Abstract: METHOD FOR REDUCING POLLUTION DUE TO AN INTERNAL   COMBUSTION ENGINE.     ABSTRACT  OF  THE  DISCLOSURE.           The method comprises, after the end of the normal combustion of the mixture in the combustion chamber of the engine, establishing a post-combustion by maintaining a series of high-tension sparks during a long period and introducing turbulent additional air in the vicinity of said sparks so as to form a plasma which is propagated in said residual mixture.  The plasma is propagated in the cylinder from a plurality of points, that is to say partly from a point near to the spark and partly from at least another point of the combustion chamber.

Abstract: ABSTRACT      A battery operated filter blower unit is arranged to be supported on the person and has connection by a flexible conduit to face masks worn by the person, thus allowing a person wearing the filtering device to move about freely.  The filter blower unit has universal use with substantially all face masks.  For example, it can be used with a safety mask arranged to be removably suppor-ted on a head band having a front opening which is substantially perpendicular to the safety mask whereby ejected air diffuses in all directions against the mask to prevent polluted air from being drawn in around the mask.  The mask preferably in turned rearwardly at the sides as well as at the top and bottom to provide a good diffusion of air.  The filter blower unit has universal use in that it can be connected to respirator face masks of conventional use or to oxygen type face masks also of conventional use.  The filter arrangement in the blower unit is such that conventional respirator face mask filters and holders can be used.

Abstract: ABSTRACT OF THE DISCLOSURE      A controlled air incinerator having an increased capacity fox burning waste material and having increased efficiency for completely burning all burnable waste material fed there-to.  The controlled air incinerator, which is sometimes re-ferred to as a "starved air" incinerator, requires accurate control of burning conditions so as to provide at all times a discharge of clean flue gases free from pollutants.  In the present incinerator, means are provided for transferring the waste material therethrough while burning, the means causing the burning waste material to tumble within the combustion chamber and open up so as to expose to combustion air any unburned but burnable parts of the waste material whereby the oxygen of the combustion air will result in complete combustion.  The incinerator system is essentially completely automatic in that the combustion chamber of the system may be loaded without changing burning conditions in the combustion chamber and the waste material loaded therein is progressively moved through the combustion chamber while burning from the inlet end to the discharge end by transfer means, the movement of the burning waste material resulting in more complete combustion.  The system further has means for automatically discharging products of combustion, such as ash, from the outlet end of the combustion chamber without disturbing the burning conditions within the combustion chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           A wide range combustion mixture air/fuel ratio sensor in which an electrochemical cell supplies hydrogen gas to a palladium sensor element at a rate regulated by the output of a Wheatstone bridge circuit incorporating the sensor element. This generated hydrogen gas combines with any oxygen present in the exhaust gas through catalytic action and also maintains the level of absorbed hydrogen, and therefore the electrical resistance of the palladium sensor element, at a preselected value.  The magnitude of the current applied to the electro-chemical cell necessary to maintain this balance is a measure of the combustion mixture air/fuel ratio.

Abstract: ABSTRACT      Disclosed is an apparatus and its method of oper-ation for an oil well valve having a self adjusting liquid spring responsive to changes in pressure in the well annulus.  The valve has liquid spring contained in a spring chamber divided by a piston means which moves responsive to annulus pressure changes to oper-ate the valve.  The piston means includes a metering means to meter liquid from one side of the piston to the other as the volume of the liquid changes due to pressure and temperature changes.  The piston means moves responsive to pressure changes in the well annu-lus which pressure changes are applied to the well annulus at a rate faster than the metering means may relieve the changes.  A mechanical spring means in con-junction with the metering means returns the piston means to its original position after a predetermined time.  By-pass means is additionally disclosed which bypasses the metering means and may be arranged such that piston means movement occurs on either pressure increases or pressure decreases in the well annulus.

Granted: 1979-11-20
Abstract: ABSTRACT           An automatic H-register clear system for the prevention of erroneous convolution in adaptive digital echo cancellers is disclosed.  Incoming signals from the H-register are accumulated and compared to a predetermined threshold value and when the value is exceeded, the H-register is cleared with the occurrence of the internal housekeeping cycle of the echo canceller.  The clearing of the H-register allows a new impulse responsive model to be generated from new sampled data.  In one embodiment using analog implementation, the accumulation takes place using a sequence of signal processing of digital-to-analog conversion, full wave rectification followed by integration of the signal. In another preferred embodiment using a counter detection system, each word is compared to a threshold and if this value is exceeded, a counter is indexed.  If the value of the count in the counter exceeds a predetermined number during the sampling interval, the H-register is cleared.  In this latter embodiment, either analog or digital implementation can be used.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for controlling a process for the recovery of zinc from zinc sulfate electrolyte containing concentrations of impurities and addition agents.  The method and apparatus include a test circuit comprising a test cell, a sample of electrolyte, a moving cathode, an anode and a reference electrode immersed in said sample, a constant current source and measuring means electrically connected to the electrodes.  A controlled low current is applied to the electrodes in the test cell to measure the activation overpotential between the cathode and the reference electrode.  The activation overpotential is measured at the point of inchoate deposition of zinc and is related to the concentration of impurities and addition agents in the sample.          The processes for the purification of zinc sulfate electrolyte and the recovery of zinc from zinc sulfate electrolyte are subsequently adjusted in relation to the measured value of the activation overpotential to obtain optimum zinc recovery.
