Abstract: A drive for drawing an absorbent web of dry wipes from a supply and an application applying moisture to a selected width of the webs.

Abstract: An intersection spacer is disclosed for use in a subceiling structure of a grid of open-ended runner beams and intersecting open-ended cross beams, the intersection spacer being generally square in horizontal cross section with inverted vertical corner edges forming four outwardly directed protrusions adapted to engage within the beam ends. A top plate on the spacer bears the weight of the ceiling. A bottom cap on the spacer carries a decorative panel. The spacer may be made of two identical mating halves. A method of assembling a subceiling with such intersection spacers is also disclosed.

Abstract: A suspended grid subceiling and panel units therefor having the appearance of a continuous expanse of decorative light-transmitting block masonry. In a preferred embodiment, the panels units are assemblies of an opaque subgrid of rails and cross rails and translucent subpanels simulating the mortar lines and faces of glass block. The undersides of the grid main runners and cross runners are similar in shape to the subgrid rails and cross rails and have a surface finish matching the color and texture of the subgrid undersides.

Abstract: In a sub-ceiling system having removable modular panels of intersecting thick louvers defining a grid pattern with open cells, supported in a framework of suspended rails of inverted T cross-section, the panels are surrounded by perimeter strips attached to the ends of the louvers. The perimeter strips integrate visually with the exposed lower flange portion of the support rails to simulate louvers so as to conceal the panel boundaries and present the overall appearance of a monolithic grid pattern over the entire finished ceiling area while providing the utility and convenience of damage-resistant modular panels which are extremely easy to install and remove.
