  • Patent number: 6926227
    Abstract: Pulse integration is utilized on board an optically guided missile or other ordinance device used as a part of a target designation system for extending the lock-on range of the missile by approximately 18%, when a double pulse laser is utilized to illuminate and designate the target. Pulse integration is accomplished with a recirculating delay unit which superimposes the first pulse on the second pulse, such that while the pulses add coherently, noise does not add in phase. The pulse integration technique therefore enhances the signal-to-noise ratio when the missile is at the outer limits of its operating range. When the missile is sufficiently close to the target, doublet decoding is actuated to offer countermeasure resistance. At this point, pulse integration may proceed in lieu of doublet decoding or may be dispensed with in view of the increased signal-to-noise ratio due to the close range of the missile to the target.

  • Patent number: 4223649
    Abstract: A motor brake control system for use on a motor having a motor brake retarder and a throttle fuel control is designed to respond to manual selection for sequentially retarding the selected cylinders in the motor. A transducer for sensing the speed of the motor is provided for generating a series of output pulses which access a high RPM detector and a low RPM detector. In the event that the motor exceeds a predetermined high RPM value, the brake control system activates all of the retarders to fully brake the motor. In the event that the brake retarders are on, either fully or partially, and the motor drops below a predetermined low RPM value, the brake retarders are released. Provision is made to prevent retardation of the motor as long as the throttle of the motor is being activated and retardation is further prevented after deactivation of the throttle until the fuel in the fuel delivery system has been consumed.

  • Patent number: 4219170
    Abstract: A weapon system using a line of sight guidance system is provided with a missile containing two symmetrically located optical receivers. Information contained in a beam into which a missile is launched is used by the two receivers and associated processor means to derive roll position for the missile. Because the roll signal is derived electronically, mechanical means for determining roll position of the missile in the form of a conventional roll gyro, for example, may be eliminated. Elimination of the mechanical roll gyro from the missile permits much higher launch accelerations than are realistically feasible with missile control systems employing mechanically derived roll data. A processor located in the missile receives its signals from the pair of optical receivers. The processor uses the data from the first receiver to derive the position error of the missile relative to beam center.

  • Patent number: 4217862
    Abstract: Diesel fuel injection system in which a standing high-pressure wave is maintained in the common rail and which utilizes injectors which function as gates or valves. Electronic controls sensitive to engine demands based on speed and load electronically control the injectors to vary both moment and duration of fuel injection time. Input signals, as determined by engine speed by way of the distributor, vary the injection timing according to an advance curve at the distributor correlated to piston position. Duration of the injection cycle (quantity of fuel injected) is controlled electronically and variably in relation to throttle position.

  • Patent number: 4204485
    Abstract: In the art of motor fuel carburetion where conventional carburetors are employed to mix and prepare the fuel/air mixture for introduction into the combustion chamber of internal combustion engines, and particularly where gasoline is used as fuel, the liquid fuel is sucked, or aspirated out of the provided discharge opening by the current of intake air as it flows past this opening, thereby presumably mixing and preparing the fuel/air charge.In this invention the method of mixing liquid fuel with air employs a liquid fuel delivery spray valve which is so located as to spray liquid fuel upon an electrically heated metal plate which instantly converts the fuel from its liquid state into vapor form; a water delivery spray valve which is so located in similar fashion as the fuel delivery valve described above, to moderate the explosive violence of high octane fuel in the combustion chamber of internal combustion engines; and an electrically heated porous screen to atomize the fuel/air/steam mixture charge.

  • Patent number: 4196688
    Abstract: Minesweep gear is suspended from an aircraft to be a selected height above the surface of the water for deployment and the sweep gear is selectively stowed within the container so that the sweep gear is selectively sequentially deployed with the sweep equipment which is to assume a position farthest from the towing aircraft being deployed first and the sweep equipment which is to assume a position closest to the towing aircraft being deployed last. The sweep lead wire is connected to the aircraft towing cable and, by remote control from the aircraft, the sweep gear can be so selectively deployed and thereafter towed by the aircraft, the container being jettisoned once the gear is deployed and the sweeping gear being jettisoned at the end of the sweeping operation.

  • Patent number: 4195799
    Abstract: A method for guiding a flying vehicle having a light receiver by directing a spirally scanning beam at the light receiver. A repetition reference time of the scanning of the light beam is stored in the flying vehicle before it is launched. After the flying vehicle has been launched the radiation angle of the spirally scanning light beam is controlled according to the lapse of time after launching of the flying vehicle so as to maintain a scanning area of the scanning light beam on the light receiver constant. In flight, the flying vehicle is guided so as to be on the center of the light beam according to information on a displacement of the flying vehicle from the center of the light beam and information on a displacement angle from a reference axis of the light beam determined from a period of time during which the light receiver receives the light beam.

  • Patent number: 4195608
    Abstract: A fuel supply system for engines having a carburetor which has a float chamber and a vapor bleed passage connected to the float chamber, wherein a part of a fuel supply passage means for supplying fuel from a fuel tank to the carburetor traverses through the float chamber so that the fuel flowing through the fuel supply passage means absorbs heat from the fuel contained in the float chamber. The fuel entering into the float chamber releases volatile light components as vapor towards the vapor bleed passage while the liquid fuel contained in the float chamber becomes a more stable liquid due to the release of volatile components and the cooling effected by heat exchange with the fuel flowing through the fuel supply passage means.

  • Patent number: 4183664
    Abstract: Various embodiments of optical apparatus incorporating a foraminous plate to define a field of view are disclosed. In a first embodiment, the foramina in a foraminous plate are cylindrical with the field of view defined by the ratio of the diameter of each foramen to the thickness of the foraminous plate. The presence, or absence, of a target within the field of view is determined by the electrical signal out of a photodetector actuated by light passing through the foramina. In particular, embodiments illustrating the use of the disclosed optical apparatus as a sensor in a guided missile, the foraminous plate and photodetector are movably mounted in such a missile to allow either bearing or range of a target to be determined.
