Title: Waste disposal system and method
Inventor: DALLEN JOHN A
Filed: 1980-08-13
Granted: 1981-07-07
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is a portable waste disposal system that is designed primarily for use in marine craft, mobile homes, campers or the like.  The system comprises a macerator unit for converting excrement to a liquified effluent, and an incinerator unit for incinerating the effluent.  The macerator unit comprises a holding tank which receives the waste material from a toilet.  When the level of the excrement within the holding tank reaches a predetermined level, and maintains that level for a predetermined period of time, the system is activated and the excrement from the holding tank is macerated by a macerator and provided to a feed compartment.          A circulation pump then pumps the macerated effluent from the feed compartment through a circulation line to the incinceration unit.       The incineration unit comprises a combustion chamber and an additional feed pump which draws effluent from the circulation line and feeds the effluent into the combustion chamber.  A crucible is disposed within the combustion chamber for receiving the effluent fed therein. A burner is provided which introduces a high temperature flame into the combustion chamber to incinerate the effluent in the crucible.  The crucible is elevated from the floor and spaced from the walls of the combustion chamber so that the frame from the burner fills the entire combustion chamber and heats the crucible on all sides.  The effluent within the crucible is incinerated until all of the liquid is vaporized and the remaining solid waste material is reduced to a fine ash.

Abstract: ABSTRACT             MANUFACTURE OF COPPER BODIES         Copper bodies are made by the following sequence of steps:          (i)  The ore is crushed and if necessary concentrated by a flotation process;   (ii)  The prepared ore is oxidised by a hydrometallurgical technique to generate a solution containing copper cations and substantially free of sulphide anions;        (iii)  The copper cations are reduced without extracting them into a different solution (though they may if desired be concentrated or even crystallised out as a salt) to form a deposit of copper particles;         (iv)  The particles are substantially freed from deleterious surface impurities;  and (v)  The heat-treated copper particles are fed as such to a friction-actuated extrusion machine and extruded by that machine to form a coherent product.

Abstract: ABSTRACT OF THE DISCLOSURE     A gang mower typically having five or seven gangs which are raised and lowered by a single piston and cylinder.  Lifting arms are fixed to an actuating shaft at each side of the machine and the piston and cylinder are connected between opposed lifting arms to rotate them in opposite directions.  An equalizer link connected by cranks to the actuating shafts ensures that the shafts always rotate to equal extents in opposite directions.          Chains are connected from the lifting arms to the mowers, the chains and lifting arms being dimensioned so that lifting occurs sequentially, with some of the mowers being lifted before others.  The sequential lifting spreads the load more evenly throughout the lifting sequence, thereby permitting a single piston and cylinder to lift all of the mowers.

Abstract: ABSTRACT               HIGH DENSITY V-MOS MEMORY ARRAY     A method for providing high density dynamic memory cells which provides self-alignment of both V-MOSFET device elements and their interconnections through the use of a device-defining masking layer having a plurality of parallel thick and thin regions.  Holes are etched in portions of the thin region with the use of an etch mask defining a plurality of parallel regions aligned perpendicular to the regions in the masking layer.  V-MOSFET devices having self-aligned gate electrodes are formed in the holes and device interconnecting lines are formed under the remaining portions of the thin regions.  A com-bination of anisotropic etching and directionally dependent etching, such as reaction ion etching, may be used to extend the depth of V-grooves.  A method of eliminating the overhang of a masking layer after anisotropic etching includes the oxidation of the V-groove followed by etching to remove both the grown oxide and the overhang is also disclosed.

Abstract: ABSTRACT   A dimensionally-stable, non-collapsible highly porous foam based upon an insoluble protein-based polymeric material, is produced by forming a liquid dispersion of an insoluble protein-based polymeric material which does not flow under elevated tempera-tures, quickly freezing the dispersion to form frozen liquid particles, subliming the frozen liquid particles to produce a highly porous foam, and subjecting the highly porous foam to elevated temperature and vacuum conditions sufficient to stabilize the highly porous foam so that its porosity is preserved when it is contacted with a liquid solution of a chemical cross-linking agent.  The stabilized highly porous foam is then subjected to a liquid solution of a chemical crosslinking agent so as to produce a dimensionally-stable, non-collapsible highly porous foam material.

Abstract: (Case No. 7037) ABSTRACT OF THE DISCLOSURE    A selected unique digital comma-free code word is trans-mitted through track section rails from one end and, when received at the other end, is applied serially to a shift register which supplies a parallel readout of shifting pattern to one input of a fail-safe comparator.  The second comparator input is selected from the different possible digital code patterns of the track code word stored in a memory device.          When inputs are equivalent, the comparator passes an input test signal to its output.  Absence of comparator output causes the selected stored code word to be stepped through the stored patterns, in reverse order to track code shift, until equivalence is again obtained.  The periodic output signals, of approximately 50% duty cycle, are processed through a series filter-rectifier network, tuned to test and periodic output signal frequencies, to energize a track relay to register an unoccupied track section indication.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a method of monitoring the extent of throttling a sliding gate teeming valve where a hydraulic ram is employed by measuring the fluid flow in and out of the hydraulic cylinder which drives a valve, either for throttling, or positioning.  Shown is a hydraulic motor in series with the driving fluid with a rotary counter. The rotation of the motor is read out remotely and preferably digitally, with intermediate means translating the volume of fluid flow into a calculation of travel of the hydraulic ram which, in turn can be translated into the movement of the sliding gate valve.  Means for zero setting upon actuation are provided within the method.  The apparatus shows the combination of an hydraulic-type motor in the hydraulic line which drives the actuating cylinders of a sliding gate valve.  The rotation of the motor is then counted and calculated to read out in digital form, preferably electrically actuated and remote from the motor.  A logic circuit is provided to be actuated by the read-out to compute the hydraulic fluid displacement and indicate the position of the valve. Means for gearing the motor and counter for each operation is further included in the combination.

Abstract: AN ALL DIGITAL PHASE-FREQUENCY LOCKED LOOP            ABSTRACT OF THE DISCLOSURE                An all digital phase-frequency locked loop consists of an up-down counter as a phase-frequency comparator and low pass filter, a frequency multiplier as a controlled oscillator and a dividing counter as a jitter averaging filter.  A reference signal is applied to the up-count input of the up-down counter and the feedback signal is applied to the down-count input of the up-down counter.  The up-down counter's output controls the frequency rate multiplier to generate a variable frequency output.  This variable frequency is further filtered by a counter to average the jitter and increase the signal to noise ratio before it is applied to the down-count input of the counter.  The loop has a wide pull-in range, a fast acquisition time and is highly suitable for integration because of its all digital nature.
