  • Continuous food impregnation
    Patent number: 4183963
    Abstract: A continuous method of impregnating food material such as vegetables, fruit, meat, eggs, and fish wherein pieces of the food material are immersed in a concentrated solution, such as brine, syrup, meat curing solutions, humectant solutions and mixtures thereof, said pieces being initially buoyant in said solution and being passed together with said solution along a flow path to a separation zone wherein the impregnating solution flows downwards at a rate greater than the rate of flow of the food material whereby those pieces of food material which, by absorption of the desired quantity of impregnant, have lost sufficient of their buoyancy in the surrounding impregnating solution to be carried downwards by the said solution, are continuously separated from pieces of food material which have absorbed less than the desired quantity of impregnant.

  • Resin and method for removing antimicrobials from body fluids
    Patent number: 4174277
    Abstract: Microporous anionic exchange and non-ionic adsorbent resins which are capable of adsorbing an antibiotic and which have been coated with a non-ionic detergent are disclosed. When contacted with bacterially infected body-fluid specimens, the disclosed resins remove antibiotics from the specimen while exhibiting diminished bacterial adsorption. A combination of a disclosed detergent-coated non-functional adsorbent resin with a cationic resin removes other bacterial inhibitors, as well as antibiotics, from bacterially infected body fluid specimens while permitting the bacteria to remain in the specimens. By removing bacterial inhibitors while sparing the bacteria, the disclosed resins make possible rapid isolation and identification of an infecting organism.

  • Chipper roller and knives therefor
    Patent number: 4164329
    Abstract: A chipper roller for a two-stage grinding machine has removable circular knives spaced axially and circumferentially in an array following a helical path of two turns about the surface of the roller. Each knife is in the form of a disc with a central aperture for accepting a fastening element and with a cutting edge on one side adjacent its periphery and an annular groove on the same side adjacent said edge creating a rake which cooperates with the walls of the groove to produce curls from chunks of material. The knives are fastened to the roller in recesses with only a minor portion of the knife projecting above the surface of the roller. Upon dulling of the exposed edge the knife can be rotated to bring a sharp section of the cutting edge into operation.
