Abstract: Device for laser surveying of an environment A device for surveying an environment by time-of-flight measurement of laser beams reflected therefrom comprises a beam deflection device having at least one mirror surface which can be rotated or oscillated about an axis of rotation which is non-normal to the mirror surface. The device further comprises a first laser transmitter with associated first laser receiver, and a second laser transmitter with associated second laser receiver. The transmission and reception directions of the first and second laser transmitters and receivers lie parallel to one another in pairs and at different angles to the axis of rotation. The first laser receiver is spaced apart from the first laser transmitter and the second laser receiver is spaced apart from the second laser transmitter, in each case in the direction of the axis of rotation.

Abstract: The invention relates to a process for preparing partial hydrolysates of organometallic compounds and to a process for preparing partial hydrolysates of organometallic compounds, in particular alkylaluminoxanes, or transition metal catalysts immobilized on inert support materials and also to the products prepared by this process.

Abstract: Disclosed is a process for preparing a supported metallocene catalyst by introducing, in a first stage, a gas stream comprising an organoaluminum compound, an inert support material and water, into a first gas phase reactor; allowing the mixture to react under conditions effective to form an aluminoxane supported on said inert support material; metering a second gas stream comprising a metallocene into said gas phase reactor; allowing said mixture to react under conditions effective to form a supported metallocene catalyst; and drying, in a second stage, said supported metallocene catalyst, wherein said drying is carried out in a gas phase reactor.

Abstract: The present invention is directed to a gas phase process of preparing a supported metallocene catalyst wherein an alkylaluminum compound, water, a metallocene and, optionally, an olefin are metered into a fluidized bed reactor containing a fluidized bed of an inert support material in the presence of a gas stream.

Abstract: Disclosed are homogeneous formulations consisting essentially of one or more oxidation-sensitive organometallic compounds in a hydrocarbon, such as paraffins having a boiling point of at least 150.degree. C. and a viscosity of at least 1 Pa.s at 25.degree. C. Also disclosed is a process for the preparation of these formulations.
