Patent GB-568912-A (GB)
Title: Sound operated electric gear
IPC: H04M1/65
Filed: 1942-12-14
Abstract: 568,912. Selective control by sounds. TELCS, M. L. Dec. 14, 1942, No. 20321/44. Divided out of 568,887. [Class 40 (i)] In a system for controlling apparatus by sounds, a gas-filled discharge tube is arranged between each frequency-selecting circuit and its associated relay and is biassed so as to be unaffected by inputs of small amplitude. In one arrangement, Fig. 3 (not shown), the discharge current of a gas-filled diode biases a triode amplifier tube with a relay in its plate circuit. In a modification, each selective circuit feeds the grid circuit of a gas-filled triode GT1, GT2, GT3 with one or more relay windings in its anode circuit. As shown, a relay can only operate when both its windings are operative. This is useful when (say) an automatic lift is to be controlled by speech, since vowel sounds have two or three characteristic frequencies, and in the vocal control of a typewriter. The arrangement may be associated with the selective circuits described in Specification 568,887.

[Also in Division F3] A collimator for use with a gun sighting system (see Division F3) comprises a cylindrical casing 40 adapted to stand upright on the ground and closed at the top by a plate 46 with a central opening 45 which is closed by a transparent disc 47 constituting a window for the passage of the beam when a cover 48 is removed. A carrier plate 53 is hingeably connected with the casing 40 by a member 54 and a wide bronze spring 51 affixed to a block 52 secured to the casing. Two springs 55, 56 are affixed to the top and bottom of plate 53, their ends being supported by a horizontal stud in a nut 58, which can be raised and lowered by means of a screw 59 having a milled head 60 to tilt the plate 53. The plate 53 has a threaded aperture 61 receiving an outer tube 62 into which an inner tube 63 is telescoped and is rotatable therein. A reticle 65 is mounted on the focal plane of an objective 64, a ground glass 66 being provided above it. An adjusting ring 67 is clamped to the tube 63 which is urged downwardly by a spring 70 which bears against a sleeve 72 fixed to the tube 63 and formed with a fork 73. A mirror 74 is pivoted in the fork 73 and is adjustable by means of a nut 75 accessible through a window 44 on the casing, covered, when not in use, by a cover 44a. The top edge of the adjusting ring 67 carries a scale 77 co-operating with an index mark 78 and the ring 67 also has a radial arm 81 with a threaded hole 82 through which a fixing pin 83 can be screwed to engage in one of a number of holes 84 arranged in the carrier plate 53. By lifting up the sleeve 72 and hence the tube 63 and adjusting ring 67 against the action of the spring 70, the tube 63 can be rotated and the fixing pin 83 transferred from one hole to another. The adjusting ring 67 is fitted with a spirit level 88. For pointing the collimator at an object, a lens 92 may be cemented over a clear spot left on the ground glass screen 66, the distance of the lens from the reticle 65 being equal to its focal length, so that in conjunction with the lens, the collimator can be used like an astronomical telescope. Specification 258, 593 is referred to,

Title: Digital raster display system
IPC: G09G5/02
Filed: 1975-05-15
Abstract: 1503362 Cathode-ray tube displays INTERNATIONAL BUSINESS MACHINES CORP 15 May 1975 [11 June 1974] 20485/75 Heading H4T The invention is directed to a computer driven digital television type (i.e. raster scanned) display system and is particularly concerned with providing a system which allows selective modification of data and the erasing of data without erasing overlaying material, e.g. data common to intersecting vectors, whilst reducing the storage requirements which such manner of operation requires in prior art systems. This is brought about by employing a technique described as 'on-the-fly' or 'implicit refresh' in which all displayable data retains its identity in computer coded form up to the final stages of video signal generation. As described, a refresh buffer 28 (Fig. 1) is loaded (e.g. from a computer) with lists of coded data each list representing displayed elements having an endpoint on the same raster line the raster lines being different for each list and the lists being transferred in operation to an intermediate buffer store 38 from which they are transferred, in synchronism with the display of raster lines, to a symbol generator 40 and a vector generator 42. The latter then operate to generate from each list the sequence of binary digits (video ON-OFF signals) appropriate to the raster line represented by the list and returns to the intermediate store 38 only that coded data which relates to display elements which extend to the next raster line to that represented by the list. The intermediate buffer 38 is organized into a pre-load area and an active area with a total capacity of 256 32-bit words data words being transferred from buffer 28 to buffer 38 as room becomes available in the pre-load area and from the latter area to the active area as required for display. All vector and symbol video data are assembled in "one line" of a partial raster assembly store (PRAS) 44, which has a capacity of "two lines", during the line time preceding it display and then read out at video rate whilst the next line is being assembled. The read out video is then mixed with synch and timing signals in output driver 46 and supplied to the display tube. Three PRAS's 44, one for each primary colour of a colour display tube may be driven by the generators 40, 42. The invention is described in the context of its use in a system in which each of a plurality of colour display consoles may interact with a "host" computer via a trackball (for cursor control), function keyboard, alphanumeric keyboard and a light pen.

