Title: Fuel cell units for power supply
IPC: H01M8/08
Filed: 1972-06-09
Abstract: 1363999 Fuel cell power units SIEMENS AG 9 June 1972 [11 June 1971] 27181/72 Heading H1B An electric power supply unit 10 consisting of a fuel cell battery and its auxiliaries comprises a housing having arranged sequentially therein: a control chamber 11, a supply reservoir 12 for liquid electrolyte, a cooler 13, a pressure lock 14, an electrolyte regenerator 15 and two fuel cell batteries 16, 17. The fuel cell reactants, hydrogen and oxygen, are supplied at inlets 18, 19. Unconsumed gas or gaseous products leave the unit at outlet 20. Water of reaction produced during operation of the batteries 16, 17 may be discharged at outlet 23. Coolant water for the cooler 13 is supplied at 21 and leaves at 22. An electromagnetic valve 24 determines whether the water of reaction extracted from the electrolyte and transported into the pressure lock 14 is either discharged through lines 37, 23 or is returned to the reservoir 12 through lines 37, 25, the valve being controlled by sensors 38, 39 which sense, respectively, the concentration and temperature of the electrolyte in the reservoir. The electrolyte is circulated by a pump 26 from the reservoir 12 through a duct 27 which divides into two ducts 28, 29 and then flows in parallel lines 30 through the batteries 16, 17. The two ducts 31, 32 from the batteries connect into a duct 33 and the electrolyte then flows in parallel paths 35 through the regenerator 15, where the water of reaction is condensed, and through the cooler 13, the electrolyte returning by a duct 36 to the reservoir 12. The water of reaction is transported from the regenerator 15 to the pressure lock 14 by a pressure gas line 57, Fig. 2, connected to the hydrogen inlet 18 through a line 54, manually operated valve 53, electromagnetic valve 55 and a reducing valve 56. In the pressure lock 14 the water of reaction is forced by gas pressure through a liquidpermeable asbestos diaphragm into a liquid chamber and thence passes to the line 37. The oxygen and hydrogen reactants are fed, respectively, to the batteries 16, 17 through lines 52, 66 and 51, 65 controlled by gas-pressure operated valves 59, 58, the unit being started by closing valve 53 manually. At a predetermined pressure in control lines 60, 61 the valves 58, 59 open, a throttle 62 causing delayed opening of oxygen valve 59. When the voltage of the batteries reaches a perdetermined value the valve 55 opens so that valve 53 may be released and the unit then functions automatically. The gas return lines 67, 68 controlled by valves 63, 64 discharge their products through reservoir 12 to remove liquid entrained therein before discharge at outlet 20.

Abstract: 1473787 Active filters HAZELTINE CORP 2 July 1975 [18 July 1974] 27801/75 Heading H3U  An adaptive filter for suppressing an interferring narrow band signal in a composite signal containing a desired broadband signal comprises: a signal combiner 22; means 18 for supplying a composite input signal to the combiner; means 16a for delaying the input signal; and means 26, 28, 30, 34 responsive to the delayed signal and the output from the combiner for supplying a correction signal to suppress the interferring narrow band signal. In the embodiment of Fig. 1, the filter also frequency changes the signal, and includes frequency changers 18, 26a, 30a. The unwanted signal produces correlated inputs to frequency changer 30a and the resulting output is integrated at 34a to provide an input to frequency changer 26a which is mixed with the other input to provide a signal to combiner 22 to cancel the unwanted signal. The wanted signals do not provide correlated inputs to 30a and hence no signal is applied to 26a from integrator 34a and no correction signal is produced at the output of 26a. A further stage 16b, 26b, 28b, 30b, 34b may be cascaded with the first to provide a further input to combiner 22. In a second embodiment Fig. 4 (not shown) further stages are connected in parallel instead of cascade and the integrator is replaced by a filter, Fig. 5 (not shown), which comprises two parallel connected frequency changing paths fed with quadrature reference signals. In a further embodiment not utilizing frequency changing, Fig. 6 (not shown) the output of the delay device 16 is fed to the combiner 22 via a network which adjusts the phase and amplitude of the signal independence on the combiner output.

Title: Improved method of and apparatus for the metering of gaseous fluids
IPC: G01F1/7088
Filed: 1929-09-13
Abstract: 331,439. Humphreys & Glasgow, Ltd., (Assignees of Blake, A. E.). Oct. 18, 1928, [Convenfion date]. Gas meters.-The gas to be measured is ionized as by exposure to radiations from radioactive substance 2, and the electric current between the tube of flow 1 and the electrode 3, or other two electrodes placed in its line of flow, is measured and may be recorded by suitable means. The rate of flow determines the number of ions which reach the gap 4, and therefore the current across the gap. In the form shown, the gap is connected across the plate and grid of a three-electrode valve 6, and has a potential difference applied by batteries 8 and 9, the battery 8 also giving negative grid bias through a resistance 10. When the gap becomes conducting and a current flows, there wilt be a fall in potential across the resistance 10, reducing the negative grid bias and allowing a flow of current to the plate of the valve. The resultant current is measured by the ammeter 11, which is a recording or integrating instrument calibrated to measure gas volumes.
