  • Patent number: 5294689
    Abstract: The present invention provides an aqueous process for preparing water-soluble addition copolymers of containing, as polymerized units: (a) from about 3 to about 95 percent by weight of one or more cyclohexene anhydrides or the alkali metal or ammonium salts thereof, and (b) from about 5 to about 97 percent by weight of one or more monomers C.sub.4 -C.sub.6 monoethylenically unsaturated dicarboxylic acids and the alkali metal and ammonium salts thereof. These copolymers are useful as water-treatment additives for boiler waters and cooling towers and as detergent additives acting as builders, anti-filming agents, dispersants, sequestering agents and encrustation inhibitors.

  • Patent number: 5264510
    Abstract: This invention is directed to a terpolymer containing as polymerized units at least one first monomer selected from the group of vinyl acetate, vinyl ethers and vinyl carbonates, at least one second monomer of an ethylenically unsaturated monocarboxylic acid, and at least one third monomer of an anhydride of a dicarboxylic acid. The terpolymer is formed by a free-radical polymerization in a nonaqueous solvent. It has further been discovered that the partial hydrolysis, saponification, and saponification followed by oxidation of this terpolymer leads to terpolymer derivatives with improved detergent properties and improved biodegradability.

  • Patent number: 4753747
    Abstract: The present invention relates to a process for making liquid soap, preferably without the need for melting the fatty acid and most preferably without the need for external heating or cooling and to the use of said process in making soap-containing cosmetic products, particularly shave cream in either aerosol or post foaming gel form.

  • Patent number: 4733538
    Abstract: Means are provided for controlling and modulating the temperature of the hot gas exiting the combustor associated with a gas turbine engine. The means establish a preselected temperature gradient in the hot gas so as to provide a flow of hot gas at a relatively higher temperature through gaps between adjacent turbine vanes and a flow of hot gas at a relatively lower temperature upon the vanes.

  • Patent number: 4265646
    Abstract: A system of separating or removing foreign particles from the gaseous fluid flowing in the primary flow path of a gas turbine engine is provided wherein the particles are removed from the stream near the engine inlet and flow through a conduit to ejector means operative to effect a flow of a second stream of fluid in the conduit. Mixing means are provided for mixing the second stream of fluid with the gaseous fluid flowing in the primary flow path.

  • Patent number: 4109459
    Abstract: A combustor for use in a gas turbine engine is provided with a first wall defining a combustion zone; an outer casing partially defining a cooling plenum about the first wall; a second wall spaced apart from the first wall and defining together therewith a second plenum, the second wall bearing a plurality of perforations for passing fluid from the first plenum in impinging streams upon the first wall; and a plurality of ribs extending between the first and second walls and compartmentalizing the second plenum. The ribs add substantial stiffness to the combustor as well as providing for independently controlled cooling of the substantially isolated compartments formed thereby. The impinging streams provided by the perforations in the second wall substantially increase local fluid velocities and conductive heat transfer.

  • Patent number: 4100732
    Abstract: Airflow exiting a centrifugal compressor is diffused in multiple shaped passages tangential to the compressor impeller dumped into a plenum to reduce its Mach number and then directed through deswirl vanes to the entrance of a combustor. Deswirl at reduced Mach number significantly reduces pressure losses resulting in reduced complexity and manufacturing cost for the diffuser deswirl system.

  • Patent number: 3946552
    Abstract: An improved fuel injection apparatus is provided to uniformly disperse a low pressure fuel in a highly atomized manner for introduction into a combustion apparatus. The fuel injection apparatus of this invention employs a system of counter-rotating air swirl means disposed about a shroud member whereby the primary atomizing forces are the high shear stresses developed at the confluence of the counter-rotating air streams and the greater velocity and uniformity at which the fuel is dispersed within the shroud provides for a substantially increased atomization efficiency.

  • Patent number: H903
    Abstract: A gas turbine engine is provided with a means for cooling tips of turbine blades in a hot turbine section of the engine. Inlet air holes are provided in a radially outer wall section of the combustor, just upstream of a turbine nozzle. Cooling air flows through these inlet air holes, into annulus regions protected from combustion gases, and then downstream along a radially outer wall of the turbine. The cooling air forms a film that cools the turbine blade tips in a localized manner that adds to total engine power output.
