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.

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.

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.

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.

A restraining system for knee protection in a motor vehicle having a safety belt system includes an element which deforms plastically upon impact of a vehicle occupant's knees. The element can be transferred by means of a servo drive from a comfortable remote-from-the-knee position into a securable, restraining close-to-the-knee position. The restraining system permits the largest degree of freedom of movement for the vehicle occupant given specific peripheral conditions or prevents the vehicle occupants slipping away towards the foot space of the vehicle. The signal for transferring the knee protection into its close-to-the-knee position in the driving mode occurs by a device triggered in the event of the non-use of a three-point safety belt system.

The invention relates to a method and to apparatus for crushing brittle material for grinding using a material bed roll mill, in which at least a proportion of the branch stream returned to the roll gap is dried to such an extent that a mixed moisture content which lies below a critical moisture content is produced in the roll gap. In this way it is possible even for material for grinding which has a high moisture content and above a critical moisture value has a tendency to sticking and/or caking on to be crushed satisfactorily.

In the illustrative embodiment of the invention as described an engine bonnet is articulated to the framework of a motor car. A gas spring is articulated to both the framework and the bonnet. The gas spring balances part of the weight of the bonnet when the bonnet is to be opened by hand. In case of an accident the framework and/or the bonnet may be crushed in longitudinal direction of the car. In such case the piston rod of the gas spring is pushed inward of the cylinder beyond the normal innermost operational position and a retaining device becomes effective so as to prevent the piston rod from returning towards its outermost operational position.

The invention relates to a method and to apparatus for the crushing of material to be comminuted by means of a material bed roll mill, in which such material is forcibly delivered in a regulable mass flow to the roll gap. In this way even materials which tend to slip on the rolls can be crushed satisfactorily. It is also possible to keep the nature of the product constant over a wide range of variations in the throughput.
