Title: Inerting systems for aircraft or other fuel tanks
IPC: B64D37/32
Filed: 1972-01-13
Abstract: 1331735 Minimising explosion risk in aircraft fuel tanks PARKER-HANNIFIN CORP 13 Jan 1972 [28 Jan 1971] 1707/72 Heading ASA An aircraft fuel tank inerting system involves scrubbing the tank fuel of oxygen during flight by circulating it through mixing means in contact with a flow of inert gas; the system also includes the known step of maintaining an inert gas atmosphere in the tank vapour space to dilute and vent oxygen liberated from the fuel during ascent and to pressurise the tank against entry of air during descent. Tank 1 with vapour space 2 is supplied through nozzle 4 with N 2  from liquid source 5 via line 3 in response to differential pressure sensing device 6. The tank also has vent valve 7, optionally with air inflow means, and fuel inlet valve 9 attached to nozzle 10. Fuel pump 11 pumps fuel from tank 1 into engine feed 12 and also circulates fuel through mixing nozzle 14. Nozzle 14 can have its suction port 15 (including gas flow restrictor 20) in communication either with N 2  source 5, or with vapour space 2, via line 16, control valve 17 and either conduit 18 or 19. When solenoid 21 of valve 17 is energised by differential pressure sensing device 22 sensing a pressure drop, N 2  flows from 5 via line 18, valve 17, line 16, restrictor 20 and port 15 into mixing nozzle 14 where it scrubs O 2  from the fuel circulating therethrough and is discharged into tank 1. When 21 is de-energised valve 17 closes line 18 and puts port 15 in communication with vapour space 2 via lines 16 and 19. As fuel is pumped through 14 the suction at 15 draws gas from 2 into the nozzle to mix with the fuel. Thus port 15 and line 16 are kept free from fuel that would otherwise enter therein when 16 is disconnected from supply 5. The system serves to maintain the oxygen content of the ullage gas always below 10%.

Filed: 1947-01-25
Abstract: 640,913. Weighing-apparatus. AVERY, Ltd., W. & T. Jan. 25; 1947, No. 2369. Convention date, Feb. 24, 1944. [Class 143] A weighing scale incorporating a hydraulic force transmitting system comprising load supporting hydraulic capsules connected to counterbalance actuating bellows, is characterized in that some of the bellows are arranged to receive hydraulic pressure internally, and the remaining bellows are arranged t o receive hydraulic pressure externally, in order that the errors inherent in one type of bellows may compensate the errors inherent in the other. A load platform 10, Fig. I, is supported on four capsules 16 which are each hydraulically connected by a tube 22 to a receiving element 23 which transforms the hydraulic c pressure therein into mechanical force which, through a gathering lever 26 and a rod 29, is transmitted to a counterbalancing weighbeam 31. The receiving elements 23, Fig. IV, which are connected to diagonally opposed capsules, have internally stressed bellows which at their lower ends are secured to plugs 43 which are adjustably and detachably attached to the lever 26, the upper ends of said bellows being secured to connectors 37 which are adjustably and detachably attached to a base member 25. Receiving elements 46, Fig. V, which are connected to the other pair of capsules, have externally stressed bellows, the ends 51 of which are sealed to cupshaped members 47 which are adjustably and detachably attached to the base member 25, the closed end 52 of each of said bellows being in contact with the pointed end of a member 53 which bears on a knife edge 55 adjustably and detachably attached to the lever 26. In another embodiment, Fig. VII, each capsule is connected, through branch tubes 60, 61 and a main tube 59, to both an internally stressed bellows receiver 62 and an externally stressed bellows receiver 68, which receivers are individually adjustable longitudinally along a gathering lever 67 to enable the error in each capsule, bellows assembly to be accurately cancelled. This arrangement obviates the necessity of placing the load centrally on the weigh platform. In a modification of this embodiment, Fig. X, longitudinal adjustment of each pair of receivers is effected simultaneously by rotation of circular plates 82, 69 between which the two receivers are secured diametrically opposite one another, said plates being rotatably mounted on the gathering lever and on the base member by means of spigots 70 and 84.

