摘要:
A liquid composition for developing latent electrostatic images comprising toner particles associated with a pigment dispersed in a nonpolar liquid. The salient feature of the invention is that the toner particles are formed with a plurality of fibers or tendrils from a thermoplastic polymer and carry a charge of a polarity opposite to the polarity of the latent electrostatic image. The polymer is insoluble or insolvatable in the dispersant liquid at room temperature. The toner particles are formed by plasticizing the polymer and pigment at elevated temperature and then either permitting a sponge to form and wet-grinding pieces of the sponge or diluting the plasticized polymer-pigment while cooling and constantly stirring to prevent the forming of a sponge while cooling. When cool, the diluted composition will have a concentration of toner particles formed with a plurality of fibers.

摘要:
A measuring ruler, tape or other instrument having a straight edge located along at least one length of the ruler. The ruler has a first surface having a background color, and a second opposed surface. The ruler also has a set of spaced apart indicia located on the first surface along the at least one length. The indicia are oriented perpendicular to the straight edge. The width of the first indicium and last indicium of a whole number unit measurement length appear half as wide as the width of all remaining fractional indicia.
