A bipolar module for lead/acid accumulators has a central metal plate surrounded by a plastic or rubber frame coated on one or both sides with a very thin layer of platinum or a metal from the palladium group, or an alloy thereof, like nickel/palladium. One or both sides of the plate also has a thin layer of silicon, silicon nitride, silicon carbide or silicon bronze. On the positive side, the pla...

The invention relates to an arrangement for driving a cutting blade (7) for cutting a document printed in printing means on a strip-like recording carrier (1). The cutting blade (7) is attached to a carriage (6) which is driven by a step motor (12).

The device consists of a limited elastic element (14), engaging over the connection section (10), and fastened on either side of it. The element is fastened via collars (16a,b). These are fastened non/positively to hoses (11a,b) or fittings, preferably via tension straps (17a,b). The securing element consists of a helical spring (14), engaging over the connection section; a helix of elastic straps...

There are sensory means that are built vertically through a altitude interceptable distance measuring system (9) via a hub system (8). The first position of the spacing to the side surface of the residual staples (1) and, beneath it, the second position of the spacing to the side surface of the main staples (3), are coverable. The evaluation and control switching (13) of the staple carriage plate ...

A water-supply valve, for example for a washing machine, has an actuator rod (600, 602) which is elevated against the downward biasing force of a spring (500, 512) by the magnetic force of a first solenoid (410, 412) generated by applying a voltage thereto. The actuator rod (600, 602) is retained at its uppermost position by attractive forces generated by a permanent magnet (700, 702) and acting o...

The present invention provides catheter apparatus (10, 200) and catheterization methodology for generating an arteriovenous fistula or a veno-venous fistula on demand between closely associated blood vessels and at a chosen anatomic site in vivo. The catheter apparatus is preferably employed in pairs, each catheter of the pair being suitable for percutaneous introduction into and extension through...

A label for containers comprises a foamed polyester film that has a density of less than 1 g/cm<3>. The foamed polyester film may be blown away in air and then floated away in water during the recycle process for containers. After separation from the containers the foamed polyester film may be reclaimed by a chemical process to recover raw materials for polyesters.; Une étiquette destinée à des ré...

A quick connector coupling for a fluid line includes a hollow female connector body (20) defining an interior radial bearing surface (56). A male member (200) has a radially enlarged upset (202) and is insertable into the connector body to a first position and withdrawable from the first position to a second position within the connector body. A retainer (100) is disposed in the connector body and...

Disclosed is an automatic travelling apparatus which permits: determination of a permissible travelling area on the basis of images taken by an image pickup device or video camera, showing the sight of the area appearing ahead of the vehicle; steering control of the vehicle to go into a target course in the permissible travelling area; and selection of a predetermined way of a selected crossing or...

The present invention relates to using lithium salts of an organic material having 2 to 30 carbon atoms and at least one carboxylic acid in a rigid polyurethane formulation to produce foams having energy absorbing properties and methods of preparing rigid polyurethane foams.

This invention deals with viscosity improvers which are obtained through the use of a mixed catalyst system comprising a tertiary organo halide and a Lewis acid catalyst.

Described is a method of producing rigid polyurethane foams from polyols and polysiocyanates plus foaming agents and, optionally, foaming auxiliaries. The method is characterized in that the foam is obtained by reacting: A) a polyol component with an average of at least three hydrogen atoms and containing 1) 60 to 100 % of polyethers and/or polyesters with at least two hydroxyl groups, a molecular...

Film made from acrylate terpolymer blends, consisting of mixtures of (A) soft terpolymers of acrylate, styrene and acrylonitrile with (B) thermoplastic polyurethanes (TPU) with Shore hardnesses of less than 90 A (DIN 53505). Also claimed is a process for the production of this film.

The method involves using a reference track image on board the train formed w.r.t. the track distance markers and determining the current distance covered on the track for correlation with the reference track image. Satellite navigation is used for the on-board position determination. When the satellite positioning becomes unavailable, e.g. in tunnels and in station halls, it is replaced by correl...
