    摘要: Improved Ziegler-Natta catalysts and methods of making the improved catalyst are described. The Ziegler-Natta catalyst is formed using a spherical MgCl2-xROH support, where R is a linear, cyclic or branched hydrocarbon unit with 1-10 carbon atoms and where ROH is an alcohol or a mixture of at least two different alcohols and where x has a range of about 1.5 to 6.0, preferably about 2.5 to 4, more preferably about 2.9 to 3.4, and even more preferably 2.95 to 3.35. The Ziegler-Natta catalyst includes a Group 4-8 transition metal and an internal donor comprising a diether compound. The catalyst has improved activity in olefin polymerization reactions as well as good stereoregularity and hydrogen sensitivity, and may be useful in the production of phthalate-free propylene polymers having a molecular weight distribution (PI(GPC)) in the range from about 5.75 to about 9.

    摘要: A rotating laser device and method is disclosed. The laser device includes a laser unit, which generates a laser beam, a leveling device, which aligns the laser beam in a horizontal plane which is arranged perpendicular to the gravitational field of the earth, an inclination device, which inclines the laser beam about an axis of inclination in relation to the horizontal plane, a rotational unit which moves the laser unit at least partially about an axis of rotation at a rotational speed, and a measuring unit with which an angle of rotation of the laser unit about the axis of rotation can be determined such that a memory unit is provided for storing at least one angular position.

    摘要: A laser receiver (1) for acoustically indicating a laser beam, including a housing (4), a detector unit (6) that ascertains the actual position (2) of the laser beam, an evaluation unit (8) that determines the difference between the actual position (2) and the target position (3), and an acoustic indication device (7) that uses an acoustic signal to indicate whether the actual position (2) of the laser beam is above, below or at the target position (3), wherein a control unit (9) is provided that, as a function of the difference between the actual position (2) and the target position (3), generates a scanning signal to modulate a basic signal, and then sends the scanning signal to the acoustic indication device (7).
