Abstract: An electromagnetic switching device, in particular a high capacity contactor, includes switch contacts which are arranged inside interrupter chambers formed by an interrupter chamber housing. Also provided is a deionizing device which is in the form of an arcing chamber and assigned to each interrupter chamber with a switch contact. The arcing chamber is formed by arcing plates which are assembled to form a packet. In addition, a cover is provided for closing the interrupter chambers on the upper side. The uppermost arcing plate which faces the cover is configured as a shielding plate of each arcing chamber and has at least one upward bent clip. Recesses which correspond with the clips of the arcing chambers are formed on the underside of the cover. The arcing chambers can be fastened to the cover to provide an interlocking connection by plugging the clips into the recesses.

Abstract: An apparatus for unloading fish from a hold of a boat adjacent an unloading site has a carriage movable horizontally at the site along the boat, an articulated arm, and an endless conveyor extending along the arm. This arm has a rigid inner section having an inner end pivoted about a horizontal inner axis on the carriage and an outer end, a pivot defining an outer horizontal axis at the inner-section outer end, and a rigid outer section having an inner end pivoted on the inner-section outer end at the pivot and an outer end. An inner actuator braced between the carriage and the inner section can pivot the arm on the carriage about the inner axis and an outer actuator braced between the arm sections can pivot the outer section about the outer axis on the inner section. The conveyor extends along the arm from the inner-section inner end to the outer-section outer end and has a carry stretch on one side of the sections and a return stretch on an opposite side of the sections.

Abstract: An agent for selective removal of heavy metals from liquids, especially from wines, fruit juices and alcoholic beverages, consists of a polymer with heavy metal ion binding groups which can be produced by oximating a free aldehyde group-containing polymer with the aid of hydroxylamine, or by polymerizing a polymerizable aldehyde oximated with hydroxylamine, followed by oxidation in each case.

Abstract: The invention concerns a suspended shelving storehouse construction comprising a foundation, spaced apart vertical columns rising from the foundation, a load-bearing ceiling supported by said vertical columns, a series of tension bars each secured to the load-bearing ceiling at spaced intervals between the vertical columns so that the tension bars are suspended substantially vertically from the ceiling between adjacent columns, and shelving girders mounted horizontally between adjacent tension bars.
