Title: Horizontal cyclone separator for a fluidized bed reactor
Inventor: GARCIA-MALLOL JUAN A
IPC: B04C1/00
Filed: 1992-10-09
Abstract: HORIZONTAL CYCLONE SEPARATOR FOR A FLUIDIZED BED REACTOR    Abstract of the Disclosure A reactor in which a furnace section, a heat recovery section and a horizontal cyclone separator are formed in a vessel.  A bed of solid particulate material including fuel is supported in the furnace section and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel.  A mixture of air, the gaseous products of combustion and the particles entrained by the air are directed to the vortex chamber of the cyclone separator through an inlet duct.  The helical end of the vortex chamber forces the mixture to spirally circulate within the chamber, where the solid particles of the mixture are separated by centrifugal forces.  A central tube extends partially within the vortex chamber and receives the cleaned gases from the low pressure center of the chamber.  The portion of the tube behind the helical end of the vortex chamber opens directly into the heat recovery area for passing the clean gases thereto.  A trough extends from the lower portion of the vortex chamber to the fuel bed for receiving the separated particles and returning them to the bed.

Patent CA-2087719-A1 (CA)
IPC: H03D3/02
Filed: 1991-08-16
Abstract: An improved frequency synthesizer (100) capable of producing true DC frequency modulation without the need to DC fre-quency modulate the reference oscillator. The synthesizer (100) includes a phase comparator (104) which compares the reference signal (102) and the feedback signal (112). The output of said phase comparator (104) is filtered and coupled to the main VCO (108). A balanced image mixer (200) mixes the two signals from the main VCO (108) and an offset VCO (300). The offset VCO (300) is a low frequency (e.g. 100 to 300 KHz) integrated offset VCO (308) whose center frequency is controlled accurately, by means of matching to a VCO (306) which is controlled by a feedback loop, and by using an image balanced mixer (200) to reduce the image response to substantially reduce or eliminate the filtering required at the mixer output. The configuration of the offset mixer within the synthesizer loop, any residual spurious content due to imperfect image balance or carrier feedthrough of the mixer is attenuated by the loop response. The output signal of the mixer (200) is looped back to the phase comparator (104) after being divided by N through a divider (114).

Title: Fluid coupling and fastener capture device
Inventor: BYNUM KURT K
IPC: F16L19/00
Filed: 1992-02-21
Abstract: A new capture device comprising a plurality of axially extending tangs (42) on one (10) of a pair of complementary fittings (10, 14) in a fluid coupling and a polygonal circumferential groove (20) on the other fitting (14) adapted to engage the fangs.  Upon rotational engagement of the fittings the tangs (42) engage the polygonal groove (20) and "ratchet" about the junctures between the flats (22) until the coupling is tight. Although not limited to particular materials, the new capture device is particularly suited to very tough, strong and hard materials such as titanium, stainless steel and Inconel alloy because the effectiveness of the capture device is dependent upon the stiffness of the tangs (42). The new device prevents vibrational disassembly of the complementary fittings without preventing disassembly solely with wrenches. Moreover, the complementary fittings and capture device can be repeatedly assembled and disassembled without any damage to the treads (12) or capture device. A variety of configurations of the capture device are illustrated and applications to a bolt and nut and a hole plug (e.g. turbine engine borescope port) are disclosed.

Title: Label trapping assay-nonseparation binding assay method
Inventor: HEPP JOZSEF
IPC: G01N33/537
Filed: 1993-09-08
Abstract: ABSTRACT A method for determining the amount of analyte in a sample.  The method comprises providing a first assay compartment and a second assay compartment.  The compartments are separated by a barrier permeable to a signal providing binding reagent-label conjugate.  An analyte containing sample is combined with a binding reagent-label conjugate capable of binding to the analyte to form alone or, in combination with a second binding reagent, a specific binding pair complex of a size sufficiently large to prevent passage through the barrier.  The binding reagent-label conjugate is provided in an excess of the amount required to bind with all the analyte.  The mixture is incubated to allow the analyte to bind to the binding reagent-label conjugate to form the specific binding pair comprising the analyte and the binding reagent-label conjugate and for unbound binding reagent-label conjugate to pass through the barrier into the second compartment.  The unbound binding reagent-label conjugate is entrapped and modified in the second compartment to enable detection of a signal from the specific binding pair as a measure of the amount of analyte bound in the specific binding pair.  The detectable signal is measured.

Abstract: A high temperature ceramic filter is produced from a com-position containing refractory cement, aggregate, pore forming additives, and sintering agents. The pore forming additives are synthetic or organic powders or fibers which sublimate, melt, or otherwise disintegrate to produce in situ pores in cement during refractory treatment of a cast filter. The filters produced are permeable to high temperature gases commonly found in a coal furnace and can be used to collect particulate matter present in those gases. The filter apparatus includes a housing having an in-let and outlets for particulate and clean gas respectively. A tube sheet divides the housing into a raw gas chamber and a clean gas chamber. Candle filters are suspended in the raw gas chamber and pulsating air flow is injected into the candle filter from a pulse air source.
