Patent number: H571Abstract: The invention is directed to a simple attachment for a surgical bone cutt or osteotomy saw. The invention, consisting of a calibrated T-bar, saw blade holder assemblies, and cooling assemblies, permits two standard surgical saw blades to be attached in parallel to a nitrogen powered surgical reciprocating saw. Thus, a surgeon can make measured, parallel bone cuts in a single motion. The cooling assemblies, pivotally attached to the blade holder assemblies, permit water to be directed down and into the surgical site during the entire cutting operation thereby eliminating bone necrosis and reducing the risk of post-surgical bone morbidity.Type: GrantFiled: February 20, 1986Date of Patent: February 7, 1989Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Jeffrey O.

Patent number: H572Abstract: An optical analyzer (10) wherein a sample (19) of particulate matter, and particularly of organic matter, which has been collected on a quartz fiber filter (20) is placed in a combustion tube (11), and light from a light source (14) is passed through the sample (19). The temperature of the sample (19) is raised at a controlled rate and in a controlled atmosphere. The magnitude of the transmission of light through the sample (19) is detected (18) as the temperature is raised. A data processor (23), differentiator (28) and a two pen recorder (24) provide a chart of the optical transmission versus temperature and the rate of change of optical transmission versus temperature signatures (T and D) of the sample (19). These signatures provide information as to physical and chemical processes and a variety of quantitative and qualitative information about the sample (19).Type: GrantFiled: September 28, 1987Date of Patent: February 7, 1989Assignee: The United States of America as represented by the United States Department of EnergyInventor: Anthony D.
