Abstract: 849,178. Handling materials in radioactive environment. UNITED KINGDOM ATOMIC ENERGY AUTHORITY, and HOBSON Ltd., H. M. Dec. 23, 1958, No. 41534/58. Class 39(4). Apparatus for the production of a large number of isotopes by subjecting individual chemical samples, each in a container to treatment in a reactor comprises a magazine consisting of a control head 100, a plug section 101 fitted into the reactor biological shield 114, and a honeycomb assembly 102 surrounded by an aluminium thimble 104. The honeycomb assembly 102 houses the isotope containers during irradiation and comprises a column of ten identical cylindrical carriers 1 separated from each by bulkheads 2. Each carrier 1 has seven container storage cells 4 closed at one end by perforated resilient members 11 and an open-ended cell 12 forming a container transport route the carriers being mounted for rotation on graphite bearings 5 projecting from the bulkheads 2. A rotatable and axially-movable control rod 6 having a handle 58 carries a series of pairs of dogs 14 adapted to coact with slotted dogs 15 on the carriers 1. The dogs 14, 15 are relatively staggered so that the shaft 6 may be clutched selectively to an individual carrier 1 to rotate the same according to the amount by which it is axially moved. Normally, the rod 6 is in its innermost position and the cells 12 are in alignment with each other and with a fixed transport tube 16 in the plug section 101. A locking bar 17 having a series of projections 18 engaging longitudinal grooves 19 in the carriers 1 holds the latter against unwanted rotation, the bar being moved axially in conjunction with the rod 6, Figs. 7, 9 (not shown), to simultaneously unlock that particular carrier which is selected for rotation by the rod 6. The unlocking is accomplished by a circumferential groove 20 formed in each carrier and into which the corresponding projection 18 may enter, the distances between the grooves and projections being relatively staggered in correspondence with that of the dogs 14, 15. In use, the selected cell 4 to be loaded or unloaded is rotated into alignment with the tube 16 and the isotope container is moved in the appropriate direction between the cell and a position, Fig. 10 (not shown), in the section 101 by carbon dioxide gas controlled by a selector valve 116. In the blow in position of valve 116 gas is supplied to pipe 43 to propel the container into the cell 4 whereas in the blow out position the gas is supplied through pipe 44 into a space 107 surrounding the assembly 102 to propel the container into the section 101. A valve 117 controls a further supply of carbon dioxide gas for cooling the containers undergoing irradiation Loading and unloading ports for the containers are provided in the front face of the section 101, Figs. 7, 12 (not shown).

Patent GB-935540-A (GB)
Title: Improvements in or relating to apparatus for facsimile transmission
IPC: H04N1/00
Filed: 1959-12-28
Abstract: 935,540. Facsimile transmitters. R. HELL. Dec. 28, 1959 [Jan. 3, 1959], No. 44035/59. Class 40 (3). [Also in Group XL (c)] In a facsimile transmitter in which transmission is effected by the switching-on and switching-off of a carrier frequency, the carrier is always gated in the same phase position. The arrangement is such that the carrier is gated in its first passage through zero, and that it comprises at least one full period even in the case of the shortest picture signals to be transmitted. In the arrangement shown, the picture 2 on the rotating drum 1 is scanned by a beam from a source 3 and a photo-cell 6, the output of which is passed by an amplifier 7 and inverter 8 to a flip-flop device 9 which is arranged to be triggered by voltage of a predetermined value derived from black or white portions of the picture 2. Then change-over of the flip-flop 9 operates " OR " gate device 11 which triggers a multivibrator operating at the desired carrier frequency. The output of the multivibrator is differentiated at 15 and applied to a tuned filter 17 which passes the fundamental multivibrator frequency to a gate 19 and line 20. The output of the flip-flop 9 also passes via connection 21 and a differentiator 22 to a switching device 24. producing a voltage pulse for a time duration equal to the period of the multivibrator so that the latter is made operative and the gate 19 held open for a complete carrier frequency period in response to the voltage produced by the shortest picture signal. When the voltage on the line 10 ceases, " OR " gate 11 closes, bringing the multivibrator 13 to rest and effectively shutting the gate 19 so that transmission to the line 20 is immediately discontinued.

