Patent ES-8500680-A1 (ES)
Title: Delta-sigma modulator with switched capacitor implementation.
IPC: H03M3/00
Filed: 1983-01-20
Abstract: A Delta-Sigma DELTA SIGMA modulator for one-bit analog to digital conversion of a signal, such as a telephone voice channel switch to digital form is disclosed. The circuit incorporates integration operative as low-pass filtering. The voice signal is sampled at a rate high compared to the highest voice channel frequency component. Sampled instantaneous signal values are integrated, re-sampled and again integrated to reduce encoding noise. Finally, a bi-level sense identifying circuit links the second integrator output to a D type flip-flop providing the one-bit encoded output. The sampling and integrator control is effected by switching in a capacitor charge shifting arrangement under clock control and feedback is applied as a capacitor switching program modifications.

Title: Immobilized inorganic diffusion barriers and the use thereof in the separation of small molecular species from a solution.
IPC: C13B20/16
Filed: 1983-02-25
Abstract: The modification of a diffusion barrier by the deposition of one or more inorganic species within the pores and onto the surfaces of said diffusion barrier to form an immobilized inorganic crystalline lattice barrier or molecular grid having substantially uniform permeability, to separate and select different ionic species, giving a high efficiency of separation with a low energy input. The immobilized inorganic diffusion barriers are used for selective separation of small molecules (e,g. molecular weight less than about 1,000 daltons) and provide means for the more effective separation of ionic species.
