  • Patent number: 4192070
    Abstract: An orthodontic device comprises means defining a passage for an arch wire and means defining a tension spring for bearing against the arch wire. The tension spring has a free end portion for bearing against the arch wire and is fixed at its other end relative to the rest of the device. The tension spring locks against the arch wire to prevent relative movement of the arch wire to the device toward the other end of the spring and yields to the arch wire to permit relative movement of the arch wire to the device toward the free end of the spring. The device may be used in combination with a conventional buccal tube or orthodontic bracket, being located mesially or distally thereof or integrated with the buccal tube or orthodontic bracket. The device may further comprise a member having a channel defined through it. The channel is of larger cross section than the cross section of the arch wire to permit free movement of the arch wire in the channel.

  • Patent number: 4141956
    Abstract: A cold sterilizer comprises a tray for containing a sterilant and instruments to be sterilized, a lid fitting over the tray, a timer for measuring the period for which the instruments are to be contained in the sterilant to effect sterilization and means for resetting the timer to its original setting for a sterilization upon lifting the lid from the tray during the sterilization. The sterilizer may further comprise means for locking the lid onto the tray and means operatively connecting the timer to the locking means so that the locking means is locked while the timer is timing a sterilization and the locking means unlocks when the period for which the timer is set has expired. There may also be provided means for manually overriding the timer and unlocking the locking means during a sterilization and for thereupon resetting the timer to its original setting for the sterilization.

  • Patent number: 4011696
    Abstract: A multiple-line soffit system for supporting wall and window coverings such as blinds or draperies. The system is constituted by a series of interlocked modules having planar faces which extend from the perimeter wall into the room area, the modules being supported from an overhead structure by hooks or other means. Each module serving as a supporting fixture for a window or wall covering is provided with a recessed channel having a narrow entrance defined by a fixed ledge and a gate spaced from the ledge to create a linear slit extending the full length of the module. The ledge and gate lie flush with the face of the module to provide a surface free of projections. The gate is adapted to swing inwardly to admit a head piece, control cords and rollers or whatever other hardware is entailed, whereby to install a covering, all that need be done is to lift the gate to permit insertion of the hardware into the channel, the gate then being returned to its normal position to entrap the hardware.
