Abstract: A temperature measurement system for a gasifier may employ a first stage gasifier with a refractory wall that defines a first stage gasifier volume. A protruding refractory brick may protrude from the first stage refractory wall and into a gaseous flow path of the first stage gasifier volume. The temperature sensor may reside completely through the refractory wall, which may be a plurality of brick layers, except for a tip end of a temperature sensor that may reside in a blind or non-through hole within the protruding refractory brick. The protruding refractory brick protrudes beyond a normal wall surface of the plurality of brick layers that defines the first stage gasifier volume. The protruding refractory brick may have a face that forms an angle that is not 90 degrees, such as 45 degrees, relative to the gaseous flow path of the fluid stream through the first stage gasifier volume.

Abstract: A magnetic mounting assembly includes a plate carried within the housing. The plate has a central opening and multiple apertures offset from the central opening with a permanent magnet carried within each of the apertures. A cover is compression fit with the housing for securing each magnet between inside surfaces of the cover and the housing , and within the aperture. A central opening is formed with the housing, the cover, and the plate for receiving a fastener when fastening the assembly to an object.

Abstract: A chair of knock-down construction includes a back, a seat in locked engagement with the back, and first and second legs in locked engagement with the back and seat. Each of the legs includes a corner portion having wall structure, defining slots, for holding the back and seat in locked engagement. The back includes two lower side corner portions, each defining a pair of projections for holding a leg and the seat in locked engagement. In addition, the seat includes two rear corner positions having wall structure, defining two cut-out holes; and the wall structure defining each hole concurrently engages the back and a leg. Each cut-out hole includes a slot portion and a pair of projection-receiving portions which intersect the slot portion. The chair, which is assembled, without fasteners, from interlocking components, further includes a cross-support in locked engagement with each of the legs, which supports the seat.
