Patent CA-2185759-C (CA)
Title: Surgical clamping mechanism
Inventor: KNODEL BRYAN D
IPC: A61B17/32
Filed: 1996-09-17
Granted: 2007-11-06
Abstract: A surgical instrument which has a frame, an elongated shaft, an end effector with first and second jaws for clamping tissue, a post cooperatively engaged with the proximal end of the second jaw received in a slot on the sidewall of a channel included as part of the first jaw, a pusher member affixed to the proximal end of the second jaw, and an actuator to effect movement of the pusher member from a forward position to a rearward position, is disclosed. When the pusher member moves rearwardly, the post rides in the slot in the sidewall and the second jaw moves from a closed position where it is adjacent the first jaw for clamping tissue to an open position for placing tissue between the jaws. The combination of cooperating elements of the instrument provides a convenient and simple mechanism for clamping or grasping tissue between the jaws. This mechanism decreases the force necessary to clamp the tissue and utilizes more of the effective length of the second jaw. These benefits in turn make it easier for the user of the instrument to clamp tissue and reduces the tendency of the second jaw to flex or twist during clamping, therefore providing the user with even greater control over the surgical procedure. Overall, the clamping or grasping mechanism incorporated into the surgical instrument provides an attractive alternative to the conventional prior art mechanisms for accomplishing these functions.
Patent CA-2191549-C (CA)
Inventor: SHIMIZU YASUO
IPC: G08G1/16
Filed: 1996-11-28
Granted: 2002-02-26
Abstract: In a power assisted vehicle steering system, an actual traveling direction of the vehicle, and a tangential direction of a road on which the vehicle is traveling are detected, and the actuator for the steering system is controlled so as to reduce or minimize a deviation of the actual traveling direction of the vehicle from the road tangential direction. Thus, a supplemental steering torque is produced so as to force the direction of the vehicle into agreement with the direction of the road so that the effort required for the vehicle operator to maintain the vehicle on the road can be reduced or can be even eliminated, and the lateral stability of the vehicle is improved both on straight roads and curved roads.

Title: Wax hydroisomerization process
Inventor: APELIAN MINAS ROBERT
IPC: C10G73/38
Filed: 1995-10-13
Granted: 2006-06-06
Abstract: This invention discloses a process for producing a high Viscosity Index lubricant having a viscosity of at least 125 from a waxy hydrocarbon feed having a wax content of at least 40 wt%. The process comprises catalytically dewaxing waxy paraffins present in the feed primarily by isomerization, in the presence of hydrogen and in the presence of a low acidity large pore zeolite molecular sieve having a crystal size of less than 0.1 micron, an alpha value of not more than 30 and containing a noble metal hydrogenation component. The large pore zeolite is preferably zeolite beta loaded with 0.3 to 2 wt% Pt. The feed may be hydrocracked prior to dewaxing with the large pore zeolite. The effluent of the process may also be further dewaxed by either solvent or catalytic means in order to achieve target pour point. The products obtained from the process of the present invention are high VI, low point materials obtained in high yield. These products are highly stable, both oxidatively and thermally and to ultraviolet light. Improved product yields are obtained.

Title: Systems and methods for making time-sequential measurements of biological events
Inventor: PANESCU DORIN
IPC: A61B5/308
Filed: 1996-02-14
Granted: 2003-06-17
Abstract: Analog or digital systems (10) and methods generate a composite signal derived from a biological event in a time sequential fashion. A first set of signals derived from a biological event using a first group of sensors (20) during a first time interval is input.     A second set of signals derived from the biological event during a second time interval sequentially after the first time interval using a second group of sensors (36) is input. The second group of sensors has at least one common sensor that is part of the first group and other sensors that are not part of the first group. The first and second sets of signals are time aligned using signals sensed by the at least one common sensor, thereby generating the composite signal. The time alignment is done by shifting the first and second sets of signals either with or without computing a time difference between them.

Title: Cylindrical alkaline battery
Inventor: IWAKI HIROFUMI
IPC: H01M50/51
Filed: 1997-10-07
Granted: 2001-12-11
Abstract: A cylindrical cell is disclosed which is so constructed that an insulating ring (12) is seated on the outside of the sealed part of the opening part of a cell case (1), the terminal face of a negative electrode plate (9) is depressed below the outer face of a facing label (10) covering the insulating ring (12), and a gas discharge hole (8) formed in the negative electrode plate (9) is concealed with the insulating ring (12). This construction prevents the cell from allowing flow of a current to an adjacent cell and consequently from being charged by the adjacent cell. Since the cell uses a thermally shrinkable insulating facing member, it enjoys improved reliability of the outer covering. Even if a plurality of such cells of the construction described above are used as arranged in series and part of the cells are erroneously connected with the direction of polarity thereof reversed to the remaining cells, the possibility of the reversely connected cells allowing flow of current to the remaining cells and consequently being charged by the remaining cells will be precluded and the possibility of the device in use being smeared or harmed by the electrolyte otherwise suffered to leak when the reversely connected cells are charged by the remain-ing cells will be eliminated.

Filed: 1996-06-06
Granted: 2009-04-28
Abstract: The present invention provides novel compositions and methods useful in cancer therapy for inhibiting the multidrug resistance phenotype, which often thwarts long-term chemotherapeutic regimens. The novel compositions of matter comprise oligonucleotides targeted to the human MDR1 and MRP genes, which inhibit expression of these genes, thereby rendering tumors and other forms of cancer more susceptible to the cytotoxic effects of chemotherapeutic agents.  Oligonucleotides are also provided that inhibit the multidrug resistance phenotype by exerting an aptameric effect.

Abstract: An alignment tool is provided for aligning collecting plates of an electrostaticseparator in substantially a common plane. The alignment tool includes a pair ofelongated alignment members, at least one of which is of a convex configuration. The collecting plates, including any misaligned collecting plates, are sandwiched between the alignment members with the convex surface of one of the alignment members opposing the collecting plates. The convex member is then brought to a parallel position by forces applied to opposite ends thereof, and the alignment members are temporarily clamped in generally parallel relationship to each other which maintains the collecting plates aligned in a generally common plane. Thereafter, a rod of a permanent clamping mechanismhaving a plurality of loops is rested atop either of the alignment members and rotated to bring the loops into and through gaps between adjacent collecting plates. A second rod is passed through the loops and thereafter the alignment members are released and the clamping members retain the collecting plates in aligned relationship.

Granted: 2001-11-20
Abstract: A method of and system for detecting the possible fraudulent use of a telecommunications network involves applying rule-based criteria to generate a plurality of fraud alarms, each corresponding to an individual rule. Each alarm is associated with a particular customer, and for each individual customer a note is made of the total alarms generated by that customer and the grouping of individual alarm types generated. The customer's call is then determined to be fraudulent or otherwise based upon prior experience of past customers who have generated that particular profile of alarm grouping and total number of alarms. The system automatically outputs a list of potentially fraudulent customers, the accounts of which may either be further investigated or may automatically be inhibited.
