Abstract: Methods of processing a superabrasive element may include disposing one or more superabrasive elements in one or more protective leaching cups and exposing the leaching tray to a leaching agent such that at least some of the leaching agent contacts the one or more superabrasive elements while disposed in the one or more protective leaching cups.

Abstract: In an embodiment, a protective leaching cup may include a base portion, at least one sidewall defining an opening general opposite the base portion, and a receiving space in communication with the opening and at least partially defined by the base portion and the sidewall. The receiving space is sized and configured to receive at least a portion of the superabrasive element. A seal contact portion is located on an inner surface of the sidewall. The seal contact portion is configured to form a seal against the superabrasive element that is at least partially impermeable to fluid(s). At least one of the seal contact portion or the sidewall includes material(s) exhibiting a flexural modulus greater than about 150,000 psi at room temperature.

Abstract: A method for reducing media skew in a media advance mechanism according to embodiments of the invention includes applying tension to a roll of media in a direction that opposes forward motion of the media, advancing the media, and reversing the media.

Abstract: Methods and electric power control apparatus connected to a parallel port of a computer. The methods and apparatus permit sharing the parallel port with a printer and allow computer power off without being disturbed. The apparatus transmits status information back to the computer and also reacts to a signal from a timer, a telephone call, user switch, etc. The apparatus is also used for powering on and powering off connected equipment automatically.
