Inventor: CONRAD HANS-ROLF
IPC: D21G1/00
Filed: 1995-03-21
Abstract: A method and apparatus for processing a web of material, which is dispensed from a roll and fed through at least one roller gap of a roller-gap system which includes a processing station, an unrolling station on the input side of the processing station, and a roll magazine on the input side of the unrolling station which magazine includes at least one roll storage position. When rolls of web material are processed, the processing delay times lead to an uneven distribution of the temperature and/or moisture within the roll which in turn causes nonuniformity of the results in the processing station. The web of material still on the roll is exposed, prior to being unrolled, to a preselected atmospheric environment for a predetermined minimum length of time. Accordingly, the roll storage position is located in a chamber, the atmosphere of which can be controlled to a preset temperature and/or humidity level.

Title: Prosthetic joint cup and insert therefor
Inventor: TSCHIRREN ERNST
IPC: A61F2/36
Filed: 1995-05-04
Abstract: The cup (2) made of a titanium-aluminum alloy is set into the acetabulum. It is thicker on one side (7) than on the opposite side (8).

Inventor: FRANCOEUR NORMAND
IPC: A47L13/16
Filed: 1996-04-25
Abstract: A flexible cleaning pad for removing dry particles such as lint, dust and the like from surfaces such as clothing, upholstery and the like. The pad has a hand contacting sheet made of flexible material and an opposed cleaning sheet also made of flexible material. Both the hand contacting sheet and the cleaning sheet are adhesively fixed to an intermediate core sheet by an adhesive material. The core sheet is made of a substantially rigid yet bendable material presenting resilient properties. The adhesive material is chosen so as to also presents reselient properties. A strap extending across the hand contacting sheet allows the pad to be secured in the palm of the hand of an intended user. The core sheet provides structural rigidity to the pad while allowing the latter to be bended. The core sheet also allows the pad to spring back to a substantially flat configuration when no external force is applied to the pad. The use of an adhesive material having resilient characteristics allow the hand contacting sheet and the cleaning sheet to slide relatively to the core layer when the pad is bended thus preventing warping of the latter.
