  • Patent number: 5207808
    Abstract: A canister for adsorption of evaporated fuel in an automobile. The canister operates to decrease leakage of the evaporated fuel when the atmosphere temperature rises or the canister is left as it is for a long time. To this end, the canister according to the invention comprises a first container provided in adjacent to an inlet for evaporated fuel and incorporating therein a liquid-phase component adsorbent, a second container provided on the downstream of the first container and on the side or the top of the first container and filled with an adsorbent, and a third container disposed between the second container and an atmosphere port and filled with an adsorbent. Further, the first, second and third container are integrally formed. With such structure, liquid-phase components of the evaporated fuel are collected by the adsorbent in the first container so that a life span of the adsorbent in the second container can be elongated.

  • Patent number: 5207810
    Abstract: A gas separator for a submersible centrifugal pump for a well separates gas from liquid components of the well fluid. The gas separator has a rotatably driven rotor. The rotor has an outer cylinder, an inner hub and a longitudinal vane that extends between the inner hub and outer cylinder. Notches are formed in the upper edge of the vanes. A discharge member, mounted above the rotor, has a depending skirt that extends into the notches. This defines a separate inner flow path for gas to flow out of the separator into the well. The unseparated portions of the well fluid flow in a clearance between the skirt and the housing into a pump intake. Supports extend out from the discharge member for securing the discharge member in the housing.

  • Patent number: 5206038
    Abstract: A wedge type locking member (27) is brought into contact with a first piston (12) for clamping by means of a pushing spring (28). Thereby, the first piston (12) is prevented from returning from the clamping position (X) to the unclamping position (Y). The locking member (27) is provided with two pressure receiving surfaces (F)(S) having substantially equal areas. A fluid pressure within a first actuation chamber (13) for clamping acts upon these pressure receiving surfaces (F)(S). The locking condition of the locking member (27) is cancelled by means of a second piston (39).

  • Patent number: 5203893
    Abstract: A filter case having open opposite ends is disposed with one of the open ends thereof facing an air exit formed in the side wall of the housing of an electrophotographic apparatus, and a filter element holding frame having an upper opening through which an ozone filter element is inserted therein is supported pivotally at its lower end on the lower portion of the filter case for turning about a substantially horizontal axis so as to be fitted in the filter case. In changing the ozone filter element, the cover is opened, the filter element holding frame is turned about the substantially horizontal axis to expose the upper opening thereof outside the filter case so that the ozone filter element can be taken out through the upper opening from the filter element holding frame. The wide, open upper space in the housing facilitates the filter element changing operation.

  • Patent number: 5200091
    Abstract: The process to recover salt from brine waste water. By using the differentiation in the absorption and transmission of the infrared beam between sodium chloride or potassium chloride and organic compounds, the method of irradiating the salt crystals with infrared beam is used to vaporize and disintegrate the organic compounds on their surfaces. This method provides more economic and effective means of purifying salts from brine waste water containing high concentration of organic compounds.

  • Patent number: 5191940
    Abstract: An oil/gas separator is disclosed that can be utilized to return the burning wells in Kuwait to production. Advantageously, a crane is used to install the separator at a safe distance from the well. The gas from the well is burned off at the site, and the oil is immediately pumped into Kuwait's oil gathering system. Diverters inside the separator prevent the oil jet coming out of the well from reaching the top vents where the gas is burned. The oil falls back down, and is pumped from an annular oil catcher at the bottom of the separator, or from the concrete cellar surrounding the well.

  • Patent number: 5192344
    Abstract: A vacuum cleaner having a substantially cylindrical tank with a bottom, a cover which pneumatically closes the tank to define a vacuum chamber, an eccentric inlet and an outlet through the tank cover which define a pneumatic path through the chamber and a vacuum source for causing air flow along the path from a dry to a wet filter vacuum cleaner. A convex baffle, in the shape of an inverted shallow bowl with a rim of diameter somewhat less than the diameter of the tank is adapted to be approximately concentrically mounted in the tank above its bottom and has an eccentric aperture which is vertically aligned with the inlet when the baffle is properly situated in the tank. A tube is adapted at its upper end to be connected to the inlet and extend downwardly, snugly through the aperture. The lower face of the tube is cut at an angle other than 90.degree. and optimally at approximately 45.degree..
