    摘要： An apparatus for remotely calcining a slurry or solution feed stream of toxic or hazardous material, such as ammonium diurante slurry or uranyl nitrate solution, is disclosed. The calcining apparatus includes a vertical substantially cylindrical inner shell disposed in a vertical substantially cylindrical outer shell, in which inner shell is disposed a fluidized bed comprising the feed stream material to be calcined and spherical beads to aid in heat transfer. Extending through the outer and inner shells is a feed nozzle for delivering feed material or a cleaning chemical to the beads. Disposed in and extending across the lower portion of the inner shell and upstream of the fluidized bed is a support member for supporting the fluidized bed, the support member having uniform slots for directing uniform gas flow to the fluidized bed from a fluidizing gas orifice disposed upstream of the support member. Disposed in the lower portion of the inner shell are a plurality of internal electric resistance heaters for heating the fluidized bed. Disposed circumferentially about the outside length of the inner shell are a plurality of external heaters for heating the inner shell thereby heating the fluidized bed. Further, connected to the internal and external heaters is a means for maintaining the fluidized bed temperature to within plus or minus approximately 25.degree. C. of a predetermined bed temperature. Disposed about the external heaters is the outer shell for providing radiative heat reflection back to the inner shell.

    摘要： The invention relates to pin and socket joints for use in the steering and suspension systems of automobiles. The head of the pin is housed in a socket having an aperture through which the pin extends, the aperture being sealed by an annular boot having peripheral portions sealing against the pin and socket respectively.One of the peripheral portions is engaged in a groove in the pin or socket and the said one peripheral portion has interior passageways leading from the interior of the boot to the base of the groove and exterior passageways leading from the base of the groove to the exterior of the boot.These passageways facilitate the rapid escape of grease from the boot during excessive power filling of grease into the joint so that the boot is not disengaged from the groove.
