Patent number: 4462428Abstract: The illustrated embodiment teaches a three-way valve system for an ink jet printer. The system has an inlet, a main outlet, a vent, and two needle valves (a shut-off valve and a vent valve) which sit in respective valve guides. The passageways are arranged so that for ink to reach the outlet or vent, it travels through the shut-off valve seat and guide. Similarly, to reach the vent, fluid must pass through the vent valve seat and guide. The shut-off valve and vent valves are arranged to reciprocate through the action of a lever with a fulcrum between the two needle valves. The lever is connected to an actuator solenoid and an opposing bias spring. For opening of the valve system, the solenoid pulls the lever to shut the vent valve, thereby permitting the pressurized ink to lift the shut-off valve off its seat. When the shut-off valve is seated, a smaller area is exposed to pressure than when it is not seated. Therefore, the ink exerts a greater force on the opened shut-off valve.Type: GrantFiled: February 22, 1982Date of Patent: July 31, 1984Assignee: Bell & Howell CompanyInventors: Kenneth L. Guenther, Edward H. Zemke, Gerald D. Warden

Patent number: 4389478Abstract: A bimodal electrophotographic apparatus and process which incorporates capabilities for making both positive and reversal copies. One surface of a layer of a zinc oxide coated paper, or the like, is given an initial electrostatic charge. The charged surface is then exposed to an image having light and dark areas for causing surface charge to dissipate, in varying degree depending on the amount of light striking the charged paper, in the exposure areas. A charged toner is applied to the zinc-oxide-coated paper by a magnetic brush. In the reversal mode, the brush has a bias potential. The brush is formed by an aggregation of magnetic toner particles clinging to the outside of a cylindrical sleeve while magnets inside the sleeve rotate. The toner collects on the paper to form an image depending upon where the charge is dissipated.Type: GrantFiled: June 22, 1981Date of Patent: June 21, 1983Assignee: Bell & Howell CompanyInventor: Rudolph Guzik

Patent number: 4328402Abstract: A document switch senses the movement of a plurality of cards, or the like, as they pass through a path of travel. A pivotable assembly has first and second pivoted arm members including a sensing arm mounted on a pivotable element. In its initial position, the sensing arm projects into the path of card travel. When the card appears, the sensing arm is moved out of its initial position, and a contact mounted on the assembly opens to sense an engagement of the arm with a card. Continued travel of the card moves the arm against a stop which withdraws it from the path of travel and resilient means brings the sensing arm into engagement with the underside of the card. A leaf spring presses against the card to retain it in a guide plane as it travels away from the sensing arm and into the nip of take-up rollers.Type: GrantFiled: August 27, 1979Date of Patent: May 4, 1982Assignee: Bell & Howell CompanyInventor: Daniel D.
