Abstract: A system, method and/or reamer driver device is provided having a domed external surface and a domed internal surface being concentric to the domed external surface thereby defining a hollow dome or section thereof. At least one cutting tooth is disposed on the hollow dome or section thereof. The cross-sectional thickness T measured substantially perpendicular to the crest of the at least one tooth is greater than the radial distance t between the external and internal domed surfaces. The hollow dome or section thereof is made using an injection molding process or a 3D printing process.

Abstract: Coated solid bodies comprising a core of an active composition and having a water-soluble or dispersible micro-porous or net-coating. The coating improves the mechanical characteristics of the solid body and allows for good dissolution. The coated solid bodies preferably take the form of detergent tablets.

Abstract: An electrochemical cell which has a negative electrode (1) including an alkali or alkali-earth metal dissolved in liquid ammonia, a positive electrode (2), an electrolyte (3), and a separator (4). The positive electrode (2) is constituted by a solution in ammonia of a chalcogen or of a chalcogenide or of an emulsion or suspension in ammonia of a solid compound suitable for intercalating the metal of the negative electrode (1). Said electrolyte (3) includes a solution of an iodide of an alkali or alkali-earth metal.The invention is used in the field of reversible high-power electric cells operating at low temperatures.
