HF-tight housing for electronic measurement devices

High frequency exclusion housing for electronic and mechanical components of electronic measurement apparatus has extruded rectangular frame (1) and mounting shell (2), with a floor (3) for support of the operating element of the apparatus and perpendicular to the floor (3) is a narrow lip (4). Over the mounting frame (2) is an invertable front cover (5) likewise with a flat floor (6) and shallow lip (7). A component housing (8) is made of plates (9, 10, 11) leaving one side open and over which slides a housing tube or square housing (14. The shape of the frame (1) is such that on its inner side separate flat steps mesh on one side with the lip (4) of the mounting frame (2) and on the other side with the plates (9, 10) of the component housing (8). On the outer side of the frame (1) are proud sections for meshing with grooves on the front cover (5) and the housing tube (14).

Vorrichtung zur tiefenverdichtung von erdstoffen

Die Vorrichtung besteht aus einem Vibrator, mit oder ohne Daempfungselement, welcher vertikale Laengsschwingungen erzeugt, einer Vibrationslanze mit oder ohne Spuelkopf und Spuelwasserkanal. An nur einer Stelle des Lanzenschaftes sind groszflaechige Schwingbleche angeordnet, welche kontinuierlich ein entsprechendes Erdstoffvolumen um die Vibrationslanze erregen. Bei senkrechtem Ansatz der Vorrichtung verhindern diese Schwingbleche, bedingt durch den groszen Eindringwiderstand, eine Schiefstellung im weiteren Verdichtungsvorgang. Die Flaeche der Schwingbleche betraegt mindestens das 3fache der bekannten Fluegelelemente.
