A selectively positionable fluid conduit for gas removal from or gas introduction to a specific environment is disclosed. The fluid conduit includes a tubular wand having an orifice at the distal end thereof. Unwanted gases are removed by suction force through the orifice. Desirable or therapeutic gases are introduced to a specific location through the orifice. The tubular wand is coupled to a mal...

Revêtement antiusure constitué d'un tel nitrure de titane dopé par du bore. Pièces, par exemple pièces métalliques, pièces en carbure de tungstène et cermets, comportant un tel revêtement.; Titanium nitride doped with boron has a cryst...

Amorphous metal oxide barrier layers of titanium oxide, zirconium oxide and zinc/tin oxide are effective as alkali metal ion barrier layers at thicknesses below 180 Angstroms. The amorphous metal oxide barrier layers are most effective when the density of the layer is equal to or greater than 90% of the crystalline density. The barrier layers prevent migration of alkali metal ions such as sodium i...

A process for the treatment of a liquid reactive medium with a gas comprising dispersing the gas in a liquid in which the gas is sparingly soluble to form a dispersion thereof, said liquid being maintained at a pressure (P1) greater than the pressure (P2) of the liquid reactive medium and the amount of said gas dispersed therein being in excess of its saturation point in the liquid; and introducin...

A 4-methyl-1-pentene resin composition comprising (A) 20 to 60 parts by weight of poly-4-methyl-1-pentene or a copolymer chiefly composed of 4-methyl-1-pentene, (B) 30 to 60 parts by weight of an ethylene/butene copolymer, (C) 5 to 40 parts by weight of poly-1-butene or a copolymer chiefly composed of 1butene and another .alpha.-olefin, and (D) 0 to 30 parts by weight of a propylene/butene copolym...

Lumbar protector with underpants incorporated, including a pair of underpants; and a closed band sewn to an upper part of the pair of underpants and having a band height such that the band covers at least lumbar vertebrae of a user, the band being produced in natural textile fibers with a significant caloric effect and at least ten per cent selected from the group consisting of elastomeric polyure...

A method and apparatus for reducing noise in optical communication systems, wherein the frequency of light output from a signal laser is modulated or dithered to broaden the optical spectrum of the signal laser. The broadening allows error-free data transmission within signal bands, despite the presence of optical beat interference. Different dithering tones are emitted by each laser in the networ...

The device includes at least two pairs of partially through holes (19) which are so arranged that the hole centre line is closely connected to a track (17) edge. The holes in the pairs are separated and centred around the track centre line (22). The holes partly issue out into the track and a resistance (21) is formed by residual material at the track edge. A ball (18) is arranged in each hole (19...

The system is of the combination type, handling several cables at the same time. It is provided with a combination arm (97), which orientates and positions several cables and cable ends. It is provided with several orientation components (84) and with several movable jaws (80) controlled by cylinders (81). The combination arm positions the cable ends in joining casings by moving away from each oth...

In order to obtain a crop which provides an increased storage lipid content in its seed, the activity of cytosolic pyruvate kinase of a seed is substantially lowered as compared with the endogenous activity of pyruvate kinase in the plant seed. Preferably, the activity of phosphoenolpyruvate carboxylase is substantially lowered as compared with the endogenous activity of phosphoenolpyruvate carbox...

A package of the present invention comprises a base molded integrally with a lead frame by resin, a chip mounted on the lead frame, and a cap made of resin, which covers the chip and is fixed to the base. The base includes a substrate portion sealing the lead frame therein, a frame-shaped bank portion formed at a periphery of an upper surface of said substrate portion, the bank portion having said...
