Abstract: The heat insulation structure for a component of an exhaust system of a piston engine is arrangeable around the component such that an air space is formed between the component and the heat insulation structure, and includes an outer shell layer a middle shell layer that is arranged inside the outer shell layer, and a first inner shell layer that is arranged inside the middle shell layer. A first air gap is arranged between the outer shell layer and the middle shell layer, a first insulation layer is arranged between the middle shell layer and the first inner shell layer, and the outer shell layer is provided with venting apertures for natural ventilation of the first air gap.

Abstract: A multiple line embossing apparatus that is configured to emboss characters on a document, for example a card, on a line-by-line basis. The embossing apparatus uses guides that guide the card, and a tab belt that indexes the card along a card path. A second tab on the belt is provided to move the card in a reverse direction to start a new line of embossing. The guides and the tab belt move are able to move perpendicular to the card path to move the card to a new line of embossing.

Abstract: A system and method for personalizing cards and other secure identification documents. The card personalization system and method provide improved data integrity, system reliability, and system performance. Improvements to card handling and processing within the modules, improved card transfer between modules, improvements to control of the modules, and other improvements are set forth, all of which contribute, individually and collectively, to achieving these goals.

Abstract: A hard, zinc-free gold alloy for an abutment base used with jawbone mounted dental implants is prepared containing approximately by weight 64 percent gold, 22 percent palladium, 9 percent silver, 4.5 percent platinum, and 0.5 percent iridium.
