摘要： A method for controlling the density distribution of bulk material in the manufacture of pressed wood panels includes the step of eliminating the irregularities in the bulk material stream as it flows to the forming station. Apparatus for accomplishing this result includes a pair of spaced apart parallel rollers that define an adjustable slotted opening through which the material passes. Rotation and oscillation of the rollers function to render uniform the density distribution of the bulk material stream.

摘要： This invention relates to a reactor 1 for the continuous production of linear or cyclic acetals, in particular trioxane, dioxolane, tetroxane, dimethoxymethane, diethoxymethane, diethoxyethane and dibutoxyethane. This reactor has internal adjacently arranged evaporator elements 2, which allow for flow-through of a heat transport medium, and which are at least two meters high so as to generate a thermosiphon flow. The clear cross section between the evaporator elements is 20 to 80% of the overall cross section. Using the reactor, circulation ratios of up to 250 can be achieved. Thus, the reliability and availability of a production plant is increased while the susceptibility to breakdown decreases.

摘要： Method and apparatus are provided for equalizing the density distribution of pressed wood panels manufactured from adhesive coated bulk material. A bottom belt hopper has an outlet, the width of which is identical with the spreading width for the pressed wood panels being manufactured. Devices installed below the bottom belt hopper transport the bulk material as adhesive coated chip material onto a forming belt. Density deviations existing in the bulk material when it is removed from the bottom belt hopper are determined and correspondingly eliminated. If required, a density profile for a finished pressed wood panel is provided when the bulk material is taken from the bottom belt hopper.

摘要： An adjustable volume vane-type rotary pump is disclosed in which volume control is obtained by adjusting the eccentricity of a control ring against which the vanes run. The control ring is urged towards its position of maximum eccentricity by a spring and position control of the ring is obtained by a piston and cylinder system operating in opposition to the spring. Operation of the piston and cylinder assembly is dependent on the dynamic pressure of fluid delivered by the pump so that when a certain speed of rotation is achieved the pressure exerted by the piston and cylinder system will be sufficient to overcome the force of the spring and adjust the position of the control ring.

摘要： The present apparatus deposits a fleece of wood chips, particles or shavings on a conveyor belt for manufacturing panels. In order to avoid a uniform orientation of all particles in one direction and to assure an orientation of the particles in all directions in substantially uniform distribution, there is provided a particle flow disturbing device for disorienting the chips, particles or shavings as they are directed toward a conveyor belt. The particle flow disturbing device includes a plurality of screens, which intersect at a common axis, which is located slightly above and across the conveyor belt and which extends normal to the direction of movement of the conveyor belt. The wood chips are directed downwardly through the screens by an air current flowing generally in parallel to the conveyor belt to mix the descending wood chips. The common intersection axis of the screens is located upstream of the opposite edges of the screens with respect to the air current. The lowermost screen extends in parallel to the belt and the opening angles between adjacent screens is preferably the same.
