Abstract: The present invention relates to a process of producing an ethylene polymer composition in multiple stages of which the first stage is a slurry polymerization stage, in the presence of a catalyst system comprising a) a solid catalyst precursor comprising a transition metal selected from titanium and vanadium; magnesium, a halide, optionally an electron donor, and a solid particulate material comprising an inorganic oxide, wherein the median particle diameter of the solid catalyst precursor based upon the total volume of solid catalyst precursor, D50, is from 1 to 13 micrometers; and b) an organoaluminium compound.

Abstract: A compression ignition internal combustion engine which operates using a methane based fuel and an ignition initiator. The fuel and method of operating the engine can be employed in a range of applications such as, for example, road or marine vehicles or in static applications such as electrical generators.

Abstract: The present invention provides a tampon applicator assembly having an applicator barrel with an insertion tip with a maximum of three petals. Additionally, the tampon applicator assembly can be provided with a tapered insertion tip. A shaped pledget can be housed in the applicator barrel, which provides support to the petals.

Abstract: A bypass blade is pivotably connected to the first terminal pad, and movable between open and closed positions. The bypass blade is electrically connected between the first and third terminal pads when in the closed position. A first disconnect blade is pivotally connected to a second terminal pad and movable between open and closed positions. The first disconnect blade is electrically connected between the first and second terminal pads when in the closed position. A second disconnect blade is pivotally connected to a fourth terminal pad and movable between open and closed positions. The second disconnect blade is electrically connected between the third and fourth terminal pads when in the closed position. An interrupter lever is connected to an interrupter and electrically connected to the third terminal pad. A hook ring is connected to the first and second disconnect blades. The hook ring is movable between closed and open positions.

Abstract: A process for polymerizing polyethylene with chromium-based catalysts wherein one or more supported chromium-based catalysts is mixed with mineral oil to form a slurry and the slurry is then introduced into a polymerization reactor, especially a gas-phase polymerization reactor.

Abstract: A connector for an electrical box having a base that has an opening. A cavity is formed by a wall extending from the base. The cavity is aligned with the opening to form a passageway through the connector to receive electrical cable. At least two fingers extend inwardly and toward the base from an inner surface of the wall. At least two tabs extend outwardly and toward the base from an outer surface of the wall to retain the junction box between the at least two tabs and the base.

Abstract: Polyethylene resins having improved environmental stress crack resistance, stiffness and impact resistance is made by a process comprising feeding both a chromium oxide catalyst and a silyl chromium catalyst into a polymerization reactor. The chromium oxide catalyst and the silyl chromium catalyst are on separate supports. The chromium oxide catalyst is 25-50 weight percent and the silyl chromium catalyst is 50-75 weight percent of the total weight of catalyst. The catalysts may be added separately or as a single mixture.

Abstract: An electrical box bracket has an adjustable member to facilitate securing the bracket to supports of varying sizes. The bracket has first and second legs that are connected by a third leg. A cut-out extends from the first leg onto the third leg. The adjustable member is formed by the cut-out to facilitate securing the bracket to the support. A centerline on the third leg of the bracket is adapted to be aligned with corresponding indicia on the support. The support indicia is visible through the cut-out to facilitate positioning the bracket on the support. A plurality of weld projections on the second leg facilitate securing a variety of different electrical boxes to the electrical box bracket.

Abstract: The invention provides for polymerization catalyst compositions, and for methods for introducing the catalyst compositions into a polymerization reactor. More particularly, the method combines a catalyst component containing slurry and a catalyst component containing solution to form the completed catalyst composition for introduction into the polymerization reactor. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom.

Abstract: An electronically controlled lube oil and fuel blending system is provided which controls the amount of lube oil delivered from an engine lube oil supply system to an engine fuel supply system based on the amount of fuel added to the fuel supply system thereby maintaining a constant lube oil/fuel ratio or lube oil concentration in the fuel supply system 16 regardless of variations in engine operation thereby minimizing emissions, such as particulate matter. The system includes a lube oil injection circuit connecting the engine lube oil supply system to the fuel supply system and an emission compliance lube oil concentration control system for controlling a lube oil concentration in the fuel supply system to maintain compliant engine emissions during engine operation.

Abstract: A collapsible table, particularly a book-simulating collapsible table, comprises a central support component having hinged to its opposite sides a pair of leaves which in their extended position form a table top and in their collapsed condition form a container, for example a container of small compass resembling a book in its external appearance. A plurality of legs is pivotally connected to the support member. In the collapsed condition of the leaves, the legs are contained in collapsed condition within the container. In the extended, or table top, condition of the leaves, the legs are extended to perform their usual support function.

Abstract: A gas turbine combustor arrangement involves two combustion chambers separated by a necked down throat portion with provision for fuel introduction into each of the chambers. Initially, fuel is introduced into the first chamber and ignited. Thereafter, fuel is introduced into the second chamber until the total fuel flow to the combustor is at the desired rate. Burning in the first chamber is then extinguished by shifting fuel flow to the second chamber and after burning termination, the fuel distribution is reversed until a low emission operation is realized. Apparatus for carrying out the foregoing method and a high load ingition system is also disclosed.

Abstract: A traffic responsive control system for controlling one-way traffic through a door in which the door opening means is disabled when power is initially applied to the control system while permitting the door opening means to respond to a door opening signal on the traffic side of the door immediately after termination of a safety signal on the safety side of the door.
