Abstract: A novel method and apparatus for manufacturing magnet wire in a continuous process by which coatings of a flowable resin material may be applied concentrically to a moving elongated filament in thicknesses of about 16 mils or less.

Coatings of one and two mils also can be applied by the method of the invention. By the method and apparatus of the invention, magnet wire can be manufactured by continuously drawing the wire to size, annealing the wire, if necessary, insulating the wire with one or more coats of flowable resin material, curing the resin material, if necessary, hardening the resin material, and spooling the wire for shipment, without interruption at speeds limited only by the filament pay-off and take-up devices used.

The controller also includes other circuitry to maintain linear signal relationships and to center the oscillations of the respective dispensers on the wire.

Abstract: An automobile body is prepared for painting by suspending it roof uppermost from movable conveyor means and moving it first past spraying means which sprays the body at high energy with a phosphate solution so as to initiate a fine crystalline deposit growth on the exposed body panels. The body is then moved roof uppermost into and along a tank containing a flowing stream of phosphate solution, in which it is immersed to a level about that of the window openings. During this movement, a static head of phosphate solution is created in the body so as to generate a flow of the solution from the interior to the outside of the body by flooding the solution under pressure through the window openings. Crystalline deposit growth over the unimmersed upper portion of the body is sustained by spraying the upper portion with phosphate solution.

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.
