Patent number: 5521268Abstract: The present invention is a process for making an electrophotographic toner binder. The toner binder has reduced mercaptan odor at elevated temperatures. The toner binder is formed by mixing monomers in a ratio that determines the final composition of the polymer or toner binder and contacting the monomers with air or oxygen. A chain transfer agent and polymerization initiator are added to the monomers. A suitable suspension polymerization type aqueous phase is prepared. The aqueous and monomer phases are blended and sheared to form monomer droplets, the mixture is suspension polymerized by heating and the aqueous phase is removed from the polymer beads.Type: GrantFiled: March 29, 1995Date of Patent: May 28, 1996Assignee: Eastman Kodak CompanyInventors: Peter J. Ghyzel, Paul Mitacek, Dennis E. Smith

Patent number: 5482474Abstract: Electrical connectors (1,2) attach to the top and bottom surfaces (22,23) of a circuit board (PCB) (3) and thereby form a sandwich connector (4) such as for board-to-board interconnection. The electrical connectors (1,2) include on their bottom surface (13) a fastener (14) and a recess (15). A first electrical connector (1) attaches to the top surface (22) of the PCB (3) by inserting its latching means (14) into a first aperture (18) of the PCB (3). The second electrical connector (2) attaches to the bottom surface (23) of the PCB (3) through a second aperture (19) of the PCB (3). The leading end of the fastener (14) of each connector (1,2) projects beyond a surface of a PCB (3) for latch (16) to latch, and is received in a recess (15) of the other connector (2,1).
