Abstract: A process for preparing a hyperbranched polycarbonate polyol includes reacting a polyfunctional alcohol and an ester or carbonate in the presence of a catalyst and then heating the reaction mixture under azeotropic reflux conditions to form an alcohol or water. The alcohol or water by-product is then removed from the reaction mixture, thereby pushing the reaction forward.

Abstract: The invention relates to aqueous polyurethane dispersions that are curable with UV radiation. The polyurethanes are chain-extended with aromatic, cycloaliphatic or aliphatic diamine compound and cross-linked with aliphatic triamine compound. The polyurethanes are useful dispersions for coating various substrates. The use of the invented dispersions results in high hardness, very good flexibility and good chemical resistance in both clear coats and pigmented coatings before and after UV curing combined with very good adhesion to different substrates.

Abstract: The invention relates to a cooling device (100) for cooling at least one element (150, 151) passing through said device, comprising a metal block (115), having a first side and a second side, and comprising a cooling channel (130) for cyrogenic gas. The at least one element (150, 151) can be guided along the sides of the first side of the metal block (115), the cooling channel (130) is at least partially in heat conductive connection with the second side of the metal block (115), and the cooling channel (130) has an attachment (131) on a first end for the entry of cryogenic gas and an attachment on a second end for the exit of cryogenic gas. The invention also comprises a hardening device having such a cooling device (100) and a method for cooling at least one element (150, 151) passing through said device.

Abstract: A device drills longitudinally a fruit, such as a banana, for its subsequent filling. The device includes a header with a projecting cylindrical part. The header is vertically perforated by a cylindrical upper part and a lower cylindrical or conical part, and from the internal face of such header and from diametrically opposite areas respective arms in parallel extend in longitudinal laterally opposite edges arched sections defining such perforation a connection for a tubular member with a spindle-shaped edge and an inner wing. The inner wing is fixed to a perforated part and arched so as to form a handle, having each arm part of the device in their lower ends surfaces arched outwards that define a component in which are fitted and supported a pair of arched diametrically opposite grooves in a cylindrical part forming the base and concentric to a central cylindrical cavity.
