Patent number: 11399648Abstract: The present invention relates to a parcel receptacle device that allows for securely receiving packages and transferring the packages to the interior side of a wall or door which the parcel receptacle device is attached. This device is comprised of a plurality of elements including an interior mounting plate, an exterior mounting plate, a housing and a drawer. The housing and drawer may be detached from an interior mounting plate that is affixed to the wall or door. This device also provides an auto-locking door that automatically closes when the housing and drawing are detached. Accordingly, the auto-locking door securely closes the opening in the garage door, which previously allowed the drawer to slide through. The receptacle can later be reattached by unlocking the auto-locking door and then raising it upward. Once it is raised up to a pre-determined position, the housing and drawer may then be reattached to the interior mounting plate.Type: GrantFiled: October 13, 2020Date of Patent: August 2, 2022Inventor: John D.

Patent number: 4551731Abstract: An ink jet array printer has at least one row of printing guns. The guns deposit drops which are charged and deflected for printing on a printing surface moving relatively to the printer in line sections which together form a transverse printing line. The charging of the drops is effected by applying to the charge electrode of each gun, under the control of printing information, a periodic voltage waveform of sufficient period to span a raster of successively formed drops which are employed for printing the corresponding line section, the printing lines being successively formed at the frequency of the voltage waveform.Type: GrantFiled: August 8, 1983Date of Patent: November 5, 1985Assignee: Cambridge Consultants LimitedInventors: John D. Lewis, Michael R. Keeling, David R. Bowen, Anthony D. Paton

Patent number: 4384295Abstract: An ink jet array printer in which the printing voltage waveform applied to each raster of drops formed in each printing gun comprises at least two successive sets of voltage levels which each arrange the raster drops in a group in time order of drop formation for each set of voltage levels so that corresponding drops in each of the groups formed in the raster, if charged for printing, have similar differences of voltage level and have similarly spaced print locations in the line section of drops printed by the printing gun. First and second correction voltages are applied to the charging voltage levels, the first to correct for the influence of the preceding drop and the second for the electrostatic and aerodynamic drag forces of a small number of drops influencing the drop being corrected. The set of second correction voltages derived for any particular drop being used also for corresponding drops in the other group(s).Type: GrantFiled: March 23, 1981Date of Patent: May 17, 1983Assignee: Cambridge Consultants Ltd.Inventors: John D.
