Abstract: An internal combustion engine comprising at least one flexible cylinder or semicylinder (chamber) formed from (a) at least one flexible, rectangular sheet attached to a rotor, which in turn is connected to a rotatable shaft, and (b) a pair of parallel end plates contacting the sheet's end surfaces and the engine's housing, which plates contain inlet and exhaust ports (valves) for gases and/or liquids, fuel injectors and spark- or glowplugs as well, and the cylinder's volume is periodically varied by at least one roller contacting the flexible sheet's curved surface at radial distances smaller and up to the rotor's (or chamber's) radius, thereby forcing the gases out, or into the flexible cylinder or semicylinder via the ports, respectively.
Abstract: A cheap, compact container for cold-storing beverage or food cans and/or bottles, comprising: (a) a pair of symmetrical, heat-insulating solid blocks with a plurality of semicylindrical indentations therein, spaced at a distance from each other and the boundaries of the blocks; (b) at least one heat-conducting solid foil continuously lining a part of the indentations in either block; (c) at least one heat-absorbing can within an indentation of either block; and (d) fastening means for connecting both blocks so that cylindrical chambers are maintained therein.

Abstract: A pumping or combustion engine having one to four cylindrical or semi-cylindrical chambers formed by at least one flexible sheet attached to a rotor, which sheet and/or rotor contact a plane, rigid plate at both sides thereof, containing inlet and exhaust ports for gases and/or liquids therein, which ports are opened and closed by the sheet, rotor, and/or spring-loaded check valves; and the volume of each chamber is varied when flexing the sheet by the reciprocal or rotational momentum of the rotor(s) alone, or its rotation along outer or inner, stationary or moveable, spring-loaded rigid cylinders (rollers).
Abstract: 19-Oxygenated steroid compounds of the pregnane series of the formula I ##STR1## in which R.sup.1 represents a hydrogen atom, andR.sup.2 represents an .alpha.-oriented lower alkanoylthio group, orR.sup.1 and R.sup.2 together represent a carbon-carbon bond or an .alpha.-or .beta.-oriented methylene radical,R.sup.3 represents a free hydroxymethyl group or a hydroxymethyl group etherified by a lower alkyl or esterified by a lower alkanoyl; or represents a formyl group, a carboxyl group or a lower alkoxycarbonyl group, andR.sup.4 represents a hydrogen atom or the acyl radical Ac of a carboxylic acid,and corresponding 1,2-dehydro derivatives have valuable aldosterone-antagonizing properties with a minimum effect on sexual functions. As the compounds reduce the excessive sodium retention and potassium excretion induced by aldosterone, they are especially useful as the active ingredient in pharmaceutical preparations for alleviating diseases involving hyperaldosteronismus in man and other warm-blooded animals.
Abstract: The invention relates to novel ortho-aminoacetophenones of the formula I ##STR1## and their tautomers, in which Z is hydrogen, halogen, lower alkyl, cycloalkyl, lower alkoxy, trifluoromethyl, nitro or substituted or unsubstituted sulphamoyl, m is 1 or 2, R is hydrogen, aryl or lower alkyl, R.sub.1 is hydrogen or lower alkyl, R.sub.2 is lower alkyl, cycloalkyl, aryl, cycloalkyl-lower alkyl, aryl-lower alkyl or substituted or unsubstituted pyridyl, R.sub.

Abstract: An advantageous diuretic action by excretion of water, sodium and chloride ions, with reduced excretion of potassium ions, is effected by combined administration of a 19-oxygenated steroid compound of the pregnane series of the formula ##STR1## wherein R.sub.a represents a hydrogen atom, andR.sub.b represents an .alpha.-oriented lower alkanoylthio group, orR.sub.a and R.sub.b together represent a carbon-carbon bond or an .alpha.- or .beta.-oriented methylene radical,R represents a free hydroxymethyl group or a hydroxymethyl group etherified by a lower alkyl or esterified by a lower alkanoyl; or represents a carboxyl group or a lower alkoxycarbonyl group, andR.sup.2 represents a hydrogen atom or the acyl radical Ac of a carboxylic acid,as the aldosterone-antagonising component A on the one hand, and, on the other hand, of a conventional diuretic which is unspecific in respect of electrolyte excretion, e.g.
Abstract: N-(diphenylmethoxy-mono- or bicyclic-alkyleneiminoalkyl)-dicarboximides, e.g. those of the formula ##STR1## A=aliphatic or cycloaliphatic radical R,R'=H, alkyl, halogen or CF.sub.3R"=H or both are ethyleneq=2-4and salts thereof are antiallergics and antiasthmatics.
Abstract: The present invention provides new benzofuranyl-tetrahydropyridines and -piperidines of the general formula I ##STR1## in which R.sub.1 and R.sub.2 independently of one another are hydrogen or lower alkyl or together are lower alkylene, R.sub.3 is hydrogen, lower alkyl, lower alkenyl, lower alkynyl, cyclo-lower alkyl or cyclo-lower alkyl-lower alkyl and Y.sub.1 and Y.sub.2 are each hydrogen or together are an additional bond, and the ring A is not further substituted or is further substituted by lower alkyl, lower alkoxy, halogen with an atomic number not more than 35, cyano or hydroxyl and the pharmaceutically acceptable acid addition salts thereof, and antidepressant preparations containing these compounds.

Abstract: The invention relates to the preparation of polyhalogenated pregnane derivatives of the formula ##STR1## wherein X represents fluorine or chlorine and R a free or esterified hydroxyl group or chlorine. The new compounds display a high antiinflammatory activity. No side action on the thymus, the body weight or the adrenals can be detected at the therapeutic dose when the compounds are administered topically. The new compounds are therefore particularly suitable for use as medicaments in dermatology.The new compounds can be prepared according to methods known in the art, e.g. by introducing the chlorine atom in 2-position of corresponding compounds which are non chlorinated in this position, or by the introduction of the halogen atom in 9-position starting from the 9,11.beta.-epoxide or the 9,11-dehydro-compound or by acetonization of the 16,17-dihydroxy group or by replacing a 21-hydroxy group by chlorine.
