Title: Rope for the taking along and transferring of paper webs in the manufacture of paper and cardboard on paper machines
Inventor: KAST MARTIN
IPC: D07B1/02
Filed: 1997-05-20
Abstract: A rope for the transferring and transporting of paper webs in the manufacture on paper machines of paper and cardboard made from round-braided textile fibre material. In the rope, raised portions are distributed over the circumference of the rope at regular or irregular distances. The raised portions are generated when the rope is made by the selection of a different multiple thread counts in the different running directions and/or the use of twisted and laid fibre elements, and/or by the use of fibres with profiled fibre cross-sections and/or textured or crimped fibre yarns and or by the use of fibres with profiled fibre cross-sections and/or textured or crimped fibre yarns. The rope shows improved paper grip without any other significant loss in mechanical properties.

Patent CA-2221470-A1 (CA)
Inventor: ROUILLARD CAROL A
IPC: C11D11/00
Filed: 1997-11-19
Abstract: Mold removal from plastic bottles such as polyester and polycarbonate bottles is significantly enhanced by adding to a typical caustic soaking solution an effective amount of a complex polyphosphate such as sodium tripolyphosphate and a surfactant. The combination of the phosphate and the surfactant significantly enhances mold removal. Mold removal can be further enhanced by combining with the phosphate and surfactant either a phosphonate and/or a chelating agent such as sodium glucoheptonate. This combination signficantly improves mold removal, but does not increase stress cracking of the plastic bottle.

Title: Opposed current power converter
Inventor: STANLEY GERALD R
IPC: H02M3/158
Filed: 1996-08-27
Abstract: A power converter includes a pair of switches, each of the switches being connected between positive and negative constant DC voltage sources and a common output node which is connected to a load. A modulator opens and closes the switches in a sequence in which the electrical currents controlled by the switches are in opposition to one another at the common output node, and are summed at the output node. The modulator includes a triangle wave generator and comparators which are connected to an error amplifier to provide a bearing switching voltage to the comparators. The comparators switch the control switches in response to the triangle wave generated by the tiangle wave generator increasing above and decreasing below the reference levels. Underlap and overlap of the converter is controlled by varying of the DC bias level of the triangle wave.

Patent CA-2240830-A1 (CA)
Inventor: HEYDEN WILLIAM H VANDER
IPC: G01N25/22
Filed: 1997-10-08
Abstract: The heating value of a sample gas is calculated by a microcontroller (12) from the heating value of a reference gas, and from an oxidation energy ratio determined as the gas is combusted by a flameless combustion process. The combustible gas is mixed with a combustion supporting gas, such as air, in a volume chamber (4) and injected into a combustion device (8, 50) in which a body of inert material (26, 51, 53) is heated above the auto-ignition temperature of the gas mixture. The inert material (26, 51, 53) is arranged to have a void dimension that is small enough to prevent the formation of an open flame during combustion. The process is repeated with a sample gas. During the injection cycle, the microcontroller (12) receives signals which monitor the power of combustion. The microcontroller (12) calculates the heating value of the sample gas and generates an output signal to a visual display or other output device.

Title: System and method for transparent, global access to physical devices on a computer cluster
Inventor: KHALIDI YOUSEF
IPC: G06F9/445
Filed: 1998-06-29
Abstract: A system and method are disclosed that provides transparent, global access to devices on a computer cluster. The present system generates unique device type (dev_t) values for all devices and corresponding links between a global file system and the dev_t values. The file system is modified to take advantage of this framework so that, when a user requests that a particular device, identified by its logical name, be opened, an operating system kernel queries the file system to determine that device's dev_t value and then queries the a device configuration system (DCS) for the location (node) and identification (local address) of a device with that dev_t value. Once it has received the device's location and identification, the kernel issues an open request to the host node for the device identified by the DCS. File system components executing on the host node, which include a special file system (SpecFS), handle the open request by returning to the kernel a handle to a special file object that is associated with the desired device. The kernel then returns to the requesting user a file descriptor that is mapped to the handle, through which the user can access the device.

Abstract: Cellulosic webs can be embossed using an extended nip structure with embossing means in a controlled nip dwell zone.  Single and multiply wipes and towels produced by plying together two or more such webs can be embossed.
