  • Patent number: 6899691
    Abstract: A method and apparatus for controlling a fluid separation system in response to fluid pressure changes in a fluid flow, said method comprising the steps of sensing a fluid pressure; comparing the fluid pressure to a threshold value, and if the fluid pressure is below the threshold value, then pausing fluid flow for a selected period. During the selected period, either the fluid pressure sensed automatically resolves or the method further comprises a step of setting a fall alarm condition. The method and apparatus may further include interpreting a particular quantity of below threshold fluid pressure occurrences where the fluid pressure is below the threshold value occurring within a particular time period, and then, signalling an alarm. Threshold values may be calculated by the method or apparatus according to a formula such as the following: Threshold Value=Config+75?0.3309*Qin/(1?Hin)?0.

  • Patent number: 4824339
    Abstract: A peristaltic pump cartridge including a continuous flexible tube having two ends and a portion therebetween providing a U-shaped loop for use with a rotor and rollers to provide a peristaltic pump, a cartridge housing having supports for maintaining the portion of the flexible tube in the U-shaped loop external to the housing, the legs of the U-shaped loop leading into the housing, the housing having apertures through which connecting portions of the flexible tube remote from the U-shaped loop have been threaded from the interior to the exterior of the housing.
