Abstract: PHN. 9070.     ABSTRACT:     The invention relates to an electric lamp having a pinch seal in which a molybdenum foil is incorporated as a current leadthrough conductor.  An external current conductor is connected to the foil.          As a result of differences in coefficients of expan-sion, a capillary space is present around the exter-nal current conductor, through which space oxidizing gas can reach the molybdenum foil.  Oxidation of the foil involves an increase of its volume and results in crack of the pinch seal.         In lamps according to the invention a metal plug is provided around the external current conduc-tor, said plug being sealed to said current conductor and to  the glass of the pinch seal and sealing the capillary space in a vacuum-tight manner.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of producing alkyl silanes by reacting hydrosilanes with olefines in the presence of a carrier material containing platinum or palladium as catalyst and which is located above the reactant mixture.  The method of the invention is characterized in that the reactant mixture is kept boiling and its rising vapours are guided to a condenser while by-passing the catalyst, condensate flowing from the condenser and passing through the carrier material containing the catalyst is for example guided back into the boiling reactant mixture via a sluice.  This method enables one to improve the space-time yield and at the same time to reduce the formation of by-products.

Abstract: Abstract Digital dwell circuitry for a spark and dwell igni-tion control system is disclosed.  Maximum advance and reference sensors are utilized to produce pulse transi-tions which determine positions of maximum and minimum possible advance for spark ignition with respect to the position of the engine crankshaft.  For each maximum advance sensor pulse transition a main counter starts a sequential running count of speed independent clock pulses wherein the maximum count obtained by the counter is related to engine crankshaft speed.  The running and maximum counts of the main counter are utilized by dwell circuitry to determine the time prior to the next maximum advance pulse at which spark coil excitation should occur.  The main counter running count also determines several inputs to a read only memory (ROM) circuit whose output controls a rate multiplier.  The rate multiplier receives input clock signals, provides selective fre-quency division for these clock signals in accordance with the ROM output, and the output of the rate multi-plier is coupled to an accumulator means whose accumu-lated count is utilized to determine the occurrence of spark ignition by terminating spark coil excitation.
