Apparatus for examining a human patient by means of penetrating radiation has a source of radiation for producing a sectoral swath of radiation which traverses a planar slice of the patient and is then measured by a bank of detectors each of which is sensitive to a narrow beam of the radiation in said swath. The swath of radiation is produced by a rotating anode Coolidge tube and means are provide...

PURPOSE:A clutch brake operation apparatus capable of easy handling of the apparatus and capable of setting the clutch and the brake to the off state, keeping the advantage possessed by the lever removing type between two positions.

PURPOSE:To provide a clutch and brake controlling mechanism, which is provided with a timing regulating device so that proper operation of clutch and brake can be achieved in accordance with various conditions under which a vehicle is conducted, for example, when conducting it at a high speed, on a slope or in a narrow space.

A surgical instrument in particular for eye surgery has a housing having a good surface for placement on the eye. A knife is held retracted within the housing under the bias of a torsion spring. An ultra-sonic transducer measures the thickness of the part of the eye local to the surface. A control system responds to the measured thickness to displace the knife to project from the surface by an amo...

PURPOSE:To improve the working efficiency and to obtain a tire good in uniformity, by projecting a bead wire supporting mechanism when the expansion of a bladder film that approaches the end of the tire molding drum due to the expansion is temporarily stopped. CONSTITUTION:A carcass ply band 4 is mounted onto a drum 1, a bead wire 6 is placed at the pressing position, and a bladder 11 is expanded ...

TIRE TREAD FORMING METHOD AND APPARATUS A body having rubber material thereon is positioned on a lower member, and an upper member is moved toward the lower member, such relative movement causing tread-forming shoes to move to inward positions to form a tread on the rubber material. As an alternative, the upper and lower members may be brought together, and rubber material may be injected into po...

A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member. The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag. After the core is pressed coaxially on the tie strip so as to indent the member and thus pr...

Novel foamed thermoplastic compositions are disclosed that comprise a polyester resin, such as poly(1,4-butylene terephthalate); an ionically crosslinked copolymer of an alpha -olefin and an alpha , beta -ethylenically unsaturated mono- or dicarboxylic acid, and a polytetrafluoroethylene resin.

There are provided low temperature, storage stable, liquid mixtures of (1) isocyanato-containing prepolymers obtained from the reaction of linear and/or slightly branched polyols and a polyisocyanate characterized by a methylene group (CH2) bonded to two benzenoid nuclei, and (2) a non-hydroxyl-containing flow modifier which is compatible with the said prepolymer. Novel liquid mixtures thus prepar...

Colloidal aqueous dispersions of rosin possess improved mechanical and heat stability when they have a small dissolved content of a water-dispersible emulsifying agent selected from the group consisting of tetrasodium N-(1,2-dicarboxyethyl)-N-octadecylsulfosuccinamate, disodium N-octadecylsulfosuccinate, disodium dodecylpenta(ethoxy) ethylsulfosuccinate, and disodium decylsulfosuccinate as stabili...
