Abstract: The invention relates to a method for managing a display device (DSP) of a portable communications device (MFG) having the following characteristics: said display device is used for displaying graphical subject matter, it also comprises a processing device (LAE) for carrying out first and second applications, each of which has an output subject matter. A control device (IM) for managing the graphical display surface of the display device is also provided, wherein the control device of the first application allocates a first display area and the control device of the second application allocates a second display area in such a way that no overlap of said display areas is produced, thereby avoiding the harmful influence of the first performed application on the second later invoked application.

Abstract: Disinfectant compositions, containing (a) at least one amine and/or quaternary ammonium salt of the general formula (Ia) or (Ib): wherein R1 represents C6-18 alkyl, R2 represents benzyl or C6-18 alkyl, R3 represents C1-18 alkyl or —[CH2)2—O]nR6, where n is 1 to 20, R4 and R5 independently of one another represent C1-4 alkyl, R6 represents hydrogen or optionally substituted phenyl and A? is a monovalent anion or the equivalent of a multivalent anion of an inorganic or organic acid; and (b) at least one alkanolamine of the general formula (II): wherein m and, if present, o and p independently of one another have the values 2 or 3 and x and y independently of one another have the values 0 or 1, or a corresponding salt. The mass ratio of the components in the formulas (I):(II) is between 20:1 and 1:20.

Abstract: Process for utilizing the disinfectant composition as a virucidal agent. The disinfectant composition includes: (a) an amine and/or quaternary ammonium salt of the general formula: where R1 is C6-8-alkyl, R2 is benzyl or C6-18-alkyl, R3 is C1-18-alkyl or —[(CH2)2—O]nR6 where n=1-20, R4 and R5 independently of one another are C1-4-alkyl, R6 is hydrogen or unsubstituted or substituted phenyl, and A? is a monovalent anion or one equivalent of a polyvalent anion of an inorganic or organic acid; and (b) at least one alkanolamine of the general formula: where n and, if present, m and o independently of one another have the value 2 or 3, and x and y independently of one another have the value 0 or 1, or a corresponding salt; in the mass ratio of (a) to ( )b) of 20:1 to 1:20.

Abstract: A fungicidal composition of disinfecting and preserving agents, including at least both an amine and/or quaternary ammonium salt of the general formula 1
