Abstract: A disintegrable projectile is disclosed which utilizes thermal energy obted from the conversion of the kinetic energy of the air moving past the projectile to cause its fragmentation. The projectile employs an air intake nozzle axially disposed in the nose portion of the projectile and a resonance tube located in the body portion of the projectile in thermal contact therewith. The resonance tube develops the thermal energy which is transmitted to the body portion to cause the fragmentation thereof. The projectile of the present invention is intended for use in gunnery training and practice conducted within limited size training and practice ranges, where civilian personnel and property may be in proximate location.

Abstract: An improved switch actuator, for safe and arm applications requiring utmost ependability in order to preclude a premature or false arming sequence, utilizes a plurality of simultaneous input signals from independently coded pneumatic, optical and electrical sources to drive a rotary switch. A rotary fluidic valving plate is used to decode non-uniform input optical signals into a uniform cyclical output pressure signal which is used to drive a fail-safe, reversible pneumatic gerotor type motor. A geneva mechanism is used to mechanically couple the prime mover to an output gear to activate a switch. Alternatively, an electrical switch may be incorporated within the housing of the actuator.

Abstract: An artillery shell is provided comprising two sections having complementary oupling members for connecting the sections together. The complementary coupling members include at least two locking assemblies which can be engaged to prevent relative axial movement of the coupled sections or disengaged to permit the disconnection of the sections. As a result, the sections can be connected and disconnected for different mission requirements and for inspection purposes.

Abstract: An improved buffer for small arm weapons utilizes a pair of fluid containing reciprocating chambers to attenuate recoil forces by limiting fluid flow in relation to chamber travel between the pair. In the second chamber of the pair a flow control element moves in the direction of a restricting member when the fluid pressure drop through the flow control element reaches a predetermined point. The flow restricting member limits fluid flow through the flow control element when the flow control element travels to a point proximate the flow restricting member. Fluid flow in the opposite direction is substantially unrestricted by the flow restricting members.

Abstract: A weapon is provided with means to buffer the recoil which is produced when the weapon is fired. The buffer includes a fluidic device having a first and a second chamber. During recoil, a compressive force is applied to the fluid in the first chamber and flow from the first chamber to the second chamber is restricted by a fluidic diode in relationship to the pressure differential between the first and second chamber. On counter recoil, the fluid flows from the second chamber to the first chamber in an essentially unrestricted manner. The level of flow restriction by the fluidic diode is greater at high pressure differentials than at low pressure differentials.

Abstract: A pair of contacting rolling spheres are disposed in a tubular housing inmediate a stationary cam element and a fluidically damped and lubricated movable cam-piston member. The cam-piston member provides an axial force of sufficient strength to restrain loosely stacked elements of a spin stabilized munition. The device has its longitudinal axis offset from the main spin axis of the munition in order to utilize centrifugal forces associated with spin to generate by cam action an axial thrust force of sufficient magnitude and proper direction to restrain slidable elements within the munition.

Abstract: A fluidic G sensor for monitoring the acceleration or deceleration of a mile includes a hollow cylinder containing an inertial mass, e.g., a piston, which is supported by a diaphragm pressurized by gas. The gas pressure is supplied from an external source and is metered into the diaphragm chamber through a fixed orifice. Gas is discharged from the chamber through two vent orifices, one fixed and the other variable. The fixed vent orifice represents the output load and leads to a fluidic Schmitt Trigger. The variable vent orifice is modulated by diaphragm motion and serves to control the pressure under the diaphragm as a function of acceleration of the piston. A dashpot formed between the piston and the upper closed end of the cylinder, which contains a small orifice open to ambient pressure, is employed to damp the oscillation of the piston and thereby stabilize the output pressure.

Abstract: The invention provides a novel dual safety fuze for a rocket-launched mine learing linear high explosive charge. The fuze comprises a tubular housing, having a forward section containing two booster charges for initiating the line charge, an intermediate section containing two electric delay detonators, a rotor containing two lead charges positioned between the forward and intermediate sections and a rearward section mounting two axial arming pins, which provide a first and second lock of the rotor in the safe position. A novel rotor spring assembly includes a rotatable shaft, whose one end is attached to a torsion spring for rotating the rotor and other end has a screw-like configuration, which is engaged by a fork-like driver mounted on the first arming pin.

Abstract: There is disclosed an improved locking assembly mounted on a door assembly f a SOC and including a plurality of segmented linear bolts peripherally-disposed about the door assembly for engaging cooperating latches mounted on the container body and operatively connected to handle assemblies for latching and unlatching the locking assembly to permit opening and closing of the door assembly of a SOC and wherein each handle assembly is provided with a key operated combination lock.
