Abstract: A metal band inlay for trim strips or sealing strips of flexible material that is bent to form a section. The metal band includes a plurality of edge slots in the longitudinal direction, which are guided inwardly from an edge of the metal band transversely to the longitudinal direction. The edge slots are wedge shaped. Central slots run to a tip toward their respective two ends and are arranged between the sequential edge slots. The central slots extend transversely to the longitudinal direction, but do not extend up to the edge. To simplify the cutting, the metal band further includes throughcuts that extend transversely to the longitudinal direction of the metal band, that correspond to at least some of the central slots and that extend from at least one edge of the metal band in the direction toward the tip of the respective central slot disposed opposite to the edge.

Abstract: This invention relates to an apparatus and a process for rapidly and accurately dispensing fluids, in which at least one component is dispensed into the reaction vessel in two or three stages. In this process, the amount of fluid dispensed in the second and third stages is determined on the basis of the mass flow rate calculated in the preceding sub-step.

Abstract: In a method and a device for the ultrasonic monitoring of overlapping welded joints between a first sheet and a second sheet pulses are irradiated at an angle of between 15 and 80° into the first sheet by a first rotating probe head. The rotating probe head is arranged on a mount and has a tire rotating about the axle, coupled to the ultrasound transmitter and rolling along the first sheet, parallel to the overlapping welded joint. On ultrasound investigation of the overlapping welded joint the impulses transmitted to the second sheet are received by a second receiving rotating probe head, of similar construction to the first rotating probe head.

Abstract: The present invention relates to a process for the production of a polyurethane foam, comprising the reaction of a polyisocyanate and a polyol in the presence of a blowing agent and of particles. These particles are obtained by reacting carrier particles with a functionalising reagent G, wherein G contains reactive groups G1 by means of which G can be chemically bonded to the surface of the carrier particles, and wherein G additionally contains reactive groups G2 which, under the conditions of the polyurethane foam production, are reactive towards the NCO groups of the polyisocyanate, or towards the OH groups of the polyol, or both, and wherein G1 and G2 may be the same or different. The present invention relates also to a polyurethane foam obtained by this process and to products containing such a polyurethane foam. The present invention relates also to a composition containing a polyol and these particles. The present invention relates also to a composition containing a polyisocyanate and these particles.

Abstract: Systems, methods, and devices for eye marks in image processing are provided. A method includes providing an eye mark having at least two sections arranged along a longitudinal axis, wherein each section includes a border common to both sections and a unique characteristic relative to other sections. The method also includes encoding instructions in the eye mark based upon the combination of the at least two sections.

Abstract: A method for non-destructive testing of a weld joint of a bolt welded onto a contact area on a planar sheet metal using the lift ignition method uses directed ultrasonic signals. During the welding operation a weld pool having a modified material structure is formed beneath the contact area in the sheet metal. Ultrasonic signals are transmitted into the sheet metal using a directed and obliquely transmitting ultrasonic transmitter positioned at a coupling-in point A. An ultrasonic receiver is positioned at a coupling-out point B and receives the ultrasonic signals transmitted through the sheet metal at the coupling-out point B, an acoustic path being formed between the coupling-in point A and the coupling-out point B.

Abstract: The invention relates to an injection valve, comprising a control chamber (15) with a control piston (16) that is functionally linked with a nozzle needle (35). The control chamber (15) is linked, via an inlet throttle (13), with pressurized fuel, and with an outlet throttle (14) with a valve chamber (9). A servo valve (5) is disposed in the valve chamber (9), said servo valve opening a connection between the valve chamber (9) and a return element (40) depending on its position. The inventive injection valve further comprises a bypass throttle (12) that is interposed between the fuel feed line and the valve chamber.

Abstract: The present invention relates to polyurethane cast elastomers which are prepared from higher molecular weight polyhydroxy compounds, durene diisocyanate and low molecular weight chain-lengthening and/or crosslinking agents. These elastomers are particularly useful for the production of moldings exposed to high mechanical stresses.

Abstract: The invention relates to a mixer-kneading device for carrying out mechanical, chemical and/or thermal processes, consisting of mixing elements (A, R) disposed on a shaft (2, 3), extending approximately in the longitudinal direction of the shaft (2, 3) or being somewhat inclined and comprising at least one scraping edge (14, 18, 21). Said mixer-kneading device is characterised in that clearance angles (w1-w6) are formed, respectively, in a direction leading away from the scraping edge (14, 18, 21) and which is opposite to the direction of movement of the mixer element.
