Abstract: A cascade combination of magnetostatic delay line elements operating in different signal propagation modes for the purpose of achieving dispersion cancellation; magnetic bias control of the attained frequency-dependent delay and a magnetic bias field establishing apparatus for providing the tubular, laminar magnetic flux needed for backward volume wave operation of a magnetostatic delay element are also included.

Abstract: Digital apparatus for generating moving grates of stimulus modulated bar patterns is disclosed. The bar patterns are modulated according to sinusoidal or other mathematical relations and can be alternately displayed as color and/or intensity variations on the display screen. Multiple display images, operator control of grate movement, and the use of image processing apparatus are also incorporated.

Abstract: A solid fuel rocket burn rate control apparatus wherein grain preheating energy is supplied to the grain region just ahead of the regressing burn face by optical conductors such as fiber optic filaments that are buried in the grain and dispersed across the grain cross section. The optical conductors receive optical energy from one of several types of electrical-to-optical energy transducers such as a semiconductor laser or an incandescent source; the optical conductors promote coning burn action at the burn face of the rocket and allow control of the burn rate by electrically modified optical signals.

Abstract: An arrangement for conveniently changing the illumination in an aircraft cockpit or other enclosure to a spectrum compatible with night vision infrared equipment including provision for easy return to the original illumination source. Selected LED elements are employed in multiple element arrays using a tether connected package that can be excited directly from existing wiring in fixtures.

Abstract: A microwave gas discharge apparatus for use as a limiter or TR device or the like and employing a primary discharge arrangement which has a single resonator used for priming the discharge device and determining the priming energy frequency.

Abstract: A low aerodynamic drag structural link suitable for use within the housing of a turbofan jet engine; the link includes length adjustment capability, pivotal end mounting provision, maintained airstream orientation capability, low mass and jam nut length and orientation locking. Several variations in link construction including a single ball and socket arrangement, varying link cross-section along its longitudinal length and the use of fairing nose and tail inserts are disclosed.

Abstract: An ionizing radiation intensity dosimeter apparatus and method based on carrier recombination saturation times for irradiated PN junction semiconductor devices following termination of a radiation pulse. Normally-on quiescent condition, moderate radiation doses at relatively high dose rates, and a read-out arrangement employing gated burst counting are included.

Abstract: An image processing apparatus for aiding analysis of images through the introduction of additonal physically displaced image elements in complementary color which are generated by digital processing of original image elements. The added elements and original image are viewed stereoscopically on an electronic reconstructed image display.

Abstract: A drum winch apparatus having an alternating current motor and direct current operable clutch and brake coils together with a control circuit for energizing these member is disclosed. The control circuit includes alternating current switching of DC current flows, operator control of both reeling in and unreeling drum functions, and selected use of separate brake release and brake hold off coils with a combination of full wave and half wave energizing currents.

Abstract: A thick film device conductor arrangement suitable for making connections between a resiliently mounted element such as a surface acoustic delay line and adjacent thick film conductors and then with the device connecting pins. The thick film conductors include a double layer structure of differing noble metals each selected for desirable properties in designated areas of the device.

Abstract: A hybrid integrated circuit data acquisition channel apparatus employing an operational amplifier fed by a low current differential bipolar transistor preamplifier having separate feedback gain and signal gain determining elements and providing an amplified signal output to a sample and hold and analog-to-digital converter circuits. The disclosed apparatus operates with low energy and small space requirements and is capable of operation without the sample and hold circuit where the nature of the applied input signal permits.
