Title: Fastener for securing insulation boards
IPC: E04F13/04
Filed: 1991-12-23
Abstract: The fastening element (1) for insulation panels (2) is fastened to a hard building component (A) by means of a setting implement. To prevent damage to segments (6) in the mouth region of the recess (4b), the recess (4b) has a widening (4d). The latter corresponds to twice the wall thickness of a segment (6) and has a depth corresponding to the length of a segment (6). Thus, on introducing the mouth (8a) of a setting implement (8), besides the recess (4b) the bent segments (6) also serve as a guide face. On applying a coat of plaster (9), plaster material gets behind the bent-up segments (6) so that a fastening acting in a manner so as to engage behind is ensured.

Title: Powder coating method and powder
Inventor: ARVERUS HAKAN
IPC: B05D1/06
Filed: 1996-08-09
Abstract: A method and a powder for powder coating in which objects (2) which are to be powder coated are prepared in order to temporarily retain the powder, whereafter the powder is applied onto the object in a layer which is retained on the object until the powder, by means of melting and transformation to a solid state by means of curing, is caused to form a coating layer on the surfaces of the object. The powder is prepared in order to have a low melting and softening temperature below about 100  DEG C and preferably 60-100  DEG C, and comprises an initiator system arranged to bring the powder material to curing under the influence of electromagnetic radiation. The powder prepared in this way is heated on the object to a temperature such that it melts and forms an adherent layer on the coated surfaces of the object. Thereafter, this layer is subjected to the radiation, thus curing it to a coating layer covering the powder-coated surfaces.

IPC: G01M3/36
Filed: 1999-07-29
Abstract: To test closed containers, e.g. with regard to residual air volume or the quality and tightness of the closures which are attached to containers, mechanical oscillations are excited in the closure, the mechanical oscillations are analyzed, measurement values are derived from this, these measurement values are compared with pre-set values for acceptable closures and a signal is produced which states whether the measurement value corresponds to a value for an acceptable closure. To increase the reliability of the test, the oscillation properties of the closure blanks (R) are also ascertained before their attachment to the containers (B) and the range of acceptable values of the closures (V) attached to the containers (B) is chosen according to the oscillation properties of the corresponding closure blank (R). The closure blanks (R) can be classified according to their oscillation properties.
