Abstract: The invention relates to a reactor (1) for gasifying biomass, in particular wood, comprising a feeder chute (7) and an ash bed arranged beneath the feeder chute (7). According to the invention, a device is provided by means of which biomass adhering to the feeder chute (7) can be detached, and/or a heat exchanger is provided by means of which a product gas generated from the biomass gives oil heat to the biomass subsequently conveyed in the feeder chute (7) and to oxidation air. The invention further relates to a fine filter (29) for cleaning a product gas generated from biomass. According to the invention, the filter medium contains biomass. Furthermore, the invention relates to a method for gasifying biomass in a reactor (1), in particular a reactor (1) according to the invention, to form a product gas. According to the invention, biomass adhering to the feeder chute (7) is detached and/or heat is given off to biomass and to oxidation air by the product gas.

Abstract: Plastic webs, including webs of rigid and plasticized PVC, can be printed at high speed on conventional rotogravure presses with an ink whose vehicle consists of polyalkyl acrylate and polyalkyl methacrylate binder dispersed in a homogeneous, aqueous solvent in a weight ratio of 100:3 to 100:25. The imprints adhere well and resist abrasion.

Abstract: A lacquer consisting essentially of a uniform dispersion or solution of 8% to 16% polymerized lower alkyl acrylate and/or methacrylate having 1% to 20% free carboxyl groups, 2.5% to 10% polymethyl or polyethylmethacrylate, 5% to 10% water-soluable, thermosetting melamine resin, the balance being a volatile medium consisting essentially of water and a lower alkanol when deposited on a plastic film and cured at a temperature at least sufficient to volatilize the solvent, forms a transparent, abrasion-resistant coating.
