Title: Vacuum drums for printing, and duplex printers
Inventor: BUTLER KEITH PATRICK
IPC: B65H5/12
Filed: 1998-09-04
Granted: 2007-07-03
Abstract: A vacuum drum assembly for a printing machine comprises a drum having an array of passageways (40) distributed along its length and around its periphery to permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum, and an array of valve members (52), each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The arrangement is such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed. The open area of the drum is regulated such that it is small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the shape and size of the paper and the position of the paper on the drum, whilst minimizing the required suction flow. A duplex printing machine comprises two such vacuum drum assemblies with their drums parallel. The air pressure inside the drums is reduced and the drums are counter-rotated. Material to be printed on is fed to the first drum so that the material can be held on the first drum by vacuum and rotated therewith, and a first print head prints on one side of the material. The material is then released from the first drum in a direction towards the second drum so that the material can be held on the second drum by vacuum and rotated therewith. A second print head then prints on the material on the second drum. The material is then released from the second drum.

Title: External job scheduling with a distributed processing system having a local job control system
Inventor: SKOVIRA JOSEPH FRANCIS
IPC: G06F9/46
Filed: 2000-08-10
Granted: 2007-08-07
Abstract: External job scheduling capabilities are provided to a local job control system lacking or having insufficient job scheduling capabilities. This is accomplished by encapsulating running of a user job by the local job control system (LJCS) within running of a marker job at a node management system, which is responsive to an external resource scheduler. The technique includes starting a marker job by the resource scheduler external to the local job control system, wherein the marker job corresponds to a user job to be run by the LJCS; responsive to starting of the marker job, starting the user job by the LJCS; and upon termination of the user job, ending the marker job started by the resource scheduler, wherein starting of the user job by the LJCS is responsive to the resource scheduler's starting of the marker job and wherein ending of the marker job is responsive to termination of the user job.

Abstract: A clouding agent for dry beverage mixes is prepared by first forming a mixture of titanium dioxide and water and then subjecting the mixture to high speed shear. A spacing agent and suspending agent are then added to the mixture and the mixture is again subjected to a high speed shear, followed by spray drying. The resultant clouding agent may contain higher quantities of titanium dioxide than conventional clouding agents to thereby provide increased opacity without increased sedimentation. Further, the method of the invention provides higher throughput through the spray dryer and better yields than conventional methods of preparation.

Abstract: An artificial lift assembly is suspended from a string of conduit in a well inside a well casing. An encapsulation module is independently suspended from the conduit and encases the pump assembly with a jacket. A series of well fluid conditioning tools are mounted to the lower end of the jacket, including a tubular screen, a desander located behind the screen, a string of disposal conduit extending below the desander, and a nucleation device located above the desander. The entire weight of this fluid conditioning equipment is completely supported by the jacket and the conduit. The encapsulation module is completely sealed so that the well bore fluid is limited to entering the module and pump through the screen. The screen removes larger contaminants from the fluid such as rubber and trash.  After the fluid passes through the screen, it enters the desander where solid matter such as sediment is removed from the fluid and eliminated through the disposal conduit. Finally, the fluid enters the nucleation device where its scale is decomposed. After these three clarifying phases, the fluid enters the pump assembly and is pumped to the surface.
