An adapter for a swinging bucket centrifuge rotor includes a slide plate having a retaining lip and a cam surface thereon. Movement of the plate in one direction to a holding position disposes the lip to hold above the rim of a microtube to hold the same in place. Movement in an opposite direction introduces a cam surface between the rim of the tube and a flange on a closure to thereby uncap the same.

Disclosed is a process for purifying carbon nanotubes which has steps of 1) mixing carbon nanotubes which accompany carbon impurities with a reagent selected from a group consisting of oxidation agents, nitration agents and sulfonation agents in liquid phase, 2) reacting the carbon nanotubes with the reagent at a predetermined temperature in the liquid phase, wherein the carbon impurities except carbon nanotubes are selectively reacted to dissolve in the liquid phase, and 3) separating carbon na...

This invention is an improved method of removing the sealing wax of a honeycomb in preparation for removal of the honey contained therein. The process includes the providing of heating elements about the entrance of the chambers of the comb which, when electrical current is passed therethrough, will cause the beeswax sealing the chambers to soften. Also an improved centrifugal extractor is provided to further assist in honey removal.

A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing print media past the printhead in a feed direction during printing; and (c) a capping mechanism including a capper moveable between: a capping position in which the capper is urged into a capping relationship with the printhead; and an uncapped position in which the printhead is able to print onto the print media, wherein in the uncapped position the capper is displaced away from the printhead; wherein ...

A screw cap comprises a main cap portion 1 having screw threads on its inner circumferential surface and a number of splines 6 axially extending on its outer circumferential surface, and a ring portion 11 having a projection 12 on its inner circumferential surface and a number of splines 13 extending on its outer circumferential surface and continuous from the splines 6 of the main cap portion. The ring portion 11 is spaced apart from and connected integrally with the lateral wall of the main ca...

A continuous motion high-speed rotary machine of the turret type which has a plurality of angularly spaced filler heads thereon, each equipped with movable uncapping and capping means and a movable filler nozzle. As the turret rotates continuously, an individual bag spout is partially inserted into the approaching filler head. These bags are of the flexible type, each having a spout with a removable cap pressed thereon. The individual bags may be presented to the successive continuously-moving f...
