Abstract: Serial No. 215,483 E.I. du Pont de Nemours and Company (Hoeschele, Guenther K.) ABSTRACT OF THE DISCLOSURE           Segmented thermoplastic copolyester elastomers containing recurring polymeric long chain ester units derived from dimer acid and low molecular weight glycols and short chain ester units derived from dicarboxylic acids and low molecular weight glycols.  At least 70% of the dicarboxylic acid used is terephthalic acid and at least 70% of the low molecular weight glycol is 1,4-butanediol.  The short chain ester units constitute about 25-95% by weight of the polymer.  Such copolyesters rapidly harden from the molten state and have outstanding resistance toward heat aging and photodegradation.  Such copolyesters can be injection, compression, transfer and blow molded to form elastic molded articles e.g. tires and can be readily extruded to produce, for example, films, tubing and other forms having complicated cross sections.

Abstract: Abstract of the Disclosure Coated architectural glass system having a transparent substrate with a surface and a multi-layer coating disposed on the surface.  The multi-layer coating comprises first and second metal layers and a dielectric layer disposed between the first and second metal layers.          The first and second metal layers have a thickness ratio so that the transmission of the coating can be changed independent of its reflection properties, by varying the thickness of the metal layers while maintaining the ratio constant.  The dielectric has a thickness such that the reflection from the coating is not strongly colored in the region of 400 millimicrons to approximately 700 milli-microns.  In the method, the transmission of the coating can be changed merely by varying the thickness of the first and second metal layers in accordance with a thick-ness ratio.

Abstract: APPARATUS FOR CONTROLLING OPERATIONAL PARAMETERS    IN A POLYMERIZATION AND RELATED METHOD                 ABSTRACT OF THE DISCLOSURE         In apparatus for polymerizing high-pressure ethylene to produce polyethylene, a tubular reactor is connected to a source of high pressure ethylene.  A piston-type intensifier pump assem-bly supplies an initiator solution to the tubular reactor.  This solution includes one or more catalysts which promote the poly-merization reaction.  Within the tubular reactor, a peak tempera-ture occurs in downstream proximity of the point at which the ca-talysts are introduced.  If the catalysts are introduced at more than one point, a temperature peak will result downstream of each of such points.  For various reasons, these peaks can be displaced along the tubular reactor from time to time as the reaction pro-ceeds.  Therefore, a plurality of thermocouples are distributed at spaced positions in the tubular reactor throughout the local-ized zone in which each peak temperature might occur.  These ther-mocouples generate signals which are fed into a gating arrange-ment which selects the peak signal which is compared in a compar-ator circuit with a preset reference signal representative of the peak temperature which is desired.  A difference signal is gener-ated which relates to the difference between the peak temperature thermocouple signal and the reference signal with which it is com-pared.  This difference signal is converted by a transducer into a pressure signal which is fed to a control valve which controls the speed of operation of the intensifier pump feeding the initi-ator into the reactor just upstream of said localized zone.  If initiator is fed into the reactor at more than one point, a sepa-rate intensifier pump assembly operated by a separate set of con-trols will be provided for each point.     -i-

Abstract: ABSTRACT     This invention relates to an internal-combustion engine of generally spherical configuration having a generally spherical rotor mounted on a rotor shaft in a generally spherical shell.          Combustion chambers are formed in appropriate recesses in the rotor and the inside of the spherical shell.  The recesses are bounded by fixed partitions and movable pistons between the fixed partitions so that a series of combustion chambers are formed one on each side of each piston.  The pistons are each connected to a central hub at the center of the rotor, and the hub is rotatable to a limited extent in a direction perpendicular to the rotor shaft.  The pistons are therefore able to sweep through limited angular motion and during such motion increase the volume of one series of combustion chambers and decrease  the volume of the other series of combustion chambers.  A mechanical activating mechanism is provided so that the central hub is caused to rotate in a reciprocating manner through various angular positions that are predetermined in relation to the angular position of the rotor; in this manner the piston sweeping motion is precisely linked to the angular position of the rotor.  Appropriate ports and ignition components are provided so that fuel and air can enter the various combustion chambers in proper sequence, be compressed, burned and exhausted also in proper sequence.

Abstract: APPARATUS AND PROCESS FOR SURFACE TREATMENT      Abstract of the Disclosure An apparatus and process are provided for the safe, economic and pollution-free exposure of articles to reactive fluids to alter their surface characteristics.  The articles are exposed to one or more fluids which are transferred back and forth from a reaction chamber to a holding chamber.  As the fluids are transferred they pass through a trap designed to remove reaction-by-products without affecting valuable reactant  fluids.   Since the fluids can be transferred under vacuum and the overall reaction can take place at relatively low temperatures, the process provides a convenient and safe method for handling reactive fluids.  The process is particularly useful far the halogenation, for example fluorination, of a variety of articles, such as plastic containers, aerosol bottles and films to improve their barrier resistance to solvents and gases.

Abstract: STORM WINDOW CONSTRUCTION   ABSTRACT                A storm window construction includes longitudin-ally grooved framing strips attached to the four faces of a window casing either inside or outside the window glass. Edge portions of a clear flexible plastic membrane stretched across the window opening and spaced from the glass are held within the grooves of the framing strips by bead strips to maintain the membrane under tension and provide an insulat-ing air space between the membrane and the glass.  The bead strips are oblong and can be inserted in the framing strip grooves only along the short diameter of the bead.  Once in the groove the bead strip tends to rotate into wedging engagement with cylindrical inner wall portions of the groove under membrane tension to secure the bead and membrane in place.  Surface portions of each bead strip intersected by its short diameter and portions of each framing strip at the entrance to the groove may be scored or toothed long-tudinally to resist removal of the bead strip from the groove of the framing strip.  One form of framing strip is channel-shaped in cross section and has an opening in its web portion and a slidable plastic insert for covering such opening.  A second form of framing strip has two parallel grooves for receiving separate bead strips for securing two parallel spaced membranes to provide two insulating air layers between the window glass and the outermost membrane from the glass. A third form of framing strip has an integral window sash guide flange for replacing the conventional window sash guide molding found in older window constructions.
