Title: Freewheel clutch
IPC: F16D43/02
Filed: 1978-11-23
Abstract: A clutch, for use in driving an ink-ribbon mechanism in a teleprinter, has an outer drum 1 which is driven and which contains an inner drum 2 connected to the output shaft 4. Rotation of the outer drum in one direction causes the shaft to rotate by virtue of rollers 8 interposed between the interior of the outer drum and wedges 6 attached to the inner drum. Once a given torque is exceeded, the wedges yield against internal springs 7 and the rollers pass over to opposite wedges on the other side. The shaft can now only be driven in the reverse direction and is subject to a similar torque limitation. <IMAGE>

Title: Improvements in intravascular catheters
IPC: A61M25/01
Filed: 1979-07-31
Abstract: Intravascular catheters 1 of flexible plastics or elastomeric material have localised inside the distal tip thereof a radio-opaque metallic component 3.

Title: Method and apparatus for monitoring and controlling a resistance welding operation
IPC: G11B15/61
Filed: 1981-02-26
Abstract: A resistance welding controller for dynamically controlling both weld current and weld time in order to achieve a desired  DELTA R value. The resistance across the weld electrodes is monitored by the controller during the heat-up phase of the weld and compared to target values for minimum resistance (Rmin) and rate of resistance change (dR/dt). If the observed values for Rmim and dR/dt bear a predetermined relationship to the target values, a dynamic correction is made in the percentage heat control setting. The weld is then continued at the revised weld current level until the desired  DELTA R value is satisfied. If upon weld termination, the observed weld time is greater than the target weld time, an additional correction in weld current is made in preparation for the next weld. In addition, the controller is also adapted to detect newly dressed weld electrodes and automatically respond by reverting to the original weld schedule.
