Patent ES-437103-A1 (ES)
Title: Transparent time-division pulse-multiplex digital electric signal switching circuit arrangement
IPC: H04J3/06
Filed: 1975-04-28
Abstract: Bilevel or bistatic digital electric signals are transmitted directly through a time division multiplexing (TDM) switching component asynchronously of the TDM clocking pulse train. A pulse duration modulated (PDM) electric signal or like wave is converted to a pulse amplitude modulated (PAM) electric wave having amplitude and timing components indicating a predetermined relationship to the TDM sampling period. The input PDM wave is amplitude limited by conventional circuitry and phase relationship is indicated by a ramp wave generator or a digital counter with the slope of the ramp wave or the counting rate proportional to the sampling period. Other forms of analog-to-digital converter circuitry may be substituted. The converted PAM electric wave is then passed through the switching component in conventional manner. Thereafter, the switched PAM electric wave is analyzed for reconstructing the original PDM electric signal wave. Complementary circuitry is preferably used for regenerating the signal. The upper limit on the data rate corresponds to one transition of the input electric signal to one time division sampling period of the TDM switching component.

Title: Manufacture of cheeses
IPC: A23C19/02
Filed: 1977-02-03
Abstract: Cheese is produced by a process wherein milk is subjected to partial ultrafiltration, heat denatured serum proteins are added to the milk before or after ultrafiltration, the milk is coagulated to form a curd wherein 1/4 to 1/2 of the total serum proteins contained in the curd are the added heat denatured proteins, and the curd is drained to produce curd containing a total amount of serum proteins substantially equal to the total serum protein content of the starting milk.

Title: Process and device for online dehydrogenation of fibre-drawing preforms.
IPC: C03C13/00
Filed: 1982-06-15
Abstract: Vapor deposition of doped silica in a reaction chamber on a rotating supporting surface, in the manufacture of a preform for the drawing of an optical fiber, is accompanied by the continuous admixture of deuterium with a flow of carrier gas, specifically oxygen, by which the reactants are transported to the reaction chamber. An isotopic substitution of deuterium for the hydrogen of hydroxyl groups in the reaction products shifts the major absorption peaks to wavelengths outside the minimum-attenuation range of 0.7 to 1.6 mu used for fiber-optical signaling. The proper ratio of deuterium to carrier gas is maintained with the aid of a mixer having two compartments separated by a perforated diaphragm or a thin metallic foil, one compartment being connected to a deuterium tank while the other communicates with a conduit through which the vapors entrained by the carrier gas pass to the reaction chamber.
