Abstract: What is described is the use of a composition containing one or more formaldehyde scavengers for production of a coating on a main body of a mold or core for metal casting that emits formaldehyde when heated, wherein the coating forms a surface of the mold or core that comes into contact with a metal melt in the casting operation.

Abstract: A description is given of a use of a composition comprising an ortho-fused phenolic resole in an amount of up to 60 wt %; as first solvent for the ortho-fused phenolic resole, one or more compounds selected from the group consisting of alkyl silicates, alkyl silicate oligomers and mixtures thereof, the total amount of these compounds being greater than 30 wt %; optionally one or more further solvents for the ortho-fused phenolic resole; optionally one or more further additives; the weight percentages being based on the total amount of the composition, as a binder component for producing feeder elements by the cold box process. A description is also given of the use of a two-component binder system for producing feeder elements by the cold box process, and of a method for producing a feeder element for the foundry industry, and also of a feeder element.

Abstract: A sensor for measuring particles in contaminated media contains an optically transparent measuring cell, through which a capillary tube for conducting and measuring a medium passes, an optical detector, and a magnetic detector. The measuring cell is cylindrical, the capillary tube extends coaxially in the measuring cell and an inspection space is arranged in a center of the measuring cell. On the inspection space an optical lens system having a light source and at least one optical detector is focused. Differential coils for producing and detecting a coaxial alternating magnetic field form the magnetic detector on the shaft of the measuring cell, which differential coils are controlled in such a way that the alternating magnetic field is canceled out in the inspection space.

Abstract: Housing for at least one electric or electronic device, the housing surrounding a housing interior comprising a storage space, the electric or electronic device being arrangeable in the storage space, the housing comprising a housing upper part, which delimits the housing interior, the housing comprising at least one intermediate ceiling portion, which is arranged in the housing interior below the housing upper part and, together with the housing upper part, encloses at least one intermediate space, the intermediate ceiling portion having at least one cooling air passage, through which cooling air can flow from the storage space into the intermediate space, the housing upper part having at least one cooling air outlet, through which the cooling air can escape outwardly from the intermediate space, wherein the intermediate ceiling portion forms a catching arrangement for dripping water, which infiltrates the intermediate space through the cooling air outlet.

Abstract: An assembly for mechanically connecting an electrical cable to the housing of an electrical device comprises a cable jacket with an annular groove filled with a resinous substance such as polyurethane, the resin forming a prism fitted to an aperture in the device housing. The surface defining the groove is roughened and provided with a multiplicity of teeth.

Abstract: A method for positioning a switch in a speed limiting device, wherein, for a limit switch, which interrupts the controlling process of the speed limiting device consisting of an electronic control unit, an electromechanical servo unit and a mechanical clutch arrangement, a positioning method is utilized and in order to carry out this method, an arrangement is provided in which the limit switch is fastened on a slide which is displaceably supported with the servo component of the speed limiting device. Arranged in the slide, which, in addition, carries a switchover contact bank serving to actuate the switch, there are provided locking bars with which, together with catch paths constructed at a housing of the servo unit, an exact fixing of the slide can be achieved at the end of the positioning process by means of reversing the rotational direction of the servo motor.

Abstract: A tachograph assembly including a casing and a cover member pivotally mounted on the casing with a first pivotal bearing member being formed on a first part of the cover member and a second pivotal bearing member being formed on a casing extension which, together with the cover member, forms the front face of the tachograph assembly in a generally common plane. The second bearing member has an outer radius which corresponds to the inner radius of the first bearing member and a bearing spindle in the form of an elongated lip is formed on the second part of the cover member for engagement with the second bearing member to enable pivotal motion of the cover member relative to the casing. The first part of the cover member includes alignment elements which operate in cooperation with corresponding elements in the casing to align the cover member within the casing when the cover is in the closed position.
