Patent number: 6272995Abstract: A high precision electro-mechanical fuze mechanism for a munition such as a hand grenade. The fuze mechanism includes an electromagnetic signal generator having an armature, a permanent magnet, a coil and a magnetic impulse generator (MIG) member. The armature is preloaded during assembly through the use of a spring. Releasing an actuating lever of the grenade allows the armature to begin spinning and to dissipate the energy stored by the spring. This causes a current to be electromagnetically generated in the coil, which is transmitted to an electronic control circuit in the fuze mechanism. The electronic control circuit implements two time delays from two separate timers which each must time out before the control circuit can send an electric firing signal to an electric detonator. Movement of the armature also causes a simultaneous movement of a rotor, which moves a stab detonator into a position closely adjacent the electric detonator.Type: GrantFiled: September 14, 1999Date of Patent: August 14, 2001Assignee: KDI Precision Products, Inc.Inventors: William Marc Schmidt, James Arthur Hewlett, Patrick Dwayne McGregor, Ezra Stearns Waller, Donald Robert Helton

Patent number: 4415130Abstract: A missile system is disclosed which collects and stores energy during the early stages of flight of a missile at a time when the acceleration forces on the missile are the greatest and thereafter, regulates the stored energy to at least one mechanism on board the missile for operation thereof. More specifically, the missile system includes a main support housing section and a nose cone section which is slidably, mechanically interconnected to the housing section. During the early stages of flight, the nose cone section is caused to move with respect to the housing section under the induced acceleration of the missile. Means are provided on board the missile to collect and store the energy resulting from the acceleration induced movement of the nose cone section with respect to the housing section and to provide the stored energy in a regulated fashion to at least one mechanism disposed on the missile for operation thereof during the flight time of the missile.Type: GrantFiled: January 12, 1981Date of Patent: November 15, 1983Assignee: Westinghouse Electric Corp.Inventor: John H.

Patent number: 4341158Abstract: A timing system for providing a fuze function time for firing a fuze which s independent of power source rise time. A non-volatile counter is programmed with a count indictative of the function time, and is read out starting at missile take-off to fire the fuze upon completion of read out of the count. Inhibit circuitry is provided for automatically reducing the stored count during the setting operation and for subsequently inhibiting the reading out of the counter by a time corresponding to the reduction in the stored count. This time is selected to be greater than the largest expectable rise time of the fluidic generator power source, but no longer than is necessary.Type: GrantFiled: July 15, 1980Date of Patent: July 27, 1982Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Alan C.

Patent number: 4164186Abstract: A signaling device to be launched underwater having a fuze body and a protile containing pyrotechnic compositions. The pyrotechnic compositions are ignited by an electrical squib which is detonated by voltage from a sea water battery which is sealed from sea water until a valve opens to permit entry of water into the fuze. An open circuit is provided between the battery and leads of the squib and, in addition, the squib leads are shorted. The opening of a valve to permit entry of sea water into the fuze causes the short to be removed and closes the circuit between the battery and the squib.Type: GrantFiled: October 21, 1977Date of Patent: August 14, 1979Assignee: The United States of America as represented by the Secretary of the NavyInventors: Bobby D. Beatty, Russell D. Daniel, Billy J. Humerickhouse

Patent number: 4149467Abstract: An adjustable time fuse includes an electrolytic cell with the anode and cathode connectible in two circuits with opposite polarity and a battery connected in the circuits. One of the circuits causes an element of the electrolyte to be deposited on one of the electrodes to activate the cell and the other causes the same element to be removed from the electrode. When this element is completely removed, the internal resistance of the cell increases rapidly. This increase in resistance triggers a thyristor to allow a condenser to discharge through a primer to produce the desired action.Type: GrantFiled: September 12, 1972Date of Patent: April 17, 1979Assignee: Dynamit Nobel AktiengesellschaftInventors: Klaus-Heinz Fischer, Hans-Joachim Eickmann

Patent number: 4119038Abstract: A time-delay RC circuit, having a preselected time constant, is connected ross a reserve battery undergoing activation. The function of the circuit is to hold off the application of the load of a power utilization device until the battery is sufficiently activated. Since the drain rate of the time-delay circuit is very small, it does not retard activation via polarization as would be the case if the full load were draining the battery during activation. A first switching transistor is connected across the charging capacitor of the RC circuit and turns on when the time constant is reached. When the first switching transistor is turned on, it turns on a second switching transistor connected between the battery and the utilization device.Type: GrantFiled: May 13, 1977Date of Patent: October 10, 1978Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Floyd Allen, Asaf A.
