20090318922 | REAMER SPINDLE FOR MINIMALLY INVASIVE JOINT SURGERY - An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations. The adjustment is desirable in order to accommodate operating on the left or right side of the patient, standing behind or in-front of the patient, or the use of a different surgical approach. Further, adjustment is important to accommodate the differing needs of surgeons who are naturally left or right handed. | 12-24-2009 |
20100204702 | PRECISION ASSEMBLEABLE SURGICAL TOOL HANDLE - A precision adjustable surgical tool holder/driver is provided which is easily disassembled for cleaning and precisely reassembled. The holder/driver has a positionable handle allowing adjustment of the position of the handle about the spindle of the holder to enable the “handedness” of the holder to be changed in order to accommodate a user while operating from the left or right side of the patient, standing behind or in-front of the patient, or for use in different surgical methods. The holder/driver includes a “limited-play” capture mechanism, which connects the drive end of the housing to its locking sleeve via a limited-play locking device. The limited-play locking device utilizes a disengageable, precision fitted bayonet pin and seat combination in part to accomplish the precision reassembly feature of the present invention. | 08-12-2010 |

20150177696 | REGULATING DEVICE - The invention concerns a magnetic device for regulating the relative angular velocity of a wheel and of at least one magnetic dipole integral with an oscillating device, said wheel or said dipole being driven by a driving torque, said wheel including a periodic, ferromagnetic pole path which alternates according to a center angle and said at least one dipole being arranged to permit magnetic coupling with said ferromagnetic path and oscillation of said dipole at the natural frequency of the oscillating element during the relative motion of the wheel and of the magnetic dipole to regulate said relative angular velocity, said device being characterized in that said wheel further includes means for dissipating the kinetic energy of said at least one dipole when it moves away from said ferromagnetic path. | 06-25-2015 |
20150177697 | ANGULAR SPEED REGULATING DEVICE FOR A WHEEL SET IN A TIMEPIECE MOVEMENT INCLUDING A MAGNETIC ESCAPEMENT MECHANISM - The invention concerns a device for regulating the relative angular speed between a magnetic structure and a resonator magnetically coupled to each other and forming an oscillator which defines a magnetic escapement. The magnetic structure includes at least one annular magnetic path at least partially formed of a magnetic material and the resonator includes at least one element for magnetic coupling to the annular magnetic path, this coupling element being formed of a magnetic material having a physical parameter correlated to the magnetic potential energy of the oscillator. The radial dimension of the annular magnetic path is smaller than a corresponding dimension of the coupling element, and the magnetic material is arranged so that the physical parameter of said magnetic material gradually increases angularly or gradually decreases angularly in order to obtain an angularly extended magnetic potential energy area in each angular period of the annular magnetic path. | 06-25-2015 |
20150177698 | ANGULAR SPEED REGULATING DEVICE FOR A WHEEL SET IN A TIMEPIECE MOVEMENT INCLUDING A MAGNETIC ESCAPEMENT MECHANISM - The invention concerns a device for regulating the relative angular speed between a magnetic structure and a resonator magnetically coupled to each other and forming an oscillator which defines a magnetic escapement. The magnetic structure includes at least one annular magnetic path at least partially formed of a magnetic material of which one physical parameter is correlated to the magnetic potential energy of the oscillator, the magnetic material being arranged along the annular path so that the physical parameter varies angularly in a periodic manner. The annular path includes, in each angular period, an area of accumulation of magnetic potential energy in the oscillator, radially adjacent to an impulse area. The magnetic material, in each accumulation area, is arranged so that the physical parameter of said magnetic material gradually increases angularly or gradually decreases angularly. | 06-25-2015 |
20150234357 | TIMEPIECE ABLE TO INDICATE THE SUNRISE OR SUNSET ANYWHERE IN THE WORLD - The timepiece includes sunrise and sunset indicating means taking account of seasonal variations, said means include a sphere reproducing the terrestrial globe, a shell arranged concentrically to the sphere and arranged to demarcate one portion of the terrestrial globe where it is night from another portion where it is day by indicating the position of the earth's terminator. The sphere is arranged to be driven by the movement so as to rotate at the rate of one revolution per 24 hours about a first axis of rotation oriented parallel to the plane of the dial, and the shell is mounted to pivot about a second axis perpendicular to the plane of the dial. The sunrise and sunset indicating means also include an annual cam arranged to be driven in rotation by the movement at the rate of one revolution per year, the cam having a profile representative of the tilt of the sun relative to the equatorial plane. | 08-20-2015 |
20160026153 | TIMEPIECE CAPABLE OF INDICATING THE SUNRISE AND SUNSET AT EVERY POINT OF THE GLOBE - The timepiece comprises means for indicating the sunrise and sunset taking into account seasonal variations ( | 01-28-2016 |
20160098012 | TIMEPIECE ABLE TO INDICATE THE SUNRISE OR SUNSET ANYWHERE IN THE WORLD - The timepiece comprises means for indicating the sunrise and sunset taking account of seasonal variations. These means comprise a sphere reproducing the terrestrial globe, a shell arranged concentrically to the sphere and arranged to demarcate one portion of the terrestrial globe where it is night from another portion where it is day by indicating the position of the Earth's terminator. The shell can pivot about the globe on two axes perpendicular to each other. The shell is driven by the movement so as to rotate at a rate of one revolution per 24 hours about the polar axis. A disconnecting mechanism is controlled by an annual cam which has a profile representative of the tilt of the Sun with respect to the equatorial plane. The disconnecting mechanism controls the tilt of the shell about the axis by means of a drive shaft concentric to the polar axis. | 04-07-2016 |
