Abstract: A rotor for an electric machine has a rotor member extending circumferentially about the axis of rotation of the rotor, and a locking device in an axial end region of a guide to mount permanent magnets in the direction of the axis of rotation of the rotor. The locking device is retained on the rotor member in the radial direction and in the direction of rotation of the rotor by guides. The locking device has a movable movement element and is designed such that when the movement element is moved, the locking device is positively or non-positively connected to the rotor member.

Abstract: A submarine is provided with an upwardly directed drilling device (12, 12?). The drilling device (12, 12?) is arranged in a pressure hull (4) of the submarine and has a drill (14, 14?) which can be extended out of the pressure hull (4) through an opening (10) arranged on the upper deck of the submarine. The drill has a drilling head (42, 42?) which forms a closure body which closes the opening (10) of the pressure hull. The drill functions to drill a hole from under an ice sheet to allow occupants of the submarine to exit through the hole.

Abstract: An operating device for a vehicle has operating elements for operating different electrical equipment such as, for example, a navigation device, an audio system, a heating and/or air conditioning system and/or a telephone. In order to permit the driver of a vehicle to operate such units as conveniently as possible, and to avert his attention as little as possible during driving operation, it is proposed to design the operating device such that the operating device has a support body that prescribes a fixed position of the operating hand and has operating elements in the form of a control wheel and keys surrounding the control wheel. The keys are arranged in an operating plane such that they enclose an obtuse angle with the support surface formed by the support body.
