Title: Improvements in antenna systems
IPC: H01Q19/13
Filed: 1945-07-20
Abstract: 595,893. Wave-guides ; aerials. WESTERN ELECTRIC CO., Inc. July 20, 1945, No. 18704. Convention date, July 26, 1944. [Class 40 (v)] An antenna system for the transmission and reception of an approximately spherical wave front comprising a resonant chamber having a pair of spaced rectangular apertures and a wave-guide connected to the chamber between the apertures is characterised in that the longer transverse dimension of each aperture is greater than the transverse dimension of the guide. In Figs. 1 and 4, a resonant chamber 20 is formed in a head 12 comprising brass plates 13, 14, 15, rubber gasket 16, dielectric window 17 and a brass plate 18 in which are formed radiating apertures 21, 22. A tuning plug 25 is provided. The head 12 is mounted on a rectangular wave-guide 7 which passes through the apex of a paraboloidal reflector 2 having a circular aperture, to a radar transceiver 6, the apertures 21, 22 being at the focus of the reflector. The long dimension of the apertures 21, 22 is made longer than the long transverse dimension of the guide 7 being about 1.3 wavelengths, while the width of the apertures is about 0.1 wavelength. This produces a substantially spherical wavefront which combines with reflector 2 to give a point beam. Alternatively, a fan beam may be produced by using a reflector 49 with an elliptic aperture, Fig. 21. Further improvement can be secured by the use of wedges 56, 57 which serve to increase the effective reflecting surface of the sides of the wave-guide 7 and also isolate apertures 21, 22 from each other. Specification 588,159 is referred to.

Title: Improvements in and relating to apparatus for the supply of electrical energy to varying loads
IPC: G05F1/24
Filed: 1935-07-04
Abstract: 461,004. Modifying reactance characteristics ; transformer arrangements. BLUMLEIN, A. D. July 4, 1935, No. 19170. [Classes 38 (ii) and 38 (iv)] When two loads are supplied from an A.C. source with internal impedance so that variation of the current in one of the loads would affect the voltage across the other load, this effect is prevented by interposing an impedance between each load and the source, the impedances being so proportioned and coupled that the mutual impedances between them is substantially equal to the effective internal impedance of the source. In the arrangement shown in Fig. 1, the two loads L 1, L2 are each supplied through the parts S1, S2 of a close coupled autotransformer from the source A, the impedance of which is represented by Z; an impedance is bridged across part of the autotransformer. In a modification, Fig. 3 (not shown), two loads are supplied through a choke, the two parts of which are tightly coupled. These two loads and a third load are supplied from the source through a further similar choke tightly. In a modification, Fig. 4 (not shown), the choke D is shunted by a resistance R2 to neutralize the effect of resistance as well as reactance in the source. In Fig. 5, which shows one phase of a polyphase system, the primary P of a transformer supplies two load secondaries F, G connected through the two coupled parts of autotransformer t to the star points p1, p2 of the lines l1, l2. A bridging impedance z may be coupled to the transformer t. In a modification, Fig. 6, in which a load lead l1 is tapped through a transformer t, from a main H, the left part of the choke N is associated with the tapped load and the right part through a transformer t with the main load lead K. A threephase star connected generator 3, Fig. 7, supplies outgoing feeders 1, 2 through tapped chokes 4, 5, 6. A delta connected arrangement is also shown.
