Abstract: A device for pulling electrical cable through conduit having a rigid frame with two wheels mounted thereon for being moved in a wheelbarrow like fashion and having attached to the frame a motor for driving a torque converter and speed reduced which drive a shaft which is clutched and which has a reel of cable connected thereto in which a guide and support mechanism directs the cable to the reel and support the entire device in a fixed position relative to the conduit through which the cable is being pulled and in which the motor can be remotely controlled by a switch.

Abstract: This disclosure relates to countermeasure systems, particularly to systems for providing a protective cover against homing and/or fire control devices operating upon infrared, sonar, or microwave reflected energy or for confusing search and tracking devices, and more particularly to decoy rounds and their method of fabrication. The decoy rounds include at least one load of energy generating material, means for propelling the load, a burst charge for shattering the load, the burst charge being constructed so as to cause a line type explosion, and means for igniting the burst charge.

Abstract: This disclosure relates to countermeasure systems, particularly to systems for providing a protective cover against homing and/or fire control devices operating upon infrared, sonar, or microwave reflected energy or for confusing search and tracking devices, and more particularly to decoy rounds and their method of fabrication. The decoy rounds include at least one load of energy generating material, means for propelling the load, a burst charge for shattering the load, the burst charge being constructed so as to cause a line type explosion, and means for igniting the burst charge. The decoy rounds are fabricated by a process which includes a novel method of producing the line type explosion and includes a novel assembly operation which allows the round to be exploded in such a way that birdnesting of the decoy material is minimized.

Abstract: The disclosure broadly relates to a launcher system for providing a protective cover against homing devices operating upon infrared, sound navigation and ranging, and/or microwave-reflected energy. The launcher system is illustrated in one embodiment as a nine round portable system wherein the decoy rounds are selectively fired manually by nine pushbuttons located in the control box. The decoy rounds each contain an electric squib which simultaneously ignites both a lift charge and a time fuse. The lift charge propels the round from the launcher in a ballistic trajectory and the time fuse ignites a burst charge which disperses the payload at the optimum altitude for the type of round being used. Other embodiments of the system illustrate a ten round system which may also be utilized in multiples thereof, with the control therefor being located within the control section of a ship or the like and activated through an intervalometer.
