摘要:
A method of providing access to the interior of a cross-line that intersects with a primary pipeline of equal or greater diameter, including the steps of attaching a branch fitting to the exterior of the primary pipeline on the side thereof opposite the point of intersection of the cross-line, affixing a full opening valve to the branch fitting, securing a hot tap machine to the valve, by use of the hot tap machine, cutting an opening in the primary pipeline diametrically opposite of the cross-line and of a diameter at least equal to the internal diameter of the cross-line, and removing the hot tap machine leaving an access through the valve and diametrically through the primary pipeline into the interior of the cross-line.

A method of providing access to the interior of a cross-line that intersects with a primary pipeline of equal or greater diameter includes the steps of attaching a branch fitting to the exterior of the primary pipeline, affixing a full opening valve to the branch fitting, securing a hot tap machine to the valve, using the hot tap machine to cut an opening in the primary pipeline of a diameter at least equal to the internal diameter of the cross-line, and removing the machine leaving an access diametrically through the valve and primary pipeline into the interior of the cross-line for installing pipeline inspection or cleaning pigs and/or a locking plug. A rotation resistor facilitates securing a locking plug within the pipeline.

A method of plugging a pipeline includes the steps of welding onto the exterior of the pipeline (10) first (12) and second (14) spaced apart collars, each having a sealing face (26,26A) in a plane perpendicular the pipeline (10) axis. A containment housing (34,36) is affixed by welding to the collars (12,14) to fully encompass a section of the pipeline (10) between the collars (12,14). A tapping (60) machine is then removably attached to an open top of the containment housing (34). Using the tapping machine (60) a short length of the pipeline (10) is cut and removed from between the collars (12,14) leaving two open exposed pipe ends (78,80). First and second seal elements (92,94) are positioned between the collars (12,14), Each having a forward sealing face. The seal elements (92,94) are forced apart from each other into sealing engagement with the collar sealing faces thereby closing the open, exposed ends (78,80) of the pipe (10).
摘要:
A steam-based document storage and retrieval system accepts documents that are in diverse formats and come from diverse application, automatically creates document model objects describing these documents in a consistent format and associating time stamps with the documents to automatically create a main stream in chronological order. The stream, or sub-streams meeting selected search criteria, are displayed in a variety of forms, including a receding, partly overlapping stack with aids that facilitate user interaction.

Media content, based on a predetermined set of constraints, from a content provider is delivered to a local cache of a user device before viewing the media. A client asset manager process resides in the user device, an asset list at the content provider site, and the media assets are located at a remote site.

摘要:
The invention relates to bit patterned recording media having a stop layer for chemical mechanical polishing. One embodiment of the present invention is a method of manufacturing a magnetic recording medium comprising the step of planarizing by chemical mechanical polishing until the stop layer is reached. The present invention also provides a magnetic recording medium having a stop layer.
摘要:
A method for defining patterns in an integrated circuit comprises defining a plurality of features in a first photoresist layer using photolithography over a first region of a substrate. The method further comprises using pitch multiplication to produce at least two features in a lower masking layer for each feature in the photoresist layer. The features in the lower masking layer include looped ends. The method further comprises covering with a second photoresist layer a second region of the substrate including the looped ends in the lower masking layer. The method further comprises etching a pattern of trenches in the substrate through the features in the lower masking layer without etching in the second region. The trenches have a trench width.
摘要:
A document stream operating system and method is disclosed in which: (1) documents are stored in one or more chronologically ordered streams; (2) the location and nature of file storage is transparent to the user; (3) information is organized as needed instead of at the time the document is created; (4) sophisticated logic is provided for summarizing a large group of related documents at the time a user wants a concise overview; and (5) archiving is automatic. The documents can include text, pictures, animations, software programs or any other type of data.
