Abstract: A process for soldering a substrate surface which allows low ionic contamination without a cleaning operation which comprises (a) applying a stannous fluoride or eutectic mixture thereof to the substrate surface and (b) applying solder to the flux applied in (a). The stannous fluoride which is relatively inactive below its melting temperature can be applied to the substrate surface and the so treated substrate held for an extended period of time prior to soldering without any harmful effect on the substrate. The process is useful in electronic assembly that would include attachment of components to circuit boards, tinning of circuit boards, pretinning of component leads, connectors etc.

Abstract: A garment hanger adapted to support an elongated rod. The hanger includes an elongated body having two ends and a hook portion therebetween. The ends of the body extend downwardly to form a pair of spaced legs each having a rod receiving portion, with each rod receiving portion being defined by a bottom wall, a back wall joined to the bottom wall and forming part of the body and an upstanding resilient tongue joined to the bottom wall and spaced a predetermined distance from the back wall to define a rod receiving slot. The back wall includes an opening therein in alignment with the tongue defined by the bottom wall, top wall and opposing side walls, the surfaces of the side walls facing the tongue each having an undercut for capturing the rod when inserted in the slot. The tongue biases the rod in the slot against the undercuts to lock the rod in the rod receiving portions.

Abstract: The invention provides novel polyesters, fibers and films, nonwovens from the fibers and disposable products of the polyesters such as diapers from the nonwovens. The products are degradable under the conditions typically existing in waste composting processes, have low ingredient costs and yet provide strength and toughness properties adequate for end uses such as in disposable diapers. The polyesters are based upon polyethylene terephthalate copolymerized with diethylene glycol and a 5-sulfoisophthalic acid.

Abstract: Disclosed is a non surgical method of modulating spinal curvature in developing vertebrates. Agents capable of temporarily interfering with neuromuscular transmission, e.g., botulinum toxin, are injected into the musculature of the back to create an imbalance in the muscular support of the developing spine. The procedure may be used to produced non human scoliosis animal models and in the clinical management of juvenile scoliosis.

Abstract: Process for the preparation of toner particles for electrostatic liquid developers comprising(A) dispersing at ambient temperature colorant, A-B diblock polymer grinding aid as described, and a carrier liquid;(B) adding to the dispersion a thermoplastic resin and dispersing at an elevated temperature to plasticize and liquify the resin;(C) cooling the dispersion as described while grinding with particulate media,(D) separating the dispersion of toner particles average by area particle size less than 10 .mu.m, from the particulate media, and(E) adding during or subsequent to step (B) at least one ionic or zwitterionic charge director compound.Steps (A) and (B) can be combined by adding the thermoplastic resin to the other ingredients and dispersing at an elevated temperature. The liquid developer can be prepared omore quickly by the process than by other known processes. The liquid developers are useful in copying, in making color proofs, etc.

Abstract: The method and means for carrying out pre-press color proofing processes for color press printing, wherein at least one photosensitive film is laminated onto a sample of the paper intended to be used for the final press printing, which sample has been removably applied to a shape-stable and dimensionally stable support, exposed to light, and colored with a dry toner, characterized in that an interlayer which can be stripped from the support without damage has been applied in advance on the reverse side of the paper intended to be used for the final press printing.

Abstract: A process for preparing a narrow molecular weight distribution poly(tetramethylene ether) glycol (PTMEG) from a PTMEG starting material via liquid-liquid extraction which employs methanol, water and non-polar solvent wherein the amount of non-polar solvent is, by weight, less than the PTMEG starting material.

Abstract: An integral three dimensional object is formed from a photohardenable liquid composition containing radiation deflecting matter which is a thermal insulator and having a different index of refraction from the liquid.

Abstract: A melt-processable thermoplastic composition consisting essentially of a blend of a melt processable thermoplastic fluorocarbon polymer and about 0.05 to about 0.5 percent by weight of an elastomeric copolymer of tetrafluoroethylene and a perfluoro(alkyl vinyl ether) exhibits improved processing properties.

Abstract: Disclosed are rigid fluorinated monomers, their preparation, and polymers derived therefrom based on two novel tricyclic xanthene core systems, 9,9-bis(perfluoroalkyl)xanthene (I) and 9-phenyl-9-perfluoroalkylxanthene (II). The monomers have utility in the preparation of advanced high-performance polymers, particularly polyimides.

Abstract: Electronics and a playing method stimulate abstract spatil-relations ability, particularly memory of abstract space, in youngsters--without requiring them to know or spell game commands, or to find keys on a typewriter-like keyboard. The game exploits the competitive instinct by rewarding ability to recall complex geometric abstractions, while yet encouraging play by those who lack that ability. Dedicated manual inputs are used by each player to enter moves--in the pure form of directions in which the player wishes to go. An audio speaker signals which player's move it is, and whether each attempted move is valid. A digital microprocessor is used to define a maze and each player's position in it, and to receive moves from the directional inputs, and to operate the speaker in reply to attempted moves. The processor has no functional connection with any device for displaying a direct pictorial representation of any part of the maze, and indeed no such direct picture is electronically developed or shown.

The lower accelerating rollers and the upper accelerating rollers advancing the workpiece rolls further along the path of the first squeezer conveyor. At least one upper accelerating roller having a drive for driving it at a higher speed than the other accelerating rollers. A second conveyor being provided for receiving the workpiece rolls. The receiving end of the second conveyor either being at or below the level of the lower accelerating roller. When the receiving end of the second conveyor is below the level of the lower accelerating rollers the workpieces are rotated 90 degrees away from their original endwise advance by the action of the upper accelerating roller that has a drive for driving it at a higher speed than the other accelerating rollers.
