Patent DE-3942483-A1 (DE)
Inventor: KLEBL WOLFRAM
IPC: H01B13/00
Filed: 1989-12-22
Abstract: A method is specified for the continuous marking of electrical wires, by means of which method annular features, limited in the axial direction, are applied to the surface of the wires by means of ink jets. The ink jets emerge under pressure from at least one nozzle driven by an electrical oscillating system, whose frequency is controlled in proportion to the withdrawal rate of the wire. In order simply to change the axial distance between the features, square wave pulses are supplied to the oscillating system from a converter which converts an electrical DC voltage into a frequency, by means of which the frequency of the oscillating system is predetermined. A DC voltage, proportional to the withdrawal rate of the wire, is passed to the converter as the nominal value.

The rotational position of the armature (21) is set by means of a pulsed step by step movement of the reception unit, or the corresp. movement of the wire nozzle (30). The wire is threaded in to a slot of the armature and pulled through this. The wire is held down respectively by a holding down device at the slop inlet and outlet sides, also at an intermediate place of the slot, for pressing the wire (22) in to the slot in a stretched condition, with a predetermined winding radius, whilst maintaining the wire shape. The armature is then turned to the next slot to be wound, by a further step by step operation of the reception unit or carrying out a corresp. movement of the wiring nozzle. These steps are repeated. The wire is pulled through the corresp. slit in the soldering ring and the nozzle (30) is returned to its original position. The wire is wedged at the soldering ring and the wire is cut-off at the wiring start and end. The entire steps are then repeated for further wire windings in the armature. USE/ADVANTAGE - Winding carried out without template or flyer giving economic winding and less complicated.

Title: Effect roving -  by flocking projected in free flight into gap between spread slippers to form sandwich
Inventor: AMSLER BRUNO
IPC: D01G15/70
Filed: 1991-03-19
Abstract: To produce an effect roving, two rovings or slivers are laid continuously over each other with an intermediate layer of effect flocking material blown in between them to form a sandwich structure. Each flock is projected into the moving roving material at a higher speed than the speed of roving travel, across the roving travel line. They move across in free flight to be shaped laterally and clamped in place without distortion. The slivers or rovings are spread out laterally under tension and then deflected to form a V-shaped gap between them where they are laid over each other. The flocks are propelled by compressed air at a speed which is a multiple of the speed of roving travel. Before the flock strikes the roving material, the compressed air is deflected to one side across the direction of travel, which give a lateral shaping to the flock and projects it in free flight into the V-shaped gap between the rovings. As the flocks are accelerated in the blowing stage, they are given a twist in the direction of acceleration. ADVANTAGE - The method gives an effect roving with multi-coloured effects, such as flame colours in the material

Inventor: OTTERBEIN STEFAN DR
IPC: B60G17/018
Filed: 1991-05-11
Abstract: A system for controlling or regulating suspension movement in a vehicle comprises means for classifying the vehicle operation into three categories in which i) travel safety is principally taken into consideration in a safety mode, ii) travel comfort is principally taken into consideration in a comfort mode, and iii) a predetermined suspension setting is selected in a standard mode. Classification proceeds from detected movements between the wheels and the vehicle body, 201 such as spring stroke travel, Xar. The actual value of the wheel load fluctuations P, and the movements of the vehicle body Xag are ascertained 202 from the detected spring stroke travel and through the interrogation of certain criteria 204, 205 it is determined whether the suspension should be reset with a view to minimising the wheel load fluctuation (safety mode) 206 or with a view to minimising of body movement (comfort mode) 207 or whether the suspension should be set to the predetermined setting (standard mode), 208. <IMAGE>
