A leather has on at least one of its surfaces a coating which covers a base leather. The coating takes the form of a cover layer (1) which planarises the base leather surface (4) underneath. This cover layer has at least at its surface (33) which is remote from the base leather surface (4) an appearance which predeterminably characterises the base leather (2). The cover layer (1) is composed of an...

Zum Entfernen des auf einem Garnträger (7) vorhandenen Fadenrestes (11) wird der Garnträger in einer Beladestation (A) der Vorrichtung zwischen einem Aufnahmekonus (6) und einem Anpresskonus (8) eingespannt, welche auf einem Schlitten (3) angeordnet sind, der auf einer Schlittenführung (1) oszillierend bewegbar ist. Bei dieser Bewegung passiert der Garnträger (7) zunächst eine Schneidestation (B),...

A yarn carrier structure upon which yarn is wound to form a yarn package (16) includes an axially extended body having a cylindrical exterior surface (14), formed about an axis (12), and a through opening (40), having opposed surfaces for engagement by the fingers (60,62) of a yarn package manipulating machine. Yarn entry ports (22, 24) are provided at one end of the yarn carrier structure and lea...

Common parts whose configuration is little are adopted to assemble a large area air collector array or a monomer. The utility model which can be extensively used for the heating of solar houses, solar drying places and other places by which a solar heat air system is needed has the advantages of material saving, flexible operation, high efficiency and low freight.

This invention is about solar enamel glaze. It is used for enamel products which can absorb solar energy. The silicon dioxide and boron oxide are usedas net-forming agent. Many compounds which can selectively absorb solar spectrum are used as filler and volume ion outside net. The extingction agent is added. The melting and sintering technology are same with that of ordinary enamel glaze. It is us...

PURPOSE:To enhance bonding properties, resistance to scratching and resistance to solvent by applying a comparatively thin film of specific coating on the surface of a mold and curing the same with ultraviolet rays or electron beam. CONSTITUTION:At least one of the molded surfaces is coated with one kind of polyfunctional monomer having three or more acryloloxy radical per one molecule and a monom...

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 drier has a drier body (11) and a stand (12) for supporting the body. The drier body (11) comprises a body head (20) having a heater (46,64,71) and a blast fan (63,70) driven by a motor (44,62,137) disposed from an intake port toward a blow-off port (32,72) side, and incorporates a collecting mechanism on the blow-off port (32,72). An handle (17) capable of pivotally supporting the body head (11...

1,1,1,4,4,4-Hexafluorobutane is used as a blowing and insulating gas in the production of plastic foams, preferably isocyanate-based foams, in particular in the production of polyurethane foams.

The invention relates to a front jaw for safety ski binding, having a compensation device for forces exerted by the ski boot vertically to the top of the ski. Elevated compressive forces exerted by the ball of the foot are compensated by a control element moved via a pedal plate which element acts directly on the slide part of the release spring loading the angle lever, or via a control element wh...

The additive contains a highly swelling, water-insoluble, highly polymeric substance as gel former which is coated with or dispersed in a water-soluble release agent which does not cause the gel-former particles to swell. The release agent is preferably a polyethylene glycol and is employed in an amount of from 10 to 100% by weight, based on the amount of gel former.

A retractable anchoring device for a sonde to be lowered into a well for logging purpose, is adapted to rigidly position the sonde at a preselected depth.
