摘要:
Building element with cover layers (11, 19) connected to opposite sides of a core of a first (12, 13, 14, 15, 16) and a second (17, 18) core material. The cover layers (11; 19) comprise at least one stiffening layer having a thickness of at least 5 mm and a modulus of elasticity higher than 3000 MPa. The first core material (12, 13, 14, 15, 16) has a higher modulus of elasticity than the second core material (17, 18), whose modulus of elasticity is lower than 10 MPa. Edge pieces (12, 13, 15, 16) of the first core material surround intermediate pieces (17, 18) of the second core material, which cover at least 60 % of the area inside the edge pieces (12, 13, 15, 16). The cover layers (11, 19) are connected to the edge pieces (12, 13, 15, 16) by means of a fire- resistant adhesive, which covers at least 5 % of the area of the cover layers (11, 19) for a shear-resistant connection where the cover layers (11, 19) are at least 70 mm from each other with the first core material (12, 13, 15, 16) as a spacing element.

The engine includes a first and a second cylinder chamber. The first chamber receives gas through a first inlet valve which gas will be compressed by a piston in the cylinder and will leave the first chamber through a first outlet valve. The second chamber receives compressed gas from the first chamber through a second inlet valve. The gas expands in the second chamber while performing a work on the piston before leaving the second chamber through a second outlet valve. The engine is controlled such that gas will flow from the first to the second chamber while the engine performs a working cycle and the engine is thus controlled such that a piston is used for compressing gas which performs a work on the same piston, which is connected by a rod to a cranking mechanism to transfer work from the rod by an essentially only rectilinear movement.

The present invention relates to a device (100) for handling a connectorized fiber cable (103) in an optical fiber distribution system (200). The optical fiber distribution system (200) comprises a patch panel (201), the patch panel (201) comprising at least a first adapter (205). The first adapter (205) is configured to receive an optical connector (109) and to provide optical connection to the optical connector (109) when connected to the first adapter (205). The connectorized fiber cable (103) is terminated at a first end with the optical connector (109). The device (100) comprises a gripping unit (101) configured to manipulate the connectorized fiber cable (103).
摘要:
The present invention can be summarized by use of a diffraction limited SAR giving large integration angle and a short depth of field which gives that energy from underground targets is focused independently at different depths to enable 3d imaging. The radar device according to the invention should be implemented by considering the following parameters: Choice of the appropriate illumination geometry, i.e. elevation angle ¸, and the appropriate use of low frequency diffraction limited SAR processing to obtain 3D imaging, and the choice of an appropriately low radar frequency.
