Filed: 1975-09-24
Abstract: 1528584 Duplex D.C. data transmission MOTOROLA Inc 24 Sept 1975 [15 Oct 1974] 39142/75 Heading H4P A digital duplex synchronous or asynchronous system comprises at least two transmitting and receiving stations working over a single path, outgoing signals being combined with incoming signals to form a 3-level signal, e.g. by transmitting the signals as current signals and the outgoing signals being removed at the local receiver by combining the 3-level signal with a (voltage) signal derived from the outgoing signal. In Fig. 4 the outgoing digital signals are converted to constant current signals by switch S 1 (driven by a level shifter stage Q 1) so that incoming and outgoing signals combine across R L  to form a 3-level voltage signal. This is combined in DA with the outgoing signal level shifted in switch S2 in such a manner that the local signals are removed before passing to the receiver connected to the output of DA. A number of stations may be coupled to the single path (see Fig. 5, not shown) and coding arrangements may allow particular pairs of stations to work to each other while excluding others.

In an electrostatic printer having a wire matrix printing head and in which the surface of a record medium 6 is charged by the potential between printing electrodes 1 and counterelectrode 5, the printing electrodes 1 are connected through two dipoles 7, 7<SP>1</SP> (which may be replaced by resistances or capacitors) to respective potential switches 3, 4 so that when both potential switches are closed 3-P1 and 4-P1 the effective potential exceeds the threshold value for initiating a gas discharge to produce a record mark on the record medium, whereas, when only one of the switches 3 or 4 is connected the potential does not attain the threshold value and constitutes a bias value. A third dipole, an electrical resistor 9, may be connected to the printing electrodes and is maintained at a fixed potential.

[Also in Division F4] A burner, Fig. 1 (not shown) for producing a flow of highly ionized gases from the combustion of, e.g. gaseous or solid fuel, comprises an annular electrode 10 an a coaxial central electrode 14 between an electrical arc is continuously maintained, and a conduit 16 for delivering a fuel-oxidant mixture to the region adjacent the centre of the annular electrode 10. The annular electrode 10 is formed from a hollow ring of copper provided with inlet and outlet ports 11, 12 for cooling fluid and a tubular shield 15 surrounds the co-axial electrode 14 and is supplied with nitrogen, argon or other inert gases. The central electrode 14 may be made from tungsten, thoriated tungsten or graphite. In an alternative arrangement the tubular shield 15 is removed and the inert gas is delivered through the conduit 16, the fuel-oxidant mixture being then delivered through a plurality of nozzles disposed on the downstream side of the annular electrode 10 or alternatively through a plurality of ports in a combustion chamber into which the burner projects. In another construction, Fig. 6 (not shown) the mixture flows through a porous or perforated inner wall 28 to the region downstream of the electrode 10. The fuel and oxidant may be delivered separately one through nozzles disposed dowstream of the annular electrode 10 and the other through the conduit 16. The central electrode 14 may be replaced by a bed of tungsten or graphite chips supported on a porous diagram which extends across the shielding tube 15. Various forms of apparatus incorporating the burner are described in which the heat transfer to a body is increased or decreased by applying a positive or negative potential to the body so that the ionized gases are attracted to or repelled from the body. The apparatus of Fig. 6 is for producing substances by the recombination of dissociated molecules discharged by the burner and suddenly cooled by expansion and heat transfer with a cooling liquid. The sudden cooling may also be effected by quenching in water or other liquid.

In the illustrated embodiement, T 2  collector is high only if C and D are low so that T 2  is not turned on, and if A and B are high to prevent conduction through R, D 1  and the diodes D A , D B . Thus D A , D B  form an AND gate and D C , D D  an OR gate, whereby T 2  collector output S 2  = A.B.C.D, and this is inverted by T 1 . The Zener Z 2  prevents T 2  from conducting during this condition of A, B high and C, D low, because the base current of T 1  flowing through Z 1  and R causes a voltage across R sufficient to render Z 2  non-conductive.

Title: Process for producing water-insoluble azo-dyestuffs on vegetable fibres
Filed: 1958-12-22
Abstract: Azoic dyeings are produced on vegetable fibres by treating the fibres at a long goods-to-liquor ratio in a bath containing a coupling component and a diazoamino or tetrazoamino compound free from solubilising groups and developing the azo dyestuff in an acid bath. The dyebath preferably contains an alkali and a neutral salt and is applied at 30 DEG -60 DEG C.  Development may be effected by subsequently adding to the dyebath a compound of acid reaction, e.g. acetic, sulphuric, formic or oxalic acid or monosodium phosphate, or by treating the impregnated fibres in a separate bath with such a compound.  Development is preferably effected at a higher temperature.  Suitable diazoamino compounds are those formed from diazotised aromatic amines and diethylamine, methylethanolamine, diethanolamine, dicyclohexylamine or pyrrolidine and numerous examples are given. Suitable coupling components are the arylides of 2 : 3-hydroxynaphthoic acid, 2-hydroxy-anthracene-3-carboxylic acid or of 5-hydroxy-1 : 2 : 11 : 21-benzocarbazole-4-carboxylic acid, and acylacetylamino compounds of the benzene and diphenyl series.
