Title: Improvements in or relating to Vapor Generators
IPC: F22B1/18
Filed: 1966-09-28
Abstract: 1,157,251. Steam generators. GULF GENERAL ATOMIC Inc. 28 Sept., 1966 [1 Oct., 1965], No. 43362/66. Heading F4A. [Also in Division G6] A steam generator 41 contained within the concrete surround 11 of a helium cooled reactor core 15 (see Division G4-G6) comprises within a perforated cylindrical wall 53, a plurality of fluid conducting tubes 51 forming an economizer-evaporator section. The tubes 51 which are each in the form of a frusfco-oonical helix are nested together in a concentric stacked relationship with adjacent tubes being staggered radially (Fig. 7, not shown) to form tube bundles, supported by frusto-conical baffles 55 extending inwardly from the wall 53. Feed water, from header 57 is supplied to the outer ends of the tubes forming the bundles, and steam is collected from their inner ends through a similar header (61, Fig. 8, not shown). This steam is subsequently heated in a superheater section comprising a plurality of U- tubes 69 which are supported by annular plates 71 extending from the baffles 55, and are connected between inlet and outlet chambers 75, 77 in header 73. The U- tubes 69 are arranged in groups disposed in an annulus, around the axis of the frusto-conical tubes 51, tubes of adjacent groups being radially staggered (Fig. 6, not shown) to permit closer spacing. Ho t  helium from the core 15 passes through duct 43 to the central space within the perforated casing 53, and then passes out radially over the superheater tubes 69, and the economizerevaporator tubes 51, through the perforations 54 to be circulated back to the reactor core 15 by helium circulators 45. In a modification, Fig. 9, the U tubes 169 forming superheater, and reheater sections, are not located within the frusto-conically disposed tube bundles of the economizer-evaporator section 140, but are located above it extending downwardly from an upper header 171. The helium flow in this case is from the reactor core 115, radially inwardly over the superheater/reheater U- tubes 169, then downwardly through a conductor 182, to the steam generating section 140 and radially outwardly over the frusto-conically disposed tube bundles of the economizerevaporator section, to helium circulators 145 to be recycled through the reactor core. Two or more of these steam generators may be associated with a single reactor core.

Title: Metal film electrical components
Inventor: WAGGENER HERBERT ATKIN
IPC: H01C17/00
Filed: 1965-10-19
Abstract: <PICT:1120638/C6-C7/1> An electrical component (e.g. a resistor) has a thin film of tantalum, a tantalum compound or niobium or a substrate, a layer of aluminium oxide or silicon oxide over the film and a layer of tantalum oxide or niobium oxide over the aluminium oxide or silicon oxide.  A tantalum conductive film 12, arranged with terminals 13 or its ends to form a resistance element, may have aluminium deposited on it and anodized to form a layer of aluminium oxide 15.  Tantalum oxide formed during anodizing migrates to the top of the aluminium oxide layer 16 and forms a separate layer 16. Adjustment of the resistance value by oxidization of the tantalum is thus possible without the oxidization products being able to react with the tantalum and cause resistance drift.  Silicon oxide or aluminium oxide directly deposited by reactive sputtering may take the place of oxidized aluminium and the tantalum may be oxidized by a first anodizing prior to deposition of the aluminium, then the tantalum pentoxide formed be induced to migrate by a second anodizing.  Tantalum may be deposited by sputtering on to glass in an argon atmosphere and aluminium-plated by vacuum evaporation then be grease-masked and anodized in a solution of ammonium pentaborate in ethylene glycol and have nickel-chromium-gold terminals applied to it by vacuum evaporation.  Alternatively tantalum nitride may be deposited by sputtering with a tantalum cathode in nitrogen, and may be anodized in a citric acid solution before deposition of the aluminium.  The complete resistors are thermally pre-aged.  A component made in this way may form part of an integrated circuit.

Title: Recording and reproducing system for colour video signal
IPC: H04N5/78
Filed: 1970-09-16
Abstract: 1326078 Colour television SONY CORP 16 Sept 1970 [26 Jan 1970] 44240/70 Heading H4F An arrangement for reducing degradation of colour video information recorded magnetically as a luminance signal frequency-modulated on to a carrier and a chrominance signal frequencyconverted to a band below this luminancemodulated carrier, and read off and reconverted back to a standard (e.g. NTSC) signal comprises means for producing a signal at a harmonic of the carrier frequency of the chrominance signal as recorded and adding it with suitable phase to the luminance signal. This addition may be either before conversion and recording or after playback and separation. Fig. 1 shows the separation of luminance (Y) and chrominance C(fs) NTSC signals by filters 2 and 6, the chrominance signal being frequency-changed from 3À58 to 1À06 MHz by an oscillator 15 controlled by the colour-burst signal. This new chrominance signal is passed via low-pass filter 8 for addition at 5 to the new luminance signal obtained by frequency-modulating an oscillator in 3 and having a range from 3À5 MHz (sync.) to 6À5 MHz (white level). Circuit 41 generates the second harmonic of the new chrominance signal and this is then added to the luminance signal from 2 with appropriate phase and amplitude to minimize beat interference. Although the second harmonic has been found most troublesome due to the tape recording characteristics, it is stated that a signal at the fundamental frequency (1À06 MHz), or another harmonic may alternatively be employed. Fig. 5 (not shown) illustrates an alternative arrangement in which the compensatory chrominance harmonic is added after reconversion to a luminance component forming part of an NTSC video signal. Specification 1,326,079 is referred to.

