Title: Method and inflatable chamber apparatus for separating layers of tissue
Inventor: CHIN ALBERT K
IPC: A61B17/00
Filed: 1996-12-27
Abstract: This invention is an apparatus for tissue dissection and instrument anchoring, including a dissection balloon (512) having a viewing window (508) at its distal end, or including an anchoring dissection balloon having a non-uniform elasticity selected to achieve desired inflation shape and pressure characteristics. The window, which can be a wide angle lens, is transparent and sufficiently strong to retain a desired optical shape while being pushed against tissue layers by a rigid instrument (515) deployed within the balloon. In preferred embodiments, the instrument includes a long necked dissection balloon deployed through a cannula, and a housing (513) to which the dissection balloon's mouth is attached. In accordance with a method of use of the invention, the distal end of the balloon is inserted between tissue layers and inflated to dissect the tissue layers.
Patent CA-2243224-A1 (CA)
Inventor: PILDNER REINHART KARL
IPC: G08B25/14
Filed: 1998-07-15
Abstract: The invention provides an alarm panel connected to a telephone line. The alarm panel comprises a microprocessor connected to a circuit which operates in two states: passive and active. In the passive state, the alarm panel monitors the line for a ring signal and tests the integrity of the telephone line. In the active state, the alarm panel seizes the telephone line and provides full bi-directional communication with a receiver through the telephone line. The circuit is designed such that the individual subcircuits for each state operate independently of each other and can be modified to meet various regulatory requirements without affecting the other circuits. The circuit draws low current in the passive state. Finally, the circuit is separated from the microprocessor using only 2 or 3 optocouplers.
Patent CA-2248364-A1 (CA)
Inventor: PEER FERDINAND
IPC: A61B90/50
Filed: 1998-01-07
Abstract: The invention relates to an instrument for the manipulation of fine structures, said instrument detecting hand tremor and compensating for this hand tremor by effecting counter-movements of the working tip.      The main area of application will probably lie in the field of microsurgery, since the operations performed in said field can be made difficult by the hand tremor of the operating surgeon. Here, the tremor is detected by movement sensors, by repeated analysis of the position of the handheld part (1) of the instrument, or by deriving electromyographie signals from the forearm of the operator. Intentional and unintentional movements are differentiated from one another on the basis of one or more criteria, such as movement amplitude, speed, frequency and direction. To compensate for undesired movements, signals are sent to an arrangement of actuators (3) which cause deflections of the movable part (4) of the instrument, which deflections at the tip of the instrument compensate for the hand tremor. When the instrument is used as a needle holder in surgery, the actuators (3) can also be controlled by push button in such a way that, by oscillations, they facilitate the penetration of the suture needle into the area being worked on.

Abstract: Un joint d'alignement, une porte à chariots et une méthode de jonction permettant de relier et d'aligner mutuellement les extrémités de deux rails de voies et ponts suspendus de section fermée avec ouverture dans l'arrête inférieur permettant le transfert de chariots d'une rail à l'autre par l'intermédiaire d'une section de rail. Le joint permet de relier et d'aligner une section de rail coupée à angle aux extrémités à deux rails dont l'extrémité jointe est aussi coupée à angle. La section de rail centrale et les deux rails forment une surface de roulement continue et uniforme. L'emboîtement des quatre cotés de la section des rails créé par le joint offre des surfaces d'appui pour la section centrale et les deux extrémités de rails en regard, dans lesquelles sont disposés des boulons capables de transmettre les efforts de séparation aux éléments du joint. Le joint permet un mouvement relatif et limité de la section centrale et des rails joints dans la direction longitudinale tout en assurant un alignement des rails. Le mouvement relatif est limité à l'espace entre deux rails que peut supporter un chariot sans compromettre son roulement efficace d'un rail vers l'autre. L'utilisation de la section centrale amovible pour joindre les deux rails permet d'insérer ou d'enlever des chariots sans désassembler les rails de leurs composantes de suspension ou de leurs embouts.

Title: Method and apparatus for continuous winding of a web of material
Inventor: MADRZAK ZYGMUNT
IPC: B65H19/30
Filed: 1999-02-24
Abstract: Process and winding machine for the continuous winding of a web of material onto a reel spool to form a reel. The process includes forming a winding nip between a peripheral zone of a reel drum the reel, guiding the material web over the peripheral zone of the reel drum, positioning the reel in a secondary zone, and displacing and pressing the reel drum against the reel in the secondary zone. In this manner, one of control and regulation of a linear force in the winding nip occurs through the displacement of the reel drum. Upon obtaining a completed reel having a desired reel diameter, the process includes moving the reel drum into a temporarily fixed position, introducing a new, empty reel spool into a primary zone, forming another winding nip between the new reel spool and the reel drum through a relative movement of the new reel spool with respect to the reel drum in the temporarily fixed position, cutting the material web, winding the material web onto the new reel spool to form a new reel, and removing the completed reel. The process also includes transferring the new reel spool from the primary zone to the secondary zone, releasing the reel drum from the temporarily fixed position, and displacing the reel drum for one of the control and regulation of the linear force in the winding nip between the reel drum and the new reel spool in the secondary zone. The winding machine includes a reel drum arranged to form a winding nip with the reel, a primary mount adapted to hold a new reel spool, wherein the primary mount is further adapted to displace the new reel spool along a first guide path substantially radially to the reel drum, and a secondary mount coupled to the reel spool. The machine also includes a pressure device coupled to the reel drum, which is adapted to move the reel drum at least substantially horizontally when the reel spool is in the secondary mount, and which is further adapted to at least temporarily fix a position of the reel drum when the new reel spool is in the primary mount.

Title: Table leg wire management apparatus
Inventor: GUTGSELL DAVID R
IPC: A47B21/00
Filed: 1999-04-29
Abstract: A furniture leg wire management apparatus is configured for use with a furniture leg formed by opposite leg posts separated by a gap. The apparatus includes a legway defined by an elongated tubular body. The body includes a forward portion and opposite clamping arms that are resiliently deflectable toward each other. The clamping arms are deflected when the legway is pushed into the gap between the leg posts and provide an outwardly directed force to clamp the legway in this operative position. The tubular body further includes a central rib terminated in a rear flange. The central rib divides the legway into two wire/cable channels, while the rear flange cooperates with the clamping arms to define opposite elongated slots. The slots communicate with the two cable channels to provide an avenue to feed the wires/cables into a corresponding channel. The wire management apparatus further includes a decorative cover plate that is removably mounted on the legway to improve its aesthetics.
