Title: Apparatus for analysing gases
IPC: G01N7/04
Filed: 1934-05-24
Abstract: <PICT:0433979/III/1> A gas analysis apparatus comprises a chamber containing a solid reagent adapted to remove a component from the gas, internally actuated means for passing a given volume of gas through the chamber, and a vacuum gauge for measuring the reduction in pressure.  In the form shown in the Figure, a measuring chamber 2 is connected at both ends by passages 4<1>, 5<1> in a cock 6 to the absorption chamber 3, and a spherical body 10 moving freely within the chamber 2 is moved to and fro by tilting the latter thus driving the gas through the absorbent.  The cock 6 also has a passage 11 communicating with the vacuum gauge in the testing position and a passage 7<1> communicating with the source of gas in the filling position, in which passage 4 is open to the atmosphere.

Abstract: 584,460. Rotary meters. LINDE AIR PRODUCTS CO. Aug. 18, 1944, No. 15783. Convention date, Oct. 29, 1943. [Class 110 (ii)] [Also in Group XIX] A plant for transferring liquid 11 at low temperature (such as oxygen) from a container 10 to a receiver 21, includes a meter 75 which is pre-cooled by the passing of the liquid from 10 through a jacket 76, before the normal metering of the liquid commences. Cooling liquid passes from an inlet 27 to an outlet 29 and valve 30, and returns to the container. Gas forming passes through a pipe 31 to the upper part of the container, which is fitted with a pressure relief valve 15. The meter may be of the meshing screw type as shown, one or more of the rotors, and/or the bearings, being made of a selflubricating material such as bonded carbon or graphite, which are unaffected by low temperatures. The meter recording mechanism 72 is kept at a distance from the meter by pillars 71, and is driven by a shaft 69 all of low thermal conductivity to prevent frosting of 72. The liquid 11 may be under pressure. The meter rotors are open at each end, liquid passing from a pipe 18 to a pipe 19. The parts 10, 21 are surrounded by insulation 13, 34. For starting up, valves 17, 28, 22, 30 are opened, and the pump P operated to force liquid through the meter jacket. After cooling of the meter, the valve 28 is closed and the liquid is forced past a pressure-relief valve into 18. After sufficient liquid has passed through the meter, valve 28 is opened and valves 17 and 22 closed, vapours passing through the pipe 29 to 10. A discharge pipe 35 leads liquid to a vaporising coil 37, which is heated, and to a line 38, heating coil 42 and storage container 43. Pressure-regulating valves 40, 44 are provided, and gas may pass a pressurerelief valve in pipe 41 leading back to the receiver 21. The valve 40 opens when the pressure in 38 is reduced below a certain figure, and allows liquid to flow through 35.

Abstract: 312,279. Spanner, H. J., and D÷ring, U. May 23, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vacuum tubes.-Coatings are applied to electrodes by surrounding them with a gaseous compound which is heated until it decomposes and deposits the required substance, such as an alkaline earth metal which may subsequently be oxidised. Unstable compounds preferably are used, e.g. those of the alkaline earth metals. " Alkyls or alkylhalides of the aliphatic or aromatic series, aryls, acetonates, naphthalates, or amides may be used as well as corresponding compounds and substitution products of paraffins and olefines. " The heat source may be the body itself, a heating element disposed within the vessel containing the compound or externally of the vessel, a high-frequency field, or a discharge between electrodes of which one may be the body to be coated. With a separate heating element the temperature should be such that only a slight deposit is formed on it. '1'he surface of the body may be rendered porous by corrosion or etching, by oxidation and subsequent reduction, by amalgamation and subsequent vaporization of mercury, or by chemical treatment e.g. by applying a coating of carbide or of various oxides such as oxides of aluminium, zirconium, nickel, cobalt, and amphoteric oxides generally, which are subsequently reduced by the deposited metal. Various unstable compounds of potassium, rubidium, caesium, &c. may be used, and two or more metals may be deposited simultaneously.

