A magnetic core containing amorphous metal, suitable for use with electrical inductive apparatus, such as transformers, and methods of constructing such a magnetic core. The desired physical dimensions of the magnetic core are maintained, without adversely stressing the core, by a composite, conformal coating applied to the core edges. The composite coating includes a rigid high strength outer str...

A splicing head for a compressed air yarn splicing device has a splicing chamber with a yarn insertion slot opening thereinto and an arrangement by which a pair of compressed air entrance openings may be adjustabley located at differing dispositions with respect to the splicing chamber so that differing splicing air vortices may be selectively generated within the splicing chamber as required for ...

In order, in a fastening method for wear elements of a comminution machine, in which the wear elements have, on their side facing away from the wear region, at least one bearing eye having in each case one bore for an axle rod forming a fixed bearing for the wear elements, to eliminate the disadvantages connected with the removal of the axle rod and to provide a solution, which can be carried out ...

In a traction control system for motor vehicles, a lower limit for throttle opening degree command with respect to each gear position of transmission is set up, and when the transmission is shifted up, the throttle opening degree command is decreased down to the lower limit for throttle opening degree command corresponding to the gear position assumed through the shift-up operation.

A method and an assembly for decontaminating a material. The material is charged into a container (2), where at first steam (4) is introduced and fluids including some contaminants are removed. Then extractant (6) is introduced into the container (2), and fluids (8) comprising condensation water, extractant and contaminants are removed. Then the material is stripped with vapour. The dry or slightl...

PURPOSE:To cut a tire forming material smoothly by mounting a rotating arm on an elevatable mount shaft through a rotation control means, providing a rotary round blade on the tip end side of this rotating arm, and thereby swinging the blade along a steel cord with a minute lateral force to the blade. CONSTITUTION:On a shaft 17 for an elevating means 15 which shaft is supported by a guide rod 6, a...

The invention relates to a process for the production of a flameproofed foam in the form of a foam web. According to the invention, an open-cell foam web having a thickness of 5-50 mm is passed, in the compressed state, into an impregnation bath containing carboxyl-containing latex and zinc salt of a polymetaboric acid and/or aluminium hydroxide and is homogeneously impregnated while being relaxed...

Cover for mattresses or similar seating and lying surfaces for the incontinent, consisting of a piece (1) of stretch towelling material which, in the state of usage, covers the top side (2) of the mattress, surrounds its peripheral end faces (3) and ends in a seam at the underside of the mattress folding under the edge region of the latter, which seam contains an elastic cord holding the piece of ...

Polyurethane foam is modified by a post-treatment process comprising the steps of contacting the polyurethane foam with a swelling agent for the polyurethane foam and interpenetrating the swollen foam with a chemical additive, then shrinking the interpenetrated foam by removing the swelling agent under conditions where the chemical additive remains trapped in the polymeric structure of the foam.

A method for producing and distributing wet zinc dust to a zinc sulfate purification system or other zinc plant operation is disclosed. The method comprises atomizing molten zinc with high pressure water or other suitable medium, and feeding a predetermined amount of the wet zinc dust to at least one zinc sulphate purification tank or any other zinc plant operation.

PURPOSE:To prevent cracks in an insulating layer and separation of an interconnection layer from the insulating layer, by coating the insulating layer of a superconductor completely with the insulating layer. CONSTITUTION:A substrate 11 is coated with an insulating layer 13 having a predetermined thickness. The insulating layer 13 is formed of a composite oxide of yttrium, barium and copper. A pho...

PURPOSE:To form a sheet of superior flatness and smoothness by melting a formation composed of straight-chain high colecular polyarylene sulfide resin having melting viscosity of specific value or more or of mainly same resin, extruding the molten formation from a slit-shaped die and heat treating under the given condition. CONSTITUTION:A formation is composed of substantially straight-chain high ...
