摘要： A bicycle saddle construction in which the saddle pan is attached to a one-piece saddle support which underlies and supports the pan. The support includes an upper plate and a downwardly extending skirt, and an intermediate section of the skirt is deformed inwardly to form a downwardly opening socket into which the upper end of a seat post is received and permanently fixed in place by welding.

摘要： Liquid developer compositions for development of latent electrostatic images are disclosed. The electrostatic printing inks dry at ambient temperatures by penetration into paper leaving a continuous film having excellent rub resistance on the surface. The non-volatile, low viscosity inks comprise about 3-20% pigment and/or dye, about 5-35% of resinous particles having a size of 5 microns or less and having glass transition temperatures close to or below ambient temperature, said resinous particles being dispersed in the liquid carrier, 0-25% dispersing agent and about 25-90% non-volatile, high boiling organic liquid carrier and/or solvent.
