Title: Expansion system for liquefied gas - expands two streams at different pressures obtaining gaseous and liq. fractions
Inventor: LINDE GERHARD DR ING
IPC: F25J1/02
Filed: 1978-08-11
Abstract: The arrangement is for expanding a fluid forming a gaseous and liquid fraction after expansion. The fractions are obtained at different pressures and expansion is carried out with ejectors. One fraction is obtained at lower pressure and the other fraction under as high as possible pressure. This arrangement is used for expanding liquefied natural gas. The fluid is divided before its expansion into two streams expanded separately to different pressures. A phased separation of the expanded stream is carried out. The fractions obtained under higher pressure are fed to the ejector expanding the gas at higher pressure and recompressed. Fractions of the streams are recompressed to that pressure corresponding to the maximum pressure of the expanded stream.

Title: Quenching of hot rolled steel rod to form martensite - where rod is then descaled, cold drawn, and formed into high tensile steel coil springs, which are tempered
Inventor: SCHMITT WOLFGANG DIPL ING
IPC: C21D8/06
Filed: 1979-09-12
Abstract: The parent patent described the mfr. of high tensile steels, esp. spring steels. Improvement comprises the use of an unalloyed-or a low alloy-steel with a restricted C. content, and esp. contg. =0.33%C. Directly after leaving a hot rolling mill, the steel is subjected to a multistage, intermittent quenching treatment, so martensite is formed which extends into the core of the rolled rod. The steel rod is next descaled, and is then cold drawn without any prior treatment, followed by using the rod to make a final prod., esp. helical coil springs, which are tempered. The main patent used a similar quenching process to obtain a martensitic structure, which was then tempered by induction heating. But the induction heating interferes with continuous high speed rolling, and is eliminated in the addn.
