Abstract: A hanger for arranging a curtain, flag or cover for movement in a plane defined by a displacement axis and the hanger being arranged symmetrical with respect to the displacement axis, which comprises a guide rail, a guide element guided by the guide rail, a support body connected to the guide element, the support body having two legs arranged to overlap an edge of the sheet held therebetween, and the edge of the sheet being affixed to the support body.

Abstract: To simplify playing of an electronic instrument and to avoid the otherwise clearly recognizable synthetic sound quality, the operating elements are arranged in a wind or blowing body constructed and playable similar to a mouth-harmonica. These operating elements comprise a pressure sensor responsive to the blowing and suction air current or stream of a human being and which is coupled to a mouthpiece displaceable along the wind or blowing body, and a number of position sensors which respond in accordance with the momentary position of the mouthpiece. The pressure sensor and the position sensors are coupled to an evaluation circuit which is structured such that it generates, as a function of the response of these sensors, the control voltages required for controlling the synthesizer.
