Abstract: The disclosure is directed to a side gate nozzle (1). The side gate nozzle (1) usually comprises a supply block (2), a distribution block (3) and a nozzle block (4) inter-connected to each other in an axial direction (z). The nozzle block (4) comprises at least one nozzle recess (5), in which a nozzle insert (6) is arranged. The nozzle insert (6) is in the axial direction (z) held by an individual set screw (7) directly or indirectly interconnected to the nozzle block (4).

Abstract: The invention relates to a polypeptide containing in its polypeptidic chain: the amino acid sequence of 101 amino acids of FIG. 8, or a fragment of this sequence, this fragment being such that it is liable to be recognized by antibodies also recognizing the abovesaid sequence of 101 amino acids, but it is not recognized by antibodies respectively raised against M. bovis, M. avium, M. phlei and M. tuberculosis, and possibly against M. leprae, M. intracellulare, M. scrofulaceum, M. fortuitum, M. gordonae and M. smegmatis; it is liable to generate antibodies which also recognize the abovesaid sequence of 101 amino acids but which do not recognize M. bovis, M. avium, M. Phlei and M. smegmatis; it reacts with the majority of sera from cattle suffering from Johne's disease; or the polypeptidic sequences resulting from the modification by substitution and/or by addition and/or by deletion of one or several amino acids in so far as this modification does not alter the above-mentioned properties.

Abstract: Derivatized type A virginiamycins having a reactive functionalized side chain, and a process for making the virginiamycin derivatives. The side chain contains a thioether linkage and a reactive group, such as a carboxylate ester or free carboxylic acid group.

Abstract: The invention synergimicin derivatives having the general formula: Z--X--R, in which Z is a type A or type B synergimycin radical linked by its reactive carbonyl position, through a branch X, where X is .dbd.N-- or .dbd.N--O--, to a substituted R, where R is a hydrogen atom, an alkyl group, an alkyl-COOH group, an -alkyl-(.alpha.NH.sub.2)COOH group (I), group (II), group (III) or a group (IV), where n is a function of the number of --NH.sub.2 groups present on the coupling protein. Also described are the salts, esters and possibly addition products of pharmaceutically acceptable acids. The invention also concerns a process for preparing these substances, and their use.
