Patent CA-2389284-A1 (CA)
Inventor: UNDERWOOD RANDALL B
IPC: C02F1/52
Filed: 2000-10-27
Abstract: A method and apparatus for processing waste streams wherein a slipstream is formed on the upstream side of an ultrafiltration membrane (120) to carry collected and concentrated filter reject to a microfilter (170) via a conduit (155) at low flux through the microfilter (170). The low flux allows the particles to form an irregular matrix that itself helps to trap particles. The effluent from this matrix and microfilter (170) is returned upstream of the ultrafiltration membrane (120) to be repeatedly collected and concentrated. The suspended solids removed from the reject stream and microfilter (170) are then disposed of without further processing. To improve metal ion removal efficiency, sulfide compounds, etc.  can be injected upstream of ultrafiltration membrane (120). A combination of ozone and water can be used to backflush or to clean the ultrafiltration membrane (120). The backflushing water can be filtrate from the ultrafiltration membrane (120).

Patent CA-2391981-A1 (CA)
Title: Interferometric microwave sensor
Inventor: JEAN BUFORD RANDALL
IPC: G01N22/00
Filed: 2000-11-20
Abstract: A novel microwave sensor (10, 60, 70, 90, 200, 250, 280) provides low-cost, robust measurement of the electrical properties of fluid substances. The sensor is suitable for use in an industrial vessel or pipe and employs parallel electrical transmission paths (12, 14) that differ in electrical or physical length. The electrical length of each transmission path, which may be a two-way path caused by placing a reflective element in each path, is further determined by the electrical properties of the material under test. The frequency (f) of the signal being applied to the sensor is varied in a known manner such that the difference in the electrical lengths (.DELTA.L) of the transmission paths (12, 14) is caused to correspond to an odd integral multiple of a half wavelength. When the frequency is so adjusted and the signals that have traversed the transmission paths are allowed to coherently interfere with one another, then a minimum resultant signal or null is obtained. The null frequency for which a minimum signal is obtained is a direct measurement of the real part of the electrical permittivity (.epsilon.r) of the material under test and thus provides a measurement from which material composition can be inferred. The material under test may be stationary of flowing past the probe element without affecting the characteristic of the measurement. An important application of the measurement method is that of determining the quality of steam and a preferred embodiment of such a sensor is described. Other fluid substances can be sensed using the sensor by the present inventions.

Title: An improved structure of a flexible water tap
Inventor: OUYOUNG SCOTT
IPC: F16K27/04
Filed: 2002-07-16
Abstract: This invention relates to an improved structure of flexible water tap with a nozzle having an extension pipe that can be pulled out from the water outgoing pipe to facilitate the rinsing and water supply, wherein the middle of the outgoing water section of the inner nozzle has an axial pipe and a plurality of passages transversally disposed in the middle section of the inner nozzle, so that the water passing through nozzle can be split into two flowing paths. Different elements are installed at the two water outgoing positions on the end cover in order to give different ways for the outgoing water. Further, a splitter set is installed by passing through the middle section of the nozzle. The operation of the splitter set produces a transversal displacement such that the entire structure only requires one hand to pull the nozzle from the position of the water outlet of the water tap, changes the flow path as well as the outgoing water condition, and thus attains the effect of convenient rinsing with simple control.

Patent CA-2403209-A1 (CA)
Inventor: SERGEEV PAVEL V
IPC: A61K31/52
Filed: 1999-04-08
Abstract: This invention relates to a new method of synthesis of biologically active substances of determined structure directly in the cells of living organisms containing specific RNA or DNA molecules of determined sequence. The method is based on the hybridization of two or more oligomers bound with biologically inactive precursors of biologically active substances to specific RNA or DNA  in vivo in the cells of living organisms. After hybridization of the oligomers to RNA or DNA the biologically inactive precursors bound to the 5' and/or 3' ends of the oligomers can interact with each other to make biologically active form of the substances. This changing of properties is due to chemical reactions which bind the biologically inactive precursors through a chemical bond into a biologically active form of the whole compound.

Filed: 2002-10-29
Abstract: A keyboard for computers and data entry devices is disclosed, which increases typing speed, but at the same time eases the transition from the Standard Qwerty keyboard for experienced typists. Two letter sequences called digraphs are typed rapidly when struck by opposite hands. The proposed keyboard places frequently used digraphs on opposite hands and avoids the use of small fingers to increase typing speed. The home row is not emphasized and only three high frequency keys are moved relative to Qwerty positions, making the keyboard easy to learn. The constraints of maximal speed and minimal modification are satisfied concurrently. A second key is dedicated to the letter "E", the most frequently used letter in the English language, to further enhance typing speed and ease of transition from Qwerty.         The result is a faster and highly practical electronic keyboard.