Title: Process for production of manganese metal and chlorine
IPC: C25B1/26
Filed: 1953-07-27
Abstract: 747,772. Electrolytic production of manganese. OLIN MATHIESON CHEMICAL CORPORATION, [formerly MATHIESON CHEMICAL CORPORATION]. July 27, 1953 [July 28, 1952], No. 20759/53. Class 41. A process for the production of manganese metal and chlorine from manganese chloride comprises circulating an aqueous catholyte solution of manganese chloride and ammonium chloride through a cathode compartment of a cell divided by a diaphragm, circulating an aqueous anolyte solution containing a soluble chloride through an anode compartment of the cell, the soluble chloride comprising hydrogen chloride, an alkali metal chloride, or an alkaline earth metal chloride, passing a current through the cell and depositing manganese metal at the cathode and discharging chlorine gas at the anode. The catholyte is fortified with manganese chloride and recirculated to the cathode compartment. The catholyte may be prepared and fortified with pure manganese chloride and pure ammonium chloride, but the manganese chloride may be derived from a manganese ore, impurities being precipitated by addition of sodium sulphide or hydrogen sulphide and ammonia. Sulphur dioxide or sodium thiosulphate may be added to the catholyte to prevent oxidation of the manganese metal and to avoid formation of manganese dioxide. The anolyte may be a solution of hydrochloric acid or sodium chloride, and is refortified with acid or salt and recirculated to the anode compartment. When the anolyte contains sodium chloride, sodium ions accumulate in the catholyte, and effluent catholyte may be cooled to crystallize excess sodium chloride from the solution. The cell preferably comprises a plurality of anode and cathode compartments separated by diaphragms, which may be of " Vinyon " (Registered Trade Mark). The anodes may be of graphite and the cathodes may be of stainless steel or titanium. Stainless steel cathodes may be dipped in dilute sodium silicate solution before use to facilitate removal of manganese metal. Effluent chlorine gas is dried, such as by scrubbing with concentrated sulphuric acid, and may be compressed.

Abstract: 1,069,037. Data handling apparatus. BUNKER-RAMO CORPORATION. May 18, 1965 [May 26, 1964], No. 21049/65. Heading G4H. A plurality of transmitting stations, preferably cathode-ray tube key sets, are linked to one of several sub-stations which in turn are connected to sub-systems, so that the reply from a sub-system to a query from a transmitting station entered via the function keys is indicated on the screen of the associated cathoderay tube. In the stock quotations system described each sub-station comprises (1) keyboard sampling equipment, (2) connecting lines to its associated control system, (3) storage and timing equipment and (4) cathode-ray tube control equipment. The keyboards 22 of the key sets are sampled in succession by a keyboard drive 66. If a key is depressed one or more of the lines of a seven wire multiple 72 will conduct current via a keyboard analyser 78 to a conventional strobe circuit 86 which converts the parallel data bits into a serial signal which at the appropriate time is gated into a magnetostrictive delay line 58. The stored data for the key sets is interlaced in the delay line with the query and reply characters for key sets 1, 5, 9 in the first section A, for key sets 2, 6, 10 in section B &c. Under the control of time counters 62, a gate 118 is opened to pass the stored query characters via a modulator - demodulator unit along conventional transmission lines 42 to the control sub-system, where the query is stored and analysed to produce a reply along line 40. This is transmitted via a timing gate 136 to the delay line 58. An " indicator character " which determines the mode of display of the reply on the cathode-ray tube screen, e.g. alphabetics or numerics, is transferred to a temporary storage register. The data read out from the delay line is shifted in parallel via a register 152 to a second register 154, four bits being then passed to a character generator 156 and a fifth to a small character control circuit 158 to ensure correct position of fractions. The character generator which includes a diode matrix translates the signal into a permutation code of 48 bits, a strobe circuit converting the signal into parallel form and passing it to a video driver 178 which applies a positive voltage to all the cathode-ray tubes except that one being supplied with data. The code signal is supplied in the form of a negative signal to intensify the beam to create the desired character, the characters being represented on the screen serially line by line.
