Abstract: A system for processing material for a gasifier. The system comprises an auger feeder adapted to receive material to be gasified. The auger feeder is adapted to feed the material. A tube is connected to the auger feeder such that the tube is adapted to receive the material from the auger feeder. The tube is also connected to a gasifier, which is adapted to receive the material from the tube.

Abstract: A method and apparatus for cleaning, drying, coating, baking etching and deposition of surfaces on glass substrate as it transitions thru and between small gaps between hydro-static porous media bearings. Due to the non-contact nature of the device extremely high pressures can be induced upon the work piece through various fluids without damage to the substrate, allowing the system to utilize the viscous nature of fluids to accomplish the desired cleaning, drying, coating, etching or baking. The process also allows for simultaneous and immediately sequential ordering of processes.

The apparatus includes: a screw feeding housing with a drive motor, and a screw; and a biomass inlet, wherein the biomass is dropped in the biomass inlet and the screw feeds the biomass into the pressurized vessel.

Abstract: A fluid cooled conveying screw adapted for rotary hearth furnaces. A plurality of solid alternating single and double flights are affixed to an outer barrel. The single flights are at least partially cladded to withstand the rigors of the furnace. The double flights extend partially down the barrel.

Abstract: A device and method for holding and delivering a load of particulate material such as wood blocks, wood chips--dry or moist--, and briquettes. A main bin has an open upper end, closed side walls, and a closed bottom wall. A pair of drive shafts are journaled across and in the side walls of the main bin, with a motor therefor. A flexible belt has one end secured to a first such drive shaft on one side of the bin and another end secured to a second such drive shaft on the opposite side of the bin. A continuous chain driven by the motor drives said drive shafts, and there is an idler associated with the chain and one of the drive shafts for reversing the direction of rotation of that drive shaft, so that rotation of the two drive shafts slackens the belt enabling loading. The belt, when tightened and raised, drops the load into said main bin.

Abstract: A stoker assembly for a solid particulate burning stove that includes a fuel directing flange for directing the fuel to an upper combustion plate and ventilation tubes to prevent the ignition and combustion of fuel stored in remote bins. The fuel directing flange serves to prevent the solid particulate fuel from falling back into the auger conveyor and being ground into smaller particulate matter.

Abstract: An apparatus for feeding a combustor with viscous bulk material, particularly coal slurry, comprises two silos which are associated with at least one conveyor system, for transporting the bulk material from the silos to a plurality of fuel-feeders in the combustor. Advantageously, two conveyor systems are linked with each other so that bulk material can be distributed uniformly either from both silos or from one of the silos to all the fuel-feeders of the combustor.

Abstract: A waste product feeder in which when waste products are charged through a hopper into a trough are transported by a screw and then discharged, they are successively scraped by a scraper in a predetermined quantity or volume.

Abstract: A jig for arraying and supporting a multiplicity of articles to be soldered wherein pairs of lower supporting wires are extended for supporting the lower side of respective articles between frame members adapted to be secured to a conveyor holder of a soldering line, pairs of upper supporting wires are arranged above the lower supporting wires in parallel with the latter along both side surfaces of respective articles, one end of each of the upper supporting wires being passed loosely through a hole formed on the frame member, and a gate member supporting the other ends of said upper supporting wires is provided movably up and down with respect to the frame member.

Abstract: A top drying nozzle device for a vehicle washing apparatus has a link mechanism for supporting a top nozzle. The link mechanism has a pantagraph mechanism and two parallel link mechanisms so that the top nozzle can be moved vertically in a forward position of two side nozzles.

Abstract: Method for supplying fuel material to a gasification reactor into which a mixture of finely powdered fuel material, in suspension in a liquid phase, is charged inside a pressurized combustion chamber into which the combustion-supporting gas is injected and constituting the reactor, by means of a screw conveyor producing a continuously fluid-tight plug by compression of the driven material. By intermeshing at least two overlapping screws with identical threads rotated in the same direction, a wringing of the mixture introduced through an input orifice is compressed by regulating the flow rate of the mixture supply and the rotary speed of the screws so that, for a given flow rate of material, the plug constituted in a braking zone is at a given pressure and contains a certain proportion of liquid phase. The additional amount of liquid phase is expelled into the braking zone and reascends upstream into a drive zone where it is removed through orifices formed in filtering parts of a sleeve.

Abstract: A device is described for directly making liquid pig-iron from coarse iron ore. Hot sponge-iron particles are directly conveyed by a worm conveyor (17) through a communicating passage (19) from a direct-reduction blast-furnace shaft (2) into a smelter-gasifier (1), and a stream (24) of gas flows, after cooling to below 950.degree. C., in counter-current to the sponge-iron particles, from the smelter-gasifier (1) to the blast-furnace shaft (2), this gas stream having a volumetric flow-rate not more than 30 percent of the total reduction-gas flow reaching the blast-furnace shaft (FIG. 1).

Abstract: A material treating apparatus, such as an incinerator, incorporating an auger having an internal air supply system and an internal heat transfer mechanism. The incinerator includes a cylindrical combustion chamber containing a rotatable auger, and waste material is fed to one end of the combustion chamber and is conveyed through the chamber by the auger, while ash and non-combustible residue are discharged from the opposite end of the chamber. The auger is composed of a tubular shaft which carries a hollow spiral flight. Air is introduced into the downstream end of the shaft and flows through the hollow flight and is discharged through outlet ports in the periphery of the flight into the combustion chamber. To cool the auger, water flows within internal passages in the hollow flight. The flight is formed with a forward wall facing downstream and a rear wall which is spaced from the forward wall to define a central air passage.

Abstract: In a calciner having a rotatable cylindrical retort, an improved material feed spiral has a final turn and a 3/4 turn ending immediately adjacent the retort and a next to final turn connected to the final turn and extending outwardly therefrom away from the cylindrical retort. The final turn and 3/4 turn are of a height substantially equal to a given percentage of the inner diameter of the retort and the next to final turn tapers from a height substantially equal to the given height of the final turn to a height less than the given height.

Abstract: This disclosure is directed to an economical system for the pyrolysis of municipal solid waste to recover valuable by-products while reducing the putrefaction and bulk of the residue requiring disposal. Prior to this treatment, the solid waste has been processed to remove most of the metallic components, and shredded, which steps are not part of the invention disclosed. The pyrolysis and by-product recovery technology is complicated by (a) the inherent variability of the chemical and physical characteristics of the shredded solid waste as received at the pyrolysis plant and (b) the relatively low heat value of said waste as thus received.
