Abstract: 1,174,162. Electronic relay-operating circuits. VUMA VYSKUMNY USTAV MECHANIZACIE. 14 April, 1967 [18 April, 1966], No. 17261/67. Heading H3P. In a circuit for operating a relay for a time dependent on the magnitude of an input voltage at 10, the relay 30 is connected across the diagonal of a bridge circuit formed by resistors 17, 25 and valves 16, 24, the input voltage at 10 being fed to the grid of one valve whilst a resistance capacitance timing circuit 22, 23 is connected to the grid of the other. As described, balancing resistors 21, 27 are initially adjusted so that the polarized relay 30 is not energized, hence contacts 41 are open and 42 are closed. The time period is initiated when the input voltage at 10 unbalances the bridge, energizing relay 30 which opens contacts 42 until capacitor 23 has charged sufficiently to rebalance the bridge, thus reversing polarized relay 30 and reclosing contacts 41, 42. This time is proportional to the input voltage at 10. Relay 30 is now released, opening contacts 41 in readiness for the next input signal. A rectifier 12 and smoothing capacitor 13 are provided to enable the system to be operated from an alternating voltage at 11. Voltage limiting Zener diodes 31, 32 are provided.

Title: Improvements relating to toy aeroplanes
IPC: A63H31/00
Filed: 1957-05-31
Abstract: 820,041. Toy aeroplanes. MULLER, W., [trading as SCHREYER & CO.]. May 31, 1957 [July 27, 1956], No. 17433/57. Class 132(3) A toy aeroplane having a plurality of propellers and intended to travel on the ground has means in the fuselage for driving the propellers and the landing wheels, means also being provided for setting the propellers in motion from the driving means one after another. As shown in Fig. 8, an electric motor 9 drives a longitudinally slidable shaft 12 on which are secured four pinions 17a-d and a disc 15. Flexible shaft drives 19a-d to the propellers have pinions 18a-d for engagement , with the pinions 17, and a worm drive 11c, d also driven by the motor 9, causes a stepby step rotation of a Maltese cross wheel 11g secured to a shaft 11h. The shaft also carries a cam 11i on which a spring-urged control lever 13b bears, the forked end 13c of the lever engaging the disc 15 on the shaft 12. With the cam and the lever in position shown, the shaft is in its extreme left-hand position, all propellers are being driven, and drive to the landing wheels through gears 23, 22 at the right-hand end of the shaft is engaged; the lever may be locked in this position. Assuming the lever to be in the deepest part of the trough 11k of the cam, the shaft is at its extreme right-hand position and no drive to the propellers or wheels takes place. Upon energizing the motor 9 by a single battery, the shaft 12 begins to be moved to the left by the lever and the pinions 17b, 18b are brought into engagement thus causing the propeller connected to the shaft 19b to rotate. Further movement to the left by the shaft causes the drives to the other propellers to be engaged in turn rotation of the flexible shaft 19d also causing the landing wheels to be driven. The end of the lever now engages a contact arm 31 and a second battery is connected in circuit to increase the speed of the motor. In Figs. 1, 3, remote steering cable 36 actuated by a hand wheel (not shown) enables the plane to be steered by a nose wheel 8, and a pilot figure 38 is spring supported so that the figure oscillates slightly when the speed of the motor increases and the plane begins to move. In a further embodiment, Figs. 6, 7 (not shown); a manually operated lever is provided for moving the longitudinally slidable shaft. Another embodiment, Fig. 2 (not shown), comprises a battery unit carried by the operator, a steering wheel and other manual controls being provided on a separate portable unit. The motor may be mains energized through a transformer, and a sound producing member may comprise a resilient strip which bears on a driven gear wheel.

Abstract: 274,088. Siemens & Halshe Akt.-Ges. July 7, 1926, [Convention date]. Repeating and amplifying systems.-In a long transmission line, the maximum frequency to be transmitted is limited by the admissible building up period of the current, which is a rapidly increasing function of the frequency, and according to the invention the amplifiers are so adjusted that this maximum frequency is equal to the maximum frequency imposed by the limiting attenuation value. Fig. 2a shows the attenuation curve a of an amplifier section and the amplifying curve /3 of the corresponding amplifier, which give rise to the residual attenuation curve of Fig. 2b. The maximum frequency is therefore fixed bv the limiting attenuation value b‹. A line comprising n sections has n-1 amplifiers, so that the residual attenuation of the whole line differs from the attenuation of one section by an amount substantially proportional to the building up period.
