Abstract: The present invention relates to an electromechanical system for automating the turning off of the knobs of a stove. The system can quickly identify the occurrence of a gas leak and turn off the knob corresponding to the burner that is leaking. The system is also connected to a user interface, providing real-time information about the status of the burners and allowing the user to turn off the knobs remotely. The system has an improved service life, does not considerably change the aesthetics of the stove and can be designed to fulfil different torque requirements. The invention also relates to cooktops comprising said system.

Abstract: A method for obtaining a biopolymer hemostatic powder including adding in an reactor (1) a mixture of an organic acid (b), a combination of alcohols (b) (d) and a bioadhesive to obtain a binder solution and a step of incorporating on a base of the lower part of a fluid bed reactor (2) a polysaccharide (a) driven by an air stream injected at controlled temperature and speed; on which fluid and micro particles of the polysaccharide (a) are sprayed from the top of said fluid bed reactor (2) the binding solution and where the polysaccharide (a) is chitosan, the organic acid (b) is acetic acid, the alcohol combination (c) is alcohol and polyalcohol and the bioadhesive is polyvinyl alcohol.

Abstract: A method of determining parameters for a burnishing operation includes: using a rolling burnishing element to burnish at least two segments on a selected surface of a material sample, the segments having a common width and overlapping each other by a preselected overlap value; measuring the resulting hardness of the surface; and selecting a working overlap value for a subsequent burnishing operation on a workpiece, based on the measured hardness.

Abstract: A method of reducing crack propagation in an airfoil includes: providing an airfoil having a root spaced apart from a tip, spaced-apart leading and trailing edges, a suction side extending from the leading edge to the trailing edge, and an opposed pressure side extending from the leading edge and the trailing edge, supporting the airfoil against bending loads; and burnishing the airfoil using a burnishing element, so as to create at least one burnished section of residual compressive stress, the at least one burnished section being located adjacent the leading edge and spaced from the leading edge by an offset distance selected so as to avoid deformation of the leading edge.

Abstract: A method for preparing a surface includes providing an article having an article surface, thereafter first processing the article surface to establish a first residual compressive stress state and a first surface roughness in the article surface, and thereafter second processing the article surface by surface compressive texturing to establish a second residual compressive stress state and a second surface roughness in the article surface. The second surface roughness is quantitatively less than the first surface roughness, and substantially no material is removed from the article surface in the step of second processing.

Abstract: A method of reducing crack propagation includes: providing a metallic component having an exterior surface, and using a burnishing element to apply a varying to the exterior surface within a selected area, within which the component has a varying thickness, so as to create a region of residual compressive stress of surrounded by an interior boundary. The distance from the interior boundary to the exterior surface at any location within the selected area is independent of the thickness of the component at that location, and may be controlled by changing the pressure and/or an amount of overlap between burnished segments.

Abstract: A method of evaluating the condition of a rolling burnishing element includes moving a burnishing element having an unknown condition against a surface in a preselected test pattern; while moving the burnishing element, recording at least one test force profile representative of a force acting on the burnishing element in at least one dimension; and comparing the at least one test force profile to at least one baseline force profile to determine a deviation of the condition of the second burnishing element from a baseline condition.
