Abstract: An extensional flow mixer especially for viscous liquids has a housing (10) with an end inlet (12a, 14a) connectable to a pressurized source of the liquids, and an outlet (119) at an opposite end of the housing (10). A mandrel (30) located in the cavity has protrusions (20', 32') with sloping side surfaces, the outer edges of which cooperate with the internal surface (114a) of the cavity to divide the cavity into a series of chambers separated by slits, such that liquid passes successively through all the chambers and slits in moving from the inlet (12a, 14a) to the outlet (119). The slits have cross-sectional areas which decrease in the liquid flow direction. The mandrel (30) sides have helical grooves (134) forming passageways with the housing wall (114a) which allow liquid to be distributed evenly around the edges of the mandrel (30) to the inlet end or upstream chamber. The mandrel (30) may rotate to provide additional shear mixing.

Patent CA-2311434-A1 (CA)
Title: Differential photoelectric receiver circuit
Inventor: HARTLEY LEE F
IPC: H03K17/785
Filed: 2000-06-13
Abstract: A photoelectric receiver circuit provides a symmetrical sensor having a transimpedance amplifier on each side of the PIN diode, the outputs of the transimpedance amplifiers being AC coupled to a differential post amplifier. The differential structure provides a very high common noise voltage rejection ratio and a virtual ground to the inverting inputs of the transimpedance amplifiers. In the preferred embodiment a differential PIN diode bias voltage is established by separate bias voltages respectively applied to the non-inverting input of each transimpedance amplifier. Thus, a low-noise voltage regulator can be used to supply power to the bias voltages in the invention, and the AC coupling capacitors can be very small to conserve space on the chip die. Auxiliary DC currents applied to both sides of the PIN diode maintain the PIN diode bias as high as possible and maximize the output swing ranges of the transimpedance amplifiers in order to retain a wide bandwidth. The DC current sources allow the output bias voltages of the transimpedance amplifiers to be adjusted, and when controlled by the transimpedance amplifier outputs through a low pass filter, the output bias offset caused by ambient light can be eliminated. The feedback resistors may be variable resistors to provide automatic gain control.

Abstract: A method is provided for forming an autologous graft by distending a donor blood vessel, and harvesting the distended portion of the vessel. Also provided is a device for in vivo, or in vitro vessel distension. Typically t he device is implanted, for example, using endoscopic techniques, in a patient sometime prior to another surgery on that patient, which includes implanting  a vascular graft. The device includes a stretching mechanism which is attached  to a donor blood vessel, means for operating the stretching mechanism to cau se the vessel to distend, and a controller, preferably externally located, for controlling the operating means. In a preferred embodiment, the device includes a pair of opposed straps (10, 12) attached to a healthy, small diameter donor blood vessel such as a femoral artery in the leg. The straps (10, 12) are displaced from each other over a period of time to continuously  distend or elongate the donor vessel. The distended portion of the donor vessel is excised at the time of the bypass surgery. The ends of the donor vessel are then sutured end to end to repair the donor vessel, a procedure common in vascular repair, and generally accomplished without complication. The result is a totally autologous, living vascular graft.

Title: Shaft breakage detection apparatus
Inventor: NOBRE ANTONIO H
IPC: F01D21/04
Filed: 1999-06-03
Abstract: The present invention is addressed to a control logic for determining the occurrence of shaft decoupling in a gas turbine engine. The control logic in the preferred embodiment receives inputs for shaft rotational speed and/or compressor pressure and uses these parameters for making a determination of shaft decoupling in fractions of a second, before serious damage to the gas turbine engine can occur. The control logic also utilizes multiple interval sampling, and sampling over multiple channels to verify any determination of shaft decoupling.  Once a shaft decouple has been verified, fuel flow to the engine is cut off, thus shutting down the engine.
