  • Publication number: 20100307665
    Abstract: An RF inductor such as a Tesla antenna splices nanotube ends together to form a nanostructure in a polymer foam matrix. High Internal Phase Emulsion (HIPE) is gently sheared and stretched in a reactor comprising opposed coaxial counter-rotating impellers, which parallel-align polymer chains and also carbon nanotubes mixed with the oil phase. Stretching and forced convection prevent the auto-acceleration effect. Batch and continuous processes are disclosed. In the batch process, a fractal radial array of coherent vortices in the HIPE is preserved when the HIPE polymerizes, and helical nanostructures around these vortices are spliced by microhammering into longer helices. A disk radial filter produced by the batch process has improved radial flux from edge to center due to its area-preserving radial vascular network. In the continuous process, strips of HIPE are pulled from the periphery of the reactor continuously and post-treated by an RF inductor to produce cured conductive foam.

    Abstract: In positioning or aligning ends of optical fibers in relation to each other an offset distance between the fiber ends, the offset distance e.g. being the distance between predetermined reference positions in the fiber ends, is stepwise adjusted using a cascade technique. The method can be executed accurately and fast and be used e.g. in a procedure for core alignment, the predetermined reference positions then being the positions of the cores of the fiber ends such as the positions of the center lines or axes of the cores. Also, the method can be used in a procedure in which the self-focusing effect of optical fibers is used for finding the reference positions, which in this case are the positions of the center lines or axes of the total fiber ends, i.e. center lines or axes of the surfaces of the claddings of the optical fiber ends. Finally, the method can be used for the longitudinal positioning of the fiber ends in which the gap between end surfaces of the fiber ends is set to a desired value.

    Abstract: Method and apparatus for trimming plastic frames. Frames are joined to bring heated, soften ends into engagement, causing some softened material to be forced out from between the engaged portions, forming a flashing. This flashing is trimmed by a pair of trimming blades moved along associated guide members. The trimming assembly is mounted directly upon clamps holding the frame members, enabling performance of the trimming operation and eliminating the need for moving to a separate trimming/finishing station remote from the joining equipment. Excellent cutting action is assured by locking the guide blocks preparatory to a trimming operation. Various combinations and sequences of repetitive trimming operations may be selected whereby the cooperating blades are moved in selective cooperating directions to provide a trimming operation which avoids the need for further finishing. Trimming may also be performed simultaneously on multiple stacks of members being joined using the above technique.

  • Patent number: 6793750
    Abstract: A hand held device for joining monofilament lines together. Then device has a set of clamping jaws that can be manipulated so as to firmly position the monofilament lines in an abutting relationship in physical contact to each other. The device includes a source of electrical power and a heater, such as resistance, RF energy or ultrasonic energy, to heat the monofilament lines to a temperature exceeding the melting temperature of the monofilament lines so as to weld the monofilament lines together. A sleeve may be slipped over the monofilament lines and welded to the lines to form a more stable junction.

  • Publication number: 20040134592
    Abstract: A conduction welding apparatus and method for bonding abutted thermal plastic tubular end portions is particularly suitable for welding PFA. In a preferred embodiment, a folding weld head embraces the abutted the tubular end portions to be welded, each tubular end portion including a flange spaced from the surfaces to be joined. The weld head includes means for securing the flanges within the weld head and further include bias means. The bias means provide an inward axial bias on the adjoined tubular end portions when the tubular end portions are displaced axially outward from the weld head due to the expansion of the plastic during the weld process. The bias means in a preferred embodiment is substantially inoperative prior to the weld and provides bias, or a substantial increase in bias, when the flanges are displaced due to the expansion of the molten PFA during the weld process.

  • Patent number: 6705372
    Abstract: A buckle pivotally arranged in a movable clamp 12 of a first tube holder 1 is attached with play to a buckle 120 pivotally arranged in a movable clamp 82 of a second tube holder 2. When tubes are held in the first and second tube holders 1 and 2, release of the tubes from the holders 1 and 2 is prevented by a movement of a plunger 203 in correspondence of excitation and demagnetization of a solenoid 202 for a predetermined period of operation of the apparatus after holding the tubes (i.e., for a period required from the locking of the buckle 120 until the completion of moving-down of a wafer holder).

  • Patent number: 6685786
    Abstract: An apparatus and method are provided to improve a cutting reliability, to facilitate automation of the connection of wires and to allow for a reliable detection of wire joints. Ends of wires (a, a′) to be connected along their longitudinal directions are linearly placed, and a tape (t) is wound over and around the both wire ends. An adhesive layer of the tape is faced up, and the tape (t) is wound as the wire ends are rolled, thereby connecting the wires (a, a′). Since the tape displays a strong tear resistance in its longitudinal direction, the wires are strongly connected. The tape may contain reinforced fibers to display a stronger tear resistance. The wires (a, a′) are rolled by being held between plates (11, 33) and moving the plate (33) with respect to the plate (11). The tape (t) is placed on an auxiliary base plate (12) and is wound by the rolling movement of the wires (a, a′). The plate (33) is moved back after winding of the tape (t) to untwist the wires (a, a′).

  • Patent number: 6677880
    Abstract: There is provided a chopper type voltage comparator for comparing a sampled input voltage with a ramp voltage that is changed with a time, in which a bias voltage is changed according to the ramp voltage, and then the bias voltage comes up to a predetermined voltage value that is able to bring the chopper type voltage comparator into a comparing operation state when the ramp voltage becomes substantially equal to the input voltage. Accordingly, a voltage comparator whose consumption power can be suppressed rather than the prior art and an analog/digital-converter using the same can be provided.

  • Patent number: 6656318
    Abstract: The invention concerns a method of joining two reinforced thermoplastic material tubes having the same diameter. Ends of the two tubes are first butt welded along a peripheral weld. After forming the weld, a reinforced thermoplastic material outer jacket is fitted over most of the length of the peripheral weld, extending on either side of the weld over end sections of the two tubes. The outer jacket is heated and pressed radially until the outer jacket and the end sections of the two tubes interpenetrate.

    Abstract: A spectrum inverter receives optical values from a scanning device and applies a spectrum inversion method to the optical values. The spectrum inversion method is selected based on a medium identifier that identifies the medium upon which the scanned image is formed. The resulting spectral space values are then output and may be used by an image output device to reproduce the scanned image.
