Abstract: A thermal ribbon having a minute coating of graphite powder on the outer side of the resistive layer. The improved electrical interface with print electrodes reduces ribbon and printhead damage. The graphite also reduces friction and loosens material which builds-up at the printhead.

Abstract: A fret assembly for a stringed musical instrument having an elongated neck body, comprising a ladder-like structure including a pair of elongated support rods upon which are fixed a plurality of longitudinally spaced, transverse fret bars, and a clamp member for detachably securing the support rods longitudinally upon the top surface of the neck body.

Abstract: In a continuous type ink jet printer having a conventional charging electrode for charging ink drops in accordance with a signal to be recorded on a record receiving medium, at least one, and preferably both of the deflection electrodes is mounted so that the deflection electrodes may be positioned in a first position by an actuator to allow for printing in a first direction. The actuator tilts the electric field to compensate for character inclination during carrier movement, and at the opposite end of the print line rotates the deflection electrodes to a second position to incline the electric field to compensate, during carrier movement in that opposite direction, for character inclination due to carrier movement in the second direction.

Abstract: A guitar assembly including an elongated, channel-shaped, open-top, neck body upon which are mounted a plurality of longitudinally spaced, transversely disposed, free-spanning fret bars.

Abstract: In a xerographic printing system the toned copy paper is fused by the pressure nip formed by a hot roll and a backup roll. A scraping blade engages the destructible surface of the backup roll at a critical angle which is selected as a function of the coefficients of friction of the backup roll's surface and the toner/debris contamination that may be collected on the backup roll's surface. As a result, the blade slides freely on the roll's surface, but does not slide on the surface of the toner/debris contamination film. This film forms a locking angle with the blade, placing the blade in stress, and developing a film removing chisel-like action therewith.
