Title: Optical fiber having low loss at 1385 nm and method for making same
Inventor: KALISH DAVID
IPC: G02B6/00
Filed: 1998-06-10
Abstract: A singlemode optical fiber [700] having very low loss at 1385 nm, and a practical method for making same are disclosed. A core rod [20] is fabricated using vapor axial deposition to have a deposited cladding/core ratio (D/d) that is less than 7.5. The core rod is dehydrated in a chlorine- or fluorine-containing atmosphere at about 1200°C to reduce the amount of OH present to less than 0.8 parts per billion by weight, and then consolidated in a helium atmosphere at about 1500°C to convert the porous soot body into a glass. The consolidated core rod is elongated using an oxygen-hydrogen torch that creates a layer of OH ions on the surface of the rod that are largely removed by plasma etching. Finally, the core rod is installed in a glass tube [40] having a suitably low OH content. Thereafter, the tube is collapsed onto the rod to create a preform [60]. Conventional methods are employed for drawing an optical fiber from the preform and applying one or more protective coatings [75, 76]. The disclosed method is suitable for commercial production of low-OH fiber. Significantly, the fiber's loss at 1385 nm is reduced to a level that is less than its loss at 1310 nm, thereby rendering the entire wavelength region 1200 - 1600 nm suitable for optical transmission. In particular, wave-division-multiplex systems are nowavailable to transmit optical signals over distances greater than 10 km in the wavelength region between 1360 nm and 1430 nm.

Title: Process for reducing fat content of pork skin and products made therefrom
Inventor: LYNCH DONALD A
IPC: A23L13/20
Filed: 1998-11-12
Abstract: A process is disclosed for the calculated removal of fat from pork skin. Pork skin is subjected to tumbling cycles during which the pork skin is tumbled first in warm water and subsequently in warm water containing salt and concentrated laundry detergent. As this two step cycle is repeated, fat contained within the pork skin separates and is drained from the pork skin with the rinse water. The cycle may be repeated until the pork skin contains a desired percentage of fat. The process does not require that the pork skin be ground or otherwise comminuted in order to selectively remove fat from the material, nor does the process use harsh solvents or chemicals that might render the pork skin inedible or toxic.      Because the process is all natural, the reduced fat whole pork skin is edible and may be formed into a variety of canine treats through additional processing and cooking. These canine treat products may include knotted bones, twisted products, chips, filled bones, sticks, patties and various ground products.
