Abstract: Abstract A fuel-water separator comprises a container having entry and exit ports and a progression of spaces through which the fuel moves.  The spaces become progressively smaller and are arranged to direct the fuel through a series of downwardly and upwardly directed paths.  The lower density fuel moves upwardly while the higher density water tends to move downwardly to drain through drainage openings provided in the lower portions of the spaces.  Valves are provided for closing the drainage openings.  The valves include float-valve balls which will release the water but hold the fuel. One of the spaces in the container includes a media having a downwardly directed surface upon which the water coalesces to move downwardly and through which the fuel moves to progress to the next space.  Another one of the spaces includes a media providing a surface tension-discriminating surface through which the fuel will move and down which the separated water will move. The fuel entering the separator may move first through a generally circular passageway having a radially outer wall with openings through which the water is separated by centrifugal force.

Abstract: Abstract Improved radio transmitter modulation control circuitry is described which significantly increases the average power of the modulating signal, resulting in enhanced audio signal quality since the signal-to-noise ratio is likewise increased.  The inventive modulation control circuitry includes a microphone 110, audio amplifer 120, splatter filter 130, modulator 150, potentiometer 140, oscillator and transmitter 180, and antenna 190.  The audio amplifier 120 further includes an operational amplifier 160 having an input resistor 162 coupled via capacitor 168 to microphone 110, a phase-lag filter 170 coupled to the output of the operational amplifier 160, and a feedback resistor 161 coupled between the filter 170 and the input resistor 162.  When driven into amplitude limiting, the phase and amplitude of harmonic signals from the operational amplifier 160 are altered by phase-lag filter 170 to produce a waveform similar to that shown in Fig. 2.  When operated linearly, the audio amplifier 120 has a flat frequency response, the filter 170 having no effect since it is in the feedback loop.  The improved modulation control circuitry of the present invention can be advantageously utilized in both amplitude and frequency modulated radios 100 for enhancing the audio signal quality thereof.

Abstract: PAPERBOARD CARTON             Abstract of the Invention A one-piece T-shaped carton blank is disclosed which is utilized to form a rectangular cross-sectional container having its top and bottom end panels sealed in a plane substantially perpendicular to its sidewalls.  The carton blank is formed having a definite dimensional relationship between its end panels and side panels to provide improved nesting of multiple carton blanks upon paperboard sheet stock in an alternating inverted side-by-side relationship.  A pair of end sealing tabs extend along the top and bottom edges of the blank side panels,  One of the end sealing tabs is separated from the top end panel and from a side sealing tab to prevent tearing and to permit the complete welding of the side sealing tab up onto the top end closure panel of the carton blank.  This separation of the end sealing tab in combination with displacement of the hinge line of the top end closure panel downward provides a liquid-tight corner seal for the carton.  Further, an improved method of scoring and bending of the carton blank is provided.

Abstract: ABSTRACT OF THE DISCLOSURE         A change-speed apparatus in a tractor equipped with an engine has a planetary gearing mechanism settable between its two positions.  Actuation of the mechanism to one of the two posi-tions is hydraulically power-actuated, while actuation to the other of the two positions is automatically effected, as the hydraulic power is released, by a spring.  Power-transmitting oper-ative connection is therefore always maintained between the engine and running-drive wheels, even when the hydraulic actuation power falls to zero.

Abstract: ABSTRACT OF THE DISCLOSURE      An exhaust gas recirculation valve driven by an electric motor.  The valve comprises a housing having an inlet port and an outlet port, a valve member disposed within said housing, an electric motor attached to the upper portion of said housing, a changing means for changing the rotation of said electric motor into the vertical movement of said valve member, said changing means being disposed between the shaft of said electric motor and a valve rod.          The valve member is operated by said electric motor through the intermediary of said changing means.  Therefore, the valve can be controlled delicately independent of the engine manifold vacuum.  The valve may be incorporated into an electronic fuel injection system adapted to calculate the amount of fuel supply to an internal combustion engine by means of a control unit so as to obtain an optimum air-fuel mixture or air-fuel ratio.  In this case, an actuating signal calculated on the basis of said amount of fuel supply and the information of sensors is given to said electric motor so as to obtain an optimum opening of the valve.          Therefore, the valve can be controlled very accurately.

Abstract: ABSTRACT OF THE DISCLOSURE A valve seal for a butterfly valve comprises a U-shaped annular seating member disposed in an annular slot in the valve body and a retaining ring for holding the seating member in place.  The seating member cross-section comprises two legs and a bight portion connecting them.  A first one of the legs is captured between the retaining ring and valve body to hold the seating member in the slot and enable limited rotational movement of the seating member.  A radially inwardly projecting extension on the bight terminates in an annular sealing surface that cooperates with the valve disc.  The seating member divides the slot into first and second axial sides in fluid pressure communication with the valve chamber.  The seal also comprises an annular open-helical back-up member disposed in an annular cavity formed in the slot by the legs and bight portion of the seating member.  The annular cavity is in fluid pressure communication with the second axial side of the slot. The back-up member resists cross-sectional compression and creates an expansive reaction force in a direction perpendicular to a cross-sectional compressive force. This arrangement provides effective sealing for system pressure from either side of the seal.  The retaining ring is held to the valve body by attachment means comprising a plurality of radially extending threaded holes through the valve body and a plurality of conical blind holes in the retaining ring, each aligned with a threaded hole.  A screw with a conical end is accepted in each threaded hole and cooperates with the blind holes to urge the retaining ring axially toward the valve body. DMQ:rb April 22, 1981

Abstract: Abstract An assembly on an agricultural implement, especially a semi-plow, comprises a plurality of pivotable and mutually interacting parallelograms and a plurality of partially interconnected link members which regulate the implement's support wheel and a turn limiter.  The turn limiter is automatically regulated when the implement is being adjusted to adapt it to the tractor track as well as to the desired plow strip width so that the maximum angle of deflection, to the right or to the left, between the tractor and the turn limiter is held constant no matter what the angle assumed by the implement in relation to the driving direction.  The turn limiter thus prevents the tractor from abutting against the implement when the tractor turns sharply, while at the same time the wheel is automatically correctly adjusted when the implement is being adjusted to adapt it to the tractor track and the desired plow strip width, whether the implement is driving in a straight line or on a curved path.
