摘要： A composite material in rod, tube, strip, sheet or plate shape with reversible thermomechanical properties is produced by joining of at least two parts consisting of a total of at least one shape memory alloy having a two-way effect, whereby each part has a memory effect by itself. In the case of at least two shape memory alloys (1, 2) with different transition temperatures but the same mode of movement, the joining of the individual parts can take place prior to the deformation in the low temperature range necessary to inducing the two-way effect. In the case of differing types and degrees of movement of the individual parts (25, 26), their joining can first be accomplished only after the individual deformations of each part for itself in the low temperature range are accomplished regardless of how many shape memory alloys with different transition temperatures are used in the structure of the composite material.

摘要： A triggering method for a thyristor switch which has at least two thyristors wired in series and a thyristor wired in antiparallel to each of these thyristors. The thyristor switch is triggered or cut off as a function of a specifiable on-off signal. At least a single triggering of a thyristor to be switched-on takes place at the earliest if a positive anode-cathode voltage is applied to it which exceeds a specifiable switch-on voltage limiting value. The method comprises generating a trigger standby signal if the on-off signal is in the switch-on condition and, with a specifiable minimum number of thyristors to be triggered wired in series, their anode-cathode voltage is greater than the specifiable switch-on voltage limiting value. At least a single triggering of each thyristor to be switched on takes place by means of a short-duration trigger pulse only during the duration of the trigger standby signal.

摘要： In a method for clock synchronization of a signal receiver, the demodulated received signal is sampled in each of the subintervals over N time windows having in each case K subintervals (1A . . . 4C). In each case, the dispersion is calculated for the sampled values of N corresponding subintervals and the K dispersion values obtained are compared with each other. The optimum sampling time is derived from the position in time of the minimum dispersion value.

摘要： A device and process for the generation of ozone using an ozone generator having two electrodes connected across the secondary winding of a high voltage transformer, the primary winding of which is connected to a converter which supplies thereto a square wave current of variable amplitude and variable frequency. A compensation coil is connected across either the primary winding or the secondary winding of the transformer. The ozone generator includes a solid dielectric and a gas path between its two electrodes. The inductance of the compensating choke and the operating frequency of the converter are selected such that the resonance frequency of the resonant circuit formed by the ozone generator and the compensation choke lies below the operating frequency of the converter current supply in any operating condition. In this way the degree of utilization of medium voltage converters of converter-fed ozone generators is significantly increased by connecting a compensation choke (6) in parallel to the ozone generator (5) and by dimensioning it suitably.

摘要： A reactionless thermionic cathode for electronic tubes consists of a metallic or ceramic support and an alloy, preferably an intermetallic compound, containing the actual emission-promoting element, with a metal from the group comprising those of the VIIIth vertical row of the periodic table and rhenium. The preferred activation substances are platinides of the elements having a low electron work function, predominantly Ba and La. The cathode is manufactured by wet-mechanical, cataphoretic or electroplating application of the activation substance to the support or by infiltration of the porous support having a pore volume of at least 10%. High emission current densities are obtained at relatively low operating temperatures.

摘要： Analog output signals from decentralized transducers for current and voltage are sampled with timing patterns generated at a decentralized location and are transmitted to a central evaluating facility in the form of digitally encoded data streams (D.sub.UR, . . . ).For the purpose of generating data sets which are each based on one sampling of each analog output signal, such that the relative time displacement of the samplings should not exceed a predetermined value which corresponds to the maximum (.DELTA.) of the data-refresh intervals, latch commands (L) are generated at greater intervals in the central evaluating facility, following which in each case the digitized sampled value arriving next of each data stream (D.sub.UR, . . . ) is temporarily stored. After the temporary storage has taken place, in each case a "Ready" signal (B.sub.UR, . . . ) is set. The "Ready" signals (B.sub.UR, . . . ) are combined in a logical AND operation to form a "Data set ready" signal (DB) which is transferred to a computer which interrogates the temporarily stored data (Z.sub.UR, . . . ) via a databus.

摘要： The pressure wave supercharger of the internal combustion engine has a diaphragm capsule (20) for controlling the supercharge air butterfly (14). The diaphragm (21) of the diaphragm capsule is, in operation, subjected on the butterfly side to the high pressure air in the high pressure air duct (2) and on the other side to the pressure at the protrusion 27 or in the compression pocket (5), via a control pressure line (26; 28). These pressures typical of the process vary with the speed of the cell rotor and control the setting of the supercharge air flap as a function of the speed and loading condition of the engine.
