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 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'.
摘要:
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 contact member for electrical conductors, in particular for cable wires of telecommunication systems, comprises two electrically conductive contact sections forming a contact slot, in order to simplify and make less costly manufacture and assembly of the components including the contact members, the contact section are formed from an insulating material and are provided with metallized contact surfaces.
摘要:
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.
