Abstract: The invention concerns a method for regenerating a hydrogenation catalyst, and hydrogenation methods carried out with a catalyst comprising at least one regenerated catalyst. More particularly, it concerns a method for regenerating Raney catalysts used in total or partial hydrogenating processes of compounds comprising nitrile functions into amine functions. Said method consists in treating the spent catalyst with a basic solution and optionally in subjecting said catalyst to hydrogenation before stripping to eliminate the impurities present on the catalyst. Thus, the regenerating method enables to recuperate up to 100 % of the catalytic activity.

Title: Hydrodynamic-mechanical multi-speed compound transmission, especially a six-speed torque-converter transmission
Inventor: NITSCHE MARTIN
IPC: F16H3/66
Filed: 1999-03-08
Granted: 2004-08-10
Abstract: The invention relates to a hydrodynamic-mechanical multi-speed compound transmission (i) with at least four speeds. Said transmission comprises a transmission input shaft (E) and a transmission output shaft (A) as well as a hydrodynamic transmission part (2) and a mechanical transmission part (4). The hydrodynamic and the mechanical transmission parts are connected in series when seen from the power flow direction. Means are provided for by-passing the hydrodynamic transmission part (2) during power transmission.      The hydrodynamic transmission part (2) comprises at least one hydrodynamic speed-torque converter (3). The mechanical transmission part (4) includes a mechanical speed-torque converting device (5) with at least two planetary gear sets (7, 8). The mechanical transmission part (4) is designed in such a way that transmission ratios in the individual gear steps cause gear step jumps of phi <=1.45 between two successive gear steps of the individual speeds. Various, optionally selective starting variants can be obtained by using different shifting element controls allocated to the theoretically possible speeds. Systematic gear step abandonment provides various gear variations using one gear, resulting in different final arrangements of the speeds.

Title: Endotoxin reduction in nucleic acid purification
Inventor: WHITE DOUGLAS H
IPC: C12Q1/68
Filed: 1999-04-22
Granted: 2003-08-12
Abstract: The present invention presents a novel method for removing endotoxins from nucleic acids, such as DNA, RNA, or hybrids thereof, contaminated therewith.  Nucleic acid solutions which can be treated using the method of this inventi on include, but are not limited to, lysates of gram-negative bacteria and nucle ic acid solutions contaminated with endotoxins from external sources. The prese nt method removes endotoxins from such solutions using silica-based materials, such as silica gel particles, magnetic silica particles, or diatomaceous earth. In a preferred aspect of the method of this invention, magnetic silic a particles are used to isolate plasmid DNA from a lysate of gram-negative bacteria transformed with the plasmid DNA. Application of the disclosed meth od produces nucleic acids which are sufficiently free of endotoxin contaminatio n to be useful for a variety of different practical applications. Figure 1 sho ws a plot of units of endotoxin bound vs the number of milligrams of particles added to lysates of each of two differerent strains of bacteria, JM109 (& ;loz;) or DH5.alpha.(♦).

Abstract: Attachment of a bridge (18) and temple hinge (32) to the lens (12) of eye glasses. The attachment is accomplished by providing a pair of apertures (30) of a selected configuration in each lens adjacent to the outer and inner surface of the lens, a bushing (24) conforming to the lens apertures with a tapered aperture through the center thereof from front to back end tapering the distal ends of the bridge and temple hinges. This combination when in place in the lenses apertures provides a friction lock between the lens and the bridge and temple hinge.      The taper can be in the range of 1 to 45 degrees. In another embodiment the lens can also have a tapered aperture either convergent from the front to the back of the lens or divergent from the front to the back of the lens. Ideally a taper of 4.5 degrees in the bushing is preferable with less taper in the lens apertures when tapered lens apertures are utilized. The taper can take the form of a frusto conic section, a cylinder, a rectangular or triangular in cross section. The distal ends of the bridge and temple hinge can be inserted either from the front of the lens toward the back or from the back toward the front. The distal ends of the temple hinge can be inserted directly into the aperture within the bushing for attachment or can additionally be bent formed to provide a bias between the outer surface of the lens adjacent the aperture for non rotational support. In some applications a notch is provided at the outer lens surface and the bent formed portion of the temple hinge is nested therein for additional mechanical support and to increase the resistance of relative rotation of the bridge or temple hinge.

Abstract: A method and an arrangement providing detection of deteriorated lamp filaments (3) in a lamp circuit (11) fed by constant current, in particular for a lamp supervision system for airfield lights. A change in a constant current fed through a lamp circuit (11) is initiated, whereby the lamp filament resistance is determined once in conjunction with the change in current and once a time period later. A difference between the resistance determinations constitutes the deterioration of a lamp filament (3) in comparison with a threshold value.  Hence, no record of previous resistance determinations have to be stored, and lamps (4) can be replaced when the difference matches the threshold value.

Abstract: A method for processing of seismic data traces utilizes the fact that a seri es of linear operations (40) applied to vectors (10) can be approximated by application of the linear operations to a set of basis vectors (20) which are then scaled and summed (40). The method is applied to seismic data traces (5) with a reduction in processing time provided that computation time in creating the basis vectors is small relative to the total computation time in applyin g the method. Theoretically there is much to be gained in terms of processing speed by implementation of this method on a vector processor (50) that is designed to multiply and accumulate operations quickly.

Title: Apparatus and method for measuring polarization-dependent loss using repeated high speed polarization scrambling
Inventor: LEE BONG-WAN
IPC: G01J4/00
Filed: 2002-02-07
Granted: 2009-11-17
Abstract: Disclosed is an apparatus and method for measuring a changing amount of insertion loss of an optical device depending on a polarization state of an incident light, i.e., a polarization-dependent loss. An incident light that is periodically subject to all polarization states passes through a testing optical device by a polarization scrambler including a piezoelectric element type optical fiber birefringence modulator, and an optical detector measures intensity of the passing light, in which the measured intensity values are averaged for birefringence modulation having a constant period, and then the polarization-dependent loss is computed from a ratio of maximum power to minimum power for the period. Use of the birefringence modulator shortens measuring time, and decreases an affect of external disturbance to the incident light that is incident into the testing optical component or occurrence probability of the external disturbance, so that the polarization-dependent loss can be precisely measured.
