A seal assembly comprising a ring having radial and axial seals thereon positionable between mating parts for sealing flow of fluid from high to low pressure regions between the mating parts.

Floating dual direction seal assembly

A labyrinth seal for sealing the gap between the rotating impeller assembly and the stationary housing of turbomachinery comprising a seal holder which serves simultaneously to comprise the stationary part of the seal and to contact process gas so as to maintain the stationary seal part temperature at about the temperature of the rotating part, thus reducing differential thermal change between the stationary and rotating members of the labyrinth seal.

Controlled clearance labyrinth seal

Apparatus for disposing of pelletized refuse by conversion into useful gaseous products and inert solid residue, comprising a vertical shaft and an enlarged hearth beneath the shaft, with a multiplicity of tuyeres for feeding oxygen-containing gas into the hearth.

Solid refuse disposal apparatus

Process for solid refuse disposal in which a vertical shaft furnace is maintained at 30-250 psia, part of the recycle-condensate is filtered to form liquid waste a portion of which is incinerated with a minor part of the product gas to form hot exhaust gas used to heat feed water in steam boiler zone, and energy from the resulting steam is recovered as part of the process energy requirement.

Solid refuse disposal process

A vertical shaft furnace for the pyrolysis of pelletized refuse, having a hearth in the base provided with a refuse bed support structure comprising a plurality of cooled, refractory support members, extending radially inward from the wall toward the axis of the hearth. The support structure is characterized by having a plurality of peripheral spaces extending through side structure and converging in the downward direction, each of the peripheral spaces being formed, at least in part, by the side wall surfaces of adjacent support members and the inside surface of the hearth.
