Abstract: A precessionally aligned automatic scanning system is provided. It consists of a free spinning means which scans an electromagnetic field of radiation having lines of force whose angle of incidence is to be determined with respect to the axis of rotation of the free spinning means by detecting the angle of incidence between the axis of rotation of the free spinning means and the direction of the lines of force from the electromagnetic field of radiation. This provides an unresolved error signal representative thereof. In addition, means are provided for receiving the unresolved error signal and utilizing the unresolved error to precess the free spinning means through gyroscopic forces to cause the axis of rotation of the free spinning means to align itself with the lines of force of the electromagnetic field of radiation.

Abstract: A free spinning gyroscope is provided which has a spin axis, together with precession means for precessing the gyroscope. In addition, means are provided for detecting an electromagnetic field of energy and adapted to generate signals indicative of misalignment of the gyroscope spin axis with the energy field. Means are provided for utilizing the generated signals to directly control the precessing means to align the gyroscope spin axis with the electromagnetic field of energy.

Abstract: An improved tire chain in which the chain length on the inner side of a tire may be remotely connected by means of a releasable connecting means. The releasable connecting means is initially engaged with a hook and a connecting link on the inner side chain, and a pull on its handle causes the hook to engage with the connecting link. In a preferred embodiment, the connecting means automatically disengages from the chain.

Abstract: A free spinning gyroscope is provided which has a spin axis, together with precession means for precessing the gyroscope. In addition, means are provided for deflecting an electromagnetic field of energy and adapted to generate a signal indicative of misalignment of the gyroscope spin axis with the electromagnetic field of energy. Mechanism is further provided for utilizing an unresolved signal for directly controlling the precession means to maintain the gyroscope spin axis in alignment with the electromagnetic field of energy.

Abstract: A terminator and grounding device particularly for an underground distribution cable having a concentric grounded neutral. A deformable metal sleeve has an annular space between side wall portions thereof to receive and terminate the helically wound neutral conductor. A steel liner in the deformable metal sleeve resists crushing and provides a through passage for the insulated distribution conductor. A tubular deformable metal side gripper on the main sleeve receives an extrinsic ground wire.
