    Abstract: The invention relates to a method for manufacturing barber scissors, wherein the scissor blades are pre-shaped from blanks by a predetermined degree of curvature in the direction facing away from the edge. This is followed by a step of welding on a hard metal material in the form of a welding bead on respective mutually facing faces of the scissor blades in order to form the edges, wherein the preliminary curvature of the scissor blades is neutralized owing to the influence of heat during the welding process. Subsequently the welding beads are ground so as to form the edges, and the scissor halves are pre-set and hardened. Then the barber scissors are hard-set in the assembled condition. The invention furthermore relates to barber scissors having such a configuration. Here the edges are present as massive material over the entire thickness of the scissor blades, so that even severally repeated re-grinding or re-setting of the barber scissors is possible without any loss of functionality.

    Abstract: An electronic valve control system is used to optimise the operation of fluid cycle of a Stirling engine. The valves control the flow between an external heater and cooler. The Stirling engine has four non return valves located in the heater (1) and cooler (3) regions at the top of the piston chambers with the regenerator (2) in between. The operation of the valves at the correct times is provided by a computer system.

    Abstract: The invention relates to a method for the production of hairdresser's scisso rs (1), wherein the scissor blades (23,33) are pre-deformed from blanks accordi ng to a specific degree of curvature in the direction facing away from the cutting edge. A hard metal material is then respectively welded in the form of a welding pass to the front faces of the scissor blades (23,33) which are directed towards each other in order to form the cutting edges (24,34). The curvature of the scissor blades (23,33) recedes as a result of heat action during the welding process. The welding passes are then ground in order to form cutting edges (23,24) and the scissor halves (2,3) are pre-straightened and are hardened. The hairdresser's scissors (1) are then straightened when hard in an assembled state. The invention also relates to hairdresser's scissors thus embodied. The cutting edges (24,34) are provided in the form o f a full material extending along the entire thickness of the hairdresser's scissors (23,33), such that post-grinding or further straightening of the hairdresser's scissors is possible without incurring any losses in terms of functionality.
