Patent EP-0246191-A2 (EP)
Inventor: LEE BERNARD S
IPC: F23G5/30
Filed: 1987-05-08
Abstract: A process for thermal treatment of solid particles in a fluidized bed wherein the solid particles by thermal treatment form a lighter weight fraction and a heavier weight fraction, relative to the total contents of the bed. The process is characterized by use of a selective heavier particle discharge conduit in the sloping bed support and maintenance of a discrete fluid fueled flame in close proximity to and above the opening to the heavier particle discharge conduit. This forms a higher temperature zone in and surrounding the flame, at least about 100°F higher than the remainder bed temperature. Circulation of solid particles through the flame and its surrounding highertemperature region is promoted both by directing of fluidization gas jets in the fluidized bed support and by the jetting action of the upwardly flowing heavier particle discharge gas.

Abstract: A feeler head for coordinate measuring machines has a torsionally stiff, zero-backlash and frictionless spring system which defines a spatial coordinate system and carries a feeler that can be displaced in all three spatial directions. Provided for each of the three coordinate directions is a position measuring system, which preferably operates incrementally and is connected in each case to a zero indicator for detecting the zero position of the system. In the event of contact between the object to be measured and the feeler head, a trigger pulse is initiated by a sensor. A downstream electronic system processes the different signals supplied by the feeler head in an optional fashion such that the feeler head can be operated to switch or to measure. <IMAGE>
