Title: Method of liquefying natural gas
Inventor: NELSON WARREN
IPC: F25J1/02
Filed: 1991-02-04
Abstract: A method of producing a methane-rich liquid stream from a stream of natural gas predominantly consisting o~ methane and also containing nitrogen, entailing: a) supplying said natural gas stream at a pressure above atmospheric pressure, b) cooling and liquefying said natural gas stream using one or more refrigeration cycles, and c) expanding said liquefied natural gas to lower pressure in two or more stages in series, phase separating the gas and liquid phases produced during the expansion, thereby concentrating the nitrogen into the vapor phase, and producing a methane-rich liquefied natural gas.

Inventor: RENNER JOCHEN
IPC: B65H3/08
Filed: 1991-03-01
Abstract: The device for locking a suction nozzle of a separating sucker at a suction head of a sheet feeder of a sheet-processing machine relates to a suction head having vertical motion effected by means of suction air and resilience of a spring.  The suction nozzle comprises a laterally arranged bearing support which, with said suction nozzle being in the lifted position, is held by a movably arranged abutment or counter-bearing until the trailing edge of a sheet supplied to the feeder has left the area of said suction nozzle of said separating sucker.  The suction head comprises at least one forwarding sucker which, by means of a drive, is guided at said suction head so as to be movable forwards and backwards with the working cycle of the machine and approximately parallel to a sheet plane. The abutment is connected to move forwards and backwards by the forwarding-sucker drive and during a selected portion of this movement unlocks said suction head momentarily before returning it to a locked position.

Abstract: A method enabling thorough purification of lacustrine water with simple operation in an energy-saving manner within a short period of time and being free from the possibility of secondary public nuisance, and further a filthy water purification boat for implementing said method.  According to this invention, while operating filthy water purification boat having an electrolyzing device for calcium fluoride, DC current power source, and coagulant pouring device mounted thereon on lakes or marshes, the electrolyzing device is operated and coagulant is fed into a pipe having a coagulant pouring nozzle.  Lacustrine water, while passed through electrodes, is fed with fluorine ion and coagulant, and polluting substances coagulate and turn into flocks of a large diameter. These diametrally large flocks are recovered into the boat by a flock recovering device or adapted to sink to the bottom of lakes or marshes after volume reduction caused by hydrophobic action of the flocks, and purified water is returned to lakes or marshes.

Two new genes, designated .beta.IG-M1 and .beta.IG-M2, are induced in response to TGF-B1 treatment of mouse embryo fibroblasts. These genes encode proteins containing about 345 to about 380 amino acid residues, with a molecular weight of about 37,000 to about 48,000daltons and about 38 cysteine residues. The induced proteins share about 50 % homology with each other and significant homology with a v-src induced protein in chicken embryo fibroblasts designated CEF-10. These proteins may be involved in producing some of the growth and differention modulating effects of TGF-.beta.1.
