Ronald C White

US Patent:

40045501, Jan 25, 1977

Filed:

Apr 4, 1975

Appl. No.:

5/565149

Inventors:

Ronald D. White - Cypress CA
John F. Gibson - Long Beach CA

International Classification:

B05C 1110
B05C 500

US Classification:

118314

Abstract:

A plurality of glass slides having specimens such as blood smears disposed thereon are prepared for microscopic viewing by an apparatus which automatically applies preparation solutions to the slides such as stains and buffers and thereafter automatically drys the completed slides. The staining and buffering solutions are deposited evenly over the surfaces of the slides carrying the specimens by a timed operation of one or more electromechanically actuated aerosol dispensers which produce fine sprays of the desired preparation solutions. Simultaneously with the generated spray, the plurality of slides are rotated at a relatively slow rate to cause a uniform distribution of the spray particles on the slide surfaces. Following the staining and buffering mode, an automatic drying mode is initiated in which the plurality of slides are rotated at a relatively higher speed for a timed interval after which the apparatus automatically turns off and the completed slides may be removed from the apparatus.
