A method of forming a grain pile by pushing grain into a buried insertion point. A screw conveyor grain at ground level from a receiving point to the buried insertion point. The screw conveyor creates a pile core at the insertion point and forcibly enlarges the pile core into a large pile against forces of natural resistance. Piles as large as 2,000,000 bushels can be formed by a conveyor having a drive motor of less than 50 horsepower. Grains of different properties may be formed into a pile and become blended as a consequence thereof.

Method of forming a grain pile

A non-scored ballot card having a detachable portion provided with a triangular opening for locking the ballot card in a voting position in a vote recorder. The triangular opening is configured for cooperation with a barricade having a generally triangular cross-section.

Non-scored ballot card

A punch-type vote recording device for use with a machine-readable non-scored ballot card has a card block mounted in fixed relation to a punch plate and means for biasing the foot of a ballot card against a registration surface on the card block. The arrangement as disclosed eliminates the requirement for high dimensional accuracy in registration pins on the vote recorder and accurately positioned registration apertures in ballot cards. The invention is disclosed in a vote recorder having a slidably received ballot holder comprising a punch plate spaced apart from a guide plate and a card block depending from the guide plate. The punch plate is disclosed as being provided with a series of die openings, each of which has a sharp upturned lip for cooperating with a stylus to shear and cut a precise machine readable hole in the ballot card.

Punch-type vote recording device

A jet drop copier utilizing a row of electrically scanned jets under multiplexed control of a row of side-by-side photosensing elements. An image of an original document is scanned across the row of photosensors, and the output signals from groups of adjacent photosensors are multiplexed to enable each such group to engage in time shared control of a single jet. The jets are directed toward a print receiving medium, which may be mounted on a rotating drum. Means are provided for causing image scanning movement and the movement of the print receiving medium to proceed in synchronism. A print head for producing the printing directs a row of jets toward a catcher and has a series of printing control electrodes for causing the jets to avoid the catcher on a selective basis. Sideward scanning of printing drops is produced by scanning electrodes comprising vertically spaced electrode elements. A scanning signal is applied to each of the elements with a phase shift corresponding to the time of drop flight from element to element.

Jet drop copier

An ink jet printer for depositing drops at print positions on the surface of a print receiving medium includes a print head means for generating a plurality of jet drop streams directed toward the print receiving medium, each drop in the jet drop streams being charged to one of a plurality of charge levels. A deflection means generates a static electrical deflection field extending through the print receiving medium in a direction non-parallel to the plurality of jet drop streams for deflecting charged drops in the streams to print positions on the print receiving medium. In a first embodiment, the deflection means includes a deflection electrode plate which is nonperpendicular with respect to the jet drop streams. In a second embodiment, a deflection electrode of bulk resistive material is provided.

Ink jet printer including external deflection field

An ink jet printer for selectively depositing drops from a plurality of jet drop streams along associated print lines on a moving print receiving medium includes a print head which generates a plurality of such streams arranged in one or more rows, which rows are inclined with respect to the direction of movement of the print receiving medium. The drops in the jet drop streams are selectively charged to a plurality of charge levels. Thereafter, the drops are deflected in a direction substantially perpendicular to the direction of movement of the print receiving medium into a plurality of print trajectories or, alternatively, into a catch trajectory. An apertured catch plate in one embodiment may be utilized with an inverted print head which prints upon the bottom of the print receiving medium.

Ink jet printer with inclined rows of jet drop streams

Jet drop copier with multiplex ability

An ink jet printer produces high resolution printing from continuously flowing, non-stimulated jets. The jets are produced from a common manifold by rows of staggered orifices, all being relatively small in diameter. Drop deflection is accomplished by laminated electrode assemblies which are activated at a lower frequency than the natural drop formation frequency, so that each printed spot on the printing substrate is covered with a fairly large number of relatively small drops.

Jet printer and electrode assembly therefor

A jet drop printer prints graphic information upon an oscillating printing medium. The printer has a row of jet forming nozzles which produce a row of spaced drop streams. The drops in the streams are selectively charged, deflected and caught, so that uncharged drops produce intelligible graphic information on the printing medium. The spacing between the jets is such that they cannot print contiguous traces upon an ordinary transported printing medium. Contiguous printing is accomplished by lateral oscillation of the printing medium. The oscillation of the printing medium causes each jet to be directed at a plurality of lateral printing positions on a sequential basis, and data representing printing information for the different printing positions is multiplexed into the drop switching system in synchronism with the oscillation of the printing medium. Oscillation of the printing medium may be accomplished by a web transport system including a cylindrical roller and an axially driven oscillator connected thereto. The roller has an internal cavity large in diameter at the midpoint of the roller and relatively small in diameter at the support points of the roller. This causes an axially varying roller cross-sectional area which reduces roller distortion at the relative high axial vibration frequency.
