Aircraft washrack wastes : their characteristics and treatment

Creator:: Evans, David Roland
Abstract:: Oils, greases, and grit which collect on an aircraft during flight are removed on the U. S. Air Force washracks using an alkaline, water-base cleaner. Waste-flows from these washracks may include in addition to free oils, emulsified oils, and alkaline, water-base cleaners several other constituents such as acid skin brightners,...

Analytical method for the prediction of reliability and maintainability based life-cycle labor costs

Creator:: Fitzpatrick, Mark W.
Abstract:: An analytical method for predicting life-cycle maintainability labor costs is developed. The purpose of the analytical method is to allow the evaluation of products, based on life-cycle labor cost, early in the design process. The Boeing 737-300/400/500 Bleed Air Control System is used as a test model, and the results...

Evaluation of remediation techniques for circular holes in the webs of wood I-joists

Creator:: Polocoser, Tiberiu
Abstract:: The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...

Analysis of single-channel maintenance costs

Creator:: Paul, Alexander
Abstract:: This thesis is a study of certain costs relevant to the repair of process line equipment. A specific production configuration is studied through computer simulation and statistics. The significance of the simulated costs are investigated and related to practical production problems. Costs relevant to the "permanent repair" of production equipment...

Sewer system rehabilitation and the effectiveness of chemical grouting

Creator:: Whitaker, Todd B.
Abstract:: The City of Salem, Oregon has an active sewer main chemical grouting program for the control of groundwater infiltration into the sewer collection system. The effectiveness of this chemical grouting program is evaluated by a comparison to other effective chemical grouting programs for control of inflow/infiltration (I/I). The importance of...

Development of an adhesive patch for polyethylene gas pipe

Creator:: Carbone, Cheryl B.
Abstract:: Polyethylene has been used extensively for natural gas transport since the mid-1970's. The pipeline system is sound and well-functioning, but there are some aspects of the system that could be improved. One of these is the repair method of leaking pipes. Presently if a natural gas pipe begins to leak,...

Investigation of the fatigue behavior of diagonally-cracked CRC deck-girders repaired with CFRP

Creator:: Williams, Grahme T.
Abstract:: Fiber reinforced polymers (FRP) are becoming more widely used for repair and strengthening of conventionally reinforced concrete (CRC) bridge members. Once installed, the repair may be exposed to millions of load cycles during service life. The anticipated life of FRP repairs for shear strengthening of bridge members under repeated service...

The testing and repair of polyethylene natural gas distribution pipe

Creator:: Hunt, John
Abstract:: With the dominance of polyethylene as the building material for America's natural gas distribution system and a growing demand for natural gas, there exists and ever increasing need for improved methods of repairing damaged natural gas distribution pipe. This paper serves as the ground work for a multi-part study seeking...

Squeeze-off & gel patch repair methods for polyethylene pipe in natural gas distribution lines

Creator:: Harris, Kevin E.
Abstract:: The natural gas industry has become essential in many areas in the United States. Currently there is over 37.5 million miles of natural gas distribution lines. A large majority of these lines are polyethylene pipes. With such a large percentage of polyethylene lines in use gas companies are continually looking...
