  • Patent number: 4408536
    Abstract: A method of separating and ejecting a re-entry body from a booster rocket thout tip-off by igniting a pair of diametrically opposed rockets attached to the base of the re-entry body which provide thrust at an angle, and then firing a plurality of pyrotechnically operated separation nut assemblies, with the attachment bolts being captured in bolt catcher assemblies, to separate the re-entry body from the booster rocket, the pair of rockets providing separation velocity and spin to the re-entry body.

  • Patent number: 4408329
    Abstract: A laser device for generating frequency-doubled laser pulses at maximum eciency. A laser rod is optically pumped to radiate unpolarized light at 1.064.mu. wavelength for transmission within a ring-type resonator defined by a flat mirror and a turning prism. The light from one end of the rod is linearly polarized by a beam splitter into two parallel beams of orthogonal components which are transmitted through an 0.532.mu. output mirror, a frequency doubler phase matched for one component, and a Q-switch, to the turning prism for return along the beam of the other component to the beamsplitter. The output mirror, doubler and Q-switch are substantially ineffective during the pumping cycle, and because the component beam axes are reversed, the light does not return to the rod for stimulating light emission. After peak level pumping, however, the Q-switch is biased to rotate each component one quarter wavelength and return the components to combine and reenter the rod for stimulated light emission.

  • Patent number: 4406059
    Abstract: A mechanical and electrical connection for a piezoelectric member of polyic material such as polyvinylidene fluoride, and method for forming such a connection. To form the connection, the piezoelectric member is first masked to prevent a preselected portion of its surface from being coated during subsequent coating operations. An electrically conductive member such as a lead wire or a solderable terminal is then attached to the nonmasked area of the piezoelectric member with adhesive such as epoxy. The masked piezoelectric member, the electrically conductive member, and (incidentally) the mask are then coated with a conductive coating such as sputtered gold to electrically connect the conductive member to the piezoelectric member. The mask can now be removed from the piezoelectric member if desired, although it can be left in place as a convenient vise.

  • Patent number: 4406947
    Abstract: A transportable calibration and storage device for use in calibrating radion dosimeters. The calibration device comprises a drum filled with a radiation attenuating material that may be solid, water, or water-extended solid. This material shields the radiation source that is retained in a safe position in the drum at all times. During the calibration cycle the radiation source may be moved to a low or high calibration position within the drum so as to allow calibration of the dosimeter with a known radiation intensity.

  • Patent number: 4404666
    Abstract: A quick deployment vehicle (QDV) for implanting a transponder or beacon on he ocean bottom in an upright position exposed for receiving or transmitting acoustic signals. The vehicle includes a ballistic body of separable fore and aft sections. The fore section includes a core mass for penetrating the ocean sediment, and the aft section includes a beacon for signal transmission. A predetermined interval after impact, as determined by a programmed deceleration profile stored in memory, the sections will separate. The sensed deceleration of the vehicle is compared at predetermined intervals to the stored profile, and when the sensed level is less than the stored level, a squib is fired to separate the two sections. The aft section penetrates and remains exposed above the sediment, while the fore section further penetrates into the ocean bottom.

  • Patent number: 4399764
    Abstract: Passive apparatus for absorbing the kinetic energy of a collision to prot an underwater structure from damage in a collision which includes a ring suspended by a ring support system so that the ring is positioned between the structure and the expected path of potentially impacting objects. The ring support system includes eight rigid rods which have one end coupled to one of four symmetrically disposed supporting pylons by spherical sleeve bushings and their other end coupled by spherical rod ends to one of four standoff members that are fixed to the top surface of the ring at equal intervals around its circumference. A shock absorber is coupled between each supporting pylon and the ring midway between standoff members by spherical rod ends. The dimensions of the rigid rods and their attachment points to the supporting pylon and the ring are chosen so that the ring may pivot on the rods against the resistance of the shock absorbers in response to an impact, but cannot strike the enclosed object.

  • Patent number: 4395951
    Abstract: An improved release apparatus, including an actuator device, a release dee and a firing device, releases the firing device in a water environment and not in an air environment when the actuator device is remotely actuated. When in a water environment, a predetermined gas pressure from the actuator device drives forward a pusher piston and valve sleeve arrangement, disposed in a water chamber of the release device, initially to close off lower entry/exit orifices in the water chamber by action of the valve sleeve, and then to compress an entrapped column of water to a predetermined water pressure sufficiently to cause shearing off of an annular lip of a ball lock piston thereby separating the firing device from the release device. When in an air environment, the pressure from a compressed entrapped air column is not sufficient to cause shearing off or folding down of the annular lip of the ball lock piston, and, accordingly, the release apparatus is safed.

  • Patent number: 4394579
    Abstract: In a system for isotope enrichment, a method and apparatus for separating atoms of one isotope type from an environment containing plural isotope types. Tunable lasers or laser systems are used to selectively pump atoms of the desired isotope to a metastable excited state several eV above the isotope atom ground state. A reduced ionization energy is then supplied to atoms of the metastable isotopes taking advantage of the longer lifetimes achieved. The resulting plasma created by ionizing atoms of the isotope in the metastable state is subjected to electromagnetic fields to separate atoms of the desired isotope.

  • Patent number: 4388588
    Abstract: Information about the plasma density profile in an aerodynamic flow field of plasma adjacent a supersonic space vehicle or test model is provided by a flush mountable plasma density profile probe device having at least three striplines embedded in and separated by a dielectric support member from a conducting ground plane therebelow. In operation, the device is affixed flush and conformally to the surface of the space vehicle or test model. The plasma density profile is determined from a plot of data points derived from sequential measurements, in the plasma flow field environment, of the conduction between a driven stripline and parallel flush embedded additional striplines in the order of the nearest stripline to the furtherest stripline from the driven stripline. Standard formulas can be applied to determine the data points.

  • Patent number: 4388598
    Abstract: A loss-of-phase-lock indicator circuit is described which detects an out-limit voltage, whether steady or transitory. A pair of comparators, one for the high limit and the other for the low limit, are inserted in series between the tuning voltage and the sweep feedback amplifier, and are dc-coupled to the peak detector in the failure circuit. Additionally, a "dither" voltage is added in series with the phase detector, which ac voltage is large enough to swing the tuning voltage between limits at the loop amplifier output, but small enough to produce little effect on the output during phase lock.
