Abstract: A gas-insulated switch has a first contact and a second contact. A contact unit is connected to the first contact as a movement contact unit having a drive unit and is movably mounted along a switch axis. The gas-insulated switch further has a multi-part insulation nozzle system with a primary nozzle and an auxiliary nozzle. A heating channel is formed between the primary nozzle and the auxiliary nozzle. The heating channel originates from an electric arc chamber and opens in a gas reservoir, wherein the gas reservoir is delimited by a ram. The gas reservoir is radially delimited by a wall, in respect of the switch axis, which is not a component of the movement contact unit, and the ram is part of the movement contact unit and is movably mounted such that the ram moves along the switch axis away from the second contact to enlarge the gas reservoir.

Abstract: A high-voltage circuit breaker system has a rapid disconnection function that results in an opening, closing, and reopening movement of a contact system. A circuit breaker having the contact system and a drive system that is mechanically connected to the contact system. The drive system includes a drive unit and, in addition to the drive unit, a drive shaft that is designed as a crankshaft. The crankshaft is connected to a mobile contact of the contact system via a push rod, and the cycle of opening, closing, and reopening movement of the contact system results from a unidirectional rotational movement of the crankshaft.

Abstract: The invention relates to the field of hearing aids and earphones. More specifically, the invention relates to a universal adapter for earphones and hearing aids worn in the ear. The universal adapter serves for the introduction of amplified sound of a hearing aid or earphone into the auditory canal, wherein the adapter has trapezoidal hollow segments (5) which are arranged separate from one another, with their side walls (15) that radially decrease from the dorsal to the proximal side, along a centrally arranged locking nipple (2) which serves to receive a sound outlet connector of the hearing aid. The hollow segments (5) are connected with the proximal ends (14) of the contact surfaces (1) to a proximal end (6) of the locking nipple (2). The adapter has the shape of a shortened ellipsoidal body. It can automatically adapt to the shape of the auditory canal.
