Abstract: Apparatus for applying a synthetic resin coating of predetermined thickness to various articles of different sizes and shapes from a relatively rapidly deteriorating solution of the resin in which an intermittently driven conveyor housed in a controlled atmosphere and suspending different article groups of like articles at spaced locations along the conveyor successively moves the articles from a loading station first to a cleaning station at which the articles are subjected to the action of an ultrasonic cleaner, then to a destaticizing station, then to a coating station at which a dip tank is rapidly raised to immerse the articles in the solution and is lowered at a controlled rate to provide a coating of the required thickness in a single operation, and finally through a precuring zone in which the coating dries tack-free to the loading station at which the coated precured articles can be removed.

Abstract: A flip-up visor assembly for a protective sport helmet or the like, in which a band secured at spaced points along the length and intermediate the ends thereof across the brow portion of a helmet with resilient pads disposed between the free band ends and the outer surface of the helmet to accommodate a range of helmet sizes carries adjacent its ends a pair of pivot pins which pivotally support the visor lens frame for movement between a position at which the visor lens is in front of the upper portion of the wearer's face and a position over the helmet at which the lens is clear of the wearer's face. Associated with the pivot pins are interengageable positive stop means for limiting the movement of the frame between its two extreme limit positions and spring loaded detent means for releasable retaining the visor in its limit positions and in spaced positions intermediate its limit positions.
