Title: Filter for separating photoactive agent
Inventor: PIECHOCKI DUANE
IPC: A61M1/36
Filed: 1995-06-29
Abstract: Disclosed are methods, systems and devices for processing a biological fluid. Specifically, disclosed is a method for processing a biological fluid comprising the steps of removing red blood cells from a biological fluid to produce a plasma protein-containing biological fluid that is substantially free of red blood cells, placing the plasma protein-containing biological fluid in contact with a photoactive agent, activating the photoactive agent, separating the photoactive agent from the plasma protein-containing biological fluid by passing the agent-containing fluid through a photoactive agent binding arrangement including carbon fibers, and recovering the plasma protein-containing biological fluid.
Patent CA-2153369-A1 (CA)
Title: Protection for motors in refrigerated environment
Inventor: VENETUCCI JIM M
IPC: F25D21/04
Filed: 1995-07-06
Abstract: A protection system for electric motors in refrigerated environments, especially those environments cooled to very low temperatures, includes routing a cryogen coolant through the electric motor. A minimum flow of cryogen coolant is maintained through the motor to prevent ingress of moisture in the motor interior.  The arrangement is especially useful with cryogenically cooled refrigeration systems, because the same cryogen coolant used to refrigerate the system can also be used to provide a purging flow of cryogen coolant gas through the electric motor.

Title: Electrophoretic Display with Arc Driven Individual Pixels
Inventor: DI SANTO FRANK J
IPC: G02F1/167
Filed: 1994-01-31
Abstract: An electrophoretic display (10) includes a laminated triple pane construction with an    electrophoretic fluid-containing  envelope (24) formed between the first and second panes (12, 14) and an ionizable gas-containing envelope (26) between the second and third panes (14, 16). A transparent reference electrode (20) coats the first pane internal to the fluid envelope. A matrix of discrete pixels are disposed upon the second pane (14) within the fluid envelope (24). Each pixel has a probe (30) extending therefrom through the second pane (14) and into the gas envelope (26). A plurality of row electrodes (32) are disposed upon the second pane (14) in the gas envelope (26) in close proximity to corresponding rows of probes (30). A plurality of column electrodes (28) disposed upon the third pane (16) within the gas envelope (26) perpendicular to the row lines (32) establishing an addressable X-Y matrix.  By impressing a sufficient voltage differential at selected intersections of the matrix, a local ionization of gas biases a proximate probe to the ionization potential. The probe potential is shared by the corresponding pixel, setting up an electrostatic field relative to the reference electrode (20) for controlling the movement of pigment within the fluid.

Title: Uniform compaction of asphalt concrete
Inventor: HOLLON EDMUND D
IPC: E01C19/26
Filed: 1994-05-06
Abstract: Apparatus is described for obtaining uniform compaction of asphalt concrete to reduce or prevent cracking of the asphalt concrete surface. A mobile confinement edge force is maintained in contact with the edge surface of an asphalt concrete mat while the mat is being compacted.  This is performed in a manner such that the density of the mat across the full width of the mat becomes uniform. By obtaining uniform density of each lane of the mat as it is laid significantly, reduces the incidence of joint cracking and deterioration of the asphalt concrete, in the longitudinal joint area, over time.

Filed: 1996-03-14
Abstract: Method and apparatus are disclosed for deinterlacing of an interlaced video frame sequence using interpolation estimations, such as spatial and temporal interpolations. Interpolations requiring a less accurate estimation of missing pixel values in the frames being deinterlaced, such that an interpolation may be performed with a minimum of error, are performed before interpolations which require a more accurate estimation of missing pixel values for performing an interpolation, such that estimates of missing pixel values are obtained with a minimum of error.

Patent CA-2172116-A1 (CA)
Inventor: NELSON THOMAS J
IPC: B27M3/00
Filed: 1996-03-19
Abstract: Disclosed is laminate flooring and other articles with tongues and grooves for joining sections of the flooring or articles and a method of making the tongue and groove joints.  The lower surfaces of the tongues and grooves are indexing surfaces for aligning the wear surfaces of the flooring sections.  The tongues and grooves are made such that when the tongue is fully inserted into the groove, a continuous space is formed between the upper surface of the tongue and groove.  The grooved edges are cut at an acute angle to the surface.  This provides a space between the upper surfaces of the tongue and groove and between the edge surfaces above the tongues and grooves toward the wear surfaces of the flooring sections.  Glue in the joint, upon curing, resists penetration of moisture and increases the strength of the joint.

Abstract: A master/slave communication and control system includes a master controller and a plurality of slave subsystems, the master controller connected with the slave subsystems through first and second independent serial data buses, one of the data buses providing a working data bus, the other data bus providing a standby data bus. The master controller generates a A/B select signal applied to each of the slave subsystems to select which of the A or B data buses the slave .subsystems will use to communicate with the master controller. Each of those slave subsystems generates an independent request for communication signal, carried on an input request line to the master controller. A plurality of kill signals are generated by the master controller and applied over independent kill lines to each of the slave subsystems, whereby the master controller may send the kill signal to any one of the slave subsystems. Each of the slave subsystems can receive its respective kill signal and disconnect itself from the data buses.
