Abstract: The invention relates to the roll seam welding of container frames wherein a first welding procedure is carried out using welding rolls (10, 11) and subsequently the welded frame is fed to a second welding procedure using welding rolls (20, 21). The welding force of the second welding procedure is adjusted in accordance with a welding parameter for welding quality that has been determined during the first welding procedure. In this manner even sheet metals that are difficult to weld can be welded with better welding quality and the welding quality can be improved.

Abstract: This invention relates to a method for producing a detachable connection between two components. The first component is elastically deformed such that a clamping surface of the deformed component corresponds to a corresponding clamping surface of the other component with predetermined play. The two components can be slotted together. After the two components have been slotted together, a pressure connection is created when the deformed component elastically reforms. The first component is elastically deformed when axial forces are exerted upon force transmission sections of the component. The axial force is converted into the desired radial deformation or movement of the clamping surface by means of joints which are provided between the force transmission sections and the clamping surface.

Abstract: In a device for temperature responsive switching of overflow fuel quantities from a diesel fuel injection pump to a fuel supply tank or a filter of a fuel supply system a switching valve, arranged between the fuel injection pump and the tank, is actuated by a bimetallic element. Parallel to the switching valve is provided a throttle for continuous air venting. A pressure control valve with a low opening pressure is installed in the connection between the switching valve and the filter. The heated overflow fuel quantities are mixed with cool fuel from the tank and therefore the danger of clogging of the filter, which could be caused by paraffin separation, is substantially reduced.

Abstract: A voltage measuring device for use with an encapsulated, high-voltage switching installation including an inner conductor within a grounded metallic outer tube. The measuring device includes means for widening the outer tube, thereby providing a space for locating certain portions of the measuring device. Positioned in the space formed by the widening means is an auxiliary electrode means, insulated from the outer tube, which forms a capacitor with the inner conductor. Measuring means and servo-indicating means are connected in various ways to the capacitor formed by the auxiliary electrode means and the inner conductor. These measuring means respond to variations in the electrical characteristics of the capacitor thus formed to thereby give an indication of the voltage of the inner conductor.

Abstract: A voltage measuring device is described which is suitable for application to encapsulated, high-voltage switching installations which include an inner conductor surrounded by a grounded metallic outer tube. The device utilizes the fact that an electric field exists between the inner conductor and metallic outer tube. It includes means for widening a portion of the outer tube to thereby form a space for locating certain portions of the measuring device. The device itself includes an electro-optical component, such as a Kerr or Pockels cell which is positioned in the space defined by the widening means, at a distance from the inner conductor which is approximately equal to the distance that the outer tube is located from said inner conductor. A metal layer is positioned on that side of the electro-optical component which is away from the inner conductor. The metal layer is electrically connected to the grounded, metallic outer tube.
