Abstract: An overpressure relief plug including a rupture disc and engaging a fill valve in series downstream fluid communication with respect thereto. A gas spring may include a fill port, and the overpressure relief plug and the fill valve in the fill port.

Abstract: A gas spring includes a fill valve, and a rupture disc carried by the fill valve. An overpressure relief and fill valve assembly includes a valve housing with a valve passage, the fill valve carried by the valve housing and including a valve stem extending into the valve passage and an overpressure relief passage extending through the fill valve, and a rupture disc carried by the fill valve in communication with the overpressure relief passage. A gas spring may include the valve assembly therein.

Abstract: A device that aids in the holding of a book or binder is fully adjustable to the hand size of the holder by parting and remating of hook and loop fastening strips attached to U-shaped clips, the U-shaped clips being placed at the top and bottom of the outside surface of the backbone or spine of a book or binder.

Abstract: A label for marking an article for identification and description includes a sheet of material such as paper or vinyl having one surface coated with an adhesive material, and at least one closed peripheral cut formed through the sheet defining the external boundary of identification and descriptive indicia. A method for marking an article for identification and description includes making at least one closed peripheral cut through a sheet of material in selected portions of the sheet to define the external boundary of identification and descriptive indicia, adhesively attaching the closed peripheral cut out portions of the sheet to a surface of the article, and covering the closed peripheral cut out portions and an area of the article surface beyond the external boundary of the closed peripheral cut out portions with a covering material thereby producing a three-dimensional image of the closed peripheral cut out portions.

Abstract: A label for marking an article for identification and description including a sheet of material such as paper or vinyl. In one embodiment, selected closed peripheral portions of the sheet material are removed from selected areas of the sheet defining identification and descriptive indicia. One surface of the sheet is coated with an adhesive material for attaching the label to a substrate. In another embodiment, at least one closed peripheral cut is made through the sheet defining the external boundry of identification and descriptive indicia.
