Binding of the webs to the fabric may be effected by an adhesive, welding or vulcanization e.g. by a self vulcanizing adhesive or by adhesive containing a vulcanizing agent. The plies of the double fabric which may be made from natural fibres, rayon, polyester, polyethylene, polypropylene, polyamide, polyvinyl alcohol, glass or metal fibres or mixtures thereof. A preferred double fabric has warp, weft and pole threads which differ from each other in their materials and thickness. A further preferred double fabric is made by intercrossing the spacer threads with warp and/or weft threads of the upper and lower plies thereof; alternatively, the double fabric may comprise common warp threads woven into the upper and lower weft threads and forming the spacer threads. The plies of the double fabric may be connected to the coatings of the upper and lower webs by adhesion, welding or vulcanization, alternatively, stitching may be used. The coating material may be rubber, synthetic rubber e.g. polyisoprene, polybutadiene, an acrylonitritebutadiene copolymer; a styrene-butadiene copolymer, chlorosulphonated polyethylene, polyethylene, polychloroprene or an ethylenepropylene terpolymer. Alternatively, a plastics material e.g. plasticized polyvinyl chloride or an ethylene-vinyl acetate copolymer may be used.

Abstract: 1,058,037. Electron beam apparatus. NIHON DENSHI KABUSHIKI KAISHA. Nov. 3, 1964, No. 44834/64. Heading H1D. The chemical properties and geometric configuration of a solid specimen is investigated by using one or more semi-conductor, elements each having a P-N junction for analysing the electrons emitted by the specimen under electron beam bombardment. The electron irradiation of the elements produces a photo-voltaic effect, the strength of the signal produced being dependent on the intensity of the incident electrons. The electrons detected may be backscattered electrons or transmitted electrons that have passed through the specimen. The electron beam may be scanned over the surface of the specimen, and an oscilloscope display formed by a synchronized scan modulated in brightness according to the signal produced by the detecting element. The detector may be mounted on the electron-optical elements controlling the beam, the detector having a central opening for passage of the beam. The detector may be adjustably positioned near the specimen, and two or more detectors may be provided.
