Abstract: Devices, systems, and methods for drying a bulk waste product, such as animal waste, having a moisture content of 95% or more water can include a trough configured to receive the bulk waste product and to dispense it in a form suitable for convective drying, one or more conveyors having an air-permeable conveyor belt, each conveyor receiving the waste product from the trough and transporting the waste product along a transport path; and one or more air moving devices (AMDs) that pass air through the air-permeable conveyor belt and across the waste product as it is transported along the transport path to transform the bulk waste product into a dried waste product having a moisture content of about 5% to about 20%, inclusive.

Abstract: A method of fabrication of arsenic glass, comprising forming pellets of an arsenic-containing glass-forming mixture comprising arsenic in a range between about 30 and about 50% w/w and glass forming elements, and melting the pellets by direct heating to a temperature in a range between about 950 and about 1250° C.

Abstract: Apparatuses and processes for recycling printed wire boards, wherein electronic components, precious metals and base metals may be collected for reuse and recycling. The apparatuses generally include a mechanical solder removal module and/or a thermal module, a chemical solder removal module, and a precious metal leaching module, wherein the modules are attached for continuous passage of the e-waste from module to module.

Abstract: Burner holder for a burner of a melting vat, comprising a holding section for fastening the burner and a mounting section for fastening the holder to a melting vat or a vat element which is assigned to the melting vat, wherein the holding section (13) is connected via at least one parallel crank mechanism (8) to the mounting section (14) and can be moved via said at least one parallel crank mechanism (8) relative to the mounting section (14).

Abstract: A roller sealing device arranged at an access port of a continuous furnace for adapting a continuous processed planar processed material. The rolling device includes a pair of first roller carriers arranged correspondingly opposite to each other, each having a first roller assembly. Each first roller carrier includes a first sealing roller and two first auxiliary rollers; the first sealing roller and two first auxiliary rollers are pivoted to a respective one of the first roller carriers; the two first auxiliary rollers are located between the first sealing roller and the corresponding first roller carrier. The first auxiliary rollers rollingly abut against the first sealing roller and the corresponding first roller carrier. Therefore, the roller sealing device is sealed well so as to prevent the gas from leakage. The present invention further provides a gas-sealing method.

Abstract: The present invention generally provides a system for warming an outdoor surface. The system includes a heat exchange unit to provide heated air for use across the surface to melt snow or ice or to warm, evaporate or distribute water. The heat exchange unit is used to recapture the heated air. The present invention also generally provides a method of warming an outdoor surface. The method comprises the steps of providing heated air across the surface to melt snow or ice or to warm, evaporate or distribute water, recapturing the heated air, and redistributing the heated air across the surface.

Abstract: According to one embodiment, a heating apparatus includes, a heating chamber, a fan provided in the heating chamber, the fan blowing atmosphere upward, a heater provided in the heating chamber and above the fan, the heater heating the atmosphere blown by the fan, a plurality of first straightening vanes arranged in a substantially horizontal direction so as to be spaced apart from one another in the heating chamber and above the heater, a plurality of second straightening vanes arranged in a substantially horizontal direction so as to be spaced apart from one another in the heating chamber and above the first straightening vanes, each of the plurality of second straightening vanes overlapping both of its adjacent first straightening vanes, and a transfer unit which transfers a board, at least part of the transfer unit being provided in the heating chamber and located above the second straightening vanes.

Abstract: A threading and scale removing device is disclosed which includes a heating apparatus having an inlet and an outlet. A work-piece is fed through the inlet and exits through the outlet. A plurality of rollers are operatively associated with the heating apparatus. A belt is mounted on the plurality of rollers and is adapted to rotate through the heating apparatus. As the belt rotates, it functions to thread the work-piece through the heating apparatus. Once the work-piece has been threaded through the heating apparatus, the belt functions to catch and remove metal scales that flake from the work-piece during heating. A motor is operatively connected to the plurality of rollers for driving the rollers and allowing the belt to rotate through the heating apparatus.

Abstract: Rotation of a first drum member at a preselected speed intimately mixes finely divided agglomerative materials to form a loosely coherent, plastic sticky mass. The tumbling action generated by the rotating drum breaks up the loosely coherent, plastic mass into plastic particles or agglomerates which grow in size as they roll within the first drum member. The formed agglomerates are conveyed by rotation of the first drum member into a second drum member that includes an inlet portion surrounding the outlet portion of the first drum member. The second drum member has a longitudinal axis that is coplanarly aligned with the longitudinal axis of the first drum member and both drum members are independently rotated at preselected peripheral speeds with the angle of inclination of the first drum member being adjustable relative to the second drum member to control the movement of the agglomerates.
