摘要： A system for decorticating at least one bone surface includes an elongated soft tissue protector, an elongated drive shaft and a cutter. The elongated soft tissue protector has a bore extending therethrough. The bore has a non-circular lateral cross-section, a maximum lateral extent and a minimum lateral extent. The cutter may be located on or near a distal end of the drive shaft. The cutter has a non-circular lateral cross-section, a maximum lateral extent and a minimum lateral extent. The maximum lateral extent of the cutter is greater than the minimum lateral extent of the bore but is no greater than the maximum lateral extent of the bore. The bore of the soft tissue protector is configured to slidably receive the cutter therethrough. Other systems and methods for decorticating at least one bone surface are also provided.

摘要： The burner block or tile in industrial furnaces is conventionally made of refractory ceramic material. Such refractories are susceptible to cracking from thermal shock if the temperature of the burner block fluctuates during use. The life of the burner block can be greatly improved by making it in two parts: a cavity bounding inner part made from a material more shock resistant than a conventional refractory and a conventional refractory outer part. Best results are obtained with a thin inner liner of recrystallized silicon carbide having a thermal conductivity of over 18 W/(m K) and a modulus of rupture of at least 120 MPa.
