Abstract: An actuator assembly includes an actuator drive source and a gust lock. The actuator drive source is operable to supply an actuator drive torque to drive a component. The gust lock is movable between a locked position, in which rotation of the drive source is prevented, and an unlocked position, in which rotation of the drive source is not prevented. The gust lock includes a lock shaft, a lock rotor, a lock motor, and a linear actuator. The lock shaft is rotatable with the drive source when the gust lock is in the unlocked position. The lock rotor is rotatable with the lock shaft. The lock motor is configured to supply a lock drive torque. The linear actuator is coupled to receive the lock drive torque and is configured, upon receipt of the lock drive torque, to move between an engaged position and a disengaged position.

Abstract: Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abstract: The load-bearing capacity of cylindrical shells of a composite fiber material that are at risk of buckling is determined by deriving improved reduction factors for analytical calculation of the design load. A load distribution head applies an axially acting force to a cylinder shell. A dent actuator dents the surface of the cylinder shell in a predetermined dent direction with a predetermined dent depth. A dent force is determined when a steadily increasing, axially acting force is applied to the cylinder shell by the load distribution head until a complete failure of the cylinder shell is detected. An analysis unit determines a dent depth from a data memory at which a dent force at a complete failure of the cylinder shell is at a maximum compared to dent forces of other dent depths.

Abstract: A device is configured to allow for the load-bearing capacity of cylindrical shells of a composite fiber material that are at risk of buckling to be determined. The device allows for deriving improved reduction factors for analytical calculation of the design load, which enables an improved approximation to the actual load-bearing capacity.

Abstract: The present invention provides for a composition comprising a silane having the formula: (R1)(R2)(R3)Si—R4—Si(R5)(R6)(R7) wherein R1, R2, R3, R5, and R6 are each independently selected from the group consisting of 1 to 6 monovalent hydrocarbon radicals, aryl, and a hydrocarbon group of 7 to 10 carbons containing an aryl group; R4 is a hydrocarbon group of 1 to 3 carbons; R7 comprises an anionic, cationic or zwitterionic substituent. The silanes of the present invention exhibit resistance to hydrolysis over a wide pH range.

Abstract: An accumulation conveyor has discrete zones which may be selectively actuated by pressurizing an interior cavity, urging diaphragms against spreaders which carry two spaced apart frame members. The frame members carry respective axle retainers which support the ends of axles on which pressure rollers are rotatably disposed. The pressure rollers urge the drive belt against the conveyor rollers.

Abstract: A radar system having a transmitter for transmitting a series of radio frequency (RF) pulses with sequential, incrementally changing carrier frequencies. A receiver receives energy from multiple scattering points of an object reflecting such transmitted RF pulses. The received energy from each one of such scattering points includes a series of radio frequency (RF) pulses corresponding to the transmitted pulses delayed in time, .tau., from the transmitted pulses an amount proportional to the range to such scattering point and shifted in frequency from the carrier frequency an amount proportional to the velocity of such scattering point. The receiver includes a heterodyning section, responsive to a range tracking error signal, .epsilon..sub.R, and a velocity tracking error signal, .DELTA..sub.VEL, for producing a series of pulsed signals for each one of the scattering points. Each one of the pulsed signals for any given scatterer sequentially changes in phase, .phi., at a rate, .DELTA..phi./.DELTA.

Abstract: A radar fuzing system for use in a guided missile wherein the system is tuned in accordance with the estimated intercept closing velocity to permit the use of narrower bandpass filters and thereby reduce the probability of detecting pulse repetition frequency lines and very low Doppler returns from chaff bundles.

Abstract: An improved radar receiver is shown to include a plurality of intermediate frequency and video frequency amplifiers, each one of such amplifiers being arranged to process received signals within a different range of amplitudes so that the overall dynamic range of such receiver may be equivalent to the dynamic range of a conventional radar receiver with automatic gain control.

Abstract: An improved monopulse receiver is shown to include an I.F. section wherein monopulse pairs of signals, meaning a sum and an elevation difference signal pair and a sum and an azimuth difference signal pair, are passed through paths arranged so that the signals making up each such pair are subjected to the same phase shift and amplification.
