The invention relates to a hand-guided device (10) for setting a setting element (12) in a component. The device comprises a handle (14) for holding the device, a carriage (34), which can be moved in relation to the handle and which bears a rotatably supported drive shaft (46), at one end of which a holder for the setting element is formed, a force accumulator (44), which is arranged between the handle and the carriage and which serves to store a defined advancing force, with which the force limiter can be loaded by means of a relative motion between the handle and the carriage, and a force limiter (64) for limiting the advancing force stored in the force accumulator. The force accumulator is designed to apply the stored advancing force to the setting element by means of the carriage. The invention further relates to a method for manually setting a setting element by means of said device.

The invention relates to a method for securing an attachment (3, 33) to a component, in particular a rotor blade (1), in which the component is provided with an adhesion surface (36), the attachment (3, 33) is provided with a corresponding adhesion surface (9), the attachment (3, 33) is provided with an adhesive-conveying connection to the corresponding adhesion surface (9), the adhesion surface (36) is placed on the corresponding adhesion surface (9), a gap (53) is formed between the adhesion surface (36) and the corresponding adhesion surface (9), the attachment (3, 33) is pressed against the corresponding adhesion surface (9) and at the same time the adhesive (80) is injected into the gap (53) through the adhesive-conveying connection.

An apparatus for processing a workpiece with ultrasound comprises a base frame having a slide. A tool holder is connected to the slide via leaf springs, whereby a lifting device can move the tool holder relative to the slide.

A sealing jaw assembly for a sealing unit, and in particular an arrangement for suspending a sealing jaw in a socket is disclosed. The arrangement is based on a first and a second spring arrangement wherein the action of the first spring arrangement onto the sealing jaw may be activated and deactivated.

Apparatus (10) and associated method for joining thermoplastic composite components (66, 68) to one another. Firstly, an electrically-conductive carbon-fibre textile (74) is positioned between two pieces of thermoplastic composite (66, 68) to form a weldable assembly (64), and pressure is applied to the weldable assembly (64). A voltage is then applied across the carbon-fibre textile (74) to heat the carbon-fibre textile (74), thereby melting the thermoplastic (82) of a carbon-fibre textile facing surface (78, 80) of each thermoplastic composite (66, 68), wherein the melted thermoplastic (82) fluidly fills the inter-fibre space (84) of the carbon-fibre textile (74). Upon removing the voltage to allow the carbon-fibre textile (74) to cool, a weld (86) forms between the two thermoplastic composites (66, 68) as the thermoplastic sets.
