Abstract: An energy saving electronic control circuit for fluorescent tubes, where it controls the tubes' light output. This system uses a half-bridge topology, which is supplied from an AC to DC current source obtained from the mains supply. The switching transistors are driven at rather high frequencies. An inductor is connected in series with a capacitor, forming an LC circuit, which is connected to the junction between the switching transistors and these resonant at the same switching frequency of the transistors. At least one tube is connected across one capacitor, in other words in series with the inductor at one end and at the center junction of a passive half-bridge formed by two capacitors in series.

Abstract: 1437671 APC systems; pulse modulation circuits THOMSON-CSF 14 May 1974 [14 May 1973] 21396/74 Headings H3A and H4L An automatic frequency and phase control system suitable for synchronizing a plurality of TV camera assemblies to a central station comprises at the central station 1, a phase and frequency comparator 7 fed by signals received from an oscillator 6 at a remote station and from a reference generator 5 for producing a first yes-no type of phase difference signal and a second yes-no type of frequency difference signal representing also the above phase difference signal, a circuit 8 for transmitting periodically the difference signals at a certain carrier frequency and a correcting circuit 10-15 at the remote station responsive to the received signals to apply a correction signal to the oscillator 6, the sign of which is determined by the value of the frequency or phase error signal received and having an amplitude which differs according to whether the received signal differs or not from the preceding one. At the central station, the frequency and phase comparators produce respective binary outputs the first one or both of which are sampled, encoded and transmitted as a phase shift modulation or a carrier along a cable 4. At the remote station, the received signals are demodulated, decoded and separated into clock and data signals. The clock pulses corresponding to the transmitted carrier are applied via a pulse width modulator 10 to an inverter 12 which depending on the sign of the binary error data pulses applied to it enable the selected one of current sources 13, 14 to charge or discharge a capacitor 15 for a period determined by the clock pulse duration. When the frequency difference is large, the detected error signal has only one sign and only one current source is effective. The error signal changes in sign when locking is reached. A sequence detector 11 detects this change of sign to reduce the pulse width and also of amplitude of pulses delivered by modulator 10. The capacitor 15 is then alternately charged or discharged in small increments until the system settles down to a synchronized state. Fig. 2 (not shown) relates to the sequence detector 11 and includes a pair of cascaded shift register stages and combination logic gates. Fig. 4 (not shown) relates to a combined frequency and phase comparator. A pulse width modulator (see Fig. 3) comprises an amplitude comparator 30, an RC circuit 38, 35 having a large time constant and applying a steady voltage U 0 to a terminal of the comparator in the absence of any input pulses to shunt FET 37, a second RC circuit 31, 32 periodically discharged by clock pulses applied to shunt FET 34. The comparator output produces a change of state when capacitor 31 is discharged by the clock pulses and a further change of state when the charge voltage exceeds the steady voltage at the other input. The output pulse width is altered by applying pulses to FET 37 to change the charge voltage held by capacitor 35.

Filed: 1982-02-16
Abstract: A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle.

Abstract: A broken bolt extractor comprises a right-hand threaded shaft having a left-hand drill bit at its lower end, the bit superposed by a collet-spreading inclined surface. The shaft has an invertible collet threaded thereon. The collet tapers toward its lower end and carries thereon exterior left-hand threads and is longitudinally split and expandable. The upper end of the collet carries a drive head structured when the collet is inverted on the shaft to center the drilling as it engages the sides of an aligned opening in a mating flange.
