A contact pin is pressed into the terminal post unitl the rear end of the pin makes contact with the wire. Then the housing recess is filled with casting resin to fix the pin and the wire with the winding end in position.

Abstract: A control circuit for an ignition system having a magnet generator provides an abrupt adjustment of the ignition time point toward an advanced ignition when a predetermined upper speed range of an engine is reached. The control circuit includes a frequency dependent R-C member coupled to a control switching transistor activated at a preset voltage level to trigger an ignition switching power transistor. The R-C member is preadjusted so as to be charged to the preset voltage level at the time point of the transition from a lower to the upper speed range.

Abstract: A weld-on nut is welded to a metal component to form a portion of a battery grounding terminal. The weld-on nut is tinned or galvanized with an anti-corrosion metal coating. The weld-on nut is welded to the associated sheet metal component by means of an electric resistance welding operation. In order to protect the contact surface from fusion of the tinning by welding spatters, an electrode contact surface on the nut is arranged axially offset relative to an electrode abutment surface or transversely to the latter. This weld-on nut can be of extremely light and small construction. The nut also requires provision of only a relatively small centering hole in the sheet metal in the region of the welding position, whereby the sheet metal component is only very slightly weakened.

Abstract: Zeolites are prepared by hydrothermal crystallization of alkaline aqueous synthesis mixtures. Normally the zeolites are filtered and washed with water until the filtrate shows a pH of about 9 to 12. Sometimes, especially if the resulting zeolite consists of very fine particles, the zeolite filter cake shows thixotropic properties.If the filter cake is washed with diluted sodium hydroxide or only small amounts of water this thixotropy can be avoided.

Abstract: Armature reaction in a dynamo is reduced by constructing the main pole structure and/or the commutating pole structure with a plurality of iron lamina arranged parallel to the axis of rotation of the dynamo. The iron lamina are separated from each other by nonmagnetic or magnetically weak material of a predetermined thickness designed to cause a predetermined minimum but high reluctance to be offered to flux generated in the main or commutating pole structure as a result of armature current. The core of each pole may be split into a first and second core half at the root and in the direction of the axis of rotation. Each core half has a larger portion which extends to the adjacent core half of the neighboring pole, thereby forming a yoke. A smaller portion of each core half extends into the air gap between poles and, together with the corresponding portion of the core half of the neighboring pole which is similarly extended into the same air gap, forms a commutating pole.
