摘要:
A method for drying a fibrous web, particularly a paper, cardboard or tissue web whereby the moving fibrous web is treated with got air in the area of a pre-definable drying zone the fibrous web is treated, at least in some areas inside the drying zone with steam.
摘要:
Methods and systems for analyzing vibrations of a vehicle acting on a person. The person uses a sprung vehicle seat. A detection unit detects acceleration values fitted to the vehicle seat in the x-, y- and z-axes at preset intervals of time. An increase over time of the acceleration values cumulated with one another is determined and a time calculated from this when a pre-determinable permitted maximum of the cumulated acceleration values will foreseeably be reached.
摘要:
An apparatus and a method are provided which allow two opposite plane surfaces of a body to be interferometrically measured simultaneously using light from a single light source. From a parallel light beam (P) produced by a light source (1) partial light beams (A, B) having positive and negative diffraction angles are produced using a beam splitter (8) in the form of a diffraction grating. The partial light beams strike the respective surfaces (90, 91) of the body (9) to be measured and are reflected thereat. The reflected partial light beams (A, B) are interfered with the throughgoing partial light beam (P) having an order of diffraction of zero and the thus produced interference patterns are digitized and subtracted from each other, whereby the parallelism of both surfaces (90, 91) of the body can be determined.
摘要:
Device and method for recording vibrations transmitted from a vehicle to a person. The person is using a cushioned and preferably sprung vehicle seat of a vehicle by way of at least one detector unit for detecting vibration values, whereby the detector unit is arranged on the vehicle seat frame or an associated component and an analysis unit for analyzing the vibration values detected calculates vibration results for the vibration acting on the person using a preset transmission function.
摘要:
A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, especially release-coated substrates, in which a fluid film is applied to a rotating roller by means of a fluid applicator, the pressure-sensitive adhesive system is applied in one or more layers to the fluid film by means of an adhesive applicator, and the roller is contacted with the substrate, so that the pressure-sensitive adhesive system is transferred from the roller to the substrate.
摘要:
A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, especially release-coated substrates, in which the pressure-sensitive adhesive system is applied in one or more layers to a rotating roller by means of an adhesive applicator, the pressure-sensitive adhesive system on the roller is crosslinked in an irradiating means by means of high-energy radiation, and the roller is contacted with the substrate, so that the pressure-sensitive adhesive system is transferred from the roller to the substrate.
摘要:
A secondary electrochemical cell with at least one positive electrode includes an active material and one negative electrode, which are held directly in a hermetically tight housing which has at least one detector element or which is dynamically connected to one such detector element. The detector element is designed or can be set to acquire a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by the malfunction of the secondary electrochemical cell can be precluded under all operating conditions with simultaneously great reduction of all dimensions.

摘要:
An axial joint and a process for manufacturing an axial joint are described. The axial joint comprises a metallic housing (1) with an opening (2) and with an interior space (9), with a ball pivot (3), which has a joint ball (4) and a pivot pin (5). The joint ball (4) is surrounded for the most part by the housing (1) and a pivot pin neck (5.1) of reduced diameter compared with that of the pivot (5) is present in the transition area between the joint ball (4) and the pivot pin (5), and the pivot pin (5) projects through the opening (2) of the housing. The axial joint also has a bearing shell (6; 6.1, 6.2), which consists essentially of plastic and is arranged between the housing (1) and the joint ball (4), and the metallic housing is made in one piece.
