Filed: 1971-03-01
Abstract: 1373663 Automatic voltage control JOSEPH LUCAS (INDUSTRIES) Ltd 16 Feb 1972 [1March 1971] 5676/71 Heading G3R An electro-mechanical voltage regulator for controlling the dynamo 15 of a road vehicle having a battery 17 comprises normally-closed contacts 26 which are controlled by a voltage winding 23 to periodically connect a resistor 27 in series with the dynamo field winding 16, normally-open contacts 19 which are controlled by windings 18, 21 to close when the regulated voltage reaches a predetermined value and to open to prevent discharge of the battery 17 into the dynamo 15, and a clipper diode 29 which conducts if either the battery or dynamo is incorrectly connected, thereby limiting the voltage between the terminal 11 and the junction of members 23. 24 and reducing the value of the regulated voltage so that the contacts 19 are not closed. The diode 29 may be replaced by an ordinary diode (28), Fig. 1 (not shown),-if it is only necessary to protect against incorrect connection of the battery. The winding 21 may be connected to the other side of winding 18 without affecting the circuit operation.

Patent GB-643191-A (GB)
Title: Improvements in and relating to high frequency coupling device
IPC: H03H2/00
Filed: 1948-02-27
Abstract: 643,191. Radio frequency couplings. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 27, 1948, No. 6122. Convention date, Nov. 12, 1946. [Class 40 (v)] The primary or secondary winding of an inductive coupling device for high-frequency apparatus comprises a single loop conductor deformed towards the major axis thereof to provide a relatively narrow-shaped area between two substantially circular-shaped areas, and switching means for selectively shorting the conductor across the narrow area. The arrangement is used in connection with frequency band switching. Fig. 1 shows the invention applied to the converter stage of an ultra-high-frequency superhet receiver. Radio frequency signals are applied to the primary winding 8, the secondary winding 9 being connected to the grids of a push-pull amplifier 14. Local oscillations are applied via lead 18, and intermediate frequency signals are taken from transformer 23. The secondary winding 9 comprises two portions 9b, 9c, each of which encloses a substantial area relative to the area enclosed by the centre portion 9a. Band switching is effected by means of switch 30 which when open allows the whole of loop 9 to be utilized, and when closed effectively short-circuits the loop 9c portion. The arrangement avoids disadvantages arising from switch contact variations, or the loading effect of the short-circuited portion of the loop. An alternative switching device is described.
