Abstract: A method for casting cast parts in which a casting mould is provided. The casting mould is enclosed in a housing, forming a filling space between an inner surface section of the housing and an associated outer surface section of the casting mould. The filling space is then filled with a free-flowing filling material and molten metal is poured in the casting mould. As a consequence a binder of the mould material begins to vaporise and combust disintegrating the casting mould. During the filling of the filling space, the filling material has a minimum temperature, starting out from which the temperature of the filling material rises, to beyond a boundary temperature at which the vaporising binder ignites and combusts.

Abstract: A method to produce cast pieces with optimum mechanical properties having through-openings with minimal outlay in terms of equipment. A casting mold in which at least one casting core is used. A through-channel leading through the through-opening of the cast piece is formed by burning the binder in the molding material out of the casting core representing the through-opening by means of the heat input into the casting mold when pouring the molten metal into the casting mold, or by mechanically destroying, at least in part, the respective casting core representing the through-opening and the regions of the casting mold arranged in the extension of the casting core.

Abstract: An adjustment foot unit of a domestic appliance, in particular an adjustment foot unit of a refrigerator unit and/or freezer unit, has a vertical adjustment device having a rotatable rod and a spindle rotatably supported in a housing and having a thread at least sectionally, with the rod and the spindle being connected to one another such that a rotation of the rod results in a rotation of the spindle, having an adjustment unit, in particular a nut, which is arranged rotationally fixedly and has a thread which is in engagement with the thread of the spindle as well as having a foot part displaceable relative to the housing, with the foot part and/or the adjustment unit having a sloped plane in which the adjustment unit is in contact with the foot part.

Abstract: An air dispersion system has a main supply line, a plurality of air outlets, which are connected via respective air exhaust routes to the main supply line, and at least one heating element, which is associated with at least one of the air outlets and can temper the air in the exhaust route of this air outlet.

Abstract: The granule consists of individual granules approximately spherical in shape, having a pore volume of 0.5 cm3, a mean diameter of pores of 50 nm or less, a specific surface area of 100 m2/g or less, and a bulk density of 0.7 g/cm3 or higher. It is produced by dispersing a fumed silica obtained by hydrolysis of a silicon compound into pure water to obtain a slurry, and drying the slurry. The granule is used for producing high purity synthetic quartz glass powder. The method further comprises: a first heat treatment under an oxygen-containing atmosphere, a second heat treatment in a temperature range of from 600 to 1100° C., and a third heat treatment in a temperature range of from 1100 to 1300° C. under an atmosphere containing hydrogen chloride; and a step of densification comprising calcining the product at a temperature not higher than 1500° C. under vacuum or in an atmosphere of gaseous hydrogen or gaseous helium.

Abstract: A method is provided for the manufacture of SiO.sub.2 granular material. Silicic acid is dispersed in a liquid to form a dispersion. The dispersion is stirred in a stirring tank with formation of a homogeneous liquid phase. The homogeneous liquid phase is maintained by stirring at a substantially constant rate until the granular mass develops, when the solids content of the dispersion is within the range of 65 to 80 weight percent. Moisture is gradually extracted to form a granular mass which is dried and sintered.

Abstract: In order to control and optimize the amount of inhalable active substance released when drugs are administered as inhalation powders, the invention calls for the use of auxiliaries consisting of mixtures of coarser particles (average particle size>20 .mu.m) and finer particles (average particle size<10 .mu.m).
