Title: Improvements in and relating to negative resistance networks employing transistors
IPC: H03K3/281
Filed: 1956-02-10
Abstract: 807,924. Transistor negative impedance circuits. GENERAL ELECTRIC CO. Feb. 10, 1956 [Feb. 15, 1955], No. 4238/56. Class 40 (6). In a circuit employing two transistors 10, 11, Fig. 1, of opposite conductivity type, the collector of each is connected to the base of the other and a source of potential E is connected to the emitter of transistor 11 and through resistor R to the collector. When the emitter of transistor 10 is negative with respect to the base a small reverse current flows, Fig. 2, until the potential of the emitter is raised sufficiently for the transistor to conduct, point A, the increase in collector current causing the base potential of transistor 11 to rise so that the transistor conducts and the collector potential becomes more negative. The fall in base potential of transistor 10 causes a further increase in the emitter and collector currents to trace out the negative resistance path A-B. At point B the base potential of transistor 10 is sufficiently low that the remainder of the characteristic is traced out as the forward operation of the diode comprising the emitter and base of transistor 10. An inductor may be included in series with the resistor R to extend the frequency range of operation, Fig. 3 (not shown). By including a capacitor charged from a supply over a resistor to the input terminals of the circuit, a relaxation oscillator may be produced, Fig. 4 (not shown). The addition of an inductor in the capacitor circuit causes the arrangement to operate as a simusoidal oscillator. The wire 26 may be taken from the input to the junction of resistor R and supply E, Fig. 6 (not shown), to displace the characteristic of Fig. 2 downwards, Fig. 7 (not shown). In a further modification, Fig. 8 (not shown), a battery is arranged between the input terminals, the input then being applied over a capacitor across the resistor R and supply E. The circuit is stated to be applicable to mono- or bi-stable circuits and to improve the Q of filter networks.

Filed: 1972-01-29
Abstract: 1374000 Sewing E ERRASTI 29 Jan 1972 4264/72 Heading DIG In an ornamental stitch zig-zag sewing machine a stack of cams 10 is selectively engaged by cam followers in the form of radial fingers 49 disposed helically round a drum 47. The drum is supported at one end of a swing arm 44, 45 which is clamped to a shaft 50 at its other end. As the cam pushes the follower the arm swings back and forward, causing the shaft 50 to oscillate on its axis. Shaft 50 is fixed to a plate 52 (Fig. 4) which also oscillates. A slider 65 is held against plate 52, and carries a block 68 attached by a pin 69 to the lever 70 which moves the needle bar. Thus as the shaft 50 oscillates the needle bar is moved. To adjust the width of the stitch the lever 75 is adjusted, and to adjust the position of the field of the stitch the lever 77 is adjusted, causing the slider 65 to pivot on a pin 63 and move the spring loaded pin 56 to click along the teeth 55. A spring 60 urges the plate 52 in an anticlockwise direction, and so biases the cam follower against the cam. Different cams are selected by rotating the drum 47, connected through gears 37 and a ratchet 40 to an external knob 9. Enough back lash is provided in the gears so that neither the knob 9 nor the indicator disc 13 is oscillated when the machine is stitching.

[Also in Groups XXVI and XXIX] An alternator 13 driven by a steam turbine 11 having a regulator 24 sensitive either to speed or steam pressure (see Group XXIX) may be paralleled with a second alternator 5 driven from the Diesel propulsion engine of a ship when its speed lies within a given range. The Diesel exhaust is used to generate the steam for turbine 11. When the Diesel 1 is running but outside the speed range the turbine set supplies the ship's network 15 at a constant frequency determined by the regulator 24, which is now controlled by a centrifugal governor, the pressure sensitive part being disconnected by an electrically operated valve. When the speed is suitable and the two alternators are in parallel the valve is opened, the regulator responds to steam pressure and the speed controlling element is ineffective, the frequency depending then on the speed of the output shaft 2 of the Diesel. Auxiliary Diesel driven alternators 14 supply the network 15 when the ship is in quay, or they also may be paralleled with the turbine set. Propulsion auxiliaries, on a circuit 16, may be supplied either from the ship's network or direct from alternator 5.
