  • Patent number: 11426788
    Abstract: A joining method for connecting a first component to a second component without pre-punching. The first component and the second component are positioned relative to one another prior to the connection by an auxiliary joining element, which is joined via a joining device to the components positioned relative to one another. The auxiliary joining element firstly passes through the first component without pre-punching and is then connected to the second component without pre-punching. Before the components are connected by the auxiliary joining element, the first component is thermally pre-treated at the joining area via an electric arc formed between the first component and an electrode of the joining device. A heat-affected zone is formed on the first component in the joining area, and the first component in is weakened or melted in the heat-affected zone.

M2+ represents a bivalent ion of a metal chosen from calcium, magnesium, strontium, copper, zinc, cobalt, manganese and nickel, or any mixture of such bivalent ions. R+ represents a monovalent ion of a metal selected from potassium, lithium, sodium, and silver, or any mixture of such monovalent ions. This material in particular can be used in manufacturing of bone replacements or prosthesis coatings.

  • Patent number: 8216630
    Abstract: The present invention relates to a porous biomaterials surface activation method by coating with a layer of apatitic nanocrystals in order to increase their surface reactivity. The method according to the invention is characterized by the following steps: a) preparing a nanocrystalline apatitic calcium phosphate analogous to bone mineral by mixing a calcium salt solution with a phosphate salt solution in a Ca/P ratio ranging between 1.3 and 2 at a temperature ranging between 0 and 60 ° C., b) slurrying the mixture obtained in step a) in an aqueous solution so as to obtain a fluid, homogeneous paste containing 80 to 98% of water, c) bringing a porous biomaterial into contact with the suspension obtained in step b), d) drying the porous biomaterial at a temperature below 100 ° C.

  • Patent number: 7645969
    Abstract: A method, device, and projectile having a device for guiding or piloting projectiles or missiles (self-propelled or non-self-propelled), to deflect, in a direction Y, a hypervelocity projectile operating in a gas, such as a shell, a bullet, or a missile, having a nose, generally in the shape of a cone, with a more or less pointed tip, by generating a first high-voltage discharge able to produce a plasma over a first limited sector of the projectile surface and in direction Y, maintaining the plasma, and generating another low-voltage discharge able to supply the plasma with energy over a second limited sector of the projectile surface and in direction Y, the first and the second sectors being different and may overlap.

  • Patent number: 7517539
    Abstract: The present invention provides a novel process for producing a calcium phosphate cement or filler which hardens in a temperature dependent fashion in association with an endothermic reaction. In the reaction a limited amount of water is mixed with dry calcium phosphate precursors to produce a hydrated precursor paste. Hardening of the paste occurs rapidly at body temperature and is accompanied by the conversion of one or more of the reactants to poorly crystalline apatitic calcium phosphate. The hardened cements, fillers, growth matrices, orthopedic and delivery devices of the invention are rapidly resorbable and stimulate hard tissue growth and healing. A composite material is provided including a strongly bioresorbable, poorly crystalline apatitic calcium phosphate composite and a supplementary material. The supplementary material is in intimate contact with the hydroxyapatite material in an amount effective to impart a selected characteristic to the composite.
