Patent CA-2019055-C (CA)
Title: Parallel signal path
Inventor: NETH ALOIS
IPC: H04J3/08
Filed: 1990-06-15
Granted: 1996-07-02
Abstract: When transmitting digital signals using time-division multiplexing via a transmission link with repeaters at which time slots are either only branched or also re-injected, the problem arises of continuing to maintain the transmission of information even when an alarm is triqgered in a repeater.  The present invention provides a bypass circuit via which the repeater is bypassed when an alarm is triggered therein.  If a re-injection of time slots is provided, the bypass circuit can thereby trans-mit a message to the adjacent repeaters and/or line terminal equipment in order to permit the injection of time slots not re-injected in the repeater.  If the time-division multiplex signal contains a service channel, messages can be transmitted via this channel to the adjacent repeaters and follow-up measures can be initiated.

Title: Tourniquet for regulating applied pressures
Inventor: MCEWEN JAMES ALLEN
IPC: A61B5/03
Filed: 1990-07-12
Granted: 2002-11-05
Abstract: A tourniquet comprising: (a) an occlusive band for encircling a limb of a subject and for applying pressure to the limb wherein an inner surface of at the band faces the limb; and applied pressure sensing means located at a predetermined position on the inner surface of the band for producing an indication of the pressure applied by the band to the limb near the predetermined location. The applied pressure sensing means is comprised of material having a degree of flexibility and physical dimensions selected so that the sensing means conforms closely to the surface of the occlusive band and does not substantially displace the surface of the limb away from the band surface. The applied pressure sensing means produces an applied pressure signal representative of the pressure applied by the band to the limb near the predetermined location, the occlusive band is responsive to a variable pressure control signal, and pressure-regulating means responsive to the applied pressure signal is included for producing a pressure control signal to maintain the pressure applied by the band to the limb near a predetermined reference pressure.

Title: Apparatus and method for subcuticular stapling of body tissue
Inventor: GREEN DAVID T
IPC: A61B17/03
Filed: 1991-08-13
Granted: 2002-01-15
Abstract: A surgical apparatus is disclosed for attaching adjacent end portions of cutaneous body tissue wherein a pair of opposed jaws have means for moving the jaws toward and away from each other. Body tissue engaging means in the form of sharp tip members extend from each jaw and toward the other so as to engage the opposed portions of cutaneous tissue when the jaws are positioned thereagainst and moved toward each other. The jaws and the tips are arranged to cause the cutaneous tissue to assume an irregular shape at the interface whereby an elongated rod-like member, preferably rectangular in cross section, may be directed generally medially of the interface of the tissue to attach the opposed portions to thereby permit healing. The elongated member may have indentations to improve retention within the tissue. A tapered distal end of the elongated member has a pointed tip to facilitate penetration into the tissue.

Patent CA-2056826-C (CA)
Inventor: DEFATTE ROBERT G
IPC: E05F3/10
Filed: 1991-12-02
Granted: 1995-05-30
Abstract: A mounting plate enables the bracket of a conventional door closer to be removably retained to a door casing or the like.  The mounting plate has a pair of tabs that define slots for slidingly receiving the flanges of the closer bracket.  A stop permits entry of the closer bracket into the mounting plate slots from only one direction and also limits sliding in that direction.  Bumps on the mounting plate cooperate with the closer bracket mounting holes to loosely restrain the closer bracket from sliding out of the mounting plate in the other direction.  After the mounting plate is secured to the door casing or the like, the closer bracket is slid into the mounting plate slots, and the closer bracket functions in a completely normal manner.  When the closer bracket must be removed to provide full utilization of the door opening, it is necessary only to slide the closer bracket out of the mounting plate.          Later, the closer bracket is replaced to its operational position by sliding it back into the mounting plate slot.

Granted: 2001-02-06
Abstract: Un système de commande de téléphone (1) améliore sensiblement l'accessibilité des abonnés du système en prévoyant une variété de modes de manipulation d'appels et prévoit en outre divers moyens de programmation à l'aide desquels les abonnés peuvent adapter le système en fonction de leurs besoins. En fonctionnement, un numéro téléphonique unique et individuel (NUMERO D'ACCES) est affecté à chacun des abonnés, ce numéro pouvant être composé à partir de n'importe quel emplacement par l'intermédiaire du réseau téléphonique public (PSTN) (2). Le système de commande détermine à quel abonné est destiné un appel et, par référence à une base de données, détermine le procédé de manipulation de l'appel qui a été présélectionné par cet abonné (par exemple commutation d'un appel sur un autre numéro de téléphone). La fonction de commutation (4) peut être prévue dans le système de commande lui-même, ou, dans une variante, peut se situer dans le réseau PSTN mais sous la commande du système de commande. De cette manière, le NUMERO D'ACCES peut être utilisé comme unique numéro téléphonique pour un abonné. Les appelants n'ont pas besoin de connaître le lieu spécifique où se trouve l'abonné et n'ont pas à savoir également quels sont les divers numéros téléphoniques spécifiques à un lieu, tel que la maison, le bureau, le téléphone de la voiture etc.

Title: Damping system for structure stabilization system
Inventor: TAMEZ FEDERICO GARZA
IPC: F16F9/18
Filed: 1992-05-29
Granted: 1997-09-30
Abstract: A damping subsystem protects a structure from the effects of seismic disturbances and employs at least a first pair of first and second damping and transformation mechanisms including respective, associated first dampers oriented in parallel relationship in a first direction and oppositely disposed relatively to the center of gravity of the structure and mechanically connected between respectively corresponding portions of the structure and the foundation in relatively inverse relationship.  Each mechanism transforms a force transferred to the associated first damper from the foundation in the first direction and/or any lateral, relative displacement of the corresponding structure and foundation portion in the first direction to a corresponding force and/or displacement, respectively, in a second direction perpendicular to the first direction, each also performing the reverse transformation.  A mechanical interconnection between the first and second damping and transformation mechanisms transfers any such transformed force and/or displacement of the second direction from one to the other of the pair of first and second damping and transformation mechanisms, thereby to impede rotation of the structure relatively to the foundation.  The respective, associated first dampers of the pair of mechanisms provide individually controllable damping of lateral displacement between the corresponding structure and foundation portions in the first direction.
