Patent number: 5207810Abstract: 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.Type: GrantFiled: May 6, 1992Date of Patent: May 4, 1993Assignee: Baker Hughes IncorporatedInventor: Ketankumar K.

Patent number: 5207808Abstract: 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.Type: GrantFiled: August 5, 1992Date of Patent: May 4, 1993Assignee: Aisan Kogyo Kabushiki KaishaInventors: Kazumi Haruta, Hideo Yamada, Kenji Koeda

Patent number: 5191940Abstract: 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.Type: GrantFiled: August 22, 1991Date of Patent: March 9, 1993Assignee: The United States of America as represented by the United States Department of EnergyInventors: Carol T.
