Air for combustion drawn through an intake 6 by a fan 7 is pre-heated by passing it through the cold passages 8 of a heat exchanger, the hot gasses 10 of which receive the exhaust from the last combustion chamber 2. Ducting 9 connects the heat exchanger passages 8 with the inlet to the first combustion chamber 1. The exhaust gases finally pass to a waste heat chimney 11. Steam from the boiler 14 passes through superheater 12 to the H.P. steam turbine 16 from which the exhaust is passed through a steam re-heater 13 in combustion chamber 1 and thence to the L.P. steam turbine 17 which is provided with a condenser 18. Condensate from the condenser 18 is forced by a pump 19 through bled steam heaters 20 and 21 and then by pumps 22, 23 through an economizer 15, disposed in combustion chamber 2, to boiler 14. Fig. 2 shows the application of the invention to a mercury and steam plant operating in a binary cycle. A mercury turbine 24 exhausts to a steam boiler 25 and the condensed mercury passes through a feed pump 22 to an economizer 27 and mercury boiler 28 disposed in the second combustion chamber 2.

[Also in Group XXXV] In a motor control system for a delivering conveyer, a first signal controls the rate of transfer of material to the conveyer from a supply station situated near to the delivery station of the conveyer and a second signal controls the rate of transfer to the conveyer from all the supply stations along the conveyer. As shown, motors MT1-MT3 drive turntables feeding a constant-speed conveyer. The motor fields F1-F3 are energized from constant potential lines L3, L4 and the armatures from a magnetic amplifier MST. The weight of material on the conveyer is detected by a device W. A first signal from the device W energizes a control winding CL3 of a magnetic amplifier MA2 to vary the energization of the field winding F1 of the motor MT1 so as to correct short term variation in the weight of material delivered by the conveyer by varying the transfer rate of the turntable driven by the motor MT1, situated near to the delivery end of the conveyer. A second signal from the device W energizes a control winding CL2 of a magnetic amplifier MA1, the output of which supplies a motor EM driving through a reduction gear SDG an induction regulator 1R controlling the energization of a control winding CL4 of the magnetic amplifier MST so as to vary the armature voltages of motors MT1-MT3 and correct long-term variation in the weight of material delivered by the conveyer by controlling the transfer rates of all the turntables. The transfer rate of all the turntables is set by a potentiometer PT1 supplying a control winding CL1 of the magnetic amplifier MST. The transfer rates of the turntables driven by motors MT2, MT3 are adjusted by rheostats VR2, VR3. Specifications 822,743, 824,788, 867,865 and 873,899 are referred to.

Title: Method of preparing n,n-disubstituted formamidines
Filed: 1955-11-04
Abstract: Poly-N:N1-disubstituted formamidines are made by reacting a poly primary amine with 1:3:5-triazine.  The reaction may be effected by mixing the reactants at room temperature and heating if necessary. Ammonia is evolved.  An inert solvent or diluent such as heptane, petroleum ether, benzene, toluene, xylene, chlorobenzene, trichloroethylene, tetrachloroethylene, chloroform or carbon tetrachloride may be used.  Polyamines mentioned are 1:4-diamino-butane, 1:4-diamino-cyclohexane, and p-phenylene diamine. The chain length of the polymer is controlled by adding a small amount of a monoamine; cross linking is effected by adding polyamines containing greater numbers of amino groups.ALSO:N : N1-disubstituted formamidines of the formula: R-NH-CH=N-R where R is a substituted or unsubstituted hydrocarbon radical, the substituents being non-functional in the reaction, or a heterocyclic radical in which the hetero-atoms do not interfere with the reaction and any substituents of which are non-functional in the reaction, are made by reacting a primary amine of the formula R-NH2 with 1 : 3 : 5-triazine.  The reaction occurs on mixing the reactants at room temperature or on heating, and ammonia is evolved.  Inert solvents or diluents may be used, such as heptane, petroleum ether, benzene, toluene, xylene, chlorbenzene, trichloroethylene, tetrachloroethylene, chloroform and carbon tetrachloride.  Primary amines which are mentioned and which may contain substituents such as halogen atoms, or nitro, carbonyl, amido, carboxylic ester, secondary and tertiary amino, ether, and thioether groups are methyl-, ethyl-, isopropyl-, sec-butyl-, n-butyl-, n-heptyl-, n-dodecyl-, benzyl-, cyclohexyl-, and a - and b -naphthyl-amines, aniline, the toluidines and xylidines, 2-amino-pyridine, amido-thiazole, o-chloro aniline, amino-acetone, amino-acetophenone, ethyl alanine, p-nitraniline, ethoxyethyl amine, m-anisidine, amino-ethyl 2 : 4 : 5 - trichlorophenoxy - acetate, aminoethylthioethane, p - amino - acetanilide, 1 - amino - 4 - ethylamino - butane, 1 - amino - 4 - (ethylmethyl) - amino - butane, and amino-ethyl-methyl-aniline.
