Title: Improvements in or relating to bricks
IPC: C04B33/02
Filed: 1933-06-21
Abstract: 413,861. Bricks. OVERY, E. A., 3, Brick Row, Commondale, and OVERY, J. H., 20, Coral Street, Lingdale, both in Yorkshire. June 21, 1933, No. 17724. [Class 87 (i).] Bricks are constructed from clay and ironstone shale, which are ground separately, then mixed in the desired proportions and puddled. The bricks are dried, and baked from 18 to 24 hours at a temperature of 900 to 1200‹ C. The proportions are preferably 25 parts clay to 75 parts ironstone shale, but 10 per cent of clay or 10 per cent of ironstone shale may be used.

Title: Improvements in or relating to high temperature electrolytic cells
Inventor: CHAUVIN GUY
IPC: A43B13/18
Filed: 1957-06-04
Abstract: 857,602. Fused-electrolyte cells. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 4, 1957 [June 7, 1956], No. 17749/57. Class 41 An electrolytic cell 1 for producing high purity metals and alloys by electrolysing a molten salt comprises a muffle 5 having at least the inner walls of metal, a crucible 11 of an electrically conductive refractory material, e.g. graphite, removably disposed in the muffle 5 and forming one electrode, a further electrode 25, and means 14, 12 electrically insulated from the muffle 5 for leading current to the crucible 11. The cell 1 communicates through slide valves 3, 4 with a cooling chamber 2. The crucible 11 is connected as anode through a conducting plate 12 and a wire 14, the plate 12 resting on insulation 13 in the muffle 5 which is heated by an electric heating element 7. A cathode 25 depends from packing 26 in the chamber 2 which has a cooling water jacket 23. Each valve 3, 4 comprises two members 34, 35 forming a casing in which is slidable a rod 36 carrying a plate 37 and a cover 38 which may be raised or lowered by rotating the rod 36 to actuate a cam 40 on the rod 36. There are joint packings between the members 34, 35, 38, e.g. at 33, 39. The cell is operated as follows:-With the chamber 2 removed, air is withdrawn from the muffle 5 by a pump attached to a valve 21, the muffle being heated. Next, inert gas is admitted at 17 into the muffle to restore the pressure, and the electrolyte salts put in the crucible 11. The salts, if desired after being degassed, are heated in an inert atmosphere or in a vacuum, and when molten, inert gas is introduced at 17, and leaves at 21. The chamber 2 is then fitted to the cell by screwing the valve 3 to the valve 4, degassed if desired, and the valves 3, 4 opened, the inert gas leaving at 24, and the cathode 25 lowered. When electrolysis is completed, the cathode 25 is raised, the valve 3 closed, and the cathode left to cool in the chamber 2. In a modification, electrical contact to the plate 12 is by a rod in the conduit beneath the plate 12 which leads to the exterior of the cell. Specification 851,444 is referred to.

Title: Method of annealing or other heat treatment of metals, more especially iron and steel
IPC: C23C8/22
Filed: 1930-06-10
Abstract: 352,677. Annealing ; cementation; gas generators. ELFSTROM, N. G., Fagersta, Sweden. June 10, 1930, No. 17796. [Class 72.] In the annealing or other heat treatment of metals, especially iron or steel, the annealing chamber is filled with a gas obtained by the passage of blast furnace gas, producer gas, or the like through a, layer of carbon heated electrically, so that the carbon content of the gas may be controlled. By increasing or decreasing the temperature of the carbon layer a gas is obtained which will carbonize or decarbonize the metal, or have no action on the metal. The gas may be preheated electrically before traversing the carbon layer. Air is supplied by pipe a to a gas producer A and the gas passes by pipe b to a regenerator B having a container m filled with charcoal and heated by a resistance coil c, the regenerated gas passing by a pipe d to the annealing chamber. The charcoal may be heated by an electric are. In Fig. 2 the gas generator and regenerator are combined in one structure, the lower part of the shaft m being surrounded by the heating coil c. The glowing layer'of carbon may be located in the annealing chamber which is electrically heated.

IPC: H02P27/02
Filed: 1953-06-26
Abstract: 745,840. Converting; automatic voltage/speed control systems. MULLARD RADIO VALVE CO., Ltd. Jan. 19, 1954 [June 26, 1953], No. 17800/53. Classes 38 (2) and 38 (4). [Also in Group XXXVII] In a supply and control system for an electric motor 30 which may be as disclosed in Specification 733,883, a feedback is derived from the output of the inverter to control the D.C. input thereto so as to counteract unwanted changes in the output voltage of the inverter. In one embodiment the feedback derived from the output of an inverter 1, 2, 3 is rectified at 51, amplified at 52 and compared with a control voltage in a comparator 50. The comparison is then fed into the phase circuits 41 which grid control the firing of the thyratron in the supply rectifier 40, thus to control the input to the inverter in the required sense. Where the inverter is fed from D.C. mains the feedback can be made to control a carbon pile regulator or a magnetic amplifier, thus to control the D.C. input to the inverter. Specifications 395,596 and 660,490 also are referred to.

Title: Improvements in or relating to floats
IPC: H01B7/12
Filed: 1942-12-15
Abstract: 587,441. Buoyant cables. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and MACDONALD, H. A. Dec. 15, 1942, No. 17848. [Class 36]. In a long flexible float built up of a number of rigid and connected buoyant elements 1, some of the elements are spaced by resilient rubber 10 expanded in position and moulded to the end of each adjacent element. The floats are used for the cores of buoyant electric cables or for supporting wires, ropes, or drift nets. The elements may consist of closed hollow containers or of cellular material such as wood or cork. The elements are connected by soldering the conical rigid end of one element to the flat flexible end of the adjacent one, by hook-andeye members, or by longitudinal flexible tapes 2 adhering to the elements. The space between the members is filled by rubber which may be inserted as a portion of rubber mix and expanded and vulcanised by heat during the final manufacture. A lapping 11 of textile tape forms a series of closed moulds for the rubber mix and also a bedding for conductor wires 12 which may be separated by a fabric layer 14 from a second conductor 13. A tough rubber sheath is then used to enclose the cable. Specifications 581,566 and 585,786 are referred to.
Patent GB-603494-A (GB)
Title: Improvements in the anti-felting treatment of materials consisting wholly or partially of wool
IPC: D06M13/02
Filed: 1945-07-13
Abstract: Wood fibres or materials consisting of wool fibres, e.g. yarns and fabrics are rendered resistant to felting and shrinking by subjecting them to the action of a saturated or almost saturated solution of potassium hydroxide in a monohydric alcohol diluted with an organic non-solvent or poor solvent for caustic potash which is miscible with the alcohol solution.  The wool may contain 12-18 per cent water, but the reagents should not contain more than 2-0 per cent.  The treatment is carried out at 15-20 DEG  C. By a saturated solution it is meant that when the temperature of the solution is raised to 30 DEG  C. a fine dispersion of solid caustic potash separates out.  In an example a 1 per cent (weight/volume) solution of potassium hydroxide in a mixture of 1 volume of n-butyl alcohol and 9 volumes of white spirit is used to treat wool for 1 hour.  After treatment the excess alkali is removed with dilute sulphuric acid, excess acid being destroyed by sodium bicarbonate and the white spirit removed with soap.  In another example a 1-3 per cent solution of caustic potash in a similar 1 : 9 butanol: white spirit mixture is used to treat a knitted fabric, a similar fabric being treated with a 0.6 per cent solution of caustic soda in the same solvent mixture.  The treated materials are resistant to felting.  Specification 592,880 is referred to.
