Abstract: A system and method for providing improved water line installation, and more specifically, to a system and method for providing a positive stop flow pipe isolation insert for use in installing water lines to an existing and active main water line is disclosed. The positive stop flow pipe isolation insert includes a water system pipe isolation insert segment connected to mechanical gate valve attached to a water system. The water system pipe isolation insert segment is coupled together with a solid inner core center on its opposite end. A water main pipe isolation insert segment is coupled to the solid inner core center and to the water main pipe on the other. Each of the pipe segments possess a 2? c.c. threaded hole along a common center line of the pipe segments. A backflow preventer may be attached to the positive stop flow pipe isolation insert using the pair of 2? c.c. threaded holes to use during pressure testing and chlorination.

Abstract: An apparatus and method for micro-machining a surface of a workpiece having a complex surface profile including desired profile features and finer undesired profile features to be removed, including shaping a formable polishing tool using either the workpiece itself or a replica of the workpiece to have at least said desired profile features, and using said formable polishing tool to micro-machine said surface to remove said finer undesired profile features while maintaining said desired profile features. The formable polishing tool can be shaped to have at least said desired profile features by pressing the formable polishing tool against either the workpiece itself or the replica of the workpiece when the formable polishing tool is in a formable state, and the formable polishing tool can be used for micro-machining when the formable polishing tool is in a solid state.

Abstract: A method and device for cleaning at least an end face of an optical device retained within an optical connector using a cleaning fabric, comprises, alone or in combination, a) preventing the cleaning fabric from contacting the connector prior to contacting the end face of the optical device; b) a cleaning nose being made of a nose material having a hardness less than that of a material of the optical device with a flexural modulus greater than 2700 MPa and c) ensuring a constant tension on the fabric as it is circulated.
