Abstract: 1,233,387. Automatic voltage and current control. STONE-PLATT CRAWLEY Ltd. Dec.2, 1969 [Dec.2, 1968], No.57094/68. Heading G3R. A regulator for a self-excited alternator comprises main and auxiliary thyristors controlling the field current in accordance with a parameter of the alternator output, each auxiliary thyristor being in shunt with a main thyristor and arranged to conduct at low alternator output voltages produced by residual magnetism on starting, after which the main thyristors take over when the voltage has built up. The field winding 6 is supplied from the alternator output terminals A, B, C through a tapped auto-transformer 4 and main thyristors 7a, 7b, 7c each shunted by an auxiliary thyristor 29. The firing pulses for the thyristors are generated by an oscillator 11 which commences to function at a low voltage (approximately  ¢ volt), so firing the thyristors 29 to energize the winding 6. The thyristors 29 conduct until a predetermined current (about 1 amp) is reached, whereupon the thyristors 7 take over. The oscillator 11 is controlled in dependence on the alternator output voltage, a main load current and the current applied to a battery charged by the alternator, Fig.2 (not shown). The sensing circuits comprise:- (1) a divider 14 sensing the alternator voltage for comparison with the voltage of a Zener diode 16, the error signal being applied to a transistor 17, (2) a current transformer 18 sensing the load current for comparison with the voltage of a Zener diode 21 before transmission to the transistor 17, (3) a shunt 22 sensing the charging current for comparison with a reference in a differential amplifier 12 before transmission via a transistor 23 to transistor 17. Ambient temperature compensation is provided by selection of the Zener diodes and the diode 28. An unregulated demagnetizing field winding 8 is provided to increase the excitation range. Various means are provided to reduce the decay period of the field current. In the described embodiment the field winding 6 is shunted by a series circuit of a diode and a Zener diode 30 whose breakdown voltage is slightly less than the peak of the sinusoidal supply voltage, so that the field 6 regenerates through the thyristors until this voltage is reached. The Zener diode and diode combination may be replaced by: - (1) a Zener diode in series with a capacitor or (2) a negative temperature coefficient resistance in series with a diode or (3) a series-parallel circuit comprising a capacitor, two diodes, a Zener diode and a thyristor, Fig. 3 (not shown). In another modification, Fig.4 (not shown) the field winding 6 has no shunting circuit and three identical logic circuits, each comprising a transistor, resistors, Zener diodes and a diode, are provided to supply additional firing pulses to the thyristors 7 to allow them to conduct during negative half cycles of the supply, so forcing the field current to decay. The method of operation of this additional firing circuit is described, Fig.5 (not shown).

Abstract: 1,239,654. Harpsichords. R. A. HANDS. 24 Feb., 1970 [26 Feb., 1969], No. 10237/69. Heading G5J. A plectrum for a harpsichord or a similar automatic musical instrument is rigidly fixed to a bar capable of substantial torsional strain about an axis roughly parallel with the string, but relatively rigid under bending stress, the bar being mounted for rotation about an axis approximately perpendicular to the string and to the plectrum. The triangular plectrum 15 having a horizontal face 16 is mounted on a bar 8 extending from a boss 6 on a screw 2 in the key 1. As the key is depressed, pressure of the surface 16 on the string 18 twists the bar 8 until the plectrum slips past the string to sound it. On release of the key, pressure on the sloping side 17 of the plectrum overcomes the spring 13 to slide the plectrum past the string without sounding. A stop 11 screwed into register bar 12 determines the degree of engagement of the plectrum with the string and hence the loudness of the note. The mechanism may be arranged on the opposite side of the key pivot to strike with an upward movement or may be actuated through an intermediate mechanism.
