Title: Method and apparatus for the intermittent,  regenerating cleaning of a filter bed
Inventor: BERZ WOLFGANG
IPC: B01D46/30
Filed: 1979-12-21
Granted: 1982-07-13
Abstract: ABSTRACT A shell and two perforated cylindrical walls are radially spaced about a common vertical axis so as to define three coaxial spaces.  A gas to be purified of suspended particles is admitted to the annular first space between the shell and a filter bed of granular material in the second space between the two perforated walls, and a purified gas is withdrawn from the third space.  To clean the filter bed, granular material is conveyed from the lowermost portion of the second space through a conduit to a separating device above the topmost portion of the filter bed by a stream of conveying gas, and the gas entrains most of the particles from the granular material while the latter returns to the second space by gravity.  The particle-laden conveying gas is introduced tangen-tially into the top portion of the annular first space where it is mixed with a scavenging gas passed through the filter bed from the third to the first space. The gas mixture with the particles suspended therein descends in a spiral path through the first space, the particles are precipitated as in a cyclone, and gas and particles are withdrawn separately from the bottom of the first space.

Abstract: ABSTRACT OF THE DISCLOSURE:         A body serving for accommodating material to be processed is movable in gimbal suspensions around two mutually spaced axes extending in different directions. The body carries out a rotary and tumbling movement by oppositely rotating two parallel shafts of which each is connected with one of the gimbal suspensions.  For balancing torque fluctuations, a pair of discs is arranged on each shaft of which the driving-side disc is rotatable relative to the shaft and is connected with a drive wheel while the driven-side disc is fixedly con-nected with a shaft.  In an annular channel between the discs energy stores in the form of coil compression springs and balls are alternatingly and successively arranged.  These elements bear against respective abutments of both discs projecting into the channel. When the discs rotate relative to each other, the springs store forces arising at torque excesses which are then subsequently released.

Abstract: ABSTRACT           The nitrogen content of low carbon steel made by the basic oxygen process is minimized by:          (a) introducing nitrogen-free fluid into the vessel before the nitrogen content of the melt has reached its minimum level, (b) adjusting the flow rate of the nitrogen-free fluid to maintain total off-gas flow rate at least equal to that which would have been produced without the nitrogen-free fluid at the time in the refining process when the nitrogen content of the melt reached its minimum level, and (c) the injection of nitrogen-free fluid throughout the remainder of the oxygen blow.          A preferred additional or alternatively separate step involves minimizing the nitrogen content of BOP steel by purging the vessel headspace with a nitrogen-free fluid prior to reblows.

Abstract: Abstract of the Disclosure Apparatus is described for continuously pro-ducing finger jointed lumber from individual elongated boards.  Each board includes opposed end faces with elon-gated parallel fingers that will mate with complementary fingers of a following board to form end-jointed lumber.          A reciprocating ram engages one end of successive indi-vidual boards, pushing the board longitudinally along a path to a confining box.  The ram retracts to engage a successive board along its end face to push it longitudi-nally into engagement with the board held by the confin-ing box.  The fingers of the engaging board ends mate within the confining box and are pressed together to com-plete a joint.  The ram includes a ram face that is com-plementary to the finger configuration of the board ends to mate intimately with the board end.  The ram face may be heated to apply heat to the successive board ends for glue curing purposes.  The successively engaged boards are pressed firmly together to complete the joint by op-eration of the ram or by auxiliary moving clamp assem-blies along the framework of the apparatus.
