  • Patent number: 9364381
    Abstract: A casket carrying device that is designed to allow for much easier transporting of the coffin from a funeral to a graveside service allowing it to be maneuvered more easily, even up and down flights of stairs as necessary. The handle members may be about five inches wide. The handles may have two top slightly curved portions measuring about two inches across. The handy handle features a pivot rod about 18 inches in length and 1-1½ inches in diameter that allows for the handle to be used on either side of the casket. The handle may fold when not used (when not in extension) to become parallel with the casket. The handles when properly used put less strain on the casket bearers since they provide functionally accessible handles.

  • Patent number: 4101579
    Abstract: Compounds of the general formula I and physiologically acceptable acid addition salts thereof:- ##STR1## in which R.sup.1 is a lower alkyl, lower alkenyl, or arylalkyl radical, which radicals may optionally be substituted by one or more alkoxy or hydroxy groups.R.sup.2 represents a hydrogen atom or a lower alkyl radical which may optionally be substituted by one or more hydroxy groups, amino groups, or heterocyclic rings containing one or more heteroatoms, or R.sup.2 represents a cycloalkyl, arylalkyl or aryloxyalkyl radical, which radicals may optionally be substituted by one or more alkoxy or hydroxy groups;R.sup.3 represents a hydrogen atom or a benzyl group;X represents a group of formula --CONR.sup.4 R.sup.5 where R.sup.4 and R.sup.5 may be the same or different and each represents hydrogen or a lower alkyl group;With the proviso that when R.sup.2 is tertiary butyl and R.sup.1 is a benzyl group, R.sup.3 represents a hydrogen atom. The compounds have a blocking action on .beta.

  • Patent number: 4066755
    Abstract: Compounds of the formula: ##STR1## and physiologically acceptable acid addition salts thereof, in which R.sup.1 isA. an arylalkyl group, the alkyl portion of which contains from 1 to 6 carbon atoms and the aryl portion of which may be substituted by one or more alkoxy groups or hydroxy groups; orB. an aryloxyalkyl group, the alkyl portion of which contains from 1 to 6 carbon atoms, and the aryloxy portion of which is substituted with one or more alkoxy or hydroxy groups.These compounds have a blacking action on both .alpha.- and .beta.-adrenergic receptors and are useful in treating hypertension. Processes for the production of these compounds and pharmaceutical compositions containing them are also provided.

  • Patent number: 4000193
    Abstract: Compounds of the formula: ##STR1## in which: R.sub.4 and R.sub.5 independently represent hydrogen or lowr alkyl;R.sub.6 represents a straight or branched alkyl or alkenyl group containing from 4 to 6 carbon atoms, inclusive, orR.sub.6 represents a straight or branched alkyl group containing from 2 to 6 carbon atoms, inclusive, which alkyl group is substituted by one or more hydroxy, alkoxy or acyloxy groups; or by an aryl group which may be substituted by one or more hydroxy, alkoxy or acyloxy groups as before; andR.sub.7 represents a straight or branched alkyl group containing from 3 to 6 carbon atoms, inclusive, optionally substituted by an alkoxy group or by an aryl or aryloxy group which, alkoxy, aryl or aryloxy group may, in turn be substituted by hydroxy, alkoxy, acetamido or methanesulphonamido groups,And pharmaceutically acceptable salts thereof. These compounds have utility in the treatment of cardiovascular diseases.
