Abstract: The present invention relates to decoys for heat-seeking missiles and methods of producing and using the same. The decoys axe designed to be kinematic or pseudo-kinematic, producing one or more infra-red radiation emitting clouds that give the appearance of a moving infra-red target in the airspace in which the decoy has been released.

Abstract: The present invention relates to munitions employed for training and tactical purposes. Specifically, the present invention relates to training munitions (e.g., training rounds) used with various weapons (e.g., grenade launchers), wherein each training round includes a projectile that contains a pyrophoric payload that is released into the environment and reacts with air, upon impact of the projectile with an impact site. The reaction of the pyrophoric payload with air creates a signal that can be observed from a distance, thereby marking the landing or impact site of the projectile after it has been fired from a weapon.

Abstract: The present invention is an improved vacuum collection bag for vacuum cleaners and other appliances. By employing an impermeable bag and an air-permeable particle separator together with a tight seal against a vacuum system dirt tube in place of a conventional paper bag filter, it has been determined that the vacuum cleaner bag can be reused and significantly improve the filtration performance of the vacuum system.

Abstract: A wet/dry vacuum cleaner in one commonly available configuration includes a canister having an interior region defining a chamber, a motor mounted on the canister, a filter mounted on the canister and disposed within the chamber, and an inlet fitting attached to the canister. The inlet fitting is positioned generally adjacent the filter which results in the flow of air or water carrying debris generally towards the filter. The present invention is directed to a deflector boot which is secured to the inlet fitting for deflecting the flow of air or water carrying debris away from the filter. The deflector boot includes a cylindrical wall having an open end at one end thereof and an end wall that encloses the opposite end of the cylindrical wall. The open end of the cylindrical wall is sized to fit snugly over the inlet fitting when attaching the boot to the fitting.

Abstract: The present invention is an improved method of employing a wet/dry vacuum cleaner for wet material pick-up. By employing a hydrophobic and air permeable filter material, such as an expanded polytetrafluoroethylene (PTFE), with a tight gasket around its edge in place of a conventional wet/dry vacuum filter, it has been determined that the filter can be retained in place at all times during operation, regardless of the material being collected.

Abstract: A disposable marker apparatus for use with low torque recorders includes a bifurcated body with two separate ink reservoirs in the first and second body segments interconnected by a connector segment. The connector segment includes an ink transmitting member. A stylus tube extends from the body. A pivot member is provided to engage an associate pivot support outwardly from said pen body. A substantial portion of the mass of the marker is below the connector segment and the pivot member. The result is a marker having a center of gravity below the pivot so that the swinging marker tends to stabilize after disturbance due to vibration or rapid marker excursion.

Abstract: Convenient disposable marker tip design minimizes marker passing distance and provides a constant width trace line independent of the angle at which the marker tip engages the writing surface. The marker tip comprises a nib shank, surrounding and supporting a nib having a partially spherical tip. The nib shank is shaped to provide maximum coverage of the nib surface and minimum passing distance between adjacent nib tips.

Abstract: Expendable case ammunition of the type which is expelled as a unit through the barrel of a firearm and whose case separates from contained projectiles in flight, comprises a body and a cap, and may include a separate projectile container. These parts are made of a deformable material such as plastic, and are snap-locked together. The body has an interior transverse wall separating a projectile chamber from a propellant chamber, which is enclosed by the imperforate cap to permit the use of loose propellant and to protect against contamination and accidental ignition. An anvil is integrally formed in the propellant chamber wall to cooperate with an internal primer and a firing pin which penetrates the cap. A diaphragm region of the cap is ruptured by initiation of the primer, and the cap remains attached to the body during ignition of the propellant and travel of the ammunition unit through the barrel of the firearm.

Abstract: A composite ammunition casing, especially for use in repeating firearms or guns in whose chambers a temperature gradient develops, from a maximum at the forward throat portion to a minimum at the rear breech portion. The casing includes a forward metallic member and a rear member formed of a material having a lower temperature resistance, such as plastic. The casing members have an interlocking junction at a point spaced along the firearm chamber at which the expected local temperature of the chamber drops to a level within the temperature resistance capability of the rear member. The interlocking junction is formed by surface interruptions in the wall of the forward member, into which the material of the rear member projects.

Abstract: A composite cartridge casing having a plurality of component parts, which may be of dissimilar materials such as metal and plastic, includes a tubular casing body formed with a mouth portion for receiving a projectile and with a breech portion which has a cylindrical interior wall extending forwardly from an opening in its base. An annular bridge insert member has a forward cup portion which is receivable through the base opening into the casing body, a rearward skirt portion of reduced diameter, and a frusto-conical central portion connecting the cup and skirt portions. After insertion of the bridge insert, the breech portion of the casing body is deformed and reduced to engage the frusto-conical and skirt portions, thereby securing the assembly and forming an extraction groove around the base of the casing. A head assembly is then attached to the base to complete the casing.

Abstract: 1. A dart type projectile having a bore size cylindrical portion of a len at least as long as the diameter thereof, a conical nose extending forwardly of said cylindrical portion and having a taper of substantially 16.degree., a rearwardly extending shaft, and four stabilizing fins having longitudinally extending peripheral edge portions longitudinally aligned with peripheral portions of said cylindrical portion, of an axial length at least that of said cylindrical portion, and of a width capable of supporting said projectile as the cylindrical portion leaves a smooth bore gun barrel, said shaft extending rearwardly from said cylindrical portion to said fins, the periphery of said fins and said cylindrical portion being concentric to within about one ten thousandth of an inch, said nose having a density substantially twice that of iron to reduce retardation to about one foot per second of velocity with an initial velocity of about 3,800 feet per second.
