Abstract: 754,269. Synchronizing systems. GARRETT CORPORATION. May 5, 1954 [May 25, 1953], No. 13095/54. Class 38 (4). A system for effecting automatic closure of a paralleling switch 19 for A.C. sources 10, 11 when the two are substantially in synchronism comprises means, such as interconnected transformers 13, 17, for applying additively to a mixer 27, such as a rectifier bridge, voltages representative of the source voltages, the mixer circuit including a low-pass filter 36, 42, whereby the amplitude of the output voltage across the filter condenser 42 increases as the frequency of source 11 approaches that of source 10. The operating coil 25 of the paralleling switch, which is connected across condenser 42, is such that it is only sufficiently energized by the filter output voltage to close the switch when the output voltage attains its peak value. The filter may be of either the resistance-capacity, or inductance-capacity type and the element 36 may be disposed in the output side of the mixer. Several arrangements are described for obtaining the two references voltages, which must normally be phase displaced from each other by 180 degrees from three phase sources.

Title: Electromagnetic radiation radiating arrangements
IPC: H01Q11/06
Filed: 1971-05-07
Abstract: 1389204 Aerials; radar PLESSEY CO Ltd 10 April 1972 [7 May 1971] 13653/71 Headings H4A and H4D In one aspect of the invention an electromagnetic radiation arrangement comprises a horn with an exciting aerial mounted therein, which includes two pairs of series connected wires arranged substantially in the form of a rhombus as shown, for example, by the pairs of wires 6, 8 and 10, 12 in Fig. 1. The wires of each pair are connected to a feeder, and in Fig. 1, this is a waveguide 2, and the wires 6, 10 are connected thereto. The horn provides ground planes on opposite sides of the common plane containing the two pairs of wire. This is shown in Fig. 2, where the horn 24 is associated with the wires 6, 8, 10, 12 and the waveguide 2. Consequently, a substantially laminar electromagnetic field is radiated, extending perpendicularly to the said common plane. In other aspects of the invention a receiving aerial, which may be of the kind described above, is connected as a matched terminating load for a transmitting aerial which is of that kind. In Fig. 2, a receiving aerial which is of the same kind as the transmitting aerial is mounted alongside it, and comprises pairs of wires 6A, 8A and 10A, 12A arranged in rhombical form, a waveguide feeder 14 to which the wires 6A, 10A are connected, and a horn 22. The transmitting aerial is connected to the receiving aerial by wires 18, 20 which extend respectively between the wires 8, 8A and 12, 12A. The horns 22, 24 provide earth planes on each side of the rhombically arranged wires, said planes being inclined with respect to the planes containing the wires. The resulting polar diagram is generally flat in elevation and generally square in plan (Figs. 4,5, not shown). As spplied to an intruder detection system, an area under surveillance is determined by the shape of said radiation diagram. Movement by an intruder therein results in Doppler frequency shifted signals being received in the horn 22. These are mixed with signals at the transmitted frequency received over the wires 18, 20 and the detected signal of Doppler frequency may be used to operate an alarm.
