Rapid-firing projectile launcher
A projectile launcher has a magazine of launching chambers for holding a plurality of projectiles at the launcher's front end. The projectiles are launchable by the delivery of a blast of compressed air through each chamber's respective air inlet. The air inlets are uniformly spaced in a substantially cylindrical array about the magazine. A piston with a handle is adjacent to the rear end of the launcher body. The piston has a longitudinal axis coaxial with the cylindrical array, and the piston is movable in back-stroke and fore-stroke motions along that axis for inhaling air into the launcher during the back-stroke and exhaling air from the launcher though one of said air inlets in blasts of compressed air during the fore-stroke. A rotatable diverter directs the blasts to one of the air inlets individually and sequentially upon successive backstroke and fore-stroke cycles of the piston.

An array coil for sensing signals in magnetic resonance experiments incorporates the traditional loop-butterfly array elements at spaced positions along an axis of the sample with additional stacked twisted loops and / or twisted butterfly elements. The twisted loop and twisted butterfly elements are centered along between the standard loop-butterfly array elements. The twisted array elements are naturally isolated from both the loop and butterfly. Alternatively, for a two dimensional mesh array of loop elements, additional twisted loop array elements are added with both longitudinal and transverse orientations, again centered between loop elements. The goal is to allow separation of loop and / or butterfly elements of linear (Spine), 2D planar arrays (Cardiac) or cylindrical arrays of curved array elements (Head), for improved parallel MRI capabilities such as the SENSE or SMASH techniques, but to recover the SNR lost in between the elements and improve the g-factor of the total array with additional orthogonal array elements.

InactiveUS20120175985A1Minimize currentPower Loss MinimizationEngine componentsMechanical energy handlingMagnetic bearingFlywheel energy storage
An axial stabilizer for the rotor of a magnetic bearing provides external control of stiffness through switching in external inductances. External control also allows the stabilizer to become a part of a passive / active magnetic bearing system that requires no external source of power and no position sensor. Stabilizers for displacements transverse to the axis of rotation are provided that require only a single cylindrical Halbach array in its operation, and thus are especially suited for use in high rotation speed applications, such as flywheel energy storage systems. The elimination of the need of an inner cylindrical array solves the difficult mechanical problem of supplying support against centrifugal forces for the magnets of that array. Compensation is provided for the temperature variation of the strength of the magnetic fields of the permanent magnets in the levitating magnet arrays.
