Abstract: The invention relates to a method and a device for the superficial heating of tissue by means of a pulsed light source. According to the invention a series of light pulses is applied to the tissue surface. The first part of this series is configured such that the tissue surface and, by heat conduction, tissue areas situated below the tissue surface are rapidly heated to a defined target temperature without tissue removal. The subsequent part of the series results in oscillation of the temperature of the tissue areas located below the tissue surface around a value which is slightly lower than the target temperature.

Abstract: An apparatus is disclosed for fabricating a laminate product having a pair of sheet materials spaced by a plurality of flexible parallel vanes which are secured to the sheet material so that planar movement of the sheet materials in opposite directions cause the vanes to shift between open and closed positions. The vane material is formed from a web of material by dyeing the material, drying the dyed material, applying spaced longitudinally extending lines of adhesive on opposite faces of the material, and cutting the material into a plurality of side-by-side strips with each strip having a bead of adhesive on each face and along opposite side edges. The cut material with adhesive applied thereto is taken up on a transfer roll and moved to a vane/strip handling station where the strips of material are processed and delivered to a laminating station in parallel overlapping relationship with each other. The laminating station feeds the sheets of material above and below the strips to form the laminate before passing it through the laminating station where the adhesive is first heat activated to bond the component parts of the covering product together, and subsequently cooled to cure the adhesive. The resultant product is wrapped around a take-up roller for delivery to a remote location where the product can be cut to size and operably connected to a control system to form the final covering product for an architectural opening.

Abstract: Questa pinza a mano è particolarmente adatta ad operazioni di montaggio per sistemi di collegamento a manicotto scorrevole per tubi metallici e non metallici. Essa comprende sostanzialmente due parti di pinza tenute insieme da un primo collegamento articolato (1), di cui ciascuna parte è formata da un braccio anteriore per il ritegno di rispettive ganasce (17 ovvero 18) di montaggio, e da un braccio posteriore (2 ovvero 3) d'impugnatura, la cui lunghezza è pari a più volte quella del braccio anteriore. A tale riguardo, uno dei due bracci (2 ovvero 3) d'impugnatura è suddiviso in una parte interna più corta (19) ed una parte esterna più lunga (20). Questa parte esterna (20) d'impugnatura, con un pignone (24) per catena ed una catena (27) di trazione, forma un meccanismo articolato per lo sviluppo di una più elevata forza di montaggio. Per la rotazione del pignone (24) per catena, e quindi per il serraggio della pinza a mano, viene utilizzata una ruota (25) con una dentatura per nottolino. In questa dentatura (38) si impegna inoltre un nottolino (39) d'arresto, che impedisce un ritorno per deformazione elastica dei bracci (2, 3) d'impugnatura durante l'operazione di serraggio. Per lo sbloccaggio del nottolino (39) d'arresto è provvista una stecca scorrevole (46), spostabile alternativamente in sensi opposti.(Figura 1).

Abstract: A method of installing an electrically-heatable subsea flowline comprises launching the flowline with at least one electric power cable attached in piggybacked relation. After landing the flowline with the piggybacked cable on the seabed, a free end portion of the, or each, cable having a length greater than the water depth is released from the flowline. This allows a free end of the, or each, cable to be recovered to the surface to be spliced there to one or more power supply conductors.After lowering the, or each, cable and the, or each, connected conductor beneath the surface, the free end portion of at least one cable is reattached to the flowline on the seabed in piggybacked relation. To perform the method, a subsea flowline assembly comprises subsea-releasable fastenings spaced along the cable and the flowline to attach at least an end portion of the cable releasably to theflowline.
