Title: Viewing and measuring system for remote thermal energy sources
IPC: H04N5/33
Filed: 1971-09-10
Abstract: 1357147 Infra-red viewing E C MURRAY F D ORLOFF and M I RIDER [trading as GRUBSTAKERS] 10 Sept 1971 [18 Sept 1970] 42413/71 Heading H4F To enable a user to simultaneously view a scene and the distribution of infra-red radiation of a predetermined wavelength range within a portion of that scene, a section of the optical field of view is subjected to an optical raster scan by an infra-red detector to produce a video signal which is applied to a cathode-ray tube to give the infra-red distribution display, which display is projected into the line of sight of the user for correct superposition on the viewed real scene. Colour contrast between the optical and cathoderay tube images is obtained by red filter 16 and blue dichroic mirror 92. The infra-red field is horizontally scanned with respect to a slit element 36 by an oscillating mirror 22 controlled by variable speed motor 28 and reciprocating drive 26 and providing a horizontal scan indicating signal from transducer 64. A 4Á filter 20 can be introduced into the path to the mirror to reduce noise if desired. A standard speed of 20 scans/sec. back and forth is normally used. The vertical section of the field passing through slit 36 is vertically scanned by a liquid nitrogen cooled cryogenic, In.Ar infra-red detector 44, through a rotating prism 38, the beam of infrared being laterally deflected by refraction of two parallel faces of the prism. The speed of rotation and number of facets of the prism is such that 1600 scans/sec. take place so that each field is scanned by 80 vertical lines. A light source 72, slit 76 and mirror 74 direct a beam of light on to one face of the prism so that when the beam has been reflected to be detected by means 80 and 82, respective "ON" and "OFF" pulses are generated for application to the vertical scan circuits 60 of the display tube 58. In one mode of operation, all infra-red signals below a predetermined threshold are rejected and all those above this threshold are displayed at 58 with an intensity. Hand controls 51 and 52 control the gain and mode and threshold. The threshold is indicative of a temperature and the threshold control causes rotation of a temperature marked scale 94 such that the desired temperature can be illuminated at 96 and projected 100/102 into the field of view of the user. The rotation of the prism 38 causes distortion of the scanned image and compensating distortion of the vertical tube scan deflection signal is used to obtain an undistorted display. According to the mode selected, hotter areas of the field can appear lighter or darker.

Heading G6C. In a boiling water reactor the core is immersed in coolant-moderator water and is supported in a container of thermal insulation within a concrete pressure vessel. The container is spaced from the inner walls of the vessel. Cold water enters the space and flows through passages in the thermal insulation into the coolant moderator. The water pressure in the space between the vessel and the insulation is above that of the reactor coolant to maintain the inward flow of cool water. Sintered aluminium may be used for the thermal insulation.

Title: Trimmer capacitors
IPC: H01G/
Filed: 1974-10-03
Abstract: 1459279 Variable capacitors STETTNER & CO 3 Oct 1974 [9 Nov 1973] 42953/74 Heading HIM In a ceramic disc of the trimmer capacitor, so as to minimize stray capacitance between one stator electrode and the conductive shaft, stator 1 has a circular recess co-axial with shaft 3 and the stator electrode, carried on the annular rim so formed, is as remote as possible from shaft 3 and is separated from it by an air space. The rim may be divided by grooves into semi-annular portions, one of which carries the stator electrode. The shaft may be supported in the stator by a ring 5 of low dielectric constant material e.g. p.t.f.e. which in addition to reducing stray capacitance, reduces play between shaft and stator for a more uniform response. Mechanical connection between the shaft and rotor 2 is by means of a knurled portion 3a which is a force fit and therefore locks with p.t.f.e. sleeve 4. Stray capacitance associated with the rotor is also minimized in that the electrical connection between shafts 3 and the rotor electrode 2a in a groove in rotor 2 is by a connecting strip 6 instead of direct soldering. Further, the rotor may have ceramic material removed to form recesses 2b (Fig. 6) which may extend through the rotor, or even extend to the periphery to form slots (Fig. 7, not shown). The shaft may be constructed so that a plurality of trimmers can be ganged (Fig. 20, not shown). In modifications, the stator may carry two semi-annular stator electrodes to provide a differential capacitor, or one in which no electrical connection is made to the rotor electrode.

Title: Improvements in or relating to pulse code communication
IPC: H04L25/49
Filed: 1961-12-05
Abstract: 1,008,387. Telegraphy. WESTERN ELECTRIC CO. Dec. 5, 1961 [Dec. 19, 1960], No. 43436/61. Heading H4P. An apparatus for transmitting a train of pulses and spaces comprises arrangements for generating a binary pulse train and for responding to each pulse in the binary train to transmit consecutive pulses in the transmitted train as pulses of opposite polarity when the corresponding binary pulses are separated by an odd number of time slots containing spaces and as pulses of like polarity when the binary pulses are separated by an even number (including zero) of time slots containing spaces. All the spaces in the binary pulse train are transmitted as spaces. By means of such an apparatus a binary-coded pulse train is converted into a pseudoternary form which is so arranged that the power spectrum of the pulse train is shaped in a desired manner. By shaping the power spectrum, bandwidth conservation may be brought about, so that the available communication frequency band may be used for several purposes. Information to be communicated is converted to a binary code (unit 12, Fig. 1) and is then passed to a pseudo-ternary encoder 20 before transmission. This unit is shown in Fig. 2, where pulses A (Fig. 3) from unit 24 are those from the binary encoder. These are passed to an inhibit gate 28 to which timing pulses B are applied. The gate transmits these in the absence of an A pulse to give pulses C which are delayed by one time slot in unit 29 to give the pulse series D, which operates the bi-stable circuit 40. This has two outputs E, F which are fed to operate AND gates 42 and 44, where they are gated with the A pulses. According to the condition of the bi-stable circuit the output is obtained at G or H. This output is fed to the polarity conversion circuit 50, giving an output each pulse of which has a polarity depending upon whether the number of time slots containing spaces between it and the preceding pulse is odd or even. A more complex arrangement (Fig. 5, not shown), wherein the array of time slots is broken up into successive groups, and equivalent contents of each group are transmitted along separate channels through separate pseudo-ternary subcoders, is described. Specification 706,687 is referred to.

A gas circulator unit, e.g. an electric-motordriven centrifugal blower 1, can be removed from the wall of a pressure vessel, e. g. a nuclear reactor 5, after the circulator unit has been isolated from the interior of the pressure vessel by closure of ports 5, 7 and 8. The latter are closed by sliding an inner sleeve 3 axially towards the left as by an electrical or hydraulic mechanism, to cause an enlarged diameter portion 3a of the sleeve to engage and move a cylinder 9 to a position limited by stops 9a located in slots 9b. In this position the cylinder 9 closes ports 5 and 8, and the port 7 is closed by a fixed cylinder 4. Stops 9b located in slots 3b provide the necessary abutments between the sleeve 3 and cylinder 9 when returning the latter to the position shown.
