Wool is rendered shrink-resistant by: A. a preliminary mild oxidative shrink-resist treatment, preferably using a chlorine-containing agent, and B. treatment with a cationic polyelectrolyte, preferably a polyvinyl imidazoline, and with a polymer, e.g., a polyethylene, emulsion, so as to exhaust polymer on to the wool fibres. The treated wool can be dried below 100.degree.C and does not need to be cured.

A treatment device for various treatments including the alleviation of pain through the application of heat and/or cold, which can be applied in the home. The device comprises a container of moulded rubber or flexible plastics material having a generally horseshoe or U-shaped configuration with a stopped opening to allow the supply and removal of treatment fluid to, and out of, the container. The container further includes various forms of fastening means for attaching the device around part of ...

Given a group of radioactive concentrates including a concentrate from a resin-bead ion exchange filter, a concentrate from an evaporation concentrator, and a concentrate from another concentrator yielding a concentrate having a salt content lower than that of the concentrate from the evaporation concentrator and particles smaller than the particle size of the resin beads; a process including mixing the concentrate from the resin-bead ion exchange filter with the concentrate from the other conce...

Pharmaceutical composition containing therapeutically active 3-(parafluorobenzyloxy) benzoic acid successfully used in the treatment of thrombosis.

Apparatus for relaxing a running yarn composed of thermoplastic polymer material comprising a yarn supply means, a fluid tension device having a yarn passageway, means for introducing a gaseous fluid under pressure to the fluid tensioning device and a heating zone comprising an externally heated divergent passageway of a cross section steadily increasing from that of the yarn passageway.

Certain water-soluble copolymers prepared from divinyl ether and maleic anhydride have been found to suppress virus growth. Administration of said copolymers not only suppresses growth in infected animals but also increases resistance to virus infection in healthy animals by stimulating the production of interferon.

A shoe treatment machine in which a tool is provided which operates on the edge of the sole portion which is turned over the top of a last. The tool moves longitudinally of the last and which last pivots about a longitudinal axis so that the tool operates on the upper material near the periphery of the sole portion of the last. A control arrangement is provided operated by potentiometers which are adjustable in conformity with the size of the shoe last and with the longitudinal position of the t...

A process for the therapeutic and prophylactic tratement of allergy by the systemic administration of a compound of the formula: ##SPC1## Wherein ##SPC2## Is cyclohexane or ##SPC3## And X and Y can be the same or different and are hydrogen, fluoro, chloro, bromo, alkyl or from 1 to 8 carbon atoms, inclusive, or alkoxy of from 1 to 8 carbon atoms, inclusive, and the pharmacologically acceptable salts thereof in association with a pharmaceutical carrier.

Treatment apparatus for aerating or mixing, and clarifying, liquids such as industrial and sanitary waste waters and for conducting chemical reactions, in which an aeration or mixing basin and a clarifier are formed as one integral unit, separated by a baffle. Flow from the aeration basin into the clarifier is limited by flow control plates. The clarifier has a bottom which slopes toward the aeration basin bottom, so that solids settling in the clarifier flow down the clarifier bottom towards th...

Cellulosic materials are rendered water repellent by contacting a cellulosic material having a water content between about 2 and 7 weight percent with vapors of a lower alkyl silicon halide which reacts with water to form a siloxane and maintaining the cellulosic material and lower alkyl silicon halide in contact between about 0.1 and 8 seconds. The concentration of lower alkyl silicon halide and the temperature at which the contact is conducted are maintained so that the cellulosic material con...
