Patent CA-2099946-A1 (CA)

IPC: H04B10/291

Abstract: We have discovered that silica-based optical fibers (e.g., 33) that are doped with Ge, Al and a rare earth (e.g., Er) can be very susceptible to hydrogen-induced attenuation change. For instance, such fiber can exhibit loss increase rates that are, at 20°C, 106 times larger than those of a standard single mode fiber. We also believe that transition metal-doped silica-based fibers can exhibit large hydrogen-induced attenuation change. In many circumstances- (e.g., amplifier fiber, attenuator fiber) significant attenuation change of optical fiber is undesirable. We disclose that such change can be substantially eliminated by provision of hydrogen gettering material and/or a "hermetic" fiber coating. It is currently preferred to provide silica cladding material that is a hydrogen getter, and also provide a "hermetic" fiber coating. Containment of the fiber, together with a quantity of a gettering material (e.g., ErFe2) in an essentially hermetic enclosure is also disclosed.

Title: Conservation of orthophosphate waste
Inventor: BENDER FREDRIC G
IPC: A23K1/175
Filed: 1993-09-13
Abstract: ABSTRACT Phosphate is recovered from waste.  Trialkali metal orthophosphate used to reduce, remove or retard bacterial contamination during raw meat slaughter including poultry, fish and shellfish and red meat evisceration is recovered from an aqueous waste and recycled as a food additive for animal feed.  The waste water containing the phosphate can be collected and mixed with offal during processing of the offal or may be concentrated and blended with the offal as feed for animals or may be reacted with an alkaline earth metal salt and concentrated and used as a calcium and phosphate supplement for animal feed.  Trisodium orthophosphate is reacted with calcium chloride and the resulting precipitate removed from the aqueous stream by filtration or centrifugation or other means for separation.  The precipitate is then added to offal during processing for animal feed or dried sterilized and sold as an animal feed mineral supplement.

Title: Process for gas phase delignifying wood pulp
Inventor: MENDIRATTA SUDHIR K
IPC: C01B11/02
Filed: 1992-07-24
Abstract: A process for delignifying wood pulp characterized by admixing an aqueous solution of chloric acid, containing about 30 percent or greater by weight of HClO3, with a non-oxidizable inorganic acid to produce chlorine dioxide gas containing less than 10 percent by volume of chlorine. The wood pulp, having a consistency of 15 percent or greater, is contacted with the chlorine dioxide gas to delignify the wood pulp. The novel process of the present invention reduces the formation of chloroform and significantly reduces the amounts of toxic by-products such as dioxin and other organic chlorides. These undesirable by-products, collectively identified as absorbable organic halides (AOX), require effluents from pulp bleaching processes to undergo expensive treatment methods to eliminate AOX's prior to discharges to sewers. The effluent discharge from the bleaching process of the present invention has less than 2.0 kg adsorbed organic halides (AOX) per ton of wood pulp.

Abstract: A method and apparatus for electronically performing bookkeeping upon a plurality of accounting journal entries having at least one account number and at least one data component associated with each account number.  A chart of accounts having account numbers and opening balances associated with the plurality of journal entries is read electronically.  A set of account-section numbers is then created for each account number.          The journal entries are electronically read and one of the account-section numbers is assigned to each account number.  The assigned account-section numbers and associated data components are then sorted in a predetermined order.  A design for the predetermined order is identified and compared with stored design records to see if such a design already exists.  If not, the new design is stored.  If so, the associated data components are added to the accumulated total for each account-section number.     A tally representing the number of account-section numbers is increased by one and an entry number is added to a list for the particular design record.  The process is then repeated for each journal entry.

Abstract: The Law of Conservation Energy is here shown to have an exception by rules that govern Weight Balance The apparatus is PRIMAL; a balance induced, Horizontal Movement of a cylinder position over a tube of fluid. The objective is to " vertically " compress the tube of fluid and force the contained fluid forward.,where it may be utilized as a transferred force of the weight. The compressing wight of contact does not require a greater height, but a circular pivot parallel motion around an axle. The cylinder is less an object of the horizontal movement. Rather it is the point of the weight contact, on the bottom circumference of the cylinder rim that is true Providence of the motion. This is a New Law of Natural Balance. The pivot-rotation on a horizontal surface and the balance induce motion are new concepts!
