Abstract: An improved method for separating and recovering protein and isoflavones from a plant material containing the same. A clarified protein extract of the plant material is prepared and contacted with a polar ion exchange resin, allowing the isoflavones in the extract to bind with the ion exchange resin and depleting the extract of isoflavones. A protein extract which has been depleted of isoflavones is separated from the ion exchange resin, and an isoflavone depleted protein material is recovered from the isoflavone depleted extract. After removal of the isoflavone depleted extract from the resin, the isoflavones are separated and recovered from the ion exchange resin. Recovered isoflavone glycosides and isoflavone glycoside conjugates may be converted to their corresponding aglucone isoflavone form.

Title: Glass fiber nonwoven fabric and printed wiring board
Inventor: MIURA YASUSHI
IPC: D04H1/58
Filed: 1998-12-01
Abstract: A nonwoven fabric constituted of high--flatness glass fibers whose cross sections have aspect ratios of 2.0 to 10 and rates of filling of 85 % or above, preferably 90 % or above. Such glass fibers have nearly rectangular cross sections and therefore can be arranged in an extremely dense state to give a nonwoven fabric which is extremely thin and has a high bulk density. The fabric can give laminates which are enhanced in the glass fiber content and improved in the surface smoothness, thus being suitably usable as the reinforcement for printed wiring boards. The glass fibers can be produced by the use of, e.g., a nozzle equipped with a tip which has a flat orifice and whose major-axis wall is partially cut out on one side.

Filed: 2000-12-12
Abstract: A customer data capture system integrated with a dealership data management system allows customer and vehicle maintenance data to be exchanged between a kiosk on the floor of the dealership and the data management system. The customer inserts a customized card into a kiosk, and interacts with the pre-programmed software on the kiosk. The software recommends scheduled maintenance services and suggests potential coupon savings, based on the information received from the customer's card and the information stored in the data management system. A service order is generated and routed to the service department. As a result, the accuracy and speed of entering customer data are enhanced, while the dealership is able to offer value-added services at the point of sale, thus enhancing the dealership's business relationship with the customer.
Patent CA-2330511-A1 (CA)
Inventor: WILDE WILLIAM DAVID
IPC: B28C7/00
Filed: 2000-12-29
Abstract: This application relates to an apparatus designed to collect concrete from a ready mix truck discharge chute. Separate the coarse and fine aggregate fraction from the cement slurry and return the cement slurry back into the ready mix truck drum for reuse or discharge upon return to the point of production. The apparatus consists of a portable container combining an open-ended collection hopper including removable screens and an air operated pressure vessel, The apparatus is suspended off the end of the truck discharge chute and residual concrete a washed onto the hopper and over the screens. Coarse and fine aggregate is retained on the screens and the cement slurry water passes through in to the pressure vessel below. When the pressure vessel is filled to capacity, regulated air pressure supplied via the truck air system is applied to the vessel that in turn discharges the slurry through a discharge hose back into the ready mix drum.  The apparatus has no moving parts, utilizing low-pressure regulated air for means of transfer. The apparatus allows for job-site collection and reuse of high PH cement slurries thereby preventing contamination of work sites and adjoining waterways.
Patent CA-2330724-A1 (CA)
Inventor: POPP ROGER C
IPC: F02M47/04
Filed: 2001-01-10
Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg. 300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions.  The fuel injector is powered by hydraulic signals from an electrohydraulic valve.  The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. The cartridge comprises an activator body and a valve body secured together, and the valve body has a gas valve slidable therein. The stroke of the valve is adjustable by controlling the size of shims in the valve body assembly, thereby providing a universal valve cartridge that can be easily adapted to differing fueling requirements for models and sizes of engines. The valve body includes a spring chamber between upper and lower valve guides. The valve body also includes cross-holes to allow cool gaseous fuel to successively pulsate into and out of the spring chamber and thereby cool the exposed portion of the valve between guides, preventing heating of the dynamic gas seal located in the upper guide. An unsealed small clearance between the actuating piston and its bore in the actuator body allows controlled leakage of oil. The leakage of oil lubricates metal to metal contact between the upper guide and the valve and lubricates the dynamic gas seal. Gaseous fuel leakage into the leaked oil is tolerated and any combined oil/gaseous fuel is removed to an external location for separation. Spring washers are used to urge the valve assembly insert against a metal O-ring supported by the outer cartridge body.

Inventor: GUILLEMET GUY
IPC: E05D15/44
Filed: 2001-01-04
Abstract: A mechanism for selectively operating and locking a pivotal window. The window is pivotally attached to a window frame so as to pivot between open and closed configurations. The mechanism includes an actuating rod slidably mounted to the window frame. A guiding arm is pivotally mounted to the window frame. An actuating arm is pivotally attached to the actuating rod. The distal end of the actuating arm is attached to the window by attachment component allowing for angular compensation. The distal end of the guiding arm is pivotally attached to the actuating arm intermediate the longitudinal ends of the latter. A pin and slot arrangement allows for selective pivotal or locking action between the guiding and actuating arms depending on their relative pivotal relationship. The sliding movement of the actuating rod along its longitudinal axis in one direction causes the window to open while the sliding movement of the actuating rod in the opposite direction along its longitudinal axis causes the window to close and eventually to be locked in the closed configuration.
