Patent number: 6115936Abstract: The device consisting of a hollow body made of foam rubber or other shock absorbing material defining an enclosed chamber and having a plurality of holes therein. A closeable opening is provided that is of adequate size to allow wet tennis shoes or other objects in need of drying to be placed inside said enclosed chamber. The unit with the articles to be dried within are inserted into a rotary drum clothes dryer and the loud thumping and banging noise normally associated with drying heavy shoes in a rotating metal drum are significantly reduced or eliminated. Further, the padding and shock absorbing shape of the envelope prevents the dryer's door from being knocked open from the inside as often happens when hard shoes hit the back of the door during the tumbling and drying process. Furthermore, shoes and delicate fabrics may safely be dried in the same load as they are effectively separated by the device.Type: GrantFiled: August 16, 1999Date of Patent: September 12, 2000Inventor: Daniel Arlie

Patent number: 6035549Abstract: A method for closely protecting materials (10) sensitive to contamination by airborne contaminating agents and placed on a work surface (P). At least one decontaminated gas stream (1, 2) is fed from either side towards the materials in a direction substantially parallel to the work surface, and each gas stream (3) leaves the work surface in an intermediate area between the edges of the work surface and in a direction substantially perpendicular thereto. Alternatively, at least one gas stream is fed towards the materials from above the work surface at an intermediate area between the edges thereof, and in a direction substantially perpendicular thereto, and each gas stream leaves the work surface in a direction substantially parallel thereto and on either side of the materials.Type: GrantFiled: January 16, 1998Date of Patent: March 14, 2000Assignee: Ultra Propre Nutrition Industrie Recherche (U.N.I.R.)Inventors: Mathieu Chevalier, Christophe Chevalier
