Abstract:
A method and apparatus for depositing an underlayer and/or a magnetic thin film layer on a data storage disk are described. The sputtering power is supplied in the form of pulses during the application of the underlayer and/or magnetic storage to periodically ignite the plasma and increase the charge-carrier density in the sputtering chamber. The repetition frequency and parameters for the pulses and pauses between pulses are adjusted to achieve a desired nominal value for the coercive field strength of the magnetic layer. Preferably the repetition frequency of the power switching is from 10 to 80 kHz and the ratio of pulse length to pulse pause is within 5:1 to 1:5.
Abstract:
The invention relates to a collision-protection system for passengers of motor vehicles. In a manner which is known in principle, an airbag is automatically inflated in the event of an accident. In order to control the direction and speed of expansion, the airbag is wholly or partially encased by a tough, plastically deformable film, which is overstretched and torn open as the airbag is inflated.
Abstract:
A material for sliding surface bearings comprising a layer of a wrought copper-zinc alloy of thickness of about 0.1 to 1.5 mm inseparably joined to a backing layer of steel or stainless steel. A co-rolled joining strip of copper may be between the two layers.
Abstract:
A protection system for a competition vehicle for a competition vehicle driver has shoulder belt parts provided with one shoulder air bag respectively which can be inflated within fractions of seconds and can be emptied again in an energy consuming manner. In the inflated condition, the shoulder air bags are supported on the driver's shoulder regions and support a protective helmet from below against a lateral tilting.
Abstract:
The present invention relates to stable granules comprising active substance, granulating auxiliary, enveloping substance and if appropriate additional components, wherein the enveloping substance in each case comprisesa) silicon dioxide particles orb) homopolymers of unsaturated sulfonic acids orc) copolymers of unsaturated sulfonic acids and unsaturated carboxylic acids ord) homopolymers of (meth)acrylic acid esters ore) copolymers of (meth)acrylic acid esters and unsaturated carboxylic acids orf) mixtures of one or more of these constituents.
Abstract:
A pair of edging rolls for edging the flange edges of symmetrical steel sections, particularly I-girders. Each edging roll has a barrel engaging in the inner contour of the steel section and guiding the section, and two edging paths adjoining the barrel on either side and extending outwardly in a conical shape for the flange edges of the section. The edging paths are arranged at the outer circumference of bushings which are guided so as to be displaceable coaxially at both sides of the barrel on the roll body. The bushings have end faces which face one another and engage in annular recesses of the barrel.
Abstract:
The application relates to a mount of a front seat passenger airbag unit in the upper area of a dashboard of a motor vehicle. The mount uses a holder which consists of flat material and on the one hand can be attached to the housing of the airbag unit and on the other hand can be attached securely to the vehicle. In order to ensure a certain degree of resilience of the airbag unit during the unfolding of the bag, the holder, which is made of a flat material, is guided along below the floor area of the housing and is connected there to the latter. The holder projects beyond the housing, on both sides and is attachable securely to the vehicle at a spacing from said housing in such a way that between the lateral ends of the housing and the mounting points of the holder fixed to the vehicle at a distance from the housing. The holder forms a deformable bridge area which serves to absorb energy and during loading permits the holder to rotate in both directions about its longitudinal axis.
Abstract:
The invention relates to a wire connector for cable wires, in particular of telecommunication cables.The invention provides housing sections 2, 2' are constructed identically, and are adapted to be snap-fitted with each other after being rotated by 180 degrees relative to each other, that the crosspieces 6, 7 between the guide channels 8, 9 form the press-in sections, that the snap-fit elements are formed of the side walls 4, 5 of the housing sections 2, 2' extending parallely to the guide channels 8, 9 and that on the inner side of the longer side wall 4 is provided a receiving groove 11 for the other, shorter side wall 5 of the housing section 2, 2'.
Abstract:
The application is concerned with a cover of an airbag unit in a motor vehicle which is equipped with a tear-open line and has a foam-backed foil and the process for making the cover. The process includes:a) heating a foil in the region of the intended tear-open line;b) forming a channel in the foil which is drawn-in in relation to the adjoining face of the foil in the region of the tear-open line;c) creating a reduction in wall thickness of the foil at the tear-open line, located at a channel bottom, by high-frequency embossing;d) introducing the foil into a mold and foam backing the foil;e) producing a smaller wall thickness in the foam backing in the region of the tear-open line.
Abstract:
Salts of organic carboxylic acids can be separated from non-salt organic compounds using a semipermeable membrane consisting of a perfluorosulfonic acid polymer or a salt of such a polymer, by bringing a solution of the salts and the organic compounds in a C.sub.1 -C.sub.4 alkanol into contact with one side of the membrane and having the pure solvent on the opposite side of the membrane. The process can be used, for example, in purification processes or for recovering reactants from reaction residues.
