Abstract: A method and apparatus for injecting a liquid through a liquid passage cocting a liquid chamber to an outlet in the vicinity of the entrance of a gun bore. The liquid is forced through the passage by a piston movable in the liquid chamber in response to the pressure of a gas generated in a propellant chamber by combustion of a propellant for propelling a projectile down the bore. Two pistons and two liquid chambers may be arranged opposite to each other in a common plane with the propellant chamber and the outlets of the liquid passages may be located substantially opposite to each other in a wall of the bore. Each liquid passage may be arranged to inject the liquid in a tangential direction relative to the longitudinal axis of the bore so that centrifugal forces spread the liquid as a film around the circumference of the bore. Valves may be provided to close the respective liquid passages in the absence of pressure in the liquid chambers.

A pair of upper joints (34, 36) provide attachment to the vehicle structure (10). A linking device (42) is disposed between the lower and upper joints, whereby the control arm transfers loads through the lower joint means into the link, which transfers the load into the upper joint and into the vehicle structure.

Abstract: A speed sensor for a ship, more particularly, a thin speed sensor which can be mounted in the hull of the ship and remain flush with the outer surface of the hull. The transducer assembly for the speed sensor is composed of two thin piezoelectric transducers mounted in a spacer plate that locates them in an exact position relative to each other. A baseplate and a coverplate are affixed by appropriate adhesive techniques to each side of the transducers to create a single transducer assembly. Holes through the baseplate and spacer plate permit electrical contact to each side of the transducers so that they may be stimulated to generate acoustic waves. The entire transducer assembly is significantly thinner than the hulls of most watercraft. Thus, a large hole completely through the hull is not necessary. Rather, a shallow recess approximately equal to the thickness of the transducer assembly is made in the hull to countersink the transducer assembly flush with the hull.

Each primer strip also has a plurality of laterally extending castellations including teeth and depressions that slide on a ledge within the track. The track of the loading device is of substantially the same width as the strip, such that the strip slides through the track. A primer delivery slot in the device delivers a primer into the track, and a pressure application device is positioned to press the primer into a target primer receptacle.

Abstract: Apparatus for generating a ring vortex which will damage the hull of the get vessel. The apparatus comprises a torpedo which is launched from an attack submarine in the direction of the target vessel. When the torpedo is at a predetermined position, the torpedo is detonated. Detonation of the torpedo results in the generation of a ring vortex. The ring vortex is directed toward the hull of the target vessel and will impact the hull of the target vessel with sufficient force to destroy or disable the target vessel. Positioned about the periphery of the torpedo are a plurality of necklace charges. The torpedo also has a central charge which is located near the front end of the torpedo. When detonated each necklace charge forms a ring of imploding gas bubbles which collapse inward. At a predetermined time period after the necklace charges are denoted, the main charge within the torpedo is denoted resulting in the generation of an expanding gas bubble which expands outwardly.

In the preferred embodiment, the secondarily launched connecter is actuated by current through the target when the projectile is in proximity to the impact surface of the target.

Abstract: An ammunition clip or magazine for a firearm including a self-contained system for sensing the amount of ammunition contained within the magazine and visually or audibly indicating that value to the user of the firearm. The counting and indicator system may be configured to display the number of rounds remaining in the magazine itself, or the number of rounds remaining in the firearm overall (the number of ammunition rounds in the magazine plus one round in the chamber of the firearm, if applicable), or it may be configured to simply indicate that the magazine is empty or that the number of rounds remaining in the magazine is below some other predetermined threshold. The magazine may be utilized in conjunction with any suitable firearm without modifying the firearm.

Abstract: A launch aircraft launches a bomb at a target and uses a radar to transmit a predefined waveform at the bomb and target. The bomb incorporates a transponder that frequency shifts the transmitted waveform and illuminates the target with a shifted waveform having a null at the center of its beam pattern. The initially transmitted waveform and frequency shifted waveform are reflected from the target and are received by the radar. The received signals are processed to generate a correction signal that is a function of the offset between the null of the frequency shifted waveform and the target location. The correction signal is transmitted to the bomb and is processed therein to correct the flight path of the bomb toward the target.
