  • Reticulated cellulose producing acetobacter strains
    Patent number: 6429002
    Abstract: Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production. A method and media for producing bacterial cellulose under agitated culture conditions resulting in sustained production over an average of 70 hours of at least 0.1 g/liter per hour are achieved. A unique reticulated cellulose product is produced using the methods and conditions claimed, and may be converted to of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Preferred Acetobacter strains are ATCC Nos. 53264, 53263 and 53524.

  • Knife with removable blades
    Patent number: 4391043
    Abstract: A knife including a detachable blade which is readily released from the knife handle with a locking mechanism including a spring biased pivotally mounted locking plate formed with a locking tab mating with a recess in a knife blade tang.To assemble the blade to the handle the tang is inserted into a knife handle socket and the locking plate tab moved into locking engagement with the tang. Depression of the locking plate rearend enables quick release for replacement or removal of the knife blade. A series of angled shoulders formed on the knife blade and the tang cooperate with corresponding angled surfaces on the handle components provide great rigidity of the blade in the handle.
