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...

An apparatus (10) and related process for enhancement of woven and knit fabrics through use of dynamic fluids which entangle and bloom fabric yarns. A two stage enhancement process is employed in which top and bottom sides of the fabric are respectively supported on members (22), (34) and impacted with a fluid curtain including high pressure jet streams. Controlled process energies and use of supp...

A container for carrying a uniform, fan-folded stack of plastic sheet assemblies and for allowing the assemblies to be conveniently dispensed, one at a time, with minimal risk that the stack will become jammed. The stack of assemblies is retained behind a constriction within an elongated chamber having a corresponding shape and slightly larger size. Pulling the forward-most assembly through a narr...

A tire tread of elastomeric material formed into ground engaging elements (1) is provided with sipes (2) in said elements. The sipes are in the form of incisions. A first incision portion(s) extends inwardly from the tread surface and then splits into at least two incision portions (3,4) which continue to extend away from the tread surface while at the same time diverging apart from one another.

A power steering and limited slip differential system is provided with a main booster (14) generating a steering effort for front wheels (121, 122), a directional control valve (16) having a pair of reaction chambers (56, 57) and a friction clutch (26) disposed between a differential gear mechanism (25) and a driving wheel axle (119) for rear wheels (123, 124) and is further added with an auxiliar...

Method for building a carcass for a radial tyre on a flat building drum, the building drum being provided with radially expandable locking parts in order to radially press layers which form the carcass and are placed thereon, up to the bead rings intended for the carcass so as to secure the bead rings, while the outer diameter of these locking parts is smaller than the inner diameter of the bead r...

This apparatus has a bed horizontally movably supporting a top board for carrying the examinee, a gantry for X-ray tomography including a first X-ray source revolvable around the examinee and a first X-ray detector for detecting transmitted X-rays, a second X-ray source ...

The battery is mfd. by inserting the electrode plates and the separator plates in a battery casing before filling with sulphuric acid and a gelling agent, for forming a thixotropic electrolyte gel and subsequent sealing of the battery casing. The full amount of the sulphuric acid required for the battery electrolyte is filled in the battery casing after insertion of the electrode plates, with an a...

The composite component consists of an outer (1), core (2) and inner tube (3) in coaxial arrangement, with the core tube providing spacing between the outer and inner tube. The core tube contains recesses, forming ribs (4) of defined contour and cross-sectional dimensions. The core tube is firmly coupled to the inner and outer tube at the contact faces by material flux such that the component has ...

A device is described for temporary support of a residual pile of sheets to be printed during automatic pile change in the feeder of a printing press. It has fork bars (1) which can be introduced between the residual pile (3) and a pile carrier pallet. After transfer of the support of the residual pile (3) on to the fork bars, the old pallet is removed, and a new pallet and new pile (8) placed on ...

A magnetic tape wind-up control method comprises the steps of controlling the speed, at which a feed motor is rotated, in accordance with a signal generated by a tape movement detector, and controlling the speed, at which a wind-up motor is rotated, in accordance with a signal which represents the position of a dancing arm, which thereby controls the tension on the magnetic tape. The number of rev...

A method for disinfecting contact lenses comprises contacting the lens with an isotonic aqueous solution comprising an effective disinfecting amoutn of tromethamine (preferably 0.6 to 2 percent) for a time sufficient to disinfect the lens. Other aspects include adding to the solution from 0.01 to 1 weight percent chelating agent (preferably disodium EDTA) and/or additional microbicide.

The circuit arrangement comprises, for each bit location in a column of the RAM, an input shift register, a multiplexer and a comparator. The input data bit is stored in the shift register, and the multiplexer is arranged during a write cycle, to write the data bit into the bit position. During a verification cycle, the multiplexer is arranged to write the inverse data bit into the same position, ...
