Title: Process for preparing polyolefin products
Inventor: BAXTER C EDWARD JR
IPC: C08F110/10
Filed: 2000-09-08
Granted: 2012-05-01
Abstract: A novel liquid phase polymerization process for preparing a polyolefin product having preselected properties is disclosed. The process includes the steps of providing a liquid feedstock which contains an olefinic component and a catalyst composition consisting of a stable complex of BF3 and a complexing agent therefor. The feedstock may comprise any one or more of a number of olefins including branched olefins such as isobutylene, C3 to C15 linear alpha olefins and C4 to C15 reactive non-alphaolefins. The feedstock and the catalyst composition are introduced into a residual reaction mixture recirculating in a loop reactor reaction zone provided in the tube side of a shell and tube heat exchanger at a recirculation rate sufficient to cause intimate intermixing of the residual reaction mixture, the added feedstock and the added catalyst composition. The heat of the polymerization reaction is removed from the recirculating intimately intermixed reaction admixture at a rate calculated to provide a substantially constant reaction temperature therein while the same is recirculating in said reaction zone. The conditions in the reactor are appropriate for causing olefinic components introduced in said feedstock to undergo polymerization to form the desired polyolefin product in the presence of the catalyst composition. A product stream containing the desired polyolefin product is withdrawn from the reaction zone.  The introduction of the feedstock into the reaction zone and the withdrawal of the product stream from the reaction zone are controlled such that the residence time of the olefinic components undergoing polymerization in the reaction zone is appropiate for production of the desired polyolefin product.

Abstract: Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or video tape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces. Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying.

The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together. The cylindrical member can be bent along multiple axes. The occipital plate secures the rods to the occipital bone of the skull. The occipital plate has a cross-shaped plate with a plurality of apertures defined in the plate and at least one saddle member coupled to the plate. Alternatively, the occipital rod can be secured to the occipital bone.

Abstract: A method of controlling a gas distribution system (1) in which one or more air separation plants (18, 20) supply gaseous oxygen and nitrogen products to pipeline sections (10, 12). The air separation plants (18, 20) are controlled by supervisory control systems (30, 32) that direct production rates of the gaseous products to be consumed by customers (14, 16) connected to the pipeline sections (10, 12). The gas distribution system (1) is controlled by a model predictive control system (34) in which empirically determined open loop response models are used to generate open loop responses of the pipeline sections (10, 12) due to changes in customer demands. Optimized closed loop responses in production rate requests to the supervisory control systems (30, 32) are generated by model predictive control techniques.
