Title: Gaseous ultrasound contrast media and method for selecting gases for use as ultrasound contrast media
Inventor: QUAY STEVEN C
IPC: A61B8/00
Filed: 1992-09-02
Granted: 2006-07-13
Abstract: Disclosed herein are agents for enhancing the contrast in an ultrasound image. These agents are extremely small bubbles, or "microbubbles," comprised of specially selected gases. The microbubbles described herein exhibit long life spans in solution and may be produced at a size small enough to traverse the lungs, thus enabling improved ultrasound imaging of the cardiovascular system and other vital organs. Also disclosed herein is a method for selecting gases from which contrast agents may be produced. The method is based on calculations using inherent physical properties of gases and describes a means to associate the properties of a gas with the time for dissolution of microbubbles comprised of the gas.
Patent CA-2003475-C (CA)
Inventor: COTHERMAN ROBERT DANIEL
IPC: E21B43/12
Filed: 1989-11-21
Granted: 2001-01-16
Abstract: A submersible pump system and method for producing oil from gassy wells is disclosed in which at least first- and second-stage gas separators protect a submersible pump from vapor lock. The pump communicates with the production tubing and is driven by a shaft extending from a motor, through the first- and second-stage gas separators. The first-stage gas separator has a first-stage inlet through the housing in communication with the production fluid from the producing formation. A primary means for separating gas components from the production fluid is in communication with the first-stage inlet and expels separated gas into the annulus through a first-stage gas outlet and advances the liquid component of the production fluid through the first-stage liquid outlet. The second-stage gas separator has a second-stage inlet communicating with the first-stage liquid outlet and leading to a secondary means for separating the gas from the production fluid. The separated gaseous components are expelled through the housing and into the annulus at a second-stage gas outlet while the retained liquid components of the production fluid are presented to the pump, or to additional separation stages, through a second-stage outlet. The production fluid ultimately entering the pump inlet is substantially limited to the liquid components of the production fluid which is pumped through a pump outlet and up the production tubing.

Abstract: Circuit, and methods of using the same, are disclosed for controlling the power supplied to a discharge lamp of the type having a closed inductive loop, such as the resonant ballast circuit for a fluorescent lamp or the inductive ballast loop of a high pressure sodium lamp, wherein the closed inductive loop is operated by an electrical power supply having a d-c input stage and an output power controlled by the switching frequency of a switch means within the power supply itself whereby current flows to the closed inductive loop when the switch means is conductive and no current flows from the power supply to the closed loop when the switch means is non-conductive.  This power control circuit comprises means for sensing the instantaneous current flowing through the switch means itself, means controlled by this instantaneous current for creating a first signal with a value that is proportional to the actual power being supplied by the power supply to the closed loop, means for creating a second signal with a value proportional to the desired set point power for the lamp, means for creating an error signal having a value indicative of the difference between the first and second signals, and means for adjusting the switching frequency of the switch means in accordance with the value of the error signal, whereby the output power of the power supply is continuously adjusted toward the set point power for controlling the power actually supplied to the lamp circuit irrespective of the parameters of the lamp circuit itself.   The disclosed circuits provide for constant power to a high pressure discharge lamp to yield a constant color temperature.  Further, the disclosed circuits provide for dimming of the discharge lamp to selective power levels.

Granted: 2001-12-11
Abstract: A heat-conductive stream pipe has an upstream side and a downstream side temperature-sensing element having resistance wires wound round the pipe at a certain distance there-between to assure that there will be no thermal affection with each other. A control means controls a bridge circuit including an earthen point at one end and a connecting point at the other end of each of the temperature-sensing elements so as to keep the temperature difference between the upstream side and the downstream side temperature-sensing elements at a constant level. An auxiliary heater adjustable in its temperature is placed on the stream pipe at the downstream side near the downstream side temperature-sensing element A mass flow of the fluid is determined by the voltage measured at the connecting point of the downstream side temperature-sensing element.

Title: Fail-safe photoelectric detector
Inventor: DAHNERT DEAN L
IPC: F16P3/14
Filed: 1991-07-31
Granted: 1999-10-19
Abstract: A control circuit for continually testing a photoelectric: detector. The detector includes a light source, and a photoelectric receiver having a predetermined drop-out tuna, attached to a movable storage carriage, spaced apart and substantially sight-aligned.       The carriage has a reversible electric motor which is controlled by the control circuit, including at least two relays, the contacts of which are connected in series so that the contacts of both must be closed in order for the motor to be energized. The relay drop-cut time is substantially longer than the receiver drop-out time. In the circuit, an inverter is connected between the second coil and the light source. This inverter inverts signals received from the second coil and passes thorn to the light source so that receipt of a signal at the receiver causes the light source to turn off, in turn causing a loss of signal at the receiver, resulting in the light source turning on. An oscillation is thus established which passes through each component of the monitoring circuit and the detector. The drop-out time of the relays is long enough that the relays stay closed unless the oscillation is stopped, either by a failure of the monitoring circuit or light source or receiver, or by the light beam being broken. In either case, one or both of the relays opens, disabling the carriage from moving.

Title: Colour-matching of coatings
Inventor: MCMINN KENNETH R
IPC: B05D7/24
Filed: 1991-09-25
Granted: 2003-01-07
Abstract: A process for the sequential coating of an object with at least one undercoat and then at least one pigmented topcoat is disclosed. The undercoat is formed by admixing at least two compositions to form the undercoat, the compositions having different reflectance values and having a colour selected from white, grey and black. The admixing is controlled so that the undercoat composition has a reflectance value of ~10, preferably ~5, units of the reflectance value of the topcoat. The process reduces the number of coatings or the amount of film build of topcoat in order to achieve efficient colour match of topcoat. The process is particularly useful in the automotive industry, especially the refinish portion of that industry.

Inventor: FRUTH ANTON
IPC: C07C209/48
Filed: 1991-12-13
Granted: 2002-04-09
Abstract: Process for the preparation of saturated primary fatty amines by hydrogenation of unsaturated fatty acid nitriles According to the new process, the hydrogenation of unsaturated fatty acid nitriles or mixtures of unsatu-rated and saturated fatty acid nitriles is carried out in the liquid phase in the presence of nickel catalysts or cobalt catalysts. In a first reaction step the fatty acid nitrile, in the presence of ammonia, is treated with hydrogenation hydrogen until all the nitrile groups are hydrogenated to predominantly primary amino groups. After the ammonia content in the reaction mixture obtained from the first step has been adjusted to a value of at most 0.1 mol of ammonia per mole of fatty acid nitrile used, a second reaction step is used to hydrogenate the double bonds present to saturated bonds. The desired primary and saturated fatty amine is obtained in a very high yield and has an iodine number of at most 5.
