Abstract: Serial No. 633,258 801-141A                    Filed:  November 19,1975 PROCESS                Abstract of the Disclosure A process is disclosed for separating components, e.g. olefinically-unsaturated hydrocarbons, from mixtures with other materials by liquid barrier permeation and metal-complexing techniques using a semi-permeable membrane and a partial pressure differential across the membrane for the material being separated.  The process is characterized by the use of elevated pressure on the feed side of the membrane, preferably at least about 200 psig, a low total pressure differential, if any, across the membrane, and preferably a partial pressure of the material being separated on the exit side of the membrane which is at least about 20 psi less than on the feed side.  The separated material may be removed with advantage by the use of a liquid solvent in which the material is soluble, and preferably the concentration of the material in the solvent is up to about 25 weight percent of saturation when the solvent is charged to the exit side of the membrane.  The separation of ethylene from its mixture with methane and ethane is of particular interest.

Abstract: COOLING SYSTEM FOR GEAR REDUCERS      Abstract of the Disclosure A cooling system for gear reducers having a housing with a lubricant therein, in which a motor for the pump and heat exchanger are mounted on a base struc-ture to form a unitary assembly which can be fully as-sembled in the manufacturing plant and delivered to and installed at the site of the gear reducer.  The temper-ature of the lubricant in the line from the gear reducer to the pump is sensed by a temperature responsive device and a control valve in the coolant line is regulated thereby for producing an intermittent flow to control the efficiency of the heat exchanger and thereby regulate the temperature of the lubricant in a predetermined range. A second temperature responsive device may be utilized to sense the temperature of the lubricant in the hot lubricant line and to shut down the equipment in the event the temperature of the lubricant, and consequently the temperature of the gear reducer, exceeds a predetermined value.  A by-pass line having a relief value may be in-cluded between the hot lubricant line and the return line to by-pass the lubricant around the heat exchanger in the event the flow through the heat exchanger becomes restricted and the pressure in the hot lubricant tends to become excessively high.   1.
