Abstract: A machine for extending a mesh over a laminar material, including a motorless reel holder shaft with an overrun brake, three clamps through which the mesh runs disposed perpendicularly to the movement of the components to be covered, one of these with a disc cutter. The unrolling of the reel is caused by the advance of at least one of the clamps when closed. It features a control unit, a component detection barrier, and elements for the mesh retained to flex prior to being released upon the component, by moving both clamps together. A method for extending a mesh over a laminar material using the aforementioned machine is also provided.

Abstract: Antitumoural compounds of general formula (I); wherein Ar is an heterocyclic group of formula (a) and R1, R2, R3, R4, R5, R6, R7, n and the dotted line take permitted meanings can be obtained from a tunicate of the family Polyclinidae, genus Aplidium, species cyaneum, and the invention further provides derivatives thereof.

Abstract: A nasal pharmaceutical composition incorporates a non-toxic agent which is capable of increasing the ciliary function e.g. caffeine and at least partially antagonizing the ciliary function depressant effect of the active agent e.g. dihydroergotamine or any other constituent present in the composition.

Abstract: Novel nasal pharmaceutical composition adapted to be absorbed systemically through the nasal mucus and comprising as active agent a calcium antagonist selected from optionally substituted, 1,4-dihydropyridines bearing in the 4 position a monocyclic ring, together with a nontoxic pharmaceutically aceptable nasal carrier therefor.
