Title: Electric conductors produced from metalsuper and - normal conductors
IPC: H01B12/10
Filed: 1969-04-03
Abstract: At least one part of the surface of a normal metal conductor (coating material) which is metallurgically joined to a super conductor is ultrasonically welded to another normal metal conductor (stabilisation material). Preferably the coated superconductor is completely incorporated into the stabilisation material. The superconductor is pref. Nb3Sn coated with Cu, Ag, or Al., Al or Cu being employed as stabilisation materials. The conductors are used to wind super-conducting coils partic. large super-conducting electromagnets.

Title: Laminated porous fabric of PVC on a support fabric - formed by melting PVC in a mould using a high frequency field and pressing the support fabric against it
IPC: B29C37/00
Filed: 1972-11-13
Abstract: A porous fabric (e.g. for shoe panels) is formed by applying a mixt. of PVC, an agent which causes porosity in PVC, and an absorbant powder to a mould, and melting using a high frequency electric field whilst pressing a porous support fabric against the mixt. so that the support fabric bonds to the mixt. The surface of the mould and the inner surface of the support fabric are opt. spray-coated with porous polyurethane films which bond to the support fabric and to the mixt., and a porous material, e.g. PVC foam, wadding, may be sandwiched between the support structure and the mixt. The mixt. may be pre-IR heated to bond the components of the mixt. together without solidifying it. The resultant polyvinyl chloride/support fabric material is porous to air, thereby making shoes produced from the material more comfortable to wear.
Patent FR-2233689-A1 (FR)
Title: Automatic control for resistance filament mfr. - continuously operating and reduces reject level
IPC: H01C17/22
Filed: 1973-06-13
Abstract: The automated control system for filament drawing and cutting in a continuously running process, results in electrically resistant fibres having diameters between 0.15 and 3.0 mm and length of between 3.0 and 6.0 mm and can produce about 10,000 pieces an hour. The reject rate using the proposed automatic control system is reduced considerably from the normal 60 to 70% level. As the filament passes through the sequential step-by-step drawing stages its transverse resistance is measured and compared with a required level using a 50Hz bridge, the output of which ultimately controls the rate of deposition of material onto the drawing collars.
