CONSTITUTION:When one end of a glass strand bundle 1 is tied to one end of another glass strand bundle 1, the on...

In order to provide a splicing device of universal use, the splicing chamber (18) has the form of a ring concentric to the thread axis (19). The ring has at least one switchable connection (16, 17; 20) to at least two energy carriers (14, 15, 21). One energy carrier is a compressed-air source (14). The other energy carrier or energy carriers are an electrical high-voltage source (21) and/or a suct...

Ruthenium-on-charcoal and ruthenium-on-carbon black catalysts, containing from 0.1 to 5% by weight of iron, for the preparation of olefinically unsaturated alcohols by selective hydrogenation of the corresponding alpha , beta -unsaturated carbonyl compounds in the liquid phase are prepared by modifying the catalyst with iron only after it has been impregnated with the ruthenium compound, and redu...

PURPOSE:To easily detect a fault of a shift path, by inserting a logic collating flip-flop for taking a known logical value, into a known position in a shift path loop. CONSTITUTION:In case when a shift mode signal is not applied, in a logic ''1'' collating flip-flop with a shift function, status of logic ''1'' is held, and a logic ''0'' collating flip-flop 2 with a shift function always holds sta...

An apparatus for releasing a safety ski binding comprising an actuation element intended to bear against the shank of the leg above the ankle bone. This actuation element may be operatively coupled directly or indirectly with an automatic release mechanism of the ski binding so that the latter is released through pronounced bending of the leg shank relative to the ski. The actuation element may be...

A measuring unit (E1) with an electro-optic measuring device which has a plurality of inputs and outputs (11, 12) for beams is arranged in a housing which can be moved on drive wheels (29). The measuring device serves for measuring the distances between the machine and measurement points in the walls which bound the room. The measured values determined are fed to a co-ordinate arithmetic unit (E2)...

Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block (1) which is provided with a protective layer (12 and 13) consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are di...

The herbicide phenmedipham is prepared from meta-aminophenol by reaction with phosgene in an alkyl alkanoate solvent to make meta-hydroxyphenylcarbamic acid chloride, followed by reaction of the chloride with methanol and then reaction of the obtained methyl meta-hydroxyphenylcarbamate with meta-tolyl isocyanate, to obtain the required methyl 3-m- toylcarbamoyloxyphenyl-carbonate.

This invention relates to a sterilized intravenous pharmaceutical container (12), and more particularly to a sterile flexible plastic seal (10) for resealing a pharmaceutical container (12) and for leaving a telltale mark (30, 32) on the container (12) when the replacement seal is removed. The flexible plastic cover (10) comprises a flexible plastic material forming a layer (40) substantially impe...

Apparatus for manufacturing powder, especially metallic powder, by a melt atomization process, comprises a closed container in which a jet of gas is directed transversely into a stream of the melt and breaks it down into droplets which rapidly solidify and are thrown in a parabolic trajectory to the lower part of the container. In the lower part of the container there is an inclined bottom or a sh...

PURPOSE:To automatically perform the simultaneous sticking of tape pieces in two ranks and to contrive energy saving by a method wherein tape pieces attracted to the lower ends of collets are simultaneously sticked to a semiconductor part in the front and rear ranks of two. CONSTITUTION:Tapes rolled out from a plurality of reels 11 arranged in parallel are cut to a predetermined length of tape pie...

For manufacturing a composite material, organic fibrous material like paper, straw, hay, grasses, moss, leaves, reed is mixed with alkali silicate and a fluosilicate as well as with a metallic oxide or a basic metallic silicate forming a higher melting silicate and submitted to a treatment under pressure and temperature. This produces a composite material having high mechanical strength and fire-p...

A cog-belt-driven power transmission device comprising a belt pulley having a cogging on the outer periphery and a belt having a corresponding cogging on the inner surface. In order to suppress the noise produced during rotation of the belt pulley one or more discharge channels for air entrapped between the coggings are made in the cogging of the belt pulley and/or the belt, said discharge channel...

An improved flexible cementitious material is prepared by mixing an aqueous dispersion or latex of elastomeric polymer (e.g. butyl rubber) with cement (e.g. Portland), allowing the mixture to harden typically for 28 days under conditions of high relative humidity, and thereafter compressing the hardened material (e.g. by passing the material between rollers) to reduce the brittleness and to increa...

A process for the precipitation of a pulverulent filled rubber, which comprises mixing a rubber latex, a rubber solution or a rubber emulsion with a filler suspension, waterglass and a water-soluble aluminum salt at a predetermined pH value of 3.0-3.7, the pH value being kept constant by introduction of acid during the precipitation.

The stocking time of perishable goods particularly certain food products in frigorific containers must be constantly controlled.