Title: Improvements in and relating to the production of hydrogen
IPC: C01B3/34
Filed: 1929-01-25
Abstract: 328,048. Tyrer, D., and Imperial Chemical Industries, Ltd. Jan. 25, 1929. Hydrogen is produced by bringing methane or gases containing it into contact with molten iron, and blowing the iron with air or other gas containing oxygen to burn out the carbon produced in the reaction and dissolved in the iron. In the example given, molten iron 2 is contained in a vessel 1 divided by a partition 3 into two compartments 4, 5. Methane or a gas containing it is blown through a pipe 6 into the iron, and the hydrogen produced escapes from compartment 4 through a pipe 7. Air is supplied through a pipe 8 to compartment 5, part passing through a valve 9 to the space above the iron to ensure complete combustion of the carbon to carbon dioxide, the remainder travelling' down to the molten iron where it oxidizes the carbon. The gases entering the vessel 1 may be preheated by heat exchange with the combustion gases. When gases rich in methane are used surplus heat is obtained and may be utilized by adding steam to the methanecontaining gas. The iron may be at a temperature of 1200-1300‹ C. and may contain manganese to increase the solubility of the carbon or nickel or other alloying metal which acts as a catalyst in the dissociation of methane. The ratio of gas to air used is adjusted to keep the carbon content of the iron below saturation point.

Abstract: 620,828. Keying carrier frequencies. STANDARD TELEPHONES & CABLES, Ltd. Jan. 28, 1947, No. 2601. Convention date, April 11, 1945. [Class 40 (v)] In a radio transmitter of the kind employing a keying-valve V2 connected in series with a carrier amplifier valve V1, the screen-grid and suppressor-grid of the valve V2 are supplied by means of the potentiometer P with the same D.C. voltage as the anode during the marking intervals. During spacing-intervals, the valve V2 is blocked by negative voltage applied at B to its control grid, and the fall in screen current applies a positive voltage to the grid of a valve V3 which thus forms a low-resistance shunt across the anode circuit of the carrier amplifier V1 and prevents or reduces the passing on of carrier excitation to the subsequent stages C. During marking intervals, the valve V3 is blocked by its grid being biassed negatively relatively to its cathode. Two valves of lower power, connected in parallel, may replace the valve V2.

Title: Process for the preparation of isolated living cells,cell cultures and virus cultures
IPC: C12N5/00
Filed: 1963-01-22
Abstract: Living cells are isolated from tissue of animal and vegetable origin by subjecting the tissue to the action of an enzyme, such as trypsin, and then, after a desired lapse of time, arresting the enzymatic action by a biochemical reaction in an instantaneous and irreversible fashion by introducing an inhibitor of the enzyme which forms a complex with it having no effect upon the vitality of the cells obtained. Specified inhibitors are ovomucoid, the peptidase inhibitors extracted from the pancreas, parotids or ascaris, and lima or soya beans. The cellular suspensions containing the inhibitor/enzyme complex may be used directly, without centrifuging and washing operations, for cell cultures and for virus cultivation. According to examples: (1) cortical zones of pig's liver cut into pieces, are introduced into a suspension of 0.5 g. trypsin in one litre of Hank's liquid.  The enzyme treatment is continued for five minutes at pH 7.2 and at the end of this period there is added a sufficient quantity of ovomucoid to render the whole of the enzyme inactive, viz. ten parts of an ovomucoid solution containing 0.5 g. ovomucoid per 100 ml. Hank's liquid, per 100 parts of trypsin suspension.  The yield of living cells was very satisfactory; (2) peptidase inhibitor extracted from ox pancreas replaced the ovomucoid of Example 1; (3) the cells obtained by the process of Example 1 were inoculated, after the addition of a nutritive medium, with aphthous fever virus.
