    Abstract: Plywood is made by continuously propelling a liquid plywood glue in unfoamed condition at a predetermined flow rate, continuously foaming the glue as it is propelled, and continuously extruding or otherwise applying the foamed glue to the surface of a plurality of wood veneers. The flow rate of the unfoamed and foamed glue is maintained substantially the same on a unit weight of liquid glue per unit time basis. The veneers then are laid up into a plywood assembly and pressed into a plywood panel. The veneers may be preheated to expedite setting of the glue. The method is applicable generally to the application of a foamed liquid to a solid surface.

    Abstract translation: 胶合板通过以预定流速连续地推动未发泡状态的液态胶合板胶，通过在推进胶水的同时不断地发泡，并将发泡胶连续地挤出或以其他方式施加到多个木胶合板的表面上而制成。 未发泡和发泡胶的流速在每单位时间的液体胶的单位重量上保持基本相同。 然后将单板铺设成胶合板组件并压成胶合板。 胶合板可以被预热以加速粘合剂的设置。 该方法通常适用于将泡沫液体施用于固体表面。

    Abstract: Disclosed is a process for coating a substrate with a transparent, weather-resistant, light-stable exterior varnish or lacquer comprising blending a transparent coating resin free of drying types of unsaturation, and free of chlorine and bromine, and a minor amount of a compatible transparent, uncured, unoxidized, water-insoluble linear condensation resin of formaldehyde and a phenol having the formula:

    wherein R'' is a radical selected from the group consisting of alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, aryl, and substituted aryl, and R and R'''' are radicals taken from said group or H, the methylene groups in the condensation resin being in the ortho, ortho'' position with respect to the hydroxy group, applying a thin coating of the transparent composition to a substrate, and exposing said coating to conditions, for instance outdoor exposure and/or an oxidation catalyst such as the metallic driers commonly used with unsaturated drying oils, such that oxidation of the phenolaldehyde condensate is achieved to an extent that at least some of the ortho, ortho'' -CH2- groups connected to phenol rings are converted to

    groups, whereby the oxidized phenol-aldehyde condensate protects the coating resin and substrate from oxidation or degradation induced by actinic light or other means, the amount of condensation resin being from 5 percent to 35 percent, preferably 10 to 30 percent, based on the combined weights of the resins. The phenol-aldehyde resin may be oxidized prior to being introduced into a coating resin, or it may be oxidized while mixed with the coating resin when it is in liquid form, as an aqueous dispersion, organic solvent solution, or non-aqueous dispersion of the polymer.
