Title: Improvements in or relating to thermionic valve oscillation generators
Inventor: SPEARS RALPH AUBREY
IPC: H03B5/34
Filed: 1947-12-06
Abstract: 644,086. Valve oscillator circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Dec. 6, 1947, No. 32261. [Class 40 (vi)] A saw-tooth generator of the Miller-transition type has its frequency stabilized and can be switched to produce a sinusoidal output by the connection of a piezo-electric crystal across the Miller feed-back capacitor. The Figure shows an oscillator in which the Miller feed-back capacitor C1 is shunted by a crystal X which has a resonant frequency which is harmonically related to the repetition frequency of the sawtooth generator which is adjustable by varying capacitor C1. During the forward stroke of the sawtooth the anode voltage falls linearly in the normal manner and the crystal produces H.F. sinusoidal oscillations which are superimposed upon the saw-tooth waveform and which determine the exact point at which the fly-back stroke commences. Due to the high Q of the crystal the H.F. oscillations continue during the short fly-back period, the duration of which is determined by the time constant of the network C2, R5. The positive feed-back produced by capacitor improves the performance of the stage as a sinusoidal oscillator. In the position shown of the switch S1 a saw-tooth waveform is derived from terminal 1, the network L1, C5 filtering out the sinusoidal voltage. In the lower position of the switch, a sinusoidal waveform is derived from the terminal 2 and the saw-tooth voltage is removed by network L2, C6.

In a method of connecting one or more leads to a terminal, a punch 46 and an anvil 48 are moved to cause the anvil to wrap portions of the terminal about the punch to form upstanding ears 12 and the terminal is advanced to position the ears between dies 58, 62 to crimp the ears to the lead or leads. A strip 1 of terminals is located on a guide plate 22 and is advanced step-by-step by means of spring loaded, pivoted feed fingers 32, 34, which have tips 36 engaging in apertures (4) in the strip, Fig. 1 (not shown). The feed fingers are resiliently connected to a piston-rod 28 for reciprocation therewith and drag plates 44 prevent backward movement of the strip 1 as the fingers are withdrawn. The punch 46 and die 58 are driven downwardly by a ram (53), Fig. 4 (not shown), after an operator has placed a bared end of a lead core between the ears 12. The plate 22 is also driven downwardly by the ram against a spring (24), Fig. 6 (not shown), thereby lowering a terminal on to the anvil 48 and shearing another terminal from the carrier strip (3), Fig. 1, between the working edge of a shear blade 66 and the die 62, prior to the crimping action of the dies. As the ram (53) rises, the leading terminal, which has been crimped to the leads is removed from the die 62 by the operator and the terminal strip 1 is advanced to place the leading terminal over the die 62.
