  • Patent number: 5785902
    Abstract: A liquid vaporizing apparatus includes a container for holding a liquid at a constant temperature with a temperature adjustment unit and a gas that does not react with the liquid is bubbled through the liquid in the container to vaporize the liquid. The container for holding the liquid has an internal space above the liquid and a second temperature adjustment unit for controlling the temperature of the internal space separately from the temperature of the liquid in the container. Since the internal space is maintained at a constant temperature, higher than the temperature of the liquid, the quantity of the vaporized liquid produced is stable.

  • Patent number: 5785899
    Abstract: An apparatus for aerating a liquid, having a surface, employs a motor having a rotating member and a non-rotating member. A shaft is coupled to the rotating member of the motor. Also coupled to the shaft is an input of a planetary gear assembly, comprising stationary upper portion and a rotatable lower portion. The rotatable lower portion is coupled to the axial section of an aeration rotor so that as the aeration rotor is placed in the liquid, a portion of the planetary gear assembly is in contact with the liquid, thereby facilitating cooling of the planetary gear assembly by the liquid. The planetary gear assembly also comprises a seal between the stationary upper portion and the rotatable lower portion disposed above the liquid and disposed above substantially all of the oil in the planetary gear assembly so as to inhibit spillage of oil from the planetary gear assembly into the liquid if the seal fails.

  • Patent number: 5783069
    Abstract: A packing element for use as a biofilm support in the biological processing of liquids. The packing element has a hollow cylindrical body having a plurality of helical blade members extending generally radially from the cylindrical body. A plurality of such packing elements are placed in a vessel. When liquid and/or gas flows over them, they tend to rotate causing local turbulence with resulting improvement in diffusion of gas and/or substrate to and from the biofilm, giving enhanced rates of liquid processing.

  • Patent number: 5776378
    Abstract: An apparatus for applying scent to clothing has an enclosed compartment having a top, bottom and side walls. A horizontal perforated shelf extends across the compartment and divides the compartment into upper and lower portions. A closeable access opening is located in the side walls of the compartment for placing articles of clothing on top of the shelf. An air circulation conduit connects the upper and lower portions of the compartment. A fan is connected to the conduit for moving air therethrough from the upper portion to the lower portion of the compartment. A scent cartridge is in communication with the compartment in the path of air passing therethrough so the passing air will pick up the scent of the scent cartridge whereupon the scented air will move into the lower portion of the compartment, thence through the shelf and articles of clothing, and thence into the upper portion of the compartment and back into the conduit.

  • Patent number: 5776377
    Abstract: A metering block having at least one removable jet cartridge is provided for replacing the physical and functional operation of the standard metering block for use with the carburetor and fuel bowl of a conventional internal combustion engine. The metering block has openings in the top of the block at an angle from vertical for receiving the jet cartridges. The jet cartridge is configured to utilize the standard fuel jets used with the standard metering block to maintain the same fuel metering characteristics as the standard metering block. The jet cartridge is positioned at an angle within the metering block to allow the jet cartridge and fuel jet to be removed and replaced from the carburetor without the need to remove the fuel bowl or metering block from the carburetor or fuel to be drained to obtain access to the fuel jet as is the case in the standard metering block design.

  • Patent number: 5772927
    Abstract: In a first aspect, a carburetor fuel adjusting device that facilitates control of the quantity of fuel that flows from the fuel chamber to an air intake port of a carburetor by making it possible for the user to adjust an adjustment valve within the limits defined by emission control regulations. The carburetor fuel adjusting device has a cap having two appendages, and an engagement area to engage a valve extension of the fuel adjustment valves of a carburetor. The cap is retained by the retainer in either a disengaged position, or an engaged position wherein the engagement area of the cap becomes attached to the valve extensions. In the engaged position, the adjustment valves can be turned in unison with the cap within a range formed by the angle between the appendages which, when rotated, abut against stoppers.

  • Patent number: 5772928
    Abstract: A valve assembly is provided for controlling the flow of fuel to the fuel chamber of a carburetor. The valve assembly includes a housing and a needle. The housing includes a side wall defining an inlet, an outlet in fluid communication with the inlet, and an interior region between the inlet and outlet. The needle is received in the interior region of the housing for movement therein between a closed position blocking the flow of fuel between the inlet and the outlet and an open position allowing the flow of fuel between the inlet and the outlet. The needle includes a post and a skirt fixed to the post. The skirt extends outwardly from the post and cooperates with the side wall to restrict the flow of fuel therebetween dampening the movement of the needle relative to the housing so that the needle moves with the housing when the housing vibrates in response to the operation of the engine.

  • Patent number: 5766519
    Abstract: An absorber for absorbing a vapor into a sorbent liquid comprised of a sequential plurality of highly effective and intensified locally cocurrent sorptions, but with non-cocurrent flow of vapor and liquid between the individual sorptions. The structure containing the locally cocurrent upflow is preferably comprised of enhanced heat transfer surface, making the sorption diabatic, further enhancing the intensification, and improving the sorption efficiency. Referring to FIG. 1, vertical cylinders (1) and (2) form an annulus which is divided into multiple compartments by partitions. Vapor is injected into the bottom portion of each compartment by injection ports (10), resulting in cocurrent upflow absorption. The compartments are pressure equalized with a common vapor space via equalization ports (6). This approach to absorption can be accomplished in a vertical cylindrical annulus as described above, in a horizontal cylindrical annulus, in plate fin exchangers, and others.

  • Patent number: 5759451
    Abstract: A humidifier is disclosed having operation, speed, and humidity control for the distribution of humidified air. The humidifier contains a multiplicity of air moving devices, e.g., fans, to enable large quantities of humidified air to be distributed in an area or conversely, only a small amount of humidified air to be distributed in the area in order to maintain the humidity level already achieved. The humidifier requires only the power necessary to achieve or maintain the level desired without excess use of power. At least one operating control is used to selectively operate one or all of the air moving devices, and at least one speed control is also preferably used with the operating control for selectively increasing or decreasing the speed of one or all of the air moving devices. Along with the operating control and speed control, a humidity control may pre-select humidity between a predetermined minimum and maximum.

  • Patent number: 5759233
    Abstract: An air pollution control system incorporating a venturi scrubber and a method of cleansing a particulate-laden, contaminated gas flow are disclosed. Spray nozzles are used to introduce optimized droplets of a scrubbing liquid into the venturi to maximize particle collection efficiency. The present invention discloses automatic control systems which adjust the venturi as the properties of the effluent gases change. For example, in one embodiment, the spray volume and/or droplet size is adjusted as the particle concentration changes. In another embodiment, the spray volume is increased as the volume of effluent gas decreases.
