  • Patent number: 6387426
    Abstract: Ammonia is first applied to a meat product to produce an ammoniated meat product. The ammoniated meat product is then contained in a treatment vessel in a treatment gas atmosphere substantially free of ammonia gas. Once the ammoniated meat product is contained in the appropriate atmosphere, the treatment method includes increasing the pressure in the treatment vessel to an operating pressure greater than the vapor pressure of ammonia at the temperature of the ammoniated meat product being treated. The operating pressure is held within the treatment vessel for an operating period effective to reduce the amount of ammonia gas which escapes from the meat product after the product is placed again under atmospheric conditions.

  • Patent number: 6379728
    Abstract: A stream (A) of first foodstuff has a first pH and a stream (B) of second foodstuff has second pH. The first pH and second pH are oppositely related to a third or target pH for the foodstuff such that one pH level is above the target level while the other pH level is below the target level. The two streams (A) and (B) are combined in a proportion to produce a combined or third foodstuff at the target pH. The first pH and second pH are sensed or otherwise determined, preferably on a continuous basis, and then these pH values are used to determine the proportion at which the stream of first foodstuff and stream of second foodstuff are combined and mixed. Particularly, the pH modification can be loosely controlled to produce an over-modification in the first foodstuff and then the stream (B) of second foodstuff may be combined with the stream (A) first foodstuff to produce a stream (C) of material having the target pH.

  • Patent number: 6359214
    Abstract: An EMI gasket (20) includes a plurality of serrations (34) along at least one edge (35, 36). The serrations (34) are arranged side-by-side so that each may be articulated individually. That is, one of the serrations (34) may be displaced significantly out of the plane of the gasket without affecting adjacent serrations. Thus, when the edge of the gasket (20) is compressed between two surfaces which include a discontinuity (40) such as a step or protuberance between them, the serration in contact with the discontinuity is displaced out of the plane of the gasket without displacing adjacent portions of the gasket. Allowing a portion of an EMI gasket (20) to be displaced out of the plane of the gasket without affecting adjacent portions of the gasket substantially reduces or eliminates gaps which occur due to the failure of the gasket to precisely follow the contour of a component.
