Abstract:
New tricyclic lactones, viz. 10,10-dimethyl-3-oxa[7.1.1.0.sup.2,7 ]undec-2(7)-en-4-one and 10,10-dimethyl-3-oxa-tricyclo[7.1.1.0.sup.2,7 ]undec-4-one. These latter are useful perfuming and flavor-modifying ingredients.
Abstract:
Amorphous magnetic metal alloys are processed by annealing at temperatures sufficient to achieve stress relief and cooling in directed magnetic fields or in zero magnetic fields. The ac and dc properties of magnetic cores produced in accordance with the processes of the invention may be tailored to match those of a wide range of magnetic alloys. Alloys processed in accordance with the invention provide improved performance in inductors, transformers, magnetometers, and electrodeless lamps.

Abstract:
A cobalt-rare earth alloy sintered product is substantially magnetized by heating or cooling it to a temperature at which its intrinsic coercive force H.sub.ci is significantly lower than at room temperature, applying a relatively small magnetizing field to it at such temperature and cooling or warming it in the magnetizing field to room temperature.
