  • Patent number: 6428734
    Abstract: The invention relates to a process for manufacturing injection moulded objects of thermoplastic material by injecting molten thermoplastic material into a mould from at least two distinct injection points whereas the flows of molten material from each injection point each fill part of the mould and flow together to fill the entire mould while still in molten state, wherein objects having a size of more than 80 cm along each of its three dimensional axes are produced by providing at least two distinct injection points at opposite sides of the mould. The invention also relates to injection moulding equipment for the manufacture of moulded objects of thermoplastic material, comprising at least two distinct injection points provided at opposite sides of a single mould assembly. The invention further also relates to three dimensional moulded objects of thermoplastic material having a size of more than 80 cm along each of its three dimensional axes.

  • Patent number: 6407081
    Abstract: The invention concerns a method for inhibiting cytokine production by cells, in particular animal or human cells, and their secretion, which consists in applying on said cells at least an azo compound derivatives corresponding to formula (I), in which A represents a carboxyl or a group (a); B represents a carboxyl or a group (b); R1, R2, R3 and R4=H, Hal, OH or a hydrocarbon radical, R1 and R2 as well as R3 and R4 capable of being a heterocyclic ring; X1 and X2=O or NR5, where R5=H, Hal, a hydrocarbon radical or a nitro group.

  • Patent number: 6271218
    Abstract: Process for inhibiting deoxyribonucleotide triphosphate biosynthesis by cells, comprising application onto these cells of at least one of the azo derivatives of the formula (I), in which R1, R2, R3 and R4=H, Hal, aliphatic or aromatic hydrocarbon or a nitro group, R1 and R2 as well as R3 and R4 being capable of forming a heterocyclic ring with the N adjacent thereto, X1 and X2=0 or NR5, where R5=H, Hal, aliphatic or aromatic hydrocarbon, or a nitro group, and the use of these derivatives for the production of medicines to be administered in conditions which require abnormal production of DNA from the cells

  • Patent number: 5585367
    Abstract: Compositions useful in methods of treating humans and animals infected with viruses of the retrovirus group contain azoic compounds of the general formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are indentical or different and each represents an atom of hydrogen or an aliphatic or aromatic hydrocarbon radical comprising from 1 to 6 carbon atoms, R.sup.1 and R.sup.2 may be bonded together to form a heterocyclic ring with their adjacent nitrogen atom, and R.sup.3 and R.sup.4 may be bonded together to form a heterocyclic ring with their adjacent nitrogen atom; X.sup.1 and X.sup.2 are indentical or different and each represents an oxygen atom or an NR.sup.5 group, wherein R.sup.5 is a hydrogen atom, an aliphatic or aromatic hydrocarbon radical comprising from 1 to 6 carbon atoms, or a nitro group; and wherein when two NR.sup.5 groups are simultaneously present each R.sup.5 may be indentical to or different from the other.

  • Patent number: 5399555
    Abstract: Compositions useful in methods of disinfecting contain azoic compounds of the general formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are identical or different and each represents an atom of hydrogen or an aliphatic or aromatic hydrocarbon radical comprising from 1 to 6 carbon atoms; X.sup.1 and X.sup.2 are identical or different and each represents an oxygen atom or an NR.sup.5 group, wherein R.sup.5 is a hydrogen atom, an aliphatic or aromatic hydrocarbon radical comprising from 1 to 6 carbon atoms, or a nitro group; and wherein when two NR.sup.5 groups are simultaneously present each R.sup.5 may be identical to or different from the other. Compositions containing the azoic compounds in a liquid medium at concentrations of from 35 .mu.gr/ml to 2 mgr/ml are sufficient to impede replication and proliferation of viruses of the retrovirus group yet they are insufficiently toxic to destroy sound human or animal cells which come in contact with the compositions.
