Abstract: A clamping device for attaching crochet needles to the needle bar of a galloon crochet machine or Raschel loom. The clamping device consists of two body pieces, a lower piece and a clamping lid, which are fastened together by means of clamps. In one embodiment the body piece holds the needle shafts, a spacer inserted into each interval between needles, and a support piece between the shafts of a needle and a receptacle in the lower piece. This results in the formation of needle beds. In the other embodiment very shallow grooves are milled opposite one another in both body pieces. These are only a fraction of half the height of the needle shafts, leaving the major part of the needle shaft's height free after clamping.

Abstract: The invention relates to a control unit which comprises one or more switches and is capable of integration into a trim component installed inside the passenger compartment of a motor vehicle. The control unit is designed in such a manner that, after fitting the trim which accommodates it, a baseplate can be fixed to the trim, the baseplate accommodating the bases of all the control elements intended for the control unit.

Abstract: A low overall height is provided in a wiper-arm assembly with a wiper arm which has a fastening part, a link part which is swivelably linked to the fastening part and two side walls and a back connecting the two side walls, and a contact pressure spring which is accommodated in the link part and acts on the link part and the fastening part, and also with a wiper blade linked to the wiper arm, which blade lies at least partly in line with the link part. The low height is achieved by making the clearance between the contact pressure spring and the one side wall of the link part greater than the width of the wiper blade in the area of the link part and by the wiper blade being swivelable into the link part alongside the contact pressure spring.

Abstract: A windshield wiper installation for motor vehicles, in which wiper arms together with wiper blades which are driven from an electric motor by way of linkage members and wiper shafts, are disposed in the parked position thereof inside of a well in the cowl of the body in front of the windshield; the driving members for the wiper arms are thereby so constructed that the wiper arms together with the wiper blades are manually movable out of their parking position in the wiping direction through a predetermined angular path and subsequently are movable back into the parked position.

Abstract: A belting with a single-layer central portion and two tubular edge portions is made on a needle ribbon weaving machine with one of the tubular edge portions woven as a single layer and then closed to form the tubular edge portion by exerting a pull on the weft thread; a knitting course maintains the tubular edge portion closed along its joint by means of a tuck thread and/or an interlocking thread which is buried in the fabric by feeding a greater length of tuck thread in the knitting course than usual or by laying in the interlocking thread into the head of the knitting needle from vertically above the knitting needle.

Abstract: A woven belting has a single-ply central portion and tubular edges which are integrally woven with the central portion as a hollow plain weave; high abrasion resistance is achieved for the tubular edges by shrinking their warp threads to a predetermined extent before the weaving operation. The warp threads in the edges of the belting are subsequently shrunk to their full possible extent during a final heat setting treatment of the whole belting.

Abstract: Belting for safety belts, particularly for vehicles, having at least one side margin comprising an externally rounded protective profiled element, this element preferably being in the form of a tube. The belting, including said elements, may be woven in one piece. The warp threads in the woven tubular element preferably have a higher coefficient of elongation at break than those of the belt portion, so that under load they will not break before the warp threads of the belt portion. In order to achieve this, the warp threads of the woven tubular element may be shrunk before weaving.

Abstract: A semiconductor charge storage and detection device is provided in which an ion implanted conductive channel is buried between source and drain regions in the bulk of a semiconductor substrate. A charge storage region extends between the channel and the surface of the semiconductor device. The charge storage region is isolated from the semiconductor substrate and may be depleted of charge or enabled to store charge depending upon the electrical potential applied to a gate electrode at the surface of the device. The amount of charge stored may be detected by sensing the conductance of the buried channel. The device may be variously configured, e.g. as a non-destructive readable photosensor or as a memory cell.

Abstract: A two-phase semiconductor charge transfer device is constructed using electrodes which include both a highly resistive region and a highly conductive region. An array of such electrodes is overlayed on an insulating layer which has been deposited onto a semiconductor substrate. Alternate phases of an applied two-phase voltage source are applied to alternate electrodes in the array, thereby generating an electrical potential distribution in the semiconductor. Charge, in the form of minority carriers in the semiconductor, is stored in the minima of the potential distribution. When the voltage phases are pulsed, the potential in the regions beneath the highly conductive parts of the electrodes almost instantaneously changes value. However, in the regions beneath the highly resistive parts of the electrodes, the potential changes value much more slowly. As the potential varies, charge is transferred from the region under one electrode to the region under an adjacent electrode.
