Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is a marine propulsion device and apparatus and methods for assisting trans-mission shifting thereof.  The marine propulsion device includes an internal combustion engine and a reversing transmission having a pair of bevel gears and a clutch dog movable between a neutral position out of engagement with the bevel gears and forward and reverse drive positions in full engagement with one of the bevel gears. The marine propulsion device also includes a shift assistance arrangement included in a shift mechanism for axially moving the clutch dog between the neutral and drive positions, and which includes a load sensing lost motion shift lever arrangement having a first switch which is actuated when the resistance to axially moving the clutch dog into a drive position exceeds an upper limit.  The shift assistance arrangement also includes an ignition interruption circuit responsive to actuation of the first switch for selectively interrupting the ignition of the internal combustion engine to reduce the engine torque transmitted to the bevel gears to effect relative angular displacement of the clutch dog and the bevel gears to thereby assist the shift mechanism in moving the clutch dog into and out of a drive position.  The ignition interruption circuit includes a control circuit having a first timer for providing a plurality of successive timed cycles, each cycle including an ignition-kill interval and an ignition-on interval, and also having a second timer for estab-lishing an overall cycle during which the first timer is operative, subject to the first switch.

Abstract: Abstract of the Disclosure A dead plate for use in apparatus for transferring elongated articles into the product buckets of a cartoner.          The articles are conveyed single file and are diverted by a primary diverter into two diverter conveyors.  The articles are thereafter pushed from the diverter conveyors into left and right accumulator stations onto conveyors moving trans-versely in opposite directions.  The accumulator conveyors hold the articles side-by-side at the downstream end of the accumulator conveyors.  A pusher bar pushes a group of articles from their ends longitudinally off the accumulator conveyor onto the  dead plate which overlies the cartoner product bucket conveyor.  A sweep bar sweeps the articles off the dead plate into the product buckets.  The dead plate has a finger which projects alongside of the dead plate over which the ends of the articles ride so as to cause the articles to drop into the product buckets one end at a time, thereby providing better control over the position and orientation of the articles in the product buckets.

Abstract: EARTH BORING BIT WITH ECCENTRICALLY       FORMED BEARING SURFACE        Abstract of the Disclosure A rolling cone cutter earth boring bit is provided with an improved bearing system including a hardmetal bearing surface and a space for lubricant.  At least one cantilevered bearing pin extends from the arm of the bit.  A rolling cone cutter is rotatably mounted on the bearing pin.  The primary bearing surface of the bear-ing pin is provided by forming a groove in the lower bear-ing surface of the bearing pin and filling a portion of the groove with bearing material to form the load carrying portion of the bearing pin.  The groove is eccentric to the bearing pin central axis.  Bearing material is applied in the groove and is machined to coincide with the bearing pin surface on the load side.  Part of the groove is left unfilled.  The unfilled portion of groove serves as a lubricant reservoir in close proximity to the load side of the bearing pin.

Abstract: LIFT ARM WITH IMPROVED CHAIN CONNECTOR        Abstract of the Disclosure An improved lift arm is pivoted upward by a hydraulic cylinder to lift a plow blade by a chain connected between the lift arm and blade.  The lift arm includes an elongated body with a chain receiving member permanently fixed to an end thereof.  Engaging a link of the chain is a slot in an up-wardly facing concave surface of the chain receiving member. The slot has a width slightly greater than the thickness of a link of the chain so that a link is engaged and restrained. An opening, having a width slightly greater than the width of the link, receives the chain ahead of the link restrained in the slot.  Regardless of the relative orientation of the chain and lift arm, the concave surface causes the chain and chain receiving member to remain generally perpendicular.

Abstract: REMOTELY CONTROLLED SERVO DEVICE FOR CONTROLLING FLUID FLOW     ABSTRACT           A control device, typically for carburetors, in which there is utilized a permanent magnet armature, a pair of coils surrounding the permanent magnet, and a microproces-sor responsive to certain parameter-sensed variables includ-ing pressure, temperature, throttle conditions, and oxygen content in order that these variously sensed parameters can be communicated to the microprocessor wherein there is transduced by algorithm either a digital signal or an analog signal.  Either signal is then communicated in the form of a demand for current flow to the coil.  The coils upon energi-zation mechanically displace the armature to effect mechanical transducing of the electrical signal to control an actuator rod with an orifice control at the end of the actuator rod.          The armature effectively controls an orifice size which in turn determines fuel/air ratio for an internal combustion engine, in conjunction with a carburetor function.  Fuel-air control creates operating conditions which in turn are re-sensed by the sensors, the sensors in turn repeating their operation so that there is a closed loop servo system either by digital or analog signals as aforedescribed.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of burning a sulfur-containing fuel in a fluidized bed of sulfur oxide sorbent wherein the overall utilization of sulfur oxide sorbent is increased by comminuting the bed drain solids to a smaller average particle size, preferably on the order of 50 microns, and reinjecting the comminuted bed drain solids into the bed.  In comminuting the bed drain solids, particles of spent sulfur sorbent contained therein are fractured thereby exposing unreacted sorbent surface.  Upon reinjecting the comminuted bed drain solids into the bed, the newly-exposed unreacted sorbent surface is available for sulfur oxide sorption, thereby increasing overall sorbent utilization.

Abstract: A B S T R A C T The invention relates to a surface covering product suitable for use in the furniture and construction industry, and to a process and apparatus for its production.  The essence of the process is that a band is formed from ven-eer and is softened by wetting or with ammonia, and than treated with a fire-retardant agent.  Then thermoplastic synthetic adhesive is preferably applied between the veneer band and a carrier material by rolling, pouring, or spread-ing.  Furthermore the so-prepared veneer is guided onto the carrier surface of a strip or lath shaped carrier body extruded from synthetic material, and sub-jected to the effect of pressure rollers and/or an oscillating pulsator in a closed space provided with a heat and pressure transmitting stamp with a nega-tive surface, while the temperature of the air, flow velocity and relative water content are regulated in the closed space.  In this way removal of the heat of the adhesive is accelerated to such extent, that the heat and solvent do not reduce the strength of the carrier surface of the extruded synthetic carrier body to be covered and thus adhesion of the veneer to the surface of the carrier body to be covered is ensured during continuous progress without deformation of the synthetic carrier material.
