Patent CA-2221124-A1 (CA)
Inventor: CLERC DENIS
IPC: B05C1/08
Filed: 1997-11-12
Abstract: The method involves applying, for example, a resin product to a continuously moving steel strip (7) so it receives a coating from pick-up (4) and applicator (5) rollers. A current is generated in the liquid in front of the coating zone to drive any air bubbles to the surface so they burst. The coating apparatus consists of a bath (2) for the coating liquid (3) which is fed continuously down a sloping surface (1), while the current is created by a roller (8) which is partially immersed in the liquid and turns in the same direction as the pick-up roller and at a speed which is between 5 and 15 per cent of that of the steel strip.

Title: Video pedestal network
Inventor: LEVESQUE GILBERT
IPC: H04L12/56
Filed: 1996-05-16
Abstract: An architecture (200) for distributing digital information to subscriber units (202) wherein selection from among multiple digital services is accomplished by transmitting a tuning command from a subscriber unit to an intermediate interface (206). The intermediate interface (206) selects the desired service from a broadband network and transmits it to the subscriber unit (202) over a bandwidth-constrained access line. The bandwidth-constrained access line may be implemented with existing infrastructure, yet the subscriber unit (202) may access a wide variety of digital information available on the broadband network. Universal broadband access is thus provided at low cost. Output bandwidth of broadcast equipment may also be optimized.

Patent CA-2234094-A1 (CA)
Inventor: ARNBERG LARS
IPC: C22C21/02
Filed: 1996-10-09
Abstract: Iron is a detrimental impurity in aluminium alloys since it causes hard and brittle iron-rich intermetallic phases to precipitate during solidification. The most detrimental phase in the microstructure is the beta-phase of the Al5FeSi-type because it is platelet-shaped. The present invention provides a method of producing iron-containing Al-alloys free from platelet-shaped betaphase by controlling and regulating the precipitation path during solidification such that the precipitation of Fe containing intermetallic phases starts with the precipitation of the hexagonal phase of the Al8Fe2Sitype. The presence of the Al8Fe2Si-type phase result in that beta-phase will not develop the common platlet-morphology but nucleate on and cover the Al8Fe2Si-type phase which in turn has a less harmful morphology. Furthermore, the invention defines the use of thermal analysis as a means for controlling the morphology of the precipitates.

Title: System for multiplexed high resolution measurement of frequency variations in multimode fiber laser acoustic sensors
Inventor: FREDERICK DONALD A
IPC: G01B9/00
Filed: 1998-07-07
Abstract: A system for performing high resolution measurement of frequency variations in multimode fiber laser acoustic sensors having an end-pumped active fiber sensor emitting a plurality of lasing modes, wherein precise frequencies of the lasing modes emitted are dependent upon a strain acting on said acoustic sensor. An optical fiber is connected to the active fiber sensor for transmitting the lasing modes. The optical fiber transmits the multiple lasing modes to an optical amplifier fiber where the lasing mode signals are amplified. The amplified lasing modes signals are then fed through a phase modulator connected to the optical fiber for applying a phase generated carrier on the lasing mode signals. The output from the phase modulator is supplied to a receiving interferometer having a predetermined path imbalance for interferometrically analyzing the frequency shifts of each of the lasing mode signals, wherein the predetermined path imbalance is matched with the longitudinal mode spacing between the lasing modes of the active fiber sensor. A demodulation unit is connected to the receiving interferometer for receiving and demodulating the output of the receiving interferometer to determine the frequency shift incurred by the lasing mode signals, wherein the demodulated frequency shift is proportional to the strain acting on the acoustic sensor. In an alternative embodiment,. a plurality of active fiber sensors may be pumped by a single laser light source with their outputs multiplexed together and fed through the receiving interferometer for interferometric analysis of all the signals.

Title: Speed control system for implanted blood pumps
Inventor: BUTLER KENNETH C
IPC: A61M60/538
Filed: 1997-10-31
Abstract: An automatic speed control system continually adjusts the speed of an implanted cardiac assist blood pump to an optimum level for the varying physiological needs of the patient. It does this by periodically iteratively incrementing the speed setpoint of the pump. When the system detects the imminence of a ventricular collapse at diastole it decrements the speed setpoint by a predetermined safety margin. An alarm condition is provided if the setpoint decrease results in an insufficient blood flow rate through the pump. The flow rate and imminence of ventricular collapse are computed in real time as functions of only the pump's motor current and speed setpoint.
