摘要:
A cage for the ballistic protection of persons or objects with panels forming the cage walls, these being connected by profiled rails (2). The cage is characterized by the fact that the panels (1) are compressible, at least in the regions which engage in the rails, and by the fact that the rails each have at least one groove (5) in which a panel edge can engage, the edge region of the panel being compressed in order to fit. Especially, the panel edge is compressed by means of wedges (7) inserted between the groove wall of the rail and the panel surface in the edge region. Preferred panels are composite panels, especially those made of fibre composites.
摘要:
The invention relates to an apparatus for coextruding polymers at different temperatures comprising at least two extruders (1, 2), wherein the extruders are connected to a coextrusion head (4) which comprises an insulation zone (40), and at least one of a cooling zone (21) and a heating zone (31) and wherein a removable die/dieholder-combination is mounted to the coextrusion head (4). The invention also relates to a method for coextruding two or more polymers at different temperatures by shaping the polymers independently of one another, until the moment they meet at the vicinity of the die-frontplate (13), where the polymers are brought together and a coextrudate is formed.
摘要:
A device for fastening rails (3) on lateral stop plates (12) and Y-shaped steel sleepers (1) provided with a slot (14) that extends in the direction of the sleepers has spikes (5) arranged on both sides of the rail between the rail base (8) and the stop plates (12). The spikes clamp the rail base (8) on the sleeper by means of resilient spikes (7) supported on bearing blocks (10). A bottom inclined sole-plate (13) and a top cushioning plate (15) are arranged between the rail (3) and the sleeper. In order to develop further such a device, so that all its parts are reliably retained in the premounted state, in which the clamping spikes are drawn back, without additional parts nor steps, the inclined sole-plate (13) has a central beam (14) that extends into the slot (4) of the sleeper and vertical side walls (16) that encircle the rail base (8) on both sides. The inclined sole-plate (13) and the cushioning plate (15) are gripped by heels (17) of the bearing blocks (10) supported against the rail base (8).
