Patent ES-8205326-A1 (ES)
Title: Variable window data recovery apparatus and method.
IPC: H04L25/49
Filed: 1981-02-04
Abstract: In a data recovery system, encoded variable spaced digital data is recovered by provision of variable width windows which are expanded or narrowed so as to tend to center upon the expected occurrence of valid data based on knowledge of the contents of the current or the immediately preceding timing units and of characteristics of the encoding scheme. The system employs pulse-to-pulse synchronization without modifying the underlying synchronization of the system such that the first pulse of a two-pulse series serves as a window size reference for an immediately subsequent pulse. The window for a reference pulse is expanded at its trailing edge if, for example, the reference pulse is delayed beyond the tolerance of the detection system. The leading edge of a window for the subsequent pulse is expanded if no pulse occurs within a minimum period following the reference pulse. The encoding technique is particularly applicable to data storage and retrieval systems employing Modified Frequency Modulation (MFM) coding as commonly used in disk drive systems communicating with an input and output controller of a computer.

Patent ES-8401920-A1 (ES)
Title: Method for treating a kaolin clay
IPC: C09C1/42
Filed: 1982-06-14
Abstract: Now in accordance with this invention the above objectives and others which will be obvious in the course of the following description are achieved by a method in which an aqueous suspension with 10 to 20% of kaolin clay solids is subjected to selective rheological separation by mixing the suspension with from approximately 0.001% to 0.1% of a high molecular weight anionic polymer by weight of dry clay. The treated suspension is then separated in a sedimentation stage and a supernatant phase which is produced is substantially free from aggregates. The supernatant phase which contains the improved kaolin pigment in suspension is then separated after the sedimentation stage. The suspended product from the process can be subsequently treated conventionally, e.g. by bleaching, flocculation, filtration and washing, redispersing and then drying or mixing with previously prepared dry material to yield a coating suspension with a high solids content (e.g. 60% to 75% of solids).

Title: Optical fiber drawing using plasma torch.
IPC: G02B6/00
Filed: 1983-06-23
Abstract: In order to provide a high power heat source having a very clean and invariable heat flux, a ring plasma is induced in a heating zone of a plasma torch including a plurality of coaxial tubular elements and the optical fiber is drawn through a channel passing axially through the center of the plasma torch and of the ring-shaped plasma. In this manner the preform from which the fiber is drawn can be placed in close proximity to the induced plasma without exposure to non-symmetrical temperature variations. Cooling gas passes through the heating zone either in an annular stream surrounding the plasma or in an annular stream passing through the center of the plasma around the preform and the fiber being drawn, or both. The heating zone is protected from environmental disturbances by an extension of the outer tubular element of the plasma torch which surrounds the heating zone. The plasma is induced by an RF source in an undisturbed stream of a plasma-forming gaseous medium, such as argon or a mixture of argon with oxygen, which flows through the heating zone.

Title: Optical fibre manufacture
IPC: G02B6/00
Filed: 1985-07-23
Abstract: In an inside tube vapor phase deposition process for the production of doped silica glass by an oxidation reaction for optical fibre manufacture, in particular fluorine doped silica, the oxidation reaction is prevented from occurring until the reactant material, for example silicon tetrachloride and a fluorinating reagent, has been heated to a temperature above that required for the oxidation reaction.
