Title: Contact reactor for a quasi-isothermal catalytic reaction of so2 to so3 and method of operating the reactor
Inventor: TACKE MICHAEL
IPC: B01J8/02
Filed: 1993-05-21
Abstract: ABSTRACT    To effect a quasi-isothermal catalytic reaction of SO2 to SO3, a plurality of consecutive rows of oanks of cooling tuoes, are provided in the bed of shaped catalyst boddies in a contact reactor in such a manner that the banks of succeeding rows are staggered from the oanks of the preceding rows. The distance between the cooling tuoes in the oanks is so selected that a penetration of entire catalyst boddies into the oanks will virtually oe prevented. The oanks are so designed that the pressure drop of the gas in the oanks is approximately the same as the pressure drop in the layer of catalyst oetween the oanks. The distance oetween the oanks is larger than the width of the oanks.

Title: High throughput, low cost, non-impact printing
Inventor: DOANE I GERALD
IPC: B41J11/42
Filed: 1993-07-05
Abstract: A method and apparatus are capable of producing sealed mailers from sheets of paper at speeds in excess of 200 documents per minute (e.g. 400 documents per minute or more) in an inexpensive manner, including by variably non-impact duplex printing the faces of each sheet with up to thirty six lines of variable data with each line up to ten inches long. The sheets are fed one at a time from a stack and then immediately aligned. Immediately after alignment the first face of each sheet is ink jet printed with variable data, the sheets are inverted and then immediately the second face of each sheet is ink jet print with variable data. The printed sheets are immediately folded, and if they have adhesive (such as pressure activated adhesive) they are immediately sealed. They may then be sorted, stacked, and tied into bundles. Control of all of the operations is provided by a central computer control which ensures that the processing speed is consistent throughout. The method is particularly suited for producing simple mailer type business forms such as 1099 forms, statements, notices, and advertisements.

Patent CA-2112053-A1 (CA)
Inventor: KODAMA JUN
IPC: G03G9/08
Filed: 1993-12-21
Abstract: Surfaces of fine polystyrene (PS) and polymethyl methacrylate (PMMA) powders were modified by exposure to the downstream products of a nitrogen or oxygen microwave plasma. The effects of nitrogen and indium incorporation in the powder surface were studied with emphasis on variations in the triboelectric properties of the powder. X-ray photoelectron spectroscopy (XPS) was utilized to determine the changes in surface elemental composition. After nitrogen plasma treatment, the C 1s peak profiles suggested the formation of amines in the case of PS, and the formation of imines and amides in the case of PMMA. Oxygen plasma treatment suggested the formation of hydroxyl and carbonyl groups on the surfaces of both PS and PMMA. After treatment with a nitrogen or oxygen plasma, the charge-to-mass ratio (Q/M) of PS and PMMA powders in contact with carrier particles was measured using the cage blowoff method. The surface charge density (Q/A) was calculated from Q/M. The Q/A of nitrogen plasma-treated PS powder was seen to shift towards positive charge with small increases in the nitrogen concentration. The Q/A of oxygen plasma treated PS powder initially shifted toward negative charge, but changed towards positive charge with higher oxygen concentrations. Plasma-treated PMMA powder showed a different behaviour and the variation of Q/A on PMMA was much less than that of PS. Results suggest that triboelectrification of the polymer powder may be related to changes in the electrical surface states, and that nitrogen may act as a group V dopant within the PS surface.

Title: Process for immobilising organic and inorganic pollutants in contaminated soil on reconstruction sights
Inventor: KRUSE KAI
IPC: G01N33/24
Filed: 1993-09-03
Abstract: ABSTRACT   The proposal is for a process for immobilising organic and inorganic pollutants in contaminated soil materials in which each partial reconstruction area of a reconstruction site is purified in the best possible way of an on-site application representing no danger for the surrounding medium groundwater. With a pre-measured clay mineral content of 60 wt % or more, both organic and inorganic pollutants are reduced and immobilised by means of multiple flushing (step 12) with an alkyl ammonium compound. With a pre-measured clay mineral content of 60 wt % or less the controlled insertion (step 10) of a bentonite compound (step 6) is applied and the pollutants are thus immobilized or further washed out (step 12). The process is suitable for the treatment of used materials also containing organic and inorganic pollutants.
