Abstract: ABSTRACT An assay device for determining the presence of analyte (e.g. antigens and/or haptens) in a liquid sample comprising a fiest (reagent) zone containing reference antigens and labeled Fab fragment which are capable of reacting immunologically with said analyte and said reference antigens, said Fab fragments being positioned in said first zone such that they will be removed therefrom when reacted with analyte passing through said first zone but will not be removed from said first zone in the absence of analyte; and a second (reaction) zone wherein the reaction product of said labeled Fab fragment-analyte passes after removal from said first zone and in which said label or a reaction product thereof emits a detectable signal.  The detectable signal emitted in said second zone may, for example, be a color produced by reaction with a chromogenic material in said second zone or it may, for example, be electromagnetic radiation, e.g. chemiluminescence or fluorescence pro-duced by interaction with a reagent in said second zone.

Abstract: Abstract of the Invention Bayer process liquors derived from the digestion of bauxites with a caustic solution are purified by removing at least a portion of the organic impurities present in the liquors.  Removal of these impurities is accomplished by treating liquor containing dispersed therein solids generated by the Bayer process or added thereto, such as red mud particles, alumina trihydrate, oxalate salt, or filter aid with an organic polymeric, water-soluble cationic quaternary ammonium salt (POLYQUAT salt) which due to its cationic nature will adhere to the surface of the dispersed solids.  The organic coating or layer adhered to the solids provides a receptive surface for  the organic impurities, thus allowing formation of a solid-Polyquat-organic Adduct which is easily removed from the Bayer system.

Abstract: An optical fiber telecommunication device comprises an interconnecting volume and N stations connected to this volume by pairs of transmit and receive optical fibers. Each station comprises a tunable optical frequency laser coupled to the transmit fiber and a heterodyne receiver system coupled to the receive fiber. It is provided with a tunable frequency laser local oscillator. The volume is disposed in a central office comprising a clock to determine different timing periods assigned to the N stations. The carrier frequency of the laser for each station is initially adjusted to a first frequency reserved for modulating ringing signals in the respective channels. The central office comprises a processor connected to the interconnecting volume to receive the ringing signals and designate a carrier frequency for each call request. This frequency is transmitted through the interconnecting volume to the calling station and the called station on a second reserved frequency. This is in order to adjust the frequency of the laser and the frequency of the local oscillator to the designated frequency. The designated frequencies are different for all calls in progress at the same time.

Abstract: ABSTRACT         Producing a radius or curved edge in cutting glass by means of a high pressure abrasive fluid jet.   Abrasive particles are aspirated in carefully controlled amounts into a fluid stream which is directed through a nozzle tube having an elongated passageway of small diameter, and the fluid is discharged against and closely adjacent the surface of the glass as a highly collimated jet carrying the abrasive particles.   The passageway gradually increases in diameter, or flares outwardly, at the discharge end of the nozzle tube, allowing the collimated stream to diverge within confined limits immediately prior to impinging upon the glass surface.  The abrasive particle-containing conical fluid jet cuts through the glass along the path followed by the axis of the nozzle tube, while the glass to either side of the cut is abraded by progressively decreasing amounts toward the lateral extremities of the fluid jet.  The glass cut is thus formed with a curved edge on the entrant side of the cut.   The glass may be similarly treated from the opposite direction by the abrasive jet to produce a completely rounded edge.
