    • A medical infusion pump is disclosed which provides for greatly improved accuracy in the delivery of medicaments to a patient. Among the various features included in the instant invention is a pumping body which serves to deform and reform a tube so as to maintain the initial cross-section thereof and thereby preserve the output accuracy of the pump. Also disclosed with regard to the pumping body is a wholly mechanical synchronization of the pumping body and valves associated therewith and coactive with the aforementioned synchronization a mechanical linearization of output of the pumping body per each pumping cycle. Additionally, several features which serve to enhance the utility of the instant invention are also included therein among which is an associated assembly operative to automatically load or disload a tube or IV set into or out of the pumping body. Associated with the assembly operative to automatically load or disload a tube and disclosed herein is an assembly operative to selectively open or close a slide clamp associated with the tube in such a way as to ensure that the tube is occluded such that in combination with the valves associated with the pumping body, a condition of free-flow of medicament is never realized. Additionally disclosed are sensor housings adapted to measure various quantities associated with fluid flowing through the tube wherein the housings are with associated components adapted to achieve a substantially normal orientation with respect to the sidewall of the tube and in the achieving of such normal orientation, expressing an essentially zero elastic stress gradient across the tube.

    • A method of monitoring and controlling a pumped well having a rod string extending from a pumping unit located at the earth's surface to a subterranean pump, the rod string being sequentially reciprocated through up and down strokes and the well producing pumped fluid through a collection pipe, the method includes measuring the displacement and the load on the rod string, determining the well is pumped-off when fluid flow from the well substantially stops, recording the maximum load on the sucker rod string during pumped-off conditions, the load being measured during a selected portion of the first portion of the rod string downstroke, establishing a target pumped-off load as a selected percentage of the measured load, periodically initiating a pumping cycle, terminating each pumping cycling when the rod load equals the target rod load. The well is pumped in cycles with each pumping cycle terminated as above described and in which the time spacing between pumping cycles is selected by the well fill-time determined by measuring the rod load during a portion of the first portion of a downstroke following each of a succession of short pauses in the pumping action until the measured rod load approaches the point where it is substantially stabilized, indicating the fluid level in the well is near an equilibrium point, which measured fill-time is then thereafter used as the delay time between each pumping cycle.

    • A self-contained system to continuously monitor a mechanism used to process, control or regulate fluid flow or pressure and provide a continuing indication of the status or condition of the monitored mechanism. A specific form of the invention employs a low frequency sonic-to-electrical transducer that monitors opening and closing of a disk-type steam trap. The detected sonic signal is processed and sent to a microprocessor that is programmed to develop a time-based, baseline data set representative of normal operation of the steam trap in the environment in which it operates. The baseline data set is compared with the data from on-line operations of the steam trap. As the environment and the steam trap operation change during normal on-line operations, the baseline data set is updated to change with the changing environment and the changing steam trap operation.

    • A method of monitoring and controlling a well pump apparatus having an electric motor that rotates a crank arm having a counterweight thereon, a pivoted walking beam oscillated by the crank arm which reciprocates a sucker rod and a pump between an upstroke and a downstroke. The electric current from the motor is measured periodically between the peak upstroke motor current and the peak downstroke motor current, and the results are then integrated to deduce an analysis current per stroke. The mean of a number of sequential samples of the analysis current per period is calculated and thereafter the standard deviation is calculated. The last sample will be within two standard deviations of the mean or the results will be discarded and new data gathered. The well pump apparatus is stopped if a selected number of consecutive samples fall below a preselected threshold.
