a second diameter so that the inner annular member can be forced over a head portion on the projection whereafter it is latched thereon.

  • Patent number: 4337136
    Abstract: A pair of electrodes formed of silver-copper alloy depend from the bottom wall of a floating container. The latter is arranged to float on the surface of a body of water to be treated and contains a battery which is connected in circuit with the electrodes through a timer switch and a current reversing switch. Passage of a direct current across the electrodes ionizes the water and the silver and copper ions destroy and prevent the growth of bacteria and algae.

  • Patent number: 4332682
    Abstract: A system for collecting products dumped on the surface of a mass of water includes cages to be arranged at the sides of a tanker. Each cage is preferably prismatic in shape. The height of the cages is such that when the tanker is at ballast, the lower parts of the cages will be submerged while the upper parts will be above the maximum loading line of the tanker. The cages are fastened to the sides of the tanker by freely rotating connection points. In the interiors of the cages is housed a series of floating suction pump inlet members or housings, likewise prismatic in shape, having appropriate dimensions to permit a great sensitivity to the least fluctuating movements of the liquid surface. The complete face of each suction pump inlet member, which is oriented in the direction of travel of the tanker, is provided with an opening which has a height such that the lower edge thereof will be positioned below the floating line of the suction pumps at an approximate depth of 0.01 meter.

  • Patent number: 4330412
    Abstract: A hydrotherapy device, such as a spa, whirlpool or jet stream exerciser is connected to a closed water circulation loop having a drain, a pump, a heater, a filter, a valve controlled filter bypass and injection nozzles. The pump is equipped with a close-coupled drive motor having two sets of stator windings for allowing the selection of one of two motor speeds to achieve improved operation and greater efficiency of the hydrotherapy device. A low motor speed is selected during periods of non-use, at which time the filter device is connected into the circulation loop so that a low water circulation rate is provided in order to maintain purity of the water. During periods of use, a higher motor speed is selected and the filter is bypassed to provide a high water circulation rate and high velocity water injection into the hydrotherapy device. Reduced motor speed during periods of non-use results in substantial energy savings and a reduction in the noise generated by the device.

  • Patent number: 4330402
    Abstract: Apparatus for sampling and disposing of water which has been separated from a water polluting element, the latter being lighter than the water. The apparatus includes an elongated upright caisson or pile which is disposed in a body of water, and which is adapted to contain a quantity of the water as well as the pollutant element. A submerged sampling apparatus is positioned at the lower end of the caisson and is actuated by gas pressure controlled from the water's surface to periodically withdraw a measured sample of the pollutant free water to assure its purity.

  • Patent number: 4325826
    Abstract: Oil sweeper method and apparatus including an elongated structural framework adapted to be towed transversely across the surface of water bearing an oil film contaminant, the framework supporting a pair of longitudinally extending, parallel vertical screens, wherein the forwardmost screen relative to the direction of sweeping motion is constituted of multiple panels pivotally attached to the framework for swinging movement about vertical swinging axes, and the rearward screen is water impervious. When the panels of the forwardmost screen are pivoted they define channels therebetween for diverting surface water and floating contamination such as oil in a lateral direction towards a skimmer disposed at one end of the sweeper apparatus. The rearward screen assists in further deflecting the water and oil towards the skimmer after they have traversed the channels between the pivotable panels.

  • Patent number: 4320008
    Abstract: An apparatus for moving solid material and liquid from a floor into a solid material tank and a liquid tank. The floor has longitudinal sections that slope downwardly to a longitudinal slit open to a chamber located below the floor. A scraper pivotally connected to a frame moves solid material from the floor into the solid material tank when the frame is moved toward the solid material tank. A vertical plate attached to the frame extends through the slit into the chamber. A plate pivotally attached to the vertical plate pushes liquid in the chamber into the liquid tank when the frame is moved toward the liquid tank. A winch and rope attached to a connecting fitting located in a mount on the frame selectively moves the frame in opposite directions over the floor. The fitting has limited movement relative to the frame and engages the scraper to raise the scraper above the floor when the frame is moved toward the liquid tank whereby solid material is not moved when the scraper is raised.

  • Patent number: 4320007
    Abstract: A centrifuge filter has a sieve drum normally rotated about its axis and normally fed internally with a filtrand that is separated when the drum rotates into solids lying on the inner surface of the drum and a filtrate that passes radially outwardly through the drum. A pusher plate is axially displaceable in the drum and has an outer edge closely juxtaposed with the drum's inner surface so that it can scrape solids from the surface. A cylinder is rotationally fixed to the drum and has a cylinder chamber that is axially subdivided by a piston into a front compartment and a rear compartment. This piston is jointly axially displaceable with the pusher plate and is axially biased backward. A liquid is introduced into one compartment to fill it as it rotates so that the liquid will be forced radially outward by centrifugal force and will urge the piston axially forward. This liquid is periodically drained off so that the force it exerts is less than that of the biasing means.
