Abstract: ABSTRACT                  FLUID LEVEL MEASUREMENT SYSTEM           (with reference to Fig. 2 of the drawings) In a fluid level measurement system for the measurement of the level of fluid  (12) in a vessel  (10) the electrical impedance (Z1) of a first conduction path between a central  rod electrode  (18)  and a surrounding cylindrical electrode (100) and the electrical impedance (Zx)  of a second conduction path between  the cylinder  (100)  and the  vessel  (10)  are  established.   The  first  conduction  path  is restricted to be below the minimum fluid level (16) by an insulating coating (19) on the rod (18); the second conduction path varies with fluid  level.   An  output  signal  is  extracted  from the electrodes potentiometrically and is indicative of fluid level.  The signal may be  linearized  by  application  to  a  circuit  having  a  matched non-linear transfer function.          The system overcomes the problem of providing a continuous output signal indicative of level, which to date has only been possible by combination of outputs from discrete level sensors.

Abstract: ABSTRACT METHOD FOR ESTIMATING POROSITY AND/OR PERMEABILITY     In a drill stem test,  a packer is set in the well bore to isolate a potential producing zone.  A drill pipe with a down hole valve is fitted through the packer.  The pipe is usually partially filled with a liquid column prior to commencement of the test. which essentially comprises opening the valve so that formation fluids can flow into the drill pipe and measuring various parameters associated with the fluid transfer.  A method for estimating porosity and/or permeability includes the steps of setting up such a drill stem test wherein flow of formation fluid to a drill pipe may be controlled by a down hole valve, opening the valve to establish a flow, recording flow parameters, and analysing oscillatory transients in the flow to compute therefrom estimates of porosity and permeability.

Abstract: METHOD FOR DETECTION OF PERITONEAL INFLAMMATION OR INFECTION                    James L. Babb Timothy G. Bloomster Jon  A. Rudbach Abstract Peritoneal inflammation or infection can be detected in a patient by assaying a peritoneal lavage sample from the patient for lysosomal enzymes.  This is done by combining the lavage sample with a leukocyte lysing agent and a chromogenic or fluorogenic enzyme substrate specific for lysosomal enzymes.  The lysosomal enzymes can then be measured, and the inflammation or infection detected, by measuring the color or fluorescence developed in the sample by action of the enzymes on the substrate.

Granted: 1989-01-17
Abstract: ABSTRACT OF THE DISCLOSURE      A pulsator for milking machines has two diaphragms connected by a rod with each diaphragm dividing a pressure chamber into a processing space and a damping space. The damping spaces communicate through a channel that is provided with a throttle. The processing spaces are connect-ed either to a source of vacuum or to the atmosphere. A switchover is attached to the rod and connects lines leading to the pulsation spaces of milking containers either to the atmosphere or to a source of vacuum.  A main line is provid-ed with a throttle. The throttles in the communicating channel and in the main line are detoured by bypasses provided with chokes that can be vacuum-activated through control channels. To improve the known pulsator by eliminat-ing the sensitive hoses and timers and to allow adjustment of the duration of the stimulation phase with no need for a timer, the control channels are always in communication with one of the control chambers in a control disk, one chamber constantly communicating with the vacuum source and the other chambers subject to atmospheric pressure. The disk can be rotated by a transmission, which is driven by the rod as it travels back and forth, in such a way that the control channels are connected either to the control chamber that is subject to vacuum or to one of the control chambers that are subject to atmospheric pressure.

Abstract: ABSTRACT OF THE DISCLOSURE     Instead of the usual three or five valves a valve manifold includes four valves, namely a pair of line block valves intersecting a longitudinally extending flow passage in the valve body for normally closing inlet passages, an equalizer valve between the line block valves intersecting the flow passage; below the equalizer valve is a vent passage and a vent valve in the vent passage.  During operation the line block valves are open to promote the flow of process pressure to the measuring instrument and the equalizer valve is closed to prohibit the flow along the longitudinally extending flow passage.  The vent valve is in the open position.  By closing the line block valves with respect to the inlet passages, while leaving them open with respect to the flow and outlet passages, closing the vent valve and opening the equalizer valve permits the flow to be balanced between each side of the manifold.  Upon opening the vent valve the manifold can be vented.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to methods for operating auto-matic test equipment (ATE) for printing circuit boards (pcbs), and in particular to a method of providing guarding during mea-surements made by such equipment on the components of circuits on such boards.  In testing pcb components connection is made, by activation of a selection of an array of probes, to circuit nodes surrounding a component to be tested.  By applying input signals to some nodes and extracting outputs at others, the performance of a component may be examined in relation to that expected to see if it is sound or faulty.  In some circuits the performance of a component may not be as expected, even though it is sound, due to the influence of surrounding components.  In this case, it is known to place guards, i.e. to apply further signals via probes to further nodes, so that such disruption may be minimized and a measurement obtained consistent with a sound component.  An ATE with an automatically generated test routine is seldom able to be used without modification, and the final step involves an operator who, running the program on a known to be good board, identifies which sound components are being failed and modifies the program until known good boards pass consistently.          According to the present invention a method for defining guards during the operation of an ATE so that a selected component of a circuit may be tested includes the steps of:  establishing a measurement of the selected component, identifying a circuit node associated with the selected  component, applying a guard  to the node, establishing a measurement with the selected guard in place and, should the guard result in an improvement, retaining the guard during subsequent automatic testing.

The controller responds to requests from a plurality of ports on the controller, connected to computers or similar devices, for connection to selected ones of a plurality of channels connected to the data retrieval devices.  The connect request is decoded by the controller, and if the requested channel is available, the controller will interconnect the two devices.  The controller allows simultaneous access by any of the ports to any of the channels not being used by another port.  The device is in modular form so that a single design can be configured to efficently operate in different applications.  The controller is cascadable to allow larger numbers of devices to be connected.  Only four serial data lines are necessary for interfacing with each computer and storage device making the installation of the connections relatively easy and economical.
