Title: Burner for premixing combustion of a liquid and/or gaseous fuel
Inventor: DOEBBELING KLAUS
IPC: F23R3/28
Filed: 1992-02-24
Abstract: ABSTRACT OF THE DISCLOSURE In a burner for premixing-type combustion of a liquid and/or gaseous fuel, which essentially comprises hollow conical part-bodies (1, 2) positioned one upon the other, the center lines of which extend mutually offset in the longitudinal direction, whereupon tangen-tial inlet openings (lb, 2b) are formed on both sides of the burner, a fuel (5a) is admixed to the combustion air (13) flowing into the interior (3) of the burner in that area. This admixture is accomplished via a number of nozzles  (9,  10), which act in the region of the inlet openings (1b, 2b). The fuel through these nozzles is  injected with  a  small  spray  cone  angle  in  the longitudinal   direction   of   the   slot.   The   fuel vaporization takes place essentially only in the inlet openings of the burner, with the result that only a fuel vapor enters the interior (3). A further central nozzle (4) supplied with a liquid and/or gaseous fuel provides  assistance  in  the  form  of  a  limit  fuel quantity.  The ignition of the mixture  (4a,  5a,  13) takes place at the outlet of the burner, stabilization of the flame front  (14)  being brought about in the region of the burner aperture by a return flow zone (15).

Title: Method and apparatus for sludge collection
Inventor: COUDRIET LAWRENCE A
IPC: B01D21/18
Filed: 1992-03-31
Abstract: An upper carriage floats on the surface of a settling pond or tank of liquid containing sedimentation settled out to form a bed of sludge in the bottom of the tank.  A scraper assembly is suspended from the upper carriage by flexible cables or chains to a preselected depth in the tank.   Scraper blades supported by the scraper assembly extend downwardly into contact with the sludge bed.   The carriage is propelled on a looped cable across the surface of the tank and applies a tractive force through the suspension cables to the scraper assembly.  As the submerged scraper assembly advances, the scraper blades apply a shear force to dislodge the sludge from the bed and direct the sludge to a pump carried on the submerged scraper assembly.  The dislodged sludge is pumped through a hose from the tank.  In response to an excessive shear load applied by the sludge bed resisting forward movement of the scraper blades tending to force the leading edge of the assembly to move downwardly, the length of the leading cables is shortened to raise the leading edge to a position to permit continued shearing action of the scraper blades.

Filed: 1992-06-03
Abstract: "METHOD FOR TREATING AQEOUS STREAMS CONTAINING UNDESIRED AMOUNTS OF CYANIDE"                            ABSTRACT A cyanide-containing aqueous stream is treated to reduce the cyanide concentration by oxidation of cyanide using oxygen as the oxidizing agent under mild reaction conditions in the presence of a metal chelate catalyst. Especiallyeffective chelates are metal phthalocyanines, particularly where the metal is vanadium or a member of the iron group metals. The oxidation can be effected homogeneously using water soluble metal chelates, or can be performed heterogeneously, especially in a continuous fashion using a packed bed reactor, by using suitable water-insoluble metal chelates, especially when supported on appropriate carriers.
