An improved bicycle tire which can be folded for storage and transportation while maintaining the same running properties as a conventional tire. A plurality of bead cores made of a cord tensile member embedded in the bead section of the tire are provided by winding three to five turns of a cord tensile member having a low elongation ratio and high strength and which has been twisted one to two tu...

A tire (10) produced via a molding or casting process in a manner such that each of its bead areas (16) includes an annular slot (42) whereby the slots permit the insertion of an inextensible annular reinforcement element (40) into each of the bead area slots (42) after the molding or casting process. Slots (42) are preferably produced by the addition of annular collars (64) to either the outer me...

A method and apparatus for recovering heat and volatilized fluid contaminates or smoke from an airstream, and which includes continuously spraying a fluid, such as lightweight oil, into the airstream, collecting and cooling the sprayed fluid and any condensed contaminates, and recirculating the collected and cooled fluid and condensed contaminates to make-up the fluid which is sprayed into the air...

A laser output measuring device for a laser knife having a flexible manipulator in which the output power at the operating end of the manipulator is accurately displayed at all times independent of changes in the transmissivity of the manipulator. A measuring hole member is provided in a housing in which is positioned a laser oscillator, a shutter device and a power detecting device. When the end ...

A die (12) for extruding an elastomeric ribbon (14) reinforced with laterally spaced longitudinal filaments (13), said die having mating die blocks (17 and 18) enclosing mating die plates (15 and 16) embracing a filament guide insert (25), and said insert being undercut at (38) to form a flat surface (39) having exposed grooves (42) which are extensions of the filament guide passageways (26), wher...

The present invention relates to open- and/or closed-cell elastomeric foams and to a method of production thereof. In particular there is provided an open- and/or closed-cell elastomeric foam produced by foaming a polyurethane and/or polyurea-prepolymer capable of being cross-linked with a polyamine chain-lengthening agent in the presence of an expanding agent characterized in that the expanding a...

The device, which is connected to an element to be displaced, comprises a tubular body surrounded by sleeves which are inflated to a diameter slightly smaller than the diameter of the conduit. A motor-pump assembly located in the tubular body provides for the circulation of the fluid through the body so as to cause propulsion of the device within the conduit. Sensors may control automatic operatio...

A package comprised of (A) reclaim rubber packaged in (B) a protective film of thermoplastic ethylene/acetate copolymer, the use of such a package for the purpose of compounding additional rubber and such compounded rubber. A method is also provided for compounding rubber using the packaged reclaim rubber of this invention and rubber and compound ingredients for the rubber which are also packaged ...

A process for forming a polymeric foam comprising mixing a liquid multi-functional acrylate monomer and a liquid nonionic fluoronated alkyl-ester surfactant, foaming the surfactant monomer mixture and passing the foamed surfactant monomer mixture under a source of electron beam radiation to polymerize the monomer into a polymeric foam structure.

Film of a wholly aromatic polyamide, at least 85% of the repeating units of which are meta-phenylene isophthalamide units, which is undrawn and noncrystalline and which has improved impact strength. Such film is made by heat-treating film of the polyamide which is undrawn and noncrystalline at 400 DEG to 300 DEG C. for from 2 seconds to 2 minutes while maintaining the film at constant length and...

An edible suspension of a finely divided food material in a liquid suspending medium which swells cellulose, the suspension also containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension. The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater sta...

By mixing and reacting an alkali metal silicate, a substituted monohydroxy organic compound and a polycarboxylic acid and/or polycarboxylic acid anhydride, polyester silicate resinous products are produced which may be utilized as molding powder, coating agent, etc.

In a method of eliminating interaction between neighbouring cells in gas-discharge matrix elements with noble-gas filling, aliphatic alcohols containing 1 to 5 carbon atoms, low-molecular-weight saturated or unsaturated aliphatic hydrocarbons containing 1 to 7 carbon atoms and/or aliphatic ketones containing 3 to 5 carbon atoms are added to the noble-gas filling in low concentration. For a noble-g...

Ultra-high molecular weight polyethylene powder is heated at a temperature between its crystalline melting point and about 275.degree. C for a short period of time ranging from about one minute to about thirty minutes to obtain a molding powder having properties which facilitate the subsequent step of compression molding. Compression molded pieces made from heat-treated powder have better transpar...
