Title: Stapling Plier
Inventor: FEALEY WILLIAM S
IPC: B25C5/02
Filed: 1994-04-05
Abstract: A stapling plier has a magazine adapted to contain a supply of detachably interconnected staples, and resiliently biased driver and clincher arms pivotally connected to the magazine for movement between open and closed positions.  The magazine has an exit throat and the driver and clincher arms are provided respectively with driver and clincher element. An operating lever is pivotally connected to the clincher arm and has arcuate surfaces in sliding contact with complimentary arcuate surfaces on bearings journalled for rotation on the driver arm. Pivotal closure of the operating lever causes closure of the driver and clinching arms, with an accompanying ejection of a staple from the magazine by the driver element and a clinching of the thus ejected staple against the clinching element.
Patent CA-2124085-A1 (CA)
Inventor: GEARING DAVID P
IPC: C07K19/00
Filed: 1992-11-20
Abstract: A receptor protein comprising a gp130 polypeptide linked to a single-chain leukemia inhibitory factor receptor (LIF-R) polypeptide is capable of binding both oncostatin M and leukemia inhibitory factor (LIF). The receptor protein binds LIF with greater affinity than does the single-chain LIF-R polypeptide alone. The receptor may be produced as a fusion protein in recombinant cells. The gp130 polypeptide binds oncostatin M, but with lower affinity than does the inventive receptor protein.

Patent CA-2136232-A1 (CA)
Title: Testing process for the quality control of electromagnetically actuated switching devices
Inventor: NOE ERNST-LUDWIG
IPC: G01R31/00
Filed: 1993-05-18
Abstract: In switching devices in which current contacts are made by actuating a magnetic armature, the test may include an analysis of vibrations or sound emitted in operating conditions. According to the invention, the sound emitted by the switching device when it is actuated is detected by a sensor and transmitted to an evaluation device for the discrimination of the time and/or frequency curve of individual sound components. It is possible in particular with the proposed process to discriminate between the sound signals produced by the making of the contacts and the armature. In addition, a sound analysis in the suitable time range permits a classification of any faults in the switching device. Finally, with particular reference to its application to flashing signal relays, it is possible to obtain an objective determination of the "proper sound" of the relay. In all cases it is especially the high sound components which are evaluated.

The biological tissue is positioned into a photon migration path inside the optical medium (12) to create a tissue medium optical path. The optical medium (12) is adapted to limit substantially escape of photons from the tissue.      The processor (35) determines tissue properties based on the detected optical property of the tissue-medium optical path and the selectable properties of the optical medium (12).

Title: Instrument cluster gauge assembly
Inventor: JOSHI BHAVESH HARIPRASAD
IPC: G12B11/04
Filed: 1995-08-22
Abstract: An instrument cluster gauge includes a pointer assembly and a gauge movement.  The gauge movement has a staff with a constant diameter.  The pointer assembly includes a bushing intended to be placed over the staff when the pointer assembly is mounted on the gauge movement. The bushing has a bore having a lead-in portion providing radial clearance with the staff; a main contact portion with a slight interference with the staff; and a clearance portion providing radial clearance with the staff.  The geometry just described facilitates the mounting of the pointer assembly on the gauge movement to a predetermined depth rather than to a predetermined force.  Further, the assembly force is defined by design and is therefore more consistent than where a pointer assembly is mounted on a gauge movement staff to a target force. Also, the lead-in eases assembly of the pointer assembly onto the staff, facilitating flexible manufacturing.  The bushing further has a face with a stippled surface.  The stipple on the face of the bushing facilitates the use of machine vision in the mounting of the pointer assembly on the staff.

Title: Method and apparatus for control of lung ventilator exhalation circuit
Inventor: O'MAHONY JOHN J
IPC: A61M16/20
Filed: 1995-09-06
Abstract: Patient airway baseline pressure levels are controlled  in  a  ventilator  having  a  pneumatically controlled exhalation valve without an external supply of pilot  pressure,  by  supplying  an  internal  source  of controllable pilot pressure for operating the exhalation valve.  The pressure of pressurized air supplied by an internal pump can be electrically controlled by pulse width modulation of a variable pulse duration signal.  A second source of pressurized air for pilot pressure is provided, and in one embodiment is a reservoir provided for receiving pressurized air from the pump and from the exhalation circuit.   A valve is connected to the pump means and the reservoir for receiving pressurized air from the pump in a first position, and for receiving pressurized air from the reservoir in a second position. When  the  valve  means  is  in  the  second  position, pressurized air is delivered at a pressure which is the greater of the pressurized air supplied by the pump means or the gas flow from the exhalation circuit.

Patent CA-2165981-A1 (CA)
Title: Transmission d'energie a rapport variable
Inventor: CRABB STEVEN MARK
IPC: F16H3/46
Filed: 1994-06-24
Abstract: L'invention concerne une tansmission se présentant sous la forme d'une boîte de vitesses dans laquelle le rapport de transmission entre les arbres d'entrée et de sortie peut varier en continu entre un maximum et un minimum. La transmission comprend une première roue conique (40) montée rotative en liaison avec un élément (32) en forme de U, sur un premier axe (34). L'élément (32) en U peut pivoter autour de l'axe (34) et il est accouplé à la roue conique (44) par un couplage à roue libre (36). De cette manière, le mouvement de pivotement de l'élément (32) en U, dans une première direction autour de l'axe (34), provoque un couple qui s'applique à la roue conique (44) via le couplage à roue libre (36), alors que les pivotements de l'élément (32) en U dans la direction opposée n'ont pas d'effet sur la rotation de la roue conique (44) par l'intermédiaire du couplage à roue libre. Une seconde roue conique (50) est également accouplée avec l'élément (32) en U par un second couplage à roue libre (38) qui fonctionne dans la direction opposée à celle du premier couplage à roue libre (36). Un organe actuateur (52) est accouplé mécaniquement à l'élément (32) en U par un accouplement rotatif (63). La rotation de l'organe actuateur (52) autour d'un second axe (60) produit un mouvement orbital de l'accouplement rotatif (63) qui, à son tour, provoque un mouvement de pivotement oscillant de l'élément (32) en U autour du premier axe (34). En faisant varier le rayon orbital de l'accouplement rotatif (63), l'angle de pivotement de l'élément (32) en U peut varier, de sorte qu'un couple de sortie transmis par les roues coniques (44, 50) peut être modifié indépendament du couple d'entrée appliqué à l'élément de commande (52).
