Title: Improvements in or relating to thermometer devices
Inventor: FRANKLIN ERNEST
IPC: G01K7/38
Filed: 1959-12-12
Abstract: 895,705. Measuring temperature electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 2, 1960 [Dec. 12, 1959], No. 42328/59. Class 40 (1). Apparatus for measuring temperature comprises a ferromagnetic core fed with current pulses of alternate polarity, the time for saturation of the core being indicative of its temperature. The transducer element consists of a short-circuited length of coaxial cable 7, 8 (Fig. 4) with a film 9 of magnetic material, preferably having a rectangular hysteresis loop, deposited on the inner conductor 7 adjacent the short-circuit. A generator 4 (Fig. 3) producing a pair of positive and negative pulses each of 2 microseconds duration, at a repetition rate of 1000 cps. (Fig. 6a), is connected to the transducer 5 in shunt with a resistor having the characteristic impedance of the transducer and the transmission line. The positive pulse produces a reversal of the core flux in a time tr dependent on its temperature, and is repeated during the following negative pulse, producing voltage pulses (Fig. 6b) at the input to the transducer which are amplified at 3 and integrated at 2 to give an indication of the temperature. The film 9 may comprise an alloy giving high sensitivity in the required temperature range, or may comprise layers of material having different Curie temperatures, giving more than one range of high sensitivity.

Title: Improvements relating to television camera arrangements
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/09
Filed: 1962-11-09
Abstract: 1,057,253. Colour television cameras. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 4, 1963 [Nov. 9, 1962], No. 42515/62. Heading H4F. A colour television camera comprises a first pick-up tube 5 which produces a luminance signal of relatively high resolution, at least one other pick-up tube 9, 12, 13 from which is obtained a luminance signal of relatively low resolution and means 21, 25 for subtracting from the high-resolution signal a proportion of said low-resolution signal of smaller amplitude than the high-resolution signal so as to produce an output signal in which edges transitions are emphasized. The tube 5, which produces the high-resolution luminance signal, may be an image orthicon tube and tubes 9, 12 and 13, which may be videcons, produce colour component signals. The signals are individually gamma corrected in stages 14, 15, 16 and 22, and the colour signals are combined in a matrix circuit 20 to produce the low-resolution luminance signal. The high- and low-resolution luminance signals, Figs. 3a and 3b (the lowresolution signal being shown inverted) are then subtracted in circuit 21 to produce the signal shown in Fig. 3c and a proportion of this signal as determined by the setting of a potentiometer 24 is added to the original high-resolution signal in an adder circuit 25. The final signal at terminal 26 takes the form shown in Fig. 3d. The light 1 from the scene reaches the pick-up tubes by way of a zoom lens 2 and an optical system including a mirror 3 which is of smaller diameter than the light beam issuing from lens 2. As a consequence an image of high resolution due to light from the axial zone of lens 2 is formed on tube 5, and an image of lower resolution due to light from the marginal zone of lens 2 is formed on tubes 9, 12, and 13. 6 is a transfer lens for the image formed by lens 2. 7, 8, 10 and 11 comprise a reflecting and dichroic filter system for forming component colour images on tubes 9, 12 and 13. In a first modification, Fig. 2 (not shown), tubes 9, 12 and 13 are replaced by a single vidicon camera which operates in conjunction with a striped colour filter to derive three colour component signals. In a second modification the single tube system described in Specification 714,154 may be used in place of tubes 9, 12 and 13. Reference is also made to the use of lead oxide photoconductive pick-up tubes in place of tubes 5, 9, 12 and 13. An alternative optical system may be used in which the low-resolution colour images are obtained by electron or optical difocusing.

Title: Video amplifier circuit for television receivers
IPC: H04N9/64
Filed: 1975-10-17
Abstract: 1477568 Transistor amplifiers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 17 Get 1975 [22 Nov 1974] 42747/75 Heading H3T A video amplifier for a TV receiver comprises at least two amplifiers each containing at least one semi-conductor device 4, 5, 6 fed by unstabilized voltage V1, first means 82 which samples the bias voltage of each amplifier and provides one signal representative of the bias voltages, second means 79 receiving the representative signal and generating a control signal, and third means 70, 62, 60 transmitting the control signal to the semi-conductor devices for maintaining stable operation, e.g. against variations of supply voltage, transistor characteristics, tube current or temperature. In a receiver for colour TV a negative feedback loop (not illustrated) is provided as follows. The outputs of the amplifiers taken from the collectors of 4, 5, 6 corresponding to the red, green and blue signals respectively are joined through a divider to the base of transistor 82 via resistors 87, 88, 89 at terminals R, G, B respectively. Transistor 82 functions as a threshold device and is conductive only during the flyback periods, when the voltage at the common point of 87, 88, 89 is at its maximum value. Negative feedback provided by resistors 85, 86 ensures that the supply voltage V 3  to 82 need not be stabilized. The signal produced at the collector of 82, being representative of the bias voltages of the three colour amplifiers, is applied to the base of transistor 79 which acts as a comparator gate, being turned on only by the flyback pulses applied to the input terminal of a resistor 77. The power supply at V 2  is a stabilized reference voltage. A network including a capacitor 74 stores the output of 79 as a substantially D.C. control voltage for feeding back to the emitter circuits of transistors 4, 5, 6. An amplifier 62, 60 &c. for the luminance signal Y provides an output on the same paths to the emitters of 4, 5, 6, the function of 4, 5, 6 being to add the Y signal to the R-Y, G-Y and B-Y signals respectively.

In the embodiment shown, two endless canvas or synthetic plastic covered unrolling belts 1 of a width greater than length of the roll R are supported around rollers 2, 3 and are each extended towards the other by an adjustable centre roller 4 to form the trough. The belts 1 are driven in the direction of the arrows A by driving the shafts 14, 15 of the rollers 3 from an electric motor 6 through a belt and pulley system 7, 8, 9, 11, 12, 13, 16, 17, 18, Fig. 2 (not shown). The fabric C is drawn up over an idler roller 19 and a draw-off roller 20 mounted on a frame 21 and may be plaited on to an inclined table 22. The roller 20 is driven from the shaft 14 through a belt 24 and pulleys 23, 25 through a slipping drive device at a slightly faster draw speed than that at which the fabric is freed from the roll. A second draw-off roller 20X may be used as an alternative to the roller 20 and is mounted at the opposite end of the frame 21 to be driven by the shaft 15. The empty board B automatically drops through the gap at the base of the trough.
