Abstract: Apparatus for the soundproofing of moving picture cameras with a soundproof mounting of the camera skeleton supporting the parts of the camera mechanism which generate noise and vibrations in a camera housing, which has a lens holder, to which interchangeable lenses can be fastened, whereby for the soundproof mounting of the camera skeleton in the camera housing, there are several soundproofing connecting elements between the camera skeleton and the camera housing, at least some of which have a directional natural rigidity.

Abstract: This invention relates to a self-aligning bearing for a precision measurement pendulum, in which, between the pendulum and a housing, there are two magnetic bearings, one each on either side of the pendulum, each of which has a bearing ring magnet. The magnetic bearing on the one side of the pendulum has a pole pivot for magnetic centering, opposite which is the pole pivot of a soft iron core. The magnetic bearing located on the other side of the pendulum has a spacer as a mechanical stop, in which there is a tension wire or band stretched between the pendulum and the housing. The magnetic bearings generate magnetic fields of like or unlike polarity extending in the direction of the pendulum axis of rotation, rotationally symmetrically around the latter, and magnetic fields of unlike polarity extending radially to the pendulum axis of rotation, and radially symmetrical to it. The precision measurement pendulum can be used advantageously in a highly-sensitive bearing for measurement purposes.
