An electronic system includes at least two interchangeable similar components arranged for alternative operation in the system the operative one of which is continuously monitored by feeding its output signal through a network having a transfer function which is an inverse of the transfer function of the component itself, and comparing the output of this network with the input to the component, and if these signals are not similar a switching circuit disconnects the faulty unit and connects the alternative unit. Fig. 2 shows a system in which units K3 and K4 are included in a signal path and unit K5 is a spare unit which may be connected in place of one of the units K3 and K4 if one of these should develop a fault. Each of the units has a comparison unit MA1, MA2, or MA3, associated with it which compares the input signal to the unit K3 &c. with the output from that unit after it has been modified by the inverse transfer network. If the comparison determines a difference an output is fed to a logic circuit, Fig. 4 (not shown), which energizes the appropriate switching networks FF1, FF2, and FF3, to bias the diodes D1 to D10 appropriately to disconnect the faulty unit from the signal circuit and substitute the spare unit K5 in its place. The spare unit may also be continuously monitored by a test signal applied to its input and the logic circuit may have alarm circuits to indicate which of the units have developed faults.

Title: Differential or balance gear
Filed: 1919-04-12
Abstract: 144,027. Berg, K. A. T. April 12, 1919. Differential or balance gearing suitable for motor-cars and motor-ploughs comprises an epicyclic train which is operative in turning, and an arrangement of pawls for driving both wheels positively when going straight. The side elements 3, 4 of the ordinary balance train are connected by bevel planetary elements 5, 6 carried by an inner ring 2. An outer ring 1 driven from the motor carries pawls 7 connected in pairs by pivot bolts 8. The pawls 7 are adapted to engage notches 9 in the elements 3, 4 so as to drive these elements positively. In running in a curve, the outer element 3 or 4 overruns, causing its pawl 7 to rise out of the notch 9. The bolt 8 then rocks, disengaging the other pawl 7, and causing a catch 10 to be depressed so as to engage the end of a spring-pressed bolt 11, which is carried by the inner ring 2. The ring 2 is thus driven from the ring 1, and the balance gear transmits the drive. Spring-pressed bolts 12 are provided in the ring 1 adapted to engage notches 13 in the ring 2 for reversed driving The bolts 11 are then pressed inwards out of the way by inclines on the catches 10.

March 27, 1931, No. 9436. Convention date, March 29, 1930. [Class 40 (v).] In a direction-finding system of the kind wherein two cones I, II, Fig. 1, of radiated energy are utilized to give a critical indication along a line which is the locus of the point P of intersection of the cones, the radiating oscillator is continuously swung to and fro over an arc containing the focus of the reflector. Or the reflector may be swung relatively to the oscillator. As shown in Fig. 3, the relatively large reflector S is fixed, whilst the Hertzian wave or other generator E is swung through an angle alpha, so that it rests for a longer period of time at one end of its traverse than at the other. The cones of radiation originate at the two extreme positions 1, 2 of the arc of swing. The oscillator E may be backed by a small auxiliary reflector S1, Fig. 4. to concentrate the radiation more effectively on the main reflector S, whilst another screen Z masks any radiation from the oscillator during its swinging movement. In operation, a receiver exploring the line P1, P2 will respond to the characteristic signal from the cones I, II respectively at all points outside the point P of intersection of the cones.
