Patent ES-346219-A1 (ES)
Title: Code validation system
IPC: H03M13/51
Filed: 1967-10-19
Abstract: Signals of the kind in which each n-bit signal has a fixed number of bits of one state are checked by a circuit which indicates any signal not having that fixed number. Received serial data in two out of five code is stored at 11 and passed in parallel form to resistors 19, 17 so that the potential at the base of Q 2 varies with the number of Mark bits in the signal. Transistor Q 1 is D.C. biased so that Q 2 is saturated or cut off if the base potential of Q 2 is not equal to that corresponding to two Mark bits in the signal. Q 1 , Q 2 are held inoperative by Q 3 until the end of a signal. If the signal is correct Q 1 , Q 2 pass an alternating signal, from unit 14, which is rectified at 22 and energizes relays IR-5R in accordance with the signal stored at 11. The alternating signal will not be passed to the rectifier if either Q 1 or Q 2 fails.

Title: Method for the production of cellulose-based fibres and polynosic fibres having a high resistance to combustion, and fibres and textile articles obtained thereby
IPC: C08L1/00
Filed: 1973-10-26
Abstract: A method is disclosed for producing cellulosic and/or polynosic fibres having flame-resisting properties, the improvement consisting in the fact that a composite viscose is spun in an acidic bath, said composite viscose being obtained by the association in an aqueous solvent, of cellulose xanthate with a phosphorus and nitrogen compound, dissolved in the same aqueous solvent and capable of being converted, while cellulose is being regenerated in said acidic bath, into a state of substantial insolubility. The phosphorus and nitrogen compound is a compound obtained by reacting a phosphonium derivative with aminoacids and amines and/or ammonia. A preferred compound is tetrakis-hydroxymethylphosphonium chloride. By so doing, an efficient flame-retarding protection is obtained for the fibre without sacrificing the physical properties thereof. Critical quantities, reaction conditions and test results are reported.
