The invention relates to locking elements that are designed in such a manner that they can adopt an initial position into which the boards are brought by especially lowering them in an exclusively vertical manner. A terminal position is achieved by especially subsequently displacing the panels along the common joint. In this position, the two panels can be interlocked in a manner perpendicular to the panel surface and parallel to the panel surface and at the same time perpendicular to the common connecting joint.

The invention relates to flat and/or elongated building components (1, 2), preferably wooden, and a structure connecting these components (1, 2) in accordance with the groove and tongue principle. Two legs (3, 4) forming a groove (5) branch off from a front face of one of the components (1), and a tongue (6) branching off from a front face of the other component (2) can be inserted into the groove (5). Locking elements (7, 8) hold the components (1, 2) in an assembled position. In accordance with the invention, the locking elements are configured as triangular projections (7) and cavities (8) in facing or adjacent surfaces of the groove and/or tongue.
摘要:
Flooring panels having a tongue and groove locking mechanism. The tongue-and-groove configuration principle are provided at the areas being connected. The sides of the groove diverge from the groove base and converge at the end away from the groove base. The opening width of the groove is greater than the foremost area of the tongue in the direction of insertion. The tongue exhibits wedge-shaped areas that diverge from front to back which areas exhibit an undercut in the back area of the tongue that conforms to the groove cross-section. The undercut's borders, adjoining the wedge-shaped areas, converge at the same angle as the groove sides toward a connecting bridge that is part of the component.
摘要:
A method of connecting structural components having a relatively low thickness, the method including pre-applying, at an off-site location, one of an adhesive and a substance which activates an adhesive to at least one of at least one of the sides of the groove of one of the structural components and at least one of the sides of the tongue of another of the structural components, and connecting, at a site different from the off-site location, the structural components together by causing the tongue to be inserted into the groove.

The present invention relates to an expression vector, comprising a polynucleotide encoding a fusion protein comprising the signal sequence of the gac gene of Pseudomonas diminuta and a polypeptide of interest, a prokaryotic host cell transformed with such an expression vector and a process for production of a polypeptide of interest using said host cell and said expression vector.
摘要:
A panel includes coupling elements arranged so that two panels an be connected to one another by a form-fit connection at the same time in a first direction perpendicular to the common joint and in a second direction parallel and perpendicular to the common surface of the panels. The panels may be used to provide a laminate flooring. The form-fit connection achieves greater security during assembly with reference to any enlargement of cracks and inaccuracies when laying parquet flooring. Laid parquet flooring elements no longer slip relative to one another even when subjected to relatively large stresses, thereby avoiding damage and the need for follow-on work. The coupling element is preferably designed as a separate synthetic material clip in the shape of the letter H.

摘要:
To connect the mutually contacting faces of two sheets, in particular counter tops, in a simple manner such that the top surfaces lie in a common plane, the invention provides an arrangement which consists of two fitting parts (7, 12) each connected to one sheet (1, 2). The first fitting part (7) is provided with a recess (9) open to the bottom whose limiting wall (10) facing the other sheet (2) has a slot open toward the bottom. The fitting part (12) fastened to the other sheet (2) is provided with a threaded hole into which a screw (17) is inserted. The screw (17) is inserted into the slot such that the head is accommodated by the recess (9) and is supported by the limiting wall (10) accommodating the slot (11). To adjust the height, adjustment screws (12) are provided in flanges (15) of fitting part (12) which interact with the base plate of fitting part (7).

The invention relates to a process for the production of wool and animal hairs with a low-in felt or felt-free finish, with a soft woolly handle and special shrink-resistance and strength. In this process, the wool is treated with a protease and is then treated at a temperature of between room temperature and 140.degree. C.
