Patent GB-2057796-A (GB)
Title: Ac transmission line reactive power compensation system
IPC: H02H9/00
Filed: 1980-08-27
Abstract: A damping arrangement for thyristor switched capacitors in reactive power compensation systems. Large inrush currents are possible where capacitors are re-connected after a time of disconnection. The invention consists of incorporating in series with the thyristor switching bank a large damping resistor bypassed by thyristors which may in fact be a series part of the main switching bank. The bypass is opened prior to closing the main thyristors and closed a short time after thus encouraging decay of transients. The re-closing of the bypass may be done in stages (sections of the damping resistor) or progressively in successive cycles.

Title: Method and system for secure transmission and reception of video information particularly for television
IPC: H04K/
Filed: 1981-02-25
Abstract: A method and a system for secure transmission and reception of a video signal wherein parts (L22, L23...; S1, S2...;) of the video signal arranged in a first predetermined sequence are delayed in relation to each other to form an encoded video signal having its parts rearranged in sequence relative to their positions in the first predetermined sequence. Rearrangement of the video signal parts is accomplished by storing successive parts of the video signal in a storage device (100) and retrieving the stored parts so that the transmitted video signal has its parts arranged in a sequence other than their normal sequence. A decoder (260) at a remote location is provided for receiving and restoring the transmitted sequence of video signal parts to its original sequence. In a television scrambling system, the parts of the video signal are fields, lines (L22, L23...) or segments of lines (S 1, S2...), and rearrangement of the sequence of video signal parts is accomplished on a line segment, line or field basis. Codes (CODE I.D.) may be transmitted to the remote location with the video signal or otherwise to indicate the manner in which the parts of the video signal have been rearranged.

Title: Atomic absorption analysis
IPC: G01N21/31
Filed: 1982-03-30
Abstract: In Zeeman atomic absorption analysis a magnetic field is generated at the location of a sample 14 or that of a light source 12 to compensate for the background absorption of a sample, which magnetic field is transverse to a light beam 10 from the source 12 directed through the sample and the intensity of the magnetic field is alternated cyclically between a maximum value and zero. Thus, cyclic Zeeman-splitting of the resonance line of a looked-for element is caused, with the absorption due to the sample at the wavelength of the original resonance line falling to half with the field on, and the background absorption remaining the same. After passage through the sample 14 and a monochromator 18, the beam 10 is applied to a photomultiplier 20 the signal from which is applied to a signal processing circuit 22 which forms the difference of the signal amplitudes at a detector 20 according to whether the magnetic field is applied or not applied. In contrast to prior art devices of this type, does not contain any polarising optical elements are not used. <IMAGE>
