Title: Optical fiber amplifying device and method therefor
Inventor: SHIBUYA TAKASHI
IPC: G02F1/35
Filed: 1996-12-13
Abstract: First and second independent optical fiber amplifiers, which preferably include first and second rare-earth doped optical fibers, respectively, are provided in a two-stage series or parallel configuration.      An optical divider for dividing and taking out pumping light to a side opposite where the pumping light is combined, is coupled to the first optical fiber. An optical combiner combines the divided pumping light with the second optical fiber from a side opposite to a pumping light source. The amplification efficiency is promoted by using the pumping light which has not been used in the one optical fiber amplifier by inputting it to the other, and vice versa. Preferably, wavelength filters block naturally emitting light to first and second optical combining and dividing instruments. Alternatively, wavelength filters block signal light in inputting the divided pumping light to the optical fiber amplifier on the other side.

Title: Free-flowing borehole servicing preparations containing linear alpha-olefins, more particularly corresponding drilling fluids
Inventor: MUELLER HEINZ
IPC: C09K8/34
Filed: 1995-06-06
Abstract: The invention relates to the use of at least predom-inantly linear hydrocarbon compounds olefinically un-saturated in the alpha-position with flashpoints of at least about 80°C as the oil phase or as part of the oil phase of oil- or water-based free-flowing borehole servicing preparations. It also relates to a drilling fluid composition comprising an auxillary fluid compris-ing such linear hydrocarbon compounds olefinically unsaturated in the alpha-position and to processes for sinking a bore in a rock. Particular significance is attributed to corresponding drilling fluids which, together with the alpha-olefins, contain other oil phases from the field of borehole servicing preparations and are distinguished by ecological compatibility, being degrad-able under both aerobic and anaerobic conditions.  Suitable mixture components for the oil phase are, in particular, oleophilic alcohols, ethers and corresponding esters selected from carboxylic acid esters and/or carbonic acid esters.

Patent CA-2206111-A1 (CA)
Title: Safe brake cutout detection for train
Inventor: MAZUR RICHARD J
IPC: B61L15/00
Filed: 1997-05-26
Abstract: A system detects cut-out of brakes on a train in a safe manner.          Each vehicle in the train has at least one truck.  Each truck has brakes which may be cut-out via a cut-out cock.  A frequency generator generates a signal at a predesignated frequency.  This signal is conveyed from a first vehicle in the train to a last vehicle in the train along a feed line and from the last vehicle to the first vehicle along a return line.  Each cut-out cock assumes an open position wherein the brakes of its truck are cut-in or a closed position wherein the brakes of its truck are cut-out.  Each cut-out cock features a switch in series with the return line that closes when its cutout cock assumes the open position or opens when its cutout cock assumes the closed position.   A frequency divider for each switch connects in parallel therewith.   When the switch is closed, the signal passes through the switch wherein division of frequency is avoided.  When the switch is open, the signal passes through the frequency divider wherein division of frequency by a preset value occurs.  A detector determines the resulting frequency of the signal returned to the first vehicle on the return line because the signal as it conducted along the return line had its frequency divided   each time it passed through one of the frequency dividers.  This enables the system to determine the number of trucks whose brakes are cut-out on the train.
Patent CA-2208767-A1 (CA)
Inventor: HUMPHREYS REGINALD D
IPC: C10G1/04
Filed: 1997-06-26
Abstract: A hot water extraction process for extracting bitumen from tar sands is taught wherein the tar sand is conditioned using an alkali metal bicarbonate, an alkali metal carbonate and a liquid hydrocarbon. A source of calcium and/or magnesium ions can also be added. The conditioning step replaces the step of conditioning usingcaustic soda previously used in tar sand extraction. The use of the alkali metalbicarbonate and carbonate and a liquid hydrocarbon substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning solution to be recycled to the process by use of a recycle storage tank.

Abstract: Flavorful baked products, such as bread, bagels, pastry, cakes, cereal, cookies, biscuits, savory crackers and snack products, are prepared using a liquid ferment typically containing a mixture of microbes that produce lactic acid and acetic acid, such as a mixture of Lactobacillus and Gluconobacter species that grow in concert when incubated at about 25° to 37°C with flour and water to achieve a ferment that has a pH of about 3.6 to 3.9, a titratable acidity of about 0.04 to 0.3 meq/g, a lactic and concentration of from about 0.5 to 2%, an acetic acid concentration of from about 0.1 to 1%, and a viscosity of less than about 100 cps. The liquid ferment is maintained in an active state such that fermented flavor can be continuously generated by adding water and flour and drawing of liquid such thatthe average residency time is from 12 to 48 hours. Saccharomyces chevalieri is used as part of the microbial complement in preferred embodiments. When used formaking bagels, concentrations of about 3 to 10% of this ferment added to the dough yield bagels that have a chewy texture and good flavor without a retarding step.

Filed: 1998-03-16
Abstract: This invention will enable the use of all the power generated by an economical, non regulated power source. It allows the power to be stored as heat for use as required. The power can be produced on a small scale, and from an erratic source. The power does not need to be produced when the heat demand is called for, and is a key feature in that the power generation source can be of a smaller scale than demand, and takes full advantage of the power production source (winds, water, etc.) when it is available. No complicated or expensive control or conditioning systems are required. This invention will allow full utilization of this power for generating high quality heat for use as hot water, building heating, or any other application where hot water is required.
