  • Patent number: 10061855
    Abstract: A social networking system obtains user pronunciations of terms whose pronunciations might vary among different users, such as names of users. The social networking system additionally obtains demographic information about the users from whom the pronunciations were obtained, as well as social graph information for those users, such as information about connections of those users in the social graph. Based on the obtained pronunciations, the demographic information, and the social graph information, the social networking system determines, for a user having that name (or other term in question), one or more suggested pronunciations for the name that are likely to be the pronunciations that that user would use.

  • Patent number: 8925511
    Abstract: A cooling channel piston has a radially circumferential cooling channel located behind a ring field. The cooling channel piston is forged from a steel material and the cooling channel is worked in by machining between an upper part below the ring field and a lower part above the piston bosses and the piston skirts. The cooling channel extends behind the ring field in the direction of an upper face of the upper part, it being provided that the cooling channel piston has above its piston bosses and piston skirts an outwardly oriented support region. A closing element, which closes the cooling channel after the production thereof, is fastened between the lower edge of the ring field and the support region.

  • Patent number: 6302194
    Abstract: A pipe includes a pipe wall having an inner wall surface. Ribs are disposed on the inner wall surface forming a multiple thread. The ribs define a mean inside pipe diameter and the ribs have a lead which is equal to between 0.6 and 0.9 times the square root of the mean inside pipe diameter. Such pipes may be used in a fossil-fuel steam generator, a solar-heated steam generator, or a heated steam generator serving as a waste-heat steam generator, a heat exchanger or a steam generator for absorbing after-heat in a nuclear power plant.

  • Patent number: 6250257
    Abstract: A once-through steam generator having a combustion chamber. A containing wall of the combustion chamber is formed from vertically disposed evaporator tubes welded to one another in a gas-tight manner. The combustion chamber is to be capable of being used safely and reliably in a pressure range of between about 200 bar and 221 bar, while, moreover, a particularly high efficiency is to be achieved. For this purpose, according to the invention, a mass flow density m of a flow medium has the following relationship m=200+8.42 ·1012·q3[d/(d−2s)]s2·Tmax−5 in the evaporator tubes. In this case, q is the heat flow density acting on the evaporator tubes, Tmax is an admissible maximum temperature characteristic of the tube material, d is the outside diameter of the evaporator tubes and s is the wall thickness of the evaporator tubes.

  • Patent number: 5706766
    Abstract: A once-through steam generator has a vertical flue formed of tubes which are oriented vertically and which are connected in parallel for guiding a flow of flow medium therethrough. The tubes have a surface structure on an inner wall surface which causes flow turbulence and eddy currents in the flow medium. The surface structure includes first and second, mutually superimposed, contrary ribbings. The first ribbing encloses an acute angle with the tube axis, and the second ribbing extends parallel to the tube axis. The first ribbing forms an onflow flank angle with the tube wall which is flatter than a flow-off flank angle. Elevations of the ribbings rise at least 0.7 mm above the tube wall surface. A mass flow density of the medium in the tubes is adjusted as a function of the inner tube diameter, by maintaining the mass flow density below a predetermined limit curve.

  • Patent number: 4987862
    Abstract: A once-through stem generator includes a vertical gas flue having a total given height, a bottom, a lower part having a height equal to less than 70% of the total given height, an upper part, and fossil fuel burners disposed on the lower part. The lower and upper parts are formed of gas-tight tube walls with tubes. The tubes of the lower part rise obliquely, while the tubes of the upper part are vertical. The lower part has a lower end limited by the bottom, and the upper part has an upper end limited a partition of the vertical gas flue, by a cross-sectional restriction of the tube walls, or by a lower edge of a heating surface within the vertical gas flue.
