Abstract: ABSTRACT            CATALYST COMPOSITION FOR POLYMERIZING ALPHA OLEFINS      AND ALPHA OLEFINS POLYMERIZATION THEREWITH          A supported catalyst for polymerizing 1-olefins, for example, ethylene, is prepared by depositing a chromium compound and a titanium compound on a refractory oxide support which is substantially non-spherical, and which has a relatively broad particle size distribution range.  The catalyst is preferably combined, either outside of the polymerization vessel or in situ, with a sufficient amount of at least one magnesium composition of the formula RMgR', where R and R' are the same or different and they are C1 to C12 hydrocarbyl groups, to provide a molar ratio of magnesium to chromium in the catalyst composition of 0.01:1 to 25:1.  The resulting catalyst composition has good feedability and fluidization characteristics, and it produces resins of relatively high HLMI at relatively low temperatures.         There is also disclosed a process for polymerizing 1-olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the above-identified catalyst composition.  The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.

Abstract: ABSTRACT The system of the present invention uses the history and experience concerning the importance of an outage associated with a piece of equipment, the rate of damage caused by the continuing malfunction (the severity) and the confidence level in a malfunction diagnosis to determine the priority of repair of the piece of equipment by obtaining the product (46) of the confidence level (CF),importance (IMP) and severity (SEV). The confidence level, importance and severity are determined by rules of an expert system.  The severity is generally the reciprocal (88) of the time until the equipment fails.  The importance (44) is generally the cost to repair the maximum consequential damage when the malfunction is allowed to continue.  A malfunction can affect several pieces of equipment in combination, the severity and importance associated with each piece of equipment is combined (70) with the confidence level in the malfunction and used to determine the repair priority.  When the diagnosis of a malfunction is being performed by malfunctioning sensors, the expected life of the equipment (40) and the availability (86) of sensors that provide a partial backup to the malfunctioning sensors are considered in prioritizing sensor as well as monitored equipment repair.  When a primary piece of equipment is backed up (100), the effect of both pieces of equipment failing (106) is considered in prioritizing the repair.  The result is a system that ranks the repair of all possible malfunctions on a common scale even when disparate malfunctions are occurring.  The system gives a complete repair priority picture of a complex system and allows the cost effectiveness of the system being monitored to be maximized.

Title: Technique for fabricating complementary dielectrically isolated wafer
Inventor: EASTER WILLIAM G
IPC: H01L21/762
Filed: 1989-01-31
Granted: 1992-03-10
Abstract: Technique For Fabricating Complementary Dielectrically Isolated Wafer Abstract A method has been developed for providing tub regions with various resistivities in a dielectrically isolated (DI) structure. The starting substrate material is etched to expose the locations designated for a resistivity modification, and epitaxial material of the modified resistivity value is used to fill the exposed tubs. The remainder of the fabrication process follows conventional DI fabrication techniques. The procedure may simply be used to create a DI structure containingboth n-type and p-type tub regions. The idea may also be extended, however, to providing separate tubs with, for example, n+ resistivity, n- resistivity, p-resistivity and p+ resistivity, all within the same DI structure.

Abstract: A DATA PROCESSING SYSTEM HAVING A SHARED BUS AND       A PRIORITY DETERMINATION CIRCUIT THEREFOR                        Abstract In a data processing system, each bus master holds a priority code representing the bus use priority currently assigned to it.  The bus master outputs the code to a bus arbitration circuit when requesting the bus.  The bus arbitration circuit can be one that collectively performs the arbitration as a dedicated unit, or may be one that is distributed and held among the respective bus masters.  Each bus master has a highest priority register indicating the highest priority which it can possess, a lowest priority register indicating the lowest priority, and a request priority counter indicating the priority with which it is currently provided.  The counter is either incremented or decremented for each bus arbitration sequence.  In a situation in which the request priority in the counter approaches the highest priority by incrementing or decrementing, the request priority is compared with the lowest priority and, when the two are equal to the lowest priority in the lowest priority register is transferred to the counter.  Conversely, in a situation in which the request priority approaches the lowest priority, the request priority is compared with the lowest priority and, when the two are equal, the highest priority in the highest priority register is transferred to the counter.

Abstract: ABSTRACT: A signal generating circuit for ballast control of discharge lamps.     A ballast control apparatus for an electric discharge lamp (1) comprises a first series circuit including a first winding (5) of an Ac supply voltage transformer (4), a first winding (7) of a ballast transformer (8), a lamp current sensing resistor (11) and the lamp (1). A current sensing transformer (13) has a first winding (12) parallel to the resistor (11). A second winding (16, 9, 14) of the supply voltage transformer (4), the ballast transformer (8) and the current sensing transformer (13) are connected in a second series circuit. A signal voltage proportional to lamp power is derived by adding together the voltages included in the three series-connected second windings (9, 16, 14). A second signal voltage proportional to lamp voltage is derived across the series combination of the second windings (9, 16) of the ballast trans-former (8) and the supply voltage transformer (4). The voltage induced in the second winding (14) of the current sensing transformer (13) is proportional to lamp current. A signal voltage indicative of the condition of the lamp load can be derived across the second winding (9) of the ballast transformer (8). These three signal voltages are used to control a DC/AC inverter (2) that energizes the lamp (1) via the supply voltage transformer (4).           Fig. 1.

Abstract: ABSTRACT         Hot rolled strip or heavy plate is produced from stainless and refractory steels or from forgeable alloys on a nickel basis with a final thickness in the range of 5 to 60 mm by the production of a slab from monobloc casting or by continuous casting and heating the slab at a temperature above 1100°C, followed by the hot rolling of the slab and accelerated cooling of the product rolled to the end thickness.  The heated slab is rolled without interruption first to a maximum of 1/6 of its initial thickness, mainly by deformation passes in which the degree of deformation per pass is greater than that shown by curve A in Figure 1, in dependence on the surface temperature of the product.  Then finish rolling is performed to the end thickness, mainly by deformation passes in which the degree of deformation per pass is greater than that shown by curve B1 or curve B2 in Figure 1, in dependence on the surface temperature of the product and the pause between two adjacent passes as parameters.  The surface temperature of the finish rolled product must be not less than 1030°C, if the product contains up -to 1.0% molybdenum or not less than 1050°C, if the product contains more than 1.0% molybdenum.  At the latest 100 seconds following finish rolling, the product is cooled at an accelerated rate with a speed in the core of more than 3 K/sec, more particularly more than 5 K/sec, to a temperature which is equal to or lower than 650°C.
