Abstract: 970,142. Telegraphy. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Nov. 5 1962 [Nov. 10, 1961], No. 41707/62. Heading H4P. In an error-correcting simplex telegraph system in which signals are sent in blocks spaced apart by sufficient time to receive one or other of two answer-back signals, a third answer-back signal is provided so that the direction of main transmission can be altered either on the initiative of the receiver or of the transmitter. If block 1 (a b c) is the last information block to be transmitted, upon reception from the distant receiver Y of answer-back signal R2 transmitter X sends block 2 which is a special signal combination (Cy, +, ?). Receiver Y recognizes this as a request to switch to transmission of information blocks and so transmits the special answer-back signal R3 to inform the station X that it is to switch to reception. Station X now transmits a block of idle-time signals (#α#) which cause Y to transmit a calling signal III and subsequently to transmit information block 1 (p q r) &c. Should the system be non-synchronous the station receiving signal R3-which in this case comprises a sequence of pulses alternately f1 and f2-will open a gate for a preset time to enable this signal to be recognized. If the signal is received mutilated, due to the instants of frequency change occurring in phase with the receiver time base, on repetition it is shifted in phase by “ of an element period. Preferably the answer-back signals are of the form in which one can simulate another only by double transposition. Specifications 930,128 and 970,141 are referred to.

Title: Novel phosphonitrilic compounds and preparation of polyurethanes therefrom
Inventor: LUND LARS GUNNAR
IPC: C08G79/025
Filed: 1961-11-23
Abstract: Polyurethane material is prepared by interacting an organic polyhydroxy compound, an organic polyisocyanate and 1 to 20% by weight based upon the polyhydroxy compound of a cyclic phosphonitrilamidate of the general formula [PN(OR)x(NHR1)y]n, wherein each R is an aryl or halogenated aryl group; each R1 is a hydrogen atom or an alkyl or aryl group; x and y are numbers, which may be fractional, such that x+y=z; and n is an integer of from 3 to 17. Preferably a polyurethane foam is produced by adding a small controlled amount of water with the othere reactants or subsequently to a prepolymer prepared from the polyhydroxy compound and polyisocyanate, optionally with additional polyhydroxy compound or polyisocyanate.  The foaming may be assisted by the addition of a blowing agent, e.g. a fluorinated methane, and/or a cell-controlling agent, e.g. a modified organosiloxane polymer containing oxyalkylene groups.  The preparation is preferably performed in the presence of catalysts, e.g. tertiary amines, organotin compounds and tin carboxylate salts, and surface active agents.  Specified polyisocyanates are toluene and diphenylmethane isocyanates and the polyhydroxy compounds are preferably polyethers, polyesters or polyesteramides; polypropylene glycol being specified in the examples.  Specifications 1,013,462 and 1,013,463 are referred to.ALSO:The invention comprises cyclic phosphonitrilamidates of the general formula [PN(OR)x(NHR1)y]n, wherein each R is an aryl or halogenated aryl group; each R1 is a hydrogen atom or an alkyl or aryl group; x and y are numbers, which may be fractional, such that x + y = 2; and n is an integer of from 3 to 17.  They may be produced by reacting a cyclic phosphonitrilic halide of the general formula [PNX2]n, wherein each X is bromine, fluorine or, preferably, chlorine and n is 3 to 17, successively in any order with (1) one or more metal aroxides, which may be produced in situ, and (2) ammonia or a primary aliphatic or aromatic amine. Said reactions are performed in the presence of an inert liquid diluent and the first stage is performed with such amounts of reactants or under such conditions that the reaction does not occur with all the halogen atoms in the phosphonitrilic halide. The route via phosphonitrilic halidate is preferred.  The isolation of the intermediate product is not essential, but it is desirable to remove at least the by-product metal or ammonium or amine salt from the reaction mixture and, hence, desirable to use a liquid diluent which is a solvent for the phosphonitrilic reactant and products but not for the metal or salt by-products. Suitable diluents are hydrocarbons and chlorinated hydrocarbons. The compounds of the invention may be employed to produce polyurethane materials.  Specifications 1,013,462 and 1,013,463 are referred to.
