Abstract: The present invention consists of an electronic vehicle tag (EVT), which is preferably 12×6 inches. It consists of an encasement mountable by 4 screws to a motor vehicle. The front face is comprised of an electronic paper display technology, which requires no power consumption to maintain its image. The electronic paper display will hold a high resolution full color graphic design relating to the vehicle tag selected and tag information depending on the state of issuances requirements. The display is reflective and can be easily read in sunlight or dimly lit environments and at virtually any angle. The plate has an electronic paper technology for display, wireless communication transmitter/receiver, logic board for electronic paper manipulation, high impact encasement, and a battery pack. The battery pack is used to change the display when required. The electronic vehicle tag is independent of the vehicle in which it is attached.

Abstract: Alkyl 7-deoxy-7-.omega.-substituted alkylthio-.alpha.-thiolincos-aminides useful as intermediates for preparing anti-bacterially active 7-deoxy-7-.omega.-substituted alkylthiolincomycins are prepared by heating alkyl N-acyl-6,7-aziridino-6-deamino-7-deoxy-.alpha.-thiolincosaminides with an appropriate thiol in the presence of an anhydrous lower hydrocarbon carboxylic acid.BRIEF DESCRIPTION OF THE INVENTIONThis invention relates to methods for making alkyl (7R,S) 7-deoxy-7-.omega.-substituted alkylthio-.alpha.-thiolincosaminides of Formula I: ##STR1## wherein Alk is alkyl of not more than 4 carbon atoms, for example, methyl, ethyl, propyl, isopropyl, butyl, sec.- butyl, isobutyl, and tert.-butyl; R.sub.1 is hydrogen, methyl or ethyl; R.sub.2 is hydrogen, methyl or ethyl; R.sub.3 is hydrogen, methyl or ethyl; n is 0 or 1; and R is hydrogen, alkyl of 1 to 6 carbon atoms, inclusive, or aralkyl of 7 to 12 carbon atoms, inclusive.

Abstract: Pharmaceutical compositions of antibiotic U-44,590 and derivatives thereof which can be used to treat Gram-negative and Gram-positive bacterial and viral diseases in humans and animals.

Abstract: Compounds of the formula: ##STR1## are disclosed, wherein R.sub.1 taken independently is hydrogen; R.sub.2 taken independently is the moiety ##STR2## wherein Ac is carboxacyl or an acyl group of formula: ##STR3## wherein Z is hydrogen, lower alkyl or a protective group removable by hydrogenolysis; R.sub.5 is lower alkyl; R.sub.1 and R.sub.2 when together are the divalent group; ##STR4## wherein Z and R.sub.5 are as defined above; R.sub.3 is hydrogen when R.sub.1 and R.sub.2 are taken together and is a monovalent thio group of formula: ##STR5## located in the 7(S)-position when R.sub.1 and R.sub.2 are taken independently, A represents hydrogen or hydroxyl, B represents hydrogen or hydroxyalkyl, n is the integer 0 when B is hydroxyalkyl and n is an integer of 0 to 1, inclusive, when B is hydrogen, X is oxygen .[.or sulfur.]., D is the acyl radical of a lower hydrocarbon carboxylic acid; R.sub.4 is lower alkyl and Y is carboxacyl or hydrogen.
