The invention relates to the heel retainer of a ski binding, in which a vertically pivotable sole retainer is held in the skiing position by a locking lever. The purpose of the invention is to design such a heel retainer in such a manner that it can be opened, optionally with the aid of a conventional release lever, against the force of the release spring, but especially by means of another actuat...

The invention relates to a heel hold-down of a ski binding, in which an upwardly pivotable sole hold-down is held in the skiing position by means of a catch link. By means of the invention, a heel hold-down of this type is to be constructed in such a way that inadvertent, arbitrary release is impossible, but arbitrary release at a considerably reduced spring force is possible when a depression is ...

Mirror objective comprising two reflecting surfaces (2, 3), a primary mirror and a secondary mirror, respectively, arranged in connection to a lens (1). The primary mirror and the secondary mirror together with the lens are arranged to form an excentric radiation path through the mirror objective. The optical axis of the mirror objective follows an N-shaped path through the objective and central d...

The invention relates to a reactor for the manufacture of a synthesis gas by partial combustion of a carbon-containing fuel. The reactor comprises a device (10) for creating, and maintaining, a layer of water along at least a part of the inner surface (14) of the wall (2) of the reactor chamber (1).

Cementitious composite materials having high strength, vacuum integrity, good thermal properties and low coefficient of thermal expansion are prepared from a mixture of 1) a high strength cement matrix, and 2) a filler component, comprising a metal fiber. These composites are useful in the manufacture of molds and tools for forming metals and plastics. A preferred composite mixture compris...

Atomized metal is made from a source of molten metal which is fed into a vessel in finely divided particles, said vessel having a sidewall terminating in an endwall through which atomizing gas and molten metal are introduced from an external source to said vessel through a nozzle sealed to said endwall, a gas ingress port therein being spaced from side endwall. The sidewall, endwall and nozzle coo...

The invention relates to an atomisation nozzle intended more particularly for the metallurgy of metal powders and alloys by means of a high-pressure gas improved by the addition of an aerodynamic device which centres the jet of liquid and prevents it rising during or before or after its atomisation on the liquid-supply spout or on the nozzle. This device is aimed particularly at high-performance n...

L'INVENTION CONCERNE UN FIL ELECTRIQUE ISOLE DESTINE A LA TRANSMISSION DE SIGNAUX ELECTRONIQUES.

LE FIL ISOLE CONSISTE EN UN FIL METALLIQUE RECOUVERT D'UNE MOUSSE DE COPOLYMERE PERFLUORE DE TETRAFLUOROETHYLENE, FACONNABLE A L'ETAT FONDU, ET D'UNE PEAU NON EXPANSEE, ENTOURANT LA MOUSSE, CONSTITUEE D'UN COPOLYMERE D'ETHYLENECHLOROTRIFLUOROETHYLENE OU D'UN COPOLYMERE D'ETHYLENETETRAFLUOROETH...

Process for fabricating cement-bound wood fiber mould bodies, wherein a mixture comprising a certain content of Portland cement, water and wood chips or wood wool and optionally the usual additive is moulded and hardened under pressure and optional heating up to the deformation resistance.
