Abstract: A system and apparatus is disclosed for delivering fuel to a furnace using an inert gas medium which has acquired moisture from the application of the furnace stack gas for drying the incoming fuel material during the reduction of the fuel to a desired size for combustion in the furnace. The use of an oxygen deficient inert gases medium as a propellant to deliver the fuel to the furnace is augmented by supplying air to the furnace to establish a staged combustion environment in the furnace to avoid the generation of high levels of the pollutant nitrous oxide which is understood to be generated by high flame temperatures and with high oxygen and nitrogen concentrations.

Abstract: An off-line web finishing system performs plural functions on a pre-printed and rewound web at a series of pieces of equipment arranged in a line. Tension in the web is set at a variable infeed at a constant value that is sufficient to facilitate handling of the web. A common web-transport system drives all draw rolls in the line in unison, at the same speed, and without slippage between the web and the rolls. In the preferred form, a second drive line rotates in unison the function cylinders of pieces of equipment that are registration sensitive. The second line is driven by a main line shaft of the web transport system via a variable transmission that is adjusted in response to at least one optical scanner that senses misregistrations between the printed pattern on the web and the function cylinders. The registration sensitive function cylinders operate on the web only intermittently.

Abstract: The apparatus herein comprises a kettle for calcining particulate material and a surrounding furnace having a porous wall to pass heat of combustion into the kettle at one side and to permit evacuation of the products of combustion from an opposite side, and a control system to cycle the combustion and the evacuation of products of combustion between the opposite sides so that the side being evacuated becomes a heat sink to return the heat so retained therein upon the combustion cycle whereby the furnace structure is kept to a desirable level of temperature while the material in the kettle is at a significant higher temperature.

Abstract: A rotary die cutter includes an anvil roll and at least one die roll. One or more sheet metal dies with raised cutting edges are carried on the die roll to cut patterns in a web of material passing between the die and the anvil roll. The die cutter has a pair of rigid side frames spanned by a very rigid spreader. While the anvil roll is end-mounted between the side frames, the die roll is mounted from the spreader. A drive shaft rotatable in the side frames and driven from a lineshaft by a gear system transits rotation to the die roll, while allowing the die roll freedom of movement for independent vertical, axial and circumferential adjustments. This mounting and drive of the die roll can accommodate a full width press web using die rolls having a small diameter, typically a single repeat roll, and one whose length is comparable to its circumference. A pair of mutually slidable wedges acting against a spring clamping force adjusts the vertical position of bearing blocks that rotatably mount the die roll.

Abstract: A material grinding mill of reversible character having hog-type hammers formed with chisel edges pivotally mounted on supporting discs, and further formed with landing areas positioned to contact the supporting discs so that the chisel edges are prevented from impacting upon or nicking the discs. The pivoting of the hammers allows them to rebound when encountering a body of hardened material so the hammer reverses direction, hence the landing area impacts on the discs and the discs are protected against being nicked by the chisel edges of the hammers.

Abstract: An apparatus arrangement in a system for circulating an inert fluid medium in a substantially closed and inert atmosphere during the grinding of wet gob to prevent spontaneous combustion and the initiation of fire from sparks created during grinding of moisture bearing waste material. The apparatus combines with a grinding mill a fluid circulating circuit with the grinding mill to separate ground particulate gob from the circulating fluid medium, and a second fluid circulating circuit in association with a boiler to burn the ground gob material for creating an oxygen deficient atmosphere in the fluid circulating circuit.

Abstract: A system for recovery of the heat value of waste material, that heretofore has been wasted through landfill disposal, but in which the collected bales of waste material are passed through a bale breaker to release the waste material into a free condition so it can moved in a free flowing stream into a conveyor-type storage unit for movement to a grinder which reduces the mix of waste material to a substantially uniform particle size prior to being air moved into a boiler for recovery of the heat value which on burning produces steam to drive a generator to produce electrical power for energizing the power consumers in the system, with any excess being fed to an external power grid.

Abstract: A method for disposing by incineration of oil contaminated waste material after removal of solids of various kinds by performing multiple steps in its handling wherein the composite material is first subjected to a first classification step for extracting a high percentage of contaminant free material. After subjecting the material to a second classification cyclone where the gases that are used to transport the ground matter can be separated while the solids are subjected to classification by the use of a vibratory screen where the paper, fluffy waste, and similar material can be separated from the smaller and harder particulate components. The separated components are subjected to individual impact grinding steps prior to being recombined in the combustor where incineration takes place.

Abstract: A method for disposing by incineration of waste material containing sludge and garbage of various kinds which when combined results in a composite waste material prepared by performing multiple steps in its handling wherein the composite material is first subjected to a grinding step for thorough intermixing of the sludge that may contain a high percentage of moisture with garbage that can contain very little moisture. After grinding, the composite waste material is processed in a cyclone where the gases that are used to transport the ground matter can be separated while the solids are subjected to classification by the use of a vibratory screen where the paper, fluffy waste, and similar materials can be separated from the smaller and harder particulate components. The separated components are subjected to individual impact grinding steps prior to being recombined in the combustor where incineration takes place.

Abstract: A reversible downdraft rotary hammer mill for processing waste material in which breaker plates and a grate assembly are cooperatively arranged so the terminal ends of the grate assembly are laid back to form with the adjacent terminal ends of the breaker plates, when a terminal end of one breaker plate is opened relative to the tip circle of the rotary hammers and the other breaker plate is closed up to be adjacent the hammer tip circle, a tapering wedge shaped space for the opened breaker plate and a crushing surface for the closed up breaker plate. The cooperation of the breaker plates and the grate assembly enables the processing of a high volume of lightweight and fluffy material while avoiding plugging of the mill inlet.
