In order to wind a newly joined thread onto a tube newly inserted on a spooling device on an open-end spinning mechanism, the newly joined thread, together with a thread portion containing a leader, is guided away before the start of the bobbin build-up. Thereupon, the thread portion containing the leader is severed from the thread, and subsequently, the thread supplied by the open-end spinning me...

Apparatus for making metallic glass powder is disclosed, which involves atomizing a jet of molten glass forming metal alloy by impinging with a moving body to form a stream of discrete molten droplets of the metal alloy, followed by impinging that stream on a travelling chill surface to effect rapid solidification of the molten droplets. The powder can be fabricated into solid articles.

An organic, high-molecular weight polyester containing substantially chain members of the formula -O-X-O-Y- wherein X is at least one member of the group consisting of and Y has the formula having an inherent viscosity of at least 1.0 dl/g, preferably at least 1.2, dl/g measured at 30 DEG C. in a solution of 0.5 g of the polyester in 100 ml of a mixture of 60% by weight of ph...

Liquid hydrocarbon fuel compositions are provided containing antiknock quantities of ashless antiknock agents comprising selected bicyclic diolefins such as norbornadiene.

Attorney Docket BWC-139-A IR-2010 IMPROVED ENERGY MANAGEMENT FOAMS The damping characteristics of cellular polyurethane foam products is controlled by the catalyst levels present in the foam formulation. The introduction and use of high catalyst levels in the formulations reduces the individual cell size of the foam product, thereby increasing the damping characteristics thereof.

A pressure measuring section is arranged between a pipe section connected with an injection pump and a pipe end section or portion. The pressure measuring section is provided with a pressure measuring location which is determined by a measuring chamber arranged internally of a housing portion. Within such measuring chamber or compartment there is located a pressure-impinged portion of a pressure m...

A disc brake 10 has a caliper 34 including apparatus 52 for retracting the piston 68 of the fluid motor portion 44 of the caliper to a non-braking position when the brake is not applied. Consequently, runout, wobble, or axial movement of the brake disc 12 may space the friction elements 62, 64 of the brake from the friction faces 18, 20 of the brake disc so that the friction elements do not drag o...

In bonding molded articles of a 4-methyl-1-pentene polymer to each other or bonding a molded article of a 4-methyl-1-pentene polymer to a molded article comprised of a vinyl alcohol type polymer, metal or glass, if a solution of a modified 4-methyl-1-pentene polymer in cyclohexene and/or carbon tetrachloride is coated on at least one of the molded articles to be bonded, the adhesion strength can r...

This invention is a method of manufacturing polyester fibers with good adhesion to rubber, characterized in that in the process of spinning polyester fiber, a spinning oil (finish composition) containing an epoxy compound and the compound expressed by the general formula (where R is hydrogen, an alkyl group, a cycloalkyl group, or an aryl group; M is an alkali metal or an alkaline eart...

Disclosed are low density foam planks of ethylenic polymers, which planks have a density of from about 0.8 to about 1.6 pounds per cubic foot, dimensional stability, substantially closed-cell structure, a cross-sectional area of at least six square inches and a minimum cross-sectional dimension of at least 0.5 inch. Such foam planks are made from polyethylene resins (e.g., low density polyethylene...

An improved process for the foaming of polyolefin materials is disclosed where the polyolefin is crosslinked by a peroxide and foamed by a chemical foaming agent combined with an auxiliary foaming agent is disclosed. According to the invention, the auxiliary foaming is a sterically hindered phenol and/or an organic phosphorus compound.

A molded article which consists of a core comprising a copolymer of a monovinyl aromatic monomer and an alpha, beta-unsaturated cyclic anhydride and a grafted water-swollen hydrophilic polymer coating on the core is particularly suitable for use as a blood-contacting article.

The device makes it possible to optically inscribe and/or read at least two facing sides of disks in an optical memory system, whose disks are stacked. A linear motor displaces a mobile means incorporating recording-reading heads. These heads receive via a bidirectional optical connection data to be inscribed and coming from fixed light emitters-receivers. Each of the recording heads comprises two...

An oriented heat-sealable antistatic polypropylene film is manufactured by applying to one or both surfaces of a base polypropylene film, preferably by co-extrusion, a layer of a heat-sealable olefinic polymer (for example, a predominantly linear random copolymer of ethylene with butene-1) containing between 0.2 and 10% by weight of an anionic hydrocarbyl (preferably long chain alkyl) sulphonate. ...
