A system and apparatus for accurately delivering rubberized sheets from a supply roll of stock material containing an intervening liner to an assembly station for subsequent assembling into an air spring or similar article of manufacture by eliminating the heretofore formation of a "free loop" therein. The supply roll and a liner take-up reel are rotatably mounted on a carriage transversely movabl...

A self-emulsifiable resin powder can be dispersed in water without utilizing additional surfactants or expending large amounts of mechanical energy. Such self-emulsifiable resin powders offer numerous distinct advantages over conventional latices. One of the most important benefits that is realized by utilizing self-emulsifiable resin powders is that they can be shipped dry which is the equivalent...

Highly stretchable gel articles are prepared by contacting a shaped solvent-containing or solvent-free article of a high molecular weight polyolefin with a gaseous or liquid swelling agent at elevated temperature untill the swollen article contains 60-99 % (wt) of swelling agent, and cooling this article below the gelling temperature. The gel articles can be transformed into articles (filaments, t...

The subject of the present invention is an extensometer sensor (1, 1') for measuring stresses by means of gauges acting on a drilling element (50) at the bottom of a well. The extensometer sensor comprises: - a first measuring zone (10) composed of at least two tension leaves (11, 12, 13), on which are mounted measuring gauges connected at their ends by means of vertical members (14, 15), so...

Closed cell microcellular foam having cells with diameters of less than 10 .mu.m and preferably having a density is less than 0.1 gm/cm3 are prepared from copolymers of .alpha.-olefin and .alpha.,.beta.-monoethylenically unsaturated carboxylic acid. The copolymer is premeated with a blowing agent and ammonia at a pressure of 1.4 to 20 mPag in the presence of an inert gas and subsequently is heated...

The present invention relates to a remote actuator for a piece of equipment, operating by variation in the flow conditions of a possibly incompressible fluid, comprising an actuating piston (12) and a nozzle-needle unit (20, 21; 53, 57). This actuator is characterised in that one of these two elements (20, 21; 53, 57) is mounted so as to slide in the said piston (12), and in that it comprises mean...

La méthode selon l'invention comporte les étapes suivantes : - émission à partir de la surface d'une première séquence d'i...

PRODUCTION OF POLYIMIDE FOAMS A polyimide precursor mixture having a solids content of 50 to 77 (preferably 65 to 75) weight percent is subjected to a multistaged thermal treatment in which the precursor is heated to one or more temperatures sufficient to obtain a consolidated but friable cellular foam structure, and the resultant cellular foam structure is then subjected to one or more higher tem...

Oral compsn contg. a water-insoluble non-cationic antibacterial agent (I) is packaged in a dispenser in which it is in contact with a solid polymeric material (A) which is compatible with (I) and does not cause excessive losses of (I) during storage. (A) is a synthetic organic plastic, esp. PTFE (best) or polyvinyl chloride). If the compsn includes a terpene or flavouring agent as stabiliser for (...
