  • Solid state vibrational lasers using F-center/molecular-defect pairs in alkali halides
    Patent number: 4638485
    Abstract: Vibrational emission from molecular defects in ionic crystals can be realized by dilute diatomic molecular defects such as, e.g., CN.sup.- molecules in alkali halide crystals. After association of F-centers to the CN.sup.- molecules, forming a new F-center/molecular defect pair, the emission can be pumped by optical F-center excitation through electronic-vibrational coupling. Using this coupling mechanism, laser action in the near infrared wavelength region is obtained between vibrational energy levels of the molecules while pumping the F-center/molecule defect in the visible wavelength range. The laser crystals are prepared by additively coloring a CN.sup.- doped alkali halide crystal and exposing the colored crystal to light having a wavelength capable of being absorbed by the electronic F-center/molecule defect transition.

  • Torsion spring apparatus and method
    Patent number: 4588175
    Abstract: The present invention relates to a novel torsion spring apparatus and method wherein anchor loops are formed in the end coil of the torsion spring to permit anchoring the spring directly to the appropriate mounting bracket. The provision of anchor loops in the end coil of the torsion spring effectively eliminates the requirement for conventional mounting inserts for the torsion spring and simultaneously increases the effective length of the torsion spring or, alternatively, permits the torsion spring to be shortened by the number of coils that would be otherwise rendered ineffective by the presence of a prior art insert.

  • Comminution apparatus
    Patent number: 4487371
    Abstract: A novel comminution apparatus and method for comminuting a granular feed into a product having a predetermined particle size. The comminution apparatus includes a high-speed cutter member operating inside a screen enclosure having adjustable openings in the screen enclosure. A lever arm is used to adjust the relative openings between an inner screen and an outer screen of the screen enclosure with the size of the openings in the screen enclosure predetermining the particle size range passing therethrough. Rotation of the cutter member creates an air flow outwardly through the screen enclosure while an air recycle system directs the airflow across the outlet to a feed hopper to carry the particulate feed into contact with the cutter assembly.

  • Two pump-frequency-stimulated Brillouin scattering ring laser gyroscope
    Patent number: 4396290
    Abstract: An improved ring laser gyroscope is disclosed that uses two counterrotating beams separated in frequency by an amount that is large compared to lock-in thresholds. The two beams are heterodyned together to obtain a beat frequency whose magnitude is proportional to rotation rate. In the preferred embodiment, the gyroscope utilizes an optical fiber waveguide as the laser cavity. The two countercirculating beams are generated via the mechanism of stimulated Brillouin scattering within the cavity. The two Brillouin ring lasers are pumped by two beams derived from an external pump laser. The derived beams are shifted in frequency by acousto-optic modulators. Lock-in is eliminated at all rotation rates. Other error sources common to ring laser gyroscopes are eliminated or greatly reduced.

  • Process for obtaining products from tar sand
    Patent number: 4337143
    Abstract: A novel thermal process for recovering hydrocarbon and other products from tar sand. The process includes blending tar sand with a bitumen-rich concentrate while heating the same with a hot, burnt sand. The products are recovered by passing the combined feed through a fluidized bed and selectively controlling the temperature and residence times to obtain predetermined ratios of products. Coked sand residue from the fluidized bed is burned to produce the hot, burnt sand, a portion of which may be recycled to provide heat to the fluidized bed. Coked sand may also be recycled into a known, hot-water, caustic separation process where it synergistically improves the separation efficiency of the hot-water, caustic separation process.

  • Solar energy absorber apparatus and method
    Patent number: 4333448
    Abstract: An improved apparatus and method for absorbing solar energy, the apparatus providing a sealed envelope having a transparent upper panel with a solar energy absorbing panel thermally isolated against convective and conductive heat losses by a partial vacuum in the sealed envelope. The transparent panel has an upwardly extending curvilinear surface which increases its strength characteristics against the pressure differential between the ambient and the partial vacuum inside the envelope. Support structure is also provided in conjunction with the apparatus to place the periphery of the transparent panel under constriction to compensate for tensile stresses imposed thereon by the pressure differential. The inside surface of the transparent panel and the absorber panel are selectively coated with an infrared reflective surface to reflect and reduce losses of infrared radiation emitted by the absorber panel.
