Patent GB-351905-A (GB)
Filed: 1929-12-18
Abstract: N-Aryl-cyclohexylamines.-An N-nitroaryl-cyclohexylamine is acylated and the product treated with a reducing agent to yield an N-acylcyclohexylamino-arylamine.  These bodies can be diazotized and coupled with azo-components or the acyl residue can be split off by saponification; they are stable to oxidizing agents.  In examples N-4-nitrobenzene-cyclohexylamine is treated with acetic anhydride and the acetyl derivative reduced in acid solution with iron turnings; it yields a diazo body coupling with azo-components.  In similar manner N-4-nitro-2-sulphobenzene-cyclohexylamine can be converted to N-4-amino-2-sulphobenzene - acetyl-cyclohexylamine the diazo solution of which couples with azo components, and N - 2 - amino - 4 - sulphobenzene - acetylcyclohexylamine is also prepared in the same way.  Sodium sulphide may alternatively be used as reducing agent.

Title: Switching devices for superconducting power cables
IPC: H01F6/00
Filed: 1966-08-31
Abstract: 1,127,658. Arc-rupturing. SIEMENSSCHUCKERTWERKE A.G. 31 Aug., 1966 [31 Aug., 1965], No. 38954/66. Heading H1N. [Also in Division H2] A switching arrangement for a superconducting power cable comprises a superconducting circuit-breaker 4 and a superconducting member 3 in series with the cable and a power circuit-breaker 5 disposed externally of the thermal insulation of the superconducting system and connected in parallel with the member 3 or, preferably, in parallel with the series combination of the circuit, breaker 4 and member 3. In the arrangement shown to interrupt the cable circuit 1, a magnetic or heat pulse is applied by a control circuit 10 to the member 3 causing it to change to a high resistance normally-conducting state. The superconducting circuit-breaker 4 is then opened to interrupt the residual current through the member 3. The entire current is now carried by the power circuit-breaker 5 which is opened to interrupt the cable circuit. By using such an arrangement, arcing only occurs at the contacts of the circuit-breaker 5 so that the energy released by the arc is dispersed outside the thermal insulation of the superconducting system. The operation of the circuit-breakers 4 and 5 may be made dependent on the voltage arising at the member 3 when it assumes its high resistance state and the operation of the switching arrangement may be controlled by an overcurrent relay. A spark gap 9 may be connected across the circuit-breaker 4.
