Abstract: A UMTS 3g repeater and a Multi Sector Directional LMU Antenna Array can be integrated to be deployed inside large structures and large moving vehicles such as ferries and trains.

Abstract: The invention concerns a projectile-resistant partition construction realized as a stand comprising on both sides a single- or multilayer plating (11, 12) with cover plates (13 to 16) and a plurality of stands (17 to 19; 51 to 53) arranged between the plating (11, 12) provided on both sides, where the plating (11, 12) is held directly or indirectly on the stands (17 to 19; 51 to 53), where furthermore bombardment plates (21 to 24) form an extensive projectile barrier (25) in the interior region of the partition construction, and where the bombardment plates (21 to 24) consist at least partly of plaster fiber materials.

Abstract: An access door has a rectangular outer frame adapted to be set in a wall and having two longitudinal sides and two transverse sides defining four corners and a rectangular inner frame congruent to the outer frame, having longitudinal and transverse sides and four corners, and dimensioned to fit within the outer frame. Hinges at corners at ends of one of the longitudinal sides hold the inner frame in the outer frame and allow pivoting of the inner frame in the outer frame generally about the one longitudinal side. Two transversely effective spring latches are provided at the other longitudinal side near ends thereof between the inner and outer frames, and two longitudinally effective spring latches are provided at the transverse sides near the other longitudinal side between the inner and outer frames.

Abstract: The invention relates to a lightweight substance molded body made of a lightweight aggregate and a sintering auxiliary agent, wherein said molded body consist of a sintering product containing 60-95 wt. % lightweight aggregate with 40-5 wt. % water-soluble alkali silicate.

Abstract: An endoscopic puncture needle device comprising: an elastic catheter introducible into an instrument channel of an endoscope; a flexible hollow puncture needle extending through the catheter; a cylindrical handle casing extending in the longitudinal direction of the hollow puncture needle, the proximal end of the catheter being connected to the distal end of the casing; and a hollow rod connected to the proximal end of the hollow puncture needle, for reciprocating the hollow puncture needle within the catheter, said hollow rod being mounted in the handle casing coaxially with the proximal end of the catheter and displaceably in the longitudinal direction. In order to allow for easy and precise adjustment of the puncture depth of the hollow needle arranged in the catheter of the puncture needle device, the distal end portion of the handle casing is provided with a thread which can be screwed to a threaded hollow pipe socket arranged at the entry of the instrument channel of the endoscope.
