Air permeable wear-resistant insoles comprising a web or matt layer of fibres, bonded with active carbon and bonded thereto a wear-resistant fabric which is different from and has greater wear-resistance than said web or matt layer, in which the ply bond strength of the said bond between the wear-resistant fabric and the said matt or web layer is greater than the ply bond strength of the matt or web layer itself, said insoles being produced by forming a web or matt of fibres loaded with active c...

A chipboard having bonded thereto a sheet metal lamination is disclosed. The sheet metal stretches and contracts in response to dimensional changes in the chipboard without becoming detached therefrom, thereby improving and preserving the strength and integrity of the chipboard. Also disclosed is a method of manufacturing thin laminated chipboard wherein a thermoplastic material, securely connected or bonded to a sheet of non-thermoplastic material, is laminated to the chipboard by contacting th...

Laminated composite consisting of a substrate sheet coated with a film (A) comprising at least one layer based on a polyamide resulting from the polycondensation of an aliphatic .alpha., .omega.-dicarboxylic acid with xylylenediamines.

There is disclosed an improved wiper head which includes a laminated wiper including a plurality of discrete layers of a fibrous material and means for bonding the layers to provide a unitary structure. A wiper holder is mounted adjacent an exit end of a tank and includes structure for supporting the wiper in a path of movement of the wire so that the wiper removes excess plating material from the wire.

Clothing material made from a layer of polyurethane foam having heat reflective material flame bonded to one face and weatherproof fabric flame bonded to the other face. The invention also includes clothing made from the material.

A flexible belt having an outwardly facing surface, a welded seam having irregular protrusion on the outwardly facing surface and a thin flexible strip laminated and covering the welded seam and protrusions. This belt may be fabricated by providing a flexible belt having an outwardly facing surface and a welded seam having irregular protrusion on the outwardly facing surface and laminating a thin flexible strip to the welded seam. This belt may be used in an electrostatographic imaging process.

The invention disclosed is a multi-layer silver/silver chloride electrode structure for use in electrolytic cells, particularly at low temperatures. Each layer includes an evenly dispersed matrix of metallic silver bonded to silver chloride particles, compressed onto a metal grid. A method for the manufacture of the electrode is also disclosed.

A process is described for the preparation of laminated doughs, wherein the laminated dough has a number of fat layers having a different thickness. Such a dough is obtained by a process wherein the total amount of lamination fat is divided over several lamination steps. The invention is also concerned with a laminated dough, optionally in frozen condition and with baked products, obtained after baking of the dough.

A laminated ceramic superconductor which comprises at least two layers of ceramic superconductor and a stabilizing metal layer interposed between said ceramic superconductor layers, which has improved flexibility and increased critical current density.

A laminated packaging material from which package type containers are fabricated for storing or transporting a variety of products ranging from dry food-stuffs to electronic equipment where maintenance of a dry environment is a requirement, comprising an outer imperforate water impervious layer, a middle layer of absorbent material and an inner perforated moisture impervious layer.
