A system for preparing and splicing two yarn ends has preparation nozzles in a turbulence chamber adjacent the end faces of a casing. The preparation nozzles improve the quality of the splicing by thinning the yarn ends. Compressed air or a partial vacuum can operate the preparation nozzles. With preparation of the yarn ends in the turbulence chamber for the splicing, the expenditure for a prepara...

Compositions having rodenticidal activity are disclosed which are constituted by a solution of a compound having anti-coagulant activity and which is an indane dione or a 4-hydroxycoumarin, preferably chlorophacinone, diphacinone, bromadiolone or coumachlor, in a glycol in admixture with a volatile co-solvent, preferably acetone or dichloromethane, which increases the solvent activity of the glyco...

Films consisting essentially of alpha-olefin polymers, such as normally solid polypropylene consisting essentially of recurring propylene units and having a substantial crystalline polypropylene content, and in particular isotactic polypropylene, are coated with a ketonic resin resulting from the polycondensation of aldehydes with ketones, which coating renders the films readily thermoweldable and...

Certain phenolic cellular materials of low thermal conductivity can be produced by having in the cells of the cellular material a synergistic mixture of trichlorofluoromethane and 1,1,2-trichloro-1,2,2-trifluoro-ethane in a molar ratio of 1:20 to 20:1.

In a compressed gas insulated high voltage switching installation, in particular, one with single phase metallic encapsulation, including bus bar systems and switchgear sections, with branches which are firmly anchored in space and in which compensators with tie rods are arranged in line with the bus bar systems, the longitudinal expansion of the housings of the bus bar systems is taken up practic...

The application discloses a process for making a polymeric powder which is readily dispersible in water to provide a composition useful for forming an enteric coating on pharmaceutical dosage forms and also a process for using the powder for its intended purpose.

The die (6) comprises a thick cylindrical body (7) which is surrounded by a cooling jacket (15) clamped against the pouring basin (2) and in contact with the latter in a plane (P). The body (7) is extended in the casting orifice (4) by a composite head (17) comprising a thin inner annular lip (22), whereof the inner surface extends that of the body (7) and a ring (24) of refractory material fitted...

In a computer network having a central computer, a plurality of peripheral computers, and a time-shared common memory accessible to the network computers over a single bus connected to the common memory, an electronic switch of the telephone type is connected to all of the computers so that direct links may be established between respective members of one or more selected pairs of computers. Data ...

Detergent bars and liquids/pastes for topical application are given moisturizing properties by the use of materials selected from dicarboxylic acids and their salts, hydroxy acids and their salts and amino acids and their salts. Examples are adipic acid, maleic acid and glycine; in the bars these moisturizing components are usually present at a level of above 20%.
