  • Patent number: 5097742
    Abstract: An ammunition conveyor is equipped to accommodate projectiles and propellant in alternating carrier positions. Conveyor cross members or rungs carry retainers to engage the projectile and propellant canister bodies and provide lateral restraint preserving their vertical orientations in the carrier positions. The rungs also carry vertical restraints which project out into engaging relation with the projectiles and propellant canisters to preclude hazardous vertical movements during field transport of the magazine. The vertical restraints are structured to automatically accommodate projectiles and propellant canisters of different length dimensions.

  • Patent number: 5080209
    Abstract: To override the vehicle immobilizing effect of a failed automatic ratio controller in a hydromechanical transmission, the conventional manually shiftable range selector is loosely linked with a ratio arm while the latter is being stroked by the controller to vary hydrostatic output speed. Upon controller failure, the range selector is drivingly linked with the ratio arm, such that shifting movements of the range selector are translated into stroking movements of the ratio arm to provide manual control of vehicle propulsion. Safeguards are provided to ensure that conversion between the normal propulsion mode governed by the automatic ratio controller and the override propulsion mode manually governed by the vehicle operator is effected in a safe manner.

  • Patent number: 5074402
    Abstract: An extensible ammunition conveyor includes telescoping conveyor sections mounting pairs of laterally spaced sprockets adjacent the conveyor section ends. A pair of endless chains are trained about these sprockets in coextensive, transversely spaced relation with each chain having transversely lapping run portions extending along the telescoped end portions of the conveyor sections. The sprockets of each pair are mounted in angularly relation to provide an effectively V-shaped open trough for transversely confining cylindrical ammunition rounds during conveyance motivated by driving the chains in unison. Jointly braking and driving the chains in an appropriate direction produces powered extension and contraction of the conveyor.

  • Patent number: 5065662
    Abstract: In a firing mechanism for Gatling-type guns, separate safing and firing cams are located at a firing position coinciding with a notch in an annular safing ring against which cocking levers ride to maintain their firing pins in pre-cocked conditions. To safe the firing mechanism, the safing cam is positioned to bridge the notch and maintain the firing pins pre-cocked as they revolve through the firing position. When the mechanism is armed, a cocking ramp surface of the firing cam is then positioned to cam the cocking levers rearwardly, cocking their firing pins. Immediately thereafter, the cocking levers drop off a firing cam sear corner into the notch now exposed by the safing cam to successively fire off ammunition rounds.

  • Patent number: 5019952
    Abstract: In an AC to DC power conversion circuit including a boost inductor connected in series between a full-wave rectifier and a DC load, a switch is connected to selectively shunt boost inductor current from the load. Switch conduction is controlled by a pulse width modulator generating switching pulses at a high fixed frequency. The pulse widths are automatically varied as a function of boost inductor current, load voltage, and an ideal sinusoidal waveform derived from the AC input voltage to force the boost inductor current to closely conform to the ideal sinusoidal waveform and thus minimize harmonic distortion, while achieving load voltage regulation and near unity power factor.

  • Patent number: 4997412
    Abstract: An infinitely variable speed hydromechanical steering transmission includes a range-changing mechanism flanked by a pair of hydrostatic units which are commonly driven by a mechanical input to produce respective mechanical and hydrostatic outputs. These outputs are combined in left and right output planetary gear sets which are interconnected by a cross-shaft extending centrally through the range-changing mechanism and hydrostatic units. The range-changing mechanism includes a plurality of clutches and brakes that are selectively engaged in pairs to incrementally change the mechanical output speed on the cross-shaft and thus to operate the transmission in a plurality of forward and reverse speed ranges. Each range change is accomplished by a step change in the hydrostatic outputs.

  • Patent number: 4982650
    Abstract: An ammunition handling system is provided with a magazine consisting of a plurality of modular, highly portable magazine packs which are readily installed in a mechanized support frame. The magazine packs contain separate ammunition conveyors commonly driven from the frame. Guides are positioned to effect direct transfers of ammunition rounds between conveyors of adjacent ammunition packs and thus to establish linear linkless ammunition round movement along a serpentine path leading to a magazine exit and ultimately to a rapid-fire gun. Rearming the gun simply involves replacing empty magazine packs with magazine packs pre-loaded with live ammunition rounds.
