  • Patent number: 4328461
    Abstract: Apparatus for measuring a high voltage electric field, such as may be used in simulating lightning strikes or the like on a test specimen, is disclosed. In general, a capacitive electric field sensor is disclosed which utilizes a pair of spaced conductors or electrodes and which is placed in the field to be measured. The conductors shield a device within the sensor which generates a signal responsive to the intensity of the electric field. This signal is transmitted to a remote data acquisition system by means of non-electrically conductive data transmission lines (e.g., fiber optic transmission lines) so as to electrically isolate the sensor and the data acquisition system whereby the sensor only minimally distorts or affects the field being measured thereby. A method for measuring high voltage electric fields is also disclosed.

  • Patent number: 4282090
    Abstract: A sifting or screening device includes inner and outer concentric screened enclosures which rotate about a common axis. An inlet is provided at one axial end of the inner enclosure and an outlet is provided at the opposite axial end of the enclosures for the material that was too large to pass through the openings defined by the screens. An inclined dead plate or baffle member is provided at the inlet to prevent material fed in through a chute from impinging directly on the screen material and a pressurized air system presents a pulsating curtain of air to disengage material which has become lodged in the screen. A novel support system includes a circular support surface at the inlet end which rides on a pair of bearings and a central axle coincident with the axis of rotation driven by a motor at the outlet end. The axis of rotation is caused to lie at a small angle to the horizontal so that material which will not pass through the screens will slowly fall toward the outlet end of the enclosures.

  • 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: 4218879
    Abstract: An overspeed protection system is provided which utilizes simplified construction for detecting overspeed conditions of a rotating device. In the preferred embodiment, a single up/down counter is employed in an overall sequence which includes a first time period during which the counter is counted up from a preselected value by a series of pulse representations of speed for the rotating device. After the expiration of the first time period of the sequence, the counter value is compared to an overspeed limit selected during the previous sequence. If that limit is exceeded, an overspeed condition is detected by the system. In a second time period of the overall sequence, the counter is down counted by the pulse representations of speed. After the expiration of the second predetermined time period of the sequence, the counter value is compared to the original preset value to determine the rate of change in device speed.

  • Patent number: 4130787
    Abstract: A system for monitoring a machine tool under automatic control is provided which uses the actual path of the tool in all directions of motion for comparison with a mathematically ideal path to detect tool error. Machine tool position is obtained from independent feedback devices on each axis of tool movement. The system monitors the machine control commands independently of a machine control command generating means, the machine control command generating means commonly bring a computer of a conventional type. Thus, a monitoring loop is placed about the entire machine tool, that loop being capable of detecting malfunction or mispositioning of the tool, as that tool operates under automatic control. An independent dynamic braking means enables the system of this invention to bring the machine to a stop without part scrappage in the event of a machine shut down, occurring for example, because of a power system failue, or mispositioning error detection.
