Patent number: 5324359Abstract: A material deposition device places droplets on a substrate. A conveyer on a chassis moves the substrate relative to a plane so a deposition means on the chassis may release material onto the substrate moved by the conveyer. A movable support means attached between the chassis and the deposition means locates it with respect to the conveyer allowing relative motion therebetween. A supply of material connected to the deposition means sends pressurized material thereto. A control causes relative motion between the conveyer and the movable support means varying the position of the deposition means relative to the substrate. The control has a memory operatively connected to timely activate the deposition means. The deposition means has a body communicating with the supply of material and a valve means responsive to the control selectively delivers droplets to the substrate.Type: GrantFiled: February 25, 1992Date of Patent: June 28, 1994Assignee: Nouvas Manufacturing Technology Co.Inventors: Wade J.

Patent number: 4449241Abstract: A toner cleaning apparatus for use in an electrophotographic copying machine in which a photosensitive drum is rotated for a few revolutions after transferring, onto a record paper, a toner image obtained by developing an electrostatic latent image with toners, in order to remove residual toners from the drum and to prepare the drum for the next duplicating operation. A cleaning device, such as a fur brush, is arranged movably with respect to the photosensitive drum and is separated from the drum after the end of a copying operation, but before the drum is stopped. The cleaning fur brush is removed from the drum at such a timing that the pictorial area on the drum surface has just passed through the cleaning fur brush and thus, residual toners on the drum can be effectively removed. By shortening the time duration in which the cleaning fur brush is brought into contact with the photosensitive drum, the drum can be protected against injury, deterioration and filming.Type: GrantFiled: May 27, 1982Date of Patent: May 15, 1984Assignee: Olympus Optical Company LimitedInventor: Shigeru Nakayama

An arm is coupled to a vertical drive shaft which is rotatable about the center axis. The arm is designed to move a circular cover from opening-to-opening to individually seal the openings from the chamber, so that the filters can be cleaned of zinc powder. The cover is freely mounted on the distal end of the arm such that the cover is supported on the bottom surface of the chamber as it moves in an arcuate pathway between the filter openings.Type: GrantFiled: November 27, 1981Date of Patent: May 24, 1983Assignee: Midland-Ross CorporationInventor: Robert M.

Patent number: 4378421Abstract: A method and apparatus for cleaning residual toner from the surface of an imaging member in an electrographic imaging system which uses carrier means to transport toner by triboelectric forces to develop an electrostatic image on the imaging member. The pre-clean corona current is adjusted periodically during the lifetime of the carrier as necessary substantially to neutralize the charge on residual toner so that it may readily be removed by a rotating cleaning brush having substantially no charge thereon. Adjustment is in response to a periodically sensed aging characteristic, the charge density of the toner, such as at successive preselected operating time intervals representing increments of carrier useful lifetime. In this manner, cleaning efficiency is maintained.Type: GrantFiled: December 22, 1980Date of Patent: March 29, 1983Assignee: International Business Machines Corp.Inventor: Wallace B. Larson

Patent number: 4357900Abstract: An apparatus is disclosed for the automatic coating of articles. The apparatus has a spray device controlled by a programmed control device. A transport device transports the articles along a predetermined path to a coating position and then away therefrom after coating. A sensor monitors the position of the article and generates signals representative thereof, preferably generating one signal each time the article moves a predetermined distance (e.g. 2 cm.) along the path. A second sensor generates additional signals to the control device when an article passes a predetermined point, also indicating which of several types of articles has been detected. The control device controls the spraying process responsive to these signals. If desired, portions of the article that are moved sequentially into the coating position can be sprayed in different manners, e.g. with the spray devices positioned or oriented differently, or using different coating materials, etc. The control device is preferably reprogrammable.Type: GrantFiled: April 3, 1981Date of Patent: November 9, 1982Assignee: Gema AG ApparatebauInventor: Karl Buschor

Patent number: 4318363Abstract: An enclosed spray chamber for the application of toxic compounds in micro liquid volumes as a function of time using air as a carrier. The spray chamber is cylindrical and vertically mounted about its longitudinal axis. A spray nozzle is mounted in the top of the spray chamber which uses a syringe and needle reservoir system as an accurate means of controlling the amount of solute dissipated. An air pump provides a stream of air that passes in front of the spray nozzle which pulls the spray solute and solvent out of the syringe by vacuum. An exhaust fan and exhaust outlet are provided to safely dispose of the spray solute and solvent outside of the working area of the chamber. A timer system operates the exhaust fan and air pump so that spray droplet fallout and impingement time can be varied and calibrated.Type: GrantFiled: May 9, 1979Date of Patent: March 9, 1982Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Emanuel E.
