摘要: In one aspect, methods of nanopore formation in solid state membranes are described herein, In some embodiments, a method of forming an aperture comprises providing at least one solid state membrane in a chamber, selecting a first dose of ions sufficient to provide a first aperture of predetermined diameter through the membrane and exposing a surface of the membrane at a first location to the first dose of ions in a focused ion beam having a focal point of diameter less than or equal to about 1 nm to remove material from the membrane at the first location thereby providing the first aperture having the predetermined diameter or substantially the predetermined diameter.

摘要: A dual pipe drill string system having increased fluid flow. The dual pipe system comprises a plurality of pipe sections, each pipe section having an inner rod and an outer pipe. The inner rod and the outer pipe of each pipe section may be coupled to the inner rod and outer pipe of an adjacent pipe section. An annulus between the inner rod and the outer pipe defines a fluid flow path through the dual pipe system. The outer pipe defines a shoulder at each end of an individual pipe section. The inner rod defines at least one stop for maintaining the inner rod within the outer pipe. A spacing assembly disposed around the circumference of the inner rod defines paths for fluid flow and maintains a minimum distance between the stop and the shoulder at one end of outer pipe of the pipe section.

摘要: A pipe handling assembly for transporting pipe sections to and from the drill string of a horizontal boring machine. The system comprises a magazine, a cradle for supporting the magazine, a support member, a drive system, and a transfer assembly. The drive system may move the cradle and the magazine laterally on the support member or may pivot the magazine. The transfer assembly transfers pipe sections between the magazine and the spindle connection area. The magazine and the support frame are disposed above the spindle connection area such that only empty columns of the magazine are outside of the footprint of the boring machine. The magazine may be removed from the cradle when empty or full to continue with the boring operation.

摘要: A dual pipe drill string system having increased fluid flow. The dual pipe system comprises a plurality of pipe sections, each pipe section having an inner rod and an outer pipe. The inner rod and the outer pipe of each pipe section may be coupled to the inner rod and outer pipe of an adjacent pipe section. An annulus between the inner rod and the outer pipe defines a fluid flow path through the dual pipe system. The outer pipe defines a shoulder at each end of an individual pipe section. The inner rod defies at least one stop for maintaining the inner rod within the outer pipe. A spacing assembly disposed around the circumference of the inner rod defines paths for fluid flow and maintains a minimum distance between the stop and the shoulder at one end of outer pipe of the pipe section. An additional spacing assembly disposed around the circumference of the inner rod defines paths for fluid flow and maintains a minimum distance between a second stop on the inner rod and the shoulder at a second end of the outer pipe of the pipe section. Alternatively, the stops on the inner rod may define a feature of the stop defining fluid paths for when the stop contacts the shoulder.
