Title: An electrolytic process for regenerating iron sulphate mordants
IPC: C23G1/36
Filed: 1961-11-24
Abstract: <PICT:0940517/C3/1> Acid pickle containing H2 SO4 and ferrous sulphate, is regenerated by (a) crystallizing the crude pickle and re-dissolving the ferrous sulphate so obtained to form a substantially neutral solution which is then (b) admitted as catholyte in a three compartment cell formed by diaphragms, the central compartment preventing drift of H ions from anolyte to catholyte which is maintained at pH of 3 by regulating the flow, (c) passing a current to deposit iron on the cathode, the sulphuric acid formed passing to the central compartment with some ferrous sulphate, which is then drawn off, and recycled to the pickle supply, preferably after removing some at least of the ferrous sulphate. In a suitable apparatus, pickle liquor is continuously circulated from a tank 1 through a heater 3, and a part is injected into a sprinkling tower 4 against a current of cold air, which takes off some water. The concentrated liquor is further cooled in a vessel 7, from which the centrifuged discharged liquor returns to the tank 1 and the separated ferrous sulphate is fed into a catholyte mixing vessel 11. "Weak pickle acid" containing 20 to 30 g. H2 SO4 per litre is added from a tank 19, and the acid ferrous sulphate solution is "neutralized" by scrap iron in a vessel 12.  The restulting catholyte containing 150 g. of iron or more per litre, is fed into compartment 14 of the electrolytic cell, and is maintained at 50 DEG  to 70 DEG C., where some iron is deposited on the cathode 15, and the solution passes to the central compartment 17 where it is admixed with H ions from the anode compartment 18.  This "weak pickle acid" is fed into the tank 19 and kept hot by circulation through a heater 21. Sulphate ions accumulate in the anode compartment and the regenerated acid passes to the cooling vessel 7. In an alternative process, where the ferrous sulphate separated in the centrifuge is not too acid the treatment with scrap iron is omitted, and the acid from the central compartment 17 of the cell is fed directly to the cooling vessel 7.

Title: Measuring apparatus
IPC: G01R15/09
Filed: 1969-08-27
Abstract: 1,263,798. Measuring apparatus. INTERNATIONAL BUSINESS MACHINES CORP. Aug. 27, 1969 [Sept. 5, 1968], No.42566/69. Heading G1U. A signal pulse having a time duration which is a function of a parameter to be measured e.g. the time delay in circuit 10, is applied to the common input of a number of sensor circuits each of which defines a different time duration range and supplies an output signal having an amplitude related to the duration of the input signal to a threshold detector which controls logic circuitry whereby the output signal of the sensor in which the pulse duration is nearest to but does not exceed the maximum of its range is selected and with an indication of the range provides a measure of the parameter. The output can be digitalized in A/D converter 47. Each sensor circuit 26-28 includes a capacitor charge circuit arranged such that the linear portion of the charge characteristic extends over a different time period e. g. 0-10, 0-100, 0-1000 nano-secs and is associated with a threshold detector which supplies an output "1" when its associated sensor capacitor is charged beyond its linear portion. Thus assuming a pulse input duration falls in the mid-position of the second range, the linear portion of range 1 is exceeded so that threshold detector 35 produces a "1" output which prevents chopper 36 operating and when inverted in driver 48 fails to actuate the range I indication. Detectors 37 and 39 both produce "O" outputs but the output of detector 37 when inverted in unit 52 provides a "1" to block output indication from the range III circuits. Thus detector 37 provides a "O" which when inverted in unit 51 actuates the range II indication and allows the sensor 27 output signal to pass via chopper 38 and amplifier 46 to A/D converter 47. The converter output and the range indication provide a measure of the pulse duration and hence the parameter being measured.

Filed: 1965-10-08
Abstract: 1,157,962. Ventilating aircraft. PLESSEY CO. Ltd. 28 Sept., 1966 [8 Oct., 1965], No. 42738/65. Heading F4V. [Also in Division F1] The invention relates to an air supply system in which air is tapped for example from two different points of a compressor of a gas turbine engine for use for aircraft cabin pressurization. The air tapped from one point of the compressor is at a pressure greater than the required air pressure and that tapped from the other point is at a pressure less than the required air pressure. The air at the higher pressure is passed to an air turbine while that at the lower pressure is supplied to an air compressor driven by the air turbine, the air discharging from the turbine and that discharging from the compressor being mixed and thence supplied to the point of use. In the embodiment shown a chamber 5 is provided and an assembly comprising a rotor 1 and shaft 2 is rotatably mounted therein. The rotor 1 comprises a centrifugal air compressor 3 and an air turbine 10. High pressure air tapped from the engine compressor is supplied through line 7 and passes by way of a control unit 8 through lines 13 to nozzles 9 which direct it on to the air turbine. Lower pressure air tapped from the engine compressor passes through duct 4 to the air compressor 3, the air delivered by the compressor and that discharged from the turbine mixing in the chamber 5 and then passing through line 6 to the point of use. The control system for the turbine comprises a piston 11 disposed in a cylinder 12 the axial position of the piston determining the number of lines 13 and hence turbine inlet nozzles 9 through which high pressure air may flow. The piston 11 is connected to a piston 14 disposed in a cylinder 15, the piston 14 being subject at its right-hand side to pressure of the high pressure air in line 7 so that the pistons 11 and 14 are pressure balanced. The rod connecting the pistons 11 and 14 is connected to a control piston 16 disposed within a cylinder 17, one side of the piston being subject to ambient pressure and the other side being subject to pressure within the chamber 5. The excess of chamber pressure over atmospheric pressure thus tends to move the piston 11 to the left against the loading of spring 18, so as to cut off the number of turbine nozzles 9, so that less air is tapped through the line 7 and the power of the turbine 10 is reduced. Thus the pressure within the chamber 5 and so the air supplied to the cabin is reduced.
