    Abstract: This invention is directed toward a method for obtaining a resinous toner image fixed to a copy substrate. The method involves applying to a copy substrate in image configuration a toner of specific polymeric composition and fixing the image to the copy substrate by the application of heat sufficient to fuse the toner. The toner composition comprises a finely divided mixture comprising a coloring material and a polymeric material which is block or graft copolymer consisting of at least one crystalline or crystallizable polymeric segment chemically linked to at least one amorphous polymeric segment, said crystalline or crystallizable segment individually having a glass transition temperature of less than about 20.degree.C and a melting point of at least about 45.degree.C, and said amorphous segment individually having a glass transition temperature less than the melting point of said crystalline or crystallizable segment. Toner materials according to the present invention exhibit thermal and mechanical properties which render them extremely useful in xerographic processes, particularly high speed process involving contact or flash fusing.

    Abstract: A multi-stage extendable tower for controlled elevated support and positioning of workmen and equipment having a plurality of telescoping frame sections that may be raised from a collapsed nested position to a partially or fully extended position. Functionally positioned and interconnected between each adjacent frame section is at least one heavy-duty coiled spring whose potential energy stored in torsion provides sufficient lifting force to overcome the weight of the above frame members, workmen and equipment. Both manual and motorized means are disclosed and claimed for effecting compression and renesting of the frame members.
