Abstract: The present invention relates to a device for separating two immiscible phases and/or for extracting one phase with another phase (phase separation or extraction device), comprising at least one vessel for receiving the at least two phases, at least one pipe for supplying a fluid to the vessel, at least one pipe for discharging a fluid from the vessel, and at least one arrangement comprising a transparent disk for observing the separation operation or the extraction operation, wherein at least the side of the transparent disk that faces the phases to be separated or extracted consists of sapphire (sapphire glass) or mica (mica disk), and to the use of such a device in the preparation of di- and poly-amines of the diphenylmethane series.

Abstract: A rebound net arrangement may include a support means and at least one polygonal rebound net with a net height hN and a net width wN that can be fastened thereto, wherein the support means comprises two posts that can be braced, for which there is provided at one of their ends a ground contact area for setting up the posts on the ground, wherein at least one fastening means is arranged on the posts in each case at a predefined height hP1 seen from the ground contact area, between which an upper edge of the at least one rebound net can be tensioned, wherein the height hP1 is less than the net height hN of the at least one rebound net.

Abstract: The invention relates to a novel net, in particular for sports, such as a volleyball net, tennis net or goal net, which can be provided with advertising or other information. Said net is characterized by a mesh structure that is formed by a film containing holes distributed over its surface. A film of this type can be printed before the holes are produced, thus enabling advertising or other information to be applied by simple printing presses.

Abstract: The present invention relates to a device and a method for administration of a substance to a mammal by means of inhalation. The device according to the invention comprises: aerosol means, for creating an aerosol, control means, for manipulating the aerosol in order to thereby control the particle size of the aerosol, wherein the device is provided with supply means for adding a substance to the aerosol, prior to or upon release of the aerosol from the device. The device according to the present invention is suitable for pulmonary delivery of substances, such as drugs.

Abstract: The invention relates to an inhaler including a catalytic burner, a fuel tank (6) coupled to the burner and preferably containing hydrogen, a container (15) for inhalation additives such as aromatic substances and/or active ingredients, at least one inlet (2) for a gaseous mixture containing oxygen (in particular air), and an outlet (3) for an inhalation mixture containing aromatic substances and/or active ingredients.

Abstract: In an adjustable height post for a volleyball net, in particular for a beach volleyball net, comprising a ground sleeve to be anchored in or on the ground and a net pole, which is lockable in variable positions of height and is displaceably guided in the ground sleeve, telescoping in the vertical direction, it is provided that the net pole and the ground sleeve are roller-seated relative to each other by means of bearing rollers, and that a rubber-elastic cord is mounted between the net pole and the ground sleeve, by the expansion of which a counterforce can be produced, which opposes the weight of the net pole.

Abstract: In a playing field boundary, particularly for ball games, that encompasses a peripheral, vertical band comprising a plurality of plate-like band elements that can be connected to one another, in order to make the boundary easy to transport and assemble, as well as highly stable in the assembled state, it is provided that the band elements (1) can be connected to one another form-fittingly, and that a peripheral, tensible belt arrangement (belt 28) is provided which encompasses the band elements (1).
