Abstract: TITLE OF THE INVENTION           Controlled Sludge Composting System ABSTRACT OF THE DISCLOSURE        The invention is a controlled system for composting sludge to a useable state.  The method of the system eliminates the usual objectionable odors.  The system consists of a thorough mixing of the sludge with carbonaceous material, layering the mixture in a silo and moving it through the silo on a timed interval basis, forcing air through the mixture in the silo to promote the composting action by an aerobic bacteria pro-cess, periodically withdrawing the treated material in a manner compatible with the timed interval basis, further layering the composted material in a second silo having a forced air means to complete the treatment process, and with-drawing the final treated material for packaged or for bulk distribution to users.

Abstract: ABSTRACT OF THE DISCLOSURE     To provide measurement of horizontal and vertical spatial errors, as well as shading errors, the active video picture is divided horizontally into 13 equal blocks, and vertically into 14 bands of checkers.  During the setup mode, the signal from a selected camera is fed to an A/D converter in the video signal path, and to sync and pattern validation circuits which provide control and timing signals and an electronic test pattern.  Horizontal error measure-ment is provided via a horizontal adder/memory loop whereby selected samples within the blocks of successive horizontal lines are selectively summed to provide successive pairs of summed horizontal digital data.  Vertical error measurement is done simultaneously by a vertical adder/memory circuit whereby selected adjacent samples of alternate checkers are selectively delayed and added, to provide successive pairs of summed vertical digital data.  During a read cycle, the horizontal and vertical pairs of digital data are selec-tively subtracted to inherently cancel the effects of existing shading errors, blooming, crosstalk, etc., and the difference signals are D/A converted. The horizontal and vertical transition and zero crossing information is estab-lished, and the transitions are compared with the electronic test pattern to derive the digital horizontal and vertical spatial error data for storage in a microprocessor memory.          Shading error data are provided from the vertical adder/ memory circuit and also are stored in the microprocessor memory.  The stored error data are subsequently retrieved and used to provide spatial and shading correction during the camera operating mode.

Terrain in front and to the sides of the vehicle may be viewed by a driver from within the vehicle by a plurality of periscopes.  Alternatively, a hatch opening in a forward sloping surface of the nose immediately be-hind the periscopes permits the driver to raise his head out of the vehicle in order to view the terrain.          A fuel storage tank is formed integral with rear portions of the vehicle's hull and comprises a plurality of interconnected fuel cells defined by double wall construction of the hull body.  A fresh air inlet and deflector arrangement in the upper horizontal surface of the hull delivers fresh air forwardly to an engine compartment for cooling the engine, and warm air generated by the engine is re-versed in flow direction and exhausted via a conduit through an outlet opening immediately adjacent the fresh air inlet.

Abstract: GAS METAL ARC WELDING SYSTEM                   ABSTRACT OF THE DISCLOSURE          Power delivered to the welding arc from a constant current rapid response power supply is controllable to maximize arc stability particularly in out-of-position welding operations.  A first control modulates the output current from the power supply between a high value close to the maximum output value and a minimum value just sufficient to maintain the welding arc. This modulation is effected at a given frequency appropriately adjusted in accordance with the electrode material and diameter to maintain optimum spray metal transfer in the welding arc.  A further control is effected by pulse width modulating the output from the power supply in accord with a set-in current programmed signal which is compared with a current feedback signal or, alternatively, a set in voltage programmed signal which is compared with a voltage feedback signal.  This latter con-trol provides for operation of the power supply in a constant current control mode or alternatively, a constant voltage control mode.  Still further control of the power in the welding are is effected by pulsing the current be-tween base and peak levels at a relatively low frequency which enables control of the weld puddle in out-of-weld positions.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus for making wooden pallets includes a conveyor for moving a plurality of parallel stringers under a nailing machine where deckboards are nailed transversely across the stringers to form one side of the pallet.  During operation of the preferred embodiment, the gripping carriage of the stringer conveyor normally propels in front of it one set of stringers, on which three bottom deckboards have already been nailed to form a half-pallet, and pulls behind it a set of stringers that have had no deckboards at all nailed thereto.  As the stringer of the half-pallet move under the nailing machine, five deckboards are nailed to its upper surface to complete the pallet and, when the trailing stringers move under the nailing machine, a set of three deckboards are nailed thereto to form a half-pallet.  At a point downstream from the nailing machine, the full pallet is discharged and the gripper carriage starts to move rearwardly.  During this rearward movement, the half-pallet is inverted and positioned on what is now the trailing side of the rearwardly moving gripper carriage.  At a position on the upstream side of the nailing machine, the gripper carriage grasps a new set of stringers and starts forwardly again toward the nailing machine to have five top deckboards applied to the upper surface of the half-pallet to complete it, and have three deckboards nailed to the new set of trailing stringers to form a new half-pallet.

Abstract: ABSTRACT            A light modulator for generating a beam of phase modulated light including a source of polarized light, at least one and preferably two liquid crystal cells having a thin layer of nematic liquid crystals of positive dielectric anisotropy through which the polarized light is directed to produce a beam of light having a phase shift corresponding to a modulating electrical signal which is applied to each of the liquid crystal cells.  The liquid crystal cells in addition have a continuing electrical bias applied across the layers in order to achieve the rapid response times necessary to achieve modulation of the polarized light. Demodulation of the polarized light occurs by splitting the modulated light beam into its quadrature components and developing an electrical signal corresponding to the phase difference between the two quadrature components.  A communication system involving its modulators and demodulators delivers communication through light as a transmission medium.

Abstract: Adiabatic Positive Displacement Machinery Abstract Adiabatic positive displacement gas cycle machin-ery is designed with explicit control of the heat flow between the gas and the walls.  The control is achieved by maintaining near-laminar flow and a small wall area to volume ratio.  The most stable near-laminar flow in a cylinder is an axial vortex because of symmetry, and hence the induction port design should establish an axial vortex and a low velocity. Induction and exhaust port designs to achieve this flow are applied to a vane pump, an adiabatic air compressor, a diesel engine, and four stroke Otto cycle engines.  The gain in thermal efficiency for these designs can be significant, up to a factor of 2, since the largest inefficiency in nearly all posi-tive displacement machinery is imperfect control of heat flow.

Abstract: Abstract of the Disclosure An improved liquid filling valve for filling containers with carbonated liquid such as soft drinks is disclosed which features cocentric valves for introduction of counterpressure gas and product into the container. The container is moved into sealing engagement with the valve which movement is continued to open the valve for admission of counterpressure gas. After counterpressurization is completed the valve for admission of product opens automatically allowing product to fill the container.         After filling is completed, motion of the container away from the valve automatically closes it. In the bottle filling embodiment, motion of the bottle away from the valve additionally uncovers a snift port. The counterpressure filling and snifting of containers with carbonated liquids is thus accomplished without use of external valve operating cams or the like.
