Title: Method for batch annealing of austenitic stainless steels
Inventor: KIM YEONG-U
IPC: C21D9/54
Filed: 1998-04-10
Granted: 2003-05-11
Abstract: Methods are provided for annealing coils of austenitic stainless steels through the use of a batch annealing process. The preferred methods involved selecting compositions of austenitic stainless steel alloys having a sufficiently low weight percentage of carbon so that annealing of the austenitic stainless steel occurs without intergranular carbide precipitation at a temperature of less than about 1700 DEG F, which is well below the normal annealing temperature for austenitic stainless steels. The lower annealing temperatures allow for annealing in conventional batch annealing furnaces. The content of carbon in T-201L stainless steel was kept at less than 0.030 weight percent and the steel was successfully annealed at temperatures within a range of about 1650 DEG F to about 1700 DEG F. The carbon content of T-304L stainless steel was kept at less than 0.015 weight percent and the steel was successfully annealed at temperatures within a range of about 1550 DEG F to about 1700 DEG F. For light gauge strip, the winding tension of the coiled stainless steel was reduced prior to the batch annealing process. In particular, winding tensions of less than about 30,000 psi were beneficial, with good results being found when the winding tension was held within the range of about 15,000 psi to about 3,000 psi.

Title: Method of cutting the selvedge
Inventor: SCARI DIEGO ARMANDO
IPC: D03D47/40
Filed: 1998-07-30
Granted: 2002-06-21
Abstract: The present invention concerns a method of cutting the selvedge on the weft insertion side on a rapier loom operating with one weft thread supply bobbin. The conventional method of cutting the selvedge presently in use on rapier looms implies the necessity of forming a false selvedge on the weft insertion side which then is severed from the edge of the fabric and thus constitutes a considerable waste of material the economic importance of which increases with the value of the threads processed. The present invention proposes to eliminate this loss of material and to simplify the loom design. These objectives of the present invention are attained by completely eliminating the formation of a false selvedge and by cutting each weft thread as soon as it is beaten up while it is subject to a tensioning action by a holding device (13). In this manner fabrics woven from one weft source can be produced provided with a perfect selvedge without wasting material and using one scissors (14) device only instead of two as used according to the state of the art.

Title: Sulfur removal process from an acrylate waste stream
Inventor: GARZA MARTINIANO JR
IPC: C07C67/08
Filed: 1998-10-28
Granted: 2001-12-01
Abstract: Broadly, the present invention is directed to a process for the removal of sulfur from an acrylate waste stream. In particular, disclosed is a process for the recovery and reuse of an acid catalyst employed primarily in the reaction of acrylic esters. During the reaction of acrylic acid and an alcohol in the presence of an acid catalyst, the product acrylate and water are removed from the remaining reaction by-products (heavy ends and oligomers). These by-product heavy end components which include the acid catalyst employed in the reaction process, are directed to an evaporator. The residue stream therefrom is then contacted with water in an extractor. Upon contact with water, a phase separation occurs between the acid catalyst/water mixture and other organic matter. The organic matter is discarded while the acid/water mixture is recycled to the reaction process. The present invention employs the use of an evaporator and an extractor to aid in the separation of the acid catalyst from the reaction by-products waste stream. This removal of acid results in fewer organic sulfur components to be emitted from the reaction process and hence is a more environmentally friendly process.
