Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
An apparatus for treating dental objects with radiation of a selected spectral range, comprising (a) a housing, (b) support means including a horizontal glass plate for holding an object and being transparent for radiation of said selected spectral range, (c) a first lamp for emitting radiation containing said selected spectral range, (d) a first reflector for reflecting radiation of said selected spectral range, said first lamp and reflector being disposed so as to direct radiation in a substantially transverse direction, (e) a mirror disposed above said support means to redirect the radiation from said first lamp and reflector to said support means, said mirror being removable to allow access to said support means, (f) a second lamp disposed below said support means and emitting radiation containing said selected spectral range, and (g) a second reflector disposed below said support means and reflecting radiation of said selected spectral range substantially upwardly through said glass plate.
Claim 2
Independent Claim
154 words
An apparatus for treating dental objects with radiation of a selected spectral range, comprising (a) a housing, (b) support means including a horizontal glass plate for holding an object and being transparent for radiation of said selected spectral range, (c) a first lamp for emitting radiation containing said selected spectral range, (d) a first reflector for reflecting radiation of said selected spectral range, said first lamp and reflector being disposed so as to direct radiation in a substantially transverse direction, (e) a mirror disposed above said support means to redirect the radiation from said first lamp and reflector to said support means, said mirror being removable to allow access to said support means, (f) a second lamp disposed below said support means and emitting radiation containing said selected spectral range, and (g) a second reflector disposed below said support means and reflecting radiation of said selected spectral range substantially upwardly through said glass plate.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1, wherein said selected spectral range is between about 400 nm and about 500 nm, at least one of said first and second reflectors being transparent for radiation above said selected spectral range.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1, wherein said first and second reflectors are substantially paraboloid-shaped.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1, wherein said first and second reflectors are disposed so as to surround said first and second lamps, respectively, and are transparent for radiation above said selected spectral range.
Claim 6
Dependent Claim
56 words
The apparatus of claim 1, wherein said support means is enclosed in a vacuum tight chamber, said chamber including means for connection to a vacuum source, first and second transparent windows opposing said first and second lamps and reflectors, respectively, a lid carrying said mirror, and means for sealing said lid when in its closed position.
Claim 7
Dependent Claim
44 words
The apparatus of claim 5, comprising first and second filter means for transmitting radiation of said selected spectral range and adsorbing radiation above said selected spectral range, said filter means being disposed between said windows and said first and second lamps and reflectors, respectively.
Claim 8
Dependent Claim
18 words
The apparatus of claim 6, comprising means for drawing cooling air along said first and second filter means.
Claim 9
Dependent Claim
28 words
The apparatus of claim 1, comprising a control circuit for switching off said lamps upon expiry of a predetermined time interval after the lamps have been switched on.
Claim 10
Dependent Claim
49 words
The apparatus of claim 8, comprising a counter and a visual count display, said control circuit including means for indexing said counter during said time interval, and means for stopping said counter and intermittently actuating said display upon interruption of current supplied to at least one of said lamps.
Claim 11
Dependent Claim
22 words
The apparatus of claim 5, comprising a visual display and means for intermittently actuating said display upon malfunction of said vacuum source.
