Abstract: A pop-up gift card includes a card that is foldable along a fold line between closed and opened positions. The card includes a separable perforated section extending over both sides of the fold line. An erectable pop-up display structure comprising a plurality of intersecting slice-form elements is mounted on the perforated section of the card. When the card is closed, the pop-up display structure is in a flattened state, and when the card is opened, the pop-up display structure is in an erected 3-D state. The pop-up display structure can be removed from the card by separating the perforated section from the rest of the card. A support element can be affixed to the perforated section for maintaining the pop-up display structure in the 3-D state when the pop-up display structure is removed from the card.

Abstract: An article comprising a pop-up card is provided. The article comprises a single sheet of paper including a single crease and separating the sheet of paper into a left panel and a right panel, wherein the sheet is in a closed position when folded along the crease, and wherein the sheet is in the open position when not folded along the crease, a pop-up slice-form element coupled to said sheet, wherein the slice-form includes a first plurality of slice-form elements perpendicular to a second plurality of slice-form elements when in the open position, wherein the slice-form element comprises a first and last slice-form element each with a distal tab, and wherein in the open position the pop-up slice-form element is displayed as a three-dimensional configuration, and in the closed position said pop-up slice-form element folds together into a flat configuration.

Abstract: Steel alloys susceptible to case and core hardening comprise 0.05 to 0.24 wt % carbon; 15 to 28 wt % cobalt and 1.5 to 9.5 wt % in nickel, small percentages of one or more additives: chromium, molybdenum, and vanadium; and the balance iron. Carburized roll form and punch dies and tools made from case hardened steel alloys with a reduced hardness core provide high wear and fatigue resistance as well as improved contact and bending fatigue resistance thereby avoiding premature failure and extending the useful life of such tools.
