Title: Coulage de bande
Inventor: KATO HEIJI
IPC: B22D11/06
Filed: 2000-04-07
Abstract: L'invention concerne une machine (11) de coulée à deux tambours qui produit une bande (12) laquelle suit un cheminement (10) de transit passant à travers un élément (14) à rouleaux pinceurs, éventuellement un laminoir (15) à chaud puis sur une table (17) de sortie pour aboutir à un poste (19) d'enroulement comprenant deux enrouleurs (85, 86) commutables. Une cisaille (81) placée avant le poste d'enroulement permet de couper la bande (12) en tronçons discrets qui peuvent être déviés par des déflecteurs (82, 84) de positionnement, et envoyés ainsi sur une table (83) de sortie menant à un récipient (87) de ferraille. Ce système permet de couper la bande et de la transformer en ferraille lorsque qu'elle présente des défauts ou en cas de mauvais fonctionnement de l'installation sans interrompre la coulée en continu, et de diriger à nouveau la bande vers le poste d'enroulement lorsque le problème est réglé.

Inventor: FLURY URS
IPC: B66B9/04
Filed: 2000-05-08
Abstract: The invention relates to a hydraulic elevator installation, comprising a counterweight, in which a cylinder (5) can be displaced along a piston rod (2). Said piston rod can be connected in a fixed manner to sections (1) of a building. The cylinder (5) has two pressure chambers (6, 7), between which hydraulic oil can be circulated, using a pump (9). This process displaces the cylinder (5) along the piston rod (2). The movement of the cylinder (5) is transmitted to a cabin (20) by means of a cable (21) which is guided over deflection pulleys (22, 23). In this assembly, the cylinder (5) forms part of the counterweight in relation to the cabin (20). According to the invention, the pump (9) and a motor which drives the same (12) are fixed to the cylinder (5) in such a way that these also function as part of the counterweight. The invention enables the complete hydraulic unit to be pre-assembled at the factory stage, to avoid maintenance work such as filling and air bleeding at the installation site. The invention can be advantageously used for elevator installations in buildings.

Patent CA-2371011-A1 (CA)
Inventor: TEXTOR MARCUS
IPC: A61L27/34
Filed: 2000-04-28
Abstract: Multifunctional, polyionic copolymers are synthesized on/or applied to substrate surfaces for analytical and sensing purposes, the coatings being particularly useful for suppression of non-specific interaction, adsorption or attachment. Groups can be coupled to, integrated into or absorbed to the multifunctional polymer that are able to recognize, interact with and bind specifically to target analyte molecules. These materials can also be used to modulate biological interactions upon substrate surfaces for use as selective implant surfaces that resist cell attachment and may optionally promote the attachment of specific cell types or induce a particular cellular behaviour.  The multifunctional polymer coatings typically include brush copolymers based on a polycationic or polyanionic backbone with side chains that control interaction with the environment, such as poly(ethylene glycol) or poly(ethylene oxide)-based side chains that decrease cellular adhesion, and analyte-specific side chains.

Title: Portable, self-contained apparatus for deep vein thrombosis (dvt) prophylaxis
Inventor: MORRIS JOHN K
IPC: A61H7/00
Filed: 2000-05-16
Abstract: An entirely self-contained, patient-worn apparatus for deep vein thrombosis (DVT) prophylaxis, and other conditions includes an inflatable/deflatable bladder (102) disposed against an extremity such as the upper calf (109), foot, or hand of a patient, or within a cast. An inelastic member (106, 108)  is preferably used to fully enclose the bladder and body part, such that compressive forces are directed substantially entirely against the body part  of the patient when the bladder (102) expands, thereby conserving the power and reducing the volume of pneumatic compression required to operate the device. Given this conservation of energy, the invention may be battery operated from a source immediately proximate to the bladder arrangement, enabling the entire device to be self-contained and, in fact, worn by the patient. The reduced volume also allows the use of miniaturized components including the compressor motor and compressor.
