Abstract: Methods are taught for treating chronic wounds and skin and soft tissue infections with antibiotic tumescent injection. In such methods, the region of tumescent drug delivery is monitored and expanded by the infusate in order to be 2×-5× larger in area and volume in the region of the wound or infection, the drug in the infusate creates a tissue concentration greater than the MIC in the tumescent volume for selected period of time, and the high concentration has a residence lifetime in the tissue long enough to kill the bacteria. Typically, the methods are performed without the use of vasoconstrictors such as epinephrine and in a manner that avoids physical manipulation of the wound.

Abstract: A rotatable steering shaft (12) has a surface (93) that defines a tapered locking opening (92). A mounting member (14) receivable on the shaft (12) has a first locking pin passage (70). A locking pin (16) for securing the mounting member (14) to the shaft (12) has a first portion (100) receivable in the first locking pin passage (70) in the mounting member (14). The locking pin (16) also has a tapered end portion (104) receivable in the tapered locking opening (92) in the shaft to secure the mounting member to the shaft for rotation with the shaft.

Abstract: A smoke damper which includes a rectangular frame and blades mounted in the frame such moveable between a position in which all of the blades are essentially coplanar with adjacent edges of adjacent blades being contiguous one with another, and a position in which the blades are rotated 90 degrees from the previous position with individual blades in planes parallel one with another. At least one of the blades has a recess formed along the length of the blade surface proximate to an edge of the blade and an elastomeric gasket mechanically secured to the edge of the blade having the recess which extends part-way across the recess from the edge of the blade towards the blade central portion.

Abstract: A convective heat flow probe device is provided which measures heat flow and fluid flow magnitude in the formation surrounding a borehole. The probe comprises an elongate housing adapted to be lowered down into the borehole; a plurality of heaters extending along the probe for heating the formation surrounding the borehole; a plurality of temperature sensors arranged around the periphery of the probe for measuring the temperature of the surrounding formation after heating thereof by the heater elements. The temperature sensors and heater elements are mounted in a plurality of separate heater pads which are supported by the housing and which are adapted to be radially expanded into firm engagement with the walls of the borehole. The heat supplied by the heater elements and the temperatures measured by the temperature sensors are monitored and used in providing the desired measurements.
