A brace interconnects the pedestal and the base intermediate their ends securing the pedestal at its inclined orientation relative to the base. The stand is collapsible for storage to minimum dimensions with all of the components securable against displacement.

Abstract: A weight transfer system for coupling a two-way gang plow to a towing vehicle eliminates lifting of the rear end of the towing vehicle due to the weight of the plow assembly when the plow assembly is raised for transportation. An elongated cable is connected at its forward end to the tow bar of the towing vehicle, at a pivot point above and coaxial with the pivot towing connection of the plow tongue, and at its rearward end to the main support frame at a point above the point of joinder of the main support frame and a pivoting linkage which connects the main support frame to the wheel of the plow. A hydraulic cylinder rotates the linkage to raise the main support frame, thereby tensioning the cable and rotating the support frame angularly upward for towing. The tension force in the cable in turn causes a moment at the tow bar counteracting the lifting force at the rear end of the towing vehicle caused by the weight of the plow assembly.

Abstract: A dispensing apparatus for toilet tissue includes first roll maintaining fingers for holding a first roll of tissue rotatably in an operative position partially extending through a window in the frame of the apparatus. Second roll maintaining fingers engage a second roll of tissue and support it and subsequent rolls above the first roll. An escapement mechanism operable by the user engages the first and second roll maintaining fingers for moving them from a closed, roll-engaging position to an open position disengaging the rolls, causing ejection of the core of the empty first roll and depositing the second roll in the window for use. Third roll maintaining fingers are engaged by the escapement mechanism in a manner to be placed in engagement with a third roll, securing it and subsequent rolls while the second roll is being transferred to the operative position of the ejected empty first roll.

Abstract: In a plow assembly, each plow bottom is supported by an arm mounted pivotally on a beam for movement of the plow bottom between outwardly extending and inwardly retracted positions. The beam and each arm are operatively interconnected by an extensible fluid pressure piston-cylinder unit supplied at one end with fluid under pressure, whereby the plow bottom is urged toward said outwardly extending position. The opposite end of the piston-cylinder unit communicates with a sealed chamber containing air or other compressible gas to prevent entrance into the cylinder of air laden with dust and other debris. In a two-way plow assembly, the arms of each opposed pair are interconnected by the fluid pressure piston-cylinder unit, and abutment means interengages each arm and the beam to limit the degree of outward extension of the plow bottoms.

Abstract: A football is projected with rotation on its longitudinal axis, in the manner of a forward pass, when it is fed into the space between, and thereby gripped frictionally by, the laterally spaced, confronting surfaces of a pair of driven wheels which confronting surfaces move in a forward, football throwing direction but in planes which extend forward angularly to opposite sides of the line on which the football is projected, the planes forming an included acute angle with each other. The speed and direction of football rotation may be varied by adjusting said angular relationship, and the speed of forward projection of the football may be varied by adjusting the rotational speed of the wheels. By adjusting said confronting surfaces to a common plane and feeding a football into the space therebetween such that said surfaces grip the football below its longitudinal centerline, the football is projected therefrom with rotation on its transverse axis, in the manner of an end-over-end kick-off.

Abstract: A sludge incinerator for use in the flash evaporation of water contained in high moisture sludges comprises a primary chamber, with longitudinally spaced inlet tubes to introduce the sludge and compressed air therein in an atomized spray, and primary burners intermediate the inlet tubes, to heat and burn the sludge, thus separating it into dry solids and water vapor. A screw conveyor removes the dry solids from the primary chamber. An afterburner, including secondary burners, a secondary air supply, and a mixing chamber to mix the secondary air with the primary combustion products, provides further oxidation to achieve substantially complete combustion of the combustibles content of the sludge and fuel. A vertical stack exhausts these combustibles and vapors from the mixing chamber.

Abstract: A charcoal lighter comprises a tubular housing with draft openings in the lower portion and a grate loosely positioned within. Hanger rods pivotably support the grate removably from the upper edge of the housing in a raised, horizontal position for holding charcoal to be lit, and one of the rods is releasable from the housing edge to pivot the grate to a lowered, declining position for depositing the lit charcoal onto a grill base. A perforate plate is installable on the upper edge of the tubular housing, allowing its use as a miniature grill, and when so installed it locks the releasable hanger rod to the housing edge, to prevent inadvertent release of the grate to the lowered position.

Abstract: A power amplifier for use in uni-directional telephone line signal amplification requirements on voice and data grade circuits includes a balanced input transformer and associated differential line transient protection circuit and line matching network, a balanced differential voltage feedback amplifier circuit with externally interchangeable, balanced, passive, terminated attenuators in the voltage feedback path for varying the amplification factor of the signal amplifying circuit, a balanced-to-unbalanced common mode rejection circuit, low and high cut frequency filters, and a balanced output transformer with associated output line matching and circuit protection components. The interchangeable attenuators are calibrated and marked in terms of overall power amplification resulting from their individual and specific use in the circuit.

Abstract: A tank carrier for releasably mounting an anhydrous ammonia tank on a farm tractor includes a pair of relatively movable tank support members by which a tank is raised from the ground and held firmly against lateral displacement. In one form of the invention one of the support members of the pair comprises a pair of laterally spaced fluid pressure cylinders arranged to engage and elevate a tank from the ground, and the other support member of the pair comprises a pair of plates having contoured edges matching the confronting periphery of the tank.

Abstract: Quadraphonically encoded left end right signals are fed to separate left and right signal phase shifters the outputs of which are fed to three variable gain amplifiers for each of the four corner loudspeakers of a quadraphonic playback system and also to three comparators which function to control operation of the variable gain amplifiers in such manner as to cancel cross talk by altering the decoding coefficients of the cross talk bearing channels.

Abstract: Logs to be sorted according to species, grade, length, diameter and a variety of other characteristics and parameters, are delivered one at a time crosswise to the infeed end of an elongated conveyor assembly formed of a plurality of longitudinally aligned, transversely articulated conveyors. A retractable stop is associated with the downstream end of each conveyor for releasable abutment by the logs as they progress along the conveyor assembly. Upon such abutment and subsequent tilting of the conveyor, the log thereon is lowered onto a registering transfer conveyor extending laterally thereof. At the outfeed end of the transfer conveyor the log is directed into a sort rack. When the latter has been filled with a plurality of like logs, they are removed as a group for subsequent processing.

Abstract: A pair of hull portions connected in spaced parallel relation support a water wheel and form a passageway therebetween for driving engagement of flowing water against the vanes of the water wheel. The water wheel is made up of a pair of wheel portions having peripheral gear teeth, and these teeth are engageable with gears which drive electric generators. The vanes of the water wheel are adjustable to vary the driving power thereof and have nozzles thereon arranged to discharge water under pressure to provide a boost for the wheel. A brake is provided to control rotation of the water wheel, and an auxiliary engine is provided to drive the water wheel when necessary. The longitudinal hull portions support a gate mechanism at the inlet end of the water passageway to control the flow of water through such passageway and have air chambers to buoyantly support the device. The device has vertically extendable legs for ground support.

Abstract: Kernels of grain or other particulate harvester product, trapped with chaff and other trash being returned to the ground, are caused to drop onto an impact-sensitive transducer which thereupon produces corresponding electric signals which are counted and related to harvester ground speed and header width to provide a read-out of quantity per area of particulate product lost.
