Abstract: A method is provided for braking a motor vehicle equipped with wheel brakes without a hydraulic connection to a brake-operating device, and with a service brake unit having a brake actuator, which, triggered by an output signal of the brake-operating device and ultimately with the aid of a control device, loads the wheel brakes in a wheel- or axle selective manner so that the braking force changes at least on one wheel or at least on one axle. The method is characterized in that a total setpoint braking force that decelerates the motor vehicle is distributed via the brake actuator to the individual wheels or axles by the control device.

Abstract: 2',3'-dideoxynucleoside pyrimidine compounds and 2-thiothymidine carbocyclic derivatives with antiviral activity are disclosed. These compounds are expected to exhibit antiviral activity recognized for 2',3'-dideoxynucleoside compounds and analogs thereof.

Abstract: Compounds of formula I ##STR1## in which R denotes a straight-chain or branched, saturated or unsaturated aliphatic hydrocarbon radical having 6-30 C atoms wich may optionally be substituted by halogen or the radicals OR.sub.1, SR.sub.1 or NR.sub.1 R.sub.2, where R.sub.1 and R.sub.2 in each case denote a hydrogen atom or an alkyl or acyl radical having 1-6 C atoms which have excellent virustatic and cytostatic action.

Abstract: A process for treating AIDS, which comprises administering to a patient in need therefor a pharmaceutical composition comprising a therapeutically effective amount of a compound having the formula ##STR1## wherein: R.sub.1 is an adenine, cytosine, guanine, thymidine, uracil, 5-substituted uracil, 5-substituted cytosine derivative, 2-fluoroadenine, 2.6-diaminopurine, 2-aminopurine, 6-thioguanine, or 7-deazaadenine group;R.sub.2 is H, or a OH group;R.sub.3 is a OH, O-acyl, O-palmitoyl group or phosphates (as free acid, or its alkali, ammonium or alkyl ammonium salts), or any other precursor group for the hydroxyl group;or a physiologically acceptable salt thereof.

Abstract: The invention relates to novel glycero-3(2)phospho-L-serine derivatives of the general formula ##STR1## in which A represents unsubstituted or substituted (C5-C30) alkoxy, or unsubstituted or substituted (C5-C30) alkenoxy, whereby a double bond of the alkenoxy residue does not originate at the C atom bound to oxygen, or halogen, or a group of the general formula--O--(CH.sub.2).sub.n --CF.sub.3 II,wherein n is 0 or an integer 1, 2 or 3, one of the two residues B and C, which is identical to or different from A, has one of the definitions given for A or represents hydrogen, and the respective other residue represents the phosphatidyl-Lserine group of the formula ##STR2## with the proviso that at least one residue A, B or C represents (C5-C30) alkoxy or (C5-C30) alkenoxy; and the pharmaceutically acceptable salts of compounds of general formula I with bases, a process for the preparation thereof, pharmaceutical preparations containing the said compounds, and their use in drugs with cytostatic activity.

Abstract: A feed pipe for conveying sticky bulk material from a bunker outlet vertically downward to a conveyor apparatus wherein the feed pipe is comprised of a plurality of truncated conical sections tapering downwards, the axial length and the diameter of the tubular sections being dimensioned such that arching of the bulk material is avoided.
