Abstract: A reproduction system is described having an approved ink applicator arrangement. The reproduction system includes a means for establishing latent electrostatic images on a photoreceptive surface, a means for developing said latent electrostatic image by applying a polar ink to imaged areas of the surface, said developing means having an ink applicator body which is positioned adjacent said photoreceptive surface for transferring ink from said applicator body to said photoreceptive surface, said applicator body having an array of lands and depressions formed on a surface thereof, including superficial grooves being arranged substantially perpendicular to the revolution axis of the developer roller, said grooves being formed by the winding of synthetic resin filament about said cylindrical roll; said synthetic resin filament having been coated with an adhesive solution containing formic acid.

Abstract: A device utilized for the inhalation of medicament in a powder form. This device has a body portion with communicating primary and secondary air inlet channels and an outlet channel. The secondary inlet channel provides an enclosure for a capsule containing medicament and the outlet channel is formed in a mouthpiece protruding from the body portion. A capsule piercing structure is provided, which upon rotation puts holes in the capsule, so that upon vibration of the capsule, caused by an electro-mechanical vibration means, medicament is ejected from the capsule. After piercing and upon inhalation through the mouthpiece, and activation of the vibration means, powder is ejected into the airstream passing through the inlet channels, outlet channel, and into the user's mouth.
