Filed: 1965-11-30
Abstract: 1,092,040. Television. GENERAL PRECISION Inc. Nov. 30, 1965 [Dec. 23, 1964], No. 50849/65. Heading H4F. In an information storage and display system a first video signal representative of a form of fixed data, e.g. background information, and a second video signal representative of a form of variable data, which may be annotated or updated, are mixed and applied to a television monitor to produce a composite picture of the two forms of data. The fixed data may be contained on a microfilm frame (chip) or strip of frames, or on a film strip and may be viewed by a microtelevisor. The variable data which may be viewed by a television camera, e.g. vidicon, may be contained on a transparent or translucent plate (chip) larger than the microfilm so that it may be annotated or otherwise varied by means of a pen or pencil for example. Instead of viewing all the fixed data a selected part may be viewed by the microtelevisor, its degree of magnification being related to the size of the selected part viewed and displayed. Selection of the variable data is preferably a function of the fixed data selected and the part viewed and the factor of magnification. The variable data may have a fixed magnification factor related to the chip size (which is a common size) and the size of the display screen on which the composite image is displayed. By grid sectioning the fixed data chip a particular part may be selected for the field of view of the microtelevisor, the magnification by the microtelevisor of the fixed data actually displayed being inversely related to the size of the field viewed. A variable data chip is associated with each individual possible view of the fixed data chip and preferably the number of variable data chips provided per fixed data chip is equal to the number of sections formed by the grid plus one. Alternatively, one variable data chip may be associated with each fixed data chip since the variable data chip is annotatable. The Specification includes a control arrangement for positioning the microtelevisor and adjusting the magnification level of the microtelevisor with and without an auto-stop magnification level adjustment, Figs. 5 and 6 (not shown).

Abstract: 1,013,755. Radiation detectors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 30, 1963 [Jan. 16,1963], No. 51229/63. Drawings to Specification. Heading G1A. A #- and γ-radiation detector feeds two circuits having different time constants, having their outputs connected in opposition, whereby a change of radiation received can operate an indicating device. The device is useful in areas where there is considerable background radiation. The radiation is detected by Geiger tubes whose output pulses are fed to a transistor amplifier and limiter from which 40 Ásec constant level pulses are produced. These are used to trigger a flip-flop which produces 300 Ásec pulses which are fed in parallel to two time constant circuits one having a time constant of 1. 5 sees and the other of 7.7 secs. The difference between these outputs is fed to a galvanometer having a contact operated when a suitable deflection is registered to sound an alarm and light a lamp. The galvanometer is shunted by a rectifier so that it responds only to increases in radiation. The Geiger tubes are mounted on the verticals of a gantry whose horizontal member carries the circuitry and under which walks the person to be tested for radiation.

Abstract: 1,071,780. Forced flow steam boilers. BALDWIN - LIMA - HAMILTON CORPORATION. Dec. 31, 1963, No. 51364/63. Heading F4A. A steam generator heated by a heat transfer liquid such as molten sodium comprises a shell containing an annular bank of nested U-tubes whereof the inner limbs are straight whilst the outer limbs are arranged in flat involute rows connected by inner and outer return bends. In the form shown the generator comprises a cylindrical upright shell- 20 having sodium inlets 22 and an outlet 25 in the lower head 24, the upper end of the shell being closed by a tube plate consisting of ring-like plates 27, 40 respectively carrying a steam manifold 36 and water manifold 46, the plates 27, 40 being vertically separated by an extension 39. An upward extension from the plate 40 is blanked off by a rupture disc 56 which fractures if tube leakage should occur to protect the heat exchanger assembly whilst a cylindrical, doublewalled baffle 65, 66 extends downwardly into the shell from the inner edge of the plate 27 to divide the shell into inner and outer chambers 67, 68. A cylindrical bundle of straight downcomer tubes extends from the water manifold 46 to near the base of the shell where the tubes are bent to form involute rows 76 terminating adjacent the shell wall in bends 77 which, with corresponding inner bends, lead to further involute rows filling the chamber 68 to just below the level of the sodium inlets 22. Straight riser tubes 91 carry the superheated steam from the uppermost involute rows to the manifold 36 which is provided with steam outlet connections 37. In operation after the molten sodium entering at 22 has filled the shell to a level 113 in the outer chamber 68 and 114 in the inner chamber 67 the passage of the sodium is wholly over the involute rows of tubes to the outlet 25, the sodium in the inner chamber being stagnant. The baffle 65, 66 prevents the downcomer tubes 71 from being heated so that no steam is generated before the water enters the lowermost involute rows 76. The tube bank is hung from the tube plates 27, 40 whilst the outer bends 77 are spaced apart by ring plates carrying rollers so that the bank is free to expand and contract independently of the shell.

