Abstract: A method for manufacturing an improved transparent panel assembly for fabricating wall and roofing components. The method includes the extrusion of a top and bottom member made of transparent plastic material. Each extruded member includes a top and bottom sheet with interspersed ribs for structural integrity. Each extruded member is supported in spaced relationship by a plurality of beam structures having longitudinal axes substantially normal with the direction of the internal ribs of the extruded panel members. The structure resulting from the improved method includes top and bottom panel members having internal ribs molded in an integral manner, and an elongated support structure mounted between the panel members in a direction substantially normal with the longitudinal axis of the internal ribs.

Abstract: A vaulted skylight apparatus provides modular skylight panel having a pair of first and second spaced apart, generally parallel, sheets of flexible material with an insulating air space therebetween. The modular panel can be curved by cold forming so that the panels can conform to a network of structural tubing, forming a quarter round vault, a half round vault, a structural barrel vault, or the like. The sheets are supported peripherally by a frame which includes first and second frame members that are affixed respectively to the first and second panels forming a seal therewith. The first and second frame members are movably connected, holding the first and second frame members together during simultaneous cold forming of the first and second sheets into the desired curved vaulted position as aforedescribed.

Abstract: A grid skylight support apparatus includes a plurality of prefabricated grid row frames, each formed of a plurality of connected beam supports which define a plurality of bays. Each respective bay has a skylight curb formed by upper flanges of the beam supports that is receptive of a preassembled skylight unit. The sides of each grid row frame provide a mating edge that can register with the mating edge of an adjacent grid row frame during field assembly. The skylights have peripheral support skirts that register upon each bay and a light-transmitting skylight panel which covers the peripheral support. A plurality of cross gutters on each grid row frame, and positioned between adjacent skylights, extends at an angle toward the mating edge of the grid row frame for carrying rainwater to a main gutter channel which is formed by field-assembly of the mating edges of two adjacent grid row frames.

Abstract: A new and improved smoke and heat vent including a frame assembly pivotally attached to a curb member adapted for placement on the roof of a building or the like. The frame assembly supports a dome-shaped cover and is movable between a closed, dome supporting position and an open, released position in which the dome-shaped cover is allowed to fall or slide downwardly by itself to clear an opening for the escape of heat and smoke under emergency conditions. The initial fall of the dome-shaped cover is retarded to remove any extra load such as snow on the cover and the cover is caught by several bands attached to the curb member so that it will not fall to a floor below.

Abstract: A new and improved dispenser device and method for accurately dispensing selected volumes of fluid and for permitting repetitive dispensing of the fluid by the manipulation of a stroke-setting mechanism that selectively varies the amount of liquid pumped from the container by a pump, wherein the stroke-setting mechanism making the settings for dispensing the different volumes of liquid is manipulated from externally of the dispenser device and without the necessity of disassembly from the container with which it is used.
