Abstract: A coating composition comprising a dispersion of an epoxy resin, a nitrogen resin crosslinker such as a melamine formaldehyde, a particulate fluorocarbon such as PTFE, and citric acid can be applied to substrates such as polysulfones and cured at low temperatures on the order of 107.degree. C. The resulting coating is especially useful as a barrier to seal the surface of the substrate and to improve abrasion resistance.

Abstract: A process and apparatus for continuously forming a reinforced membrane of fluorinated polymers containing sulfonyl and/or carboxyl groups in melt-fabricable form and, after hydrolysis, the corresponding membrane in ion exchange form. The membrane thus formed has exceptional uniformity, and this membrane so made, when used as the membrane which separates the compartments of a chloralkali cell, offers the advantages of low operating voltage, low power consumption and high current efficiency, and a long useful life without rupture.

Abstract: The invention relates to a process for the preparation of alkanediols by the electrochemical coupling of a halohydrin in a divided electrolytic cell having a copper cathode, in an aqueous system whose catholyte contains copper ions and a ligand.

Abstract: Process for packing of tow utilizes a movable container with self contained strapping guides as a baling chamber. The filled container is moved into position under a ram to compress the product to a set height. After compression one side of the container is opened permitting an automatic strapper to strap the bale and after strapping the bale is ejected from the container which returns to a filling station and the cycle is repeated.

Abstract: A felt-like layered composite of the following structure:a. a first layer of a predominantly horizontal coplanar superimposed layers of filamentary polytetrafluoroethylene components interrupted by occasional interlayered orientation;b. a thin high density nonwoven layer of fine glass staple fibers;c. a scrim fabric of polytetrafluoroethylene fibers andd. a second predominantly horizontal coplanar superimposed layers of filamentary polytetrafluoroethylene components interrupted by occasional interlayer orientation;wherein the layers are mechanically bonded together by filamentary polytetrafluoroethylene components extending vertically throughout the composite and a process for making this composite; the composite is useful as a filter fabric and is primarily used for bag filters to remove fly ash from the gaseous combustion products of coal fired furnaces and boilers.

Abstract: A dressing device for securing on a body portion of a patient an infusion needle or catheter and a safety loop of the tubing associated therewith. The dressing device comprises a base strip of flexible material having an adhesive coating on its underside for attachment to the patient's skin and a gauze pad extending transversely of its central portion for direct contact with the puncture site. The base strip has a central longitudinal slit formed therein extending from an end edge of the base strip approximately to the middle thereof and terminating in a flap forming portion. That portion of the slit overlying the gauze pad, including the flap forming portion, extends through the gauze pad as well. The slit enables placement of the dressing device about the infusion needle or catheter with the flap forming portion located at the puncture site. A flexible cover strip has a first portion affixed to the upper surface of the base strip and a second portion covering the slit in the base strip.

Abstract: A brassiere which has a pair of cups, opposed side portions extending laterally from these cups and a pair of back portions extending from the side portions also has along lower regions of the cups, side portions and back portions and elongated continuous stretch band which is in a stretched condition extending around the body of the wearer, when the brassiere is worn. This stretch band serves to anchor the brassiere to the body of the wearer so as to oppose undesirable displacement of the brassiere during wearing thereof.

Abstract: Pump means comprising a pump and a motor, combined to constitute a pump unit for submersion in a liquid, and a pump delivery pipe and a vertical guide track both fixedly mounted in a liquid container, such as a sewage weill for instance, the latter guiding the pump unit and enabling it to be lowered into the liquid tank so that the delivery port of the pump will connect with the delivery pipe, and the pump unit having been fitted with a bipartite slide carried on the guide track. The guide track comprises two guides and that the slide comprises two lower projections and two upper projections, and that the slide has been so connected to the delivery aperture of the pump that the lower projections are located below and the upper projections above the delivery port.

Abstract: A pressure-tight, rotary pipe coupling joins rotating, high temperature fluid transmission lines. Pressure seals of the coupling are maintained at a temperature lower than that of the high temperature or primary transmitted fluid by thermally insulating the seals from the high temperature fluid and by pumping a fluid coolant through annular cavities located adjacent the seals. A balanced pressure structure substantially eliminates thrust forces between the coupling members and reduces rotating friction.

Abstract: An inflatable core for use in forming a thermal break in a metal frame for a door and/or window by moulding and curing thermal barrier material, such as resin, in two parallel, laterally spaced, elongate gaps defined between respective pairs of confronting elongate surfaces of the inner and outer frame elements which when assembled form a box-section member. The gaps are converted into respective mould cavities for the resin by the pressure of shoes against the elements adjacent the respective gaps to close one side thereof, the shoes being removed only after the resin has cured to leave the finished thermal break. The shoes are carried on opposite walls of a laterally expansible tube which is inserted into the box-section and is expanded to press "non-stick" surfaces of the shoes against the respective gaps ready for the moulding and curing of resin therein, while maintaining the gap dimensions.
