Title: Snowmobile suspension system
Inventor: BOIVIN DENIS
IPC: B62M27/02
Filed: 1999-09-17
Abstract: A snowmobile suspension system used to suspend the drive belt of a snowmobile between extended and retracted position is described herein. The snowmobile suspension system is provided with a pair of side rails to guide the drive belt, a pair of suspension arms each having a proximate end pivotally mounted to the snowmobile and a distal end pivotally mounted to both side rails, shock absorbers and compression springs provided between the side rails and the snowmobile to bias the side rails towards their extended position, and a progressive spring assembly mounted to the side rails to prevent forceful contact between the side rails and the undersurface of the snowmobile. The side rails are advantageously made of composite material and present a concave undersurface. The pivotal attachment of the distal end of the rear suspension arm to the side rails is advantageously made via an adjustable cam assembly allowing the user to modify the characteristics of the snowmobile suspension system.

Patent CA-2288924-A1 (CA)
Inventor: TURNER DAVID
IPC: F02D41/22
Filed: 1999-11-04
Abstract: An electronic throttle assembly uses a torque motor and mechanical system to position the throttle. The assembly is configured to keep the throttle slightly open during times of electrical power failure to the torque motor. Inherent electromagnetic qualities of the torque motor provide a reluctance torque that varies depending on internal stator/rotor geometry and is present in the absence of electrical power to the motor. A mechanical system provides a counter torque. Aligning the throttle to the desired slightly open position at a point where the reluctance torque is countered by the mechanical torque, allows an engine controlled by the throttle to continue to operate even if electrical power to the torque motor is lost.

Title: Robot feature tracking devices and methods
Inventor: VILLEMURE DENIS
IPC: B23K26/042
Filed: 1999-12-17
Abstract: Motorized slides are inserted between the end of a robot arm and a robot tool/sensor arrangement to provide additional positioning ability. A control unit of the slides cooperates with the control unit of the sensor to maintain the tool correctly positioned over a feature while the robot arm moves following a programmed path. The control unit of the sensor has look-ahead and additional buffers from which corrected information is determined to compensate for robot teaching inaccuracies, calibration and robot arm response errors. A sensor with two distinct probing zones is used to get information about the position of the tool tip and of the feature to assist in calibrating the sensor/tool relation.

Title: Information transmission in a telecommunications system
Inventor: RINNE MIKKO J
IPC: H04J3/00
Filed: 1998-08-18
Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel or independent signalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling. The parameters of the selection rule used in the logical channel selection can include, for example, the effect of the use of the logical channels on the quality of service of the connection which uses the traffic channel, the current usage rate of the logical channels, the number and priority of messages to be sent, and an estimate of the number and priority of messages to be sent in the near future.

Abstract: A water leakage protector apparatus for appliances subject to leakage includes a first device (90) for detecting water leakage from the water supply line (50, 52) coupled to the appliance and a second device (28) for detecting water leaking from the appliance itself. A control apparatus (10) is coupled to a valve, disposed within the water supply line (50, 52), is connected to a source of electrical power (12), and controls the water flowing to the appliance. The appliance is connected to the control apparatus (10) to obtain electrical power for operation. The first (90) and second (28) sensing devices are coupled to the control apparatus (10) so that when a water leak is detected by either the first (90) or the second (28) detecting device the control apparatus (10) stops the water from flowing in the water supply line (50, 52) and interrupts electrical power to the appliance.

Patent CA-2309458-A1 (CA)
Inventor: MCBURNETT JAMES R
IPC: F16N13/20
Filed: 1999-09-28
Abstract: In order to protect bearings which support the journals of pumping gears, hydraulic gear pumps have operating parameters restricted by temperature.  Typically, these pumps do not operate at temperatures above about 210 ~F.  There is, however, a need for hydraulic gear pumps which can pump hydraulic fluid having a temperature which may be as high as about 250 ~F without adversely affecting the bearings. In order to pump hydraulic fluid at these temperaturers, the present invention connects the return line of the system in which the pump is used to a lubrication chamber at one end of a journal supporting one of the pumping gears. The hydraulic fluid which has been cooled by the heat exchanger is then drawn by low pressure in a low pressure region of a pump inlet opening, through an interface between bearings supporting the gear journals and the gear journals themselves. In this way, bearings and gear journals are lubricated with hydraulic fluid having a temperature substantially lower than hydraulic fluid in a return line or tank.

Title: Heterodimeric fusion proteins useful for targeted immune therapy and general immune stimulation
Inventor: GILLIES STEPHEN D
IPC: C07K14/54
Filed: 1998-12-08
Abstract: Disclosed are methods for producing fusion proteins with the heterodimeric cytokine, interleukin-12. In order to insure that the proper ration of fused and non-fused subunits are obtained in the fusion protein, a specific stepwise approach to genetic engineering is used. This consists of first expressing the non-fused p40 IL-12 subunit in a production cell line, followed by or simultaneously expressing in the same cell, a second recombinant fusion protein consisting of the fused polypeptide linked by a peptide bond to the p35 subunit of IL-12. Molecules containing the p35 fusion protein cannot be secreted from the transfected mammalian cell without first complexing in a one to ratio with the p40 subunit, thus ensuring the production of active heterodimeric fusion proteins.

Abstract: An actuator having a housing with a pivot opening therein. An actuator handl e has a pivot pin extending from an end thereof for connecting the handle to a crank which  includes a drive pin. The handle is assembled to the housing with the pivot pin extending through the pivot opening. A bushing may be disposed between the pivot pin and the pivot opening to take up tolerances between the parts and provide smooth handle rotation. The drive pin on the crank extends into a drive slot on a slider which translates within the housing to actuate a wind ow locking mechanism. The drive slot is generally pear-shaped with, preferably symmetrical, oppose d cowed sidewalls along which the drive pin rides during rotation of the handle. The slider ma y further include a pair of fulcrum tabs disposed on a top thereof adjacent opposite sides of the dri ve slot for contacting a side surface of the crank during rotation of the handle to provide mechanica l advantage at the handle. A spring is provided with a bowed middle portion which extends benea th the slider and identical ends which extend above the slider at each side thereof. One end o f the spring provides the detent function by biasing the. drive pin against one of the slider side  walls. The other end of the spring extends upward to provide pick resistance by forming a physical barrier between a slot in the base portion of the housing and the crank, handle, and bushing. The actuator may be converted for single-point use, by providing a single point extension on the  slider, either integrally or as a separate part. The single point extension has a latch opening for receiving a latch of a single-point locking mechanism during rotation of the handle. The latch opening may be defined by a pair of symmetrically curved arms which force the latch into the openin g, and which provide non-handedness.
