Title: Cyclic poly(arylether) oligomers, a process for preparation thereof, and polymerization of cyclic poly(aryl ether) oligomers
Inventor: MULLINS MICHAEL J
IPC: C08G73/18
Filed: 1990-08-13
Abstract: ABSTRACT         The present invention is directed to cyclic poly(aryl ether) oligomers and mixtures thereof, and methods for the preparation thereof in a highly dilute reaction medium under reaction conditions favorable for ring closure at low degrees of polymerization.  These oligomers are represented by the general formula   where each Y is divalent oxygen or divalent sulfur, each Ar is an aromatic diradical which comprises one or more C6 to C20 arylene groups and has at least one electron withdrawing group attached to an aromatic ring, and n is an integer from 1 to 20 with the proviso that for integer values of n equal to 1 or 2 all linkages between independent aromatic rings comprise at least one atom.       The present invention includes a process for the preparation of poly(aryl ethers) from cyclic poly(aryl ether) oligomers.  These low melt viscosity cyclic oligomers undergo ring opening and chain extension upon heating in the presence of a catalyst, 37,163B-F     forming high molecular weight linear polymers with no coproduct formation.  Finished thermoplastic parts and composites may be prepared using this technology with processing techniques normally restricted to thermosetting monomers.     37,163B-F

Abstract: A fitting connection for joining plastic tubing to associated structure comprises a main fitting body having an axially inwardly extending cylindrical chamber with an inner end portion of a diameter d1 terminating at its innermost end in a radially inward extending wall.  The outer end of the chamber opens to the exterior of the body and has an open diameter d2 which is larger than d1 with a shoulder at the juncture between the inner and outer end portions of the chamber.  Plastic tubing having a circumferential corrugation adjacent an end portion thereof extends axially into the chamber with the innermost end of the tubing abutting the wall.  A retaining ring acts to retain the tubing in the fitting body and includes a sleeve received in the outer portion of the chamber with the innermost end of the sleeve in engagement with the shoulder and a plurality of resilient tabs having free ends extending toward the shoulder. Radially inward extending first detents are carried on the tabs adjacent their free ends at a location to enter into the circumferential corrugation on the tubing and radially outward extending second detents are carried on the exterior of the tabs to extend into radially open slots formed in the fitting body adjacent the shoulder for preventing axial withdrawal of the retaining ring and the tubing.

Title: Electrochemical and surface chemical methods for prevention of the atmospheric oxidation of sulphide tailings and of resultant acid generation
Inventor: AHMED SYED
IPC: C23F13/02
Filed: 1990-12-10
Abstract: Abstract of the Disclosure Novel means are provided to prevent atmospheric oxidation of sulphide tailings with resultant acid generation,  that  is  generally  considered  to  be responsible for acid mine drainage.  The means include electrochemical protection for preventing atmospheric oxidation of sulphide tailings.  Such electrochemical protection includes anode and cathode compartments separated by a suitable diaphragm, and filled with an electrolyte solution.  A bed of sulphide tailings to be  protected  and  a  graphite  cloth  as  a  feeder electrode and used as a cathode are provided in the cathode compartment.  A graphite rod used as an anode is provided in the anode compartment.   A standard reference  electrode,   e.g.   a  saturated  calomel electrode,  is disposed in the electrolyte solution adjacent  to  the bed  of  tailings  in  the  cathode compartment.   A constant power source interconnects the anode  and  the  cathode,  e.g.  a  potentiostat connected to the anode, to the cathode and to the reference electrode.  Several configurations of this arrangement are possible,  including a large scale version.    Means  are  also  provided  by  similar arrangements for growing a protective oxide film on sulphide tailings, and also to provide an adherent, stable, inert, coating of asphalt on sulphide tailings to prevent atmospheric oxidation and hence acid mine drainage.

Abstract: VOLLEYBALL NET ADJUSTER IV     Abstract: A device for quick, easy set-up and adjustment of volleyball nets, comprises pulleys which tighten both the upper and lower net cables in unison via a pulley rope. The tension of the rope is multiplied by the pulleys, reducing or eliminating the need for winch means, other than a rope lock or cleat. The pulleys may be attached to a vertical slide, for infinite height changes without net detachment. An Ideal tension ratio, selected by the designer, is maintained between the upper and lower net cables, to eliminate vertical net slack, for consistent ball rebound off the net and protection of poles. The net cables are pulled in the same direction, keeping the net ends and antennas, if any, vertical. This allows the net fabric to be tensioned horizontally along with the cables, without separate cords from the net ends to the poles. These features provide convenience and speed for setting up nets, changing between men's and women's net heights, and compensating for the changing level of sand courts.

Title: Heavy oil catalytic cracking process and apparatus
Inventor: OWEN HARTLEY
IPC: B01J23/40
Filed: 1991-12-20
Abstract: HEAVY OIL CATALYTIC CRACKING PROCESS AND APPARATUS              ABSTRACT      A process and apparatus for fluidized catalytic cracking of heavy oils is disclosed using a modified high efficiency catalyst regenerator.  A fast fluidized bed coke combustor, which is essentially free of gas/catalyst separation means, partially regenerates catalyst and discharges a steam laden flue gas and catalyst into a dilute phase transport riser.  Closed cyclones separate catalyst from steam laden flue gas exiting the transport riser outlet.  This flue gas is isolated from a second fluidized bed of catalyst maintained in a vessel containing the transport riser and closed cyclones.  Coke combustion in the drier region of the second fluidized bed is possible. Catalyst deactivates less in the second fluidized bed because it is drier.
