Abstract: A connection element for mechanical and electrical connection to a contact element of an electrical storage cell comprises a contact receptacle and a clamping device. The contact receptacle is open in a set-on direction and receives a portion of the contact element. The clamping device extends into the contact receptacle in a press-on position of the clamping device. The clamping device is formed from a shape memory alloy transferable by a phase transformation into the press-on position.

Abstract: A fuse component includes an electrically insulating substrate having a top surface, a thick film fuse element applied to the top surface and a cover layer. The cover layer is made of an electrically insulating material having good caloric conductivity. The cover layer can be directly applied to the thick film fuse element and the adjoining zones of the top surface of the substrate. The cover layer can contain a glass having a specific caloric conductivity of >2 W/mK. The cover layer can have a window disposed above a section of the fuse element, the section of the fuse element located within the window being at least partially covered by a solder containing layer.

Abstract: The invention relates to a method for producing a protective component, for example a fuse component or a fusing resistor, including a fusible element and a heating element, which are attached as stacking components to the surface of a substrate. The fusible element is configured in such a way that a current flow between its connections is interrupted, if the fusible component is heated, at least in one fusible region, for a predetermined time period to above a predetermined temperature. The fusible element and the heating element are arranged on the substrate in such a way, that heat created by the heating element is transported to the fusible element and the current flow through the heating element exceeds a threshold value for a predetermined time period. During production, the heating element is positioned next to the fusible element, at a predetermined distance from it.

Abstract: A fuse component (1) has a fusible conductor (2) which extends in a gas filled cavity (3) within a cylindrical tube (4) between two end surfaces (8). Two end caps (5) of an electrically conductive material are applied to the ends of the tube (4) so that an electrical contact is produced with the fusible conductor (2). At at least one of the two ends of the tube (4), a sealing body of a plastic material, which is predominantly elastically compressible but at the same time capable of creep, is introduced into a gap between the base of the end cap and the end surface (8) of the tube (4) and into a portion of the cavity adjacent to the cap base. The sealing body has been compressed between the end surface (8) and the cap base during the manufacture of the fuse component (1) when positioning the end cap (5). The compressed sealing body (7) attempts to expand again, whereby it expands principally into the cavity (3).

In an embodiment, the method includes: a) providing an integrally bladed rotor; b) providing a vibratory grinding. system; c) arranging the integrally bladed rotor in a grinding container of the vibratory grinding system; d) filling the grinding container of the vibratory grinding system with blasting balls; and e) operating the vibratory grinding system filled with the blasting balls and the integrally bladed rotor to accelerate the blasting balls, wherein the accelerated blasting balls simultaneously strengthen the integrally bladed rotor on the surfaces of all the rotor blades and in the annular space between neighboring rotor blades.

Abstract: A fuse element includes a fusible conductor which extends within a gas filled cavity in a cylindrical tube. The fuse element includes a cylindrical tube comprising, an electrical insulator between two end faces of the tube, two end caps of an electrically conductive material being applied to the two ends of the tube such that an electrical contact is produced with the fusible conductor. At least one respective sealing element is inserted in at least one of the two ends in a space between the cap base and the end face of the tube and/or into a portion of the cavity of the tube adjacent to the end face such that one or more pressure balancing passages remain between the gas filled cavity within the tube and the external surroundings of the fuse element. The one or more pressure balancing passages are of such small cross-section that changes in pressure in the cavity are balanced only very slowly.
