Abstract: Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.

Abstract: A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

Abstract: A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.

Abstract: A substrate for a tamper sensor includes a plurality of walls and a tab. The walls define a protective volume with an open side. The walls have a plurality of open edges adjacent the open side and a plurality of interior edges different from the open edges. The tab extends from one of the interior edges of one of the walls and is disposed within the protective volume.

Abstract: This invention provides a system and method for sterilizing an ISO 594 female Luer fitting and an attached catheter using UV light. An optical plug can be inserted into a female Luer fitting, and UV-C light or a combination of UV-C and UV-A light can be radiated through the optical plug and into the female Luer fitting and attached catheter, thereby sterilizing the fitting and catheter. A sterilizer device can be used to hold the female Luer fitting and catheter, with an optical plug inserted into the female Luer fitting. The sterilizer device can include a UV light source that radiates UV light through the optical plug and into the female Luer fitting and attached catheter. A protective cover can be placed over the optical plug before inserting the optical plug into the female Luer fitting. The protective cover can be disposable.

Abstract: The present technology describes various embodiments of systems and methods for maintaining a flat push hot car. In some embodiments, the flat push hot car includes an at least partially enclosed hot box having an interior portion, an exterior portion, a base, and a plurality of sidewalls extending upward from the base. The hot box can be coupled to or integrated with a fluid distribution system. The fluid distribution system can include a spray manifold having one or more inlets configured to release a fluid directed toward the sidewalls of the interior portion so as to provide regional cooling to the hot box.

Abstract: A tamper sensor assembly that includes a substrate with a protective bulk section including tamper circuitry and a hardware section configured to receive hardware circuitry and extending from the protective bulk section; the hardware circuitry electrically connected to the tamper circuitry to alter operation of the hardware circuitry responsive to modification of the tamper circuitry. The substrate additionally includes an attachment section extending from the hardware section. The tamper sensor assembly also includes a first fold in the substrate to position a first portion of the hardware section to extend along the protective bulk section, and a second fold in the substrate to position a second portion of the hardware section to extend along the first portion of the hardware section.
