A high efficiency, low maintenance single stage or multi-stage centrifugal compressor assembly for large cooling installations. The assembly is highly efficient by virtue of a variable frequency drive (VFD) that drives a permanent magnet motor and matches compressor speed with compressor load, a direct drive impeller that eliminates gearing losses, and magnetic bearings that reduce frictional losses. The back-emf produced by the motor provides an intermediate power source for the magnetic bearings in the event of a loss of electrical power. A cooling system provides direct cooling of the rotor with gas refrigerant, and cooling of the stator with liquid refrigerant. Modular construction allows the compressor to be retrofit with upgrades. An inlet guide vane system operates without need for oil lubrication. The use of light metal castings and elimination of gearing reduces the weight to one-third or less of comparably powered conventional units.

The present invention relates to a method of produc- ing the fluoropolymer according to any one of Claims 1 to 3, by subjecting a fluoropolymer precursor containing acid/acid salt groups and having -CF2COOX groups at polymer chain terminals, in the formula X represents H, NR11R12R13R14 or M4 1/L; R11, R12, R13 and R14 are the same or different and each represents H or an alkyl group containing 1 to 4 car- bon atoms and M4 represents a metal having a valence of L, said metal having a valence of L being a metal belonging to the group 1, 2, 4, 8, 11, 12 or 13 of the long-form peri- odic table, to heat treatment for the conversion of said - CF2COOX groups to -CF2H groups, X being as defined above, wherein said fluoropolymer precursor is one obtained by polymerizing a perhalovinyl ether derivative represented by the general formula (I): CF2=CF-O-(CF2CFY1-O)n-(CFY2)m-SO2Z (I) wherein Y1 represents F, Cl or a perfluoroalkyl group, n represents an integer of 0 to 3, the n atoms/groups of Y1 are the same or different, Y2 represents F or Cl, m repre- sents an integer of 1 to 5, the m atoms of Y2 are the same or different and Z represents F, Cl, Br, I, -OM5 1/L or - ONR15R16R17R18; M5 represents a metal having a valence of L and the metal having a valence of L is as defined above, and R15, R16, R17 and R18 are the same or different and each represents H or an alkyl group containing 1 to 4 carbon at- oms, when the group -SO2Z in the general formula (I) is not said acid/acid salt group but is a group convertible to such acid/acid salt group, said fluoropolymer precursor is one subjected to a conversion treatment, after the above- mentioned polymerization, for the conversion of said group -SO2Z to the above-mentioned acid/acid salt group, and said heat treatment comprises heating said fluoropolymer precursor at 120 to 400°C.
The present invention is directed to a surface-treating agent comprising a fluoropolymer comprising (A) repeating units derived from a fluorine-containing monomer of the formula: (see formula I) (B) repeating units derived from a monomer free from a fluorine atom, and (C) optionally, repeating units derived from a crosslinkable monomer. The surface treating agent is excellent in water repellency, oil repellency and is not susceptible to fouling even when the side chains are C4 or lower fluoroalkyl groups.

PROCESS FOR PREPARING TETRAFLUOROETHYLENE/FLUORO(ALKYL VINYL ETHER) COPOLYMER
- 1 - Abstract: The invention provides a process for preparing a tetrafluoroethylene/fluoro(alkyl vinyl ether) copoly- mer comprising polymerizing tetrafluoroethylene and a fluoro(alkyl vinyl ether) in an aqueous suspension system which comprises a mixed medium of water and a fluorohydro- carbon or a chlorofluorohydrocarbon in a volume ratio of from 1 : 1 to 10 : 1 at a temperature of from 0 to 25°C in the presence of a polymerization initiator of the formula: [C1(CF2)n-COO?2 (I) wherein n is an integer of 1 to 10. The copolymer obtained by the process has a small number of unstable terminal groups and excellent durability under flexing.
