Abstract: A deceleration device for a submunition unit includes a cartridge releasably attached to the submunition unit. A releasable package including at least one pocket is disposed in the cartridge and is connected to the cartridge by a packaging line. An auxiliary parachute and a rotation parachute are disposed in the cartridge, with at least the rotation parachute being accommodated in the at least one pocket of the releasable package and the auxiliary parachute being disposed in a pocket separate from the at least one pocket. The auxiliary parachute is connected to the cartridge and the rotation parachute is connected to the submunition unit. A deployment mechanism causes the auxiliary parachute to be deployed in advance of the rotation parachute after the cartridge is released from the submunition unit and the rotation parachute to be deployed after the cartridge is decelerated by the auxiliary parachute for decelerating the submunition unit.

Abstract: A lubricator (which may be of rail form, tilted on its side) for applying lubricant to a railroad wheel characterized by deep, elongated slots so arranged that lubricant is spread on the wheel in spaced segments during one half the wheel turn and also during the next half turn; the lubricant first applied to the wheel is re-transferred during the second full turn.

Abstract: A warhead orientation device and its use in a directional attack mine are disclosed. The device includes a warhead launchable in a "pop-up" mode from a launch tube. The launch tube and warhead have a cooperating pin and helical groove system which imparts spin to the warhead during ejection from the tube. A stationary "fly wheel" type mass is attached to the spinning warhead. A cooperating pin and straight groove system on the mass and tube prevent rotation of the mass during ejection. This combination of spinning warhead and decoupled stationary mass provide a stable platform in one axis. Thus, suitable sensors and firing mechanisms may be used to cause a directional firing mechanism in the warhead to fire in a selected direction after pop-up.
