Title: Controlled flow rate intravenous apparatus employing shape-memory flow-control element
Inventor: KRUMME JOHN F
IPC: F16K31/02
Filed: 1983-11-24
Granted: 1987-09-17
Abstract: A unitary disposable conduit extends from the intravenous reservoir along a gravity-flow path to the patient, and incorporates a valve block containing an externally controlled flow-control valve. An electronic controller monitors the drop rate in a drop chamber which is an integral part of the disposable conduit, compares this rate with an operator-selected rate, and controls the valve by varying the current in a shape-memory actuator element whose movements, caused by the resultant Joule heating, are coupled to the valve to proportionally vary the flow rate in the conduit. The valve block is securely received within a recess in the controller, and is automatically coupled to the controller when inserted within this recess. The shape-memory actuator element may be incorporated within the disposable valve block, or may form a part of the controller, with a simple mechanical coupling to transmit its movements to the valve. The valve may be automatically or manually closed when the valve block is removed from the controller, or if power failure occurs.

Abstract: In a measuring instrument for measuring the relative position of two objects, the graduation of a scale as well as a number of identical reference marks absolutely positioned with respect to this graduation and associated code marks are scanned by a scanning unit. The periodic scanning signals obtained in the scanning of this graduation are transferred via first signal lines, and the reference signals obtained in the scanning of the reference marks are transferred over a second signal line to an evaluating arrangement. Code signals obtained in the scanning of the associated code marks by the scanning unit are also transmitted over the second signal line to the evaluating arrangement. The reference signals and the code signals on the second signal line are distinguished from one another by means of AND gates which ensure that the reference signals and the code signals are present on the second signal line only during respective predetermined signal states of the periodic scanning signals.

Abstract: This invention relates to a system for monitoring, in a cavity in the earth, the position of, or changes in the position of, an interface between two immiscible liquids of different densities. In accordance with the invention, two pipes, one positioned within the other to form a space between them, extends into the cavity in the earth. A probe is mounted on the outer wall of the inner pipe and is vertically positioned near the interface to be monitored. The probe includes an emitting source and a detector-receiver and readings are taken of signals received by the detector after emission by the source and at least partially reflected by at least one of the liquids. From the readings the position of or change in interface may be computed since the signal reading will vary as a function of the relative position of the probe and the interface. The invention may be applied to the monitoring of excavations of underground salt cavities.
