Abstract: For hot-welding of roofing material, use is made of a carriage 1 which carries a liquefied petroleum gas drum 16 and a burner 10. The carriage also carries a reel 31 of welding strip 32. The carriage also has a chamber 40 which is open towards the roofing material and through which the strip 32 runs. The liquefied petroleum gas burner is a so-called hot gas burner which, at its outlet, delivers a hot gas flow consisting of the exhaust gases of the liquefied petroleum gas flame and cooled by a secondary air flow 19. The hot gas 19 thereby produced is introduced into the chamber 40 which is open towards the substrate and adjoins the latter via a defined gap 45 so that the hot gas 19 acquires a predetermined distribution and dwell time in contact with the weld seam area for optimizing the welding procedure. Both the method and the apparatus for carrying out the method are claimed. <IMAGE>

Abstract: An optical fibre cable has an optical fibre with a core and cladding embraced by a cover of polymer material. In a temperature detection range (T1-T2) the polymer material has a negative coefficient of heat expansion ( alpha 0), the absolute value of which is larger than the coefficient of heat expansion ( alpha ) in neighbouring temperature ranges (T0-T1, T2-T3). When subjected to an increase in temperature (T), the cover will contract and cause microbending of the optical fibre. Light travelling in the fibre is attenuated and reflected, and the reflected light will be attenuated further in a heated domain of the fibre. The size of the domain and its position along the fibre can be determined by measuring the running time of the light. The polymer cover has a coefficient of heat expansion such as to enable several heated domains to be detected. The fibre attenuates the light in a range of 0.01-0.1 dB/m in the heated state of the fibre.

Abstract: A method and apparatus for mounting and tightening an open clamp about an object to be fastened in which a first jaw-like member causes the band end portion intended to constitute the inner band portion to be placed about the object to be fastened, a second jaw-like member then causes the other band end portion of the clamp intended to constitute the outer band portion to be placed about the object to be fastened in such a manner that the outwardly extending hook or hooks in the inner band portion is or are adapted to engage with the corresponding aperture or apertures in the outer band portion. Two further jaw-like members each having pincer-like nose portions at the free ends are then actuated to engage with the outwardly extending leg portions of a plastically deformable ear in the clamping band to plastically deform the latter after the mechanical connection by engagement of the outwardly extending hook or hooks in the corresponding aperture or apertures is established, to tighten the clamp about the object to be fastened. A holding device thereby holds the clamp in position until the first and second jaw-like members have been actuated and assume the holding function to permit release of the clamp by the holding device. Operation of the machine is fully automatic by appropriate sequence controls of fluid-actuated piston and cylinder units.

Abstract: A method and arrangement for the nondestructive determination of a property of an object including a conveyer for movably supporting the object. A testing unit, including a movable member and a stroking body, is mounted adjacent the conveyer. The conveyer moves the object into and then out of engagement with the movable member. When the object is out of engagement with the movable member, it is physically impacted by the stroking body causing the object to freely vibrate at at least one natural resonant frequency mode. A detector detects the vibration of the object resulting from the physical impact on the object by the stroking body. A computer coupled to the detector processes the detector output and determines the properties of the object.

Abstract: A method and a device for test receiving alternative frequencies without interrupting the reception of DAB frames from the current reception frequency in a DAB receiver. A DAB frame comprises a null symbol which is used to do a first very coarse synchronisation of the receiver to the transmitted signals. According to the invention, test receptions of alternative frequencies occur during the currently received programme's null symbols. By performing test receptions during the current programme's null symbols the current programme is not interrupted at all during the test receptions. A subsequently determined frequency changeover can thereafter, with a high probability, be performed without any noticeable interruption.
