Abstract: SYSTEM AND METHOD FOR PROTECTING THE        ENVIRONMENT IN A BATTERY PRODUCTION ROOM                 Abstract of the Disclosure A system is provided whereby the vapors that are given off during wet-cell battery formation are drawn directly from the batteries through openings in the cells thereof, into conduits that are readily accessible to an operator, and with the vapors further being drawn into a duct through which they may be delivered for neutralizing, for eventual discharge to atmosphere.  A novel nozzle is provided capable of introduc-tion onto the tops of any of the three different standard sized batteries during forming, which nozzles in addition to collecting vapors that are given off during wet-cell battery formation further collect a pre-selected amount of atmospheric gas for combination with said vapors, which selection reduces the explosive potential of the collected fluids during subse-quent environmentally acceptable processing.

Abstract: Abstract of the Disclosure Apparatus is provided for automatically peaking a luminance signal in a television receiver in response to the signal-to-noise ratio of a received signal.  A correction signal is derived and this is combined with the luminance signal after delaying the luminance signal.  When the signal-to-noise ratio is above a threshold value the correction signal is, in fact, subtracted from the luminance signal to increase the slope of transitions in the luminance signal.  This "peaking" increases the picture sharpness.  Below the threshold value the luminance signal is "depeaked" by adding the correc-tion signal to decrease the slope of the transitions. This overcomes the problem of prior "peaking" systems which insert an unacceptable amount of noise when the original signal-to-noise ratio is poor.

Abstract: TITLE: UNITARY SEAT FOR INNER TUBE FLOAT      Abstract of the Disclosure An inner tube seat is described for attachment to an inflated inner tube for the purpose of supporting a user above a water surface while enabling him to use his feet and legs for propulsion.  The seat is comprised of a semi-rigid elongated seat member formed with integral arcuate ends that conform to the configuration of an inflated inner tube section.  The seat member extends across the full diameter of the tube but does not span the entire central opening of the tube, thereby leaving a crescent shaped opening for access by the user's legs.  The seat member also includes forward and rearward side edges.  The forward side edge includes a smooth curved downwardly turned edge surface against which the user may rest his legs.  The rearward side edge is arcuate to conform to that portion of the inner tube engaged thereby. Intermediate the ends is a section which is recessed and shaped to conform to the user's buttocks and upper legs.  This surface is located to be well above the water level to situate the user's torso at a sufficient elevation above the water level to enable free move-ment of the arms for fishing or hunting.

Abstract: ABSTRACT OF THE DISCLOSURE                  A catalytic process is provided for cracking a hydrocarbon charge stock containing aromatic nuclei components and non-aromatic nuclei components which involves contacting such chargestock with a catalyst composition having an alkali metal content less than about 1.5 weight percent and containing a mixture of faujasite and mordenite in which contacting takes place under catalytic cracking conditions of such severity that the conversion level exceeds that attributable to conversion of the non-aromatic nuclei portion of the chargestock.  Under such conditions, the coke yield is substantially lower than would be obtained with the same catalyst in the absence of mordenite at the same level of conversion.

Abstract: J. V. Rotilio 3 FLEXIBLE CONVEYOR SYSTEM             Abstract of the Disclosure This discloses a system for lifting or conveying granu-lar, pulverized or fluid material from a first location to a second location.  A long flexible tube, open at the ends, encloses a highly flexible rotary driven helical coil spring equipped at parallel, spaced-apart positions along its length with a plurality of attachments, called "portable flights", which may comprise a shallow cylindrical cup formed from a pair of semicircular plates. The cups are secured to a succession of rungs in angularly stagger-ed relation along the length of the helical spring, and serve to pick up and convey a substantial quantity of the pulverized, granu-lar or fluid material from an input container, in which the tube is immersed, to a product chute near the top of the tube leading into a collection hopper.  As an alternative feature for granular or pulverized material, when the pile in the hopper collects above a preselected level, a metal paddle or deflection ring is deflected, operating a toggle switch, turning off the motor which rotates the helical spring.  When the pile of material falls below a given level, the toggle switch is turned on, reoperating the conveyor motor.     - i -

Granted: 1981-11-24
Abstract: ABSTRACT         The grain loading apparatus comprises the housing which is attached to the end of the grain discharge chute.          The housing includes a shutoff valve located proximately to a material outlet opening.  The shutoff valve exerts an adjustable closure force on the material flow through the outlet opening to build up a first column of material there-above.  In addition, a grain retarding cone and cylinder is arranged inside the housing above the shutoff valve.  This grain retarding cone and cylinder decreases the kinetic energy of the material flow and builds up a second column of material thereabove to significantly lessen release of dust into the air upon discharge of the grain strain.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for controlling the operation of an internal combustion engine of carburetor type, especially, the air-fuel ratio and the rate of exhaust gas recirculation, is disclosed.  The air-fuel ratio of the air-fuel mixture supplied to the engine in the steady operating condition of the engine is controlled on the basis-of predetermined data determined relative to the engine rotation speed and intake vacuum and stored previously in a memory.  A three-way catalyst is used to purify engine exhaust gases, and an output signal from an °2 sensor in the exhaust system is fed back for the control of the air-fuel ratio in the engine exhaust gases.          A circuit is provided to check whether this feedback control is normally carried or not.  The air-fuel ratio of the air-fuel mixture supplied to the engine in an unsteady operating condition of the engine is controlled by regulating the amounts of fuel and air supplied to the engine while bypassing the carburetor, on the basis of the sensed values of the intake vacuum, engine rota-tion speed and engine temperature and also on the throttle valve position.  For the control of the rate of exhaust gas recirculation, an upper limit and a lower limit of the rate of opening of a recirculation rate regulating valve are determined on the basis of the sensed throttle valve opening, and another predetermined data determined relative to the engine rotation speed and intake vacuum is read out from the memory to limit the rate of opening of the recirculation rate regulating valve.
