Abstract: The present invention is directed to a method for producing a hollow metallic billet (10) from a heated metallic billet (1) by a piercing operation (for example with the use of a piercing mandrel (4)). The method is characterized in that a local temperature change is effected at least at the hole initiation end (11) of the billet (1) in at least one zone (110, 112) and the zone is rotationally symmetrical to the central axis (M) of the billet (1). Also described is a device for producing a hollow metallic billet (10) from a metallic billet (1) and comprising a holder (3) for the billet (1), characterized in that the device includes at least one temperature adjusting device or a projection element (2) operative to change the temperature of the billet (1) in the holder (3) at least zonewise and directed at a subzone of at least one of the end sides of the billet (1).

Abstract: The present invention relates to a coating material in the form of a suspension for the coating of metal surfaces of components prior to a thermal treatment for protection against corrosion. The coating material is hereby characterized in that the solid phase of the suspension primarily is composed of aluminum particles, and the liquid phase is composed of organic solvents and binders, the solid phase of the suspension containing at least two types of aluminum particle shapes, which are differentiated by their specific surface. In addition, a component is described, whose metal surface has been coated with a coating material according to the invention prior to thermal treatment and which has a contact resistance of <1 mOhm (DIN EN ISO 18594) after thermal treatment.

Abstract: The invention relates to a medical pump device comprising a rotary valve (13) having preferably only one rectilinear channel (20) which respectively connects the inlet (4) and the outlet (7) of the pump device, or connects the inlet to a pump chamber (15), or said pump chamber to the outlet, upon rotation of the rotary element (19) of the valve. The invention enables a medical pump device to be especially easily produced, said pump device being preferably inserted between an infusion syringe driver or an infusion container and a catheter, and being used to supply small quantities of liquid in an accurately dosed manner.

Abstract: A bottle packing system including an oscillating grid for transferring bottle groups from a grouping station to a carton-filling station, the grid including tensioned resilient means for engaging and retaining bottles in the grid during its oscillation, and a positive-ejection member rockable into the grid for ejecting the bottles from the grid at the carton-filling station.

Abstract: The present invention concerns a novel improvement in the catalytic hydrogenation of nitroanthraquinones to produce aminoanthraquinones, comprising over-hydrogenating the resulting aminoanthraquinone to the corresponding nuclear hydrogenated aminoanthraquinone and, after removal of the aminoanthraquinone, oxidising the remaining nuclear-hydrogenated aminoanthraquinone to aminoanthraquinone. Aminoanthraquinones are useful as intermediates in the production of anthraquinone dyestuffs.
