Patent number: 5552320Abstract: A self-contained biological indicator includes an outer container that is translucent and liquid impermeable. The container is normally closed by a vapor-permeable, micro-organism-impermeable closure and contains a source of viable microorganisms, a culture medium, a composition that decomposes hydrogen peroxide, and a detector that undergoes a visible change in response to growth of the microorganisms. In operation, the indicator is first subjected to a sterilization cycle in a hydrogen peroxide sterilizer. Without opening the outer container, the microorganism source, culture medium, and hydrogen peroxide-decomposing composition are brought into contact. The indicator is placed in an incubator, after which the detector responds to any microorganism growth, indicative of incomplete sterilization.Type: GrantFiled: March 16, 1995Date of Patent: September 3, 1996Assignee: Johnson & Johnson Medical, Inc.Inventor: Daniel F.

Patent number: 5543164Abstract: This invention describes new water-insoluble protein-based edible coatings and films having improved barrier and mechanical properties, and methods for their preparation from water-soluble proteins. In the invention, aqueous protein solutions are denatured with heat, chemicals and/or enzymes to induce thiol-disulfide interchange and thiol oxidation reactions, thereby forming new intermolecular and intramolecular disulfide crosslinkages. The formation of covalent intermolecular crosslinkages in protein-based edible films and coatings results in films having improved barrier and mechanical properties which are insoluble in water. Water-insoluble emulsion film systems can be formed by incorporating lipids into the denatured aqueous protein matrix.Type: GrantFiled: June 17, 1994Date of Patent: August 6, 1996Assignee: The Regents of the University of CaliforniaInventors: John M.

Patent number: 5538747Abstract: The invention proposes the damping of grain, for example, by creating a rotating layer (20) in a damping chamber (2) with the help of acceleration rotors (3). For this, the cross-section of the rotation chamber is designed to form an outer boundary around two or, preferably, three acceleration rotors (3, 3', 3"). In this way, the rotating layer is forced into an eccentric and spiralling motion within the damping chamber (2). Damping is carried out in a very gentle manner, so that there occurs hardly any abrasion and no grain damage. Additional advantages include a longer and controllable reaction period during damping, optimized preparation for milling and a shorter, controllable tempering period.Type: GrantFiled: June 22, 1994Date of Patent: July 23, 1996Assignee: Buehler AGInventor: Roman Mueller
