Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to the preparation of solution polymers and rubbers from vinyl monomers using a new catalyst complex of a barium di-tert-alkoxide-hydroxide salt and an organic lithium compound.  In particular, homopolymers and copolymers of butadiene with styrene and/or isoprene, pre-pared with this catalyst, are uniquely characterized by the butadiene units having a low vinyl content (not over about 12%) and a trans-1,4 structure of from about 70 to 81%.  Also, the copolymer has a random comonomer sequence distribution. This molecular structure permits elastomers containing little or no styrene to have sufficient stereoregularity to crystal-lize.  Furthermore, the butadiene homopolymer and copolymer with styrene and/or isoprene exhibit a broad molecular weight distribution as well as tack and green-strength which are valuable properties for a rubber to possess when building tires.

Abstract: ABSTRACT OF THE DISCLOSURE         Polyurethane resins of higher than desired molecular weight with or without gel fractions which comprise insoluble material due to crosslinking or excessive degree of polymer-ization are treated in the solid state with a liquid or gaseous pri-mary or secondary amina under thermal conditions which cause aminolysis of both linear linkages and crosslinkages. By this procedure, the average molecular weights of the products can be reduced to acceptable levels. Also, if the product contains gel fractions, these too can be reduced to negligible levels.         The procedure is applicable to both polyether and polyester urethanes and is effective to provide improved polymer character-istics for thermoplastic processing and solution applications.

Title: Crimped connector assembly for fiber optic  cables or the like
Inventor: MONAGHAN KEVIN J
IPC: G02B6/40
Filed: 1979-08-30
Granted: 1982-09-07
Abstract: ABSTRACT         The present invention relates generally to fiber optics and, more particularly, to a fiber optic connec-tor assembly for a fiber optic cable having one or more single optical fibers therein.  It is highly desirable to provide for crimping of fiber  optic cables for termination to contacts or connector assemblies as is commonly done with electrical cables.  However, if an optic cable is crimped like an electrical cable, the one or more single fibers in the cable will be over-stressed and damaged.  In a fiber optic cable, the crimping must be done to the strength members which surround the optical fibers.  According to the present invention, a connector body is provided for receiving the optical fibers of the cable and has a rear end portion over which the strength member of the cable is positionable  The rear end portion of the connector body is provided with one or more annular crimp receiving grooves.  A ferrule member is positionable over the grooved rear end portion of the connector body for crimping the strength member between the ferrule member and the connector body.  The ferrule member is crimped to have one or more crimping ribs which are nested in the grooves of the connector body clamping the strength member therebetween.  The included grooves of the connector body are smaller than the ribs of the ferrule member so as to increase the number of crimping areas between the connector body and the ferrule member.

Abstract: SYSTEM FOR RECLAIMING PLASTIC FROM      METAL PLATED PLASTIC SCRAP            ABSTRACT OF THE DISCLOSURE          Chrome plated plastic scrap is chopped into small pieces and then, while subjected to sub-zero temperatures, is centrifugally impacted thereby producing a mixture of particles of chrome and plastic.  Most of the chrome particles are removed by subjecting the mixture to a magnetic field.  The remaining, mostly plastic particles are classified to obtain usable, predominantly plastic particles within a predetermined size range, those particles exceeding this range being, if desired, recycled for subjection to said centrifugal impacting step.  The usable particles are thus reclaimed for reuse, after repelletizing, in extrusion or molding techniques.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved method for electrolyzing alkali metal halide.          Electrolysis is carried out by supplying an aqueous solution of a halide of alkali metal into an anode chamber partitioned by a cation-exchange membrane and water into a cathode chamber to obtain halogen from the anode chamber and hydrogen and alkali hydroxide from the cathode chamber.  The cation-exchange membrane is a fluorocarbon polymer membrane which is prepared by arranging one side thereof to have a cation exchange group concentration lower by 10 to 30% within a depth range of 1 to 100µ than that of the remainder of the membrane.  The anode chamber is prepared with this side of the membrane which has the lower cation exchange group concentration arranged to face the anode chamber.          By this arrangement, a high purity alkali hydroxide can be manu-factured at a high rate of decomposition of halide of alkali metal and at a high current efficiency.
