Abstract:
A combustor dome assembly for a gas turbine engine having a longitudinal centerline axis extending therethrough, including: an annular dome plate having an inner portion, an outer portion, a forward surface and a plurality of circumferentially spaced openings formed therein, wherein a radial section is defined between adjacent openings; an annular outer cowl connected to the outer portion of the dome plate; an annular inner cowl connected to the inner portion of the dome plate; and, a swirler located between the forward surface of the dome plate and the inner and outer cowls in substantial alignment with each of the openings in the dome plate. Each swirler further includes a forward portion and an aft portion and is retained by at least one tab member located upstream thereof so as to be movable in a radial and axial direction.
Abstract:
A device for starting an internal combustion engine comprising a first clutch member attachable to the engine, and a second clutch member attachable to a portable drive means, wherein the first and second clutch members are engageable so that the drive means transmit force through the clutch members so as to turn and start the engine, and wherein, once the engine starts, the first and second clutch members automatically disengage from each other and wherein at least one of the first and second clutch members retracts. Preferably at least one of the first and second clutch members comprises resilient biassing means against retraction. A preferred embodiment relates to a lawnmower comprising such a device.
Abstract:
A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots is controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.
Abstract:
The present invention provides a method and apparatus for generating an animated character representation. This is achieved by using marked-up data including both content data and presentation data. The system then uses this information to generate phoneme and viseme data representing the speech to be presented by the character. By providing the presentation data this ensures that at least some variation in character appearance will automatically occur beyond that of the visemes required to make the character appear to speak. This contributes to the character having a far more lifelike appearance.
Abstract:
A cutting device for the cutting and reduction of matter from a surgical site having a cutting head having an entry tip and a cutting blade positioned on opposed leading edges of a window formed through the interior of the cutting head. The window includes angled walls extending from each cutting blade along the circumference of the window. The cutting head is attached to a shaft for mounting the cutting device to a rotary surgical drill. The cutting head can also have a blade on the outer perimeter of the head. The matter is removed and further reduced as the cutting head is rotated at the surgical site. The geometry of the cutting head and entry tip can be varied for particular surgical procedures. The cutting device can also include a cannula or drill guard.
Abstract:
In a filtration apparatus in which a flocculant is added to promote flocculation, efficient use of the flocculant is ensured by measuring an operational parameter of the apparatus dependent on the degree of flocculation, and adjusting the amount of flocculant being added to the minimum that causes maximum flocculation. As the operational parameter, measurement can be made of the depth of a pool of the material at the lower end of an upwardly inclined filter belt, or of the resistance to movement of a part of the apparatus e.g. the torque required to rotate a filter drum.
Abstract:
A shelving system (10) comprising a plurality of tubular posts (12) and a plurality of rail segments (72) securable parallel to the posts (14). Each of the rail segments (72) comprises an elongate member having a U-shaped cross section such that the rail segment includes a central wall (74) and first and second side walls (76, 77) such that the posts (12) are received between the first and second side walls (76, 77) and wherein the rail segments (72) include apertures (46) along the lengths thereof to receive tracks (48) for supporting drawers (51).
