Patent CA-2167285-A1 (CA)
Title: Methods for conveying objects through apparatus, packing apparatus and methods for packing materials in cartons
Inventor: MOSSE RICHARD W E
IPC: B31B50/02
Filed: 1994-07-13
Abstract: Objects such as cartons (16) supported in transport holders (110), are carried on a first conveyor wheel (140) and transferred to a second conveyor wheel in respective transfer operations.  Each conveyor wheel has circumferential spaced recesses for carrying such objects, each recess containing a moveable magnet (156) for holding a said object.  The wheels run tangentially to one another so that each object on the first conveyor wheel during each transfer operation is momentarily simultaneously in recesses of the first conveyor wheel and of the second conveyor wheel.  Transfer is triggered by the timed withdrawal of the magnet holding the object in the recess of the first conveyor wheel by a cam (170) leaving the object held by the magnet of the second conveyor wheel.  Cartons may be bottom sealed, filled and top sealed on respective conveyor wheels.

Patent CA-2170841-A1 (CA)
Inventor: KUZMAK LUBOMYR I
IPC: A61B17/02
Filed: 1996-03-01
Abstract: A blunt laparoscopic dissector device is provided which includes an elongate dissector element including a "finger-like" flexible distal end portion. A cylinder or barrel member disposed at one end of a pair of pivotable control arms provides rotatable mounting of the dissector element. A control assembly, including a control rod connected to the other control arm and extending along the length of dissector element, exerts a force on the dissector element so as to produce the desired curvature of the flexible distal end portion. A locking mechanism maintains the force on the dissector element so as to maintain the desired curvature. Rotation of the dissector element within the cylinder enables a surgeon to effect control of the movement of the tip thereof while holding the device in a comfortable stationary position.

Title: Composite or integral metal structural post for the erection of two interior walls
Inventor: BLAZEVIC DRAGO
IPC: E04C3/292
Filed: 1996-05-21
Abstract: A composite structural post is provided for two interior walls of a building.  In one embodiment, such post includes a rectangular wooden stud having four faces. An elongate "L"-shaped metal angle bar or a "T"-shaped metal angle bar is secured to the rectangular wooden stud by means of a first arm of the elongate "L"-shaped metal angle bar or the leg of the elongate "T"-shaped metal angle bar which is secured to a first face of the rectangular wooden stud. A second arm of the elongate "L"-shaped or "T"-shaped metal angle bar is free and unsecured and projects from the rectangular wooden stud.   The first arm of the elongate "L"-shaped metal angle bar or the leg of the elongate "T"-shaped metal angle bar is provided with means to enable securing a first interior wallboard stud thereto by means of self tapping screws. The arm of the elongate "L"-shaped or "T"-shaped metal angle bar, which is free and unsecured and projects from the rectangular wooden stud, is provided with means to enable securing a second interior wallboard or interior sheathing thereto by means of self-tapping screws. The second interior wallboard or interior sheathing is disposed at right angles to the first interior wallboard or interior sheathing. In another embodiment, an integral metal structural post is provided for the erection of two pairs of interior walls. Each such pair of walls includes interior walls which are disposed at right angles to one another. The integral metal structural post includes a first elongate metal angle bar having an "L"-shaped cross-section, and two arms which have a particularly recited structure. A  second identical elongate metal angle bar is arranged in mirror-image relationship to the first elongate metal angle bar. An elongate metal web interconnects the two elongate metal angle bars in a particular manner. Because of the particulary-recited structures of the arms of the elongate metal angle bars, an interior wallboard or interior sheathing is secured directly to respective ones of the four interior faces of the two elongate metal angle bars. When such securing is effected, two interior corners are created.

Abstract: Un réseau de communications (1) comprend plusieurs noeuds de réseau (2, 3, 4, 5) reliés par des voies de transmission (6, 7, 8). Un gestionnaire de réseau (9) commande l'acceptation des appels sur ces voies de transmission en classant les appels entrants et en choisissant dans la base de données (14) une répartition appropriée de débits binaires moyens à maxima. Avec la charge de voie de transmission surveillée, cette répartition choisie permet de déterminer une répartition ultérieure reflétant la charge. La décision d'accepter ou rejeter un appel intervient en fonction de cette répartition ultérieure grâce à un algorithme d'acceptation d'appels tenant compte par exemple de la largeur de bande efficace.

Title: Gas mixing apparatus for a ventilator
Inventor: MERRICK EDWIN B
IPC: A61M16/20
Filed: 1996-02-06
Abstract: The gas mixing apparatus (10) provides the components of a breathing gas for mixing at approximately ambient atmospheric pressure, and regulates the pressure of a selected gas to approximately ambient atmospheric pressure for mixing with air at ambient atmospheric pressure. The gas mixing apparatus (10) includes a piston (26) disposed within a pump chamber (12). A flow limiting inlet (46) controls introduction of a first selected gas such as oxygen for mixing with a second selected gas such as air. The pressure of the first selected gas is limited to an acceptable maximum pressure, so that even if a valve (54) for admitting the first selected gas for mixing at ambient pressure fails, breathing gas will not be provided at an excessive pressure. A demand valve (68) is alternatively provided for reducing the pressure of the first selected gas supplied before mixing, but a pressure sensor (74) is also provided downstream of the demand valve (68) for detecting failure of the demand valve (68), to shut off the supply of the first selected gas to prevent overpressurization.

Title: Apparatus and method for focus control
Inventor: CESHKOVSKY LUDWIG
IPC: G11B7/125
Filed: 1996-12-05
Abstract: Control apparatus and method are disclosed for shifting focus on a multilayered optical medium using closed loop servo operation. The outputs of an astigmatic optical pickup are independently modified by a control signal generator according to a predetermined time varying pattern to produce a deceptive error signal that changes the apparent focal offset seen by a servo circuit. While in closed loop mode, the servo tracks the shifting apparent focal plane from a first information layer of the medium toward a second information layer. Thereafter the control signals are removed, and the servo locks focus on the second information region.

Title: Production of oriented plastics by roll-drawing
Inventor: AJII ABDELLAH
IPC: B29C55/18
Filed: 1997-01-08
Abstract: A process and apparatus for the continuous solid state forming of semicrystalline polymers using roll-drawing is disclosed.  The output of an extruded thick polymer profile is stabilized by a gear pump.   The profile is passed through a die for the desired geometry and a cooling calibrator.   The profile is heat conditioned in heating tunnels to a temperature below the melting point prior to deformation between sets of rolls.  A plurality, e.g. four pairs of rolls apply both compression and tension to the polymer profile.  The tension applied on the profile, the roll  gap,  the  linear  speed  of  the  profile  and  its temperature are monitored and controlled for the amount of polymer deformation and relaxation allowed.  High tensile modulus  and  strength,  both  in  the  longitudinal  and transverse  direction  of  the  polymeric  strip,  can  be achieved.

Title: Inhibitors of farnesyl-protein transferase
Inventor: ANTHONY NEVILLE J
IPC: C07D401/02
Filed: 1995-09-27
Abstract: The present invention comprises analogs of the CAAX motif of the protein Ras that is modified by farnesylation in vivo. These CAAX analogs inhibit farnesylprotein transferase. Furthermore, these CAAX analogs differ from those previously described as inhibitors of farnesyl-protein transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.
