Granted: 1979-11-27
Abstract: ABSTRACT         A thermoplastic polyester urethane molding composi-tion is disclosed having low compression set and high elastic modulus and which comprises the reaction product of a poly(epsilon-caprolactone)polymer, a hydroxy terminated polyol, an organic diisocyanate and a siloxane polymer. More specifically, by adding the siloxane polymer and main-taining a mole ratio of isocyanate to isocyanak-reactable hydroxy grouping in the range of from about 1.05 to about 1.3 or higher, it is possible to produce an improved molding composition having allophanate cross-links.  The allophanate linkage breaks down at molding temperatures and reforms upon cooling thereby allowing an easily moldable thermoplastic urethane polyester which, after molding, will maintain its shape and have characteristics of a thermoset material. Additionally, the use of the siloxane polymer improves cer-tain physical properties of the reaction product such as tensile and modulus of elasticity.

Abstract: ABSTRACT OF THE DISCLOSURE      RADIOACTIVE LOGGING FOR DETERMINING OIL             SATURATION IN A RESERVOIR      A method is disclosed for determining oil saturations in a petroleum reservoir using logging signals indirectly re-lated to the abundance of carbon nuclei in the reservoir rock.      The first step of the invention is to record a log sensitive to the abundance of carbon nuclei after the region surrounding the well bore is caused to have oil saturations representative of the bulk of the reservoir.  A purposeful change is then made in the fluid saturations in the region surrounding the well bore by injecting a liquid capable of displacing substantially all of the original fluids.  The log is recorded a second time.      The displacing fluid is then itself displaced by brine, and a third log is recorded.  Oil saturation is then determined from difference between the logs and from known fractional volume carbon contents of the reservoir oil and the first injected liquid.  It is not necessary that the log response be independent of the material in the bore hole, the casing, the casing cement, or the reservoir rock.  It is only necessary that changes in oil content cause proportional changes in log response.

Abstract: HEAT EXCHANGE SYSTEM     Abstract A plurality of parallel heat exchange tubes are grouped together and connected at the ends to form a bank.          One or more banks are positioned so that one end lies in a supply air stream and the other end lies in an exhaust air stream.  Each bank of tubes is sealed and contains a working fluid of the type having a liquid phase and a vapor phase. At one end of each tube, the working fluid absorbs heat from one of said air streams to effect vaporization of said fluid, the vaporized fluid flows to the cooler end of said tube where said vaporized fluid gives up heat to the cooler air stream and condenses in the tube.  The condensed fluid then flows back to the warmer end by means of gravity.  One end of the lowest tube in each bank includes a reservoir connected thereto which communicates with the normally cooler air path and in-cludes a heating coil operatively associated therewith for providing a modulated control of the system responsive to the temperature of the enclosed space being ventilated.  Additionally, a second control system turns selected banks of heat tubes on and off to prevent frost from forming thereon.
