Abstract: A stable assembly of a metal detector is disclosed which can ensure a tension free physical connection between a former and a case of the metal detector. The metal detector includes a case with at least four closed sides and two openings, a non-conductive former having a pass-through aperture, and electromagnetic coils arranged on the former to produce an electromagnetic field within the former which is disturbed by a metallic body passing through the aperture. The former formed into a single piece and having a width equal to the inner width of the case, is inserted into the case from the front side of the case. The space between the former and the case is filled with a potting medium. The physical connection between the former and the case includes a protruding-recess which is strengthened by an adhesive.

Abstract: In one aspect, assemblies for removing water from hydrocarbon liquids are described herein. An assembly described herein comprises a coalescer element having interior and exterior surfaces and comprising a porous support tube and a medium positioned within the porous support tube, the medium having a structure for coalescing water droplets in the hydrocarbon liquid passing though the medium. A separation medium encloses the exterior surface of the coalescer element and is spaced apart from the exterior surface of the coalescer element. The separation medium comprises a barrier region for collecting coalesced water droplets in the hydrocarbon liquid exited from the coalescer element and a release region for releasing coalesced water droplets from the assembly.

Abstract: A housing for a RFID system is provided including one or more radio frequency antennas, one or more RFID readers, and a central frame. The central frame supports the antenna(s) and reader(s) therein. The central frame includes a bollard, a frame portion, and a tile exterior composed of an impact-resistant plastic. The frame and tile exterior are protected by the bollard from forceful impacts to the central frame.
