Abstract: A modular drawer system provides a system of interchangeable components that are easy to assemble. The system requires few fasteners because most of the parts are slidably interconnected. Many parts perform dual functions. A removable lock tray and a tracking mechanism to provide easier steering of a rolling cart are provided. A lock bar assembly with few moving parts is easily assembled. In addition, an accessory track provides two types of attachments for accessories, a more flexible, snap-on attachment and a more permanent, bolted attachment.

Abstract: A method of applying tiles to a roof, the tiles being of at least two different appearances, includes establishing a collection of pattern units, each pattern unit representing an arrangement of a plurality of tiles formed into a specific pattern, the specific pattern of each pattern unit being different from the specific pattern of every other pattern unit in the collection of pattern units. Each pattern unit includes representations of tiles of at least two different appearances, such as different colors. Tiles are applied according to a first one of the pattern units, to a first portion of the roof. Tiles are applied according to one of the pattern units, to a second portion of the roof that abuts the first portion of the roof. Additional tiles are applied to additional portions of the roof, the tiles being applied to each additional portion of the roof according to one of the pattern units, with each additional portion of the roof abutting a previously applied portion of the roof.

Abstract: In a method of forming a pattern of granules on a moving asphalt coated sheet, a blend drop of first and second granules is discharged onto the sheet. The blend drop forms a granule deposit on the sheet including an inner portion of first granules and an outer portion of second granules. An apparatus for use in the method includes a nozzle having an orifice for discharging a blend drop of first and second granules onto the sheet. A first granule feed chamber is provided for feeding first granules into the nozzle. A second granule feed chamber is provided for feeding second granules into the nozzle. The first and second granule feed chambers are positioned so that the first granules are fed inside the second granules in the nozzle.

Abstract: In a method of forming a pattern of granules on an asphalt coated sheet moving in a machine direction, a flow of separate first granules and second granules is discharged onto the sheet. The flow of granules is rotated to form a pattern of first and second granules on the sheet that changes along the machine direction. Another embodiment of the invention provides a method of forming a pattern of granules, in which the flow of granules is oscillated in a direction transverse to the machine direction. The flow of granules can also be discharged intermittently onto the sheet.

Abstract: In a method of forming an irregular pattern of granules on an asphalt coated sheet, a flow of granules is discharged toward the sheet. The granules are deflected onto the sheet with a deflector having an irregular surface to form a granule deposit having an irregular pattern. In one embodiment of the method, the deflected granules are controlled with a shield. Apparatus for forming an irregular pattern of granules on an asphalt coated sheet includes a granule applicator for discharging a flow of granules, a deflector having an irregular surface for deflecting the granules, and optionally a shield for controlling the granules.
