Baling-Press.
Patent for baling-presses to prevent the inward-drawing or centripetal movement of the fiber in a press of the roller type (lines 96-97) by “disposed intermediate of the rollers and within the plane of the baling-cylinder for opposing resistance to the inward movement of the fiber and overcoming to a greater or less extent the tendency of the upper layer of cotton to form waves or billows in advance of the rollers.” (Page 1, lines 101-102, page 2, lines 1-6.) Illustration is included.

Borehole Seismic Monitoring of Injected CO2 at the Frio Site
As part of a small scale sequestration test (about 1500 tonsof CO2) in a saline aquifer, time-lapse borehole seismic surveys wereconducted to aid in characterization of subsurface CO2 distribution andmaterial property changes induced by the injected CO2. A VSP surveydemonstrated a large increase (about 75 percent) in seismic reflectivitydue to CO2 injection and allowed estimation of the spatial extent of CO2induced changes. A crosswell survey imaged a large seismic velocitydecrease (up to 500 m/s) within the injection interval and provided ahigh resolution image of this velocity change which maps the subsurfacedistribution of CO2 between two wells. Numerical modeling of the seismicresponse uses the crosswell measurements to show that this small CO2volume causes a large response in the seismic reflectivity. This resultdemonstrates that seismic detection of small CO2 volumes in salineaquifers is feasible and realistic.

Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area
Abstract: Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks are related to drainage area and percentage of impervious area. These relations which may be used to estimate the flood characteristics at ungaged sites, indicate that in the Houston metropolitan area, complete urbanization increases the magnitude of a 2-year flood nine times and increases the magnitude of a 50-year flood five times.
