Patent GB-644376-A (GB)
Title: Directive antenna systems
IPC: H01Q19/13
Filed: 1947-04-18
Abstract: 644,376. Aerials. WESTERN ELECTRIC CO., Inc. April 18, 1947, No. 10376. Convention date, April 26, 1946. [Class 40 (vii)] A wave-guide horn for use in receiving or transmitting electromagnetic waves comprises means for establishing in the horn waves of two different modes having different phase-velocities in the horn, the length of the horn being so chosen that, in travelling the length of the horn, the two waves are brought into a desired phase relationship. Fig. 1 illustrates a transmitter 1 coupled to a wave-guide radiator comprising wave-guide elements 2 and 9 having different dimensions in the H-plane. The guide 2 is so proportioned that it can support only TE10 waves while guide 9 is proportioned to carry both TE10 and TE30 waves. The field distribution in guide 2 is as shown in Fig. 2 and the distribution at the junction of the portions 2 and 9 is as shown by line 18, Fig. 3. Lines 16 and 17 show the TE10 and TE30 components in the guide 9 corresponding thereto. The length of the guide 9 is such that a relative phase-change of 180 degrees occurs between the two component waves in passing down its length. In this way a field distribution is obtained across the mouth of the guide which is substantially flat, as shown in Fig. 4, and has uniform phase. The walls of the guide 9 may be flared in both the E-plane and H-plane, Fig. 6 (not shown). In Fig. 7, in a system as described in Specification 595,893, a horn radiator is used with a paraboloidal reflector having an elliptical periphery. The horn radiator is illustrated in Fig. 8 ; the guide 26 can support TE10 waves only while horn 22 can also support TE30 waves. A dielectric window 27 is mounted across the horn near its mouth and a tuning plug 30 is provided. Fig. 11 illustrates an embodiment also similar to one described in Specification 595,893 ; in this arrangement the length between the end of the guide 26 and the radiating apertures is chosen so as to obtain the desired field distribution across these apertures.

Title: Improvements in or relating to telecommunication exchange systems
IPC: H04M15/10
Filed: 1938-04-06
Abstract: 513,285. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. April 6,1938, No. 10560. [Class 40 (iv)] The tariff for a toll call is' determined by two switches which take up positions corresponding respectively to the calling and called exchanges and control jointly a number of tariff relays. The calling and called numbers are stored in a register individual to the junction, and the apparatus shown, which controls a printer over wires a-f, is associated therewith at the end of the call by a switch CH. Relay CR energizes over wire f to ground in the printer and connects wires a-d to the wipers of sequence switch SS, which in position 1 sends a figure shift signal. Relay CR then falls back and advances SS to position 2, and in this and subsequent positions signals indicative of the date are sent to the printer. The numbers are stored on condensers in the register in the manner described in Specification 476,088, and the first three digits of the called number, that is, the exchange code, are transferred in succession by relays CA-CD to relay registers DA-DD, EA-ED, FA-FD, the operated relays of which lock in series with DE, EE, FE respectively. Relay CG energizes after each transfer, advancing SS and the sequence switch of the register. Series marking circuits are completed over contacts D, E, F of wipers 4, 3, 2 of switch CS and the latter takes up a position individual to the called exchange. Alternatively, the switch CS may be set by the first digit only. Sequence switch SS passes through position 7 in which a letter shift signal is sent to the printer. In positions 8-13, relays A-K are selectively operated over wipers of CS and send signals over wires a-e to effect printing of the name of the called exchange. Relay CJ then pulls up, a figure shift signal is sent, and the numerical digits of the called number are printed in positions 15-18 of SS under direct control of CA-CD. Similar operations now take place under the control of the calling number, switch CV being set in accordance with the exchange code, and the name of the exchange and the numerical digits being printed. A group of relays, of which only RA, RB are shown' are selectively operated according to the setting of CS and connect up one of the tariff relays in dependence on the setting of CV. A different control wiper of CV is used in the case of calls to a P.B.X., and the tariff may be modified according to the class of the calling line. The circuits of the tariff relays are arranged to provide different tariffs according to the time of day.
