Abstract: Starch(es) and starch derivatives are combined together with at least one high-viscosity cellulose as a thickener in dispersion binder-based color systems. The cellulose has a viscosity of >50,000 mPa·s, measured by the Brookfield rotation viscometer as a 2% swollen aqueous solution at 5 rpm and 25° C. A method produces dispersion binder-based color systems and a dispersion color thickener combination and a dispersion color containing the dispersion color thickener combination.

Abstract: A toolholder for use in a rotary crop-cutting machine, such as a mowing or chopping machine, comprises a rotatable tool carrier, to which the tools are adapted to be pivoted on pins, which are parallel to the axis of rotation of the tool carrier. Each of said pins carries at least one tool and at opposite ends is radially slidably mounted in axially aligned slots, which extend radially with respect to the axis of rotation and are formed in two axially spaced apart lugs, which are secured to and substantially radially protrude from the body of the tool carrier, or in two axially spaced apart disks, which constitute the tool carrier. Each of said slots has a radially outer portion for retaining the associated pin against axial displacement in said radially outer portion.

Abstract: A machine for cutting vegetable material, such as a mowing or chopping machine, comprises at least one rotatable tool carrier and tools pivotally mounted on said tool carrier by pins which are parallel to the axis of rotation of the tool carrier. In order to provide a machine which has a robust structure and facilitates the mounting and removal of the tools, each pin carries at least one tool and at opposite ends is movably mounted in two slots, which extend radially with respect to the axis of the rotation of the tool carrier and are formed either in two opposite disks, which constitute the tool carrier, or in lugs, which are secured to and radially protrude from the body of the tool carrier. Each slot has a radially outer portion provided on the outside with a cover for preventing an axial displacement of the associated pin.

Abstract: The mowing and chopping machine comprises at least two rotors, which are rotatable about vertical axes, which are spaced apart transversely to the direction of travel of the machine. Each rotor comprises a tooth-carrying disc and a plurality of cutting rotor teeth, which are angularly spaced apart and pivoted to said disc by means of vertical pins and protrude from the periphery of said disc. The rotor teeth are either curved upwardly and downwardly out of the plane of the disc or are composed of a plurality of superimposed cutter blades. A fixed backing cutter is provided in the generally triangular space defined by the flight paths described by the rotor teeth.
