Patent CA-2201660-A1 (CA)
Title: Sod roll forming machine
Inventor: VISSERS TONY
IPC: A01B45/04
Filed: 1997-04-03
Abstract: The machine serves to form an elongated strip of sod into a roll. Two conveyor belts form the lower wall and end wall of a carriage. At the side of the carriage there are spaced side walls. A strip of sod is deposited on the forward end of the belt and is conveyed to the rear where it contacts and is carried upwardly by the second belt. During this time the sod is in contact with the side walls and is confined within the carriage. The two belts cause the sod to wrap itself around a tube to form a roll. When the roll reaches the desired size the sod at the end of the roll is cut. The two belts are then tilted to the rear so that the roll of sod thus formed discharges from the carriage.

Patent CA-2216037-A1 (CA)
Inventor: WALKER CHARLES W E
IPC: G01N22/04
Filed: 1997-09-17
Abstract: A portable microwave measurement instrument is disclosed for measuring an unknown property of a test material, such as moisture content, by generating and transmitting two microwave beams of different frequency through such material so that a portion of the beam energy is absorbed by the moisture or other property. The test material is provided in test containers of different sizes and an electrical sensor is employed to sense the size of the selected container and to produce a sensor output signal corresponding thereto.  The corresponding attenuated received signals are compared in order to compensate for the presence of a component in the test material, which is not being measured but which also absorbs microwave beam energy.  A temperature compensation circuit using two thermistors is connected to the PIN diode attenuators to adjust their attenuation characteristics in compensation for changes in temperature.  To determine the density of the test material in the event of changes in such density, one of the microwave signals is used to measure the phase shift of the corresponding received signal and produce a phase shift output signal.  Temperature compensation including another thermistor is also use to maintain the frequency of such one source substantially constant by changing the source voltage.  Microwave signal connectors are employed in the measurement circuit to isolate the outer conductors of interconnected microwave signal waveguides, such as coaxial cable connectors, from DC voltage coupling and low modulation frequency coupling in 10 to 20 kHz range but to allow low impedance AC voltage coupling of the outer conductors at microwave frequencies.  The two attenuated received signals of different frequency and the phase shift output signal are combined in a signal processor to produce a percent moisture content signal.

Title: Coextruded balloon and method of making same
Inventor: BURGMEIER ROBERT E
IPC: A61F2/958
Filed: 1998-02-26
Abstract: An expander member 12 for a balloon catheter 10 to be used in stent delivery applications comprises a double-walled tubular member that is adapted for attachment to a distal  end portion of  an elongated,  flexible,  tubular catheter  body.    The  outer  wall  30  is  preferably  a polyamide, such as Nylon-12, and the inner wall 28 is PET. By properly controlling the percentage of the polyamide relative to the PET content, the distension characteristics of the resulting expander member can be tailored to fall in a range less than 15 percent.  The outer Nylon-12 layer 30 provides  the  expander  member  12  with  high abrasion resistance.   By appropriately temperature annealing the expander member, any tendency toward winging upon deflation thereof is reduced.

Title: Combustion burner and combustion apparatus provided with said burner
Inventor: KIYAMA KENJI
IPC: F23D1/00
Filed: 1997-04-30
Abstract: A combustion burner includes a mixture nozzle, a gas supply nozzle, and guide means. The mixture nozzle extends toward an interior of a furnace, and defines a mixture passage through which a mixture containing powdered solid fuel and gas for transferring the solid fuel flows.      A distal end portion of the mixture nozzle is flared so that a flow passage area of the mixture passage increases progressively in a direction of flow of the mixture. The gas supply nozzle radially surrounds the mixture nozzle to define between the gas supply nozzle and the mixture nozzle a gas passage through which a combustion oxygen-containing gas flows toward the furnace. The guide means is provided within the mixture nozzle at a position upstream of the flared portion of the mixture nozzle with respect to a flow of the mixture so as to make the mixture flow straightly along an inner peripheral surface of the flared portion of the mixture nozzle.

Patent CA-2241994-A1 (CA)
Title: System and method for efficient remote disk i/o
Inventor: VISWANATHAN SRINIVASAN
IPC: G06F13/28
Filed: 1998-06-29
Abstract: When a client computer requests data from a disk or similar device at a server computer, the client exports the memory associated with an allocated read buffer by generating and storing one or more incoming MMU (IMMU) entries that map the readbuffer to an assigned global address range. The remote data read request, along with the assigned global address range is communicated to the server node. At the server, the request is serviced by performing a memory import operation, in which one or more outgoing MMU (OMMU) entries are generated and stored for mapping the global address range specified in the read request to a corresponding range of local physical addresses. The mapped local physical addresses in the server are not locations in the server's memory. The server then performs a DMA operation for directly transferring the data specified in the request message from the disk to the mapped local physical addresses. The DMA operation transmits the specified data to the server's network interface, at which the mapped local physical addresses to which the data is transferred are converted into the corresponding global addresses. The specified data with the corresponding global addresses are then transmitted to the client node. The client converts the global addresses in the received specified data into the local physical addresses corresponding to the allocated receive buffer, and stores the received specified data in the allocated receive buffer.
