Abstract: A highly productive, continuous method for the production of room-temperature-curable organopolysiloxane compositions is obtained by continuously feeding 100 parts by weight of a diorganopolysiloxane with a viscosity at 25.degree. C. of 0.1 to 500 Pa.

Abstract: A device for continuously mixing liquid and powder is able to provide lower apparent viscosities for liquid-powder mixtures. The device allows introduction of a fresh supply of liquid in a second stage mixing chamber where a rotating disk further creates subdividing effects. This second stage mixing chamber contains scrapers with some having notches which help improve the powder dispersion in the resulting mixture.

Abstract: A novel tantalum compound represented by the formula (1): Ta(CH.sub.3).sub.3 (OR).sub.2, wherein R is an alkyl group having from 2 to 7 carbon atoms. The novel tantalum compound is produced by reacting a haloalkoxytantalum compound represented by the formula (2): TaX.sub.n (OR).sub.5-n, wherein X is halogen, R is an alkyl group having from 2 to 7 carbon atoms, and n is an integer of from 0 to 4, with a methylmetal compound; and recovering the tantalum compound represented by the above formula (1) by reduced pressure distillation. The tantalum compound has a high vapor pressure and permits effective formation of a uniform film of tantalum oxide with good properties by a CVD method. Therefore, the tantalum compound is very useful for manufacturing semiconductor devices.

Abstract: A canopy for a paraglider or a parachute. The canopy including upper and lower sides and a plurality of ribs extending between the sides and made of a mesh cloth. The upper and lower sides and the ribs define a plurality of cells which are arranged adjacent one another. Each of the cells has an opening at a front end thereof for introducing air into the canopy. The mesh cloth of the ribs includes large and small apertures disposed therein. According to one embodiment, either the large or the small apertures are arranged in matrix-like groups which are separated from one another by the other of the large and small apertures. According to another embodiment, the large and small apertures are disposed in groups which are arranged parallel to one another in the vertical direction.

Abstract: Continuous production of a long bias cloth is accomplished by manufacturing a tubular fabric on a circular loom having a circular frame, reeds arranged on the frame and a shuttle for a weft rotatable along the frame. The fabric is removed from the loom under tension by a removal device comprising a primary pillar core with a plurality of caterpillars adjacent its outer periphery. Removal under tension prevents the formation of any edge portion causing folds and wrinkles in the tubular fabric. The tubular fabric is then spirally cut by a cutting device which has a secondary pillar core with a plurality of feed rolls adjacent its outer periphery. The feed rolls are capable of moving the fabric forward relative to its length, while the cutter is capable of moving circumferentially relative to fabric lengbth. A long bias cloth of high quality can be manufactured continuously, even when the warp and weft fibers used have high-strength and poor or low elongation.
