Abstract: Method and apparatus for providing a completely encircling coating of an organic polymeric material on a localized region of a glass container. At a coating station, a glass container is rotated through at least 360 degrees. During the rotation, a material application head furnishes fluid organic polymeric material to the surface of the localized region of the glass container which is to be coated. Stop members hold the application head a fixed distance from the localized region and determine the perimeters of the encircling coating and a doctoring edge of the application head helps form a uniform layer or coating of the organic polymeric material completely encircling the localized region.

Abstract: In fabricating sealed contacts, often their axially extending leads are solder coated to protect them from contamination and to enhance their solderability into circuits. An apparatus for solder coating the leads, which minimizes their bending, includes a conveying apparatus that moves the contacts through various stages of the solder coating apparatus to form layers of solder on the leads. These layers, which are carefully controlled, are no greater than a certain maximum thickness, and are thinner on the ends of the leads than on the side surfaces thereof.To coat the leads, the contacts are individually mounted in a plurality of holders, each of which is fixed to an individual bead of an endless bead chain of the conveying apparatus.

Abstract: Apparatus and method automatically for moving elongated objects into and out of a hot dip galvanizing kettle or the like includes a screw feed conveyor system that continually maintains control over the elongated objects while feeding and removing the objects at a uniform predetermined rate. The screw feed conveyor system includes at least two generally U-shape screws which are rotated about their axes to feed elongated objects horizontally placed thereon at opposed diametrical sides thereof through the galvanizing kettle, said screws, if desired, having flights with selectively varying pitches to tilt the objects for entry into the kettle and drag out from the kettle.

Abstract: A machine is presented which includes a liquid-coating or battering unit associated with a dry-coating or breading unit, the units being useful separately or when combined as described. The battering unit includes a batter reservoir in which an open mesh wire belt under tension travels beneath a submerger wheel so as to gently nip the product and drag it below the surface of the batter. In the breading application unit, the loose breading material is stored in a hopper above which is a flat slider plate over which passes an open mesh wire conveyor belt in its product-advancing run. This belt then passes downwardly after discharging the coated product, to a lower point in the hopper where the belt is inclined upwardly toward the opposite end of the unit at the inlet end of the slider plate. This portion of the conveyor belt is the breading material elevating run and it travels close to an inclined bottom wall of the hopper.