Abstract: 497,229. Transmitting mechanical power. SULZER FRERES SOC. ANON. June 14, 1937, No. 16439. Convention date, June 27, 1936. [Class 38 (iv)] In a system in which the voltage of a generator driven by an internal-combustion engine is regulated in accordance with the speed, so that, at any one setting of a controller, the load on the engine is constant, comparison may be made between a wattmeter and a fuel setting indicator so that faulty working will be revealed by divergencies of the indications from the appropriate readings. The generator 2 driven by the engine 1 supplies motors 4 and also drives an exciter 3 in circuit with the generator field 6 and regulating resistance 7. The generator output is indicated by wattmeter 59. The engine may be run at any of several speeds or the torque may be altered in accordance with the setting of controller 62 which adjusts (a) the spring loading on the governor through leads 32, 42 and windings 41 supplying electromagnets operating valves 34, 43 controlling pistons 36, 38, bringing one or two additional loading springs into action, and (b) field resistance 7 through electromagnets 22, 21, lever 19 and valves 10 controlling admission of pressure fluid on to top of piston 9. The governor 14 adjusts lever 25 pivoted at 24, this lever at its lower end adjusting rod 26 connected to the fuel injector control members, and at its upper end moving pointer 15 over a dial. The pointer 15 also adjusts the upper end of lever 19 so that the value of field resistance 7 depends upon both the setting of controller 62 and the engine governor. The indications of the wattmeter 59 should approximate to the indication given by pointer 15 on scale 53.

Abstract: 1,220,103. Monitoring records. BELL & HOWELL CO. 5 April, 1968 [7 April, 1967], No. 16452/68. Heading H4J. [Also in Divisions G1 and G5] A discrepancy indicator for comparing mechanically, magnetically, optically or electrostatically recorded master and copy signals is designed to give error indication signals when the copy signal falls below two different levels, e.g. 3db and 6db, relative to the master signal. The master record MR is played back by head 30 and the signal amplified, equalized and fed to copy recording heads 46, the master and copy records being subsequently played back by heads 29, 45 for comparison. The master signal is amplified 21, rectified 25 and integrated 27 to give a slowly varying positive D.C. voltage on line 43. Each copy channel is divided into two similar subchannels which, via potentiometers 65a, 65b provide slowly varying, negative D.C. voltage levels on lines 75a, 75b at a nominal 3db and 6db above the D.C. level on line 43. The outputs from the respective copy subchannels are compared with the master signal in zero-crossing detectors 77a, 77b to operate trigger circuits 81a, 81b associated with SCR-controlled warning lamps 113a, 113b when the signals on the respective copy subchannels fall to their 3db and 6db limits. The drive to the offending copy is preferably halted when the 6db limit is reached. The stop control relay 119 is also associated with normally open and closed contacts 123, 125 respectively, arranged to apply a pseudovoltage V 3  to the rectifiers 57a, 57b to prevent the indicators operating when copying is not in progress.

Title: A process of separating hafnium and zirconium
IPC: C01G25/06
Filed: 1924-07-12
Abstract: Hafnium and zirconium are separated by fractionally crystallizing, precipitating or heating the mixed sulphates.  The crude material may be dissolved in sulphuric acid or fused with an acid sulphate and on allowing the solution to stand or adding sulphuric acid, alcohol, or other precipitating agent basic sulphates are separated containing a different proportion of hafnium.  Or double salts may be formed by adding ammonium sulphate or the like to the sulphate solution, whereupon salts separate out which are richer in zirconium than the original material; or a precipitant such as barium chloride or alcohol may be added to the solution containing double sulphates when precipitates are formed which are richer in hafnium. Alternatively, a mixture of zirconium and hafnium sulphates may be heated at 450-600 DEG  C. in an atmosphere of air or sulphur trioxide or a neutral gas, or in a vacuum, so that the zirconium sulphate is decomposed to the oxide whereas the hafnium sulphate mostly remains and may be extracted with water; and in this process a substance having an affinity for sulphuric acid, such as barium oxide, may be mixed with the mixed sulphates before the calcination.
