Abstract: 642,216. Valve generating circuits. GENERAL ELECTRIC CO., Ltd. April 30, 1948, No. 11891. [Class 40 (vi)] A frequency doubling circuit comprises an input circuit tuned to the basic frequency and comprising a pair of parallel wires 1, 1<SP>1</SP> adjustably bridged at 3 and connected in push-pull to the grids of valves 2, 2<SP>1</SP>. An output at the doubled frequency is taken in parallel between the anodes and cathodes of the valves which are connected in pairs as shown to the outer and inner conductors 4<SP>1</SP>, 4 of a concentric line resonator tunable by a bridge 5. An input at the basic frequency is coupled in by a loop 6, and an output at the double frequency is taken from a loop 7. The input loop is tuned by a variable condenser 8 after the initial adjustment of the bridge 3. This enables the line 1, 1<SP>1</SP> to be made shorter and also, since the condenser is connected between points which are at the same potential with regard to the output frequency, the input circuit can be tuned without affecting the output circuit. Thus the output circuit is tuned first.

Title: An improved apparatus for carrying out endothermic reactions
IPC: C01D5/00
Filed: 1951-05-23
Abstract: <PICT:0720170/III/1> In an apparatus for carrying out endothermic reactions between finely divided solid materials and gases of the type wherein a suspension of the solid material in a carrier gas is injected in the form of a jet from a first nozzle into a reaction chamber which is maintained at a high temperature, and fuel and combustible gas mixture is injected into the reaction chamber from a second nozzle, means are provided for creating sonic waves in the carrier gas in order to create a vibratory movement of the carrier gas before entry into the reaction chamber.  As shown in the Figure a reaction zone 1 is fed with a suspension of solid particles from pipe 5 and jet 4, and with a fuel/oxygen mixture from pipe 8 through jet 7.  Gas is fed from line 5 and solid is fed from hopper 11 and line 9 to pipe 5.  The flow of gas from line 5 is periodically interrupted by means of a perforated rotating disc 15 placed across line 5 and provided with a gland. Solid reaction products may be withdrawn at 13 and gaseous products at 14.  The apparatus is suitable for the reduction of finely divided iron ore by means of reducing gases such as carbon monoxide or hydrogen, for the production of sodium sulphate and hydrochloric acid from sodium chloride, sulphur dioxide, oxygen and steam, for the production of cyanides from sodium carbonate, nitrogen and carbon, for the production of calcium cyanamide from calcium carbide and nitrogen or calcium carbonate and ammonia, or for the production of water gas from finely divided solid fuels and gases or vapours such as water vapour or carbon dioxide.  In an Example of the latter application when a suspension of finely pulverized coal having a maximum diameter of the order of 1 millimetre is injected in a stream of oxygen and steam, the frequency of the sonic waves applied is between 2,000 and 7,000 cycles per second.  In the production of calcium cyanamide using the above described apparatus calcium carbide is fed from hopper 11 and nitrogen through pipe 5; a mixture of fuel gas and oxygen is injected from pipe 8 and nozzles 7, which may be of annular formation, and the solid calcium cyanamide production product is withdrawn at 13.  Specification 673,161, [Group XII], is referred to.

Abstract: 856,551. Masted lift trucks. CLARK EQUIPMENT CO. April 10, 1959 [April 28, 1958], No. 12112/59. Class 78 (3). In a masted lift truck the flow of hydraulic pressure to the mast extending ram 8 and the mast tilting rams 10 is cut off when the solenoids of normally open valves 18, 19 are energized by the closing of switches 16, 17, consequent upon movement of the mast to a predetermined position. Further switches 20, 21, operable by initial movement of the lifting and tilting valve control levers, are provided to de-energize the solenoids of valves 18, 19 to permit the rams to operate. Switch 16 is mounted on the fixed section of the mast and is operated by a cam on the movable section which allows the switch to close when the mast has been extended by a predetermined amount. Switch 17 is mounted on a wing of the truck and is closed when it is engaged by the fixed section in its rearmost position.

Abstract: The invention comprises polymeric nitrogenous dialdehydes having monomeric units of formula: <FORM:0944459/C3/1> where Q is the radical of the monomeric unit in dialdehyde starch, R is an ether linked alkylene or hydroxyalkylene radical and R1 is a methyl or ethyl radical, and quaternary ammonium derivatives thereof.  A specified class of the latter comprises compounds with monomeric units of formula: <FORM:0944459/C3/2> where Q, R and R1 have the meanings above, R2 is an alkyl radical containing up to 18 carbon atoms and X is a chloride, bromide, iodide or sulphate anion.  The novel derivatives are made by treating an aqueous slurry of a nitrogen-containing starch ether (see U.S.A. Specifications 2,813,093 and 2,876,217), with sufficient periodic acid or sodium periodate to completely oxidise the free C2 and C3 hydroxyl groups to aldehyde groups.  The resulting dialdehydes are cationic in nature, and are readily dispersible in hot water to give dispersions which are strongly substantive to cellulose fibres.  They may be employed as beater or wet-end additives to cellulose fibres in the production of a high wet-strength paper for e.g. towelling, wrapping paper and paper bags.  The invention further comprises an aqueous dispersion of cellulose fibres having adsorbed thereon from 0.5 to 5% by weight of the starch dialdehydes.  In an example, bleached sulphate pulp is slurried in an aqueous dispersion of Q-O-C2H4N(CH3)2 where Q is dialdehyde starch moiety.
