Patent GB-2085231-A (GB)
Title: Antenna system for direction finder
IPC: H01Q21/20
Filed: 1981-05-13
Abstract: Two pairs of vertical or horizontal antennas, e.g. (Vn,Vs), are arranged at the same spacing (2 l ) on straight lines which intersect at right angles. A directive output is generated from the sum or difference of the outputs of those antennas, and a sense output is generated from the difference or the sum of the outputs, whereby the direction of arrival of electric waves at the antenna system is measured. The formation of the sum and difference values is carried out, for each pair of antennas, by a respective pair of transformers (Mn,Ms) having their primary windings connected, respectively, to the outputs (Tn,Ts) of the antennas. Each transformer has first and second secondary windings, the first secondary windings of the transformers being connected in series in-phase, and the second windings being connected in series anti-phase, between respective output terminal pairs (Oa, Ob). The antenna systems do not require sense determining vertical antennas and maintain a stable phase relationship between the directive and sense outputs. The horizontal antenna system enables the arrival direction of horizontally-polarised waves to be measured. <IMAGE>

Title: Excess Voltage Arresters
IPC: H01T4/12
Filed: 1981-09-18
Abstract: An excess voltage arrester of the kind comprising a pair of electrodes defining a discharge gap housed in a hermetically sealed, gas-filled enclosure (1, 3, 5) wherein the electrodes (1 and 7) both extend between terminals for external connection of the arrester at each end of the enclosure so that the arrester can be connected in a pair of lines connected with equipment to be protected so as to form effectively part of the path constituted by the lines. By suitable choice of the dimensions and materials of its components, the arrester can be made to have a characteristic impedance similar to that of the lines and thus present only a small or negligible mismatch to the lines in its non- operated condition. The pair of lines may comprise a coaxial cable and the arrester may be so constructed with electrode 7 coaxially within tubular electrode 1 to connect directly at each end with a conventional coaxial cable socket on the cable. In a modification (Fig. 2) the inner electrode may be cranked. Graphite stripes on the reduced portion 9 of end plugs 3, 5 stabilizes the strike voltage. <IMAGE>

Title: Bonded polymeric article
Inventor: GOZLAN GILLES REMY
IPC: B29C69/00
Filed: 1983-01-28
Abstract: This invention relates to polymeric, preferably heat recoverable, articles carrying fusible or flowable electrically conductive material, and a process for making such articles. A problem with such articles is that the conductive material generally has to be inserted into the formed article on an item-by-item basis, which is costly. The present article, in contrast, can be made quickly and conveniently, and comprises a polymeric material (2, 3) that has been seam bonded through the electrically conductive material (1) so as to displace the conductive material (1) from the resulting seam (4). The article may be used for electrical applications, for example for electrical cables. <IMAGE>

Title: Circuit arrangement for regulating the power drawn by at least one load from a supply network
Inventor: DUM HERMANN
IPC: H02M5/27
Filed: 1983-08-03
Abstract: A circuit arrangement for regulating the power drawn from a supply network by at least one load 50 with linear and/or non-linear current-voltage characteristic, eg. a gas discharge tube, comprises a controlled switch 53 and a current sensor 54 in series with the load. A regulating circuit 55 is arranged between the sensor 54 and the switch 53, in which an actual value for the mean load current is formed by a mean value former 57, and the output of the mean value former 57 forms one input of the regulating circuit 55. The output of the sensor 54 determining the momentary value of the load current is connected to the input of the mean value former 57, so that a quantity corresponding to the mean value of the load current forms this one input of the regulating circuit 55, and another input of the regulating circuit 55 is a desired value directly linked in phase with the supply network. The switch 53 is controlled by a pulse width regulator 60 so that the mean load current is sinusoidal. <IMAGE>
