Title: Self cleaning imaging material level dispensing system
Inventor: STRUCZEWSKI TIMOTHY G
IPC: G03G15/08
Filed: 1997-11-27
Granted: 2001-01-09
Abstract: A reproduction apparatus imaging material dispensing system has a replaceable and rotatable imaging material dispensing container from which an at least partially magnetically attractable consumable imaging material is dispensed. There is an optical imaging material level sensing system mounted outside of the container for optically detecting the imaging material inside the container through translucent walls thereof and signaling an insufficient remaining quantity of imaging material.  A magnetic brush cleaning system internally cleans imaging material from the inside of a annular translucent wall area of the container to provide and maintain relatively unobstructed such optical sensing.  It can be provided by a stationary magnet mounted outside of but adjacent to the container to attract magnetically attractable imaging material to the inside of the container wall to form a magnetic cleaning brush to clean the translucent wall annular area.  This allows a light receiving sensor on one side of the container to detecting light from a light emitter on the other side of the container through the magnetically cleaned translucent annular band.  The magnet can extend substantially the full length of the outside of the container to clean the entire interior thereof.

Abstract: A non-contaminating flow meter having an isolation member. The flow meter includes two pressure sensor transducers (42, 44), located on opposite sides of a restriction (35) in a conduit. Each of the pressure transducers is isolated by an isolation member (38) from exposure to fluids flowing through the conduit. The flow meter may be placed in line within a fluid flow line carrying corrosive materials. The square root of the difference in pressure between the two pressure sensors is calculated to determine the rate of low within the fluid line. The flow meter compensates for changes in temperature within the fluid flow line and activates an alarm if the pressure of flow rate within the fluid flow line exceeds or falls below a threshold level.

Abstract: A coupling for connecting a distal end of a corrugated tube (14) with a fitting (16) having a forward coupling end. The coupling end includes a collet (40) receivable coaxially over the distal end of the tube and including a circumferential wall portion (42) which extends axially from a forward first end (46) to a rearward second end (48). The second end is configurated as having an outer portion and an inner portion of a diameter smaller than the outer periphery of the tube. The inner portion is configured to be receivable within the root portions of the tube for retaining the collet thereon, and presents a generally rearwardly-facing compression surface. The wall portion is longitudinally dissected through the second end thereof into at least a pair of arcuate, cantilevered segments. Each segment is resiliently yieldable for radial outward movement allowing the tube crest portions to be received through the second end of the wall portion as the collet is advanced forwardly over the distal end of the tube into retention within one of the root portions. A fastening member (80) is journaled over the collet's first end and is engageable with the coupling end of the fitting to draw the collet and the distal end of the tube toward the fitting. The fastening member has an inner radial surface extending to a rearwardly-facing shoulder portion (100) configured to abuttingly engage the outer portion of the collet's second end for urging the collet rearwardly toward the fitting.

Abstract: Improvements are provided for a dental air abrasive system of the type which utilizes a compressed gas or air which creates a gas stream. Abrasive particles are introduced into the gas stream and expelled out through one end of a nozzle whereupon the abrasive laden gas stream impinges upon the target, i.e. tooth amalgam, composites, stain and/or tooth dental filling materials. The improvements include the use or two or more hoppers each containing different sized abrasive particles, which are selectively fed either together or independently of each other, into the gas stream. Different sized abrasive particles are provided in each hopper for cutting different types of tooth structures. Other improvements include the use of fluorescent and/or colored abrasive particles to facilitate the aiming process, a laser beam, strobe, white light or other illuminating means for aiming the abrasive stream and/or illuminating the target area as well as a disposable nozzle for hygienic reasons. Other improvements include the use of a vacuum evacuation system to minimize dusting of the abrasive particles, as well as a dam removably positioned within the patient's mouth which reflects the abrasive particles back towards the evacuation system. Still other improvements include the use of a microvalve adjacent the nozzle which, when closed, terminates gas flow through the fluid passageway in order to further minimize dusting of the abrasive particles.

Abstract: A flicker photometer has beam generating means (1, 8 and 4) for generating two beams of light of different colours. Light from the beams is viewed at the viewing means, and the intensity of light of one beam relative to that of the other beam can be adjusted by adjustment means comprising an attenuating filter (20) which is movably mounted in the path of one beam. Movement of the filter relative to the beam alters the degree to which the beam is attenuated, and is achieved using an electric motor (22). The motor provides a relatively easy means of adjusting the filter position, and can be used to provide coarse and fine adjustments in response to suitable signals from an optical encoder. The motor also enables the filter, along with the beam generating means, to be mounted on a movable table for use in enabling the photometer to accommodate both short and long-sighted subjects.
