Abstract: The hierarchical orgainzation of programmable logic arrays permits the control of microporcessor functions to be achieved in a way which allows otherwise wasted clock time to be used. The mostly independent operations of the several PLS's is organized by "handshake" signals from the latches of one PLA to those of another via AND circuits operative to selectively enable clock signals, in some instances, and data in other instances, to be applied to the latches. The use of the AND circuits enables requisite operations to be achieved with relatively small PLA's.

Abstract: The upper housing for rotatably supporting a driving scroll in a sealing container is provided with an annular chamber to be maintained at the atmospheric pressure.  The annular chamber is communicated with a compression chamber formed between the driving and driven scrolls through a discharge conduit which is formed in the driving shaft of the driving scroll.

Title: Method for varying the melting points and lolecular weights of polyolefins using metallocene catalyst systems
Inventor: EWEN JOHN A
IPC: C08F4/42
Filed: 1987-10-12
Granted: 1995-07-25
Abstract: The present invention provides a method for varying the melting points and molecular weights of polyolefins by changing the structure of the catalyst used in the polymerization. The catalysts that are useful in the present invention are chiral, stereorigid metallocene catalyst of the formula R''(C5R'm)2MeQ. The catalysts include a bridge structure between the (C5R'm) groups and may contain substituents on the groups. It has been discovered that the melting points and molecular weights of the polymers produced by such catalysts are influenced by the bridge and substituents added to the (C5R'm) groups. Thus, the present invention provides a method for varying the melting points of the polymer product and a method of varying the molecular weights of the product by changing the components and structure of the metallocene catalysts. The present invention also provides a process for polymerizing olefins in which the melting points and/or molecular weights of the product may be controlled. Also included in the invention is the discovery that the melting points of the products are controlled by the number of inversions in the xylene insoluble fraction of the polymer.

The partially-treated wastewater overflowing from the quiescent zone (14) is introduced into one or more contact zones (30) wherein it is agitated, preferably by aeration, in the presence of a powdered adsorbent, agitation is terminated and the solids are allowed to settle by gravity and, after completion of settling, clarified, substantially solids-free water is withdrawn from each contact zone.
