  • Patent number: 9366221
    Abstract: The invention relates to a corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, said corona ignition device comprising an insulator, a center electrode, which is held in the insulator, a housing, in which the insulator is held, and coil turns, which are disposed in a cylindrical main part of the housing and are connected to the center electrode. According to an aspect of this disclosure, the housing widens on the side of the main part remote from the insulator and further coil turns are disposed there, in a wider housing part.

  • Patent number: 8572863
    Abstract: A drying method is provided through a particular arrangement of air intake- and air exhaust roofs, wherein the particular material flows are not only impacted by intake air in an alternating manner from the left and from the right, but also an accumulation of air intake roofs and air exhaust roofs is avoided, which otherwise typically occurs at the separation plane between two chute modules, rotated relative to one another by 180°, which is performed for changing the side of the air impact. This method is advantageous in particular for drying parboiled rice.

  • Publication number: 20040004426
    Abstract: The present invention therefore relates to a colour picture tube and a deflection system for a colour picture tube comprising a rectangular fluorescent screen and an in-line electron beam generator system. An in-line electron beam generator system generates a plurality of electron beams which essentially extend in a common plane and which are directed onto the fluorescent screen. For correcting an east-west inward pincushion distortion, convergence magnets are arranged in a first plane on the colour picture tube and in the deflection system of a colour picture tube, respectively, and geometry magnets are arranged in a second plane which is different from said first plane. The planes of the convergence magnets and of the geometry magnets are each oriented perpendicular to the direction of the electron beams.

  • Publication number: 20030209968
    Abstract: The invention therefore refers to a color picture tube and to a deflection system for a color picture tube having a rectangular luminescent screen and an inline electron beam generation system. An inline electron beam generation system generates a plurality of electron beams substantially extending in a common plane, said electron beams being directed towards the luminescent screen. Correction magnets are arranged on the color picture tube and in the deflection system of a color picture tube, respectively, to correct a vertical green bending in the corners of the luminescent screen. The correction magnets are arranged substantially in a plane perpendicularly to the direction of the electron beams. Within this plane, the correction magnets are arranged at an angle to the common plane in which the electron beams extend which is between 20° and 70°.

  • Patent number: 6621203
    Abstract: The present invention relates to a deflection unit for mounting on an in-line type cathode ray tube comprising a coil body including grooves for receiving wound coil wires, the grooves extending substantially in a straight line. The groove extension of at least one groove is changed at at least one location such that the coil wires received in the groove become curved in the area of the changed groove extension. In a preferred embodiment the grooves are separated from each other by groove walls which in the area of the changed groove extension comprise a thickening and optionally a bulge. The coil wires wound onto the coil body form the horizontal coil or the vertical coil. The arrangement serves the selective fine adjustment of the deflection fields for eliminating convergence, coma and/or geometry errors.

  • Patent number: 5027097
    Abstract: A coil-carrier half (11) for a saddle-coil arrangement for a cathode ray tube accomodates a saddle-coil winding, in a front groove (13), a rear groove (14), left slots (18.11-18.51) and right slots. Prolongation of the left slots in comparison with the right slots results from the presence. in a rear wall (15.h) of a front-groove, at the positions where the left slots open out into the groove, of steps which are greater towards the front than at the fan-out positions of the right slots.In an asymmetrically built coil-carrier half of this sort, turns (12)' are introduced in each slot so that they run towards the prolongation position of the slot. This produces a saddle-coil arrangement which leads to fewer image defects than when a conventional saddle-coil arrangement with symmetrical coil-carrier halves is used.
