Abstract: Deep-drawn sheeting which has a metallic coating on one side and whose uncoated side must be undamaged and capable of being coated while the coated, and particularly galvanised, side should provide uniform corrosion protection has recently been required, especially by the automotive industry. Various known processes, such as spraying on the coating material, dipping the strip and removing the coating on one side, adhesively bonding or welding together two strips before dipping and subsequent separation, have not led to the desired success. The present invention seeks to achieve satisfactory uniform metallic coating of the strip being passed through, with little constructional effort and exact adjustability of the coating thickness, and proposes, in the case of a strip (B) fed above the coating medium around a guide roller (2), conveying the coating medium by means of a bucket roller (3) opposite to the strip feed direction, towards the surface of the strip (B).

Abstract: In order to achieve a higher resistance to interference with respect to alien sources of deliberate interference in the use of communication connections via short waves, certain cooperative measures are proposed which include that the stations are equipped with highly-constant quartz crystal clocks and the bursts of information to be transmitted are accompanied by a time signal with the aid of which it is possible to correct any time tolerances between the stations. With an acknowledgment signal, use is made of a frequency variation of the radio frequency in the timing of consecutive burst transmissions including the acknowledgment response. The information contained in a burst in a fault safeguarded fashion is transmitted in coded form. The code sequence for encoding the information component and the fault safeguarding component of a burst and for the frequency address which determines the transmitting and receiving frequencies is recalculated for each burst on the basis of the clock time of the quartz crystal clock and on the basis of a subscriber number.

Abstract: System of testing and sorting according to tested ranges of values of miniature electronic capacitor and resistor units 10. A planar carrier 20 with rows 26 and files 24 of openings, loaded with such units 10, is disposed in an oblique plane to retain the units 10 in place. The carrier 20 ist moved in a stepped manner past an electrical testing station 119 and past a series of sorting stations 121-126. At the testing station 119, a file of probes 90 is brought into electrical contact with one end of a set of electronic units 10 in each file 24. A metal ply 34 laminated in the carrier 20 contacts the other end of the set of electronic units 10. A bridge network 186 makes measurements by connecting to the file of probes 90 and to the metal ply 34. A receptacle 131-136 is disposed at each sorting station 121-126. As each file 24 of electronic units 10 passes the receptacles 131-136, the units 10 are selectively deposited in the receptacles 131-136, by air jets, according to tested ranges of values.

Abstract: Encoder/decoders (2) are joined in a ring by transmission links (3). Data passes over the links (3) as a carrier having two cycles per bit period. The amplitude of the carrier in any bit period is non-zero and represents the value of the bit. In each encoder/decoder (2) the carrier is recovered by a tuned circuit, the clock is recovered by dividing the carrier and the data is recovered. The same carrier is remodulated with the output data. The whole system forms an oscillatory system which sustains the carrier at a frequency which varies if the properties of the ring change. 
     The specification also describes the use of a modulated carrier in conjunction with a filter blocking frequencies below 25 MHz to give good noise immunity.
