Title: Moisture measuring apparatus
Inventor: HART JOHN ALFRED HENRY
IPC: G01N27/04
Filed: 1955-10-10
Abstract: 814,395. Electric tests. ISOTOPE PRODUCTS Ltd. Oct. 10, 1955, No. 28852/55. Class 37. Apparatus for measuring the moisture content of a material (e.g. paper) having high resistivity comprises an A.C. source connected to the input terminals of a resistance-capacitance bridge having in one arm two electrodes adapted to contact the material at spaced points, means for balancing the bridge when the electrodes are out of contact with the material so that when contact is established between the electrodes and the material an unbalance signal is obtained, means for amplifying the unbalance signal, means for filtering out undesired frequencies in said signal, means for selecting that portion of said signal which corresponds to the resistive component of the current flow through the material and means for measuring the amplitude of that portion of the signal. As shown, the electrodes 315, are included in one arm of an R-C bridge 306, fed from an A.C. source 10 through a voltage limiter and having an adjustable resistance 314 and variable condensers 312, 316 to balance the bridge at a desired frequency when the electrodes are out of contact with (say) a sheet of paper, the moisture content of which is to be found. When the electrodes contact-the paper an unbalance signal appears at output terminal 310 and is fed to an attenuating system of series and parallel resistances having their junction points connected to contacts of a rotary switch 412. Through this switch the unbalance signal is applied to R-C coupled pentode amplifiers 501, 516 and thence to the grid of triode 528. The output of this triode is fed to a frequency discriminator 60 which negatively feeds back to triode 528 all undesired frequencies in the unbalance signal and supplies to the grid of triode 533 an unbalance signal of the correct frequency. This signal is then fed to a phase selector tube 701 through a switch 538, connected to provide a 90 degree phase switching action, and a variable capacitance 539 so that only the resistive component in the unbalance signal is applied to tube 701. This component is measured by a meter 801 in the cathode circuit of tube 701 and by means of a calibration chart the moisture content of the material may be found. Alternatively the amplifier circuits may be arranged to have an output varying directly with the logarithm of its input so that meter 801 may have a linear scale indicating moisture content directly.

Title: Improvements in or relating to the production of motive fluids for prime movers
IPC: F02K9/72
Filed: 1939-10-30
Abstract: 538,398. Liquid-fuel burners. WATSON, F. (Aktiebolaget Milo.). Oct. 30, 1939, No. 28996. [Class 75 (i)] [Also in Group XII] A motive fluid for prime movers such as internal combustion engines or turbines is produced by supplying heat to an oxygen carrying liquid such as hydrogen peroxide to separate oxygen containing gas from the liquid for supporting combustion of liquid fuel in a combustion chamber, the mixture of oxygen carrying liquid and gas being supplied to the combustion chamber in a whirling stream. As shown in Fig. 1, the liquid oxygen carrier is supplied through a pipe 14 to the lower end of a coil 15 lining the wall 10 of a combustion chamber to which liquid fuel is supplied by a nozzle 13. The coil is heated by the flame from the nozzle and oxygen carrying gas and liquid escape through apertures 24 at the top of the coil and enter an annular chamber 23 in the form of a whirling stream, the gas being supplied to the fuel to support combustion and the liquid flowing down the walls of the coil where it is further heated. Air for combustion enters through a pipe 17 and passes through passages 18, Fig. 2, arranged tangentially to passages 19 where it is given a whirling motion and delivered on opposite sides of the nozzle 13 to the fuel. The gases leave the combustion chamber through a pipe 25 and enter an insulated chamber 26 which is connected with the prime mover. Fig. 4 shows a modification in which the coil 15 discharges tangentially through an opening 34 into an annular chamber 33 and air for combustion supplied by a pipe 17 enters an annular chamber 30 and passes through inclined openings 31 to mix with the fuel.

Title: Catalyst for the combustion of dilute gaseous hydrocarbon mixtures
IPC: B01J23/89
Filed: 1955-10-12
Abstract: A catalyst to promote the combustion of dilute gaseous hydrocarbon mixtures containing oxygen, comprises an inorganic catalyst support (e.g. alumina, silica gel, or carbon) having a surface area of 50 to 300 sq. metres per gram, impregnated with a composition analysing: MnO2 30 to 75 per cent, CuO 10 to 50 per cent, CO2O3 1 to 25 per cent, and Ag2O 1 to 10 per cent.  In an example, an aqueous solution containing nitrates of manganese, copper, cobalt and silver in specified amounts, is heated to near boiling point and the mixture poured slowly with stirring over activated alumina (particle size .25 to .5 in. diameter), preheated to 80 DEG C.  Heating and stirring is continued until the nitrates are decomposed.  The resulting catalyst analyses 87 per cent of support and 13 per cent of impregnating coposition containing 50 per cent MnO2, 30 per cent CuO, 15 per cent CO2O3, and 5 per cent Ag2O.  A charge of this catalyst is loaded into a jacketed reactor, maintained at 405 DEG C. by an external electrical heating element, into which are fed waste gases obtained from the oxidation of ethylene and containing 1.25 per cent by volume of ethylene and 3.7 per cent of oxygen.  About 60 per cent of the ethylene is oxidized to CO2.  At a temperature of 505 DEG C., about 82 per cent of the ethylene is oxidized.  Higher temperatures up to 2000 DEG F. may be applied without reduction in activity of the catalyst.  The catalyst support may be formed into spheres, cylinders, or ring shapes.

Filed: 1926-11-20
Abstract: 285,584. Billing, N. Pemberton-. Nov. 20, 1926. Moulding phonograph records.-Sound records for gramophones, of the type comprising a foundation of paper, cardboard or the like coated with record material, are made by applying one or more cold dies to the cold blank and thereafter heating the die while maintaining the pressure. Preferably the dies are cooled again before being released. In the illustrated form upper and lower dies are provided with spiral chambers 12, and the upper die is raised and lowered through the medium of the handle 27 which is interlocked with a 3-way cock 20 controlling the supply of heating and cooling fluid. On starting with the dies closed as in Fig. 1, and lowering the handle 27 the initial movement operates the valve to cut off the heating fluid from both dies and supply cooling fluid thereto. During this period the slot 30 allows the handle to move without raising the die. When the dies are cooled the ram 19 is operated to release the die which is than raised. On the reverse movement, the final upward movement of the handle when the dies are in the closed position reverses the valve once more and re-supplies hot fluid to the dies. The ram operating-mechanism can be interlocked with the operating-handle if desirable. Reference has been directed by the Comptroller to Specification 18250/07.
