A molding method and a molding device are provided for removing distortion in a separator. In the molding method and the molding device, first and second dies which correspond to a product shape of first and second pre-molded surfaces of a separator base material. In a first molding step, the first die is pressed by applying an impact force towards the first molding surface side of the separator base material causing the separator base material to move towards the second dies. In the second molding step, the second dies are pressed towards the second molding surface side of the separator base material, and the molding part of the separator base material is sandwiched between the first die and the second dies.

An impact device for an elevator installation includes an impact part and a free-fall mass. The impact part is arranged on a rail of the elevator installation such that the impact part is supported on a sliding bracket attached to the rail. The free-fall mass is guided so as to move relative to the impact part. The guiding of the free-fall mass is configured such that the free-fall mass, initially raised to a determined free-fall height, transmits to the sliding bracket, at the end of its free-fall path and via the impact part supported on the sliding bracket, an impulse which is dependent on the determined free-fall height. Further, the impact device can be used in a method for post-adjusting rail securing devices for an elevator installation.

A punch tool includes a body having a contoured profile configured for holding in a user's hand. The body includes at least one opening for receiving a user's digits and the contoured profile has at least one extension configured for contact with another of the user's digits. A strike portion for applying an external force is located at an upper portion of the body centered on a force line extending through the body. An impact portion is located at a lower portion of the body concentric with the force line and has an end tip configured to focus at least a portion of the external force to a work surface.

Repair device for a dent is provided in metal bend tube part of musical instrument capable of effectively performing repair work in short time, not by conventional repair method using dent ball. In the device, a pressurizing device main body is also provided formed by connecting base member having an L shape in side view with first fulcrum at a base thereof and movable pressurizing member whose upper surface has convex arc-shaped surface in side view and has a second fulcrum at center part of lower surface, through a first and second arm. A wire, passes through the second arm and upright part of base member in axial direction, is provided, stopper is fastened to an end of wire which has passed through to outside of second arm, and wire passes through inside of curved metal tube and other end side of wire is connected to a foot pressing device.

A method for repairing a dent situated on a wall includes hammering the dent using at least one ferromagnetic striker, positioned in line with the dent to be repaired, and at least one electromagnetic emitter that generates at least one electromagnetic field configured to animate the ferromagnetic striker according to alternating movements such that it hammers the wall. A repair device makes it possible to implement the method.

A tool for removing dents includes a first upper handle extending transversely and connected to a first downwardly extending rigid bar portion and a second lower handle extending transversely and connected to a second upwardly extending rigid bar portion, both portions interconnect a first lateral rigid bar portion disposed in a first X-Y plane between the first upper handle and the second lower handle. The handles are both on a first side of a second Y-Z plane and the handles extend generally in an opposing Z direction from one another. A second rigid upper bar portion extends generally in a Z direction opposing forming a U shape between the downwardly extending rigid bar portions, and the second rigid upper bar portion is on a second side of the second Y-Z plane. A rigid nose head extends from an end of the second rigid bar portion in a selectable fixable position.