Abstract: 1307690 Storing crops A O SMITH HARVESTURE PRODUCTS Inc 3 Nov 1970 [3 Nov 1969] 52300/70 Heading A1F [Also in Divisions G3 and H1] Inert gas is admitted to an enclosed storage chamber automatically in dependence on the difference between chamber pressure and ambient pressure. In Fig. 1, perishable material such as silage is stored in a cylinder 1 leaving a headspace 6. When required, material withdrawn by augers 8 and 10 is discharged through an outlet 11. Fall in pressure within the cylinder, which would encourage ingress of air to cause spoilage, is detected through a conduit 22 by an adjustable mechanical or photo-electric pressure-operated switch 20 which operates at a predetermined pressure differential to start a generator 16 supplying inert or oxygen-depleted gas to the cylinder through a conduit 17. A relay timing arrangement is provided so that, when started, the generator operates for a predetermined period after which, if the pressure has risen to a predetermined higher value to operate a switch 21, the gas generator is stopped. Fall in pressure may also be partly countered by the effect of a bag 12 the interior of which communicates with atmosphere so that it swells and increases the pressure within the cylinder. Extreme rise or fall of cylinder pressure is prevented by the opening of a relief valve 15. If the material is removed by a rotary cutter, the pressure may be detected at the base of the cylinder and the gas supplied at the top. In a modification, a number of gas generators may be started in succession if the cylinder pressure continues to fall.

Title: Colour expansion circuit for a colour television system

Filed: 1970-11-04
Abstract: 1283910 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Nov 1970 [7 Nov 1969] 52473/70 Heading H4F In a colour expansion circuit for a colour television system the colour difference signals are quadrature modulated at 23 on to a subcarrier and the modulated subcarrier is passed through a phase multiplier circuit and through a gate 55 which only passes the part of the spectrum of interest, and is then demodulated at 91 to produce colour-expanded signals, e.g. red in the original signal has been shifted towards magenta and yellow has been shifted towards green and blue; the circuit may be used for expanding skin colourings in medicine or to explosive colour changes in chemistry. In the phase multiplifier circuit the modulated subcarrier is passed to a limiter circuit 39 which removes the amplitude modulation and then to a frequency tripler 45 which thus has a constant amplitude output having three times the phase modulation of the input. The output from frequency tripler 45 is added to the output from the modulator 23 in mixer 35 to produce an output having four times the frequency and four times the phase modulation of the input and this is passed via gate 55 to the demodulator 91 fed from the subcarrier generator 29 via a frequency quadrupler 99 and phase shifter 105, the latter being used to change the demodulation axes and hence the colours of the reproduced picture. The gate 55 is opened by the output from an AND circuit 59 fed from two polarity selection circuits 63, 65 which each has an output only when the input is of a desired polarity. The inputs to the circuits 63, 65 are derived from the colour difference signals in a sector limiter matrix 67 where the colour difference signals are added in two different fixed ratios determined by the limits of the sector of interest for application to circuits 63, 65. These limits preferably enclose an angle of not more than 90 degrees and may be at phase angles of 90 and 180 degrees to the blue colour difference signal in which case matrix 67 is unnecessary. The phase shifter 105 may alternatively be included between the subcarrier generator 29 and modulator 23 or the generator 29 may be dispensed with if an indexing display tube is used; the frequency of the output may be changed before demodulation. The saturation of the reproduced colours may be altered to correspond with the saturation of the original colours by including an elliptic amplifier (Fig. 6, not shown) in the circuit or by use of an amplitude modulator (141, Fig. 5, not shown) fed from a phase demodulator (131) fed from the constant amplitude output from amplitude limiter 39. The phase multiplication factor may, for example, be changed to two or six.
