Abstract: A method for the countergravity casting of a melt involves placing a refractory mold in a vacuum chamber (70,78) defined within a casting box where the mold (30) may be optionally surrounded by support particulates in the vacuum chamber (70). The mold (30) includes a mold cavity and a serpentine melt inlet passage formed by nested refractory members below the mold cavity and in melt flow communication therewith. The serpentine melt inlet passage is communicated with a fill tube (90) extending from the casting chamber toward an underlying source of melt (102). The mold (30)/chamber (70) and the source (102) are relatively moved to engage the fill tube (90) and the source (102). A differential pressure is applied between the mold cavity and the source (102) to urge the melt upwardly through the fill tube (90) and serpentine melt inlet passage into the mold cavity. The mold (30)/chamber (70) and the source (102) are then relatively moved to disengage the fill tube (90) and the source (102) after the mold cavity is filled with the melt. The mold (30)/chamber (70) as a unit is rotated in a direction that the serpentine melt inlet passage prevents runout of melt from the mold cavity until the mold (30)/chamber (70) are inverted.

Abstract: The invention relates to a method of, and a device for, fastening mutually corresponding hinge parts on window frames and window sashes, in which fastening elements for the hinge parts are attached at specific positions on the window frame and window sash. In the case of known mounting methods or devices, sensors sense the outer or inner dimensions of the frames or sashes and the positions of the fastening elements are spatially assigned to said sensors. In order that all hinges of the window bear essentially the same part-load and the sash is articulated centrally with respect to the frame opening accommodating it, the invention provides for the spacings of all positions of the fastening elements on the frame and on the sash to be fixed relative to the centre of the frame or sash. <IMAGE>

Abstract: The invention relates to a process for immobilising a linear polymer, in particular a polyion, which is soluble in a hydrophilic solvent, on a chemically inert support material, and to a coated matrix which can be prepared by this process which has an antimicrobial action and which can be used for, in particular, medical devices to be applied, in particular, intracorporally (intracorporeally) and furthermore, in the form of microporous membranes, can be used as filters for water treatment or, in the form of small balls, as surface disinfectants. The process is distinguished by the fact that the two terminal reactive groups of the linear polymer are reacted with an excess of an alpha,omega-bifunctional compound, the resultant reaction product, dissolved in a hydrophilic solvent, is applied at least once to the support material and is then crosslinked by means of a crosslinking agent dissolved in a hydrophobic solvent which is inert towards the crosslinking agent and the support material.

Abstract: The invention relates to a method of manufacturing a semiconductor device whereby a dopant (4) is provided near a surface (2) of a semiconductor body (1) in a deposition step, after which in a diffusion step the dopant (4) is diffused into the semiconductor body (1) in that the semiconductor body (1) is kept at an elevated temperature for a certain period in a furnace (11) while a process gas (13) is being passed through the furnace (11), after which any oxide layer (8) formed on the surface (2) is removed. According to the invention, a hydrogen halide is added to the process gas (13). It is found then that the creation of lattice dislocations in semiconductor devices is reduced because impurities which play a part in the creation of lattice dislocations react with the hydrogen halide and are removed.
