There is provided an apparatus for supplying a bead portion in a tire-forming machine. The apparatus consists in carrying out the steps of assembling an inner liner, carcass ply and others in the cylindrical form of a band, transferring the band by band transfer means onto a carcass-forming drum arranged on the same shaft as said transfer means, incorporating the bead portion and a tread portion b...

In construction of a composite material for decorative applications such as eyeglass frames, adjusted addition of whiskers to metal matrix provides the product with light weight, rich anticorrosion, high strength and, rich elasticity. Additional core-to-sheath cladding further improves workability without any influence on the light weight characteristics.

Our invention pertains to various new compositions, methods for using such compositions and products treated with such compositions. Our new compositions include, among other things, certain antimicrobial agents solubilized with certain disubstituted aryl compounds.

A method for the recovery of plastic material such as polyester from scrap material such as photographic film having a polyester base and at least one layer of a macromolecular organic polymer. The process includes mixing small pieces of the scrap material in a solution having a scrap solids concentration level of at least 25 percent by volume. The mixture is subjected to conditions of high shear ...

A vehicle direction control device is provided including three receivers in the vehicle with the center receiver controlling the direction along a primary cable in the roadway with change of direction cable systems taking over control through a side receiver originally parallel with the main line of travel, diverging to a new direction and then picking up a parallel relationship with a new primary...

PURPOSE:To eliminate the need for warming up after throwing of a power source to an instrument by switching the circuits of an immobilized enzyme membrane reaction cell and the power source to change over battery charging or the impression of a voltage to the reaction cell from the battery. CONSTITUTION:The reaction cell P is constituted of the immobilized enzyme membrane and electrodes Pp and Pn ...
