Abstract: ABSTRACT OF THE DISCLOSURE The subject invention provides a method of making a pocket folder having a plurality of page inserts from a pre-printed web. A first fold line is provided along a first transverse line which divides the web into integral folder and insert sections. A second fold line is provided along a second transverse line adjacent an end of the folder section opposite the insert section, thereby forming a folder pocket member. A third fold line formed along the longitudinal midline of the folder portion divides the folder portion into first and second cover sheets. The insert section is cut inside of and parallel to opposite longitudinal edges of the web to form lateral marginal portions. The insert portion is also cut adjacent to and parallel with the longitudinal center line to form a pair of insert pages separated by a medial marginal portion. The lateral and medial portions are removed and the insert pages are folded along the first transverse fold line to superpose the folder cover sheets. The folder pocket member is folded along the second transverse fold line into superposition with the insert pages and the folder cover sheets to create folder pockets for the insert pages. The insert pages are then separated from the folder cover sheets to provide a pocket folder having removable page inserts. The folder as well as the page inserts may be personalized to the recipient to facilitate use of the pocket folder in direct mailing campaigns.

Abstract: ABSTRACT       ETCHED GLASS AND PROCESS OF MANUFACTURING SAME    The invention relates to an article comprising  a glass sheet and having an etched pattern, and to a process of manufacturing an article  comprising a glass sheet  and having an etched pattern.         The glass sheet 11 is a chemically tempered glass sheet, and the  pattern comprises one  or more grooves  10 etched into the article using fluorine ions to a depth  of less than 2µm.   The  etched grooves  10 constituting  the pattern may be formed in a layer 12 of inorganic  material such as SiO2.  They may have a width of less than 10µm and the spacing (p) between two  adjacent grooves may also  be less than 10µm.         The etching may be performed by applying a  layer of radiation-sensitive material  to at least  one face  of that sheet and exposing it  to radiation to form a  latent image  of  a  desired   groove  pattern,  whereafter   the radiation- sensitive  material  is  developed  to  form a resist and the  sheet is exposed,  through the resist,  to the action of fluorine ions  in an etching medium to  etch the desired groove pattern to a depth of less than 2µm.
