Patent CA-2112715-A1 (CA)
Inventor: PENZOTTI ROGER P
IPC: F16F9/04
Filed: 1993-12-31
Abstract: A pneumatically damped vehicle suspension system. The suspension system provides damping which is load-dependent, i.e., the amount of damping varies in approximate proportion to the load supported by the suspension system, thereby maintaining a nearly constant fraction of critical damping over the normal range of operating loads. The damping provided by the system is also frequency-dependent, a characteristic not achievable with hydraulic dampers. Two independent damping circuits provide maximum damping at the suspension's two resonant frequencies, or modes of vibration--the bounce mode and the axle-hop mode. Relatively little damping is provided at other frequencies, resulting in improved isolation of road inputs.

Title: Detecting occlusion of proximal or distal lines of an iv pump
Inventor: NATWICK VERNON R
IPC: F04B43/12
Filed: 1992-08-05
Abstract: A volumetric pump (30) includes a motor (146) that rotatably drives a cam assembly (142), which actuates a plunger (48), causing it to compress a pumping portion (34b) of a flexible tubing (34).  Compression of the tubing displaces fluid trapped within the pumping portion, causing it to flow past an outlet cracking valve (52). A proximal pressure sensor (44) and a distal pressure sensor (56) each produce signals indicative of the pressure within the proximal portion and distal portion of the flexible tubing, which are used to determine whether a proximal or distal occlusion of the flexible tubing has occurred. Both pressure sensors comprise strain gauges connected to flexures that apply a spring-biased force against the proximal and distal portions of the flexible tubing. These sensors thereby respond to the cross-sectional size (diameter) of the tubing, as affected by fluid pressure therein.  Proximal and distal pressures are thus monitored without violating the integrity of the flexible tubing.

Title: Compression boot for treatment of injured limb
Inventor: FARLEY MICHAEL D
IPC: A61D9/00
Filed: 1992-08-20
Abstract: An article for treatment of an injured leg of a horse includes front (2) and rear (4) pivotally attached parts. The two parts form a cavity for receiving the leg when in a closed position and allow the leg to be received or removed when in an open position. In a first embodiment, one portion of the rear part receives the hoof of the leg, and the hoof is captured between lower portions of the front and rear parts as the front part is rotated toward the closed position but before the closed position is reached. In a second embodiment, the hoof of the leg is received by the front part. The capturing of the hoof before the front and rear parts are brought into full engagement allows the injured leg to be placed in tension to set the leg before the leg is fully encased in the inner lining of the article.

Filed: 1994-07-19
Abstract: A spring actuated fastener driving tool has a lift pawl, bearings for supporting the lift pawl for pivotal movement about a first axis into and out of engagement with a power spring, and an operating handle continuously engageable with the bearings and intermittently engageable with the lift pawl. The operating handle is supported by a housing for pivotal movement about a second axis parallel to the first axis through successive driving cycles each including a loading phase during which the pawl remains engaged with the power spring as the power spring is resiliently deflected and loaded, and a release phase during which the pawl is disengaged from the power spring. The housing and the operating handle have guide surfaces which coact in sliding engagement with the bearings to accommodate movement of the bearings towards a reference plane containing the second axis during at least the loading phase of the drive cycles.

Title: Identification and use of protease inhibitors
Inventor: DOVEY HARRY F
IPC: A61K31/40
Filed: 1994-08-08
Abstract: ABSTRACT            .beta.-amyloid peptide (.beta.AP)  production in cell culture and in vivo is inhibited by administering aspartyl protease inhibitors, particularly inhibitors of proteases of cathepsin D.  Useful aspartyl protease inhibitors can be selected in a two-step assay, where test compounds are first screened for aspartyl protease inhibition activity in vitro in non-cellular assays.  Those test compounds which are found to display protease inhibition activity are then tested in cellular assays for .beta.AP production inhibition.  Those test compounds which are capable of inhibiting intracellular .beta.-amyloid production may be incorporated in pharmaceutical compositions.

Title: Portable Radio Communication Device
Inventor: MIZOGUCHI TAMIYUKI
IPC: H04B7/08
Filed: 1995-01-30
Abstract: Electric field intensity of a signal corresponding to a plurality of receivers and received through antennas are converted into direct currents. The converted durect currents thus converted are fed to electric field level detection circuit. The electric field level detection means detects the electric field level on the basis of the direct currents of respective receivers and feeds a detection signal to a control portion. The control portion compares the electric field level corresponding to the direct current value in said controller with a predetermined electric field level to make judgement that the received electric field is a strong electric field and stable. Then, a command is issued to keep one of the receivers, at which the higher electric field level is detected and to turn off other receiver. An electric power source control portion performs switching of the switch portions corresponding to respective of the receivers to supply only one of the receiver from a power source and to block power supply from the power source to other receivers.

Patent CA-2142756-A1 (CA)
Inventor: BULGRIN THOMAS C
IPC: B29C45/78
Filed: 1995-02-17
Abstract: An improved temperature control system using a state controller with two degrees  of  freedom to  regulate  the temperature of the barrel of an injection molding machine is disclosed.  The control system divides the temperature of the barrel  into  longitudinally-extending  zones  and  radially extending layers within each zone.  Heat transfer calculations which include the effects of heat transfer between all the layers within the zones are performed for a set time in the future to accurately determine the heat needed from the heater band to reach the operator set point temperature.  The duty cycle for the heater bands is thus accurately set to give a more responsive and accurate control than heretofore possible. The controller additionally includes factors for accounting for heat  disturbances  present  in  the  injection  molding process.   In addition each system is calibrated for each machine to insure accurate formulation of machine specific parameters such as heat transfer co-efficients used in the control.

Filed: 1995-03-21
Abstract: A fuselage burn-through blocking material includes a layer of a 30 to 300 g/m non-woven material of needled, flame retardant fibres laminated to one or both surfaces of a 100 to 600 g/m mica paper. Mutual attachment of the layers in the laminate isachieved by a partially cross-linked, latently adhesive, heat resistant binder included in the mica paper itself. The process for manufacture of the laminate includes adhesiveconnection of the layers under pressure and at a temperature which does not trigger full cross-linking of the binder. The resulting two or three layer laminate when installed in a fuselage significantly increases the fuselage burn-through time in a post-crash fire to at least 3 minutes.

Title: Protection circuit and method for telecommunication equipment
Inventor: STORBECK CARSTEN
IPC: H02H9/04
Filed: 1995-05-02
Abstract: The present invention relates to a device and method having particular application to protection of telecommunication installations against overvoltage and overcurrent. The method and device (preferably a circuit) utilize overvoltage suppressors, positive-temperature-coefficient (PTC) resistors, and voltage-limiting components. The object of the invention is to develop a method and a circuit for surge-current-resistant, reversible line protection. This is achieved by utilizing an overvoltage suppressor with a response voltage above the peak value of a power supply voltage, a thyristor diode with a voltage response slightly above the maximum operating voltage values of the line being protected, and a PTC resistor, connected between the overvoltage suppressor and the diode, that is used as a decoupling member to block the maximum amplitudes of the power supply voltage, obviating the need for a dedicated fail-safe device.
