Patent GB-731593-A (GB)
Title: Short-time electric switch
IPC: H01H3/26
Filed: 1951-05-04
Abstract: 731,593. Switching systems. LICENTIA PATENT-VERWALTUNGS GES. May 4, 1951. [May 4, 1950], No. 10587/51. Class 38 (4). [Also in Group XXXVII] A time controlled switching system for spot-welding machines comprises cam-operated contact springs 15, a synchronous motor 1, 2, a clutch 3 between the motor shaft and cam-shaft 7 and a clutchoperating coil 29, which is momentarily energized when the welding electrodes engage the work, to actuate members 30, 28, 26 for effecting engagement of the clutch. Engagement occurs at a definite point in the A.C. cycle. The upper contact spring 15 is normally held clear (by a catch 13) of the lower contact spring which is supported by a " switch off " lever 17 riding on a cam 8. On energizing the coil 29 a catch 27 on clutch actuating member 26 is released from one of a series of peripheral recesses in control drum 25 on a shaft 19 which, together with shaft 7 commences to rotate synchronously with the supply voltage. A timing arm 10 which is angularly adjustable on the shaft 7 engages a striker 14 as the shaft rotates and releases catch 13, thereby allowing the two contacts 15 to engage and initiate flow of welding current. The contacts open to terminate the weld when a cut-away portion of cam 8 reaches the lever 17. The shafts 7, 19 continue to rotate until the catch 27, which has meanwhile been riding on the rim of drum 25, falls into the next recess and allows the clutch actuating member 26 to return to its inoperative position and so release the clutch. Prior to de-clutching, a cam 24 on shaft 19 has operated a re-setting lever 16 which raises the upper contact spring 15 on to the latch 13. To allow for timing periods in excess of those corresponding to a single revolution of the shaft 7, the shaft 19 is capable of longitudinal move. ment and is provided with cams 20, 21 adapted to prevent dropping of the " switch-off " lever during one or two revolutions of the shaft 7. Further cams 22, 23 are arranged to prevent operation of the re-setting lever until after shaft 7 has made one or two revolutions. Drum 25, similarly, has two further series of notches which do not become effective until the shaft 7 has completed one or two revolutions.

Title: Improvements in or relating to frequency discriminator circuits for angle-modulated oscillations
IPC: H03D3/08
Filed: 1945-05-03
Abstract: 591,301. Frequency and phase modulataon. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 3, 1945, No. 11205. Convention date, May 3',' 1944. [Class ,40 (v)] In the reception of frequency - modulated and phase-modulated waves by means of a balanced frequency-discriminator, out - of - balance voltages at the discriminator output due to mis-tuning of the receiver are utilized to redress the balance. As shown in Fig. 1, the incoming .wave is converted to an intermediate frequency at the mixer 2 and is fed through an IF amplifier 8 and band-pass coupling 9 to a parallel pair of valves C, D. The anode circuits A, B of these valves are tuned respectively above and below the true IF,.,as indicated by the frequencyresponse full-line curves of Fig. 3. The voltages across the circuits A, B are fed to rectifiers F, G with load resistances 22, 23 shunted by condensers 39, 40, the cathode end of resistance 23 being earthed. The audiofrequency signal is taken off at the point J across the :resistances 22, 23, and any D.C. component present at J, due to a discrepancy between the actual IF and the true IF, is fed back through a smoothing filter 21, 24, 19 to the grid of the valve D to alter the amplification of this valve so that its. output is represented by the dotted curve B1, Fig. 3. Owing to the coupling between the valves C, D, afforded by the cathode resistor 14, the output of the valve C is altered in the opposite sense, giving the response curve A1, Fig. 3. The crossover-or balance point FC of the two curves is thus shifted to FC<1> in. the direction to redress the balance. In a modified circuit, correcting voltages of opposite sign are derived from the rectifier outputs and are applied to the grids of the valves C, D (Fig. 6, not shown). In a further modification (Fig. 7 not shown), the discriminator is of the phasing type disclosed in Specification 489,094, and each of the two channels to the rectifiers includes an amplifier and a band-pass filter, the gain of the amplifiers being automatically adjusted as in Fig. 1.
