Abstract: A system can perform a migration. The system can, in response to receiving a request to perform a file system operation on a destination file system, wherein the request identifies a first source file handle, direct, by a second computer and to a first computer, to perform the file system operation on a source file system with the first source file handle, to produce a second source file handle, convert the first and second source file handles to corresponding first and second components of a destination file handle, perform the file system operation on the destination file system with the first and second components of a destination file handle, respond to the client computer with the second source file handle. The system can re-assign a network address when rolling back the migration, wherein a client is configured to use the second source file handle with the source file system.

Abstract: A system can migrate a source file system on a first computer to a destination file system on a second computer. The system can receive, at the second computer, a request from a client computer that indicates a file system operation, and that references a source file handle of the source file system that comprises an identifier of the source file system. The system can identify the destination file system based on the identifier of the source file system. The system can determine, from a source inode number of the source file handle, a source inode number segment. The system can determine, from the source inode number segment, a destination inode number segment. The system can determine, from the destination inode number segment, a destination inode number. The system can perform the file system operation on the destination file system using the destination inode number and the identifier of the destination file system.

Abstract: A process for treating water is provided where the water is mixed with an inorganic reagent powder such as powder activated carbon. Organics and micropollutants are absorbed by the reagent powder. After the reagent powder has been mixed with the water, the water is directed to a setting tank and sludge from the water settles to produce a clarified effluent. Forming a part of the sludge is the reagent powder previously added. Sludge is collected and directed to a separator that separates the reagent powder from the sludge. Separated reagent powder is recycled and mixed with the water being treated.

Abstract: Disclosed is a method for the mounting, on an flexible substrate, of miniature electronic components of the beam lead type. Said method consists, after a first connection lead of a component has been soldered to the substrate, in arching each of the other connection leads of the component considered during their soldering by pressing the connection lead considered on a metallized zone of the substrate by means of a tip of a soldering tool while, at the same time, making a approaching movement towards the body of the component considered with this tip before carrying out the soldering operation itself. Through this mounting method, the beam lead electronic components are no longer placed flat against the substrate with their connection leads in an extended position but are arched on these leads. This gives them a freedom of play that enables them to absorb mechanical stresses by adopting positions of greater flatness or lesser flatness on the substrate.

Abstract: A symmetrical strip line type microwave circuit, the input-output connection zones of which are made in the following way:a groove is made in that of the insulating substrates which does not bear the central conductor of the symmetrical strip line circuit, along the contour of the desired connection zone;the two substrates are bonded together;the exterior of the structure is protected by electrolytic deposition of a tin-lead alloy;a counter-groove is made in the first substrate along the contour of the connection zone, and that portion of the substrate located inside the zone is eliminated.
