Title: Surgical method and apparatus for fusing adjacent bone structures
Inventor: RAY CHARLES D
IPC: A61F2/46
Filed: 1990-09-18
Granted: 2004-11-09
Abstract: A fusion cage (10) having an external thread (12) can be surgically inserted into a threaded bore extending laterally between the adjacent bony structures such as two vertebrae (94, 95) with the thread (12) penetrating into cancellous bone of each of the vertebrae (94, 95). The fusion cage (10) is easily screwed into place by hand without damage to the bony structures (94, 95). Cage (10) is then packed with a bone-growth-inducing substance such as cancellous bone. When a pair of such cages (10) are implanted between adjacent vertebrae (94, 95), patients have been able to sit without pain by the second or third day, much earlier than has been possible in prior spinal fusions except those involving steel plates and screws. Eventually, the ingrowth of bone through perforations (13) in the valley (14) of the thread (12) of the fusion cage (10) forms a permanent interconnection between the two bony structures (94, 95).

Title: Multi-stage storage case for cassettes or cassette blocks
Inventor: MURAZUMI TAKUYA
IPC: B01L99/00
Filed: 1992-10-09
Granted: 2000-08-01
Abstract: A plurality of U-sectioned shelf units are disconnectably mounted one upon another between a base unit and a top unit. A drawer, for accommodating cassettes or cassette blocks, is inserted into each shelf unit freely slidable therein. A projection is formed on the upper edge of the rear wall of the drawer which disengageably engages with the indented stoppers provided in the underside of the top unit and each shelf unit so that the drawer can be pulled out stepwise because of the projection being engaged with the indented stopper. It is convenient since the number of shelf units disconnectably connected is adjustable as necessary. Also, the drawer can be pulled out stepwise being stopped at any of the stoppers provided in the shelf unit, hence the drawer pulled out halfway is ensured against further sliding out of the shelf unit.

Granted: 1999-08-10
Abstract: A method and apparatus for supplying an inert gas under extreme pressure to a weldable air bag canister having a gas-charging opening in one end wall, and weld sealing the opening. The canister, and a composite welding head and weld ball supplying assembly, having a lower nose with a seal surrounding a ball dispensing opening therein, are relatively moved axially to seal off the opening in the canister end wall. Then, prior to pressurizing the assembly, an individual ball is presupplied through a passageway seal system to a ball delivery member inboard of the seals which axe provided in the welding head and weld ball supplying assembly.      Thereafter, the composite assembly is charged with gas under a heavy pressure measured in thousands of pounds per square inch, and a raiseable and lowerable welding electrode, carried by the assembly axially in alignment with the ball receiving chamber and ball dispensing opening, delivers welding current to melt collapse the ball to seal the opening. Finally, the electrode is moved back to retreated position and the assembly is depressurized.

Title: Waste aggregate mass density separator
Inventor: GEMMER BRADLEY KEITH
IPC: B07B1/00
Filed: 1993-04-21
Granted: 1997-10-21
Abstract: Apparatus and method are disclosed for separating and recovering the solid particle components of a waste aggregate using screening and air separation mechanisms.  Such an aggregate could be  log yard waste  comprising  soil,  wood and mineral particles.   The aggregate is first mechanically screened to produce a product of fine particles (the soil) and a plurality of sized streams, each comprised of similarly sized particles of different densities (the wood and mineral particles).  The sized streams are then separately but simultaneously introduced into an air separation device which comprises an upstanding funnel-like member forming an upwardly converging passage through which air is flowing.  The smallest sized stream of particles is fed into the passage at the lowest elevation, where a separation of light and heavier density particles occurs,  light particles moving upwards with the air, heavier falling downwards.  Medium and  larger  sized  streams  are  fed  at  respectively  higher elevations, where the air velocities are respectively higher, separation again occurring.   The inlet point for each stream entering the converging passage is selected to match the air velocity at that point with the desired separation result: heavier density particles to drop, lighter density particles to rise.  Two products are recovered from the funnel-like member, a  high  density product  (the  mineral  particles)  of  varying particle size from the base of the passage and a low density product (the wood particles) of varying particle size from the top.

Title: Vibration-resistant low nox burner
Inventor: LIFSHITS VLADIMIR
IPC: F23D14/58
Filed: 1994-05-26
Granted: 1999-09-21
Abstract: A low NOx burner (2) includes a primary air and fuel discharge assembly which, in turn, includes a burner plate (6) having a plurality of slots (32) from which fuel gas jets and combustion air are discharged.  The slots are arranged such that the width of the recirculation zones between adjacent slots substantially varies between the central region of the burner plate and its perimeter.  With this construction, the local ignition patterns vary such that local oscillations of flame front occur at different frequencies so that vibrations are greatly dampened and resonance problems in the furnace minimized or eliminated.   In applications where high excess air is not desirable, such as boiler applications, the burner is modified by providing a secondary fuel and flue gas injection assembly (80) to form a two stage burner (2').  In the preferred embodiment, the secondary injection assembly includes a plurality of discrete fuel and flue gas injection tubes (82, 94) arranged around the primary air and fuel gas discharge assembly (50).  The secondary fuel and flue gases are directed radially inward and downstream from the burner plate so that they mix with the combustion air entering through the burner plate slots (32) in a secondary combustion zone.  The resulting delay in the combustion of the secondary fuel gas and the need for heating the flue gas lowers the overall combustion temperature, which in turn reduces the NOx formation in the second or downstream combustion zone.

Title: Contoured tire building drum and method of building an extended mobility tire
Inventor: CONGER KENNETH DEAN
IPC: B29D30/24
Filed: 1994-04-13
Granted: 2005-03-29
Abstract: Tire components are assembled on a tire building drum by laying a first liner on a surface of the drum, positioning first sidewall inserts below the cylindrical surface of the drum and around the drum at insert locations spaced from each end of the drum, laying a first carcass ply around the drum, positioning second inserts over the first ply at the insert locations, laying a second carcass over the first ply and the second inserts, positioning beads at each end of the drum, expanding the drum to increase the diameter of the cylindrical surface of the drum and provide shoulders at each end of the drum, turning edges of the first ply and the second ply over each of the beads, positioning a belt and tread assembly around the second ply, and contracting the drum for removal of the assembled tire components from the drum.      The inserts are positioned in grooves extending radially inwardly in the outer surface of the building drum. The grooves enable thick inserts to be built into the tire sidewall while still maintaining a generally flat outer surface of the tire while on the building drum, thereby decreasing the possibility of air trapped between components of the uncured tire.
