Vacuum tubes; low - pressure metallic-vapour apparatus. - Thermionic cathodes are formed with a hollow central support carrying a plurality of vanes, heating means for the support and vanes, and a surrounding member adapted to prevent loss of heat in order to obtain a high thermal efficiency of electron emission. In one example shown in Figs. 1 and 2, a stem 6 supports the cathode structure 7 and a grid 8 which may be formed of punched sheet metal supported by wires 9, 10 attached to a band 11, the wire 10 being extended and connected to a contact 12. The cathode 7 comprises a cylinder 13 of nickel nickel alloys, tungsten, or molybdenum containing thorium oxide and has an internal refractory insulating lining 14, a heater 17, and radial vanes 15 secured to a concentric cylinder 16 which may be polished externally. The ends of the heater 17 which may be of tungsten are connected by welding, riveting, or otherwise to the thickened end wall 18 of the cylinder 13 and a conductor 19 respectively, while the wires 20, 21 supporting the cylinder 16 and the wire 19 are sealed through the stem 6 and connected to contacts 23, 22. Heat conduction is reduced by cutting away the edges of the vanes 15 which may be of nickel or iron. Argon at a pressure of 50 microns or a vapour-yielding material is inserted in the envelope. When mercury is used, a shield 25 is mounted on the stem 6 to prevent heating of the base and the consequent formation of a high vapour pressure. The interior surface of the cathode and the vanes are coated with barium, caesium, cerium, a mixture such as misch metal, or oxides of these metals. A coating of barium carbonate may be applied to a nickel cathode which is then heated to 1300‹C, or thorium oxide may be used when the cathode is of tungsten or molybdenum. The vanes may consist of sheets of metal having bent end portions, Fig. 3, or may have a triangular shape, Fig. 4, or may be V-shaped, Fig. 5, the apex of the V being secured to the internal cylinder.

Title: Improvements relating to washer boxes for coal and the like
IPC: B03B5/24
Filed: 1927-04-26
Abstract: 288,824. Norton, B. April 26, 1927. Electrically - actuated valves; valves controlled by pilot or relay valves.-The depth of the heavy material in a coal &c. washer is regulated by an outlet gate 25 which is so disposed outside the washer that its closure surface moves across and intersects the outflowing material, the gate being actuated through a relay by a float 3 which sinks through the coal or light material and rests on the bed of heavy material. The float, which is carried in a vertical position by pivoted linkage 4 - - 6, actuates through lever 11 and a lost motion device 14 the pilot valve 20 of a relay cylinder 15. The exhaust port 27 is closed by the valve 20 before the inlet port 17 is opened and vice versa. In a modification of the relay mechanism, the exhaust port 52, Fig 4, is not fully closed until the inlet port 51 is fully open and the gate is opened against the tension of the spring 53 so that the degree of opening of the gate depends on the position of the float. A mechanical relay may be used, a sector 57, Fig. 5, being moved by the float to allow a continuously-operated pawl 63 to engage with a ratchet 58 by which the gate is actuated through a rack and pinion 60, 59. In a further modification the float which moves in guides completes an electric circuit to actuate the gate through a solenoid and dashpot. The float may be moved continuously across the washer-box to avoid the formation of a pocket by being secured to a slidable sleeve 42, Fig 8 having a feather 44 which engages a slot 45 in the fixed sleeve 43 and a continuous and right hand helical groove in the shaft 46 which is actuated by a compressed-air motor 48 supplied from the source producing pulsations in the washer-box. The float is hollow and open so that it may be approximately weighted and it may have a V- shaped lower end. Separate floats are provided to control gates at the in-flow and out-flow ends of the washer. Specification 288,881 is referred to.

Patent GB-981824-A (GB)
Title: Improvements in or relating to organosilicon compounds
IPC: C07F7/21
Filed: 1963-03-21
Abstract: Organosilicon compounds containing Si-OH groups are prepared by the reaction of an organosilicon compound containing at least one SiH group per molecule, and at least one group R on average on each Si atom, any remaining silicon valencies being siloxane links, with water, in contact with a catalyst selected from silver, silver oxide, copper oxide, platinum, chloroplatinic acid, Zeise's salt, palladium, rhodium or ruthenium, the metals being deposited on charcoal or aluminium oxide, if desired.  The groups R may be mono- or polyvalent hydrocarbon or halohydrocarbon radicals, and may contain ether linkages-not more than one on any one carbon atom (i.e. the compounds may contain silane and/or siloxane and/ or silcarbane structures). Compounds claimed per se are siloxanols of the formulae (R13SiO)xSi(OH)R13-x and <FORM:0981824/C3/1> where each R1 is a monovalent hydrocarbon or halohydrocarbon radical, x is 2 or 3, and Y is R1 or OH, in particular the cyclic compound [CH3Si(OH)O]4 and the compounds [(CH3)3SiO]2Si(CH3)OH and [(CH3)3SiO]3SiOH. A solvent may be used in the reaction, preferably one dissolving both the organosilicon compound and water, e.g. certain ethers and alcohols. Suitable temperatures range from below room temperature to about 150 DEG  C. The pH should be kept about 7, to avoid excessive condensation of the silanols, and a buffer solution may be used.  The examples describe the use of all the above catalysts in the preparation of a wide variety of compounds in dioxane, t-butanol, or ethylene glycol dimethyl ether as solvents. Typical products are (CH3)2Si(OH)C6H4Si(OH)(CH3)2, (C6H5)2Si(OH)2, C[CH2O(CH2)3Si(OH)(CH3)2]4, (CH3)3Si[OSi(CH3)OH]6OSi(CH3)3 <FORM:0981824/C3/2> , and the cyclic [OSi(OH)CH2CH2CF3]4.

E.), and PROFFITT, C. May 7, 1945, No. 11513. [Class 27] The actuating arm f of the coin register F is rocked in one direction (clockwise), preparatory to making a record, by the insertion of a coin K, and is returned to make the record when a hand-operated slider is drawn back. In the apparatus shown, the hand-operated slider is the latch bolt H of a lavatory door lock. The coin K, as it is thrust through the slot D, rocks a lever C which rocks a second lever E to bring a recess e<5> down to a roller h on the bolt H. The lower end of lever E is coupled to the actuating arm f of the coin register F, and simultaneously rocks the arm f (clockwise) ready for making the record. When the bolt H is drawn back by the outside handle j, to which it is coupled in the usual way by the inserted coin, the roller h rides out of the recess e<5> and along a straight portion e<4> of the second lever E, rocking it back and with it the arm f of the register to record the coin. When the lever E is thus rocked back, movement of the latch bolt H on slamming the door to, or operating the inside handle, is without further effect until a further coin is inserted to bring the recess e<5> down to the roller h.
