  • Patent number: 4143975
    Abstract: An apparatus for applying adhesive to fibrous material in which a generally horizontal cylindrical member is provided having an inlet in the top near one end and an outlet in the bottom near the other end. A shaft is rotatable on the axis of the cylindrical member and has radially extending tools thereon angularly spaced from one another and disposed in a substantially helical path along the shaft. The tools nearest the inlet have a passage means therein through which adhesive is supplied to fibrous material introduced into the inlet while the others of the tools admix the adhesive with the fibrous material.

  • Patent number: 4117223
    Abstract: The present invention is related to a new process for producing cellulose C.sub.1 -C.sub.4 -alkyl ethers by subjecting cellulose to reaction with an alkali metal hydroxide and subjecting the resulting alkali metal salt of cellulose to reaction with an alkyl halide wherein the alkyl group contains 1 to 4 carbon atoms. The new process is characterized by subjecting 1 part by weight of cellulose to reaction with 0.5 to 4 parts by weight of the alkyl halide in a positive mixer having a fast-running mixing appliance and a container with adjustable internal pressure and cooling of the internal container wall, adding the alkali metal hydroxide in a concentrated aqueous solution or in a substantially water-free and finely divided state, and adjusting the pressure in the reaction vessel with cooling in such a way that the temperature of the reaction mixture remains in the range of from 15.degree. to 40.degree. C., and raising the temperature of the reaction mixture after termination of the alkalization to from 50.

  • Patent number: 4062646
    Abstract: Two-stage process for sterilizing loose material, such as flour, cocoa, feedstuffs, fillers for cosmetics and pharmaceuticals, and mould cultures, by means of sterilizing agents, such as superheated steam. In the first stage the loose material is vigorously mixed with the sterilizing agent by means of a mechanical agitator, while being brought to the sterilization temperature. In the second stage the loose material is allowed to remain virtually stationary for a predetermined length of time at the sterilization temperature.

  • Patent number: 4026686
    Abstract: A vacuum filter for separating solid particles from gaseous materials which contain or consist of condensible substances comprising at least one filter tube, through the walls of which the gaseous material flows, means for heating, substantially uniformly, the entire filter surface of the filter tubes by radiant heat, whereby the temperature of the gaseous material can be sustained above the dew point of the condensible substances in the region of the filter.

  • Patent number: 4015830
    Abstract: An apparatus for applying glue to chips, fibers and the like of wood, bagasse and other cellulose containing substances, which comprises a substantially cylindrical mixing chamber in which a shaft rotates equipped with radially extending mixing and/or glue applying tools. These tools immerse with their head region partly into a ring of chip material rotating at a relatively high speed. The glue applying tools comprises a glue conveying passage which in the lower region of the glue applying tools communicates with a glue feeding conduit associated with the driving shaft and in its upper region has a glue exit opening. The upper section of the glue applying tool has a glue discharge passage extending in a direction opposite to the direction of rotation of the glue applying tool. The end region of the glue discharge passage has at least one glue discharge opening.

  • Patent number: 4006706
    Abstract: A device for applying glue to chips, fibers or the like particles of cellulose containing substances, such as wood, bagasse, or the like, with an at least approximately cylindrical chamber in which the material to which the glue is to be applied passes through an inlet chute, an inlet zone, a gluing zone following the latter, a post-mixing zone, and an outlet in the form of a ring of material rotating along the cylindrical wall of the chamber, and in which on a shaft extending through the chamber, in the inlet zone there are arranged conveying tools which are provided with a vane or paddle-shaped working surface. Tools are arranged in the gluing zone and post-mixing zone for applying glue to and mixing the material.

  • Patent number: 3945616
    Abstract: A device for mixing glue or a like flowable substance with particulate material such as wood chips in which the chips are fed into one end of an elongated horizontal cylindrical chamber and are discharged from the other end while being caused to follow a rotary path in the chamber by a mixing member in the chamber having arms extending radially to near the periphery of the chamber. Glue feeding conduits extend into the chamber and into the ring of material therein between adjacent ones of said arms. The glue feeding conduits are connected in groups to manifolds and can be removed from the chamber in groups together with the respective manifold.
