Title: Apparatus for measuring the content of dust in gases
IPC: G01N15/00
Filed: 1975-02-12
Abstract: 1494451 Determination of dust content in gas F L SMIDTH & CO A/S 12 Feb 1975 5970/75 Heading G1B [Also in Division B1] Apparatus for measuring the content of dust in a gas, e.g. smoke, comprises a nozzle 1 connected to an exhaust device, e.g. an ejector 4, to suck in a sample of gas 68 flowing in a duct in which the nozzle is positioned; a filter housing 2 containing filter means to separate dust from the gas and connected to the nozzle by means of a connecting tube 3; a source of heat transfer medium, e.g. compressed air, and means to deliver it to a passage provided in the connecting tube 3 for heat exchange with the gas sample flowing therein; and means for controlling the temperature of the heat transfer medium between the source and the connecting tube 3, the means comprising controllable heating means. If it is necessary to heat the gas sample to prevent condensation in the sampling apparatus, then this may be done by applying heat to the heat transfer medium. If it is necessary to cool the gas sample, then the heating means may be switched off and cold heat transfer medium supplied. The heating means and rate of heat transfer medium supply may be controlled in response to the gas temperature downstream of the filter as measured by probe 80. The heating means may also control the temperature of the filter housing. Means, e.g. manometers 15, 15a are provided to measure pressure drop across an apertured disc in the filter housing and also the pressure in the housing to enable the amount of gas passing through the housing to be calculated. Also, the apparatus comprises means, e.g. manometers 63, 69, 71 connected to inlet nozzle 1 and to the duct interior, to measure the static pressure inside and outside the nozzle and the velocity pressure of gas entering the nozzle to enable positioning of the nozzle so that gas entering has an identical velocity to that passing the nozzle in the duct and to enable calculation of the amount of gas passing the duct.

Title: Improvements in or relating to mass spectrometers
IPC: H01J49/34
Filed: 1963-02-18
Abstract: 1,005,053. Mass spectrometers. MAXPLANCK GES. ZUR FORDERUNG DER WISSENSCHAFTEN e.v. Feb. 18, 1963 [Feb. 22, 1962], No. 6388/63. Heading H1D. In a mass spectrometer of the type in which a beam of ions is projected from an ion source 107 along the axis 106 by a longitudinally extending vacuum tube into a potential well formed by positive end electrodes 101, 105 and intermediate negative electrodes 102, 103, 104, effectively only selected ions being caused to oscillate in the potential well, one end electrode 101 or 105 only is biased to a positive potential, while the other end electrode is periodically raised by means of pulses to a positive potential, or both end electrodes are pulsed periodically to positive potentials either jointly or in anti-phase. The selected ions are detected at electrode 103 or at one of the end electrodes. The ion source may be worked continuously or periodically. Unwanted ions are discharged at the envelope wall and to aid their removal from the potential well region the pulse widths of the potentials periodically applied to the end electrodes may be reduced, or an additional short negative potential pulse may be applied to the end electrode 105, which pulse may be of sufficient magnitude to drive the selected ions through end electrode 101 to an electron multiplier. In this case the electron stream of the ion source 107 is directed perpendicularly across the tube axis. Unwanted hydrocarbon ions may be decomposed inside the tube by means of an electron beam or a hot tungsten wire. The electron emitting ion source 107 may be replaced by a plasma ion source. An annular auxiliary electrode 115 is provided to ensure that newly formed ions in a pulsed ion source are all released at the same time. Interference signals due to the potential pulses applied to the pulsed electrodes may be eliminated by including a compensating electrode to which the pulses are applied in antiphase, or the ion source may be modulated with a low frequency signal so that the wanted signal can be recognized by its modulation, and isolated. The ions may be focused by an axial steady magnetic field and selectivity may be improved by including a magnetic ion optical system or a quadruple Paul-type field system. The spectrometer is particularly suitable for leakage detection
