  • Patent number: 4834836
    Abstract: An apparatus for pollution control in treating the effluent employs an evaporation stage where the effluent solutions are heated to 150.degree. Fahrenheit. The resulting steam and vapors are then oxidized by photoysis and photolytic catayzed ozone before the steam and vapors are discharged through a rubber coated dryer duct. The apparatus is comprised of two main units, a lower evaporation sump unit and an upper photolysis and blower unit. The sump is manually filled through a port located in the top of the blower unit. The operator will then switch the main power switch to "ON" and activate the system. This includes activation of an ultraviolet lamp, blower and heat belts. The heat belts are fixed around the base of the sump.

  • Patent number: 4808201
    Abstract: A method and apparatus for sealing and affixing connectors to membrane tubing reinforced by braided netting and used for drying of fluids employs mechanical fusion of the material of the braid or of an overlay formed of thermoplastic material (or a combustion of both) to produce the mechanical seal between the tubing and a connector. The seal includes an inner tubular insert (which may be formed of stainless steel, ceramic, or glass). The insert is placed in the end of the drying tube. The connector is fused to the tube by applying high temperature and pressure to the area of the tubing over the insert. This causes fusion of either the braiding material itself or fusion of a thermoplastic overlay placed over the end of the tubing surrounding the insert.

  • Patent number: 4640769
    Abstract: The apparatus uses a combination of technologies for treatment of hazardous and nonhazardous liquid wastes. The first treatment step is an evaporation stage where the liquid wastes are heated. The resulting steam and vapors are then oxidized by photolysis and photolytic catalyzed ozone before they are condensed. The steam and vapors are then condensed and the condensate is passed through a column of activated carbon. The activated carbon absorbs any unoxidized Chemical Oxygen Demanding (COD) species and aids in the control of any odors which may be emitted in the evaporation stage.

  • Patent number: 4276024
    Abstract: A system controls the flow of a drive fluid for driving a tool on a handpiece. The system comprises a drive fluid line communicating with the handpiece and a drive fluid control motor for controlling the flow of the drive fluid in the line. Control means is operatively associated with the fluid drive motor control, and responsive actuation means on the handpiece which is manually engaged by the finger of the user. Upon actuation, the control means controls the drive fluid control to provide initially a flow of the drive fluid such that the handpiece is powered at an initial level, the fluid motor then being continuously responsive for a time interval substantially coinciding with the operation of the actuation means by the finger of the user for altering the level of drive fluid flow to vary the power availabile in the handpiece. The level of flow when the finger releases the actuation means is then maintained until the actuation means is again actuated whereupon drive fluid flow is stopped.

  • Patent number: 4271701
    Abstract: The pressure difference across a pneumotach restriction is sampled with a gas chopper connected across a pressure difference detecting transducer. The gas chopper alternates the pressures backward and forward in application to the transducer so that the latter develops an AC sampling signal, the strength of which is related to flow. This AC signal is sampled in synchronism over intervals having a duration related to the power line frequency to develop an integrated value of the pressure difference free of drift caused by power line interference. The resultant signal is smoothed and summed in alternating response at double the gas chopper sampling rate to give a smooth output which is then multiplied by a linearizing circuit to obtain a flow signal which is proportional to the pressure difference. Specific gas flow structures and electronic sampling circuitry are disclosed.

  • Patent number: RE30536
    Abstract: An ultrasonic hand-held cleaning device having a housing enclosing a casing, an energyzing winding about the casing, and a fluid conduit attached to the interior of the casing. A sleeve is insertably mounted into the end of the casing, and acts to support a connecting body at a spaced distance within the sleeve so as to form an annular space in fluid communication with the casing. A vibrator is attached at the casing end to the connecting body and is therefore located in the casing opposite the energyzing winding. A cleaning tool is attached at the other end of the connecting body. In one version fluid moving through the annular space is sprayed out an annular nozzle around the tool which is itself vibrating ultrasonically as a result of reverbretory vibrations induced by the vibrator. In a second preferred embodiment the connecting body has a ring at its nodal point, the sleeve being cut out to accommodate the ring and having two longitudinal slots for the passage of fluid.
