Abstract: Process for producing a tool insert for injection molding a microstructured part fabricated of a synthetic material, a metal or a ceramic material and which comprises an arrangement of microchannels and which further comprises an arrangement of through-going orifices extending in a substantially perpendicular manner with respect to the outer surface of the part.
Abstract: The invention relates to a method for producing a component, comprising a body (1), to which pressure-sensitive adhesive is applied, at least in sections. To produce the component (10, 20, 30), a pressure-sensitive adhesive base (6) is applied to the body (1). Said applied pressure-adhesive base (6) is at least partially cross-linked until it achieves a predetermined viscosity. The pressure-sensitive adhesive base (6) is preferably applied directly to the body (1). The component is cost-effective to produce, can be simply mounted and is extremely strong.

Abstract: A process for producing microstructured tool insert for injection molding a part, the part being fabricated of a synthetic material, a metal or a ceramic material and including an arrangement of microstructures which are formed on an outer surface of the part and have two different predetermined depths.
Abstract: An integrally built, linear array of cuvettes is made of a plastic material. Every cuvette of the array has the same shape and dimensions. Neighboring cuvettes are connected to each other by a single web. Each of the single webs has a curved shape and each cuvette has means forming integral part thereof and serving for accurately positioning the cuvette into an opening of a cuvette holder and means for removably connecting the cuvette to the cuvette holder. Each cuvette has an upper chamber and a lower chamber having a common symmetry axis passing through the centers of both chambers. Each of the upper and lower chambers has a substantially cylindrical shape. The cross-section of the upper chamber at the central part thereof is larger than the cross-section of the lower chamber. The lower chamber has an open lower end. The upper chamber has an open top end and an annular bottom wall having a central circular opening which connects the upper chamber with the lower chamber.

Abstract: The connection comprises a window frame (5, 5′), which extends along the lower edge (1a) of the windshield (1), which is fastened to the bottom side (1b) of the windshield, and which forms a channel (5) extending essentially parallel to the lower edge (1a). A wedge (14, 24, 34, 44, 54) is inserted into the channel (5) of the window frame (5, 5′) and fixes a retaining connecting member (2a) of the water deflector (2) inside the channel (5). The wedge (14, 24, 34, 44, 54) is preferably provided in the form of a strip. The connection enables the water deflector (2) to be mounted more easily and quickly.

Abstract: The water discharge device (faucet) is provided with a pullout spray head (2) that may be pulled down from the curved pipe (3) and which spray head is provided with a discharge mouthpiece (5). A switching valve (8) is arranged within said spray head (2) whereby said switching valve (8) is positioned in a housing (7) that is dimensioned in such a manner that it may be grasped by the user with one hand. Said switching valve (8) may be actuated by an operating lever (6). Said operating lever (6) is a bail (U-shaped lever) that is pivotably mounted on a water-guiding part (24) and which in turn is connected to a switching arrangement (28) mounted in said housing (7) with which a valve member (9) of the diverting valve (28) may be moved in its longitudinal direction during movement of the bail (6). Said bail (6) is arranged in such a manner that it may be operated with the thumb of the hand that is grasping said housing (7).
