Patent ES-421373-A1 (ES)
Title: Light-guide communication system with image intensifier repeater elements
IPC: H04B10/29
Filed: 1973-12-11
Abstract: A system for long distance transmission of high bandwidth signals or multiple signals, as for example, in submarine cable service. A high bandwidth signal is split into frequency increments by selective down-conversion for each such increment. A plurality of electrical-to-light transducers are each modulated by the electrical signal corresponding to one of the frequency increments, and a fiber-optic light transmission system transmits each of these transducer outputs to a like plurality of light-to-electrical signal transducers at a receiving end. The multiple outputs from these second transducers are up-converted and mixed together, so that the original wideband signal is recreated. At intervals along the fiber optic waveguide or optical transmission lines used, image intensifiers are used as repeater elements to provide optical amplification.

Title: Large diameter tubular piles and the bedding thereof
IPC: E02D5/80
Filed: 1974-07-08
Abstract: A large diameter tubular pile for bedding into a borehole has an auxiliary tube extending inside it and a series of axially spaced apart holes through its wall which communicate with the interior of the auxiliary tube through discharge pipes which are arranged to allow flow only from the auxiliary tube to outside the pile.