Patent GB-441217-A (GB)
Abstract: 441,217. Changing signs. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and CROWE, D. C., Ericsson Telephone Works, Beeston, Nottingham. Aug. 30, 1934, No. 24966. [Class 3 (i)] A series of indicia are all brought in succession in front of each of a plurality of compartments in each of which is an electric discharge lamp or the like, so that by illuminating the lamps each at the moment when a required display letter, numeral, &c. is in front of it, a word, number or design is permanently seen by reason of persistence of vision. The indicia may be cut out of a base, or should the base be of transparent or translucent material, be formed by superposing thereon opaque matter at all parts other than such as will form the indicia. The base may be a rotating disc or drum or an endless travelling band &c., and the indicia may be viewed by reflected or transmitted light. The Figure shows a disc 1 bearing round its circumference the required indicia, and a plurality of lamp cells 6 disposed along an arc. The disc 1 is carried by the shaft 4 of an electric motor, the other end of the shaft having fixed thereon a brush 10 which wipes over distributer contacts 9, of which one is provided for each of the indicia on the disc 1. For a given set of connections between the contacts 9 and the lamps 5, a given set of indicia will occupy the spaces in front of the cells as each lamp is momentarily illuminated, and this set will be seen as a continuously illuminated display, with flicker at low speeds of the disc but free from same at higher speeds. Reversal of the direction of motion produces the same display, but change of display can be effected by change of connections between contacts 9 and lamps 5. This change may be made manually by plugs and sockets, or electro-magnetically by step-by-step switches, relays, &c. and a sequence of words may be displayed. The contacts 9 and brush 10 may be located at a distance from the disc and lamps, but the brush must rotate in consonance with the disc. In order to produce a travelling sign the contacts 9 and lamps 5 with their compartments 6 may rotate together, in either direction, and a complete circle of lamps would be provided. The disc 1 may carry a plurality of concentric indicia, each ring having its own set of lamps. Further, to produce a flatter arc for a given number of indicia, these may be repeated round the circumference, and a larger disc used. More than one display aperture may be provided for a single set of indicia, and two or more indicia may be caused to appear before the same light cell by illuminating a lamp more than once during each revolution. The duration of illumination depends on the widths of contacts 9 and brush 10, and if these are made wider to produce blurring, the strokes of the indicia in the direction of movement may be formed with serrated edges to approximate their appearance to that of the strokes at right angles thereto.

Filed: 1973-09-20
Abstract: 1445694 Coatings for measuring moisture content electrically MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 Sept 1973 [20 Sept 1974] 44287/73 Heading B2E [Also in Divisions B2 C3 Gl and H1] The humidity sensitive element of a humidity sensor comprises finely conductive particles dispersed in a resin consisting essentially of a reaction product of a chlorine containing polymer and an amino polyamide resin. A mixture of a chlorine containing polymer, e.g. chlorinated natural rubber, polyvinyl chloride, polyvinylidene chloride, chlorinated polyethylene and polypropylene, and amino polyamide resin e.g. produced by condensation of a carboxylic acid with an alkylene polyamide, is dissolved in a suitable solvent. Finely divided conductive particles, e.g. carbon black, graphite, silver or gold are added and the mixture ultrasonically mixed to form a paint to which an antioxidant agent, an ultraviolet absorbent and/or a plasticiser may be added. The paint is then deposited onto a ceramic e.g. alumina, glass or plastics insulating base to bridge a pair of electrodes mounted thereon and which may be interdigited. The assembly is then heated to cause the polymer to react with the polyamide resin and then soaked in an alkali solution to remove chloride ions which may be present and which would cause the film to exhibit ionic conductivity. Moisture in the atmosphere causes the resin to swell and the average particle distance to increase thereby resulting in an increase in resistance between the electrodes. Decrease in humidity causes the resin to shrink and the resistance to decrease. The sensor may be protected by a moisture absorbent protective coating of silicone resin.
