摘要:
A method for controlling the remanance of a sintered magnet by varying the time when the orienting field is applied during cold compression. The method comprises obtaining powders of an appropriate particle size, compressing the powders in an oriented field, sintering, heat treating, machining and magnetizing to technical saturation. The cold compressing in an orienting field takes place at a precompression rate of more than 15% before the orienting field is applied. The method applies to magnets of all shapes which must have magnetic induction well defined in modulus and in direction, particularly annular magnets for traveling wave tubes.
摘要:
Compounds of the formula ##STR1## in which R.sub.1 is lower alkyl substituted by hydroxy or by protected hydroxy, R.sub.2 represents carboxy or functionally modified carboxy, R.sub.3 is hydrogen, amino, mono- or di-substituted amino, carbamoyl, hydroxy, protected hydroxy, carbamoyloxy, lower alkoxy, halogen, lower alkanoyl, sulphamoyl or heteroarylthio, each of R.sub.4 and R.sub.5, independently of the other, represents hydrogen, lower alkyl, hydroxy, protected hydroxy, lower alkoxy, halogen, amino, protected amino, lower alkanoylamino or carbamoyl, or R.sub.4 and R.sub.5 together represent methylenedioxy, Y represents a group of the formula --O--, --S-- or --NR.sub.6 --, R.sub.6 is hydrogen or lower alkyl, A.sub.1 represents lower alkylene or unsubstituted or substituted phenylene and A.sub.2 represents a direct bond or lower alkylene, and salts of such compounds, have antibacterial activity. The compounds of the formula I are manufactured by processes that are known per se.
