Patent CA-2017517-A1 (CA)
IPC: C09K8/94
Filed: 1990-05-24
Abstract: A foam is provided for use in a subterranean oil-bearing formation for reducing and controlling the mobility of a gaseous drive fluid.  The foam is generated using an inert gas and a fluorocarbon surfactant solution in admixture with an amphoteric  or  anionic  hydrocarbon  surfactant  solution.    A relatively  small  amount  of  the  fluorocarbon  surfactant  is operative, when mixed with the hydrocarbon surfactant and foamed, to generate a foam that has better stability when in contact with oil than a foam made with hydrocarbon surfactant alone.

Title: Method of reducing noise in a borehole electromagnetic telemetry system
Inventor: KLEIN JAMES D
IPC: E21B47/12
Filed: 1990-06-21
Abstract: METHOD OF REDUCING NOISE IN A BOREHOLE ELECTROMAGNETIC TELEMETRY SYSTEM            Abstract of the Disclosure A  borehole  telemetry  system has  a  transmitter located  in  the  borehole,  a  surface  receiver,  and surface signal sensors for receiving the transmitted signal.     There  are  usually  plural  sources  of electromagnetic noise at a well site which degrade the usefulness of the telemetry system.  The method places noise  sensors  where  the  reception  of  noise  is maximized.  Simultaneous measurements are taken of the ambient noise with the noise sensors and the signal sensors.  The relationship between the measurements of the  noise  and  signal sensors is determined.    The transmitted  signal  is  then  received  by  the  signal sensors and simultaneous measurements of the ambient noise are made by the noise sensors.  The noise portion of the transmitted signal as received by the signal sensors  is  determined  from  the  simultaneous  noise measurements  and  the  determined  relationship.    A received signal having reduced noise is then produced by removing the noise portion.

Title: Low current switching apparatus having detent structure providing tactie feedback
Inventor: ZUERCHER JOSEPH C
IPC: H01H13/50
Filed: 1991-02-27
Abstract: Abstract of the Disclosure Pivotal movement of a switch actuator (16) drives a finger (16c,16d) projecting from the actuator against a convexly bowed leaf spring (40), depressing an intermediate portion of the leaf spring to an unstable concave condition. The leaf spring resists the actuator movement, initially with an increasing force but changing to a decreasing force at a predictable point (B) in actuator movement to provide tactile feedback at an operator (22) affixed to the actuator.  The leaf spring is a flat beam.  The spring force and point of changeover can be readily and predictably varied during manufacture by selecting springs (40) having different widths, thicknesses or other variable parameters. A modular block (38) holds the spring in the bowed condition and is positioned relative to the actuator finger by a support plate (36).  The actuator finger drives the spring against a conductive rubber block (34a,34b), compressing the block against spaced conductors (28d,28e) on a printed circuit (28) to complete the circuit.  A plurality of such switches are made in a common package by layering a printed circuit (28), insulator sheet (30), conductive rubber sheet (34) with raised bosses (34a,34b,34c), detent support plate (36) and a plurality of detent blocks (38) with bowed springs (40), between a base (26) and a cover (4).  Back lit illumination is provided by a light pipe (42) trapped against the cover as an additional layer.  A microprocessor board (52), connected to the internal printed circuit (28), is attached to the switch housing (2) exteriorly of the base (26).

Title: Method and system for monitoring the admixing of fluent materials
Inventor: CLARK WILLIAM G JR
IPC: G01N27/90
Filed: 1991-12-23
Abstract: A method and system for monitoring the admixing of first and second fluent materials that ultimately harden into a solid structure is provided wherein a selected quantity of a particulate tagging substance, whose presence is detectable by a fluctuating electromagnetic field is uniformly dispersed throughout the first fluent material. The system of the invention comprises a means for mixing together the first and second fluent materials, a conduit for conducting a flow of the resulting admixture, a tagged particle detector for detecting the concentration and distribution of the tagged particles in the mixture, and a recycling conduit and valve for recycling the admixture back to the mixing means if the admixture is in any way defective. The method comprises the steps of mixing together the first and second fluent materials, and then monitoring the distribution of the detectable particulate tagging substance throughout the admixture by transmitting the fluctuating magnetic field through it in order to determine the extent to which the materials are uniformly mixed together, as well as their relative ratios. When the admixture of fluent materials hardens into a solid structure, the uniform distribution of the particulate tagging substance throughout the structure advantageously allows it to be inspected for the presence of voids, cracks and discontinuities by the transmission of a fluctuating electromagnetic field through the structure.

Abstract: When broadcast is executed in an ATM mode, a subscriber is assigned a path and a channel as information by a central controller of a switching unit, and the information is added to a cell to be transmitted to the switching unit through a subscriber line.   The switching unit comprises the central controller, a tag information adder, and a self-routing switch.  The self-routing switch comprises a plurality of input lines and output lines, and unit switches provided for each input line corresponding to each of the output lines.  The tag information adder adds routing information for the switch to a cell to be transmitted to the self-routing switching.  The routing  information  comprises  a  set  of  bits corresponding to each output line, and the tag information adder adds to the cell the routing information in which a bit corresponding to an output line for  transmitting  the  cell  is  set  to  a predetermined logical value.   In executing the broadcast, a plurality of bits corresponding to a plurality of output lines are set to a predetermined logical value.  The self-routing switch analyzes the routing information of the cell received by each unit switch, and outputs the cell to the output line if the bit corresponding to a unit switch is set to a predetermined logical value.  If a plurality of bits of routing information are set to a predetermined value, the cell is outputted from a plurality of output lines, thus enabling the broadcast.
