  • Patent number: 8123868
    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.

  • Patent number: 4917558
    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.

  • Patent number: 4466809
    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.

  • Patent number: 4448402
    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 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).

  • Patent number: 4342269
    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.

  • Patent number: 4261795
    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.
