Title: Method of modifying near-wall temperature in a gas phase polymerization reactor
Inventor: SPRIGGS THOMAS EDWARD
IPC: C08F2/34
Filed: 1999-12-30
Abstract: A falling film of water is applied around the periphery of a fluid bed olefin polymerization reactor to cool the wall and reduce the temperature in the fluid bed near the inside surface of the wall.      Cooling has the effect of reducing static in the reactor, which in turn ameliorates a sheeting problem and can enhance production by facilitating control of the relation of the reactor temperature and the dew point of recycled gas. The process may be used concurrently with a gas cooling and condensing recycle system wherein at least some of the condensed recycle gas is injected in the vicinity of the internal wall surface.

Title: Pop-up handle assembly
Inventor: HALVORSON EDWARD M
IPC: E05B65/20
Filed: 2000-01-26
Abstract: A pop-up handle assembly includes a planar mounting panel which may be integral with a housing. The assembly also includes dual longitudinal bores generally parallel to one another and offset from each other. A handle that rotationally drives an interconnected shaft is carried by one of the bores to operate between locked and open positions. When in locked position, the handle is prevented from being rotated. When in open position, the handle extends outwardly from the housing and can rotate approximately 90 degree, to thereby drivingly rotate the shaft, which allows access to an enclosed space. A lock cylinder is carried by the other bore and rotates therein between locked and unlocked positions. When in locked position, the cylinder is not depressible. When in the unlocked position, the cylinder functions as a depressible push button which engages a retainer member to release the handle from locked position.

Inventor: KORTE JORN
IPC: B60K15/00
Filed: 2000-02-16
Abstract: For determining the adequate perviousneas of venting tube nipples (4) on fuel tanks (3) made of plastics material a test duct (12) is connected to the nipple (4) and air drawn into the test duct (12) from the tank (3). From measuring the partial vacuum of e.g. approx. 5 mbar or the volume flow rate in the test ducts (12) it can be determined whether the nipple (4) and its joint (9) to the tank (3) are sufficiently permeable. This test is very precise and silent and needs only little consumption of compressed air. Thereby the load on the sealing seat (14) between the test duct (12) and nipple (4) is only slight.

Abstract: A dynamic control valve system (10) adapted for inflatable restraint systems for vehicles. The system includes a control valve (12) having an inlet (18) in fluid communication with an inlet (22) in an airbag (24). The control valve includes a valve member (32) actuatable between a flow preventing position and a flow permissive position. High pressure fluid is supplied through the control valve (20) and on to the airbag (24).

Abstract: The present invention is a device to place an incision into matter (32) with a harmonious plasma cloud. A radio frequency generator system (10) produces electromagnetic waveform which is transmitted by an active transmitter incising electrode tip (28). This electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization, and a photoelectric effect which then triggers an avalanche effect for charged atomic particles at the surface of the active transmitter incising electrode tip (28). This electromagnetic wave is impedance matched, frequency matched, power matched, tuned to the plasma cloud in order to sustain, control a harmonious plasma cloud which demonstrates reduced atomic particle turbulence, and chaos while forming a coating over the surface of the active transmitter incising electrode tip (28). The magnetic bottle effect, the pinch effect, and the tunnelling effect are employed to trap, contain, compress, contour, focus, and amplify the energy of the incising plasma cloud.
