Abstract
The present invention relates to a method and device for a self orienting floating apparatus which utilizes an external magnetic field to maintain a constant orientation, and specifically relates to a plain form hydrometer, a floating thermometer, and a thermohydrometer that continuously display a graduated scale in an operator pre-determined direction.
Claims24
A self orienting floating apparatus comprising:
- a housing,
- a pin having a first and second end, said second pin end in a fixed relation to said housing;
- said orienting magnet attached to said first pin end, and
- a readout integral with said housing,
- such that when said orienting magnet is aligned with an external magnetic field,
- said readout orients itself in a direction pre-selected by a user, the pre-selected direction being independent of the external magnetic field.

A self orienting floating apparatus comprising:
- a housing having a first end opposed to a second end,
- an orienting magnet attached to a pin, said pin having a first and second end,
- said orienting magnet attached to said first pin end,
- said second pin end affixed within said housing to said apparatus by a means to allow said orienting magnet to resistively rotate,
- and a means to rotate said orienting magnet to a predetermined position,
- such that when said orienting magnet is aligned with an external magnetic field, a
- readout of said apparatus orients itself in a direction pre-selected by a user, the pre-selected direction being independent of the external magnetic field.
4 more elements
A method for orienting a floating apparatus comprising the steps of:
- a) integrating an orienting magnet to said floating apparatus, such that a pin having a first and second end is affixed to said apparatus at said second pin end, said orienting magnet being attached to said first pin end, and
- b) orienting said orienting magnet relative to an external magnetic field such that when said orienting magnet aligns with said external magnetic field, a readout integral to said floating apparatus orients itself in a direction pre-selected by a user, the pre-selected direction being independent of the external magnetic field.
A self orienting floating apparatus comprising:
- an orienting magnet attached to a pin, said pin having a first and second end,
- said orienting magnet attached to said first end, affixing said pin second end to said apparatus so that said orienting magnet will not rotate,
- such that when said orienting magnet is aligned with an external magnetic field, a
- readout of said apparatus orients itself in a direction pre-selected by a user, the pre-selected direction being independent of the external magnetic field.
