Abstract: Phenothiazines of the formula: ##STR1## where R.sub.1 is H or --COOR, where R is selected from the group consisting of branched or unbranched alkyl groups containing from 1 to 4 carbon atoms, and where X is selected from H, branched or unbranched alkyl groups containing from 1 to 4 carbons, and halogen, and pharmaceutically acceptable salts thereof. Particularly preferred phenothiazines are those wherein X is hydrogen, chloro, bromo or methyl, R.sub.1 is COOR, and R is methyl, ethyl or t-butyl.

Abstract: The present invention concerns enaminones having the formula: ##STR1## wherein R is COOCH.sub.3 ; R.sup.1 is CH.sub.3 ; R.sup.2 is H; and R.sup.3 is selected from the group consisting of C.sub.6 H.sub.4 (p-Cl) and CH.sub.2 C.sub.6 H.sub.5.

Abstract: An oxazolyl enaminone is provided having the formula: ##STR1## wherein R.sub.1 is selected from the group consisting of a branched or unbranched alkyl groups containing from 1 to 4 carbon atoms and R.sub.2 is selected from the group consisting of a branched or unbranched alkyl group containing from 1 to 4 carbon atoms, a chloro group, a trifluoromethyl group and a trifluoromethoxy group. Also provided are pharmaceutically accepatable salts and isomers of the above, and pharmaceutical compositions containing the same.

Abstract: The present invention concerns enaminones having the formula: ##STR1## wherein R is from the group consisting of COOCH.sub.3 and COOC.sub.2 H.sub.5 ; R.sup.1 is from the group consisting of H and CH.sub.3 ; R.sup.2 is from the group consisting of H when R.sup.1 is CH.sub.3 and CH.sub.3 when R.sup.1 is H; and R.sup.3 is from the group of first radicals consisting of benzyl, phenethyl, disubstituted phenyl and trisubstituted phenyl. The substituted species are second radicals having positive lipophilicity selected from the group consisting of F, Cl, Br, and I.

Abstract: A VHF radio (10) which includes an adjustable antenna (20) formed from a component (28) shaped like an open helical compression spring which engages and can be screwed into a metal supporting collar (40) for tuning the antenna (20). An elongated plastic or rubber cylindrical member (30) is connected to the metal collar and surrounds at least a portion of the helical member (28). An end cap (32) is provided for closing the other end of the cylindrical member (30).

Abstract: A drum is used to wind and unwind conductors that comprise the elements of an adjustable dipole antenna. The length of the elements is adjusted by rotating the drum. As the elements are unwound, they extend into tubular TEFLON guides that provide support for the elements.
