Abstract: An arrangement for the welding of cables by means of an ultrasonic welding device with a compression chamber for housing the cables defined by at least sections of a sonotrode transmitting ultrasonic vibrations, a counter electrode and lateral defining elements. In order to guarantee a desired layout for the cables, the components are installed in an insertion space, before closing the compression chamber, the width of which is less than that of the open compression chamber.

Abstract: A device for compacting and/or welding electric conductors (10), in particular for producing via nodes or end nodes of stranded conductors. The device includes a first electrode, one section of which constitutes a first delimitation surface of a compacting chamber that receives the conductor, the chamber in addition being delimited by one section of a counter-electrode that forms a second delimitation surface and by at least one additional third delimitation surface that is formed by a section of a delimitation element. The inventions simplifies the construction of the device, enabling repeated compacting and welding of conductors. To achieve this, a compacting chamber has a substantially triangular open cross-section, which is surrounded by the sections of the first electrode and the counter-electrode, these sections being adjustable in relation to one another, and by the delimitation element.

Abstract: A method and device for making multiple connections between electrical conductors surrounded by external insulators in overlapping flexible cables by ultrasonic welding. Overlapping conductors to be connected are arranged on a surface of a carrier disposed between a sonotrode and an electrode, the sonotrode and electrode are sequentially aligned the with overlapping points to be welded, and the conductors are ultrasonically welded at each of the overlapping points. The carrier either includes the electrode at least in designated areas, or includes penetrations constructed and arranged to receive an electrode in designated areas.

Abstract: The invention relates to a method and device for connecting the electrical conductors which are surrounded by outer insulation and associated with overlapping flat conductors (47, 49) by means of a sonotrode (52) producing ultrasonic vibrations and a counter electrode associated therewith. The conductors which are to be connected are to be arranged on a surface (48) of a carrier (50) extending between the sonotrode and the counter electrode. The carrier can be embodied as a counter electrode.

Abstract: (S)-Hydroxynitrile lyases which have an improved substrate acceptance and which are derived from the Hevea brasiliensis and Manihot esculenta (S)-hydroxynitrile lyases, wherein one or more bulky amino acid residues within the hydrophobic channel leading to the active center have been replaced with less bulky amino acid residues.

Abstract: The invention relates to a process for welding electric conductors employing ultrasound following compaction. The process comprises compaction of the conductors in a compaction area by adjusting height and width up to a preset contact force and ultrasonically welding according to predetermined, stored parameters.

Abstract: The invention relates to a device for compacting and then welding electric conductors, especially for making through or terminal connections of flexes by means of ultrasound in a compression chamber adapted to the conductor and adjustable for height and width, in which the conductors to be welded are first compacted and then welded. The compression chamber is adjustable to a predetermined height-width ratio regardless of the cross section of the conductors to be welded.

Abstract: For a reliable closing of the electric circuit between the inner and outer part of a contact rail on an electric warp stop, a contact drop wire with a chamfered drop wire head is provided, wherein the inner edge of the drop wire head that faces the contact rail slot of the drop wire has at least two sections which are differently chamfered.

Abstract: The contact clamp having a plurality of slots for the contact bars comprises a cover designed as circuit board. It includes at its inner side a plurality of conductors which respectively connect a metallic disk located at the other end of the conductor which pin belongs to a multiple contact plug located on the top of the casing. Two metallic disks located laterally adjacent are allocated to one contact bar including two conductor bars and elastically supported contact pins urged against the conductor bars contact mentioned disks. The separate electrical circuit for every contact bar formed by respective two conductors allows a connection of every contact bar to an individual indicating device.

Abstract: The contact bar comprises an outer bar having a U-shaped cross-section and a plurality of bar portions located therein and separated therefrom by an insulating layer. The bar portions are insulated against each other by intermediate insulating layers in partition planes extending laterally as well as parallel to the longitudinal edge. The bar portions are produced suitably by a punching out of a bar such that they, when fitted into each other, will supplement themselves again to a bar such that a shorter bar portion cut proceeding from the upper longitudinal edge of a longer bar portion fits into the longer bar portion. The longer bar portion is at the side facing the end of the contact bar, at which only the connecting contact for a power source is located is considerably narrower than at the opposite side where the drop wires will contact the bar portion upon a yarn breakage.

Abstract: One of the bars of a contact bar, preferably the inner bar (12) has an electrical resistance which increases linearly along its entire length and which can be scanned as measurable value at any desired point along said bar. A preferable embodiment for this purpose is a metallic conductive spiral (11) which is wound onto a body of insulating material (10). An inner bar (12) configured in such a manner is held in an outer bar (13), the upper part of which is of U-shaped cross section, whereby a layer of insulating material (14) separates said inner bar from said outer bar of U-shaped cross section. The metallic conductive spiral (11) has, compared to a solid bar, a substantially higher electrical resistance which is suited for the purpose of method of measurements according to the principle of the electrical resistance bridge in order to localize a dropped drop wire on the contact bar in the event of a warp end breakage.

Abstract: In the illustrated embodiments, a pair of primary X-ray diaphragm plates have cooperating front edges each with angled sections forming a generally V-shaped edge configuration and providing an included aperture angle facing the symmetry axis, of from 50.degree. to 150.degree., the angled sections being connected by a definitely rounded central section for conforming to rounded boundary contours of different organs such as the heart. The diaphragm plates are advantageously oppositely inclined and crossed so as to be capable of assuming a symmetrical overlapping relation in defining small diaphragm apertures. Further the diaphragm plate front edges may exhibit progressively reduced absorption values to provide a penumbra effect about the freely transmitted cone of rays particularly so as to facilitate examination of marginal zones of an organ which is surrounded by regions of greatly reduced absorption value.
