Patent CA-2075220-A1 (CA)
Inventor: ROBBINS ADAM
IPC: B01D63/10
Filed: 1992-08-03
Abstract: Cartridges for use in ultrafiltration or reverse osmosis separation devices are formed by injection molding a generally tubular, smooth, seamless shell about a spirally-wrapped semipermeable membrane assembly. These cartridges can be used within traditional separation devices having pressure vessels of precise interior diameter, for which the cartridges are uniquely suited because they have cylindrical surfaces of true circular cross-section and close tolerances. The cartridges can also be created so as to incorporate integral pressure vessels and thus permit their use in separation processes without the need for surrounding supporting pressure vessels. A reaction injection molding process is shown which provides for substantial efficiencies in the overall manufacturing of semipermeable membrane separation cartridges of the spirally-wound variety. <IMAGE>

Title: Methods and apparatus for isotopic analysis
Inventor: MURNICK DANIEL E
IPC: G01N21/39
Filed: 1993-01-26
Abstract: The isotopic composition of a multiatomic isotope-bearing species such as CO2 in an analyte is measured by maintaining the analyte in a condition such that isotope-bearing species are present in an excited state and directing light at wavelengths corresponding to transition energies of isotope-bearing species with different isotopes. The interaction between the analyte and light at the different wavelengths is monitored, as by monitoring the optogalvanic effect caused by the light of the different wavelengths. The light may be supplied by a laser (10) including the isotope-bearing species. A stable isotope such as <1><3>C or <1><8>O can be used as a tracer in a chemical or biological test and detected using the composition-determining method. <IMAGE>

Title: Fiber material of increased soluble dietary fiber and process for producing
Inventor: GREV ANN H
IPC: A23L1/308
Filed: 1993-08-12
Abstract: The present invention relates to a modified fiber material, preferably a legume or cereal grain fiber and most preferably a soy fiber material, which is characterized by an increased level of soluble dietary fiber and improved physical characteristics. The modified fiber is produced by a process which comprises forming a slurry of a fiber material, typically a soy fiber such as the spent flake residue derived from soy isolate processing, which typically has a relatively low percentage of soluble dietary fiber. The pH of the slurry is adjusted below about 4.5 by the addition of an edible acid. The pH adjusted slurry is then heated at a temperature and for a period of time sufficient to increase the soluble dietary fiber content, usually to a level of about 30% or greater of the total dietary fiber content in the case of soy fiber. Following modification, the modified fiber is dewatered to provide a food ingredient that has improved textural properties as an additive to beverages, soups, creams, emulsified meats or other types of food products.

Title: Wavelength-flattened 2x2 splitter for single-mode optical waveguides
Inventor: GONTHIER FRANCOIS
IPC: G02B6/28
Filed: 1992-04-02
Abstract: The optical waveguide coupler device (1) is formed on two laterally adjacent optical fibers (4, 5) for splitting with wavelength-flattened ratios an incident light intensity (6) into the two fibers. Adjacent sections of the two fibers (4, 5) are fused together and first and second concatenated tapered portions are formed. These two tapered portions are separated by a central optical waveguide portion (10) including two parallel branches of slightly different lengths, each capable of propagating a light signal from either tapered portion to the other. The first and second tapered portions define optical waveguide couplers (2, 3) presenting coupling ratios varying with optical wavelength in accordance with different curves. The different lengths of the two parallel branches of the central portion (10) cause a shift ~ between the phases of the optical signals propagating through these two branches. The coupling ratios of the tapered portions and the phase shift ~ are selected to wavelength-flatten the coupling ratios of the coupler device (1).
