Title: Single facer with small intermediate corrugating roll
Inventor: MARSCHKE CARL R
IPC: B31F1/28
Filed: 1997-03-26
Abstract: The labyrinth path in the corrugating nip of a single facer is substantially reduced by utilizing a small diameter intermediate corrugating roll (12) captured between a pair of larger diameter conventional corrugating rolls (10, 11). The two large diameter rolls capture the smaller roll and prevent bending thereof under corrugating loads. The corrugator may be operated at high speeds without the adverse increase in labyrinth path and web tension characteristic of large diameter corrugating rolls.

Title: Optical waveguide, waveguide amplifier and laser
Inventor: BROCKLESBY WILLIAM SIMON
IPC: H01S3/16
Filed: 1996-08-23
Abstract: An optical fibre amplifier, laser or superluminescent source, consisting of a chalcogenide glass matrix hosting trivalent rare earth ions and which is doped with oxide in the form of a metallic oxide. The device utilizes the properties of the added oxide to improve the fabrication and efficiency of optical waveguide sources, in particular for applications around 1.3 µm. Specifically, the oxide broadens the wavelenght range for pump absorption, broadens the wavelength range for light emission, increases the device efficiency through a change in lifetime of certain laser levels and modifies properties of the glass to prevent crystallization during fibre fabrication. The device exploits the intentional addition of oxide to improve amplifier, laser, glass and fibre properties.

Patent CA-2232662-A1 (CA)
Inventor: CISNEROS DENNIS
IPC: E21B10/52
Filed: 1998-03-18
Abstract: A steel tooth bit includes one or more rolling cone cutters having a generally conical surface, a heel surface, and preferably a transition surface therebetween. A row of gage cutter elements are secured to the cone cutter on the transition surface and have cutting surfaces that cut to full gage. A first inner row of off-gage steel teeth is positioned on the conical surface of the cone cutter so that the gage-facing cutting surfaces of the teeth are close to gage, but are preferably off-gage a distance D at a knee that is formed on the gage facing surface. Distance D is strategically selected such that the gage and off-gage cutter elements cooperatively cut the corner of the borehole. The lower most portion of the gage facing surface of these steel teeth are off gage a distance D' which is greater than D so as to bring the cutting tip of the teeth off gage to prevent undesired wear and rounding off of the tip of the cutter element. The upper most portion of the gage-facing surface is also preferably off gage a distance D" that is greater than D so as to optimize the surface area on the gage facing surface that is in contact with the borehole corner.
