Patent ES-477904-A1 (ES)
Title: A system for transporting materials in bulk.
IPC: B65G/
Filed: 1979-02-07
Abstract: The system discussed in this patent is essentially based on raising materials through the combination of multiple individual drives connected to one another and some guidance channels which surround the unit, propelling the individual drives inside the noticeably tubular envelope and in a practically vertical position, so that the bulk materials fed into the lower part are dragged by the different driving elements, transporting them to the upper part where they are unloaded. Each of these driving elements adopts a structure in which it is characteristic that its shape practically coincides with the cross section of the envelope body, so that successive compartments are defined between every two driving elements and the surrounding walls of the enveloping body. In this way it is possible to propel and in particular to raise the mass or bulk materials, of different constitutions and compositions by moving the driving elements connected to one another along the aforementioned envelope.

Abstract: The subject matter relates to an applicator for applying matter to be applied, such as vaccine, to animals. The applicator includes an applicator head which incorporates a chamber and needle. The needle is at least partially surrounded by a generally elongate proboscis or cover which is capable of axial movement over and relative to the needle. A reservoir for matter to be applied or vaccine, is provided and is attached to the applicator head. Valving connects the chamber with the needle and also connects the reservoir with the chamber.
