Title: Device for the handling of drop wires in a warp-yarn drawing-in machine
Inventor: JAEGER SILVIO
IPC: D03J1/14
Filed: 1991-12-17
Abstract: Abstract The device for the handling of drop wires after the warp yarn draw in has taken place contains rail-like carrier members  (12) provided for lining up the drop wires and means (34) for displacing the drop wires in the longitudinal direction of the carrier members.  These means are arranged on the carrier members (12) and are formed by a threaded spindle (34) which is arranged on the edge, carrying the drop wires, of the carrier members and which can be driven rotatably about its longitudinal axis.        The handling of the drop wires, that is to say their displacement on the carrier members,  is thereby automated, and the stress on the warp yarns is kept as low as possible.     (Fig. 2b)

Title: Branched energetic polyether elastomers
Inventor: AHAD ELIE
IPC: C08G65/22
Filed: 1992-02-24
Abstract: ABSTRACT         The invention disclosed relates to novel branched chain hydroxy-terminated aliphatic azido polymers and copolymers with variable molecular weight (MW) and a single step method for the preparation thereof which involves respectively reacting a high (MW) 0.5 - 5.0 x 106) solid rubbery polyepichlorohydrin (PECH) homopolymer and epichlorohydrin/alkylene oxide copolymer (PEEC), with an alkali metal azide in a suitable organic solvent, in the presence of an initiator at elevated temperature.  The MW of the azido product may be controlled by including in the reaction mixture a basic degradation catalyst (such as LioCH3 or NaOH) and varying the amount of catalyst.  When the reaction is catalyzed, the MW of the product varies within the range 1,000 - 40,000 and the hydroxyl functionality is 2 - 10.  Uncatalyzed reactions yield products with MW between 40,000 and 200,000 and a functionality of about 10.  The branched azido polymers and copolymers yield energetic binders with improved mechanical properties and thermal stability which are useful in rocket propellants and composite explosives formulations.

Title: Resins having improved exchange kinetics
Inventor: PIKE WILLIAM C
IPC: B01J41/14
Filed: 1992-03-27
Abstract: ABSTRACT        Disclosed are novel ion-exchange and chelate-exchange resins having improved exchange kinetics for separating chemical species from liquids.  The resins are prepared from copolymer beads consisting of a monovinyl aromatic monomer and a cross linking monomer. The copolymer beads are functionalized such that weak-base exchange moieties are substituted at haloalkylated sites which are most accessible to diffusion into the beads, while hydrophilic, strong-base exchange moieties are substituted at haloalkylated sites which are least accessible to diffusion.  The resins have improved exchange kinetics due to shortened diffusion path lengths for the chemical species being separated and improved diffusion into the resin beads due to the hydrophilic, strong-base exchange moieties.     37,506-F

Title: Reformed casein micelles
Inventor: MELACHOURIS NICHOLAS
IPC: A23G9/32
Filed: 1992-06-05
Abstract: ABSTRACT    Reformed casein micelles are produced from an aqueous solution or dispersion of commercially available processed casein by the sequential addition, over an extended period of time, of calcium ions and a soluble phosphate salt, after which the aqueous reaction medium is concentrated such as by ultrafiltration or diafiltration, to increase the level of casein micelles thereon and remove excess salts.  The reformed casein micelles are used as a complete or partial replacement for fat in a variety of food products, particularly coffee whiteners.  Coffee whiteners containing reformed casein micelles as a replacement for the fat component have functional and organoleptic properties equivalent to conventional coffee whiteners.
