Title: Improvements in means for automatically controlling the discharge through the filter-bed in jigs used for coal or ore washing
IPC: B03B5/24
Filed: 1930-04-12
Abstract: 347,856. Washing jigs. PREPARATION INDUSTRIELLE DES COMBUSTIBLES SOC. ANON., 23, Boulevard de Strasbourg, Nogent-on-Marne, France. April 12, 1930, No. 11685. Convention date, April 13, 1929. [Class 82 (ii).] A filtering-bed. jig, e.g. a felspar jig for washing coal, is characterized by the control of the discharge of the heavy materials through the bed by automatic regulation of the magnitude of the water impulse through every point of the filtering bed, the magnitude varying in direct relation to the thickness of the layer of heavy material on the bed. Coal to be washed is introduced at 6 to a screen 4 carrying a layer of felspar 5 in a washing vat 1 in which a jigging action is produced by a piston reciprocating in a chamber 2. The coal is separated into layers 8, 9 of shale and coal respectively, the upper layer of coal passing over a ledge 10 into a trough 12. Between the washing bed and the piston chamber 2 is a chamber 13 extending across the whole width of the washer, the chamber 13 being closed by a lid 16 with a vent 17 on which is mounted a valve 19 which on rotation places the chamber 13 in communication with the atmosphere. The valve is operated by a toothed quadrant 28 keyed on a pin 27 which is rotated by a swinging lever 26 connected by a lever 25 to a float 24 which rests in the coal and shale layers on the bed, the mechanism being arranged so that as the shale layer deepens and the float rises the valve 19 is closed and the jigging action through every point of the bed is increased. A cut-off valve 30 may be provided between the orifice 17 of the chamber 13 and the valve 19. Alternatively the air chambers may be arranged on both sides of the washing bed and the mechanism for transmitting the motion of the float to the valve may be varied. The arrangement may be used in conjunction with the discharge controlling means described in Specifications 206,151, 254,709, and 306,169, [all in Class 82 (ii), Washing granular &c.].

Title: Electrically conducting transparent films
IPC: H01B1/00
Filed: 1951-05-21
Abstract: 703,778. Transparent electric heating panels. LIBBEY-OWENS-FORD GLASS CO. May 21, 1951 [May 25, 1950], No. 11770/51. Class 39 (3) A transparent resistance-heated panel comprises a sheet of glass 10 on which is a film 31 of transparent electrically conducting material, e.g. tin oxide, of varying electrical conductivity e.g. by being of varying thickness, and a pair of spaced, elongated electrodes 15, 16 in electrical contact with the film 31 and arranged at an angle to each other. The sheet 10 is trapezoidal in shape, and the electrodes 15, 16, which may be of sprayed-on copper or baked-on gold, silver or platinum, are on the non-parallel edges, 13, 14. The film 31 is sprayed on to the glass sheet 10, when the sheet 10 has been heated to its softening point, in the form of a 10 per cent. solution of stannic tetrachloride in isopropyl alcohol, the spray guns employed either delivering more liquid at the required area, or spraying for a longer period. In this way a film 31 of varying thickness is produced, the thicker film having a lower electrical resistance and consequently a greater heating effect. The thicker portion is formed on the wider edge 12 of the sheet 10 and is gradually thinned as the smaller edge 11 is approached to ensure a uniform heating of the panel, which may be a windscreen heated for de-icing purposes. Instead of varying the thickness of the film 31, its conductivity may be varied by varying the concentration of the filming solutions to different guns, or by adding materials, e.g. iron or antimony, to the solutions of different guns to increase or decrease respectively the electrical conductivity of the film 31.

IPC: G06K7/08
Filed: 1962-03-28
Abstract: 1,005,542. Permanent data stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 28, 1963 [March 28, 1962], No. 11824/62. Heading G4A. A read-only store comprises drive conductors 6, 7 formed into S-shaped loops, and sense conductors 4, the limbs of each S overlying a sense conductor. If current is passed through a drive conductor, the induction on a sense conductor due to the upper loop of the 8 balances that due to the lower loop. Data storage is effected by punching holes 9 in a copper sheet positioned so that the holes overlie the lower loops. Where a hole is present, the induction in the sense conductor due to the lower loop is greater than that due to the upper loop and an E.M.F. is generated in the sense conductor. Ternary information may be stored by selectively positioning the holes over the upper or lower loops. In a second embodiment, to reduce capacitive coupling between sense and drive conductors, the drive conductors are shaped as in Fig. 4 and the holes are positioned over the loops EFGH, WXYZ. Shielding conductors 5 are provided to prevent interference between storage locations. The roles of the sense and drive conductors may be reversed.
