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 electro-mechanically 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.

A device for the realization of the method comprises a chamber for the balancing compound, said chamber containing electrodes connected to a pulse generator which is connected electrically with the output of a control unit whose input is connected to a transmitter which registers vibration parameters of the rotor while the latter rotates in supports in front of a nozzle in the chamber.

Abstract: A small-mouthed container having a continuous resinous coating covering the interior of said container and end, said interior coating having a thickness less than about one mil and being free of low molecular weight organic matter, is disclosed herein. Typical containers are food and beverage containers having cylindrical metal walls and circular disc-shaped ends. The coating is typically a comestible coating having a thickness of less than one mil and having no occluded solvent therein. Thermoset resinous coatings are particularly useful.A coating is applied by flowing a mixture of gas and fine resin particles through a nozzle into the vicinity of a plasma arc flame which at least partially melts the surface of said particles and propels said particles into a rapidly spinning container having one closed end. A predetermined quantity of resin is pulsed through the nozzle to deposit on the interior of the container a uniform coating of resin particles.

Abstract: A method for coating a cylindrical container with a thin, resinous coating by spraying powdered resin is disclosed. The technique involves spraying of finely divided resin particles at a velocity of at least about 200 feet per minute from a spray nozzle external to the container into the interior of a rapidly revolving container, particularly slender, cylindrical containers. The container may be sprayed by directing a pulse of a predetermined quantum of resin into the container to deposit a substantially uniform coating. Alternatively, a continuous flow of resin at a predetermined rate may be sprayed into a container. The resin particles are caused to adhere to the container by preheating the container. The coating is rendered continuous by preheating the container to temperatures above the softening point of the resin. Postheating of the coated container at temperatures in excess of about 300.degree. F matures the coating.
