Abstract: A composite plastic-glass frangible rotating band, for a spin launched prctile, has epoxy filled annular stress risers embedded within its inner wall. The composite rotating band is designed to be resistant to compressive forces exerted thereon while in the gun barrel, but to fragmentize when suddenly subjected to tensile stress impressed thereon when exiting from the muzzle of a gun.

Abstract: A fluidic logic circuit is used to control access to a secured area by receiving pneumatic signals from a fluidic signal input transducer determining whether or not specific coded input requirements have been met. When all inputs to the signal input transducer are correct the fluidic logic circuit applies fluidic signals to valving which in turn provides fluid power to pneumatically operated latching devices. When one or more incorrect inputs from the signal input transducer are received by the fluidic logic, a dual signal is initiated by the fluidic logic which shuts off the power supply valve and prevents opening of the pneumatic latch.

Abstract: A conjugate pair of self-aligning joints are formed in the peripheral edges f a relatively thick walled hemisphere which when brought together form a hermetically sealed ball shaped container. The interlocked joint utilizes oppositely disposed, grooved, deflecting flanges which nestle and lock one within the other. The hemispheres after being forcibly pushed together have an interlocked joint therein which resists inadvertent disassembly due to vibration or shock.

Abstract: A pneumatic transfer switching apparatus utilizes movable and stationary cs having ground, drilled, and grooved faces biasedly held against each other and in axial alignment to permit operation and repositioning of rotatably held scale cut-off pneumatic sensor elements, while maintaining continuation of pneumatic flow paths to the sensors without requiring the use of flexible pneumatic hoses.

Abstract: An electrically operated warhead enable switch utilizes a dual solenoid de mechanism in conjunction with a DC lock solenoid mechanism to sense a plurality of unique enable signals and in response thereto permits the driving of a differential which is mechanically coupled to a biased output shaft. The output shaft when rotated a specific number of degrees closes the terminals of a plurality of functioning switches and thereby allows the enabling of a missile's warhead circuitry.

Abstract: A high pressure vented toroidal shaped propellant chamber has an integrally ttached primer assembly which communicates therewith by a tubular spoke element. The vented propellant chamber is affixed to the rear end of a projectile. The propellant, when ignited, generates gases in the vented toroidal chamber providing the propulsion force needed to forcibly expel the projectile from a launcher. The caseless projectile attains a proper muzzle velocity without the use of a conventional cartridge case.

Abstract: A spring supported disc holder, having a plurality of discs affixed there is fixedly attached to the rear convex side of a plow member which is rotatably supported within a centrifuge basket. The disc holder assembly provides for the removal of a residual layer of explosive material at the same time that the plow member safely removes a main body of explosive accumulated material from the interior wall of the centrifuge basket.

Abstract: An improved pneumatic match utilizes a vented conically shaped nozzle flare ositioned in a downstream region of a convergent nozzle to permit the match to be used in applications where fast functioning time is a necessity and where the fluid activating medium comprises a low helium pressure source or only high pressure air.

Abstract: A canister cartridge projectile utilizes gun gas pressure, bled from the r of a projectile through flow control orifices in a sabot body to a piston contained therein, and set-back acceleration to sequentially eject a payload and a nose cone assembly. The nose cone assembly is attached to the sabot by a plurality of detent lugs which are unlocked on setback by the movement of a slidable ring. Two O-ring seals positioned between the sabot and the nose assembly and the sabot and the cartridge assembly provide moisture protection for the projectile interior and the cartridge propellant charge.

Abstract: A plurality of interlocking reinforced barrel shaped plastic torso fitting embers has a transparent vented plastic head piece threadedly connected thereto. The torso members are suspended and attached to the wearer by adjustable strapping. Compliant material is used intermediate the shock resisting members and the wearer to help position the armor on the wearer and to attenuate the transmission of blast shock waves from the armor to the wearer. The openings in the armor, to accommodate the wearer's appendages, are hermetically sealed by a lining made of rubber material. Air for breathing is brought into the helmet and exhausted therefrom by intake and exhaust check-valves which are actuated by the wearer's normal breathing.

The actuator comprises a housing which has a longitudinal bore communicating with a threaded end and a partially closed flanged end, a biased top spring operatively screwed to the threaded end, a biased stop spring pinned to the flange end, a collapsible column means axially positioned in said housing bore intermediate to the top spring and the stop spring, and a firing means, for actuating the munition when the column means collapses upon impact.

