Patent CA-2352885-A1 (CA)
Inventor: WITEK WERNER
IPC: D21H17/70
Filed: 2001-07-11
Abstract: During the chemical process of loading with calcium carbonate fibers contained in a pulp suspension, a medium containing calcium oxide or calcium hydroxide is added to the pulp suspension. This treated pulp suspension is charged in at least one reactor with pure carbon dioxide (or a medium containing carbon dioxide), which, during the progression of the reaction, converts at least a significant portion of the starting materials (calcium oxide and/or calcium hydroxide anal carbon, dioxide) into the reaction products, calcium carbonate and water. This reaction is accomplished by properly controlling the pulp suspension's pH.
Patent CA-2354771-A1 (CA)
Title: Syringe pumps
Inventor: TRIBE ROBERT JAMES
IPC: A61M5/172
Filed: 2001-08-07
Abstract: Conventional syringe pumps have a motor rotating a leadscrew to drive a plunger head actuator along it. The head actuator engages the plunger of a syringe and moves the plunger along the syringe barrel to dispense medication. In the present invention, an optical encoder mounted on the leadscrew is rotated by the motor to produce a pulse output. A control unit times the interval between the pulses and compares these timings with a stored value representative of a predetermined multiple of the minimum time. If the head actuator is obstructed, the speed of rotation of the motor is slowed and the time interval between pulses rises. When this exceeds the stored value, the control unit stops the drive to the head actuator and generates an alarm.

Patent CA-2367962-A1 (CA)
Inventor: XIA TAI-HE
IPC: G16B5/20
Filed: 2002-01-16
Abstract: Conditional associations among features in samples are identified by defining a matrix having rows that represent the samples and columns that represent the features. Each row-column position of the matrix has a first binary value if the sample that is associated with the row exhibits the feature that is associated with the column, and a second binary value if a sample that is associated with the row does not exhibit the feature that is associated with the column. Recursive partitioning then is performed for each column. In particular, for each column, the column is recursively partitioned relative to the remaining ones of the columns, to define a tree of conditional branches for the rows for each column. The collection of trees of conditional branches for the columns may be displayed and/or analyzed to identify conditional associations of interest. Continuous features, wherein each row-column position of the matrix has a value selected from a continuous range of values, also may be analyzed.
