Abstract: The invention relates to an ergonomic tube (30) for a microscope (1). A binocular head (20) is provided on the tube (30). A deflection element (15) is provided in the tube (30) and a deflection mirror (18) is assigned to said element, the mirror (18) being located behind the optical path (5) of the lens, when viewed from the user's (17) position. A single tube-lens system (11) is positioned in the optical path (16) of the tube. A modification to the inclination of the ocular optical path (21) in relation to the horizontal (H) by a value ?causes the position of the deflection mirror (18) to be modified by an angle ?/2.

Abstract: This invention relates to a machine for the production of a paper web, paperboard web or tissue web, having a roller with a circumferential surface and having an endless belt, in particular a transfer belt, which is wrapped around the circumferential surface of the roller in sections and has a bottom side which in the wrap zone can be brought into contact with the circumferential surface, as the result of which the endless belt and/or the roller provide a storage capacity suitable for accommodating at least in part the fluid which gets into the wrap zone between the bottom side and the circumferential surface.

Abstract: An odor adsorption agent, in particular for use in a hygiene article, is formed of a thermoplastic granulate and a zeolite bonded to the thermoplastic granulate by means of a welded bond.

Abstract: A system for computer assisted monitoring of a cross profile of a quality parameter of a material web, especially a paper or cardboard web during its production and/or conversion, which includes a measuring system for measuring the cross profile, at least one computer based operations and logic unit for the determination of the standard deviations of at least two interference profiles that are representative for different interferences in the form of different peak groups in the measured cross profile. The different peak groups differentiate in that their peaks have different width ranges. Elements for storage, display and/or further processing of the determined standard deviations are also included.
