Abstract: METHOD FOR FEEDING REACTANT GAS TO FUEL CELLS      IN A STACK AND APPARATUS THEREFOR             ABSTRACT OF THE DISCLOSURE    A flow scheme for feeding a reactant gas to the cells of a fuel cell stack wherein the cells are connected elec-trically in series.  For example, the fuel gas is passed in parallel over a portion of each fuel electrode and thereupon into a mixing manifold which directs the exhausted gases in parallel over a different portion of each fuel electrode and thereupon into another manifold.  This is continued, depending upon the stack configuration, with the exhausted gases passing back and forth in parallel over different portions of the fuel electrodes and exhausting into a manifold until the fuel gas has covered the entire fuel electrode of each cell in the stack.  This reduces the harmful effect of a blockage within the reactant gas chamber of a cell and also reduces the harm-ful effect caused by a maldistribution of current in one of the cells in the stack.

Abstract: ABSTRACT OF THE INVENTION           An improved separator for alkaline electrochemical cells having zinc negative electrodes comprises  rare earth inorganic hydroxide in finely divided solid particulate form dispersed uniformly within a shape-retaining non-reactive matrix. The matrix may be, for example, polytetrafluoroethylene or the like and the separator is insoluble and chemically inert in the cell electrolyte. The separator traps or chemically combines with soluble zinc ions so as to keep the ions within the compart-ment containing the zinc electrode. This reduces the solubility of the zinc electrode. The resultant reduction in shape change reduces the shift in electrical properties which occurs during cycling of the cell. An improved method of making the novel separator is also provided wherein a mixture of the hydroxide and the matrix material is extruded into a thin sheet.

Abstract: ABSTRACT OF THE DISCLOSURE         A sonic transducer, having a drive electromechanical transducing element and a pickup electromechanical transducing element or a single transducing element electronically operating as both, is excited through suitable power amplifiers by a voltage controlled oscillator.  A phase comparator connected to these transducing elements detects the phase difference between stress and strain in the transducer.  Its output is connected to an integrator circuit means which integrates the phase difference signal and applies the integrated signal to control the voltage controlled oscillator.  The maximum and minimum values of the voltage which is applied to control the oscillator are independently limited by a pair of diodes connected to sources of two different voltages.  An adjustably fixable phase shift circuit is interposed between the pickup transducing element and the phase comparator to permit calibration of the system f or optimal operation.  Amplifier and clipper circuitry interposed between the phase shift circuit and the phase comparator circuit make the oscillator output signal independent of the amplitude of the vibrations of the sonic transducer.

Abstract: METHOD OF IMPROVING THE OPERATIONAL  CAPACITY OF THREE-WAY CATALYSTS                    ABSTRACT OF THE DISCLOSURE         A method is disclosed for widening the range of air-fuel ratios over which three-way catalysts having an oxygen storage capacity are operative.  Three-way catalysts are operative when new both in oxidizing at least 80% of the unburned hydrocarbons and carbon monoxide and in reducing 80% of the oxides of nitrogen contained in an exhaust gas stream delivered to the catalysts from an engine.  In general, the method is conducted by supplying to the engine to be burned therein an air-fuel mixture in which the fuel to air ratio is varied from a rich condition in which more fuel is present than air to burn it to a lean condition in which less fuel is present than air to burn it.  The air-fuel ratio is displaced equal amounts to the rich and to the lean sides from a stoichiometric condition.          The displacement to each side is generally of an identical nature and the overall frequency of displacement is such that the oxygen storage capacity of the particular three-way catalyst is not exhausted during the lean portion of the cycle.

Abstract: ABSTRACT OF THE DISCLOSURE              A keyable control circuit, has sensing coils located in the vicinity of a plurality of locations where lock control is desired.       At least one swept high-frequency oscillator, which is connected to each sensing coil, generates an rf signal, rapidly swept over a wide frequency band.  When an external keying circuit, containing more than one resonant circuit, each correctly tuned to a predeter-mined keying frequency, is inductively coupled to a sensing coil, each resonant circuit absorbs rf energy as the oscillator frequency 18 swept past its resonant frequency.  Energy absorption in the external keying circuit induces corresponding reductions in rf energy in the sensing coil as the oscillator frequency is swept past the keying frequencies.  Tuned detectors within the keyable control circuit produce a control signal when energy reduction is sensed at each of the predetermined keying frequencies.  If correct absorption fails to occur at any one or more of the predetermined frequencies, the control signal is withheld.

Abstract: Abstract of the Disclosure A tone signal detector comprises a clock signal generator for generating clock signals of a frequency equal to N times (where N is an integer) the frequency of the tone signals detected.  An N-path filter selects the tone signals according to the output of the clock generator.  A low-pass filter connected to the output of the N-path filter eliminates the frequency component of the clock signals.  A wave shaping circuit shapes the signals passed by the low-pass filter.  A gate circuit controls the clock signals in accordance with the output of the wave shaping circuit.  A counter counts the number of the output pulses provided by the gate circuit.  A timing circuit determines the count of the counter in a prescribed period of time thereby establishing whether or not the tone signals are the designated ones.
