Shaping Liquid Metal Against A Forming Surface Patents (Class 164/47)
  • Patent number: 8297339
    Abstract: A semi-molten or semi-solid molding method is used to cast a scroll member having a tabular panel, a spiral section and a columnar part. The method includes filling a cavity formed inside of the molding die with semi-molten or semi-solid metal from a section for forming the columnar part via a runner that forms a channel. The cavity forms a space for casting the scroll member. An angle of intersection ?1 between the runner and the section for forming the columnar part is set such that to 97°??1?135°, and/or a ratio R/?S is set such that 0.12?R/?S?0.96. R is a radius of curvature of a chamfered section in which the runner intersects the section for forming the columnar part, and ?S is the square root of a cross-sectional area S of the section for forming the columnar part.

    Abstract: A turbine airfoil usable in a turbine engine and including a depth indicator for determining outer wall blade thickness. The airfoil may include an outer wall having a plurality of grooves in the outer surface of the outer wall. The grooves may have a depth that represents a desired outer surface and wall thickness of the outer wall. The material forming an outer surface of the outer wall may be removed to be flush with an innermost point in each groove, thereby reducing the wall thickness and increasing efficiency. The plurality of grooves may be positioned in a radially outer region of the airfoil proximate to the tip.

  • Publication number: 20110280683
    Abstract: The distribution of load stresses on threads engaged with a standard screw or nut is very unequal. Indeed, the first threads in engagement support a large majority of the load. So if the load is too important, the threads give way and the function is not provided any more by the screw or the nut. In the prior art, threads are known whose depth or pitch varies a lot in order to cause a self-clamping. In particular, the invention aims at optimizing the resistance and the fatigue resistance of the screws by distributing the load at the very best on their threads without causing this self-clamping. It was shown that the control of the pitch variation, within a chosen pitch tolerance, makes it possible to control the stress distribution on the threads. It is possible to determine a different variation for each load case encountered.

    Abstract: Provided herein are titanium alloys that can achieve a combination of high strength and high toughness or elongation, and a method to produce the alloys. By tolerating iron, oxygen, and other incidental elements and impurities, the alloys enable the use of lower quality scrap as raw materials. The alloys are castable and can form ?-phase laths in a basketweave morphology by a commercially feasible heat treatment that does not require hot-working or rapid cooling rates. The alloys comprise, by weight, about 3.0% to about 6.0% aluminum, 0% to about 1.5% tin, about 2.0% to about 4.0% vanadium, about 0.5% to about 4.5% molybdenum, about 1.0% to about 2.5% chromium, about 0.20% to about 0.55% iron, 0% to about 0.35% oxygen, 0% to about 0.007% boron, and 0% to about 0.60% other incidental elements and impurities, the balance of weight percent comprising titanium.

Said sliding closure comprises at least one stationary, fireproof closing plate (21) and a fireproof sliding plate (22) which can be displaced relative to said closing plate. Through the displacement of the sliding plate (22), the outflow out the furnace drum (2) can be regulated or closed and therefore the outflow amount of the copper can be controlled. A drawing of slag into the casting, which reduces the anode quality, can be prevented using said sliding closure (20).
