摘要:
A method and an apparatus are for the loading and postprocessing of three-dimensional digital volume data, in particular from the medical field. Layer images are usually acquired by CT or MR devices and combined to form a volume data record. These combined data are fed to one or more postprocessing methods, such as e.g. the VRT, MIP and/or MPR technique. These postprocessing methods can already be used for a portion of the loaded data directly after the beginning of the loading operation.

Costabilizers which are copolymers of oxazolines and bisoxazolines enhance the stabilizing properties of primary stabilizers such as polyoxazolines and zinc compounds in chloride-containing thermoplastic molding compositions, preferably based on polymers of vinyl chloride.
摘要:
A low pressure turbine casing has a conical annular shell circumscribed about a centerline. A forward flange depends from a forward end of the annular shell and a forward hook extends aftwardly from the forward flange. First and second rails having first and second hooks, respectively, extend aftwardly from the annular shell. First and second cooling holes extend through the first and second rails, respectively. Cooling air feed holes extend through the forward flange. The first and second cooling holes may be radially disposed through the first and second rails, respectively, with respect to the centerline or disposed through the first and second rails at an oblique angle with respect to the centerline. A low pressure turbine casing and shroud assembly further includes a first annular cavity in fluid flow communication with the first cooling holes and the second cooling holes. A second annular cavity is in fluid flow communication with the first and second cooling holes.
摘要:
A stabilizer mixture for molding compounds based on polymers of vinyl chloride; use of said mixture; and molding compounds is disclosed. The heretofore known physiologically unobjectionable stabilizer systems have the disadvantage of disagreeable odor, as well as inadequate initial stability. In addition to physiologically unobjectionable stabilizers (e.g., metal soaps, salts of aromatic carboxylic acids, or metal phenolates), co-stabilizers of the present invention are used, in the form of derivatives of thiosalicylic acid esters masked at the mercapto group by monothioacetal formation. The field of application is hard and soft PVCs.
摘要:
A control system, a method of operating the same, and a method for setting up the same are disclosed for simplified driving of a function unit parametrized by a plurality of input variables. The control system includes a setting unit and a control unit, the setting unit being used to set a number of prescribed control parameters and to feed them to the control unit. A value tuple that is fed to the function unit for the parametrization thereof is determined by the control unit as a function of the controlled variables in accordance with a stored interpolation function based on interpolation points. To set up the control system, it is provided to select a number of value tuples of the input variables as interpolation points from a parameter space defined by the input variables, and to determine the interpolation function in such a way that it defines a continuous subspace of the parameter space which has a dimensionality corresponding to the number of controlled variables and contains every interpolation point.

Costabilizers which are composed of pyrroles and/or dihydropyridines and/or copolymers of oxazolines and bisoxazolines and/or polyols enhance the stabilizing effect of primary stabilizers such as polyoxazolines and zinc compounds in thermoplastic molding compositions, such as those based on polymers of vinyl chloride.

Gas turbine engine frames are disclosed. An example gas turbine engine frame may include a generally annular outer casing disposed coaxially about a hub; a plurality of circumferentially spaced apart struts joined to the hub and the outer casing, individual struts extending radially outwardly from the hub to the outer casing; and a stiffening rail monolithically formed with the outer casing circumferentially between two of the struts. The stiffening rail may extend radially inward beyond the inner surface of the outer casing between the struts.
摘要:
A stud for interconnecting adjacent flanges of a flanged joint in a tubular casing. The flanges each contain apertures to receive the stud and each flange is inclined relative to the casing outer surface, with one flange extending radially outwardly and the other flange extending radially inwardly, as a result of which one end of the stud extends externally of the flanged joint and the other end extends internally. The stud includes an external formation that is of non-circular form and that is carried by the stud between the threaded ends to extend radially outwardly. The external formation is adapted to be engaged by an anti-rotation member to prevent unintended rotation of the stud. The stud is removable from the flanged joint without the need to completely disassemble the joint to remove a broken stud.
