Title: Lyocell fibers and process for their preparation
Inventor: LUO MENGKUI
IPC: D04H3/03
Filed: 1997-08-22
Granted: 2009-09-01
Abstract: The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers. The fiber is produced by centrifugal spinning, melt blowing or its spunbonding variation. The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into selfbonded nonwoven fabrics.

Title: Simultaneous detection isotopic ratio mass spectrometer
Inventor: MERREN THOMAS OLIVER
IPC: G01N30/72
Filed: 1999-04-19
Granted: 2008-02-19
Abstract: The invention comprises a mass spectrometer 1 and a method of mass spectrometry that is especially useful for the measurement of the isotopic composition of hydrogen in the presence of a helium carrier gas. Interference to the accurate measurement of the small HD+ peak at mass-to-charge ratio 3 by the much larger He+ peak at mass-to- charge ratio 4 is reduced by provision of an energy filter 35 in the ion detector assembly used to collect HD+ ions. This prevents ions of He+ which have lost energy through scattering, etc giving rise to a signal from the HD+ detector and distorting the deuterium hydrogen isotopic ratio measurement. Such a mass spectrometer 1 is typically used in conjunction with a continuous flow inlet system 4 based on an elemental analyzer that converts hydrogen present in a sample to gaseous hydrogen in a flow of helium carrier gas. Another embodiment of the invention provides a similar mass spectrometer useful for carbon or oxygen isotopic determinations in carbon dioxide gas.
