    摘要: This invention provides a method of reducing the sulfur oxide emissions from the regenerator of an FCC process that cracks a sulfur containing feedstream. The sulfur oxide emissions are reduced by using an essentially sulfur free lift gas stream to shift the sulfur concentration equilibrium between the product stream from the reaction zone and the flue gas stream from the regeneration zone. Sulfur compounds present in the FCC feed leave the reaction zone as volatile sulfurous gases in the product vapor stream or as adsorbed sulfur compounds on the catalyst. Sulfurous gas in the product vapors is mainly H.sub.2 S. By lowering the concentration of H.sub.2 S that enters the riser with the lift gas the equilibrium reaction of sulfur with hydrogen in the riser is favorably shifted to increase the production of H.sub.2 S and decrease the lay down of sulfur compounds in the coke that forms on the catalyst. As a result less sulfur enters the regeneration zone with the spent catalyst and fewer sulfur oxides are formed during regeneration.

    摘要: A pump has an elongated shell with a generally elliptical shape, an outer convex surface and an inner concave surface. A peripheral side edge located between the inner and outer surfaces terminates in a bead edge. A flexible airtight membrane has a membrane edge bonded to the outer shell surface adjacent to the bead edge. Preforming the membrane edge looped with a maximum linear span of curvature that is greater than a maximal transverse linear extent of the bead edge, membrane operational wear during inflation and deflation cycles is reduced in the region around the bead edge. A process of forming a blood pump with a membrane preform is also provided.

    摘要: A high throughput sputtering apparatus which provides a single or multi-layer coating to the surface of a plurality of substrates. The apparatus comprises a plurality of buffer and sputtering chambers which include an input end and an output end. The substrates are transported through the chambers at varying rates of speed such that the rate of speed of a pallet from the input end to the output end is a constant for each of the pallets. The high throughput sputtering apparatus also includes a transport system which transports the substrates through the sputtering chambers at variable velocities, a high capacity vacuum pump system which evacuates the ambient pressure within the sputtering chambers to a vacuum level within a pressure range sufficient to enable sputtering operation, a substrate heating system which heats the substrates to a temperature conducive to sputtering the coatings thereon and provides a substantially uniform temperature profile over the surface of the substrates; and an electronic control system which provides control signals to and for receiving feedback input from other components of the apparatus. The electronic control system is programmable to control the sputtering chambers, the transport system, the vacuum pump system, and the substrate heating system. The substrate heating system efficiently maintains a desired substrate temperature by minimizing radiative heat losses as the substrates proceed through the sputtering apparatus. The high throughput sputtering apparatus provides substrates to be sputtered in a rapid and uniform heating process to optimize film integrity during the sputtering steps, provides successive layers of thin films on the substrates, and removes the sputtered substrates without contaminating the environment.

    摘要: An improved method and system is described for generalized handling of conditions occurring during program execution in a computer system having a multi-language Condition Manager (CM). A general signaling routine having object code for an external entry point suitable for linking to application programs written in any language supporting external calls is used. The signaling routine may be used by programs to eliminate the step of checking return codes from subroutines by coding the subroutine to automatically signal the proper condition to the CM which in conjunction with user defined condition handlers takes proper actions in response to the condition. A general condition token which may be used as a feedback token is defined as a condition identifier, a format code for the condition identifier, a severity code for the condition, a control code for a facility identifier, a facility identifier and an optional handle for instance specific information. The signaling routine and the feedback token are used by subroutines which can optionally provide for passing an address, where a feedback token can be stored. The subroutine signals conditions if the severity of the condition is greater than a threshold or else stores a feedback token at the address.

    摘要: A hand vacuum cleaner is provided comprising a lightweight motor housing containing a revolving brush. A bag assembly is selectively separable from the housing and is sealable to the housing with an elastomeric retaining ring including a sealing and retaining bead for reception in a recessed slot area of a housing bag attachment collar. A fan is mounted to the motor on a motor shaft locking surface including a wall portion tapering towards the fan. The shaft is in locking cooperation with a mating fan bore locking surface including a wall portion tapered for close reception of the motor shaft locking surface. A shaft extension is threadedly received on the motor shaft and is urged into engagement against the fan by resistance of a revolving brush operated by a belt received on the shaft extension which continually tightens the shaft extension to the motor shaft and fixes the fan to the motor shaft. A stone shield is circumferentially spaced about the fan whereby the stone shield blocks items impinging against the housing from the fan from damaging the housing. The housing further includes an air deflector substantially received in the bag assembly having a terminal end portion disposed radially inwardly from the housing outer wall whereby the deflector directs the working air to facilitae greater storage of vacuumed dirt in the bag and prevent heavy objects received in the bag from rolling back into the housing and contacting the fan. A nozzle guard is mounted on a housing nozzle including brush bearing housing retaining elements disposed for a deflecting interference fit to the bearing housings whereby the brush is positively retained in the nozzle to minimize vibrational movement.
