Abstract: PCT No. PCT/SE79/00204 Sec. 371 Date Jun. 13, 1980 Sec. 102(e) Date May 30, 1980 PCT Filed Oct. 12, 1979 PCT Pub. No. WO80/00903 PCT Pub. Date May 1, 1980.A method and an apparatus for phase synchronization in a synchronous data transmission system, which transmits a binary pulse train from a transmitter to a receiver by means of an amplitude-modulated carrier. The modulation is of the so-called single-side band type (SSBAM) and the modulating signal which has been derived from the input data flow consists of superimposed pulses of so-called Partial-Response Class 4 type. The receiver clock generator consists of a digital phase-locked loop (TK, FD) controlled by level crossovers in the baseband signal, in which there is arranged between the phase detector (FD) and the oscillator (TK) a sorting circuit (SD), which sorts out and passes through to the oscillator (TK) only such information related to detected level crossovers of a predetermined first category. Further, carrier regeneration is provided by a second phase-locked loop (CR) in series with a phase correction circuit (FK). The phase correction is initiated from the sorting circuit (SD) for level crossovers of a predetermined second category.

Abstract: The invention refers to a device for sensing and indication of a predetermined fluid level in a bottle, especially during refilling of a container for condensed gas under pressure. The purpose of the invention is to enable refilling to a predetermined level, which has earlier not been possible due to the heavy turbulence which arises as a result of boiling the condensed gas during refilling. According to the invention, this goal is achieved through the sensor device (7) being set up in the bottle at a level which corresponds to the predetermined level for the fluid, at which the sensor device (7) is connected with an external indicator device outside of the tank and is set up to emit a signal to this when the predetermined fluid level is reached, as well as that a protective casing (6,10) is arranged around the sensor device (7) in order to reduce the effects of the sensor device (7) resulting in wave motion in the fluid surface.<IMAGE>

Abstract: A method of rectification of the alternating current through creating a gradient of the ratio between mobilities of electrons and holes in a semiconductor by means of a temperature gradient. The temperature gradient and the bipolar conductivity are created through self heating of the material of the semiconductor with the rectified current with simultaneous cooling of a part of the material of the semiconductor, the value of the exponent //c of the temperature (T) dependence of the relationship (b) between the mobilities of the electrons and holes in the semiconductor (b T<s//c>s) being equal to no less than 0.1. The method is implemented with a device comprising a semiconductor working element (2) with non-rectifying contacts (3 and 4) and a cooler (5) adjoining to the working element (2). The dimensions of the semiconductor working element (2) are so chosen as to ensure together with the cooler (4), within the range of working currents, a non-uniform self heating by the rectified current, the gradient of the relationship between the mobilities of the electrons and holes (db/dx) being equal to no less than 0.2 cm<s-1>s and to further ensure the bipolar conductivity of the working element (2).
