Title: Image display system
Inventor: FYLER N F
IPC: H01J31/34
Filed: 1965-08-26
Abstract: 1,098,069. Image pick-up tubes. LITTON INDUSTRIES Inc. Aug. 26, 1965 [Aug. 26, 1964], No. 36766/65. Heading H1D. [Also in DivisionH4] A cathode-ray tube, for producing a video signal representative of an electromagnetic, ultrasonic, magnetic or electrostatic field pattern, comprises an array of conductive elements 42 extending through the tube faceplate 30, a voltage pattern indicative of the field pattern being impressed on the exterior portions 46 of the elements 42, and the interior portions 44 being scanned by an electron beam 48 to generate a video signal. The cathode-ray tube, apart from its faceplate, may be similar to an orthicon camera tube, with the wall electrode operated at 10 to 20 volts for increased sensitivity, and the return beam collected by an electron multiplier, Fig. 2 (not shown). The tube may be operated so that a positive or negative change pattern is impressed on elements 42. In the latter case the multiplier is shielded to collect only electrons whose paths have been disturbed by the charge pattern, which is not destroyed by the scanning beam. The tube may be used in an underwater ultrasonic viewing system, Fig. 1 (not shown), the reflected ultrasonic wave being focused by a liquid lens comprising a membrane filled with carbon tetrachloride on to an array of piezoelectric crystals 50. Each detector 50 is of truncated pyramid shape and is located between an embossed metal sheet 52, which provides additional focusing, and the base electrode of a corresponding transistor 54. The transistors 54 have a common emitter electrode 56 and collector electrodes 58 connected by leads 60 to the conductive elements 42 of the cathode-ray tube. The leads 60 are embedded in a ceramic block 62, a resistive layer 64 being provided between block 62 and collectors 58, and a stress yield space 66 is provided between block 62 and faceplate 30. Alternatively, leads 60 may be extensions of elements 42, or may be arranged in a flexible cable connecting the array of detectors to the tube faceplate, Fig. 6 (not shown). Also, if no amplification is required, the transistors 54 may be replaced by diodes. Equivalent circuit diagrams are given. The interstitial volume between sheet 52 and block 62 may be filled with insulating fluid to equalize the static pressure on all sides of detectors 50. The cathode-ray tube may also be used in conjunction with an array of photoconductors, photo-cells, scintillators or thermocouples for producing video signals representative of visible or invisible light, X-ray or heat fields, or may be used with probes for investigating static electric fields. The array of detectors may be one, two or three dimensional.

Title: Direct current control circuit
IPC: H02M1/06
Filed: 1972-08-11
Abstract: 1412283 Control of D.C. motors GENERAL ELECTRIC CO 11 Aug 1972 [31 Aug 1971] 37554/72 Heading H2J In a chopper circuit for controlling power from a D.C. source to a load (e.g. a motor) using a switch, an inductor circuit charges a capacitor to a value greater than the D.C. source, and reverses the charge on the capacitor to render the switch non-conducting. As shown, the power supplied from battery 10 to series motor 14, 16 in a vehicle is controlled by thyristor 20. Initially, the storage means i.e. commutating capacitor 34 charges from the battery via diode 42. Thyristor 20 is triggered on by pulse generator 48 which, after a time delay, also triggers on thyristor 32. This applies the charge on capacitor 34 as a reverse bias across thyristor 20, which thus turns off, the bias current being initially limited by saturable choke 30. With thyristor 20 off, an inductor circuit comprising inductor 18 and battery 10, reverses the charge oil capacitor 34 to a value greater than the battery voltage using the energy stored in inductor 18, to apply a reverse bias to thyristor 32 which turns off. After a further delay, from a capacitor-zener diode circuit (Fig. 3, not shown), pulse generator 48 triggers thyristor 36 on, causing a further reversal of the charge by resonance with inductor 18, reverse biasing thyristor 36 to turn it off and leaving capacitor charged in its original direction but to a value higher than source 10, ready for the cycle to be repeated. With thyristor 20 off, current through the motor armature and field is maintained by diodes 46, 44 respectively. The triggering pulses to thyristors 20, 32, of variable frequency and/or width determined by a speed controller, are obtained from unijunction relaxation oscillators (58, 60) in the pulse generator (see Fig. 2, not shown). The motor field current may be reversed by switch 26 using relays F, R and contacts F1, F2 and R1 R2 respectively. By suitable values of inductor 18 and capacitor 34, the commutating period of thyristor 20 is said to be independent of load current.

