 Fault Assessment of a Diesel Engine Using Vibration Measurements and Advanced Signal Processing $29.95 This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A469523. The abstract provided by the Pentagon follows: A Diesel Engine test cell was developed, which consisted of a Detroit Diesel 3-53 engine, a water brake dynamometer and an engine cycle analyzer. Extensive steady state and time resolved instrumentation were installed along with a highspeed data acquisition system to obtain cylinder pressure and engine vibration data. High frequency response accelerometers were mounted on the cylinder head assembly to measure phase resolved response relative to top dead center (TDC) on the first cylinder. Baseline vibration data were taken over a range of engine load and speed combinations. An engine fault was introduced by adjusting the timing on the first cylinder injector. The vibration signatures of the baseline engine and the induced fault engine were characterized using Joint Time Frequency Analysis. The fault condition was detected and localized.  Hubbell GF5252MIA Ground Fault Circuit Interrupter Receptacle $17.07 These UL Listed receptacles have been designed to protect people from line-to-ground electrical shock hazards which may develop from faulty appliance, tools or defective portable cords. If a ground fault does occur and the leakage level exceeds 4 to 6 milliamps, the GFCI unit quickly acts to protect the user by opening the circuit, thus interrupting the power supply and limiting the duration of any electrical shock. After tripping, the receptacle is easily reset by pushing a button on its face. A test button allows the user to test that the GFCI is in working order. Note: GFCI receptacles will not protect against overloads or short circuits. Hubbells GFCI receptacles can be mounted on any standard 212"(63.5) deep box. A feed-thru feature provides protection not only at that receptacle but also at any other receptacle located downstream from it on the same circuit.
