摘要:
The present disclosure features tube insertion devices that are configured to allow a user to manually insert a hollow tube into a receiving bore, e.g., a pen tube into the bore of a blank. The disclosure also features methods of using such devices. In some implementations, the devices comprise (a) a pair of elongated arms, each arm comprising a gripping portion and an insertion portions, each of the insertion portions terminating in a distal tip, and (b) a connecting portion joining the arms such that the arms pivot about the connecting portion in a plane defined by the arms when the gripping portions are pressed together by a user. Each of the insertion portions preferably includes a relatively wider proximal portion and a relatively narrower distal tube-carrying portion, the change in width between the proximal portion and the distal portion defining a stop surface.

Compute clustering software embodied in a computer-readable medium and operable to provide a graphical user interface (GUI) is provided, the GUI operable to present a selection area for illustrating a plurality of receptors in a chassis, each receptor configured to couple to a network device, wherein the selection area conveys a physical location of each of the plurality of receptors, receive information from a user to create a defined cluster by pointing and clicking on a portion of the plurality of receptors illustrated in the selection area, present an image selection window with a plurality of software image choices, receive an image selection for each of one or more selected receptors in the defined cluster, and wherein the software is operable to associate each logical address of the defined cluster with a not necessarily same selected one of the plurality of images.
摘要:
A method for making electrical interconnections of carbon nanotubes, including a) depositing an ionic liquid including nanoparticles of at least one suspended electrically conducting material, covering at least one surface of an element configured to be used as a support for carbon nanotubes, b) forming a deposit of the nanoparticles at least against the surface of the element, c) removing the remaining ionic liquid, d) growing carbon nanotubes from the deposited nanoparticles, and further including between the c) removing the remaining ionic liquid and the d) growing carbon nanotubes, passivating the deposited nanoparticles not found against the surface of the element.
摘要:
A variable frequency down hole drill, includes a drill bit, a reciprocating piston operable to deliver an impact load to the drill bit, and means for changing the frequency with which the piston delivers impact loading to the drill bit, also resulting in a change in overall power of the drill. The means for changing frequency and overall power may operate during continuous operation of the drill. The means for changing the frequency and overall power may include a valve for selectively changing the effective volume of a drive or return chamber, an actuator for changing the timing of placing the drive or return chamber in communication with exhaust, or a system for changing the frequency in response to sensing an predetermined operating parameter of the drill, such as pressure or piston position.

摘要:
A retaining assembly for a cylindrical member and support sleeve in the bore of a component of a DTH. The cylindrical member and support sleeve may, for example, be a foot valve assembly for insertion into a counter bore in a bit. The cylindrical member has a cylindrical member rigidity and at least a portion of the support sleeve has a rigidity greater than the cylindrical member rigidity. A gap is provided between the sleeve and the component bore of the DTH. The cylindrical member deforms in the gap, resulting in the cylindrical member being fixedly sandwiched between the support sleeve and the component bore.
摘要:
An improved side loading garbage truck that includes an improved packing method that utilizes a packing blade that doubles as the hopper cover, that includes its hydraulic cylinders outside the body of the truck, does not have any potential leak points inside the body and includes all grease points outside the body providing easier access to the cylinders, blade and grease points for maintenance and installation. The other improvement is the use of multi-point contact rollers thereby reducing wear and tear and extending the life of the side loader arm.
