Title: Improvements in or relating to electro-optical systems for television and the like
IPC: H04N5/66
Filed: 1930-07-14
Abstract: 355,896. Television. BANKS, G. B. and BAIRD TELEVISION, Ltd., 133, Long Acre, London. July 14,1930, Nos. 21253/30 and 12999/31. [Class 40 (iii).] The intensity of a beam of light is modulated in accordance with electric impulses by passing it through a moving medium, the optical properties, e.g. transparency, of which have been changed in accordance with the electric impulses immediately before the beam passes through it. In one embodiment, the medium comprises a neutral solution of sodium sulphate and an indicator such as phenolphthalein and flows through a tube 4, Fig. 1, under the action of a pump 1. The received television signals are applied to the electrodes 51, 52, located in the tube 4, Fig. 3, and shaped so as not to prevent the liquid flow. The medium splits up, under electrolytic action, forming a base solution at one electrode and an acid solution at the other, resulting in a change in the opacity of the liquid which modulates light from a source 6 directed on to a reconstituting mirror drum 9. The liquid is mixed in the reservoirs 2, 3 and the basic or acidic reactions vanish. The liquid may be carried round by an endless band dipping into a reservoir, the electrodes contacting with the band at one point. A cinema film may replace the endless band and the resulting variations in opacity developed and fixed. The film is used to modulate the beam of light scanning a viewing screen, replacing the liquid system described above. The medium may comprise glycerine in which iron filings are suspended, the electrodes being replaced by electromagnets. Electrostatic and mechanical stresses may be used where a change in the optical properties of the medium is produced. According to the Provisional Specification, the medium may remain stationary and the apparatus producing the changes in optical properties of the medium may move. A film dipping into a solution of potassium ferrocyanide may be used, blue striations being produced by the signal currents applied to electrodes contacting with the film. Alternatively a substance such as gum guaiacum may be used, which is rendered opaque by exposure to blue light and is clarified on exposure to red light.

Title: Information transducing apparatus
IPC: G11B15/12
Filed: 1966-05-13
Abstract: 1,102,484. Eliminating inter-record gaps; recording and playback. INTERNATIONAL BUSINESS MACHINES CORPORATION. 13 May, 1966 [1 June, 1965], No. 21262/66. Headings G4C and G5R. Use of two transducing heads spaced along a record carrier path enables records to be recorded and read without gaps. In a first embodiment, transducing (read or write) is possible at two stations along a tape path. Normally the first station (i.e. that reached by a given portion of the tape first) is used. When stop is ordered, the first station marks the tape (in a separate track from the data). The mark reaches about the mid-point between the stations by the time the tape actually stops. On restart, as soon as the mark is detected at the second station, the first station marks the tape again and both stations transduce data concurrently. When the second mark is detected at the second station, transducing continues at the first station only. The transduced data goes to or comes from a computer store. Both marks are erased after the second station. In a second embodiment, the tape may move in either direction, the two stations communicating with the computer memory directly and via a buffer (delay line or shift register) respectively, which communicates in which way depending on the direction of tape movement. This embodiment may operate like the first, mutatis mutandis, or as follows. The second station transduces and communicates directly with the computer memory. The first station transduces and communicates with its buffer. When the first station initially starts transducing it marks the tape. When this mark is detected at the second station, the first station marks the tape and the buffer starts refilling again. When this mark is detected at the second station, the first station marks the tape-and so on. When stop is ordered, the first station marks the tape and on restart the computer memory communicates with the buffer until the latter mark is detected at the second station after which the computer memory communicates (directly) with the second station again.

Title: Improvements in or relating to the protection of the walls of enclosures in which reactions take place under high temperatures and pressures
IPC: C01C1/04
Filed: 1919-08-29
Abstract: 158,593. Claude, G. Aug. 29, 1919. Ammonia, catalytic production from nitrogen and hydrogen; catalytic apparatics; high pressure apparatus. - Relates to the protecting of the walls of the enclosure in which an exothermic reaction is carried out under high pressure and at a high temperature, for instance the synthesis of ammonia using " hyperpressures " according to Specification 130,086. The layer of molten material G interposed between the chamber C in which the reaction takes place and the pressure - sustaining wall A, is, by selection, of bad thermic conductivity, neutral with respect to the bodies present, and of low vapour tension; suitable materials are a metallic chloride, caustic soda or potash, a eutectic mixture of the latter, and borax dissolved in boric acid. To prevent transmission of heat by convection, the molten material may be held stationary by the addition of solid material of bad thermic conductivity such as sand, coke, powdered magnesia, or magnetic oxide of iron, employed in a granular or pulverulent state in such a manrner as to form a paste or pulp. Substances such as litharge may be added to the molten material to absorb hydrogen &c. that may become dissolved therein and which might attack the wall of the enclosure. In the apparatus shown, the catalyst E is contained in an inner tube B, surrounded at the lower part by an electrical heating-device D and the reaction gases enter at the connection H, pass through the annular or helical space between the tubes B, C, then traverse the catalyst E where they are brought to reaction, and finally escape through the connection I. At the point where the gases enter, the temperature is insufficient to lead to deterioration of the wall A, and it is adequate to continue the molten material G to a height X at which the temperature ceases to become injurious to the wall. Several layers of liquids may be employed, the more fusible at the top and extending down to a level L and the less fusible from the level L to the level O; such viscous liquid may consist of boric acid containing an increasing proportion of borax.
