Abstract: A pallet post, which is adapted to be positioned between a plastic upper deck and a plastic lower deck of a pallet, is disclosed. The pallet post has a longitudinal axis, means for rotatably mounting the pallet post about the axis between the upper deck and the lower deck of a pallet, and at least three winglike arms which project radially from the axis. The winglike arms are substantially equally spaced about the axis and extend the length of the pallet post. The pallet post has the advantage that if struck by a tine of a fork lift truck, the post tends to rotate and to deflect the tine so that it passes the post without damaging the post or the plastic decks of the pallet between which the post is rotatably mounted.

Abstract: Laminates of glazing material and polyvinyl butyral plasticized with propylene oxide oligomers.

Abstract: The uniformity of bulked continuous filament yarns is improved by stabilizing the yarn path on draw pins and on heated draw rolls in a coupled spin-draw-bulk process wherein just before the yarn contacts a draw pin it is passed between two parallel guide pins in tandem in a zig-zag path which cause the plane of the yarn ribbon to rotate about the yarn axis by an angle of from 50.degree. to 90.degree. and back before contacting a draw pin. More uniform spreading of the yarn filaments on the heated rolls saves energy by permitting the use of lower roll temperatures.

Abstract: Preparation of isobutyric acid and esters by carbonylation of propylene in the presence of water or an alcohol, a palladium catalyst and ortho-substituted triarylphosphine.

Abstract: A process of forming an image of toner on a latent magnetic image in a magnetic imaging member followed by transfer to a heated transfer member. The transfer member is formed of a backing sheet coated with polyvinyl alcohol. The toner image is then transferred to a substrate using heat and pressure. The backing sheet portion of the transfer member is then stripped away and the polyvinyl alcohol is washed away with water. The surface portion of the substrate not protected by the transferred resist toner image is then permanently modified by etching or plating. Chemically milled shapes are prepared as well as printed circuits and printing plates. The printed circuits may be formed by (1) etching away areas of a metal surface not protected by the resist, (2) electroless plating on areas not protected by the resist or (3) electroplating areas of a metal surface not protected by the resist, removing the resist, and in the case of (2) and (3), etching away the metal previously covered by the resist.

Abstract: The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy compound, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.3. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.

Abstract: Polyvinylbutyral sheeting, plasticized with a hydrolyzable ester, having low acid concentration through the use of formic acid salt as an adhesion control agent.

Abstract: Pyrazolo [3,4-d] pyrimidine, and derivatives thereof, can be added to either a silver halide emulsion, or to a hydroquinone (litho) developer to accelerate development and reduce the induction period.

Abstract: Process for preparation of multicolor images on a single negative-working photosensitive layer which comprises imagewise exposing the layer through a transparency to form tacky image areas; toning the tacky image areas with a toner which becomes swollen or solubilized upon contact with the tacky areas; buffing or rubbing the toned image areas until glossy; and repeating the exposing, toning and buffing or rubbing using a different image-bearing transparency and appropriate toner. The process is useful in preparing multicolor proofs, e.g., maps, textile and wall covering design proofs and samples, etc.

Abstract: A breathable fabric which comprises a structure woven from thermoplastic polymeric tapes, wherein the woven structure is coated with a foamed permeable coating. The tapes are preferably made from polyethylene having a density between 0.940 and 0.970 g/cm.sup.3. The coating is preferably a lace coating made from polyethylene having a density between 0.910 and 0.940 g/cm.sup.3. The fabric is useful for making breathable sacks.

Abstract: A method and apparatus of electrophotography wherein before exposure of a photosensitive element to a light image the element is subjected to a substantially uniform light irradiation to release a part of the charge carriers trapped in a photoconductive layer of the element, thereby controlling the potential of a latent image to be formed on the element within a range fit for the development of the latent image.

Abstract: An improved thermoplastic pipe stub end for welding to thermoplastic pipe is disclosed. The stub end has a flange portion integrally joined to a neck portion which has inner and outer surfaces and terminates at a welding face. The improvement resides in the reduction of the length of neck portion such that it extends from the flange a distance in millimeters of not greater than 1.5 .sqroot.O.D., where O.D. is the outer diameter in centimeters of the neck portion at the welding face. The improved stub end permits higher strength heat welds to be made by butt fusion between the thermoplastic stub end and a thermoplastic pipe to be joined thereto.

Abstract: A window assembly comprises a hollow frame with a trackway mounted upon each frame side including opposed pairs of inner and outer channel tracks of dovetail shape in cross section. Opposed pairs of channel slides of dovetail shape are movably mounted in opposed tracks. A window support bracket overlies each slide and adjacent its lower end is pivotally mounted thereon. Upper and lower sashes are interposed between pairs of opposed support brackets and secured thereto. The upper and lower sashes and connected channel slides are adapted for vertical adjustments along the inner and outer tracks respectively, and the upper and lower sashes and connected support brackets are adapted for selective inward pivotal movement approximately 90.degree. to facilitate cleaning.

Abstract: The quality of a resin-bonded twisted string comprised of three flattened monofilaments in a side-by-side relationship is improved when the monofilaments are precoated with resin prior to twisting and then twisted in a zone wherein the excess lengths of the two outer monofilaments in the twisted configuration is compensated for during twisting by forwarding the two outer monofilaments at a positively controlled speed and allowing the speed of the middle monofilament to be controlled by being drawn into the twisting zone through a roller slot guide at a speed freely determined relative to the speed of the two other monofilaments entering the twisting zone.
