Abstract: The invention concerns a power take-off apparatus for a tractor. The power take-off apparatus comprises a power take-off (PTO) shaft (1) on which have been disposed two gear wheels (4,5) arranged to be freely rotatable and which operate independent of the speed of rotation of the tractor's traction wheels. The first gear wheel (4) has been arranged to rotate within a high speed range and the second gear wheel (5), within a low speed range. The PTO apparatus furthermore comprises two shaft pins (2,3) alternatively attachable to the PTO shaft (1), of which the first shaft pin (2) is intended for the high speed range and the second shaft pin (3), for the low speed range. When said second shaft pin (3) is attached to the PTO shaft (1), the shift sleeve (12) can be optionally coupled with said second gear wheel (5), but it is prevented from becoming coupled with said first gear wheel (4). When said first shaft pin (2) is connected to the PTO shaft (1), the shift sleeve (12) can be optionally coupled with the first or second gear wheel (4 or 5). On the PTO shaft (1) has furthermore been disposed a third gear wheel (25) arranged to be freely rotatable and arranged to operate at a speed dependent on the speed of rotation of the tractor's traction wheels. The shift sleeve (12) can be optionally coupled with said third gear wheel (25) independent of which one of the shaft pins (2 or 3) has been attached to the PTO shaft (1).

Abstract: A catalyst is prepared by combining a first compound consisting of a bis(cyclopentadienyl)zirconium compound having one of the following general formulae:Wherein:(A-Cp) is either (Cp)(Cp*) or Cp-A'-Cp* and Cp and Cp* are the same or different substituted or unsubstituted cyclopentadienyl radicals;A' is a covalent bridging group;L is an olefin, diolefin or aryne ligand;Zr is zirconium;X<sub>1</sub> and X<sub>2</sub> are, independently, selected from the group consisting of hydride radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like;X'<sub>1</sub> and X'<sub>2</sub> are joined and bound to the zirconium atom to form a metallacycle, in which the zirconium, X'<sub>1</sub> and X'<sub>2</sub> form a hydrocarbocyclic ring containing from about 3 to about 20 carbon atoms; andR is a substituent on one of the cyclopentadienyl radicals which is also bound to the zirconium atom. With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.

Abstract: A process for determining the thickness and/or change in thickness of a thin layer applied to a carrier, with the carrier coated with the thin layer being radiated with a plane polarized light beam and the reflectance on carrier and layer being detected. The light reflected by the carrier and the thin layer is split into a p-polarized part and an s-polarized part, after which the respective reflection values Rp and Rs are measured simultaneously for the two parts, and the quantity <MATH> is determined, in which formula m is a variable parameter and the quantity M is a function of the thickness of the thin layer. By measuring both the reflection of p-polarized radiation and that of s-polarized radiation, and by adroitly combining the measuring data obtained, the resulting signal will be insensitive to the intensity of the radiation source. An additional advantage is that the process has a greater sensitivity to variations in layer thickness, and that it is possible for the process to be carried out within a wide linear measuring range. In determining the growth of a protein layer the measuring result is independent -within wide limits- of the thickness and the index of refraction of a layer previously applied to the carrier.
