    摘要: The invention relates to a method for producing a longlife, resistant spark plug for internal combustion engines. The electrode (16), according to the invention, of the spark plug is assembled from a plurality of initial parts: an initial part for a corrosion-resistant shell (31'), an initial part for a core (33') of high thermal conductivity, and an initial part for an erosion-resistant region (32'). These initial parts are jointly impact-extruded to form an electrode blank which is formed into the center electrode (16) by machining its head (51) and its region on the combustion-chamber side. Electrodes which are especially highly stressed are given a fourth initial part, which is also to be impact-extruded, consists of highly erosion-resistant material and is still arranged on the combustion-chamber side in front of the erosion-resistant region (32'). The electrode (16) can be used as a center electrode (16), but can also be used, if necessary, as an earth electrode after an embossing and bending process.

    摘要: To manufacture a vibration-resistant, shock-resistant electrical connection on a ceramic substrate (11) having an electrically conductive layer (12) applied to a surface (13, 19) thereof, a groove or channel-like depression (16, 20) is formed in the surface, preferably also including a through-bore (18), into which a conductor (17) is placed. The space between the conductor and the groove, the through-bore, if provided, and an extending groove at the other surface (19) of the substrate is filled with a sinterable mass (21), preferably a cermet, containing a metal which is compatible with the metal of the conductor wire (17), both for example containing platinum. As a starting material, the plate with the grooves therein is extrusion-pressed, pre-sintered at a low temperature to give it form stability, then the electrode (12) is applied, then the electrical conductor (17) and the cermet is applied and then the entire sub-assembly is fired to sintering temperature, e.g. about 1500.degree. C.; if desired, a further protective coating (22) of magnesium spinel may be plasma-sprayed on. Due to shrinkage of the ceramic components, the wire (17) will be securely held in position in the groove, and the cermet additionally forming an electrical connection between the wire and the substrate (11). For additional strain relief, the groove can be undulating (FIG. 3).

    摘要: The present invention relates to a method for producing 1-hydroxymethyl-1,2-diphenyloxiranes from 2,3-diphenylpropenals by means of epoxidation and reduction. The formation of objectionable by-products can be suppressed in that the reduction is started before the 2,3-5 diphenylpropenal is completely converted. The hydroxymethyl diphenyloxiranes represent valuable intermediate products for producing 1-azolylmethyl-1,2-diphenyloxiranes, wherein the latter can be easily produced from said intermediate products by introducing the azolyl group.
