  • Patent number: 5521268
    Abstract: 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.

  • Patent number: 5482474
    Abstract: 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). Surface mount leads (8) project from the front surface (7 ) of both connectors (1,2) and are soldered to pads (11,12) on the surfaces (22,23) of the PCB (3).

  • Patent number: 4934950
    Abstract: Keying and fastening of mating connectors includes pairs of mating key members, ones of which include central apertures through which extend respective jackscrews having threaded leading ends, and the others of which have threaded apertures into which the jackscrews are threaded to fasten the connectors together after the pairs of keys permit connector mating. The keys in which the jackscrews are mounted permit rotating the jackscrews. The jackscrew leading ends are recessed slightly behind the leading ends of hood-like keying projections of the key members for protection against damage and misalignment, and the threaded apertures of the other keys extend to the leading ends of the keying projections thereof which are adapted to receive the corresponding hood-like keying projections in axial recesses along the outer surfaces extending about halfway around the circumference of the key.

  • Patent number: 4912009
    Abstract: An electrophotographic dry toner having excellent properties with respect to charging, RH stability and fusing is made in a process in which the binder polymer is formed by suspension polymerizing a styrene-acrylic monomer mixture in the presence of a polyester-promoted colloidal silica suspending agent which is free of other hydrophilic polymers. The resulting polymer is melt blended with toner addenda such as a colorant and a charge control agent and the mixture is pulverized to form the toner composition.
