Title: Improvements in automatic tuning of radio transmitters
IPC: H03J7/22
Filed: 1944-06-02
Abstract: 582,585. Wireless transmitters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 2, 1944, No. 10668. Convention date, March 29, 1943. [Class 40 (v)] [Also in Groups XXXV and XXXVI] Tuning; current.-Reactance means in one or more stages of a radio transmitter are operated by a motor connected to means comparing the phase of the input and output of the stage. Fig. 1 shows motors 15, 17 operating respectively a capacitor in the anode circuit of a power amplifier 1 and a loading inductor 5 in the antenna circuit. A motor 19 may adjust the coupling transformer 3 to maintain a desired anode current in the amplifier. The phase detectors 21, 25 are connected through amplifiers 23, 29 to their respective motors 15, 17. In order that mistuning of the antenna circuit may not incapacitate control of motor 17, this motor may be connected initially by switch 35 to the power supply until sufficient voltage appears across capacitor 27 to operate a relay winding 41 through rectifier 39 and restore the switch 35 to the position shown. A voltage across resistance 43, representative of the anode current of amplifier 1, is balanced against an adjustable potential drop in a resistor 47 and the difference applied to an amplifier 49, which drives the motor 19. A suitable phase detector (21, 25) is shown in Fig. 2. A condenser' 75 shifts the phase of one input 90 degrees and a phase inverter 69 applies a proportion of this phase-displaced input across a centre-tapped inductor 61. When the other input is applied between this tapping and the junction of two resistances 63, any displacement from phase coincidence or opposition produces through rectifier 57 or 59 a voltage across the resistances poled according to the sense of the displacement. The Specification describes an arrangement wherein all stages of a transmitter are automatically controlled in succession by a single motor and phase detector, electromagnetic clutches between this motor and the element operated being energized in turn by a selector switch coupled to a further switch selecting the required phase detector or current comparison unit. These switches may be operated by a magnet controlled by a relay responsive to the completion of each tuning or coupling adjustment, to render the adjustment of the transmitter fully automatic.

Title: Improved method of preventing injurious earthing currents in electrical nets
IPC: H02H9/08
Filed: 1920-04-17
Abstract: 141,756. Akt.-Ges. Brown, Boveri, et Cie. April 17, 1919, [Convention date]. Protective arrangements.-In electric supply systems having capacity asymmetrically distributed over the different phases of the system, injurious earthing currents are prevented by connecting the earthing lead to the " capacity gravity point " of the system. To obtain this point for a three-phase system, a voltage diagram C1, C2, C3, Fig. 2, is drawn and masses are assumed at the angles proportionate to the part capacities of the phases. The centre of gravity S of this mass system gives the earthing point, and as shown applied to the main transformer p, q, r, Fig. 1, may be outside the windings thereof, suitable transformer windings being provided for the connexion. An induction coil D is connected in the lead and a voltage may be imposed thereon by a second auxiliary transformer. The two auxiliary transformers may be replaced by one. The inductance of the earthing coil and the superposed voltage are arranged to allow a slight amount of earthing current, to avoid possible resonance effects that might occur if they were arranged to balance exactly such current.
