Abstract: A circuit is set up for a container or vessel (10) as shown in FIG. 1, which has a microphone (20), a speaker (30), a frequency control device (40) volume control device (50), an amplifier (60), a frequency reader (70) and a spectrum analyzer (80). The oscillation in the circuit is created by applying power to the amplifier (60) which creates an initial fixed standing wave that does not move. Adjusting or changing components, invokes a new behavior of the circuit which is parasitic in nature and reading of oscillating frequency on the frequency reader (70) determines the change of conditions inside the vessel or container. The method is non-intrusive, and the method of this invention can also be used for measurement of miniscule quantities in microns or micro liters such as that of biofilm or algal growth.

Abstract: The present invention relates to catalyst supports and improvements thereof for use with supported activators and supported transition metal catalyst systems. The invention specifically involves reacting a carrier containing reactive functionalities, e.g., hydroxyl containing silica, with halogenated organic compounds, e.g., fluorosubstituted phenols. The reaction is preferably carried out in the presence of a base. The reaction consumes undesired functionalities on the support to provide a halogenated support which is suitable for activators and catalytic precursors which are adversely affected by functionalities typically found on supports. The supported activators or catalytic precursors are prepared by contacting the precursors or activators with the halogenated support.

Abstract: In accordance with this invention are methods for making the novel compositions and methods of using the compositions for polymerization of olefins. In its broadest form, the method of producing the supported catalytic composition of the present invention comprises treating an inorganic or inorganic oxide support which has incorporated uniformly therein a Group 3-10 transition metal from the Periodic Table with a metal alkylating reagent wherein the reaction product is then treated with a halogenating reagent. The resultant reaction product can be recovered and is available for use in conjunction with the activating co-catalyst for the polymerization of polyolefins.
