Patent CA-2031569-A1 (CA)
Inventor: SNIDER PHILIP M
IPC: E21B43/25
Filed: 1990-12-05
Abstract: Method and apparatus for introducing treatment fluid into a subterranean formation by use of a reverse jet pump loca ed in a bypass of a tubing string.  A plug in the tubing between the inlet and outlet of the bypass forces production fluid to flow through the bypass.   When operation of the jet pump is terminated treatment fluid introduced into the tubing string causes a sleeve to slide down over the inlet and outlet, isolating the bypass.  The plug is then forced out the tubing, leaving a clear path for the treatment fluid down the tubing and out the casing perforations into the formation.  This arrangement enables rapid changeover from pumping formation fluid to introducing treatment fluid.

Title: Electromagnetic damping of shaft
Inventor: RICHTER EIKE
IPC: H02K7/09
Filed: 1991-01-17
Abstract: ABSTRACT OF THE DISCLOSURE    Electromagnetic damping techniques for use in slowing down the shaft of a gas turbine based on various electrical machine concepts.  A rotor may be mounted on an outer race of a bearing through which the shaft extends.  The damper may use a permanent magnet (PM) design with permanent magnets mounted to the rotor.  Alternately, the rotor and stator may be designed to operate upon a switched reluctance motor (SRM) design.  Instead of having the rotor mounted to the outer race, an alternate arrangement may use a rotor mounted directly to the gas turbine shaft in which case the rotor and a corresponding stator serve both as a damper and as an electrical generator for providing the usual electrical generation functions from the gas turbine shaft.

Filed: 1991-04-22
Abstract: A fatty acid-related polyunsaturated compound can be selectively purified using an industrially operable successive method under moderate conditions.      A highly purified fatty acid-related polyunsaturated compound is obtained by a process comprising steps of forming a complex with silver on account of the high degree of unsaturation of the fatty acid-related polyunsaturated compound, isolating the complex from other fats on account of the hydrophilicity of the complex and then applying dissociating procedures to the complex to obtain the fatty acid-related polyunsaturated compound as a target substance on account of the hydrophobicity of the fatty acid-related polyunsaturated compound. As to the procedures for dissociation, addition of a dissociating agent and reduction of silver are disclosed. As to the dissociating agent, various compounds which produce insoluble composition with silver other than water are disclosed. Furthermore, an apparatus appropriately used to carry out this method is also disclosed.
Patent CA-2041344-A1 (CA)
Inventor: PAINTER DAVID M
IPC: F17D5/02
Filed: 1991-04-26
Abstract: To detect escape or spillage of a cold liquid, for example liquefied natural gas, a narrow, robust, flexible, resilient, plastics tube, placed where the escaped or spilled cold liquid can contact it, is filled with carbon dioxide gas from a gas supply via a non-return valve and a pressure regulator which ensures that the maximum pressure in the tube  is at a desired value which is preferably greater than the pressure of the ambient atmosphere surrounding the tube.  A gas pressure drop detector  is provided to observe a pressure drop in the tube.  Should escape liquefied natural gas contact the tube the latter is so cooled that the carbon dioxide gas inside de-sublimates to a solid of greatly reduced volume causing a marked drop in pressure in the tube.  This is observed by the pressure drop detector which initiates a warning or some safety action.  A gas flow restrictor ensures that the gas supply cannot rapidly re-charge the tube before the pressure drop detector has responded to the pressure drop.

Title: Electronic capacitive level with automatic electrode selection
Inventor: HEGER CHARLES E
IPC: G01C9/20
Filed: 1990-03-20
Abstract: A capacitive type, multi-electrode inclination sensor device (20) utilizes a conductive fluid (26) acting as a common capaci-tive electrode contained within a cylindrical cavity (24). Two or more coplanar sensor electrodes (21A-21D) are covered by a thin dielectric film (22) and are mounted on an end wall (32) of the cavity (24).  Each insulated electrode (21A,-21 D) forms one plate of a capacitive element with the conductive fluid (26) forming the other plate.  The geometry of the sensor electrodes is such that for a given physical position of the device (such as level or plumb), equal conductive fluid coverage of a given pair of sensor elec-trodes occurs, yielding two identical value capacitances. Any inclination of the device within the plane of the capacitive plates then increases one capacitance's. value while decreasing the other, with the differential change in capacitance being proportional to the angle of inclination.

Title: Electric motor control apparatus and method
Inventor: DELANGE ROBERT J
IPC: H02P3/18
Filed: 1992-02-27
Abstract: An electric induction motor is connected by a switch means to a source of three-phase alternating electricity. The speed of the motor is determined by detecting when the source voltage a zero crossing and thereafter sensing the polarity of the back emf voltage induced in each winding of the motor when the switch means is non-conductive. After several zero crossings a set of polarity samples has been produced from each winding.      The motor speed is determined by detected the occurrence of a predefined relationship among samples in each set. For example, the speed is in the range of fifty to about thirty-eight percent of full synchronous speed when three consecutive samples from one winding all have the same polarity. The occurrence of the predefined relationship among back emf polarity samples can be used to control the braking of the motor.
