According to the invention the still liquid or partially vaporized methane-rich fraction (5?) is fed to a circulation vessel (D), only the liquid fraction of the methane-rich fraction (5?) occurring in the circulation vessel (D) is completely vaporized, preferably in natural circulation, and the top product (7) of the circulation vessel (D) is superheated (E1).Type: ApplicationFiled: November 3, 2009Publication date: September 1, 2011Applicant: Linde AktiengesellschaftInventors: Heinz Bauer, Rainer Sapper, Martin Gwinner, Georg Schopfer

Publication number: 20110209500Abstract: A jewelry system for expressing a user's emotional state. The jewelry system includes a rotatable wheel and a stationary member having an aperture. The rotatable wheel has a number of emotional states indicated therein on its face. The stationary member and the rotatable wheel are substantially the same size so that when the stationary member is mounted over the rotatable wheel, the stationary member and rotatable wheel are substantially aligned. The stationary member covers the emotional states except for a selected emotional state that remains visible via the aperture. The rotatable wheel is capable of being rotated to display a selected emotional state through the aperture for viewing by the general public while other emotional states that are not selected remain concealed by the stationary member. The jewelry system might also include optional detachable charms.Type: ApplicationFiled: February 26, 2010Publication date: September 1, 2011Inventor: ANITA SCOTT

Publication number: 20110209503Abstract: A method of making a fused silica article having a combined concentration of protium and deuterium in a range from about 1×1016 molecules/cm3 up to about 6×1019 molecules/cm3. In some embodiments, deuterium is present in an amount greater than its natural isotopic abundance. The method includes the steps of providing a fused silica boule, diffusing at least one of protium and deuterium into the boule, and annealing the boule to form the fused silica article. A method of diffusing hydrogen into fused silica and a fused silica article loaded with hydrogen formed by the method are also described.Type: ApplicationFiled: May 12, 2011Publication date: September 1, 2011Inventors: Michael A. Mueller, Michael Thomas Murtagh

Publication number: 20110209504Abstract: A lightweight thin flexible latex glove article having a polymeric latex coating that penetrates the front portion of a knitted liner half way or more through the liner thickness and for at least a portion of the knitted liner, not penetrating the entire thickness. For example, the liner can be knitted using an 18-gauge needle with 70 to 221 denier nylon 66 multi-filament yarn. The polymer latex coating can be 0.75 to 1.25 times the thickness of the knitted liner. Over 30% reduction of glove thickness is achieved resulting in three times greater flexibility. The polymer latex coating may be foamed with 5 to 50 vol % air content. Open celled foamed latex coating may be coated with a dispersion of fluorochemical dispersion to prevent liquid permeation into the glove. The process can include steps to gel the latex emulsion at interstices of the yarn to prevent further penetration of the emulsion into the liner.Type: ApplicationFiled: August 25, 2010Publication date: September 1, 2011Applicant: Ansell Healthcare Products LLCInventors: Eric Thompson, Dave Narasimhan, Jeffrey C. Moreland, Hafsah Mohd Ghazaly

Publication number: 20110209506Abstract: A combination locking arrangement includes a locking member, a locking lever connected to the locking member; and at least first and second tumbler discs rotatable about a tumbler disc axis. When each of the tumbler discs is rotated to an unlocking orientation, the locking lever engages aligned recesses in the tumbler discs, such that further rotation of the tumbler discs moves the locking member from the locking position to the releasing position. A dial is rotatable about the tumbler disc axis for selective rotation of the tumbler discs, and includes a drive portion rotationally secured in interlocking engagement with the first tumbler disc in one of a plurality of code selecting orientations. The locking lever includes a disc securing portion positioned to prevent axial disengagement of the first tumbler disc from the dial drive portion when the locking lever is engaged with the aligned recesses in the tumbler discs.Type: ApplicationFiled: February 28, 2011Publication date: September 1, 2011Applicant: MASTER LOCK COMPANY LLCInventors: Mark D. Johnson, Rafael Hiram Gutierrez Medina

Publication number: 20110209507Abstract: A clutch for an electronic door lock includes a first shaft, a second shaft, a spring, a rheological fluid, and a plunger. The second shaft has an aperture therein and is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The spring is disposed in the aperture in the second shaft. The rheological fluid is held within the aperture and is capable of changing viscosities in response to the application of an electrical current across the fluid. The plunger is biased by the spring into selective coupling engagement with the first shaft and is capable of selective motion into the aperture in response to contact by a camming surface of the first shaft due to relative rotation of the first shaft with respect to the second shaft.Type: ApplicationFiled: November 28, 2008Publication date: September 1, 2011Inventors: Fanping Sun, Zaffir A. Chaudhry, John M. Milton-Benoit, Ulf J. Jonsson

Publication number: 20110209508Abstract: A bicycle lock device for public use is disclosed. The device is comprised of an enclosure, a retractable reel with a retractable cable, a lock/unlock device having a first member attached to the cable free end, and a second member secured in the enclosure, and a lock control device. The user accesses the device by inserting a payment such as a coin or credit card in a user interface of the device. If the payment is accepted, the user then enters a user-specified key code in a keypad on the lock control device. The lock control device unlocks the lock/unlock device. The retractable cable may then be extended. The user weaves the cable through the bicycle components and then enters the cable free end into the lock/unlock device, thereby locking the lock/unlock device and securing the bicycle. When the user later enters the key-code, the device unlocks the cable.Type: ApplicationFiled: February 26, 2010Publication date: September 1, 2011Inventor: Jacob Silas Lee Andersen
