A process for producing a filament or film of polyethylene terephthalate comprising forming a solution of polyethylene terephthalate in either phenyl ether or a mixture of phenyl ether and biphenyl, and more particularly a mixture of between 0 and 40% by weight of biphenyl and between 100 and 60% by weight of phenyl ether, extruding the solution through a spinneret or slot die, through air and int...

Until now, cars drive freely on the street and can therefore leave the carriageway or produce accidents by means of wrong human behaviour. It is the objective of the guide-rail car not to leave the carriageway and to exclude, as far as possible, erroneous human behaviour. The guide-rail car has the advantage with respect to conventional cars that it does not leave the carriageway in the event of h...

The invention relates to a process for producing foams that contain urethane groups in the presence of oligomers containing a plurality of fluoroaliphatic side groups and having a fluorine content from 5 to 30% by weight as surface-active auxiliary for improving the emulsifying effect, for regulating the cell structure and/or stabilising the foam, to the foams produced by the process, and to the u...

A binding coupled ski boot shaft delatching device is described in which the pivotable shaft 12 of the boot can be latched with the lower part 14 of the boot via a latching lever 20. The latching lever 20 is pivotable inwardly into a latching position by a sole clamp 64 against a spring force 34. In this way a falsification of the preset release characteristic of the sole clamp through possible in...

The invention relates to a sail containing a plastic film (sheet). The film is a transparent, biaxially stretch-oriented and subsequently thermofixed polyester film which carries, on at least one side, a waterproof coating containing a binder and optionally a dye. The invention also relates to a process for the production of a sail and to the use of the sail for propelling surfboards.

The invention concerns a method of automatically steering a self-propelled floor-cleaning machine along a predetermined path of motion on a limited area to be worked, wherein a sequence of path segments stored in a data memory is retrieved, and the path segments travelled by the machine, and wherein markings are recognized by at least one sensor and converted into course-correcting control command...

An electronic ski binding including orthogonal, obliquely mounted transducers for detecting oblique components of skiing forces applied to the binding. The binding may include isolation means for structure the transducers from the effects of ski bending. A means of mechanical compensation for the forces applied to the binding by the leaning of a skier may be included. A pivoted linkage between a s...

An asymetric membrane which comprises an at least partially crystalline aromatic ether ketone polymer may be prepared by contacting a solution of the polymer in a strong acid in a suitable shape with a non-solvent for the polymer.

A foundary mould or core is made by mixing a granular refractory material with 0.5-80% of a binder which comprises a 50-75 wt.% solution of a potassium alkali phenol formaldehyde resin and 0.05-3 wt.% (based on resin) of silane. The resin has a wt.: average mol. wt. (Mw) of 600-1500, a formaldehyde/phenol ratio of 1.2-2.6:1 and a KOH/phenol molar ratio of 0.2-1.2:1. The mixture is formed in a ve...
