    Abstract: The present invention relates generally to a combined liquid level indicator for indicating levels of liquid subject to fluctuation and hydrometer means for indicating the specific gravity of the liquid with the device adapted to be mounted in the upper wall of a liquid container, as for example the upper wall of a conventional storage battery. The embodiments of the invention disclosed in the present application include a visual liquid level indicating device having a reflecting surface at the inner end of a transparent body member and the upper end of the transparent body member is adapted to the concentrate light rays reflected from the inner end of the body member from different positions. The liquid level indicator is provided with a groove at its lower end and adapted to receive a pair of identical halves of the hollow body section of the hydrometer means. In another embodiment the hollow body section of the hydrometer means comprise two identical halves which are hinged together to accept a grooved indicator and having a female and male fastening means on the respective halves. The hydrometer means of the various embodiments are provided with chamber means and means for admitting liquid thereto and indicating ball float means operatively mounted within the chamber means for indicating the specific gravity of the liquid within which the hydrometer means is inserted. The different chamber means of the various embodiments comprise substantially parallel and inclined walls between which the indicating ball float means is operatively mounted for indicating the specific gravity of the liquid. When the liquid level of the battery or radiator with which the combined liquid level indicator and hydrometer means is utilized covers the end of the indicator one will obtain a normal black or dark pattern at the upper end. If the specific gravity is low, the orange or red colored ball will not float and will drop down and provide an indicia at the end of the indicator.

    Abstract: A nonmagnetic mounting assembly for maintaining a magnetic deflection yoke in predetermined relationship to the neck of a cathode-ray tube. The mounting assembly is capable of moving said yoke axially relative to the neck of said tube while maintaining a predetermined rotational and/or canted angular relationship between said yoke and neck and also presents the capability of adjusting the angular relationship between said yoke and neck without affecting the axial relationship.
