40420914, Aug 16, 1977

Filed:

Mar 25, 1976

Appl. No.:

5/670464

Inventors:

Leo Levinson - Berkeley CA
Andrew Wong - Fremont CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41J 1504

US Classification:

197138R

Abstract:

Record material feed apparatus for use with a printing machine of the type including a platen, means for rotating the platen about its axis, at least one roller, a lever capable of manual movement between first and second positions, and means coupled between the lever and the roller for maintaining the roller in engagement with the platen when the lever is in its first position and for maintaining the roller spaced a predetermined distance from the platen when the lever is in its second position. The feed apparatus comprises a drive assembly capable of engaging and, when enabled, feeding a marginally punched record material that is loaded thereon, a guide rack coupled to the drive assembly and capable of manual movement between a first position in which a record material may be loaded onto the drive assembly and a second position in which a record material fed by the drive assembly may be guided along the guide rack, and means coupled to the guide rack and capable of engaging the lever when the feed apparatus is mounted to the printing machine for automatically moving the lever from its first position to its second position when the guide rack is manually moved from its first position to its second position, and for automatically returning the lever to its first position when the rack is manually returned to its first position.

Abstract:

This disclosure provides systems, methods, and apparatus related to inorganic halide perovskite nanowires. In one aspect, a first solution comprising cesium oleate or rubidium oleate in a first organic solvent is provided. A second solution comprising a lead halide and a surfactant in a second organic solvent is provided. The halide is selected from a group consisting of chlorine, bromine, and iodine. The first solution and the second solution are mixed. A reaction between the cesium oleate or the rubidium oleate and the lead halide forms a plurality of nanowires comprising an inorganic lead halide perovskite.
