Abstract: A cooling device includes an aluminum heat sink and at least one nickel sheet segment. The nickel sheet segment is connected to the aluminum heat sink by a solder layer. The cooling device includes a securing surface for securing and for heat absorption. The securing surface being formed by that side of the nickel sheet segment which faces away from aluminum heat sink. The aluminum heat sink is formed from a plurality of aluminum sheets which are stacked one above another and are connected to one another. At least one aluminum sheet includes cutouts which form a cooling channel covered by at least one of the aluminum sheets. Furthermore, a method for producing a cooling device and also a power circuit comprising a heat sink as described here are presented.

Abstract: The present invention is directed to polyester resins which are prepared by depolymerizing virgin, scrap, recycled or reclaimed polyethylene terephthalate (PET) via an alcoholysis reaction with one or more polyhydric alcohols to form a depolymerization product and esterifying the depolymerization product with one or more polybasic carboxylic acids and/or anhydrides and optionally polyhydric alcohol to form a polyester polyol. The polyester may then be acrylated with acrylic acid to form a polyester acrylate resin. The polyester resins are then used in energy curable coating compositions or inks and in particular, the polyester acrylate resin is suitably used as a reactive binder/oligomer.

Abstract: Lithographic printing inks are described, which are characterized by the inclusion of both water, in a substantially emulsified form, and inorganic filler. Inks of the present invention show improved printing properties in offset lithography, including improved transfer, reduced piling and improved mileage. They also offer cost advantages over currently available inks and the ability to minimize or eliminate entirely mineral oil from their compositions. The inks of the present invention may be used in both web-based print processes including coldset and heatset, as well as in sheetfed printing. The inks may be dried to a durable ink film at ambient temperature, with thermal energy or with actinic or electron beam radiation, or with any combination thereof.

Abstract: The present invention concerns a telescopic mast which at least includes one or more telescoping joints, where a telescoping joint is formed of two telescoping sections dimensioned so that one section can be moved into another section, where between each of the two adjacent telescoping sections in a telescoping joint there is provided at least one actuator urging the adjacent telescoping sections away from each other, where these actuators are disposed internally of the telescoping joints and offset at the internal periphery. By disposing actuators offset at the inner periphery of the telescoping sections, several advantages are achieved. The actuators are provided at a protected location, and the actuators may be designed with lengths that overlap each other when the telescopic mast is collapsed.

Abstract: The present invention relates to a printed substrate comprising a substrate and a printing ink and is characterized in that at least one side of the substrate has a surface with such porosity that the Gurley-Hill air permeability value of the substrate is above 7000 s/100 ml, and it comprises an printing ink formulated as heat-set offset printing ink with reduced tack comprising at least one pigment and a mixture of at least two solvents boiling in the range of from 200° C. to 270° C.