Title: Method of purifying intermetallic compounds
Inventor: HILL RONALD ALFRED
IPC: C22B9/04
Filed: 1956-12-10
Abstract: 794,966. Purifying intermetallic compounds. STANDARD TELEPHONES & CABLES, Ltd. Dec. 10, 1956, No. 37635/56. Class 82(1) An intermetallic compound is purified by heating in vacuum above its melting point for a time sufficient for all impurities having vapour pressures greater than that of the compound to vaporize, at the same time some of one of the components of the compound being vaporized also, condensing the vaporized impurities at a lower temperature under vacuum, adding to the compound sufficient of the last component to restore the stoichiometric relationship, and further heating together the compound and added component under vacuum to restore that relationship. The compound may then be zone-refined under vacuum. As an example, iridium antimonide was heated for 24 hours at a temperature of 600-700‹C., tellurium, zinc and cadmium impurities were condensed at a temperature of 100-200‹C., and antimony added to restore the stoichiometric relationship. As shown, the compound 6 in a sealed quartz tube 1 is heated by a furnace 7, the impurities condensed at 8, and the make-up component 9 is introduced from a sealed tube 2

Abstract: 1,249,741. Insulating conductors by extrusion. PHELPS DODGE COPPER PRODUCTS CORP. 28 July, 1969, No. 37844/69. Heading B5A. [Also in Division H1] A concentric layer 14 of insulating material disposed about a tubular centre conductor 11 carries a helical web 16 of insulating material which supports an outer conductor (not shown). A thin aluminium or copper tape is passed through a forming die 70 which has a passage 71 whose cross-section varies continuously from rectangular at the input end to substantially annular at the output end and wraps the tape into a tube with overlapping edges. The tube is passed over a central supporting rod to an extrusion die 38. A plasticized resinous material, e.g. polyethylene, polysulphone, P.T.F.E. is fed into the extrusion apparatus by a screw 36 and is forced into the die orifice through an annular cavity 34. The die 38 has a radial suborifice 42 intersecting a circular orifice 40 of larger diameter than the centre conductor 11. The die 38 is rotated in a carrier 44 by a motor 53, as the centre conductor 11 is pulled through the die 38 thus forming the helical web 16 and insulating layer 14. The die 38 is rotated in the same direction as the direction in which the outer edge of the centre conductor overlaps the inner edge. To produce an insulating layer of uniform thickness the speed of the conductor 11 through the apparatus 22, the speed of rotation of the die 38 and the rate of feed of the plastics insulating material are co-related by control unit (30, Fig. 3, not shown). The relationship may be varied to change the pitch of the helical web, either manually or automatically.

Abstract: 1507510 Colour television SONY CORP 16 Sept 1975 [18 Sept 1974 26 Dec 1974] 38025/75 Heading H4F In a solid state colour television camera comprising a CCD and colour filter arrangement, line interlaced scanning is effected by driving the CCD so that corresponding picture elements in odd and even fields are shifted in the vertical direction by one-half of the vertical pitch of picture elements, the colour filter being so formed that the output video signals of the odd and even fields are the same with respect to their colour signal components. A three-phase CCD with electrodes # 1 -# 1  is described with reference to Figs. 1-5 (not shown), the colour filter being as shown in Fig. 6 in which an odd field line scan height is indicated at OF and an even field line scan height at EF. For each picture element the colour filter is divided into two sections 2a 1 , 2a 1 <SP>1</SP>, the filter elements in the upper sections corresponding to alternate lines of picture elements being RGBRGB ... transmissive and Cy (cyan), Mz (magenta), Yl (yellow), Cy, Mz, Y1... transmissive, while the lower sections are white (W) light transmissive. The resulting video signal during odd lines of odd fields is shown in Fig. 8A, this being the same as during even lines of even fields, whereas the video signal during even lines of odd fields, Fig. 8B, is the same as during odd lines of even fields, i.e. the frequency spectra and phase relationship of the colour components during even fields are the same as during odd fields so that the processing thereof, Fig. 7, is identical. The composite video output signal S is fed via a low pass filter 23 and a line delay compensator 32 to a subtractor 24 the output of which is shown in Fig. 8C. This output is delayed by one line period 25 and added 27 and subtracted 26 from the composite input signal to derive (a) the output of Fig. 8D (colour components cancelled by addition) i.e. the DC component which is fed via low pass filter 28 to matrix 31, and (b) the colour components Fig. 8E which are demodulated 29 and 30 to derive R-(G+B)/2 and B-G which are fed to matrix 31. In a second embodiment a colour filter of the form shown in Fig. 9 is used with a filter that restricts R and B to a narrow band. With this filter the carrier frequency of the R light component is 1/2# 11  while that of the B light component is 1/3# 11  Figs. 10A and 10B (not shown). Further colour filters are described with reference to Figs. 11, 13 and 14 (not shown). A second CCD camera is shown in Fig. 15 in which the areas 50a, 50b are masked so that the photo-sensing areas 20a, 20b of the upper sections of the picture elements for alternate lines are staggered. The colour filter used with this CCD is shown in Fig. 16 and the processing circuit therefor is described with respect to Fig. 17 (not shown) which includes # 11/2  delay switched at line rate to bring the colour component signals from successive lines into phase.
