Patent number: 7060482Abstract: The present invention is directed to thermostable xylanase enzymes are suitable for feed pelleting applications. The novel xylanase enzymes comprise at least 40% of their optimal activity from a pH range from about pH 3.5 to about pH 6.0, and from about 40 to about 60° C., and exhibit at least 30% of their optimal activity after a pre-incubation step for 30 minutes at 70° C. in the presence of 40% glycerol. Also disclosed are modified xylanase molecules comprising either a basic amino acid at position 162 (TrX numbering), or its equivalent position in other xylanase molecules, at least one disulfide bridge, or a combination thereof. The thermostable xylanase molecules of the present invention have a physiological temperature and pH optima and are useful as animal feeds additives since they can withstand the heat associated with feed sterilization and pellet formation, yet they exhibit optimal activity within an animal to aid in breakdown of ingested feed.Type: GrantFiled: November 16, 1999Date of Patent: June 13, 2006Assignee: National Research Council of CanadaInventors: Wing L.

Patent number: 7061236Abstract: A metal detector has a circular excitation coil (10) through which foodstuffs to be tested (65) pass, on a conveyor belt (40). The excitation coil (10) is excited by a stable oscillator (50) and the lines of flux generated by the excitation coil (10) link two receiver coils (20, 30) equidistantly spaced either side of the excitation coil (10). As a foodstuff (65) having a foreign ferromagnetic or electrically conductive object therein passes through the receiver coils (20, 30), a voltage is induced in them. This induced voltage is phase compensated. The change in amplitude or frequency of the oscillator (50) as the foodstuff (65) moves through the excitation coil (10) is also passed to the processor (70) which removes the artifacts from the detector signal caused by the volume of the foodstuff (65) itself. The resultant signal, which was previously swamped by the effect of the volume of the foodstuff itself, can then be detected and the foodstuff can be removed from the conveyor (40).Type: GrantFiled: March 6, 2001Date of Patent: June 13, 2006Assignee: Thermo Electron CorporationInventor: Andrew Michael Britton
