Abstract: A firing mechanism includes a hammer, an electrical solid-state full auto sear positioned to engage the hammer in a first electrical state and to disengage from the hammer in a second electrical state, and a controller connected to the electrical solid-state full auto sear for causing the electrical solid-state full auto sear to change from the first electrical state to the second electrical state. The controller may include circuitry for causing the electrical solid-state full auto sear to change from the first electrical state to the second electrical state at a predetermined rate, a predetermined number of times, or for a predetermined period of time. The hammer may include a retractable hammer bent for engagement with the electrical solid-state full auto sear, and the electrical solid-state full auto sear may include a piezoelectric device.

Abstract: A firing rate regulating mechanism for an automatic firearm is provided. The firearm, typically, operates according to the closed bolt principle in which a moving bolt carrier carries a bolt that locks each cartridge in the chamber prior to firing. A moving firing pin and a hammer are provided to strike the cartridge's primer subsequent to locking of the bolt. A time delay unit is provided and is movable between a compressed position and an expanded position. Movement to the compressed position occurs at a first, relatively rapid rate while movement to the expanded position occurs at a second slower rate. A linkage is provided that compresses the time delay unit as the bolt carrier moves routinely and the hammer is retained against forward movement to strike the firing pin until the time delay unit has moved back into an expanded position. According to one embodiment, the time delay unit can be interconnected with an automatic sear that normally engages the hammer.

Abstract: A firearm with a firing mechanism having a hammer, a trigger, a semi-automatic disconnector, an automatic sear, and an electro-mechanical movement mechanism for moving the automatic sear. The trigger and semi-automatic disconnector can be used to fire the firearm in a semi-automatic firing mode. The electro-mechanical movement mechanism can control release of the hammer by the automatic sear, but only after a first firing of the firearm by release of the hammer from a mechanical interlock with the trigger. The electro-mechanical movement mechanism has an actuator attached to a piezoelectric member. The piezoelectric member moves the actuator to move the automatic sear between a hammer holding position and a hammer release position.

Abstract: A fire rate control mechanism which allows an open bolt or closed bolt S.M.G. or L.M.G. to be, upon firing, momentarily arrested in a cocked condition and then to be released to fire another round after a predetermined and preset lapse of time.

Abstract: There is disclosed a method of producing a photograph of a mobile subject such as a vehicle, in which method a camera is mounted for linear translational movement along a support in a direction parallel with the path of movement of the subject. A motion transmitting operative connection is established between the subject and the camera such that for a linear translational displacement of the subject in said direction there will be a corresponding linear translational displacement of the camera in said direction along said support. The motion transmitting connection may comprise a mechanical connection e.g. via Bowden cable, or an electrical or electronic servo arrangement. To produce a photograph, the subject is displaced linearly in said one direction while making a photographic exposure in the camera, so that the period of the exposure lies within the period of corresponding movement of the camera along said support.
