  • Publication number: 20070095062
    Abstract: A simple and robust variable coaxial capacitive sensor and detection method for monitoring the position of a rapidly reciprocating member such as a piston or displacer in a free piston Stirling engine. The coaxial capacitor of the present invention in a preferred embodiment thereof is configured to modulate capacitive electrode area rather than inter-electrode spacing and as a result a highly linear transfer function can be achieved. Also disclosed are detection methods which derive and process signals in connection with applications which have small sensor capacitance variations while suppressing stray capacitance error.

  • Publication number: 20070095070
    Abstract: Conventional auxiliary power units (APUs) may experience over-temperature shutdowns when attempting to start them at high altitudes. Further, such conventional APUs may also experience overspeed conditions when a generator load is removed during on-speed operations. A fuel control logic that controls the fuel flow cutback below the minimum blowout fuel schedule is provided. A temperature trim loop measures engine temperature to determine the onset of a possible over-temperature condition. The fuel flow may then be trimmed accordingly to correct this over-temperature onset. Further, when the onset of an overspeed condition is detected, such as when a generator load is removed, the fuel flow may be trimmed accordingly to correct this overspeed onset. The fuel control logic allows the control to find the individual minimum fuel flow for each fuel control without risking blowout of the APU itself.

  • Publication number: 20070095076
    Abstract: An apparatus, system, and method are disclosed for separating minerals from mineral feedstock—for example bitumen from tar sand. The apparatus includes residence chambers for contacting solvent and tar sand. The solvent-tar sand contact occurs in at least two stages. The drained miscella from the first stage is sent to a flashing module to separate the miscella into recovered solvent, a bitumen stream, and a volatile hydrocarbons stream. Solvent is recycled from the final stage and reused in the residence chambers. An energy recovery module recovers the energy from the volatile hydrocarbons stream. A solvent stripper removes the solvent residue from the drained tar sand to create a cleaned sand stream, and the solvent stripper recycles the solvent vapors to energize and assist the separation process. The apparatus enables a water-free, energy efficient, and nearly complete recovery of bitumen from tar sand.

A condensing line heat exchanger is connected between an inlet port and the compressor and is so disposed that the evaporator fan passes air thereover to provide cooling to the ambient air passing therethrough such that condensation forms within the tube. A water separator is included in the system to remove condensate and allow the drier air to pass to the compressor. The water separator is so constructed as to allow for the free flow of air therethrough with very little restriction. A drain fitting in the water separator is so constructed as to prevent spattering that might otherwise occur.

    Abstract: Improvements in systems and methods which employ a two-phase fluid, such as a refrigerant, as a saturable fluid in direct heat transfer relation to a thermal load, are realized by extraction of vapor from the saturated fluid before heat exchange. Moreover, automatic changing of the paths under command of a controller enables charges to be effected between different modes at higher rates than in other systems by employing the variety of modes available in the direct transfer system.

  • Publication number: 20070095099
    Abstract: In this method, the LNG stream (11) is cooled using a refrigerating fluid (83) in a first heat-exchanger (19). The refrigerating fluid (83) is subjected to a second semi-open refrigeration cycle (21) which is independent of the first cycle (15). The method comprises a step for introducing the stream (59) of sub-cooled LNG into a distillation column (49) and a step for recovering a stream (69) of gas at the top of the column (49). The second refrigeration cycle (21) comprises a step for forming a stream (73) of refrigerating fluid from a portion of the top stream (69) of gas, a step for compressing the stream of refrigerating fluid (73) to a high pressure, then a step for expanding a portion (81) of the stream (75) of compressed refrigerating fluid in order to form a substantially liquid sub-cooling stream (83). The substantially liquid stream (83) is evaporated in the first heat-exchanger (19).

  • Publication number: 20070095101
    Abstract: A jewelry forming article utilizes free magnetic bodies and free deformable chains to form various jewelry objects, such as rings, bracelets, necklaces, and the like. The various jewelry objects are formed by magnetically engaging the surfaces of the free magnetic bodies to two or more regions along a length of the deformable free chains, forming one or more loop circumferences along the length of the chains between the engaging regions, where the loop circumference may be increased or decreased by changing the positions of the engaging regions relative to the surfaces of the magnetic bodies to enable a person to secure the article on his or her body in the form of the various jewelry objects.

  • Publication number: 20070095103
    Abstract: A jewelry piece, which includes a setting of at least two pear-shaped precious stones, placed adjacent to each other resembling a heart shape. The heart shaped setting is defined within a metallic frame having a convex front and a curved back. Two top pins and a bottom pin positioned on the front of the metallic frame secure the heart shaped setting. The jewelry piece is further decorated with more jewels paved on metallic frame along the periphery of the heart shaped setting. The metallic frame could also be made with a flat front and a flat back. And a setting pin assembly could be used to secure the heart shaped setting in place. The setting pin assembly may include three strips joined at a center point and running equally outwards in three different directions.

    Abstract: The present invention has the purpose of providing optical fiber base material having an even ratio of core to clad in the longitudinal direction thereof and method of easily manufacturing the same. In the method of manufacturing the optical fiber base material using the outside vapor deposition (OVD) process, a burner is relatively reciprocated against and along an initial material and deposits glass fine particles on the initial material. In the above method, the relative reciprocation is stopped at the returning positions in a certain period, preferably, in no less than 3 seconds and no more than 60 seconds.

    Abstract: An intermediate preform is formed in a process of manufacturing an optical fibre by forming a sol containing a glass precursor; pouring the sol in a mold containing a set of elongate elements; aging the sol to obtain a gel body; removing the set of elongate elements from the gel body to create a corresponding set of holes in the gel body; and removing the gel body from the mold. The method further provides imparting a motion of the set of elongate elements during aging of the sol to avoid adhesion of the gel to the elongate elements, the motion being preferably a rotation about the respective axes or an alternate translation along the respective axes. An apparatus with means for carrying out the method is also described.

  • Publication number: 20070095108
    Abstract: Apparatus and methods are provided for reducing the variability of stress levels in glass sheets (11) cut from a moving glass ribbon (13). The reductions in variability are achieved by constraining the edge regions (53,55) of the ribbon (13) from movement in a horizontal plane at at least one location below the location where a separating assembly (20) forms a separation line (47) in the ribbon (13). Sets of vertically arranged wheels (35) which engage the edge regions (53,55) of the ribbon (13) can be used to provide the horizontal constraint without compromising the central, quality area (51) of the glass ribbon (13).
