Abstract: A method of preparing particles of a lignocellulosic material for the manufacture of a finished product, such as a particle board, includes the steps of chemically modifying the lignocellulosic material by impregnating the lignocellulosic material with a suitable anhydride in a non-aqueous solvent; applying to the particles of lignocellulosic material an adhesion promoter to promote the adherence of a thermoplastic resin to the surfaces of the particles of lignocellulosic material; and applying to the particles a thermoplastic resin in dry powder form, so that after the application of the adhesion promoter, the thermoplastic resin adheres to the surfaces of the particles of lignocellulosic material, the thermoplastic resin having been surfaced modified by irradiation or by fluorination; and removing any solvent present.

Abstract: The invention relates to a method of producing seals and coatings, and of bonding tiles and floor coverings, in which aqueous dispersions containing at least 20% by weight of filler and comprising a polymer mixture of a) an acrylate polymer A having a K value of from 5 to 55 and a glass transition temperature of below −10° C. and b) an acrylate copolymer having a glass transition temperature of from −50 to +50° C., are applied as sealants, coating materials or single-side adhesives. The compositions which are used, based on the filler-containing dispersions of the polymer mixture, are notable in processing for improved fixing in the wet and dry state, high heat stability, good adhesion to rubber and, since they are essentially free from organic solvents, plasticizers and resins, by a high level of environment-friendliness.

Abstract: A novel method for joining aluminum nitride-series substrates to each other is provided in the substantial absence of an intervening third layer at the joining interface between the substrates. In the method, the aluminum nitride-series substrates are joined to each other by interposing a joining agent between the substrates heating the substrates and the joining agent to a first temperature range of at least the melting point of the joining agent to melt the joining agent and liquefy particles of the aluminum nitride at the neighborhood of the interfaces between the melted joining agent and the substrates, and then heating the joining agent and the substrates to a temperature range higher than the temperature range of the first process but lower than the melting point of the substrates to exhaust the joining agent from between the substrates.

Abstract: The present invention is related to a method of preserving plywood, particle board and similar wood composite products made from wood pieces/particles and a binder used to adhere such wood pieces/particle together against rot and mould decay. According to the invention, the preservative of the wood material is a complexing agent which is capable of binding transition group metals and is admixed into the binder used in the manufacture of said wood composite products prior to the formation of said product. The invention also concerns a binder composition, which contains a polymer resin as its adhesive component and a complexing agent, particularly an aminotetracarboxylic acid or a salt thereof, by approx. 1-30 wt.-% as the preservative of the wood material, and a method of producing said binder composition. Tests performed on faced plywood indicated that a water-soluble, environmentally safe complexing agent offers a white rot resistance which is superior to conventional preservatives commonly used today.

Abstract: A vehicle (e.g., a truck) rubber air spring is bonded to a seat of a fixturing sleeve. A bead of the air spring has a rubber primer thereon and the seat of the fixturing sleeve has a fixturing primer thereon. An adhesive located between the rubber and fixturing primers permanently secures the air spring to the sleeve seat.

Abstract: An improved feed block is produced by a novel process in which a fluid mixture comprising molasses, additives and other nutrients is produced into a dehydration vessel operating under a partial vacuum. The fluid mixture is heated to a temperature less than about 130° F. and agitated within the dehydration vessel to drive water from the fluid mixture. The water vapor is cooled, condensed and removed from the dehydration vessel to a condensate collector where the amount of water removed can be measured to determine the degree of dehydration. Once an appropriate amount of water has been removed, the dehydrated fluid mixture is produced from the dehydration vessel, formed into block shapes and cooled to form feed blocks. The resulting feed blocks are high in nutritional value because the low temperature dehydration process prevents the nutrients from being thermally destroyed.

Abstract: Curved surfaces of a preform of thermoplastic adhesive provide improved regulation of heating and exclusion of gas as surfaces to be bonded are heated and pressed against the thermoplastic adhesive preform. Particulate or filamentary materials can be added to the thermoplastic adhesive for adjustment of coefficient of thermal expansion or further increase of heat transfer through the adhesive or both. The preform is preferably fabricated by molding, preferably in combination with die-cutting of a preform of desired volume from a web of approximately the same thickness as the completed bond.
