Title: Zirlo material composition and fabrication processing
Inventor: FOSTER JOHN P
IPC: G21C3/07
Filed: 1991-09-09
Granted: 2001-02-20
Abstract: This invention is for the processing of a somewhat broader range of compositions, including ZIRLO material. It controls creep rate in an alloy having, by weight percent, 0.5-2.0 niobium, 0.7-1.5 tin, 0.07-0.28 of at least one of iron, nickel and chromium and up to 220 ppm carbon, and the balance essentially zirconium. The method is of a type which utilizes subjecting the material to a post extrusion anneal, a series of intermediate area reductions and intermediate recrystallization anneals, with one of the intermediate recrystallization anneals possibly being a late stage beta-quench, a final pass area reduction, and a final stress relief anneal. The creep rate is controlled to about the desired amount per hour by the use of an average intermediate recrystallization annealing temperature and a final pass area reduction combination selected from the designated area of a designated figure, with the figure being selected based on whether the post extrusion anneal was an alpha or a beta anneal; on whether the final anneal was a stress relief anneal or a recrystallization anneal, and whether or not a late stage beta-quench was utilized, and the desired creep rate range. The method may also comprise subjecting the material to an alpha post extrusion anneal and a final stress relief anneal, and controlling the creep rate by the use of certain intermediate recrystallization annealing temperatures and final pass true area reductions.

Title: Crimped continuous filament yarn with color-point heather appearance
Inventor: COONS ANDREW M
IPC: D02J1/08
Filed: 1991-09-20
Granted: 1998-08-11
Abstract: A process for making a heather-dyeable or precolored heather yarn product comprises supplying a first crimped continuous filament yarn in the form of a loose matrix substantially free of filament entanglement and a second crimped continuous filament yarn which is differentially dyeable or precolored with respect to the first yarn.  The second yarn is fed through a first entangling or interlacing zone and exposure of the second yarn to a fluid jet in the first entangling zone is randomly controlled to produce a color-point yarn product as the second yarn exits the first entangling zone, in which the color-point yarn product has relatively compact nodal regions of high entanglement of the filaments of the second yarn separated by bulkier regions of the same filaments relatively free of entanglement.  The first yarn and the color-point yarn product are then fed through a second entangling zone which randomly entangles filaments of the yarns from yarn to yarn  and in which yarn-to-yarn filament commingling is substantially prevented within the nodal regions of the color-point yarn.  An apparatus for performing the process includes a randomly controllable fluid valve supplying fluid to the fluid jet in one embodiment, and a randomly controllable yarn guide to move the yarn into and out of the fluid jet in another embodiment.

Title: Injection molding nozzle insert
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/26
Filed: 1992-07-27
Granted: 2000-01-18
Abstract: A seating and sealing insert for mounting a heated injection molding nozzle in a well in a mold. The hollow insert has a cylindrical central portion extending between a rear seating portion and a forward sealing portion. The rear seating portion is outwardly flanged to seat in the well in the mold and forms an inner seat to receive a cylindrical support flange of the nozzle to accurately support the nozzle in the well in the mold. The forward sealing portion has a V - shaped forward face and inner and outer surfaces which are forced outwardly by melt pressure to seal against the nozzle and the mold. Thus, the seating and sealing insert provides an insulative air space between the heated nozzle and the surrounding mold and the forward sealing portion prevents the escape of pressurized melt into the insulative air space.

Abstract: A communications processor serves a group of several workstations with audio and video transmission processing for the purpose of providing video conferencing. The communication processor utilizes artificial intelligence software to read the connection. Conversion rules contained in tables so that the system can react to the communications environment. The system is coupled for processing optical signals for low cost communication and video conferencing with audio and video communications within the facility area and for long haul transmission. The communication processor provides audio and video communications under instantaneous constraints of the transmission medium and instantaneous degree of loading or usage. Bandwidth, resolution and transmission rate are adjustable to fit the constraints at the time a request for service is made. A workstation initiates a request for service. A request for service includes data about the nature or type of service and signal destination. This information is sufficient for the communication processor to make several attempts to threads before an affirmative determination can be made. If an affirmative determination is not possible, then the communication processor will determine which is possible and provide an output to the user for possible changes in a request.

Abstract: A reheat steam temperature control system that utilizes the separate components of a reheater and a reheat heat exchanger to generate hot reheat steam.  The reheater uses the fluidized bed as its source of heat while the reheat heat exchanger uses main steam as its source of heat.  A bypass control valve is operated to divert the required amount of main steam to the reheat heat exchanger  depending  on  operating  conditions.    Should  the temperature of the hot reheat steam be too low, additional main steam is delivered to the reheat heat exchanger.   Conversely, should the temperature of the hot reheat steam be too high, the amount of main steam delivered to the reheat heat exchanger is reduced.   Attemperators  are  used  within  both  the  reheating circuit and the main steam circuit to temper the fluctuations of their respective steam.

Abstract: A wellhead isolation tool is disclosed that is unique because the tool has no direct connection between the high pressure valve and the mandrel.   Well stimulation fluids are pumped through one or more high pressure bores which communicate with a mandrel injection head that directs the fluids into the mandrel. The injection head and the mandrel are enclosed in a sealed bore and reciprocatably movable with a piston which is used to stroke the mandrel into and out of a wellhead and to lock the mandrel in an operating position wherein ports in the injection head are aligned with the high pressure bores. The piston may be reciprocated using a mechanical screw.      A concentric mandrel embodiment providing a pack-off nipple expander is also disclosed. The tool provides superior safety features and ease of operation.

Forcible engagement between the connector mechanism and fastener produces circumferential contraction of the collar along the slot and radially against the outer surface of the conduit.

Abstract: The present invention is directed to adsorptive separation of nitrogen with active adsorbent phases with high N2 capacity and high heats of adsorption when diluted with inert material at levels ranging from 5% to 80%. The presence of diluent reduces the temperature swings in the adsorbent bed, which increases the utilizable effective N2 working capacity and decreases the relative amount of O2 left unrecovered on the active adsorbent phase. The net result is equal or better process performance allowing utilization of a lower amount of active adsorbent phase. Use of a diluent having a higher heat capacity than that of the active adsorbent phase increases these benefits, but dilution effects are beneficial even for diluents with heat capacities equal to or lower than that of the active adsorbent phase.
