Abstract:
Un assemblage de brûleurs assure un prémélange à 100% de combustible et d'air en aspirant l'air dans au moins un courant de combustible à haute vitesse sans régulation indirecte. D'une manière spécifique, l'assemblage à tuyère d'injection du combustible dans un col (8) comprend une pluralité de buses (2) disposées en cercle. De préférence, le mélange air/combustible reçoit un mouvement de tourbillonnement grâce au positionnement angulaire des buses. Le diffuseur comprend un diffuseur conique primaire (10) suivi d'un diffuseur en pointe (12).
Abstract:
Diesel fuel is vaporized and then burned on a cylindrical screen flame holder (110). The fuel is vaporized in a finned, vertical tube vapor generator (40) and directed through a superheater tube (60) past the flame to a flow control valve (300) and nozzle (320). A flow restriction (34) is provided between a liquid fuel supply and the vapor generator. The flame holder is vertically supported over a mixer (340) and the nozzle. A flame deflector (120) about the flame holder and a reservoir (366) about the nozzle collect fuel condensate during start-up.
Abstract:
A multi-axis force platform for determining forces and moments exerted on the platform along x, y and z axes includes at least one multi-axis spring. The multi-axis spring includes a block of rigid material through which a pattern of slots pass through to form a series of deflectable beams separated from each other by the slots. The deflectable beams surround an interior region of the spring and elastically couple the interior region of the spring to an outer region of the spring such that the interior region can deflect relative to the outer region along x, y and z axes when subjected to a load. One or more magnetic sensors are positioned within the interior region of the spring for sensing loads exerted on the spring.
Abstract:
A device for measuring displacement and force comprises two masses of material linked together by a parallel beam linkage which permits displacement of one mass relative to the other in a single direction. The displacement or force input to be measured is applied to one of the masses in the allowable direction. The displacement of the masses with respect to each other is sensed by a sensor. In a preferred embodiment, the sensor comprises a Hall effect sensor attached to one of the masses positioned between two magnets attached to the other mass. Movement of one mass relative to the other changes the magnetic field around the Hall effect sensor. The change is sensed by the Hall effect sensor.
Abstract:
An apparatus and method for a multi-axis wheel transducer are disclosed. The apparatus of the invention comprises a wheel transducer for measuring the loads and moments acting on a vehicle wheel. Tubular load cells positioned in a radial fashion around the perimeter of the transducer hub join the rim and hub. Loads and moments acting on the rim of the wheel are transferred through the spoke-like load cells to the hub of the wheel. Sensors strategically positioned around the circumference of the tubular load cell monitor the intensity of the loads and moments. To detect angular position of the wheel, a light source generates a cone of polarized light to flood the wheel of the vehicle and detector-polarizing filter pairs detect an angle of the polarization relative to the wheel to determine its angular position. The transducer hub computer processes the sensor data and transfers the information via infrared signal to a computer located in the fender of the vehicle.
Abstract:
In a force measuring platform, a top plate (12) is supported on tubular load cells (16). The load cells have strain gages to measure the strain due to the horizontal shear forces. The "shear" strain gages also measure moments about the Z axis when properly placed in a bridge circuit. Strain gages mounted to measure vertical strain indicate vertical forces and moments about horizontal axes.
