Title: Process for purification of exhaust gases, in particular from waste incinerators
Inventor: RITTER JURGEN
IPC: B01D53/60
Filed: 1991-04-13
Abstract: Abstract Process for purification of exhaust gas (1) from waste incinerators, especially refuse incinerators (2), wherein the exhaust gas (1) is dedusted, conditioned and passed through an adsorber (6) charged with activated coke (7) for separating off pollutants. The unpurified exhaust gas (1) is passed through the adsorber (6). The adsorption is controlled in such a way that the gas (8) leaving the adsorber (6) is almost free of SO2. HCl and HF for producing re-usable products, especially hydro-chloric acid and/or NaCl, is taken off from the unpuri-fied gas  (8)  leaving the  adsorber  (6).  By means  of multiple adsorption (6, 14, 25, 36) and regeneration (20, 29), on the one hand the exhaust gas (1) is purified and, on the other hand, the pollutants are separated from the exhaust gas (1) and further processed to give saleable products. (Figure 1).

Title: Multi-stage process for deasphalting resid, removing catalyst fines from decanted oil and apparatus therefor
Inventor: BEATON WILLIAM I
IPC: C10G67/04
Filed: 1992-03-23
Abstract: The invention reduces cracking catalyst fines in decanted oil by mixing the decanted oil (DCO) containing cracking catalyst fines with a resid oil and then treating the DCO-resin mixture with a non-aromatic hydrocarbon solvent in an extraction unit. The presence of catalyst fines facilitates deasphalting of hydrotreated resid. The invention represents an improvement over the prior art because the prior art, among other things, does not teach or suggest feeding solvent extracted deasphalted oil and resins to a hydrotreating reactor or mixing a decanted oil containing cracking catalyst fines, as does the invention.

Title: Flexible cord winding and packaging configuration and method of making such package
Inventor: LILLEY THOMAS F JR
IPC: F42B39/30
Filed: 1992-04-22
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention combines the advantages of a prior art figure of 8 winding pattern with the traditional circular or oval pattern for packaging flexible cord to form what can be called a "figure of 80 pattern" which includes a generally S-shaped partial cord layer with the end of the S joining with a J-shaped portion arranged so that the straight portion of the J forms a continuation of the S and the curved portion of the J overlies the beginning of the S-shaped portion.  This  basic combination of S and J shapes designates only partial layers, the pattern can be repeated, that basic pattern can be connected to a plurality of oval turn layers or even a plurality of figure 8 turn layers as the user may elect.  It is also possible to continue to merely alternate the basic layer form to provide a package having a high packaging density while permitting easy accommodation of fittings which are secured to the end of the cord.

Title: Polymer coated powder heating and feeding system for a compacting press
Inventor: SMYTH DALE C JR
IPC: B30B11/00
Filed: 1992-05-26
Abstract: A system for heating and feeding polymer coated powder to a heated die cavity of a compacting press.      The system comprises at least one heated vertical pipe for heating the polymer coated powder and for delivering the polymer coated powder by gravity from source thereof to the entry end of at least one horizontally oriented auger conveyor. The at least one auger conveyor is heated and imparts heat to the individual powder particles through a mixing action.     The at least one auger conveyor delivers the polymer coated powder to the heated hopper of a shuttle assembly. The shuttle assembly is shiftable between a retracted position wherein the polymer coated powder is discharged from the shuttle hopper to a heated powder ring, to an extended position wherein the polymer coated powder is discharged from the powder ring to the heated die cavity of the compacting press. The system heats the individual particles of the polymer coated powder to a temperature just below the coagulation point thereof. The temperature of the polymer coated powder is rapidly increased to the "set" point by the combination of the heated die cavity and the energy imparted during the actual compacting stroke.

Patent CA-2077659-A1 (CA)
Title: Segregated format processing of combined text and pictorial image data
Inventor: O'BRIEN DONALD E
IPC: H04N1/387
Filed: 1991-12-24
Abstract: An imagery data and text formatting mechanism for an image processing system in which a color photographic image on a color slide is digitally encoded and stored in bit map format on a compact disc. Photographic image-representative digital data stored on the disc is readable to cause the generation of the image by an output device. When text is to be inserted into the image, an ASCII  file, separate from the bit map formatted photographic image file, is incorporated into that part of the data base where control information is stored. The ASCII file contains a font descriptor and an identifier of where within the bit map the text is to be inserted. When imagery data stored on the disc is to be read out, for example, supplied to a high resolution thermal printer, a text-representative bit map file is generated in accordance with the contents of the ASCII file and combined with the bit map data file for the photographic scene image. Because the text is separate from the scene data, applying an image modifying operator to the scene will not corrupt the text or cause artifacts to be introduced into the scene as would occur with bit map text.

Title: Downfired boiler having vertical heat transfer tubes
Inventor: MOSCONE ROBERT T
IPC: F24H1/28
Filed: 1993-02-16
Abstract: A water-heating boiler of the tube-shell type is designed, so that the heat transfer tubes are vertically oriented. During movement of the hot combustion gases, from the large combustion tube into the smaller heat transfer tubes, the directional change in the gas, is augmented, by a changing effect of gravitational forces on the combustion gas stream. Inertia effects, in combination with velocity changes, produce a relatively high turbulence in the flowing combustion gas, with a corresponding increase in the scrubbing effect on the heat transfer tube walls.
