Полезная модель относится к печам непрерывного действия для термической обработки мелкодисперсных материалов или суспензий, вязких жидкостей при контролируемой газовой атмосфере и температуре нагрева в режиме непрерывной работы и постоянном перемешивании материала. Реализация непрерывного поступательного движения и перемешивания рабочего материала осуществляется с помощью вращающихся компонентов в печи. Загрузочный и разгрузочный механизмы обеспечивают постоянное поддержание внутренней атмосферы и толщины слоя прокаливаемого материала. Оптимизация геометрии реторты совместно с индукционным методом нагрева позволяет значительно сократить массогабаритные показатели, обеспечить непрерывность процесса с сохранением заданной производительности, обеспечить высокую автоматизацию процесса, улучшить и расширить условия производства, эксплуатации и обслуживания. Также раскрыты модификации, когда отсутствует необходимость поддержания внутренней атмосферы и когда необходим наклон осей вращения реторты по отношению к горизонту.

A self-contained assay facility housed in a fixed-wing or rotary wing aircraft that is completely equipped to melt and assay precious metals, particularly gold and silver. An induction furnace melts the metal that is then poured into an ingot. The ingot is weighed and analyzed using an XRF alloy analyzer and the percentage of gold and/or other metals recorded. The value of the gold at current market prices is calculated and the assay and the value of the ingot is printed and given to the seller. The seller may opt to receive the ingot and pay the assayer an assay fee. Alternately, the seller may ask to be paid in cash, in bullion, by wire transfer, or by an open hedge. A transfer or hedge is initiated and confirmed from the assay facility. The ingots are securely stored in a safe within the assay facility.

Acicular mullite bodies are made in two-step firing process in which a green body is converted first to a fluorotopaz and then to acicular mullite. The bodies are contained within an enclosed region of the furnace. A flow of process gas is provided through the enclosed region during the fluorotopaz-forming step. The process gas is introduced into the enclosed region through multiple openings on at least one side of the enclosed region, and withdrawn through multiple openings on another side of the enclosed region. During the acicular mullite-forming step, a flow of purge gas is maintained in the exterior portion of the furnace. This purge gas may be removed by flowing it into the enclosed region of the furnace and out of the furnace from the enclosed region without re-entering the exterior portion for the furnace.

The present invention generally describes apparatuses and methods used to perform an annealing process on desired regions of a substrate. In one embodiment, pulses of electromagnetic energy are delivered to a substrate using a flash lamp or laser apparatus. The pulses may be from about 1 nsec to about 10 msec long, and each pulse has less energy than that required to melt the substrate material. The interval between pulses is generally long enough to allow the energy imparted by each pulse to dissipate completely. Thus, each pulse completes a micro-anneal cycle. The pulses may be delivered to the entire substrate at once, or to portions of the substrate at a time. Further embodiments provide an apparatus for powering a radiation assembly, and apparatuses for detecting the effect of pulses on a substrate. 1.
