A housing part for a measurement device includes a single metal body having an outer circumferential side wall with an upper end and a lower end and an inner disc-shaped base wall located between the upper and lower ends, wherein the side wall and the base wall define two partially enclosed areas, where the base wall comprises a central hole into which a microwave-permeable glass or ceramic window is fused, microwave guides and dielectric matching elements are provided on both sides of the microwave-permeable or ceramic window to propagate microwaves between the desired points such as a radar antenna and radar electronics, and where the matching elements not only adjust the impedance of the microwave window to the impedances of the microwave guides but also put additional compression stress on the surfaces of the fused window, which are preferably ground flat to be flush with those of the center portion.

An electromagnetic coil assembly is provided. The electromagnetic coil assembly includes a bobbin, a coil of magnet wire and a cover piece. The bobbin includes a hub, a first flange and a second flange. The hub has a longitudinal axis. The first and second flanges are spaced axially from each other. The hub and flanges together define a circumferential bobbin channel. The bobbin is made from a material that is an electrical insulator. The coil of magnet wire is positioned around the hub in the circumferential bobbin channel. The magnet wire has first and second ends. The cover piece is self-supporting and is sized to extend circumferentially around the coil of magnet wire. The cover piece is resilient and exerts a compressive force radially inwardly on the coil of magnet wire.

This patent describes a platform structure, which can be used either as a stand-alone unit, or as part of the body of a wheeled vehicle such as a trailer. As part of the body of a trailer its multipurpose feature allows the trailer to be easily converted into different modes of usage including: an extended platform, a flat-bed trailer with side walls, an open-top utility box trailer, or a compact highway trailer. The highway trailer, with a compactly collapsed body equipped with a cargo-rack, is intended to offer the best possible towing performance at highway speed. The cargo-rack has a screen enclosure for the containment of small or loose cargo items. When used as a stationary platform, said structure has a center portion with adjustable leg assemblies that can support and level the entire structure above the ground. Side sections are cantilevered on opposite sides of the center portion to form extensions to the main platform area. Fastening means for the erection of a camping tent on said platform are also disclosed. The side sections can also be firmly erected in an upright position to form side walls of an open ended utility trailer. Here the end sections can be easily attached to convert the latter into an open-top utility box trailer.
