Patent CA-2130339-A1 (CA)
Title: Antibacterial coated medical implants
IPC: A61M25/00
Filed: 1993-03-04
Abstract: An implantable medical device having long lasting resistance to staphylococcal biofilm colonization is provided. Implantible medical devices such as catheters, shunts, prosthesis, pacemakers, etc, are susceptible to colonization by biofilm adherent microorganisms, especially staphylococci. While systemic staphylococcal infections are effectively treated by many antibiotics, vancomycin being the antibiotic of choice, this same bacteria when encased in biofilm adhering to indwelling medical devices is generally resistant to antibiotic treatment. By the present invention, the combination of rifampin and minocycline or the combination or rifampin and novobiocin when coated on the surfaces of implantable medical devices unexpectedly provides superior antibacterial activity against staphylococcal biofilm colonization on the coated surface of indwelling medical devices.

Title: An Absorbent Core Having a Density Gradient
Inventor: CRAINIC SORIN
IPC: A61F13/56
Filed: 1993-07-16
Abstract: In a sanitary napkin (10), the retention layer (34) of the absorbent core is covered by a first tissue sheet of a density between 0.01 g/cm3 and 0.1 g/cm3 and by a second tissue sheet of a density between 0.08 and 0.3 g/cm3, the difference in density between the tissue sheets being between 0.01 g/cm3 and 0.2 g/cm3. The density gradient on top of the retention layer (34) results in a relatively high efficiency of the retention layer (34) and in efficient draining of the topmost tissue sheet, so that chances of rewet are reduced.

Title: Method and apparatus for sensing an input current with a bridge circuit
Inventor: COBURN DAVID C
IPC: G01R1/20
Filed: 1995-01-26
Abstract: A current sensor includes first and second branches interconnected by a center conductor magnetically coupled to an annular current comparator for producing an output signal related, in magnitude and phase, to an input current. The input current divides, according to a predetermined relationship, between the first and second branches such that the current in the center conductor interconnecting the first and second branches is also related to the input current. A current is induced in the annular current comparator in relation to the current in the center conductor and, thus, in relation to the input current.      Secondary windings are wound about and magnetically coupled to the annular current comparator for producing an output signal responsive to the current induced within the annular current comparator.
Patent CA-2141385-A1 (CA)
Inventor: HOWARD LEE JARVIS
IPC: C07B63/00
Filed: 1995-01-30
Abstract: Refrigeration is provided in an ethylene recovery plant by an open-loop mixed refrigeration cycle which utilizes components present in the ethylene-containing feed gas as the mixed refrigerant. Refrigeration is provided by subcooled mixed refrigerant at -175° to -225°F for the demethanizer overhead condenser and for initial cooling and condensation of the ethylene-containing feed gas.  Overall ethylene recoveries of up to 99.9% can be achieved at reduced power consumption compared with conventional ethylene recovery cycles. In addition, significant capital savings can be realized due to the simplification of equipment with the open-loop mixed refrigerant cycle, which can be operated advantageously at pressures between 150 and 400 psia.

Title: Digitally controlled circuit interrupter with improved automatic selection of sampling interval for 50 hz and 60 hz power systems
Inventor: JOHNSON RICHARD ARTHUR
IPC: G01R23/10
Filed: 1995-05-25
Abstract: A circuit interrupter with a digital trip unit automatically sets the sampling interval appropriate for the 50 Hz or 60 Hz distribution system to which the interrupter is connected. In order to avoid falsely shifting the interval in response to distorted currents, the trip unit only changes the interval if the number of zero crossings of the current within a fixed number of samples is within two zero crossings of the number of zero crossings for an undistorted current of the other frequency for two consecutive time periods in which the fixed number of samples are taken. Furthermore, changes in the interval are only written into an EEPROM for use on power-up a fixed number of times to preclude disabling the EEPROM. In one embodiment, a 2 pole filter is utilized in the zero crossing counting circuit to eliminate false counts from noise originating in a chopper used in the trip unit power supply. In another embodiment, the zero crossing counting circuit is disabled unless external dc power is available for the trip unit which idles the chopper.

Title: Method and a Device for Use in Coil Pipe Operations
Inventor: SOLA KJELL INGE
IPC: E21B19/22
Filed: 1995-11-24
Abstract: The invention relates to a method and a device for use in coil pipe operations.  A coil pipe (12) is coiled up on a rotary drum (10) and is fed out/in in relation to the drum (10) by means of a feeding device (14) having a rectilinear, through-going passage for the coil pipe (12).  In order to reduce the number of straightenings/bendings of the coil pipe (12) to a minimum, the drum (10) is disposed in the immediate association with the feeding device (14), said drum (10) and said feeding device (14) being positioned and orientated such in relation to each other that an imaginary extension of the feeding device's coil pipe passage (16) extends substantially tangentially to the outer circumference of the coil pipe coil on the drum (10). This measure reduces the number of straightening/bending strains to one straightening upon the coil pipe's uncoiling and one bending upon the coil pipe's (12) coiling up on the drum.  The drum (10) may be swingable about a horizontal axis (36), in order to compensate for varying coil pipe coil diameter during uncoiling/coiling, so that the tangential directional course of said passage (16) is maintained during the entire uncoiling/coiling operation.

Patent CA-2172739-A1 (CA)
Title: Singlemode optical fiber signal termination
Inventor: LEONARD PIERRE
IPC: G02B6/38
Filed: 1996-05-14
Abstract: This is a handtool which terminates the signal transmitted within singlemode optical fibers. The termination is induced by exposing singlemode optical fibers to 5 or more macrobends at a predetermined extent. The macrobends are produced by straight or U-shape pins, pre or mechanically positioned, which are perpendicular to the base plate and supported by the base plate of the handtool. The fibers are snaked manually through the pre-positioned pins or simply inserted in the U-shaped pins. The pre-positioned pins induce macrobends of a predetermined extent to the fiber/s which terminate the optical signal. Similarly, the mechanical design places the pins in position for inducing the macrobends of a predetermined extent and hence, terminating the optical signal.
