Abstract: An arming and safing system for a missile having an acceleration responsive mechanism for actuating a timing device upon launching to insure arming only after the passage of a predetermined period of time, and an omnidirectional impact switch for activating a dudding switch in case of missile impact at a distance less than a minimum safe distance from the launching vehicle.

Abstract: An arming system for a missile which prevents destruction of the missile side of a specified area. The missile may be launched from a submarine, and follow a water-air-trajectory, and includes a variable-range timer acting in conjunction with an impact detection system. The timer drives arming switches to the armed condition after a predetermined time, and then opens the switches after a second predetermined time, which establishes a maximum range for detonation of the missile warhead.

Abstract: A gating circuit for a missile guidance system having a capacitor for supplying the output signal together with a plurality of silicon controlled rectifiers for applying or removing a supply voltage to the capacitor.

Abstract: A guidance monitoring safety system for a guided missile having platform os and electromechanical integrators with inputs from a guidance information analyzer. The system monitors malfunctions resulting from erratic or unsafe missile flight either dudding the missile if any malfunctions are present or providing a safe-to-arm fuzing signal in the absence of malfunctions.

Abstract: A safety system for deterring a homing missile from attacking its launching ehicle whereby the launching vessel is enabled to alter the course and neutralize the detonator of the weapon.

Abstract: An underwater acoustic transmitter adapted to be released from a submerged ubmarine to float towards the surface of the water and explode a plurality of signalling charges at a predetermined depth in a predetermined time sequence.

Abstract: An underwater communication system capable of being delivered by a missile or detonating a plurality of charges in a timed sequence. The system includes a main power supply, decelerometer means, separation switch means for electrically interconnecting and energizing the decelerometer means and said main power supply upon receipt of an arming signal from the missile, thermal battery means, means coupled to said decelerometer means for deploying a parachute and for energizing the thermal battery means, timer means for releasing the explosive charges in a predetermined sequence and means couples to the thermal battery means for energizing the timer means.

Abstract: A deep water explosive echo ranging system capable of detecting high perfance submarines by using favorable acoustic paths available at deep depths. An umbrella hydrophone array is deployed from a sonobuoy to deep depths; an electrical subsystem transmits data from the hydrophone array to a transmitter housed in a surface float unit; a multichannel receiver and signal processing and display apparatus in an aircraft receives and processes radio data signals sent from sonobuoy transmitters; and an explosive underwater charge package is remotely triggered by a command generator in the aircraft.

Abstract: 1. A variable delay arming timer comprisingA cylindrical housing,A motor and gearing contained within said housing,A shaft coupled to said gearing to be rotated thereby at a predetermined e, said shaft being coaxial with said cylindrical housing,Cam means mounted on said shaft for rotation therewith,Snap-action switch means carried by said housing and controlled by said cam means, said snap-action switch means having at least one spring biased actuating rod controlled between a retracted switch open position to an advanced switch-closed position by means of said cams, said rod being carried by said housing and being arranged in parallel relationship to said shaft and radially displaced from said shaft by a distance greater than the radius of said cylindrical housing, andSwitch carrying discs surrounding said cylindrical housing in coaxial relation thereto, said discs carrying switch elements in position to be actuated by said actuating rods.

Abstract: A high density component assembly package for a missile including a pluray of circular bulkheads axially supported by rigid spacing members to form a cylindrical adaption kit. Electronic components are mounted on and/or between the bulkheads with the electrical interconnections therebetween accomplished by the use of flat printed cables wrapped around the periphery of the assembly.
