Abstract:
A smelt spout cleaner apparatus includes a cleaning head insertable into a smelt spout and movable in a substantially linear path along the smelt spout for thoroughly cleaning the spout. The cleaning head is mounted on one end of a substantially horizontal beam, the opposite end of which is supported in cantilever fashion to a support base which is selectably movable. The support base includes means for longitudinally translating the beam and causing the cleaning head to move in a linear path along the length of the smelt spout.
Abstract:
Damper apparatus for air ports of a chemical recovery furnace is mounted on a removable windbox faceplate. Damper blades extend from cantilevered arms pivoted at the forward side of the faceplate, with the damper blades being otherwise unsupported, i.e., they are not confined to travel in tracks within the windbox. Rather, a spring or counterweight urges the damper blades against the air port opening whereby the whole mechanism is free for removal as a unit with the faceplate. Cooperatively operable air port cleaning apparatus is also mounted on the faceplate.
Abstract:
Apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum having an adjustable damper mounted inside a wind box associated with the furnace adjacent to the air port supplies and regulates the flow of air from the wind box to the furnace through the air port. A metal cleaning head adapted for rotatable insertion into the air port for cleaning excrescent material from the peripheral edges of the air port without blocking air flow through the port is pivotally mounted in a retracted, at-rest position adjacent to and above the air port so as not to interfere with movement of the adjustable damper. During a cleaning cycle, the damper is moved to a retracted position on the floor of the plenum so as not to interfere with the moving cleaning head. A short stroke, double articulated damper positioning mechanism facilitates movement of the damper blade in limited space.
Abstract:
In a method and apparatus for acquiring and recording an identification pattern from the reflectance of the fundus of an eye, a single light source is operable to produce a substantially columnar source beam of infrared light directed into the fixated eye from a plurality of sequential, angularly divergent positions. The light is focused on the retina and reflected in part out of the eye. Variations in the ocular structure contribute to various reflected intensities. The intensity of the reflected light is detected, measured and recorded for each sequential angularly divergent position forming a unique and repeatable identification pattern, or "signature" for each individual.
Abstract:
A three-wheeled leaning passenger vehicle comprises a frame rigidly mounting a passenger seat; a drive wheel rotatably mounted on the frame preferably in a rearward region thereof; a frame-mounted rotary drive cooperatively coupled with the drive wheel for rotation of the drive wheel relative to the frame; and a frame-mounted coast/steer system including two rotatable and preferably front wheels freely rotatable relative to the frame in a forward region thereof, and a handlebar coupled with the two front wheels for turning the two rotatable wheels in a plane defined by their rotational axes substantially parallel with one another to corner, the vehicle being configured to substantially freely lean left and right in a natural response to a driver thereof in the driver seat steering the vehicle and leaning respectively left and right, and, alternatively or additionally, to have controlled leaning in response to a hydraulically or otherwise provisioned leaning, suspension, and stand-up mechanisms. The rotary drive includes a frame-mounted power plant operatively couple-able with the drive wheel, the rotary drive including an internal combustion engine and an electric motor selectively operatively couple-able with the drive wheel to power the vehicle. The power plant is selectively operable to power the vehicle in three modes of operation including a hybrid mode characterized by operation of the internal combustion engine and the electric motor coordinated substantially to optimize fuel economy, an electric-only mode characterized by operation only of the electric motor, and a sport mode characterized by concurrent operation of the internal combustion engine and the electric motor.
Abstract:
A dynamically configurable clamping device for applying a desired electrical current to a tissue membrane includes an input lead electrically connected to the tissue membrane to provide a sensed signal indicative of voltage across the membrane. An input circuit includes an analog-to-digital converter, and is responsive to the sensed signal and provides a digitized signal indicative of the sensed signal. A digital signal processor executes selected program instructions to operate in a selected one of (i) a voltage clamp mode, (ii) a current clamp mode or (iii) a dynamic clamp mode based upon the state of a mode selection signal indicative of the selected operating mode. The digital signal processor provides a digital current command signal indicative of the current to be applied to the tissue membrane. An output circuit receives the digital current command signal, and generates a current signal indicative thereof. An output lead receives and applies the current signal to the tissue membrane. Digital feedback control is advantageous over the traditional systems by providing programmability, capability for dynamic changes of clamping modes, hardware simplification, and integration of multi-channel clamping systems. The digital signal processor in the feedback loop provides programmability in the control algorithm.

Abstract:
Removable apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum mounted adjacent an air port inside a wind box associated with the furnace supplies combustion air from the wind box to the furnace through the air port, and an adjustable damper mounted inside the plenum regulates the velocity and quantity of air flowing through the plenum. An access port in the plenum allows viewing of the air port opening through the plenum. An actuating mechanism withdraws the damper from the field of view to a retracted position wherein the damper depends from the top of the plenum chamber spaced apart from the air port opening. For airflow damping, the actuating mechanism moves the retracted damper toward the air port opening until the damper is adjacent to the opening; then a positioning mechanism pivots the damper to a predetermined position in the air stream adjacent the opening. The damper positioning mechanism comprises a spring loaded cylinder that holds the damper by spring tension, when retracted, above the flow of air through the plenum chamber. Upon further compression of the cylinder by the actuating mechanism, the reduced length of the compressed cylinder forces the damper downward into the air stream. When the actuating mechanism is reversed, the spring tension of the compressed cylinder pulls the damper upward to the retracted position.
Abstract:
An apparatus and method for identifying individuals through the ocular reflectance pattern from the fundus of the eye. A fixation target is provided for positioning and focusing the eye of an individual along its visual axis, being centered on the fovea of the eye. An infrared source provides a substantially collimated source beam of infrared radiation. A scanner directs the infrared radiation into the fixated eye from a plurality of sequential angularly divergent positions forming a substantially circular locus of points substantially centered on the fovea. The light is reflected in part out of the eye and forms a reflected beam. A detector measures the intensity of the radiation reflected from the eye at each sequential location, the intensities being recorded as an identification pattern. At a later date the eye may be presented again to the apparatus in a different rotational position about its visual axis and another pattern generated. The two patterns will be substantially the same, varying only in the relative start points of the data sequences. One pattern may be rotated with respect to the other pattern to ascertain that the two patterns match, thus verifying the identity of the individual.
