Abstract: A process for forming ionomer resins neutralized with aluminum is disclosed. In the process a copolymer containing carboxylic acid groups is melt blended in the absence of water with an aluminum compound of the formula ##STR1## where m is 0-2, n is 1-3 and the mixture treated with a volatile organic acid such as glacial acetic acid to activate the reaction between the acid groups of the copolymer and the aluminum compound. The organic acid is then removed from the copolymer by vaporization. Optionally, a moisture scavenger such as acetic anhydride is used to remove water which is incidentally present or formed by the reaction of the aluminum compound.

Abstract: A broadband signal broadcasting system comprising a circuit to encode video and audio signals forming a TV channel to be sent to a switching matrix, which is remotely operated by the subscriber; a circuit to multiplex two or more TV channel to be simultaneously transmitted on the subscriber's line, which can be a coaxial cable, a radio link or an optical fiber; and a circuit to receive the signals transmitted on the line, to separate two or more TV channels and to carry out channel decoding by supplying the subscriber's terminals with the corresponding video and audio signals. The system requires a single encoding and a single decoding of the nB.fwdarw.(n+m)B type on broadband signals, respectively at the output from signal sources and at the input of subscriber's terminals.

Abstract: Polymers containing by weight (i) from about 50 to about 85 parts of units derived from at least one monomer (FM) having the formula ##STR1## wherein R.sub.f is straight or branched-chain perfluoroalkyl containing 4-20 carbons;R is H or CH.sub.3 ; andn is an integer from 1-15;and (ii) from about 50 to about 15 parts of units derived from 3-chloro-2-hydroxypropyl methacrylate and/or acrylate (CHPM/A) or their bromo analogs. Preferably, the polymers contain by weight between 65 and 75 parts of units derived from FM and 35-25 parts of units derived form CHPM/A, particularly a copolymer consisting essentially by weight of 75 percent of a mixture of FM and 25 percent of CHPM. Polymers impart superior oil- and water-repellency and anti-soiling characteristics to fibrous substrates, and may be applied as a spin finish, particularly to nylon filaments.

Abstract: A connector for interconnecting a multiconductor cable and a printed circuit board. The connector includes means for receiving and contacting individual conductors at one end of the conductor housing. It also includes at the other end means for plugging the connector onto a printed circuit board so that electrical contact is made between the conductors of the cable and contact strips on the printed circuit board.

Abstract: This invention relates to the use of ethylene/tetrafluoroethylene (ETFE) or ethylene/chlorotrifluoroethylene (ECTFE) polymers to produce a foamed coating of insulation over wire and used as wire pairs for transmitting electronic signals, in which the foamed coating is surrounded by a protective jacket or skin made of one of the two polymers.

Abstract: A robotized apparatus for forming a web to be used as a reinforcement in a plastic composite. The apparatus has a dispensing head including a freely rotatable tube which is moved according to a desired pattern. The tube terminates in a horn from which a continuous strand is delivered into a bed of pins.

Abstract: This invention relates to a composition and method of temporarily reducing the permeability of subterranean formations penetrated by a wellbore. In particular, it relates to an inexpensive, low molecular weight condensation product of hydroxy acetic acid with itself or compounds containing other hydroxy-, carboxylic-acid-, or hydroxycarboxylic-acid moieties and method for preventing fluid loss during well treatment.

Abstract: A pierce contact element for a connector with a housing in which the end of a cable with one or more insulated conductors is inserted. The pierce contact has a pointed part intended to pierce into an insulated conductor and a contact crown intended to make contact with the contact strip or contact wire of a matching connector housing. The contact crown is shaped so that its radius of curvature is larger than half the width of the contact crown in order to reduce wear on the surface contacting the strip or wire of the matching connector. In one embodiment, pierce contact is designed so that its pointed part pierces in the longitudinal direction into the end face of the conductor.

Abstract: Azeotropic mixtures of 1,1,2-trichloro-1,2,2-trifluoroethane (FC-113) and 1,2-dichloro-1,1-difluoroethane (FC-132b) with methanol or ethanol, the azeotropic mixtures being useful in solvent cleaning applications.

Abstract: Pyrazole sulfonamides are found to have utility as preemergent and/or postemergent herbicides or plant growth regulants.

Abstract: A self-locking chuck which can clamp the hollow core of a bobbin to a rotor has two nuts which mate with externally threaded sections of the rotor and have threads inclined in opposite directions or threads of different pitch so that they move axially toward or away from each other in response to joint rotation relative to the rotor or vice versa. The nuts are surrounded by two or more axially parallel torque transmitting segments whose external surfaces are movable into torque-transmitting engagement with the internal surface of a core in response to joint rotation of the nuts relative to the rotor. To this end, the inner sides of the segments are provided with a first set of cam faces and the outer sides of the nuts are provided with a second set of cam faces which cooperate with the cam faces of the segments to move the segments radially outwardly in response to joint rotation of the nuts relative to the rotor.

Abstract: Photopolymerizable composition comprising monomer, photoinitiator and triarylmethane or xanthene dye exhibit increased photospeed with an exposure to light above 400 nm with an intensity of at least 1500 lumen/sq. meter for one hour or more, with a preferred exposure of 15,000 lumen/sq. meter for 10 seconds or longer. A photospeed layer protected from exposure to oxygen has been shown to continue to maintain increased photospeed.

Abstract: A vinyl covered fiberglass shell preformed to fit the roof of an automobile. The vinyl covered fiberglass shell simulates the appearance of a padded vinyl fiberglass roof cover without the use of padding. The fiberglass shell includes a series of recesses which are molded into the outer surface of the shell when the shell is first formed. The vinyl covering is then placed over the entire outer surface of the fiberglass shell including the recessed portions. Decorative pieces such as molding strips, decorative letters, and an emblem are placed over the vinyl covering in the location of the recesses.
