Title: Improvements relating to semiconductor signal mixing and frequency converter networks
IPC: H02M3/338
Filed: 1956-04-24
Abstract: 814,817. Transistor frequency-changing circuits. GENERAL ELECTRIC CO. April 24, 1956 [April 29, 1955], No. 12525/56. Class 40 (6). A frequency changer or mixer circuit comprises a double base diode in which a signal of a first frequency is applied between the base electrodes and a second signal between the auxiliary electrode and one base electrode. Fig. 1 shows a mixing circuit using a double base diode 10 of the type described in Specifications 786,876, 787,578, which consists of a bar 12 of semiconducting material such as N-type silicon or germanium having base electrodes 13, 14 and a rectifying junction 11 which consists of an indium dot fused to a portion of the bar. A first signal source 15 is applied between the junction 11 and base electrode 14 and a second signal source 20 is applied between the base electrodes 13, 14. An output signal comprising the sum and difference frequencies is generated across an output transformer 23 and may be rectified in a conventional detector circuit comprising diode 24 and network 25, 26, 27. Instead of biasing the junction 11 forwardly as shown, the junction may be biased in a reverse direction. In the frequency changer circuit shown in Fig. 2 the non-linear characteristic of the double base diode 10 is used as a frequency changer and its negative impedance charac. teristic is used to generate one of the component oscillations. Capacitor 33 charges through the back resistance of junction 11 until the P region of junction 11 becomes positive with respect to at least a portion of the N region and holes are injected into the base portion near contact 14. This allows the capacitor to discharge through the forward resistance of the junction so that oscillations are developed. A second signal of different frequency from generator 30 is applied between the base electrodes 13, 14 and the sum and difference frequencies obtained from the mixed signal are derived across the load resistance 31. By reversing the polarities of the biasing potential an N-P junction may be used.

Abstract: 1327872 X-ray apparatus COMPAGNIE GENERALE DE RADIOLOGIE 30 April 1971 [30 April 1970] 12536/71 Heading H5R An X-ray tube in a housing 24 is mounted at the upper end of a longitudinally extendable column 6 which is rotatable about a horizontal shaft at its lower end, simultaneous rotation and extension of the column during operation being controlled by a pair of electric motors and an electronic analogue circuit, such that the motion of the X-ray source is maintained substantially rectilinear. As described, the arrangement is employed in tomographic apparatus having a cassette carriage 26 movable along rails longitudinally of a table surface 2. The column 6 is rotated by a motor 11, worm 10, and gear 9, a potentiometer 12 supplying a signal indicative of the inclination of the column to the analogue circuit, while extension of the column is effected by a motor 15, worm and gear 18 and 19, and chain and gear 16 and 21, the chain being secured to a finger 17 integral with an upper movable portion of the column, a second potentiometer providing a signal indicative of the column extension. Correlated movement of the X-ray tube and the cassette carriage 26 is produced by the rod 31, which is engaged in a slide 32 which pivots about a shaft in the carriage 26, and in a slide 30 which pivots about a shaft 29 the vertical position of which is adjustable in the. member 28 to permit radiography of a chosen plane in the object under examination. Circuitry for producing the desired relationship between the operation of the two motors 11 and 15 is described in outline (Figs. 3 and 4, not shown).

A safety device as claimed in the parent Specification is positioned in the supply pipe 11 common to a plurality of burners 10, 25, and a timing valve 44 also controls the device or an additional cutoff valve for one of the burners through its thermallysensitive ignition device. Gas at 11, Fig. 1, passes a combined diaphragm cut-off and regulating valve 16 to a stove burner 25 and an oven burner 10. If either of the pilot ignition burners 27, 35 fails, bimetals 28, 36 open valves 29, 37, allowing inlet gas at 22 to act via 17 on top of the diaphragm 13 and close the valve. The ignition devices will not ignite the burners unless a timing device 42 has closed a valve 44 since the normally open valve 44 allows inlet gas at 22 to pass via pipes 47, 48 and 17 to the top of the diaphragm 13 to close it on seat 31.
