Abstract: The invention relates to a test method for carrying out a fire claim test on a water flow valve and/or on a water flow valve system, in particular on a wet alarm valve and/or on a wet alarm valve station, as well as technical components to be used in this context and their use.

Abstract: A fire protection system for fire protection for liquid hazardous material. The system having at least one storage arrangement for storage of the liquid hazardous material in at least one storage vessel, at least one collecting area, and a first plurality of extinguishing fluid outlets, wherein the at least one storage arrangement is configured to direct the liquid hazardous material into the at least one collecting area in the event of escape of the liquid hazardous material from the at least one storage vessel, and wherein the at least one storage arrangement, the at least one collecting area and the first plurality of extinguishing fluid outlets are arranged relative to one another such that a firefighting action can be executed by a extinguishing fluid for use with a non-hazardous material in case of a fire event of the liquid hazardous material.

Abstract: Silicone elastomer-containing 3D articles are printed by a drop on demand technique using at least one first crosslinkable silicone as a structure forming material and at least one further structure forming material which is preferably a crosslinkable silicone different from the first crosslinkable silicone.

Abstract: Systems and methods for implementing an engineering web portal are disclosed. The system maintains a database of data and drawings for parts sold by a vendor. The drawings can be downloaded to a client and inserted into a CAD system, whereupon the vendor charged a fee for each drawing downloaded. The database of parts can be searched for parts meeting a user's requirements. The parts resulting from the search can be submitted to a search engine that searches for auctions that offer the part for bidding.

Abstract: A method, apparatus, and article of manufacture provide for displaying dimensioning for a data object. A data object to be dimensioned is displayed. Dimensioning for the data object is created in accordance with a dimensioning rule, wherein the dimensioning rule is pre-defined to determine how points of the data object are to be dimensioned. Once created, the dimensioning is displayed.

Abstract: The present invention relates to a landscape divider including at least one dividing element, which is fabricated of a sheet-like material and has at least one bent edge forming a U-shaped cross-section.

Abstract: This document describes a method for creating a dimensioning object for at least one data object, wherein both the dimensioning object and the data object are displayable on a display device as graphical objects, wherein the method comprises the following steps:

Abstract: A method for creating a dimensioning object for at least one data object, wherein both the dimensioning object and the data object are displayable on a display device as graphical objects. Dimensioning rules (that have been pre-defined for the data object) are applied to determine a dimensioning object for the data object. The dimensioning object for the data object to be dimensioned is displayed on the display device wherein the dimensioning object is determined by the dimensioning rules. The dimensioning object is stored with the data object.

Abstract: An arrangement for generating a defined longitudinal chromatic aberration in a beam path of a confocal microscope. The arrangement includes using a confocal microscope with a microscope objective, and supplementary optics which are arranged in the imaging beam path of the microscope objective. The supplementary optics include at least two dual lens optical elements for generating the longitudinal chromatic aberration.

Abstract: An optical system with variable image scale for video recordings by means of a CCD camera at a microscope. A video zoom adapting arrangement with a short overall length which enables all image scales for video cameras required in practice is realized in that three optical components with a positive focal length are provided. One optical component is stationary and a second and third optical component are arranged after the first optical component, as viewed in the imaging direction, so as to be displaceable.

Abstract: The invention is directed to a microscope having an objective corrected to infinity and a pivotable binocular viewing unit. A tube lens is arranged downstream of the objective. The microscope includes at least one two-lens tube lens having a focal intercept greater than 200 mm as well as a tiltable mirror element and a further deflecting element mounted between the tube lens and the binocular viewing unit.

Abstract: The invention relates to a front lens group for an immersion objective of BD arrangement with high aperture, suitable for a dark field incident illumination of a widefield immersion objective for microscopes. A spherical front lens surface is provided with a totally reflecting aspherical surface section via which the light is guided to the object, and is combined with a suitable epipolar system to produce a widefield immersion objective of even and colorfree illumination. The lens group is forwardly self-contained.

Abstract: The invention concerns a densely sintered ceramic dielectric with a loss factor less than or equal to 1.times.10.sup.-3 and a substantially linear temperature dependence of the capacitance based on TiO.sub.2 and/or ZrO.sub.2, and/or the compounds of TiO.sub.2, ZrO, Nb.sub.2 O.sub.5 and/or Ta.sub.2 O.sub.5 with oxides of the alkali metals, alkaline earth metals or rare earth metals in the form generally used for the production of ceramic dielectrics.
