Abstract: A vibrational generator including an inertial body and a housing means which are relatively movable and where hydraulic fluid is directed into the inertial body through a controlling valve of the inertial body and directed alternately into one or other working chamber which causes the movement of the housing means and any attached load. There is also disclosed a wave form shape detectable from the pressure or flow rate of the hydraulic fluid so that the relative frequency of the drive as compared to resonance can be determined and used for control to maintain resonance. The apparatus has particular application in the frequency range of 20 Hertz to 1000 Hertz.

Abstract: In an underbalanced drilling system and method, a change is induced in flowing bottom hole pressure in a wellbore. Data of the surface flow rate of effluent is then measured in response to the induced change. This measured data is obtained using a multi-phase flow meter before a separator of the underbalanced drilling system. Algorithms in computer software analyze the flowing bottomhole pressure and the measured surface flow rate data and determine both permeability and formation pressure for a portion of the wellbore in realtime during the underbalanced drilling operation. Ultimately, portion of the wellbore is characterized with the determined permeability and formation pressure.

Abstract: Dans un générateur de vibrations comprenant un corps d'inertie et un logement mobiles l'un par rapport à l'autre, un fluide hydraulique est dirigé dans le corps d'inertie à travers une soupape de régulation du corps d'inertie et est dirigé de façon alternée dans l'une ou l'autre des chambres de travail qui provoquent le mouvement du logement et de toute charge associée. La présente invention décrit également une configuration en forme d'ondes détectables à partir de la pression ou du débit du fluide hydraulique, de sorte que la fréquence relative de l'entraînement par rapport à la résonance peut être déterminée et utilisée pour une opération de régulation destinée à maintenir la résonance. L'appareil s'applique en particulier dans la gamme de fréquences comprise entre 20 et 1000 Hertz.

Abstract: A standard rectangular shaped low level toilet cistern is designed to have an outside corner recess - which space contains a height adjustable urinal, in modular unit with it. The urinal is totally enclosed within the volume area of the cistern. The urinal bowl is accessed by a handle / finger pull situated at the top corner side of the cistern - allowing the urinal bowl to be moved quickly outward and upward to an optimum position. The urinal bowl will remain at any chosen height - without external support. When the bowl is placed back in the "closed" position - a push down button [which opens a water valve] - may be activated to release a spray of water into the bowl. This water valve is sited directly over the urinal bowl and could also be a non-concussive type releasing a predetermined quantity of water to rinse out the bowl.

Abstract: A guided optical wave chemical sensor system (10) is adapted to measure the concentration of a chemical species in the presence of thin film surface contaminants on the waveguide (17). The system (10) has a light source (11) which launches two different optical waves into the waveguide (17) to establish evanescent fields (24, 25) of different penetration depths. The detector (15), which includes a data store and an arithmetic unit, is pre-calibrated using a known concentration of the chemical species and the same two different optical waves but prior to the waveguide (17) having been exposed to surface contaminants. When surface contamination is present the detector (15) evaluates the thickness of the contaminant layer from the pre-calibration data and hence evaluates the (unknown) concentration of the chemical species according to a predetermined algorithm.
