  • Patent number: 6209171
    Abstract: Apparatus for use in mounting a door on an overhead track comprising a carriage assembly constructed and arranged to be moved horizontally along the track in such a way as to limit upward movement thereof, and a door mounted assembly constructed and arranged to be mounted on an upper edge of the door so as to be moved with the door. The door mounted assembly is movable with the door (1) into an initial position wherein a locking member on the carriage assembly is in an initial vertically aligned position with respect to a locking member receiving opening on the door mounted assembly and (2) from the initial position upwardly with a snap action into a locking position wherein the locking member is in a locking position within the opening.

  • Patent number: 6178794
    Abstract: A free-wheeling lock mechanism for operating a door latch includes a body, a handle, a lock and a split shaft having two halves rotationally connected together along the shaft axis. One half of the shaft is connected to the handle and one half extends from the body to operate the door latch. The two halves of the shaft may be coupled and uncoupled via a shaft lock movable perpendicular between locked and unlocked positions. In the unlocked position the shaft lock connects the two halves of the shaft to rotate together when the handle is turned. In the locked position the shaft lock disengages the two halves of the shaft to rotate separately and allow the handle to free-wheel without operating the door latch.

  • Patent number: 6101856
    Abstract: A free-wheeling lock mechanism for a cylindrical door lock includes inner and outer spindles directly connected to corresponding inner and outer lever handles, a latch retractor located between the spindles and a cylindrical outer cam located within the outer spindle. The outer cam has an ear on its perimeter that moves from a forward to a rearward position as the outer cam is rotated to operate the latch retractor. A cylindrical locking plug is located within the outer cam and has an outwardly projecting finger that connects and disconnects the outer cam from the outer spindle to lock and unlock the mechanism as the locking plug slides axially relative to the outer cam. In the unlocked position the finger projects outwardly through a slot in the outer cam into a longitudinally oriented portion of a T-shaped slot in the spindle. In the locked position the finger projects outwardly through the outer cam slot into a circumferential portion of the spindle slot.

  • Patent number: 5992195
    Abstract: A free-wheeling lever handle controller for operating a mortise lock provides free-wheeling functionality while maintaining the full operational characteristics of various mortise lock functions. A lock mode receiving mechanism connectable to the lock output is used to detect the unlocked and locked conditions of the mortise lock, and correspondingly engage and disengage the free-wheeling mechanism. The free-wheeling mechanism has a split shaft connected between a handle on the controller and a handle input on the mortise lock. The two halves of the shaft may be coupled and uncoupled via a shaft lock movable perpendicular between locked and unlocked positions. In the unlocked position the shaft lock connects the two halves of the shaft to rotate together when the handle is turned. In the locked position the shaft lock disengages the two halves of the shaft to rotate separately and allow the handle to free-wheel with operating the door latch.

  • Patent number: 5937238
    Abstract: Methods of recycling printer cartridges use special rail-type clips for reassembly of complementary halves of a printer cartridge, the clips comprising cutouts or gaps spaced along the length thereof which accommodate protrusions near the edges being joined. The invention allows for recovering these cartridges and avoiding the cost of discarding a fairly costly machine element while additionally avoiding the processing costs for rendering the cartridge into inert, non-polluting waste.

  • Patent number: 5862972
    Abstract: An endoscopic surgical stapling apparatus is disclosed. The apparatus comprises a frame and a generally elongated endoscopic section connected to the frame and extending distally therefrom. The endoscopic section includes a mechanism for storing a plurality of staples, a mechanism for advancing the staples for positioning adjacent body tissue and a mechanism for at least partially closing each staple. A low pressure pneumatic system disposed in the frame provides the forces to at least partially activate the staple advancing mechanism. The apparatus has particular application in attaching mesh to body tissue as in laparoscopic hernia repair.

  • Patent number: 5678870
    Abstract: A reversible mortise lock comprising a casing, a latch bolt and a pair of spindle hubs disposed within the casing. Each spindle hub is independently pivotable about a fixed axis and has a slot. The latch bolt moves from an extended position to a retracted position in response to pivotal movement of either spindle hub. The latch bolt is rotable to a first orientation and to a second orientation. The reversible mortise lock further comprises an interfering member disposed within and accessible from outside the casing. The interfering member has a portion thereof sized for insertion into the spindle hub slots. The interfering member is pivotable to a first position corresponding to the first orientation of the latch bolt that allows only one of the hubs to pivot and to a second position corresponding to the second orientation of the latch bolt that allows only the other hub to pivot. The interfering member is pivotable from outside the casing without disassembling the reversible mortise lock.

  • Patent number: 5637132
    Abstract: Lead-free metallurgy powder for use in manufacturing a shaped bronze part by powder metallurgy techniques which consists essentially of a substantially homogeneous blend of metal powders having about 90 parts copper, about 10 parts tin and an amount of bismuth in the range from an amount effective to improve the machinability of the shaped bronze part up to about 5% weight are disclosed. Lead-free metallurgy powder for use in manufacturing a shaped brass part by powder metallurgy techniques which consists essentially of a substantially homogeneous blend of metal powders about 70-90 parts copper, about 10-30 parts zinc and an amount of bismuth in the range from an amount effective to improve the machinability of the shaped brass part up to about 5% weight are also disclosed.

  • Patent number: 5454824
    Abstract: A novel surgical instrument suitable for insertion and assembly of surgical fasteners, such as multi-ring compression devices, for circular anastomosis of tubular or hollow organ tissue sections, including a body having means to support and align the rings, means for clamping the rings around the free ends of the tissue sections, means for coring away excess clamped tissue and the centers of the rings, separate means for releasing the clamped rings from the instrument and dwell means to delay releasing the rings until after the coring operation is complete. The dwell means consists of an external cup containing separate and coaxial elements for the coring means and the releasing means which are provided with a series of recesses and a plurality of shifter keys to separate the operation of coring from the separate operation of releasing the assembled multi-ring compression device from the instrument.
