An actuator driven by D.C. power suitable for use in actuating automobile door locking device. The actuator has a yoke apparatus defining a space, two annular solenoid coils supported and received by the yoke apparatus and adapted to be energized simultaneously such that poles of the same polarity appear at the adjacent ends of the coils, and moving means reciprocatably disposed in the space of th...

The method involves the use of two nozzles (5 and 6) which alternatively blow air jets against a yarn in the central portion of a channel (1), these nozzles being symmetrically placed in relation to a plane containing the channel axis. The jets blowing frequency is of several hundreds of Hz. A deflector (3) in the bottom of channel (1) can deviate the beating thread sidewise and consequently impar...

A continuous flow device for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the useful commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of ...

Automatic memory tester apparatus for processing failure information of a memory under test (MUT) including a high speed pattern generator for providing digital test patterns to the MUT for storage of data at MUT addresses in the MUT, a failure processor for comparing outputs from the MUT with expected outputs to obtain failure information, and a fail map random access memory (RAM) having fail map...

Paint compositions suitable for forming decals which can be applied to vehicle tire sidewalls. The compositions comprise a saturated elastomer having a glass transition temperature not higher than -40 degrees C., a pigment which is preferably titanium dioxide in an amount in the range of 0.5 to 10 times the weight of elastomer, and a solvent. Compositions of this invention are resistant to ultravi...

A sealing cap for a bottle or other container comprises a tubular body and a plug disposed within the through-bore of the tubular body. The plug is displaceable within the through-bore from an initial position in which it seals the through-bore, to an intermediate position in which it is a loose fit so that the container may be evacuated through the body, and then to a final position in which it s...

A specific elastomeric composition is formed by melt blending two particular elastomers, each composed of hard and soft segments made from poly(tetra-methylene ether) glycol, 1,4-butane diol and a phenylene dicarboxylic acid or a derivative thereof. The blend exhibits a melting endotherm that extends from no lower than 120 DEG C. to no higher than 215 DEG C. with a melting peak in the range of 15...

A stabilizing composition and process for guayule type rubbers which can be directly applied to guayule-type plants or shrubs before processing thereof, or to guayule-type rubber miscella, rubber-resin miscella, etc., contains a volatile low melting point antioxidant which is either liquid or solid and an optional liquid inert carrier which lowers the melting point of the antioxidant. Since antiox...

The invention relates to a process for the production of concrete building products having thicknesses in section of not greater than 15mm in which a cementitious composition comprising (i) aggregate, (ii) hydraulic cement, and (iii) water is shaped by a roller and slipper method to produce a shaped extrudate which is divided to form sections and the sections are cured to provide the building prod...
