A Light Transmission Model For Biological Materials, R. A. Cavaletto, Shrinivasa Upadhyaya, Michael O'Brien
A Light Transmission Model For Biological Materials, R. A. Cavaletto, Shrinivasa Upadhyaya, Michael O'Brien
BioResource and Agricultural Engineering
This paper describes a model to predict light transmission in biological materials. The model can be used for any shaped sample. Scattering and absorption coefficients are used in the model and may be varied throughout the sample, thus allowing both uniformly distributed and concentrated defects to be modelled.
Guarding Of Table Saws With Light Beams: The Light Guard Concept, R. A. Cavaletto, M. S. Kaminaka, C. M. Zahner
Guarding Of Table Saws With Light Beams: The Light Guard Concept, R. A. Cavaletto, M. S. Kaminaka, C. M. Zahner
BioResource and Agricultural Engineering
This paper describes a unique type of psychological safety guard for hazardous tools such as table saws, presses. and other tools with areas and components which are dangerous to human fingers, hands, and limbs. It is not a piece of hardware but rather a shalt of light which defines a danger zone around the saw blade or cutting area.
Method For Stemming Tomatoes, Henry F. Studer, R. A. Cavaletto, Gene Giacomelli
Method For Stemming Tomatoes, Henry F. Studer, R. A. Cavaletto, Gene Giacomelli
BioResource and Agricultural Engineering
Method and apparatus for de-stemming picked tomatoes. Each tomato is introduced into the upper end of a generally vertically disposed, open-ended, resilient, open-mesh fabric tube, a substantial portion of which approximates but is larger than the diameter of the tomato. The stem penetrates into and through the open mesh at some point, the open areas being somewhat larger than the stem, while the tomato continues to fall, thereby exerting a bending moment on the stem that snaps the stem from the fruit. The tomato, free from its stem, is discharged from a lower end of the tube.
Low Technology Recycling And Rdf System At The U.S. Facility, Subic Bay, Philippines, Samuel A. Vigil, Donald E. Brunner
Low Technology Recycling And Rdf System At The U.S. Facility, Subic Bay, Philippines, Samuel A. Vigil, Donald E. Brunner
Civil and Environmental Engineering
The U.S. Facility Subic Bay is located about 50 miles east of Manila, on the East China Sea. The Facility consists of seven major Naval installations. The Facility is essentially a large commercial/industrial complex. The Public Works Center (PWC) Subic Bay is the public works agency responsible for the collection and disposal of the solid waste produced by the facility. A portion of the solid waste is manually sorted and recycled. Although the present manual sorting and recycling system is effective, PWC Subic Bay feels that it can be improved. Therefore , the Naval Civil Engineering Laboratory (NCEL) was requested …
Performance And Economic Feasibility Of A Sludge/Wastepaper Gasifier System, N. W. Sorbo, George Tchobanoglous, John R. Goss, Samuel A. Vigil
Performance And Economic Feasibility Of A Sludge/Wastepaper Gasifier System, N. W. Sorbo, George Tchobanoglous, John R. Goss, Samuel A. Vigil
Civil and Environmental Engineering
Thermal gasification of densified sludge/wastepaper fuels has been shown to be technically feasible for the co-disposal of sludge and source-separated wastepaper. The performance and economic feasibility of a downdraft packed-bed gasifier system fueled with densified sludge/wastepaper and wastepaper fuels has been evaluated.
To assess the performance of the gasifier, a series of gasifier runs were conducted at various air input rates with the use of various densified fuels. In eight of the runs, a densified fuel consisting of 20 percent lagoon-dried sludge and 80 percent recycled wastepaper was used; in five runs, densified wastepaper cubes were used. Gaseous and particulate …
A Basic Computer Program For The Gaussian Equation For A Point Source, Harold M. Cota
A Basic Computer Program For The Gaussian Equation For A Point Source, Harold M. Cota
Civil and Environmental Engineering
Many readers now are using microcomputers in their work. The advantages of these inexpensive and powerful tools are being recognized by both industry and universities. Microcomputers can be used in lengthy calculations, simulations, data collection and handling, and word processing. Programming these computers can be done in numerous languages such as Basic, Fortran and Pascal. It is often possible to find commercial programs or software available to handle a given application. There are a growing number of programs published which are now in the public domain. Only a limited number of programs dealing with air pollution problems are available ready …
