Abstract: A cleaning swab is for wet or dry use. The swab includes a handle defining a longitudinal axis. The handle is elongated and has a cleaning head end having a tip, and a grasping end. A cleaning head is mounted to the handle. The cleaning head is formed from a strip of material having an inner surface and an outer surface. The material is affixed to the handle at the inner surface, and extends along the handle, over the tip and along an opposite side of the handle. The head defines a loop at the handle tip spaced from the tip. The strip of material extends along the handle to define major cleaning surfaces and the loop defines an inner annular cleaning surface.

Abstract: A therapeutic composition derived from a pre-activated photoactive compound and a conveyor for destroying tumor or other pathogenic biological contaminants infecting animal body tissues. The conveyor can either be a matrix support or an antibody. The activation of the photoactive compound to produce the pre-activated photoactive compound is carried out by the use of an activating agent. The pre-activated photoactive compound retains its therapeutic activity subsequent to activation. A method for preparing such a therapeutic composition is disclosed. Methods for treating animal body tissue, either outside the body or inside the body, infected with tumors or other pathogenic biological contaminants are disclosed.

Abstract: A pre-activated therapeutic agent derived from a photoactive compound for destroying tumor or other pathogenic biological contaminants infecting animal body tissues. The activation of the photoactive compound is carried out prior to the photoactive compound is being brought into contact with the tissue to be treated. The resultant pre-activated therapeutic agent, or mixture, retains its therapeutic activity subsequent to activation. A method for preparing such a pre-activated therapeutic agent is disclosed. Methods for treating animal body tissue, either outside the body or inside the body, infected with tumors or other pathogenic biological contaminants are disclosed.

Abstract: Electrostatic deflection is used to provide multiline printing from a single pass in an oscillating bar ink jet printer.

Abstract: Photosensitive composition for use in photoelectrophoretic imaging system. The particulate component of this composition includes vanadyl phthalocyanine pigment particles which have been treated with a polymer having structural units of the formula ##STR1## WHEREIN Z is a pendant group of the formula ##STR2## X is a substituent substantially incapable of withdrawing electrons from the electron rich pyridinyl moiety;M is a whole number from 0 to 3; andN is a whole number in excess of 25.The intimate association of at least some of the polymer with at least some of the vanadyl phthalocyanine pigment is believed to effectively attenuate photoinjection of holes from the phthalocyanine pigment into the surrounding materials thereby both reducing the D.sub.min of the phthalocyanine pigment; and, to improve color separation of reproductions prepared by processes employing a subtractive color system.

Abstract: An electrophoretic imaging process wherein a suspension of particles in a carrier liquid are placed between a photoconductive electrode and a second electrode. With an electrical field applied between the photoconductive electrode and the second electrode the photoconductor is exposed to imagewise radiation which causes particles on the surface of the photoconductive electrode to be driven away in image configuration by charge exchange with the photoconductive electrode. The migrating particles form a negative image on the second electrode leaving a positive image behind on the photoconductive electrode.
