Abstract: Assembly for repelling birds from a selected area and method of making it. A rotor is assembled from a plurality of identical fin panels and rotatably mounted on a supporting pole within the selected area. Graphic designs comprising bird scaring holographic and/or diffractive images may be placed on the pole and/or rotor to simulate movement even when the rotor is stationary. The fin panels may be transparent and reflective to project light beams between and away from rotor surfaces. Outwardly projecting fin segments and a rotor barrel with vents are responsive to wind currents to rotate the rotor and generate bird repelling noises and visual effects.

Abstract: A phone case having a bottom wall, opposing side walls, and mouth and ear end walls that form a pocket with an opening having a rim for extending from ear to mouth and around the mouth to hide it from view and to muffle and block beyond the case words spoken into a phone nested therein. A sidewall portion of the rim may have a curved shape conforming generally to the contour of a human face from ear to mouth, and the pocket walls may be made of a flexible, sound absorbing material so that the rim of the opening is sufficiently deformable to conform substantially to the ear to mouth contour and form a sound seal when pressed against a human face. The ear end wall may form an ear portion of the rim for placement over an ear lobe to reduce interfering external noise.

Abstract: The MRI rf coil known as the balanced high-pass-weighted hybrid birdcage is modified to obtain two homogeneous degenerate resonances, capable of generating circular polarization at widely separated frequencies, by including inductors in parallel with the ring (high-pass) tuning capacitors such that their isolated parallel resonant frequency is greater than the desired low-frequency (LF) homogeneous resonance and not greater than 10% more than the desired high-frequency (HF) homogeneous resonance. The coil is advantageous for the frequency-diameter product range of 10 to 60 MHz-m. The coil is preferably balanced at both frequencies such that the electric potentials vanish on the central axial plane at both the LF and HF homogeneous modes. Additional parasitic-mode-shifting reactive elements, either capacitors or inductors, may be added between adjacent rungs near their ends, and the rungs may each consist of two parallel bands shorted together at their ends, as in the Crozier birdcage.

Abstract: A material having a permanent external diametrical electric field is included within an NMR MAS spinner. Such materials include ferroelectret porous films, in which the electric polarization arises from opposite mono-polar charges on separated surfaces within a structured material containing voids. Rotation of electrically polarized material produces a time-dependent electric field, modulated at the rotational frequency, so that a simple antenna achieves high sensitivity and phase stability in spin rate detection. The electrically polarized material is also of sufficiently high resistivity that modulation of the external NMR polarizing magnetic field B0 is negligible.

Abstract: An MAS probe is disclosed for obtaining a substantial improvement in signal to noise (S/N) in triple-resonance high-resolution (HR) magic-angle-spinning (MAS) NMR of samples near room temperature (RT) in high-field magnets where the magnet's RT shim bore is greater than 60 mm. All critical circuit components, including the sample coils, are located along with the spinner assembly in a thermally insulated cold zone pressurized with helium gas. The spinner assembly attaches to a sealed, curved, rotor-loading tube to permit automatic sample change, and it is surrounded by a partially insulated jacket cooled with a cryogenic fluid, generally nitrogen gas. The MAS probe is also compatible with magic angle gradients, variable temperature operation, field locking, and commonly available closed-cycle cold fingers.

Abstract: An improved axial gas bearing for a gas-driven NMR MAS sample rotor is disclosed that utilizes inward flow with a low rotational component over a rotor conical end. A conical flow region is formed between the rotor conical end and a conical stator bearing surface such that the included angle defining the stator surface is not less than the included angle defining the rotor conical end. Gas is injected radially inward with a significant axial rearward component from a number of small holes at high velocity from the periphery into the conical flow region. Compared to the radial velocity components, the tangential flow components of the injected gas are small and preferably opposed to the direction of the rotor rotation.

Abstract: A method of making an assembly for repelling birds from a selected area, including forming fins and vents on a rotor and rotatably mounting the rotor on the distal end of a support member, the proximate end of which is adjusted to be fixed within the selected area. The fins and vents on the rotor arc responsive to wind currents to rotate the rotor and generate bird repelling noises and visual effects. The fins may include light reflective and/or other design indicia to enhance the visual effects. An electrical sound producing device may be mounted on the rotor for emitting the sound of a bird predator.

Abstract: A transverse rf saddle coil (30) for use in NMR is affixed in intimate thermal conract on one surface of a ceramic coilform (23) of high thermal conductivity. The probe is mostly for use with solid samples at high fields where the axis of the coilform is not alignedwith the main field. An orthogonal rf coil (1) is mounted in intimate thermal contact to the first saddle coil (30) via a ceramic spacer or coilform (2). The coilform is cooled by high-velocity gas flow and is also often associated with bearing exhaust gas from a high speed sample spinner. The two coils are tuned to different rf frequencies with circuits capable of supporting high rf currents. The rf coils (30, 1) may be magnetically compensated and expansion controlled, and passive geometric compensation of magnetic susceptibility effects from a sample spinner stator may also be incorporated. Novel coil mounting techniques, including metallurgical bonds to ceramics and capturing by dielectric clam-shells, are also disclosed.
