  • Patent number: 5852357
    Abstract: A system for controlling an Alternating Current (AC) signal to an AC powered device. The system uses a microcontroller to monitor the cycles of the AC signal supplied to the AC powered device. By utilizing cycle counting, the microcontroller can supply various numbers of waveforms to the AC powered device in order to adjust the speed and/or energy supply level to the AC powered device. At full power, all the cycles of the AC signal are provided to the AC powered device. If the speed and/or energy supply level of the AC powered device needs to be reduced by half, the microcontroller supplies every other cycle of the AC signal to the AC powered device.

  • Patent number: 4718896
    Abstract: A flow controller is provided that detects intervals between successive drops and responds to detection of intervals which are too long by shutting down operation of the administration set if the abnormal flow causing the long interval cannot be corrected. In response to detection of abnormal flow which is not clearly a high flow condition and/or an empty container, the flow controller sequentially opens, closes, re-opens and again closes the clamp of the controller in an attempt to restore normal flow. If normal flow is restarted before the sequence is completed, the controller returns to normal control of the fluid flow. Otherwise, completion of the sequence results in a shutdown of the system and activation of an alarm. In keeping with the invention, indicia are provided in connection with the drop chambers of the administration sets which are sensed by sensing means mounted to the drop detector of the flow controller in order to indicate to the controller the size of the orifice in the drop chamber.

  • Patent number: 4375231
    Abstract: A repair construction and method are disclosed for repairing a damaged portion in the wall of a tire. A patch is installed over the damaged portion on the inside of the tire, and the inside of the tire is pressurized to force the patch into the damaged portion, preferably in a concave shape. The remainder of the plug area then is filled on the outside of the patch with a suitable plug material, and the plug material and patch are then cured while the patch is maintained in position at least partially within the damaged portion. This construction and repair method eliminates bulging on the exterior of the tire after the repair is completed.
