Abstract: A laminated photovoltaic thermal (PV/T) module for a PV/T hybrid solar collector comprising a cooler/absorber and a photovoltaic unit. The cooler/absorber includes at least one flat surface with raised peripheral edges and is adapted to function as a mould for a photovoltaic laminate structure. The photovoltaic unit includes a photovoltaic laminate structure including: a first layer of a first laminate material moulded on the flat surface of the cooler/absorber, wherein the first laminate material is electrically insulating and has a high thermal conductivity; a plurality of photovoltaic cells positioned on the first layer of laminate material; and a second layer of a second laminate material moulded on and substantially covering the photovoltaic cells, wherein the second laminate material is transparent and has a high heat resistance.

Abstract: A mounting arrangement for mounting a device in an opening is disclosed. The arrangement comprises an outer sleeve, an inner sleeve arranged inside the outer sleeve, and an adjustment ring arranged inside the outer sleeve. A flange is arranged at a first end of the outer sleeve, arranged to receive said device. The flange is adapted to abut an outer surface of the structure. The inner sleeve is arranged in threaded engagement with the adjustment ring or with the outer sleeve. The adjustment ring comprises a fixing wing extending outwardly through a longitudinally extending aperture in the outer sleeve, the fixing wing having an abutment portion adapted to abut an inner surface of the structure. By relative rotary motion of the inner and outer sleeve, the adjustment ring is movable along a longitudinal direction of the arrangement for adjustment to a thickness of the structure.

Abstract: A coated cutting tool includes a body and a hard and wear resistant PVD coating on the body, wherein the body is made from a cemented carbide, cermet, ceramics, polycrystalline diamond or polycrystalline cubic boron nitride based materials. The coating includes a first (Ti,Al)-based nitride sub-coating and a second (Ti,Al)-based nitride sub-coating. The first (Ti,Al)-based nitride sub-coating can be a single layer, and the second (Ti,Al)-based nitride sub-coating can be a laminated structure, wherein the first (Ti,Al)-based nitride sub-coating includes a (Ti1-xAlx)Nz-layer where 0.1<x<0.4, 0.6<z<1.2, and wherein the second (Ti,Al)-based nitride sub-coating includes a (Ti1-x1-y1Alx1Cry1)Nz1 layer where 0.5<x1<0.75, 0.05<y1<0.2, 0.6<z1<1.2.
