Abstract: A three-axis seismometer in which three masses are suspended for essentially frictionless movement within certain directions in magnetic fields. Detecting means sense movement of the masses and generate signals used to actuate feedback means. The amount of feedback required is used as a measure of seismic motion. Since motion sensing and the measurement of the magnitude of the motion are separated, output of the instrument may be linear. Responses in unwanted frequency ranges may be filtered out.

Abstract: New norcamphane derivatives bearing at the 3-position a 2hydroxyethylamino, 2-haloethylamino, ethyleneimino, or cyclopropylmethylamino group, having useful hypotensive activity, and prepared, respectively, by alkylation of 3-amino-2,2,3trimethylnorcamphane with ethylene oxide; halogenation of the resulting 3-(2-hydroxyethylamino)-2,2,3-trimethylnorcamphane; cyclization, in the presence of alkali, of the resulting 3-(2haloethylamino)-2,2,3-trimethylnorcamphane; or acylation of 3amino-2,2,3-trimethylnorcamphane with a cyclopropylcarbonyl halide and alkali metal aluminum hydride reduction of the resulting 3-cyclopropylcarbonylamino-2,2,3-trimethylnorcamphane.
