  • Patent number: 5651794
    Abstract: Dyed cellulosic regenerated elongate members such as fibers are produced by dyeing the regenerated members with a cationic direct dye after formation but before first drying. A method of producing the dyed elongate members comprises forming a dope containing cellulose or a cellulose compound in solution in a solvent, extruding the dope through at least one orifice into a bath containing water to form an elongate extrudate from which solvent is dissolved and/or the cellulose compound is converted to cellulose so as to form the elongate member, dyeing the formed but never dried elongate member with a cationic direct dye and optionally also with an anionic direct dye and then drying for the first time the dyed elongate member.

  • Patent number: 5503262
    Abstract: For the classification of a pattern in particular on a banknote or a coin, a receiving system detects, by a measurement procedure, vectors of a test item, a pre-processing system transforms the measured vectors into local feature vectors ALCi(l) and a learning classification system carries out a plurality of testing operations. A first activity compares in a first testing operation each of the local feature vectors ALCi(l) to a vectorial reference value. It is only if the first testing operation takes place successfully that the first activity, by means of first estimates which are stored in a data base, links the local feature vectors ALC(l) to provided global line feature vectors AGIi.

  • Patent number: 5498879
    Abstract: An apparatus for the optical recognition of documents (1) extends over the entire width of a transfer plane (3). Regularly disposed photoelectric elements (4), whose optical axes Create a single sensor plane (5) that is perpendicular to transfer plane (3), receive light (7) as altered by document (1). Photoelectric elements (4) are regularly disposed in a manner in which their optical axes are contained in a sensor plane (5) perpendicular to transfer plane (3). A region (8) of document (1), determined by sensor plane (5), is illuminated by at least one light line (9 or 10) which is inclined with respect to sensor plane 5. The light modified by document (1) is received by photoelectric elements (4). The adjacent light sources in each light line (9,10) are separated by a uniform source distance (A), which is smaller than the sensor distance (B) between two adjacent photoelectric elements (4). The light sources emit light within a narrow spectral width in pulses of short duration.

  • Patent number: 5485264
    Abstract: An OTDR stores data samples in a predetermined sequence in a memory. Data is read from and written to the memory in the predetermined sequence by application of successive control signals. The stored data is read, added to a correlated sample of a new signal and the result stored to maintain the predetermined sequence of samples. Successive tests thus accumulate samples in sequence to provide an indication of the variation of the signal as the light pulse passes along the fiber under tests.

  • Patent number: 5484508
    Abstract: A method of making feedstock from material supplied in rolls of flexible sheet material which comprises the steps of creating a pluri-layer web of "n" different layers of sheet material, each layer being selected with regard to some known parameter property of the sheet material whereby the pluri-layer web has an aggregate value of the selected parameter which lies within a chosen range of values of said parameter property. Conveniently the feedstock is created by disintegrating the pluri-layer web to create a mass of comminuted pieces of sheet material.

  • Patent number: 5475610
    Abstract: An instrument for performing highly accurate PCR employing a sample block in microtiter tray format. The sample block has local balance and local symmetry. A three zone film heater controlled by a computer and ramp cooling solenoid valves also controlled by the computer for gating coolant flow through the block controls the block temperature. Constant bias cooling is used for small changes. Sample temperature is calculated instead of measured. A platen deforms plastic caps to apply a minimum acceptable threshold force for seating the tubes and thermally isolates them. A cover isolates the block. The control software includes diagnostics. An install program tests and characterizes the instrument. A new user interface is used. Disposable, multipiece plastic microtiter trays to give individual freedom to sample tubes are taught.

  • Patent number: 5471058
    Abstract: The invention provides an anesthesia monitor being able to directly make a separation and a determination in real time all components of a gas in which components having the same integer molecular weight exists, more particularly an expiration gas and an inspiration gas as the object of analysis. The monitor has a small size, a low price and a operational facility. A microscopic quantity of the expiration gas is introduced from a circular route of an anesthesia circuit for an inhalation anesthesia to the anesthesia monitor through a material pipe-line. A gas portion is transmitted by a rotary pump through valves and opening and closing valves to a measurement cell within a vacuum chamber arranged in a gap of between magnetic poles of permanent magnets in a Fourier transformation mass analyzer so that the expiration gas is subjected to a high speed sampling. An ionization of the ions is carried out within the measurement cell.

  • Patent number: 5469109
    Abstract: Improved apparatus and methods for programming anti-fuse devices utilized in programmable semiconductor chips are described. An anti-fuse device circuit is disclosed wherein an anti-fuse device is connected between two programming transistors, and each programming transistor is connected to a separate voltage supply bus and to a control bus network having, for example, a common control bus or separate control buses. Interconnection structures of anti-fuse devices can be formed and a targeted anti-fuse device can be programmed by connecting a programming voltage to the first associated supply bus, by connecting another voltage or ground potential to the second associated supply bus, and by turning on the appropriate control bus line or lines so that the programming transistors conduct to provide a voltage differential across the targeted anti-fuse device.
