Patent CA-2152445-C (CA)
Inventor: BORST RONALD WM
IPC: F16K5/04
Filed: 1995-06-22
Granted: 2004-10-12
Abstract: The float-controlled shutoff valve has an upright flow passage controlled by a transverse valve spool rotated between open and closed positions by the float in response to changing levels of liquid within the holding tank. The spool has a deep, generally U-shaped, diametrically extending cavity on one side and a single, solid sidewall on the opposite side, the cavity being so formed that it presents a cross-flow inlet approximately one quarter turn away from the passage blocking surface of the sidewall. Hence, when the spool is in its open position during filling, the cavity is vertically flow-aligned with the passage while the blocking sidewall is disposed alongside the passage, and when the spool is in its closed position the blocking sidewall spans the passage above the horizontally disposed cavity to prevent fluid movement past the spool. As the spool leaves its open position and commences progressive rotation toward its closed position, the large void area of the cavity and its lack of sidewall structure in opposition to the blocking sidewall avoids the presentation of a deflecting or impinging surface against which the flow can bear as it moves through the spool, thus avoiding the creation of a countervailing force tending to reopen the valve. Special geometric relationships between the valve body and the spool, as well as a special manner of journaling the spool for rotation relative to the body, minimize leakage past the spool itself and at the journal points, while also promoting rapid filling.

Abstract: A device for separating the yolk and albumen of an egg is provided.  A housing includes an inner chamber and an outer chamber. A lid member is detachably coupled to an upper edge of the housing.  The lid includes an annular member positioned above the inner chamber and a plurality of slots disposed adjacent to the annular member communicating with the outer chamber. The annular member is sized for retaining the yolk and for causing the albumen to overflow the annular member  with the slots allowing the albumen to flow downwardly into the outer chamber. A lever is pivotally coupled to the annular member. The lever has a bottom portion abutting a bottom edge of the annular member for enabling dispensing of whole yolk retained in the annular member into the inner chamber without breaking the yolk. A funnel is detachably mounted on the lid. The funnel has a bottom opening positioned above the annular member for directing the egg to the annular member.  A circumferential flange on a top edge of the funnel provides an anvil for breaking the shell of the egg prior to dispensing the egg in the funnel member.  The housing may optionally be provided with a closeable spout communicating with the outer chamber.  The spout provides facile removal of albumen retained in the outer chamber.

Title: Apparatus and methods for multianalyte homogeneous fluoroimmunoassays
Inventor: HERRON JAMES N
IPC: G01N33/533
Filed: 1994-05-18
Granted: 2008-02-05
Abstract: Methods and apparatus for evanescent light fluoroim-munoassays are disclosed. The apparatus employs a planar waveguide (124) with an integral semi-cylindrical lens (501), and has multi-analyte features and calibration features, along with improved evanescent field intensity. A  preferred embodiment of the biosensor (120) and assay method have patches (662) of capture molecules (720) each specific for a different analyte (210), disposed adjacent within a single reservoir (660). The capture molecules (720) are immobilized to the patches (662) on the waveguide surface by site-specific coupling of thiol groups on the capture molecules (720) to photo-affinity crosslinkers (706), which in turn are coupled to the waveguide surface (700) or to a non-specific-binding-resistant coating (702) on the surface (700). The patches (662, 664, 666) of different antibodies are produced by selectively irradiating a portion (714) of the waveguide surface (700) during the process of coupling the photo-affinity crosslinkers (706), the selective irradiation involving a mask (712), a laser light source, or the like.

Filed: 1996-03-01
Granted: 2001-07-17
Abstract: The H2S-containing gas is passed through at least one bed of a catalyst rich in metal oxide and subsequently through a final cleaning bed. On the catalyst rich in metal oxide and in the final cleaning bed elementary sulfur is deposit-ed, which is removed by a regeneration treatment carried out periodically. The final cleaning bed constitutes a fil-ter bed for the adsorption of elementary sulfur and con-sists of a granular adsorbent, which is different from the catalyst rich in metal oxide. A gas coming from the cata-lyst rich in metal oxide is supplied to the filter bed at temperatures in the range from 20 to 180C, which gas con-tains at least 250 mg elementary sulfur per Nm3 gas. From the filter bed a desulfurized gas is withdrawn, whose con-tent of elementary sulfur is not more than 30 % of the con-tent of elementary sulfur when entering the filter bed.

The modules can also operate for weeks or months at a time without being refueled and in remote locations which are subject to severe adverse weather conditions. The operations control center processes information relating to the dispensing of fuel and authorizes the dispensing of fuel at the modules upon receipt of payment information therefrom by generating and transmitting approval information to the modules. A fuel module preferably includes a transportable and multi-compartment housing, an above-ground multi-section fuel tank in the housing and a dispenser for dispensing fuel from the fuel tank upon receipt of payment information from a customer. Motion detectors are also provided to generate a motion-detect signal upon detection of motion external to the module housing, which can indicate the arrival of a customer. A diesel generator and bank of rechargeable batteries are also provided for supplying electrical energy to the dispenser in response to the motion-detect signal. The generator enables each module to function without being connected to commercial power lines from a utility.

Abstract: This invention relates to rapid set, medium set, and slow set anionic emulsions prepared from straight bitumen or bitumen modified by the incorporation of polymers such as  styrene  butadiene  rubbers   (SBR),   styrene  block copolymers (SBS), ethylene vinyl acetate copolymers (EVA), and other suitable modifiers.  The invention also relates to emulsions modified by the incorporation of solvents (such as diesel oil or kerosene) or by the addition of polymer  latices  (such  as  SBR-latex  or  natural  rubber latex).    More  particularly,  the  invention  relates  to improved methods for enhancing adhesion between asphalt and aggregate in anionic solventless and solvent-containing bituminous emulsions wherein the emulsifiers are alkali earth salts of tall oil fatty acids, fortified tall oil fatty acids, tall oil rosin and fortified rosin as well as combinations of kraft lignin and nonionic emulsifiers.  The novel adhesion enhancers utilized in these improved methods are the condensation reaction products of polyalkylene polyamines with a blend of polymerized linoleic acids and styrene  (.alpha.-methyl  styrene)-acrylic  (metacrylic)  acid copolymers.

Abstract: On the Internet, different caches may contain copies of objects that have been copied from originating servers when they were accessed by users. Interconnected caches may have different objects stored thereon that might at some time be requested by a client terminal that is connected to a cache other than the one on which the object is stored. Rather than awaiting a request for a particular object and then querying each neighbor cache to determine whether a copy of the requested object is stored thereon, and then downloading the requested object if it is found, information about the contents of the neighbor caches is exchanged between these caches so that when a request for an object is received, the object can be retrieved from the cache in which it is stored. In the alternative, the object may be retrieved from the originating server if, for example, the object stored in a cache is stale based on the date and time it was last modified in the cache.
