A method and apparatus for use at the stage of a radial tire building process at which a tread and breaker, and sidewall rubbers, are added to the expanded carcass. A tread assembly is built, comprising tread rubber breaker and sidewall rubbers and is then located around the carcass which is then expanded into the tread assembly. A tread assembly former has a central portion expansible to bring si...

A process for manufacturing an atomized amalgamable alloy having mold adaptation characteristics superior to other atomized alloys and comparable or better than those for ad-mixed type alloys (alloys which are mixtures of spherical and irregularly shaped particles), and physical properties comparable to ad-mixed alloys. The process includes the steps of: producing a melt of an amalgamable alloy; a...

PURPOSE:To prevent the internal corrosion and deterioration caused by the permeation of external water content, by coating with insulative material on the surface of a frame except the top parts of inner leads, and plating with metal on the exposed top parts of inner leads. CONSTITUTION:An adhesion tape is put on the tab part of a lead frame and the top parts of inner leads 5 (the part of dotted c...

Described is a hypodermic syringe which includes provision for a rigid sheath cover or sleeve which encompasses the rubber needle cover and provides protection in the operating mode as well as other advantages. The rubber needle cover is placed over the needle and provides a sterile barrier for the needle after the syringe unit is sterilized. The sheath cover can be made of plastic and includes a ...

For the preparation of a building and/or construction material a polymer modified, aqueous dispersion, containing amorphous silicon dioxide and at least one polymer, is mixed and reacted with at least one inorganic binder, and occasionally with at least one aggregate, and hardens thereby. The polymer modified, aqueous dispersion contains amorphous silicon dioxide and at least one polymer. This pol...

The invention relates to a device for the photoelectric measurement and recording of arbitrary and non-arbitrary eye movements by diffuse irradiation of the eye with IR light. It is especially applied in the medical field for investigation of the vestibular system and eye mobility and for determining the line of fixation. The object of the invention is to provide a nystagmograph by using the conve...

In pressurized, gas insulated, high voltage switching installations with single or polyphase metal encapsulation, a switchgear section comprises several adjacent pressure tanks having gas tight partitions for accommodating the high-voltage switchgear and other current carrying parts. The number of encapsulation tanks is minimized by arranging the switchgear and current carrying parts belonging to ...

An isocentric examination stand for radio-logical examinations of a patient comprising a cradle in the form of an arc of a circle which is circularly displaceable, a cradle support, an X-ray source and a radiation detector, the cradle being composed of mechanically assembled elements forming a structure defining the geometry of the cradle. The structure permits the passage of a supply cable of the...

PURPOSE:To improve the quality of a treated product by preventing scale formation by decreasing the dead space, by allowing juxtaposed trunnions so rotate in such a manner that the edge of the helical member of the impeller of one trunnion may sweep the zone near the rotation center of the other impeller. CONSTITUTION:While a highly viscous liquid to be treated, such as polyethylene terephthalate,...
