Title: Integrated process for purifying and liquefying a feed gas mixture with respect to its less strongly adsorbed component of lower volatility
Inventor: KUMAR RAVI
IPC: F25J3/02
Filed: 1994-09-29
Abstract: ABSTRACT A process is set forth for purifying and liquefying a feed gas mixture with respect to its less strongly adsorbed component of lower volatility which integrates temperature swing adsorption (TSA), pressure swing adsorption (PSA) and cryogenic distillation to optimize overall performance.  The TSA portion of the process is used to remove the strongly adsorbed component from the feed; the PSA portion of the process is used to remove the moderately strongly adsorbed component from the feed; and the cryogenic distillation portion of the process is used to remove the less strongly adsorbed component of higher volatility from the feed while also providing for the liquefaction of the product.  A key to the present invention is the use of the PSA and distillation waste streams in the regeneration of the TSA and PSA adsorbents.  An important application of the present invention is the purification and liquefaction of a natural gas feed stream with respect to its methane/C2 hydrocarbon component.

Title: Methods of using (+) cisapride for the treatment of gastro-esophageal reflux disease and other disorders
Inventor: GRAY NANCY M
IPC: A61K31/445
Filed: 1993-07-06
Abstract: Methods are disclosed utilizing the optically pure (+) isomer of cisapride. This compound is a potent drug for the treat-ment of gastro-esophageal reflux disease while avoiding the concomitant liability of adverse effects associated with the racemic mixture of cisapride. This compound is also useful in treating or preventing emesis while avoiding the adverse effects associate with racemic cisapride. The optically pure (+) isomer of cisapride is also useful for the treatment of dyspepsia and such other conditions as may be related to the activity of (+) cisapride as a prokinetic agent such as gastroparesis, constipation, post-opera-tive ileus, and intestinal pseudo-obstruction without the concomitant liability of adverse effects associated with the racemic mix-ture of cisapride. The (+) isomer of cisapride has been found to exhibit higher bioavailability over the racemic cisapride.

Each semiconductor layer (26) is thin enough that there is coupling be-tween adjacent semiconductor layers (26). The present invention utilizes INGS, which are fabricated to meet the criteria Eindg < ?.omega. < Edirg, especially where ?.omega. < 100 meV, as the optical material for optical switches. The present inven-tion also utilizes INGS as optical detectors if they are fabricated such that Eindg < Edirg < ?.omega., especially where ?.omega. is less than 100 meV.

Title: Optical fiber system and method for overcoming the effects of polarization gain anisotropy in a fiber amplifier
Inventor: GILES CLINTON R
IPC: H04B10/17
Filed: 1995-01-20
Abstract: An optical fiber system and method is disclosed that overcomes the effects of polarization gain anisotropy in rare-earth doped optical fiber amplifiers. An optical fiber has at least one rare-earth doped fiber portion for amplifying a light signal. Light signals are passed through the doped fiber portion in a first incident polarized state.      This light signal is reflected back from a Faraday effect mirror and through the doped fiber portion in its orthogonal polarized state so as to overcome the effects of polarization gain anisotropy. The rare-earth doped amplifier is preferably an erbium-doped fiber amplifier. A signal is initially passed through one part of a Faraday optical circulator and out a second port into the doped amplifier. On its return pass, the light signal enters the second port and then exits a third port. The optical amplifier can include a wavelength division multiplexor coupler for merging the pump signal with the original light signal. Various amplifier configurations are also disclosed which are either co-propagating or counter-propagating and reflect only the signal, reflect only the pump signal, or reflect both the pump signal and original light signal.
