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...

This data processing system for a pattern generator receives data specifying each quadrilateral element in a pattern to be generated by laser scanning or other technique. The scanning is accomplished by swaths. In the preprocessor, separate vectors are produced for the portion of each quadrilateral edge in each swath. A real time processor, including a "pipeline" or cascaded set of beam processors...

An automatic selvedger has a pair of longitudinally spaced and transversely throughgoing main rolls rotatable about respective parallel axes and guides and a drive that pass the web longitudinally and continuously from one of the main rolls to the other main roll in a travel direction perpendicular to the roll axes and with the web spanned tightly longitudinally between the main rolls and lying ge...

A pneumatic yarn splicing device comprises a bracket, a yarn splicing member mounted on the bracket and having a pair of side faces and a yarn splicing hole extending transversely between the side faces, the yarn splicing member including an air ejection nozzle for ejecting a compressed air flow into the yarn splicing hole, and a pair of yarn presser levers pivotably mounted with respect to the br...

Process for applying a substance or a substance mixture to a twisted yarn, in which the substance or substance mixture, after being applied, is distributed to the outer and inner layers of the yarn, characterised in that the twisted yarn is temporarily untwisted at least essentially by means of a false-twist unit, is subjected to the substance or substance mixture in the untwisted state and is sub...

PCT No. PCT/DE85/00165 Sec. 371 Date Dec. 16, 1985 Sec. 102(e) Date Dec. 16, 1985 PCT Filed May 15, 1985 PCT Pub. No. WO85/05348 PCT Pub. Date Dec. 5, 1985.A yarn supply apparatus for textile machines has a yarn drum (5) carrying a storage winding (10), to which drum the yarn (8) can be supplied at a tangent via a supply guide element, and from which drum the yarn can be drawn off, extending towar...

In an electromagnet for a valve, the armature space under the pressure of the fluid is closed off relative to the winding of the electromagnet in the air gap by a pressure-tight seal which consists of a flange-like component and sealing rings. This improves the pressure-tight seal and higher internal pressures can be sealed off without hydraulic forces acting on the winding.

PCT No. PCT/FR83/00030 Sec. 371 Date Sep. 15, 1983 Sec. 102(e) Date Sep. 15, 1983 PCT Filed Feb. 15, 1983.An electrolyte for a lead acid accumulator containing 5 to 30 g per liter of pyrophosphoric acid and 5 to 50 g per liter of orthophosphoric acid, the total quantity of phosphoric acid in the electrolyte being less than or equal to 60 g per liter.

Efficient, high-precision machining of ceramic materials is achieved by supplying onto a workpiece of a ceramic material a liquid electrolyte having components at least one of which is normally inert to but becomes chemically reactive with the ceramic material at an elevated temperature, and applying to a limited zone of interface between the liquid electrolyte and the workpiece, localized energy ...

An optical control unit comprises a base and at least one optical assembly having optical emitting means and conjugate optical receiving means with preset and fixed focal distances, the optical emitting means and conjugate optical receiving means being associated with the base so as to have fixed orientations with respect to the base and be capable of movement in directions parallel and transverse...

A vehicle guidance system, in which vehicles are guided along a driving track, having a device for position identification in order to identify positions along the driving track and a device for recording information for controlling the direction of each vehicle along the track system. The device comprises an interrogation element for each vehicle having a coil which can be excited by a high-frequ...

A process and apparatus are provided for the treatment of waste polyurethane particles by alcoholysis or acidolysis. The particles are treated with a solvent at a reaction temperature within the range of 120 DEG C. to 200 DEG C. while being subjected to comminution until the particles are liquified. The resultant liquified product may be converted to a polyurethane by treatment with a polyisocya...

In a train safety device with intermittent and continuous automatic transmission of information between track and train, the trains request updated travel instructions from a control point when passing fixed influencing devices (P). These travel instructions are only acknowledged for as long as they are received in a cyclically repeated fashion; otherwise the vehicle travels according to a predete...

Highly soluble complexes of 2-(4'-thiazolyl)benzimidazole are prepared using glycolic acid. The aqueous solutions prepared therefrom are stable and may be used for anthelmintic and antifungal purposes. Additional compounds, especially other fungicidal agents, may be combined for compositions of broad spectrum.

A safety ski binding part includes a base plate having a roller supported thereon for rotation about a generally longitudinally extending axis, and a sole holder supported on the base plate for pivotal movement around a vertical axis and a transverse horizontal axis, the sole holder having a shoulder thereon. A lever supported on the base plate for pivotal movement about a transverse axis has a no...

The invention relates to a method for vulcanizing an elastomer (A), such as tire, fender, sleeve, hose, etc., set in a vulcanizing chamber by use of a mixed fluid comprising a low enthalpy gas (G) and a high thermal capacity thermal fluid (S), said mixed fluid being obtained by preliminarily mixing said gas (G) and said thermal fluid (S) by means of a mixer (4) or by introducing said gas and fluid...
