Title: Improved process of manufacturing carbon filament for incandescent electric lamps
IPC: H01K1/06
Filed: 1921-08-17
Abstract: 169,148. Nishikawa, K. Sept. 12, 1920, [Convention date]. Filaments; residual gases.-To eliminate magnesia in the manufacture of carbon filaments, raw cotton or cellulose is first refined chemically and the filament made of such cotton is refined by subjecting it to a high temperature in a rarefied atmosphere of carbon tetrachloride or other halogen carbon gas. The cotton is first reduced to a powdery form by treatment with an acid, for example a 50 per cent solution of hydrochloric acid at 60‹ C. The product is boiled in distilled water to eliminate soluble salts. A filament is made from a zinc chloride solution of the cellulose and hardened in alcohol, then treated with a 5 per cent solution of hydrochloric acid, then successively with hot and cold distilled water, and is then carbonized by heating to 1450‹ C. for 48 hours. The filament is then treated with strong nitric acid, and is washed and dried. Then it is heated by electric current, for example in the lamp bulb, in an atmosphere of carbon tetrachloride at 3 m.m. pressure. The gas may then be replaced by fresh gas at the same pressure and the bulb sealed. Specification 2136/82 is referred to.

Title: Improvements in rotative winged aircraft
IPC: B64C1/00
Filed: 1947-08-08
Abstract: 634,340. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21891. Convention date, July 7, 1942. [Class 4] A helicopter is provided at the rear of the rotor with a floating stabilizer, freely pivoted on a substantially horizontal axis and positioned in such a manner that during both translational flight and vertical ascent it assumes an attitude substantially parallel to the direction of air flow, variations in said attitude, to suit different flight conditions, being achieved by an adjustable tab pivoted on the trailing edge of the stabilizer. The stabilizer 11, Fig. 2, is freely pivoted on a substantially horizontal transverse tube 13 and is provided with an adjustable tab 12 pivoted at 15 and formed with a lever 16. The extremity of lever 16 is pivoted to one end of a threaded telescopic member 17, 18 of which the other end is connected to a universal coupling 21 offset below the axis of the tube 13. Rotation of the universal coupling 21 to cause extension or contraction of the member 17, 18 is effected by gearing 24 directly controlled by the pilot through a chain drive 27. Fig. 4 shows the tab 12 set to give the stabilizer 11 a positive incidence relative to the airflow direction h. When the airflow changes to the direction v and moves the stabilizer into the position 11a differential movement of the linkage 17, caused by the offset pivot b, moves the tab 12 into line with the stabilizer 11 and causes the latter to lie at zero incidence with respect to the airflow direction v. In most cases the centre of pressure of the aerofoil is located aft of the axis of the tube 13 and in order to balance the rotational effect caused by the lift acting about said axis, a bias spring z is fitted. In an alternative arrangement, Fig. 6 (not shown), a constant setting of the tab 12 relative to the stabilizer 11 irrespective of the attitude of said stabilizer is obtained by making the centre line of the control rod 17 approximately intersect the axis of the tube 13. On helicopters fitted with two transversely disposed contra-rotating rotors, two independent stabilizers may be located, one under the influence of each rotor. Specifications 393,976, 410,532 and 506,404 are referred to.

Title: Improvements in or relating to the heat treatment of particulate solid materials
Inventor: NEWTON WILLIAM HENRY
IPC: F28C3/16
Filed: 1960-06-23
Abstract: <PICT:0989778/C4-C5/1> A method of subjecting particulate solid material to a heat treatment, e.g. for rendering small volatile coals smokeless or for the rapid heating of granular anthracites, comprises introducing the material (in a carrier gas) at 1 into a gaseous stream, e.g. produced by a burner 3 for heating a vessel 6, so that the material surrounds the stream, and introducing the stream and the material tangentially into the vessel 6 one or more inlets so that a swirling motion is then induced in the stream, subjecting the stream and solid to heat treatment and separating the treated solids and the gas in the vessel 6.  The separation is carried out by centrifugal action in the vessel 6, solids leaving at 7 and gases at 8.  The vessel 6 may be externally heated or, if air is used as the carrier stream at 1, the heat of reaction in the vessel 6 may be wholly or partly sufficient.  Heated sand may be introduced into the vessel 6. The gases leaving at 8 may indirectly preheat the carrier gas/solid supply, see Fig. 3 (not shown), and the air and fuel (gas) supply to the burner 3.  In a further embodiment, Fig. 4 (not shown), the carrier gas and entrained solids are delivered to a cyclone separator to which gases from the line 8 are also delivered, the solid material being heated in the separator. On leaving the separator, the solids are entrained in a second gas indirectly preheated by the gases leaving the separator, for delivery to the vessel 6.  In both the embodiments of Figs. 3 and 4, a cyclone separator may be included in the gas line from the vessel 6 just prior to the indirect heater, and coal fines from this separator may be used as fuel in the burner 3.

Patent GB-619695-A (GB)
Title: Electrical control system
IPC: H04Q1/18
Filed: 1946-07-26
Abstract: 619,695. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd. July 26, 1946, No. 22358. Convention date, Sept. 17, 1945. [Class 40 (i)] [Also in Group XXXIX] An electrical control system comprises actuating means including two opposed elements, each responsive to anode current from a different one of two triodes, the actuating means being operative when the opposed elements are in balance, and means for initially inhibiting the operation of the actuating means for a limited period longer than transient undesired balancing of said element during operation, whereby false operation of the actuating means is prevented. As shown applied to an automatic telephone system, a register comprises a number of switches such as RB, which are set according to the digits dialled. The brushes of the register and the selector switch feed the grids of two triodes V1, V2, the cathodes and grids of which are cross-connected. Energization of register relay AR1 causes one or other triode to conduct to energize one winding of a differential relay VR, which causes operation of a magnet P so that the selector brush T hunts over the terminals ST until it finds a potential matching that on the selected register terminal. Both triodes then conduct and the differential relay VR relapses to release relay GR and magnet P. Grounding relay GR holds sufficiently long to prevent release of the magnet P due to movement of the selector brush from one contact to another causing momentary reversal of the relative polarity of the brushes. In a modification, Fig. 2, the anodes feed the differential relay through blocking rectifiers S1, S2, which form with resistances R3 a closed circuit through each winding so as to increase the rate of decay of magnetic field in the one winding and also the rate of increase of field in the other. This reduces the time during which the fields neutralise one another so that the armature of relay VR is not released by transient reversal of polarity. In a further modification, Fig. 3, energization of the register relay AR1 in the manner already described causes differential relay VR to energize and also energizes relay AR2 to operate clutch magnet P to cause the selector to hunt. When the selector finds a matching potential, relay VR relapses to remove earth potential from the auxiliary electrode of gas-filled tube GV, which fires to energize relay GVR which releases the magnet P to half the selector brush. Instead of both tubes firing when matching potentials are found, it can be arranged that both will shut down. The invention can be applied to remote control systems for electric lifts, guns, calculating machines, telegraph, ticket and other automatic printers. Specification 592,846 is referred to.
