Inventor: TURNER PETER J
IPC: F25J3/02
Filed: 2020-04-14
Abstract: A system for removing nitrogen from, a natural gas fluid feed stream includes a main heat exchanger that receives the natural gas fluid feed stream. A distillation column receives a cooled fluid stream from the main heat exchanger and features a return vapor outlet and a side vapor outlet port. The return vapor outlet provides nitrogen vapor to the main heat exchanger which is warmed therein. The side vapor outlet port provides vapor to the main heat exchanger and a reflux compressor receives and compresses the resulting fluid from the main heat exchanger. A reflux aftercooler receives and cools fluid from the reflux compressor, directs cooled fluid to the main heat exchanger and the resulting fluid is directed to a reflux separation device. The reflux separation device has a vapor outlet and a liquid outlet. The vapor outlet of the reflux separation device directs fluid to the main heat exchanger so that fluid is directed to the first reflux inlet port of the distillation column. The liquid outlet of the reflux separation device directs fluid to a. second reflux inlet port of the distillation column.

Title: Methods of transverse placement in elt
Inventor: ENDERS MARKUS
IPC: A61F9/008
Filed: 2020-04-20
Abstract: Glaucoma patients suffer from increased intraocular pressure due to blocked fluid flow from the anterior chamber of the eye. Methods of the invention include inserting a probe into an eye of a subject having glaucoma, adjusting placement of the probe to a position transverse to Schlemm's canal in the eye, and applying a plurality of shots from an excimer laser source while the probe is in the transverse position, thereby treating glaucoma by creating a plurality of perforations in Schlemm's canal and/or the trabecular meshwork. By providing a laser probe at a position transverse to Schlemm's canal, energy from the laser is delivered to a greater amount of surface area than if the laser was arranged in a parallel or perpendicular position to Schlemm's canal, resulting in optimal formation of perforations. The perforations allow for drainage of fluid and increased outflow of aqueous humor in the eye.