Abstract: A combined rocket container launcher utilizes a housing which is capable of ithstanding normal shipping forces and which can be easily installed on a carrier weapon without undergoing an unpack-load launcher procedure. The integrated container-launcher permits a plurality of rockets to be safely transported to the site of use and rapidly installed and fired as a unit with only a minimum number of mechanical operations and electrical connections.

Abstract: An electronic time opener and opener system is utilized for initiating the pening of a plurality of munition cannisters at an accurate settable time after ejection from a high speed aircraft. Analogue circuitry is used in the opener setter to measure the capacitance of an RC circuit of the electronic time opener, immediately prior to cannister ejection. Upon the basis of this pre-ejection measurement a proper voltage charge is generated to obtain sufficient energy to actuate a detonator in the munition at the proper time. The combined opener and opener setter system permit accurate tuning while using wide tolerance capacitance components in the electronic time opener.

Abstract: A test device is used in combination with two selectable resistors to indte when the pulse forming network voltage of a tank laser range finder system is properly adjusted. The test device utilizes a precision temperature compensated current source, an operational amplifier, and a comparator and a lamp driver circuit, electrically coupled intermediate a pulse forming network power supply and a receiver transmitter unit, to indicate overvoltage, undervoltage and null conditions.

Abstract: A self-sealing fluidic explosive initiator utilizes a tapered sliding inner leeve, having a nozzle element, resonance tube and an explosive charge proximately disposed adjacent the resonance tube, to mate with a fitting sleeve for terminating a gas supply flow to the nozzle, and for containing the products of explosion of the initiator upon activation of the explosive charge. The initiation of the explosive charge is used to move a piston cutter valve.

Abstract: An aircraft munition dispensing cannister device utilizes a tubularly sha central housing piston member, having a spline engagement dog thereon, to releasably engage a supporting helically splined mast. Spin is given to the cannister when the piston cannister is forcibly detached from the mast by expanding gases which are released from an explosive cartridge and are trapped intermediate the mast and the central housing member. Hot cartridge gases are vented into a passageway within the cannister to initiate a pyrotechnic delay train which subsequently actuates an explosive charge which aids in blowing apart the cannister sides and scattering the munitions.

Abstract: A ball having a variable volume cavity therein is integrally machined on a haft which is rotatably supported between two bearings. The ball is maintained in intimate sliding contact with a hopper seal at all times. An air-operated actuator is used to rotate the shaft and ball 180.degree. to place the ball in its load and unload positions. The variable volume cavity allows volumetric adjustments to be safely made even when dispensing sensitive explosive powders, such as lead azide. A hopper containing the explosive powder supply is bearing-mounted above the ball and funnel on two vertical shafts. The weight of the hopper maintains intimate contact between an electrically conductive plastic seal insert in the bottom of the hopper and the surface of the ball on which it rests and prevents leakage of powder during fill and discharge of the ball cavity.

Abstract: A tilt testing device simultaneously measures the angle of tilt of a plurty of nozzles of a multi-nozzle rocket motor and the direction in which each nozzle is tilted. A programable calculator computes the composite effect that such nozzle tilt would have on spin, pitch and yaw of a missile in flight. The calculator displays the numerical value of the composite effect, indicates the acceptance or rejection of the inspected work piece, and, when desired, prints a record of the resultant calculations. The tilt tester utilizes an electromechanical-pneumatic combination to lower a plurality of alignment determining probes into the nozzles while the work piece is clamped against a reference surface. An indexing rotating sensor assembly scans each probe for its angle of tilt and sends signals to the calculator for interpretation and display.

Abstract: Internally fragmented shot is stage released from a cartridge so as to yi a double cone-pattern of shot. The cartridge utilizes a two step fragment release design which expels fragments at two separate points on the projectile trajectory. Parasitic initiation of separate delay trains cause expulsion of fragmented shot so that fragment patterns achieved by each group of fragments yield a dense fragment pattern from point of release over a wider angle. Higher cartridge lethality is attained because an initial fragment pattern overlaps and includes a second fragment pattern. Ability of the design to initiate release of fragments at alternate positions in the projectile's trajectory results in an extended range "shot" capability.
