| 20090275234 | Shielded oilfield electric connector - A high-power, shielded, single-pole electrical connector and method for installing such a connector are disclosed. The connector has a single-pole connector housed within an electrically conductive outer shell. The inner, single-pole connector is electrically insulated from the outer shell. A shielding trap is used to provide electrical contact between the outer shell of the connector and a shielding layer of a shielded electrical supply cable. The inner, single-pole connector may be a male-female type or a lug-type. If a lug-type single-pole connector is used, a dual-shell, cylindrical insulator may be used to provide access to the lug bolts. Such an insulator may be realigned after the lug-bolt access is no longer required so that a complete insulating barrier is provided around the lug-type connector. A variable-angle, lug-type connector may be used. | 11-05-2009 |

| 20120014779 | DISC PUMP - A pump is disclosed having one or more rotating discs within a housing. The discs have a plurality of relatively small surface perturbations covering at least half of one side of their surface. The perturbations may be recessed or raised. In operation, a boundary layer is formed near the surface of the rotating discs. The fluid within the pump flows in a circular and outward direction, thus moving fluid from a central coaxial inlet to an outlet located at the peripheral wall of the housing. The surface perturbations produce turbulence within the boundary layer during operation. The pump is suitable for pumping liquids with entrained gases, liquids with entrained solids, liquids with both gases and solids, and thick liquids. | 01-19-2012 |
| 20120129242 | Falling Film Evaporator - An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed. An open lower end allows for injection of a heated material, which may be used to heat the solid surface. This process may be used to heat the fluid flow surface so that evaporation of the flowing fluid results. A falling film evaporator is one application of the disclosed invention. A carbon capture system using a thin, flowing algae film is another application. Other potential uses of the invention are disclosed as well. | 05-24-2012 |
