Patent number: 6190723Abstract: Thioredoxin, a small dithiol protein, is a specific reductant for major allergenic proteins present in widely used foods from animal and plant sources. All targeted allergenic proteins contain disulfide (S—S) bonds that are reduced to the sulfhydryl (SH) level by thioredoxin. The proteins are allergenically active in the oxidized (S—S) state. When reduced (SH state), they lose their allergenicity. Thioredoxin achieved this reduction when activated (reduced) either by NADPH via NADP-thioredoxin reductase (physiological conditions) or by dithiothreitol, a chemical reductant. Skin tests and feeding experiments carried out with sensitized dogs showed that treatment of the food with reduced thioredoxin prior to ingestion eliminated or decreased the allergenicity of the food.Type: GrantFiled: March 23, 1998Date of Patent: February 20, 2001Assignee: The Regents of the University of CaliforniaInventors: Bob B. Buchanan, Karoly Kobrehel, Boihon C. Yee, Rosa Lozano, Oscar L. Frick, Richard W. Ermel

Patent number: 6190727Abstract: A spray application apparatus and method, well suited for use in a plywood production resin spray line, provides automatic control of the spread rate of resin applied to the veneer layers built-up to form plywood panels. In lieu of the conventional trial and error method of manually adjusting the height of a spray nozzle to adjust the spread rate, a controller, actuator, and various sensors are utilized in conjunction with a novel control algorithm to achieve continuous automatic spread rate control. The control effectively compensates for variations in process parameters (e.g., resin flow rate, conveyor line speed and veneer temperature) during a production run, whereby product quality is increased with reduced resin consumption. The controller is easily and effectively calibrated without the need to obtain accurate initial values of the variable process parameters.Type: GrantFiled: October 30, 1998Date of Patent: February 20, 2001Assignee: Georgia-Pacific CorporationInventor: Charles E.

Patent number: 6190764Abstract: An inductive write head includes a first pole and a second pole that form a yoke having a write gap between the first pole and second pole. The second pole is formed of a particular Co100-a-bZraCrb compound. More specifically, the second pole is formed where “a” is in the range of about 2 atomic percent to about 18 atomic percent, and “b” is in the range of about 0.5 atomic percent to about 6 atomic percent. The magnetic write element also includes a conductive coil which lies between the first pole and the second pole. The inductive write head also includes a first yoke pedestal attached to the first pole, and a second yoke pedestal attached to the second pole, with the write gap formed therebetween. Further, the first yoke pedestal has a pedestal width that defines the write element trackwidth and that is smaller than the pedestal width of the second yoke pedestal.Type: GrantFiled: November 23, 1998Date of Patent: February 20, 2001Assignee: Read-Rite CorporationInventors: Zhupei Shi, Chun He, Syed Hossain, Mark S.
