Abstract: Embodiments are directed towards a use of a supported biphenylphenol polymerization catalyst to make a polymer via a slurry-phase polymerization process, where the supported biphenylphenol polymerization catalyst is made from a biphenylphenol polymerization precatalyst of Formula I.

Abstract: A roof for use with an outdoor cooking appliance includes a A primary support assembly including a base and at least one support post, the base being coupled to the support post. A roof assembly includes a plurality of roof panels coupled to the at least one support post such that each is supported above the base. The roof panels are oriented such that the rear edge of one roof panel and the front edge of the adjacent roof panel overlap in at least a horizontal direction but are spaced apart to define an airflow passage therebetween. An outdoor cooking installation can be formed by mounting the roof over an outdoor cooking appliance.

Abstract: An apparatus for analyzing a golf swing or other biomechanical movement includes first and second rectangular force plate mounted within a respective first and second rigid rectangular frame by means of at least one load cell proximate each corner of each rectangular force plate. The second rigid rectangular frame being secured to the first rigid rectangular frame so as to prevent relative lateral movement therebetween, and each of the load cells is operably connected to one or more microprocessor devices for receiving a signal generated by each of the load cells indicative of a force applied thereto.

Abstract: A cylindrical tank (12) is formed from stainless steel plates. Proximate an open top end (17) of the tank (12) are four evenly spaced mixing assemblies (20). An intake pipe (22) is positioned with an open end (38) below the surface of a biological conversion medium (16) to allow a pump (28) to draw the medium (16) into a receiving box (24). A downcomer (26) merges with the receiving box (24) in order to allow the medium (16) to be injected with a biological conversion component such as air through an inlet pipe (34). The medium (16) and the injected component then pass through a static in-line mixer (30) which thoroughly mixes the medium (16) with the component and creates a multitude of finely-divided air bubbles for circulation and feeding of the medium (16) throughout the tank (12).

Abstract: A process for the biological oxidation of sulfide in sulfide-containing ore. Preferably, the ore is then subjected to cyanide leaching. The resulting leach tail solution can be subjected to cyanide precipitation, employing ferric sulfate which is generated during the biological oxidation step of the process. Furthermore, a process for efficiently aerating the ore slurry during the biological oxidation step is provided.

Abstract: Minerals, which when mined are recovered in plate-shaped form, such as vermiculite, are efficiently concentrated in a process wherein the mined ore is passed over a series of revolving spaced rolls. Various preferred aspects of the process such as the use of rubber covered rolls, rolls having different spacing therebetween, etc., are also described.
