Abstract: A discharge excitation type pulse laser apparatus includes main discharge electrodes and and an auxiliary discharge electrode.  In order to make a voltage pulse applied to the auxiliary discharge electrode rise up steeply without incurring any appreciable time lag, a reactor connected in series to a first charging capacitor is constituted by a first saturable reactor 19 with a second saturable reactor being additionally inserted in series to a second charging capacitor.  After stray inductance and resistance components of a switch become minimum, inductance of the saturable reactor is first decreased, which is then followed by decreasing of inductance of the first saturable reactor.  Degree of steepness of the voltage rise-up for corona and main discharges can set at high values, respectively, whereby preionization is accelerated to allow the main discharge to occur uniformly.  The energy injected into the main discharge is increased.  Laser output power and oscillation efficiency are enhanced.

Patent CA-2167900-A1 (CA)
Inventor: GEE BERNARD
IPC: G01H17/00
Filed: 1996-01-23
Abstract: Method and apparatus for engine and rotary machine analysis provides a vibration sensor adapted to produce a plurality of superimposed waveforms corresponding to engine or machine operating parameters including rotational speed. The signals are transmitted by an RF transmitter/receiver system in analogue modulated form to a data capture and analytical function utilising a software sub-system in which a power spectral density plot is produced containing a signature characteristic of the engine or other machine under test. This signature is recognised by a signature detect algorithm which can recognise and trace the signature across the frequency spectrum covered by the apparatus so as to provide a continuous tachometric function not requiring the filtering-out or other removal of irrelevant data. A diagnostic function arises from detection of the presence of additional harmonic peaks within the signature. A capacitive coupling offers a simplified tachometric function based upon low voltage signals in the injector leads to a spark ignition engine.

Title: Non-contact characterization and inspection of materials using wideband air coupled ultrasound
Inventor: SCHINDEL DAVID W
IPC: G01N29/04
Filed: 1996-02-12
Abstract: A system for the non-contact inspection and characterization of an object in which wideband (40kHz to approximately 2MHz) air/gas coupled ultrasonic transducers are used.  The system of the present invention enables a single set of transducers to be used in an inspection/defect detection arrangement to characterize materials having a wide range of through-thickness, and other resonances.  For example, the through-thickness fundamental resonance of 11mm thick plywood is 44kHz, 723kHz for 2mm thick carbon fibre, and 1.47kHz for 0.75mm thick polystyrene, all of which are measurable in the same system.  The system is used in a method to characterize a defect by being able to operate at or near the resonant frequency of the normal material and at or near the resonant frequency of the material in a defect region to improve the accuracy of detecting specific types of defects including inclusions, material thinning, delamination and pitting by monitoring changes of various attributes (e.g. amplitude, frequency) of the detected output signal.  The system of the present invention can also be combined with laser or EMAT systems, where the means for generating ultrasonic vibrations in the object is a laser or EMAT and in pulse-echo arrangements in which a single wideband air-coupled transducer is used as the source and as the receiver/detector of ultrasound.
