Furthermore, the present invention relates to a supported metallocene catalyst using this metallocene compound and the olefin polymerization using the same. The metallocene compounds in this invention have superior characteristics in the preparation of supported catalyst due to the high reactivity with the support and minimal side reactions during the anchoring process. In addition, the olefin polymerization process employing the supported catalyst in this invention proceeds without fouling in the reactor, and the morphology and bulk density of the polymer produced are better than that produced by the conventional method.

Title: Terminal block with shoulder contact and formed ground plate retained by plastic insert
Inventor: JAY PETER ERVIN
IPC: H01R13/719
Filed: 2001-10-05
Granted: 2009-04-28
Abstract: A connector has a plastic housing (10) with a plurality of cavities or holes (13) for accepting "chips" (3), i.e., electrical elements such as transient suppression diodes, capacitors, metal oxide varisters, spark gap devices, and so on, connected between the a contact (20) and ground for RFI or EMI  suppression or the like. The contacts have shoulders with chip-contacting areas (23), preferably one surface of an annular flange (21). This allows numerous cavities to be arrayed around the axis of the contact (which can be radially symmetrical) so that numerous chips can be put in parallel between the contact and ground. In the case of capacitor chips, for example, this allows increasing the capacitance or varying the capacitance from one contact to the next. Grounding the ends of the chips opposite the contact shoulder is through a conductive spring, which can be a tine (43) bent from the inner periphery of an opening in a sheet-metal ground plate (40), or else can be a distinct item such as a piece of conductive elastomer (70). The ground plate is preferably fitted into the bottom of the housing along with a plastic retention insert which acts as a platform to supporting the tines and resist the force of the springs against the chips. The ground plate can be embodied as one or two ground strips running along either side of the connector. A  contact has compliant tines that are augmented with an internal coiled spring.  The contacts can be used (but are not limited in application) in a connector press fit into a PCB.
