Abstract

Abstract 05-11-2010 SPES-139781737820746.txt The Artillery Reconnaissance Crest Assurance Monocular is a tool employed by reconnaissance officers, section commanders, detachment commanders and safety staff in the conduct of their duties on the gunline. The device works through the input of pre-determined QE data onto the numbered dial which is set to either low angle firing or high angle firing. The calibrated cam will apply the corresponding distance along an adjusting drive shaft to an inclined concave slope to tilt the mounting board which houses the aforementioned adjustment mechanisms allowing tilt to be applied to an internal ethanol-filled bell reservoir. The ethanol chamber generates an artificial horizon and exhibits angular tilts with respect to this horizon. The switch between the two trajectory methods of engagement occurs on the extreme far edge of the superior internal cam and the commencement of run for the inferior larger cam attuned to the same point of measurement, enabling an additional 600 mil application through the large cam disk articulation. An inverted gas-filled pendulum maintains horizontal plane freedom of movement within the ethanol chamber, driving the indicator shaft terminating in the reticular mirror display. The initial horizontal angular pendulum displacement transmits as an up or down vertical correction through a pivoted pathway to within the monocular tube by a mirror angled from within the scope lumen. once this progression of data input application is completed and the resultant angles of measurement applied, the user observes the ordered zone of fire based on a preset bearing centre of arc and lines up the indicator shaft termination marker with the identifiable correct angle of lay. If there are no crests in the visual field through the superimposed reticular baseline, then the position is suitable for gun emplacement. If the ordered elevation observed through the monocular corresponds with the angle of the gun barrel, the gun is safe - pending subsequent bearing confirmation. Page 1 H--F--] 7/-' F~~ure 3

Description

1 Patent No 2010241250 Amended Specification Description Specification Description The Artillery Reconnaissance Crest Assurance Monocular is a tool employed by reconnaissance officers, section commanders, detachment commanders and safety staff in the conduct of their duties on the gunline. In order for effective indirect fire to be employed, an assurance is required for each individual gun that any local crest issues or trajectory interference is recorded and/or mitigated through the wisely considered selection of the gun platform position during initial reconnaissance. Overcompensation for the crest clearance safety factor through inaccurate incline angle measurement decreases capability. The device negates the requirement to repeatedly mount into an already congested workspace of self-propelled Howitzers by achieving the same angle of elevation monitoring external to the hull, and acts as elevation confirmation redundancy in towed artillery pieces not modified with auxiliary mechanical elevation measurement. The device consists of a tilt-initiating mechanism including an expanding shell-shaped universal charge gradient dual-cam articulating with a spring-pressured roller shaft distal to a calibrated angular base ramp, an angular tare switch for low angle / high angle measurement (Fig 1), an internal mechanism linkage articulating mount, an inverted enclosed gas-filled pendulum within an inclinable ethanol chamber, a subsequent pivoting indicator beam identifiable within a reticular aperture reflection display (Fig 2), an eye-cupped tubular monocular scope with mil based crosshair reticle (Fig 3), a ruggedised tilt-initiator mechanism housing, a graduated Quadrant Elevation (QE) dial and a mirror (Fig 4). The device works through the input of pre-determined QE data onto the numbered dial which is set to either low angle firing or high angle firing. The calculated QE is derived from the vertical acute angle measured from the horizontal plane to the line of sight passing through the weapon or instrument and the target. This angle of sight is added to the vertical acute angle measured from the line of sight to the weapon bore axis. The QE measurement is then applied to the aforementioned numbered dial on the instrument capable of generating precise vertical angular requirements based off an artificial horizon. The QE measurement is applied to an external graduated dial connected to an internal cam system. The calibrated cam will apply the corresponding distance along an adjusting drive shaft to an inclined concave slope to tilt the mounting board which houses the aforementioned adjustment mechanisms allowing tilt to be applied to an internal ethanol-filled bell reservoir. The ethanol chamber generates an artificial horizon and exhibits angular tilts with respect to this horizon. The switch between the two trajectory methods of engagement occurs on the extreme far edge of the superior internal cam and the commencement of run for the inferior larger cam attuned to the same point of measurement, enabling an additional 600 mil application through the large cam disk articulation. An inverted gas-filled pendulum maintains horizontal plane freedom of movement within the ethanol chamber, driving the indicator shaft terminating in the reticular mirror display. The initial horizontal angular pendulum displacement transmits as an up or down vertical correction through a pivoted pathway to within the monocular tube by a mirror angled from within the scope lumen. Once this progression of data input application is completed and the resultant angles of measurement applied, the user observes the ordered zone of fire based on a preset bearing centre of arc and lines up the indicator shaft termination marker with the identifiable correct angle of lay. If there are no crests in the visual field through the superimposed reticular baseline, then the position is suitable for gun emplacement. If the ordered elevation observed through the monocular corresponds with the angle of the gun barrel, the gun is safe - pending subsequent bearing confirmation.
