Abstract: Vises utilizing a threaded screw and nut to translate rotary motion of the screw into linear relative movement of vise components. The nut may be a half-nut urged into contact with the screw by a cam that may be operated by a lever located near the handle for turning the screw. A tail vise embodiment may be mounted to the underside of a workbench without signification bench modification and positions the screw near the front edge of the bench top.

Abstract: An impeller having a rotation axis, a radial direction, a backplate and a number of vanes which are connected to the backplate at a line of connection is provided. Each vane has an upstream side, a downstream side and an outer side. The downstream side of each vane has an edge portion which is located near the outer side. The vanes project radially over the backplate and the downstream side further includes a connecting portion connecting the edge portion to the backplate and including an angle with the radial direction. The connecting portion includes a convex rounded portion which is located near the line of connection. Moreover, a turbocharger having an inventive impeller is disclosed.

Abstract: A gas turbine arrangement comprising: a passage, annular in cross section, for conveying combustion gases; located in the passage, turbine blading to be driven by the combustion gases; a diffuser, annular in form, for diffusing the combustion gases following their passage through the turbine blading; and a collector for collecting the combustion gases diffused by the diffuser, the collector comprising an annular main part, and, located at a position around the annular main part, a neck exit, in use of the gas turbine arrangement, combustion gases collected by the collector being conveyed around the annular main part of the collector in opposite senses so as to arrive at the neck exit of the collector travelling in opposed directions, wherein the neck exit of the collector includes a partition device whereby the opposed direction flows at the neck exit are kept substantially separate.

Abstract: The present invention provides a system and method for generation of nitrogen enriched air for inerting aircraft fuels tanks. One embodiment of the present invention includes a duct assembly; a primary heat exchanger; a gas generating system heat exchanger; a first temperature sensor; a second temperature sensor; a controller monitor; a valve; an air separation module assembly having a primary module and a secondary module; at least one flow control orifice; and a pressure sensor. The present invention utilizes a minimal complement of components and streamlined processes, thus minimizing structural and operational costs while optimizing performance and safety features.

Abstract: An electronic drive system using a plurality of drive circuits for enabling greater plurality of functions by selectively placing drive signals on the driver outputs at one of two possible polarities. At least one of the enabled functions taking a substantially shorter time for enablement, thereby allowing at least two of the plurality of functions to share a common driver output enabling signal.
