Title: Natural gas liquefaction
Inventor: WILKINSON JOHN D
IPC: F25J3/00
Filed: 2004-04-26
Abstract: A process for liquefying natural gas in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane is disclosed. In the process, the natural gas stream to be liquefied is partially cooled, expanded to an intermediate pressure, and supplied to a distillation column. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas. The residual gas stream from the distillation column is compressed to a higher intermediate pressure, cooled under pressure to condense it, and then expanded to low pressure to form the liquefied natural gas stream. ® KIPO & WIPO 2007

Title: Photochromic material comprising a proteorhodopsin apoprotein and retinal analog
Inventor: JENSEN RASMUS B
IPC: A61K31/07
Filed: 2005-06-09
Abstract: The present invention relates to a photochromic material comprising a proteorhodopsin apoprotein and a retinal analog. In one embodiment, the retinal analog is an azulenic retinoid compound. In another embodiment, the retinal analog is a compound that is structurally similarly to all-trans-retinal. The proteorhodopsin apoprotein and the retinal analog form a photochromic material having different spectral properties from those of a corresponding photochromic material formed by the same proteorhodopsin apoprotein and all-trans-retinal. In one embodiment of the application, the retinal analog-containing proteorhodopsin has an absorbance spectrum that does not overlap significantly with that of all-trans-retinal-containing proteorhodopsin. In another embodiment of the application, the retinal analog-containing proteorhodopsin yields a red-shifted visual chromophore compared with the all-trans-retinal-containing proteorhodopsin chromophore. The photochromic material of the present invention is useful as an optical data storage carrier, a fraud-proof optical data carrier, security ink, and in other optical applications.

Title: Method for allocating sequence and method for setting circular shift sequence against frequency offset
Inventor: KWON YEONG HYEON

Filed: 2007-02-05
Abstract: A method for allocating a sequence and a method for setting a circular shift sequence over a frequency offset are provided to increase a detection error or a false alarm rate due to a frequency offset by allocating a sequence without a circular shift applied thereto to a cell having a frequency offset greater than a certain level. Cell information in which a frequency offset is higher than a certain level is obtained.

In setting the cyclic shift application interval, the reception sequence and a channel response position of the aliases are checked, and a cyclic shift application available interval is set such that the reception sequence and the channel response position of the aliases do not overlap by a shift due to one or more of a return delay and a channel delay spread.
