A facing element for at least partially covering a structure. The facing element has at least one pair of first and second rigid engagement connectors affixed to a rear surface of the facing element. Each of the first and second engagement connectors forms first and second apertures between the connectors and the rear surface of the facing element. The first and second apertures are coaxially located. The facing element also has at least one joining bar joining the first and second engagement connectors. The top portion of the facing element is hung to the structure by means of the first engagement connector. Contact of the bottom portion of the facing element with the structure is offset by the second engagement connector. A method for fabricating such a facing element is also disclosed.

The invention relates to a camshaft-adjusting device, comprising a vane cell adjuster having a stator (16) that can be connected to a crankshaft of an internal combustion engine and a rotor (17), which is rotatably supported in the stator (16) and which can be connected to a camshaft, wherein a plurality of webs are provided on the stator (16), which webs divide an annular space between the stator (16) and the rotor (17) into a plurality of pressure chambers (24, 25), wherein the rotor (17) has a rotor hub (30) and a plurality of vanes (11, 12) extending radially outward from the rotor hub (30), which vanes divide the pressure chambers (24, 25) into two groups of working chambers (20, 21, 22, 23) having a different acting direction, into each of which working chambers pressure medium flowing in or out in a pressure-medium circuit can be admitted, and a central locking device (26) for locking the rotor (17) in at least one locking position in relation to the stator (17), wherein the central locking device (26) has at least two spring-loaded locking pins (2, 5) in an accommodating space (43, 44), which locking pins can be locked in a locking slot (19) secured to the stator and lock in the locking slot (19) when the rotor (17) rotates from the direction of an "early" or "late" stop position into the locking position from different directions, wherein the locking pin (2, 5) forms a valve device (36, 37) together with the particular accommodating space (43, 44), wherein the locking pin (2, 5) forms a valve pin (40), wherein the valve pin (40) is a step pin.

A through-wiring board comprising: a substrate provided with a first surface and a second surface; and lengths of through-wiring formed in through-holes, which penetrate between the first surface and the second surface, by filling an electrically conducting substance into the through-holes or by forming in the through-holes films of the electrically conducting substance. The lengths of through-wiring are separated from each other and each have, in a plan view of the substrate, at least one portion which overlaps with each other.

The invention relates to a sofa armrest which comprises a sofa base (1) and an armrest (2); the sofa base (1) and the armrest (2) are connected through a zipper structure and / or a nylon buckle structure, wherein one side of the armrest (2) is provided with a first connection band (21), and the other side of the armrest (2) is provided with an extended band (3); a second connecting band (22) which is matched with the first connection band (21) on the armrest (2) is arranged on the extended band (3); and a third connecting band (3) which is matched with the first connection band (21) on the armrest (2) is simultaneously arranged on the sofa base (1). The sofa armrest is convenient to detach, so that the packing quantity when the armrests are packed into containers can be greatly improved, the sofa armrest can serve as a cushion, and the production cost is not high.

The technology problem to be solved in the invention is to provide an apparatus for transporting molten metal using a ladle with which dust collection of soot, dust, etc., to the ascended / descended and tilled ladle can efficiently be performed without using a large scale apparatus as a whole, such as the conventional overhead crane type dust collecting system. A carrier 2 for a dust collector in acarrier 1 for ladle is arranged so as to be freely connected, and in the carrier 2 for dust collector, a bag filter type dust collector 3 is loaded and in the ladle 10, a cover type dust collecting hood 4 is arranged so as to be freely opened / closed. A primary moving connecting mechanism 8 in connect with a dust collector side duct 7 of the bag filter type dust collector 3 while permitting the opening / closing movement of the cover type dust collecting hood 4 is arranged and in the above dust collector side duct 7, a secondary moving connecting mechanism 9 for rotating around the tilting axialcenter P3 of the ladle 10 is arranged and a following means 5 is arranged in the dust collector side duct 7 so that the dust collector side duct 7 can follow with the ascending / descending of the ladle 10.

The invention relates to a residential building system with cast-in-situ beam columns and prefabricated sandwich concrete wall panels and a construction method, and the construction process of a vertical load-bearing structure is as follows: mounting the prefabricated sandwich concrete wall panels in para-positions on an underbeam / foundation so as to leave certain vertical gaps at the joints between the prefabricated sandwich concrete wall panels respectively, leaving horizontal gaps between the prefabricated sandwich concrete wall panels and the underbeam / foundation, mounting clamp dies at the gaps and casting concrete in situ so as to fixedly connect inter-plate connecting columns and horizontal joints formed at the vertical gaps and the horizontal gaps respectively, cast-in-situ wall corner columns and the prefabricated sandwich concrete wall panels into a whole and further constitute the vertical force-bearing structure of the residential building system. By adopting the invention, the bearing capacity of a wall body and the integrity and the anti-seismic performance of the structure of the whole residential building system are significantly improved, the application of steel mesh frame polyphenyl sandwich panels in the load-bearing structures is powerfully pushed, and the economic and social benefits are significant.
