Title: Time division multiplex communication
IPC: H04J3/16
Filed: 1971-09-16
Abstract: 1357150 T.D.M. exchange systems; data transmission INTERNATIONAL BUSINESS MACHINES CORP 16 Sept 1971 [30 Sept 1970] 43157/71 Headings H4K and H4P In a system for channel switching between a plurality of incoming and a plurality of outgoing T.D.M. highways, two time slots of each frame on each highway are used jointly to provide a single channel reserved for signalling (dialling &c.) and data transmission, one time slot of each pair being used for signals or data the other being used to transmit an associated subscriber address. The system shown switches between incoming and outgoing P.C.M. highways 25 and 27. The highways may be loops (Fig. 1, not shown) on which subscriber station 11a to 11c and T are located. The stations may include speech telegraph and video equipment. The incoming highways 25 are scanned by a scanner 29 (described below) to produce a succession of P.C.M. codes in parallel form on output 53 to AND gate groups 59, 81 and 71 and for each code a corresponding highway time slot number on an output 55 to a decoder 57. If the decode recognizes that this is the first time slot of that highway frame it enables via P1 AND gate group 71 to feed the code from that time slot into an intermediate store 75 where it is held until that highway is due to be scanned again. The code used in the first time slot includes an address of the calling station, a flag bit indicating whether the code in the other time slot of the pair is a signalling code or data for onward transmission and a parity bit. When an incoming highway is scanned a second time the decoder 57 recognizes that the second time slot is being scanned and enables via P2 AND gate group 81 to gate the code in that time slot on to bus 83. At this time the code taken from time slot 1 of that incoming highway appears at the output of store 75 and depending on whether the signalling bit is a "1" or a "0" AND gate groups 89 and 91 or an AND gate group 103 is enabled. In the former ease the calling subscriber address and the signalling code (e.g. dial signal code) are transferred to registers 93 and 95 for interpretation by the exchange control unit 101 while in the latter case the calling subscriber address from store 75 is used to address a store 107 to obtain the address of the called subscriber, this being used to gate itself and the data code on bus 83 into queueing stores such as 121a and 121b associated with the outgoing highway.

Title: Urea synthesis
IPC: C07C273/04
Filed: 1960-12-16
Abstract: Urea is prepared by reacting CO2 with NH3 in a reactor, passing the liquid reaction mixture from the reactor to a separation zone wherein water and unreacted gases are separated as a vaporous fraction from the liquid urea, passing the vaporous fraction to a primary condensation zone wherein water containing a small amount of ammonia (preferably not more than 5%) is condensed under conditions such that the formation of an equilibrium mixture is avoided (e.g. by condensing out the water at a gradually decreasing temperature and immediately separating it from residual NH3 and CO2), passing the vapours from the primary condensation zone to a secondary condensation zone wherein the unreacted components are condensed to form an equilibrium mixture, and recycling the condensate to a previous process step so that at least a portion of the condensate is recycled directly or indirectly to the urea reactor.  Preferably the reactor effluent is passed to a carbamate condenser wherein unreacted components are separated from liquid urea as vapours and condensed as aqueous ammonium carbamate which is recycled to the urea reactor, the condensate from the equilibrium mixture being passed to the carbamate condenser.  Two carbamate condensers may be used in series, the condensate from the second being recycled to the first.  Preferred operating conditions are specified.

Title: Elastomers suitable for application by spraying
IPC: C08G18/10

Abstract: Polyether-polyurethane-polyureas are prepared by intimately mixing a polyether-polyurethane, prepared by reaction of at least one polyether polyol with a stoichiometric excess of a polyisocyanate in a ratio of NCO:OH of 1.5-3.0:1, and having a viscosity of 4000-20,000 centipoises at 25 DEG  C., with a diamine in an inert volatile solvent, in proportions such that the ratio of NH2:OH>0.5:1 and NC:(OH+NH2) is 0.95-1.6:1, these ratios being calculated on the basis of the polyol, polyisocyanate and diamine starting materials. Suitable polyether polyols are polyethylene- and polypropylene-glycols and ethoxylated or propoxylated trimethylolpropane, glycerol, hexane triol or pentaerythritol, mixtures having M.W. 400-4000 on average are preferred.  Suitable polyisocyanates are toluene diisocyanate and diphenylmethane diisocyanate.  Suitable diamines are benzidine, 3:31-dichlorobenzidine, 3:31 - dichlorodiphenylmethane diamine, diphenylmethane diamine, o,o1-dinitrobenzidine, 2-methylpiperazine, hexamethylene diamine, and o-toluidine.  Suitable solvents include acetone, MEK, methylene dichloride, ethylene dichloride, methyl acetate, ethyl acetate, ethylene glycol methyl- or ethyl-ether acetates, DMSO, DMF, DMA, propylene carbonate and THF. The prepolymer and the diamine may be mixed by simultaneous spraying on to a surface, with the prepolymer at 5-100 DEG  C.  Pigments may be added to the diamine solution.  In Examples prepolymers are prepared from toluene diiso cyanate and various polypropylene or polyethylene glycols, and/or propoxylated- or ethoxylated- and propoxylated-trimethylolpropane or -glycerol or -pentaerythritol or -ethylenediamine, or, in part, trimethylolpropane.  These are sprayed on to surfaces simultaneously with solutions in acetate and/or ketone solvents of p,p1-diamino-diphenylmethane or m-phenylene diamine, or solutions of each of the above listed suitable diamines in suitable solvents.ALSO:Surfaces, e.g. roofing, floors, concrete walls and terraces, may be coated with a polyurethane by simultaneously spraying thereon a liquid polyurethane prepolymer and a solution of a diamine, (Ex 6).  The prepolymer has a viscosity of 4,000-20,000 centipoises at 25 DEG C and is prepared by reacting a polyether polyol with a polyisocyanate in proportions providing a ratio of NCO:OH groups of 1.5-3.0:1.  The final polyurethane has ratios of NCO:(OH + NH2)=0.95-1.6:1 and NH2:OH>0.5:1, calculated on the basis of the polyol, polyisocyanate and diamine starting materials.  A wooden board, metal plate, foamed sheet, e.g. expanded polyurethane, felt, leather or fabric may be coated with the polyurethane by transfer from a siliconized support which may have a grained surface, to produce for example a footwear sole, carpet for the automobile industry, decorative wall or floor coverings.
