Fabric is treated to give it softness by subjecting the fabric to intermitternt mechanical shocks submitted with an abrasive device across the width of the fabric. Sustained contact of the device and the fabric is not maintained, and the shocks are provided at a force and frequency sufficient to alter the fabric surface uniformly. Film and paper may also be treated by the process. The process offe...

A ski fastener structure has a rigid bar element removably fixable to a ski and engaging the lower end of a rod element pivotable about a horizontal axis substantially perpendicular to the ski longitudinal axis. The rod element is effective to resiliently encircle a rear region of the skier's leg at the middle area of the tibia and the skier's footwear is removably connected to the bar element.

Polyesters are combined with UV-stabilizing substances in order to produce an end product, such as a film, sheet, ribbon or filament, by mixing polyester granules and the UV-stabilizing substance in powdered form at an elevated temperature such that at least the exterior surface of the polyester granules is soft, thereby to cause the powdered UV-stabilizing substance to adhere to the individual po...

A process for the production of a moldable fibre-containing cementitious composition in which at least one mat of a water-insoluble fibrous material is contacted with at least one surface of a shaped article of a moldable cementitious composition, the cementitious composition comprising a homogeneous mixture of at least one hydraulic cement, water in a proportion of not more than 25% by weight of ...

The invention proceeds from a device for sealing off a pressure vessel, especially a piston bore (2) of a floating caliper disc brake, in which an operating piston is carried in a cylinder bore (2) of a housing (1) forming a seal. The operating piston can be displaced by a hydraulic pressure, one end face of the operating piston defining a working chamber (3) to which pressure can be admitted. A s...

Preparations of insoluble colorants, especially pigments, are obtained by distributing the colorant in molten polypropylene wax having a viscosity of 0.5 to 5 Pa.s, determined at 170 DEG C., and an isotactic proportion of 40 to 90% by weight. These preparations are easily dispersible in polyolefins and especially useful for dyeing polypropylene in the mass.

The present invention relates to a materials handling car in which the means for actuating the braking system comprise a progressive-action handle 8 situated near the steering wheel 2 while the accelerator is placed under the control of a throttle valve 10 which the driver can actuate with the hand in which he is holding the handle 8, this throttle valve being movable to either side of a neutral p...

This construction material based on a hydraulic binder, such as cement or plaster, contains as an additive an expanded thermoplastic material, in particular expanded polystyrene.
