The mole-to-mole ratio of diethylaluminum alkoxide to aluminum alkyl ranges from 0.05 to 0.2. This invention is effective for the aluminum/transition metal ratio for the polymerization of olefins ranges from about 100 to about 500. Polymerization yield increases of greater than 10% are realized. The diethylaluminum alkoxide is preferably diethylaluminum ethoxide.

Title: Programmed level gate driver for switching power supply
Inventor: KAYSER KENNETH W
IPC: H02M1/08
Filed: 1991-07-12
Granted: 2000-06-15
Abstract: A programmable gate drive for a switching power supply incorporating first and second transistors connected in series between a positive voltage source and a reference voltage, means for connecting a point intermediate the first and second transistors to a gate of a power FET for serving to regulate the voltage supplied at an output of the switching power supply, and means for driving bases of each of the first and second transistors with signals so as to turn on and turn off the power FET at predetermined times during plural cycles of operation. <IMAGE>

Title: Racking storage system
Inventor: BETTELEY COLIN ERIC
IPC: A47B96/14
Filed: 1992-03-18
Granted: 1999-09-01
Abstract: PCT No. PCT/GB92/00483 Sec. 371 Date Mar. 24, 1994 Sec. 102(e) Date Mar. 24, 1994 PCT Filed Mar. 18, 1992 PCT Pub. No. WO92/16126 PCT Pub. Date Oct. 1, 1992A post for racking comprises a front wall (2), and first and second side walls extending rearwardly from each longitudinal side of the front wall, the front wall having a longitudinally extending trough (7), and a first and a second series (5, 5') of spaced apertures (15) on opposite sides of the trough (7). Each side wall comprises a front wall portion (3, 3'), and a second side wall portion (4, 4'), with the two portions joined by an inwardly inclined portion (11, 11', 13 13'). The post is interchangeable with a number of posts having different load bearing capabilities. This is achieved by ensuring that the distant b separating outer faces (25) of the trough (7) from the outer faces (26) of the adjacent side walls are the same for all posts in the range.