Figs. 3 and 4 are a plan and side elevation of a vehicle housing a downwardly dicharging jet propulsion engine 12, compressed air from which is fed through branches 13 to trunks 14. Pipes 141, 142 telescopically engage trunks 14, and end in nozzles 15. The pipes 141, 142 are extended by gas pressure in the trunks, and are retracted by hand-operated winches 18 and cables 181, 182. During retraction, pipes 141, 142 may be rotated so that the nozzles occupy the positions shown at 151. Pitch and roll moments are applied by differential variation of the nozzle areas. In another embodiment, the pipes 141, 142 are connected to the trunks 14 by rotary joints enabling the pipes to be rotated about vertical axes between their operative and stowed positions by chain and sprocket gear. Fixed laterally discharging variable area yaw control nozzles may be mounted on the trunks. Fig. 8 shows a vehicle having a single forward pipe 141 and a single rear pipe 142 each mounted on a single trunk by a rotary joint 283 in the place of symmetry of the vehicle. The pipes are retractable by rotation on joint 283 by hand operated chain and sprocket gear to the positions shown in broken lines. Pitch control is by differential variation in the areas of nozzles 15. The nozzles are rotatable about the axes parallel to the longitudinal axis of the vehicle, being rotated in the same direction for roll control, and in opposite directions for yaw control.

Abstract: 447,834. Projecting colour films. 1. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Nov. 26, 1934, No. 33968. Convention date, Nov. 25, 1933. [Classes 97 (i) and 98 (ii)] In the projection of lenticular colour record images, the projection filter E is placed at such a distance in front of the objective G, for example beyond the focal point F, that the latter forms a real image of the filter behind the film C, the lenticles of which face the objective, at a distance a corresponding to that of the. filter or its virtual image during taking. In place of a filter consisting of a single set of colour strips, one having the sequence of strips repeated completely or incompletely may be used. If the images on the film are laterally reversed a mirror or reversal prism may be interposed between the objective and the filter or between the filter and the screen. In the latter case the sequence of colour strips may be reversed and the filter and mirror or prism may be united in a structure attached to the objective or the housing of the projection apparatus. A device may be provided to retain the mirror and filter vertical when the apparatus is inclined. The Specification as open to inspection under Sect. 91 describes also a form of structure comprising a sleeve fitting onto the objective, a repetition filter carried by the sleeve and a mirror inclined at 45‹ also carried by the sleeve.

In order that all the rectifier bridges 17 to 20 in an H.V.D.C. generating installation may continue to share the load and maintain the rated high direct voltage output, though with decreased available power, at bus-bars 31, 32, in the event of failure of one of the alternators 1 to 4, the converter transformers 9 to 12 are provided with tertiary windings 21-24 connected via circuit breakers 25 to 28 (which afford short circuit protection) to a common medium voltage bus-bar 29. Thus if alternator 1 for example, fails, the transformer 9 will be energized from the other alternators via the tertiary bus-bar and will continue to feed rectifier bridge 17. The coupling of the alternators through the tertiary bus-bar permits all the alternators to be run synchronously and since the secondaries are alternately delta and star connected as shown, while the tertiaries are all star, a 12 pulse voltage form on the D.C. voltage side is ensured. The bus-bar 29 may be sectionalized by circuit breakers.

Abstract: 989,115. Radiation detection systems. E.K. COLE Ltd. Nov. 28, 1963 [Nov. 30, 1962], No. 45277/62. Heading G1A. Apparatus for determining the distribution of scintillations in a scintillator comprises a plurality of photomultiplier tubes viewing overlapping areas of the scintillator, means deriving pulses from the tubes with an amplitude a function of the position of a scintillation relative to the tubes and means selecting pulses in a preset amplitude range to give an indication of the scintillations occuring within a predetermined area of the scintillator. Seven photomultiplier tubes 1 to 7, Fig. 1, view a scintillator 8. The outputs of tubes 2, 3 and 7 are compared with the outputs of tubes 1, 5 and 6 in an amplifier 17 to give a signal indicative of the X coordinates of the scintillation, and the outputs of the tubes 1 and 2 are compared with the outputs of the tubes 6 and 7 to give a signal indicative of the Y coordinate of the scintillation. These signals are respectively compared with preset signals in comparators 19A, 19B, the resultant pulse being fed to a fixed lower level discriminator 22 and an adjustable upper level discriminator 21, and an anticoincidence circuit 23 gives an output when the pulse falls within the amplitude band set by the discriminators. When the circuits 23 associated with both X and Y coordinate signals give an output, indicating that the scintillation lies in a preset region of the scintillator, a pulse is fed to counter 25. The total scintillation pulse height is derived from the output of all the tubes,fed to a discriminator 15 and a delay device 16 and used in a circuit 20 to gate the output of comparators 19A, 19B so that only scintillations due to photoelectric recoil from a gamma ray of predetermined energy are investigated. The circuit may be duplicated to permit more than one region of the scintillator to be investigated simultaneously, and the outputs may be displayed on a visual indicator such as a storage tube.
