Abstract: A frangible tear strip for toner cartridges used in electro-photographic copying devices, in which bursting strength is increased without making it more difficult for the user to longitudinally tear the strip to create an opening for passage of toner prior to use. This is accomplished by providing multiple areas of transverse reinforcement of the strip either by increased local area fusing of the material, or the lamination of transversely extending reinforcements at spaced intervals. In a preferred embodiment, the reenforcing material extends the entire axial length of the seal. In a further embodiment, the reinforcing material includes a layer of foam material having a rectangular opening overlapping a corresponding opening in a toner cartridge.

Abstract: An abrasive sheet has an abrasive particle layer formed on a surface of a thin flexible resin film. The abrasive sheet is produced by the steps of preparing a releasable film, forming a thin flexible resin film layer on a release agent applied surface of the releasable film and forming an abrasive particle layer on an upper surface of the resin film layer. Thereafter, the resin film having the abrasive particle layer formed thereon is removed from the releasable film, and the resin film having the abrasive particle layer formed thereon is cut into any suitable size. The abrasive sheet can provide higher polishing power during the polishing operation, but it polishes a surface while tracing or following any orange peel on the surface. Therefore, the abrasive sheet is effective for use as the polishing tool that can replace the fine compound buffing process currently utilized in the automobile repairing industry.

Abstract: Using a combination of relatively coarse filler and latex binder, a very high solids coating (about 85% or higher) can be produced with a relatively low working viscosity. These very high solids coatings can be applied in thick single layers and oven cured without cracking. They maintain more than 80% of their original wet thickness. The resulting coating provides an extremely hard and durable surface, even on relatively soft mineral fiber board ceiling tiles or wall panels.

Abstract: An inexpensive, lightweight, strong and durable casting that has a surface appearance simulating carved stone, and is especially adapted for use as a transition between a brick or stone wall and window and door openings. Further, it provides architectural detail to building constructions, especially as a surround for window and door openings. The casting is produced from a mixture of graded aggregates and a resin binder, combined in predetermined proportions to make a soupy mixture that is cast in a mold. The mold is vibrated to cause migration of air bubbles away from the surface of the molded product, and to cause realignment and orientation of the aggregate materials in a way to enhance the structure and surface density of the product. After the casting has set, it is removed from the mold and cured and the surface is sandblasted to erode away some of the resin binder and portions of the aggregate at the surface to produce an appearance that is an accurate simulation of carved stone.

Abstract: A bitumen-based waterproofing membrane is provided with an improved edge for sealing with a contiguous membrane to provide a membrane system with improved waterproofing characteristics. A bitumen-based reinforced membrane sheet is coated with granular material to protect the membrane sheet from ultraviolet rays. However, a section of the membrane sheet is first covered with a piece of protective tape which prevents any granular material from being deposited on the lateral section of exposed bitumen beneath the tape. The membrane sheets are then cut immediately prior to the tape or at the edge of the granular coating and then rolled up. Accordingly, the lateral section of bitumen which is covered by the protective tape is on the innermost part of the rolled-up membrane sheet. During installation, the tape is removed and the exposed bitumen or selvage section is disposed below an adjacent or contiguous membrane. Heat is then applied for an easy and effective seal between two adjacent membrane sheets.
