Abstract: A system, including a specially-designed optical element, facilitates extremely precise and accurate registration of a light beam on a photoreceptor. The optical element includes a redirecting cylinder lens, having a longitudinal axis oriented obliquely relative to the scan path of the light beam to redirect the light beam. The redirected light beam interacts with an aperture in the photoreceptor to provide an accurate measuring device for the exact position of the aperture with each scan.

Abstract: An ionographic printer directs a stream of ions from a source to a charge receptor to create an electrostatic latent image thereon. The ion stream passes through a relatively large aperture having associated therewith a focusing pinch electrode for narrowing the ion stream to a preselected width, and displacing electrodes for positioning the narrowed ion stream within the aperture. Varying the biases of the displacing electrodes causes the ion stream to scan across the aperture to deposit multiple spots of charged areas at desired locations on the receptor.

Abstract: A cap actuation mechanism for placing a cap, movably mounted on a cap carriage of an ink jet printer maintenance station, into sealing engagement with the nozzle face of the printhead of the printer.

Abstract: A transport apparatus for a weighing module includes a scale which has a deck connected to a scale base for weighing an object placed on the deck. The deck has slots for accommodating dual thickness belts which are arranged below the deck to be in substantial registration with the slots. The belts are positioned with respect to the slot such that in a home position a thinner section of the belt does not protrude through the slot whereby the transport means does not interfere with weighing of the object on the deck. When the belts are actuated, the dual thickness belts move so that a thicker section of each belt protrudes through the slot as the belts are being driven to thereby lift the object from the deck onto the thicker section of the belt to transport the object on the belt.

Abstract: Apparatus for protecting optical elements of an optical ink drop detector that detects the presence of an ink drop in a drop detection zone, and for maintaining an aperture plate used in conjunction with the ink drop detector. The apparatus includes a movable plate having an apertured region and a non-apertured region. The plate is movable relative to the optical elements of the drop detector and is configured to have the aperture region adjacent a drop detection zone of the optical ink drop detector when in a first position and to have the non-apertured region adjacent the detection zone when in a second position. Cleaning brushes are provided for cleaning ink from the aperture region of the movable plate when the plate is moved between the first and second positions, and an enclosure is provided for enclosing the aperture region of the plate when said plate is in the second position.

Abstract: An apparatus for improved paper marking is provided which increases the percentage moisture content of the paper, thereby decreasing its electrical resistivity. The paper is then dried at selected pixels which results in high electrical resistivity of those pixels. Subsequently, the paper is charged with a high negative voltage. The areas with high moisture content rapidly discharge the applied charge, whereas the areas with low moisture content retain the charge. Finally, the areas with retained charge attract toner and are fused to the paper.

Abstract: A method for determining a weight of material being emptied from a container is shown. The container is lifted to and lowered from an emptying position in a lift empty and lower cycle by an arm which has at least two sensors mounted on it. The method includes selecting at least one measurement position, calibrating the sensors by recording the respective outputs from each of the sensors for both an empty arm and for an arm lifting and lowering a calibrating weight. The outputs recorded for the calibrating weight can then be subtracted from the outputs recorded for the empty arm. Then, an unknown load can be lifted emptied and lowered with the output of the sensors being similarly recorded at the measurement position. By subtracting the output recorded during the lifting portion of the cycle for the unknown load from the output recorded during the lowering cycle for the unknown load a change in output for each sensor at the measurement position can be obtained.

Abstract: There is disclosed, a gross weight scale for filling material which can be poured or which can flow. The filling material is weighed by means of weighing cells and is filled by way of a filling connection into a bag suspended therefrom and is then compressed. In order to keep the weighing cells free of the compressive forces and so as to be able to check between each filling of the bag, the zero points of the cells in respect of permitted weighing tolerances, the filling connection is constructed as a structural unit which is separate from the filling container and is loosely suspended by means of a hanger arrangement from the weighing cells, which are attached to the filling container, and a decoupling arrangement is provided for bringing the filling connection out of operative engagement with the hanger arrangement.

Abstract: In electrostatic imaging utilizing a silent electric discharge, nitrogen or other controlled gas is supplied to the discharge region. First and second control fingers each having first and second ends and a number of active openings along their lengths, provide electrodes at the discharge region. The controlled gas is supplied to the discharge regions through first and second gas input channels each connected to either the first ends or second ends of both the control fingers. The charge output associated with the active openings in the control fingers is stabilized so that there is a substantially even distribution of charge output along the length of each control finger by providing first and second bleed holes associated with each of the control fingers, and closer to the gas input channel than are the active openings in the control fingers.

Abstract: A light emitting diode (LED) print head with a high-density print capability is achieved through an arrangement that produces high-density connections between an LED array and associated LED drivers. The LED array and LED drivers are mounted on a system board. A lens array that focuses light from the LED array onto a remote printing surface is attached to a lens array frame. Formed on at least one mounting leg of the lens array frame are metal contacts that correspond in number to the number of associated LED array and LED driver electrodes to be interconnected. When the lens array is mounted on the LED array and LED drivers, the metal contacts bridge the space between the associated LED and LED driver electrodes and thereby connect the associated electrodes of the LED array and the LED drivers in the same operation.

Abstract: A core conveyor system for electric motor manufacturing apparatus, including a core weighing station for improving the accuracy of stock measurement in manufacturing electric motor stator and rotor laminated stacks or cores from sheet stock. Stock is initially measured to determine a measured stack thickness. The weight of the manufactured stack is used to calculate the thickness of the stock material used. The calculated thickness is used to recalibrate the measured stock thickness. The weight of the stack, if not between a selected maximum and minimum values, determines if the height of the manufactured stack is acceptable. The core conveyor also include secondary stations for other core manufacturing operations.
