Substituted tri-aminoborazoles are made by treating a substituted tris(amino) borane with an amine salt of sulphuric, hydrochloric, hydrobromic or trifluoroacetic acid, the substituted tris(amino) borane being a primary or secondary tris(alkylamino) borane or tris (alkenylamino) borane in which the alkyl or alkenyl groups have from 1 to 6 carbon atoms, a primary or secondary tris(phenylamino) borane, a primary or secondary tris(thiophenylamino) borane, a primary or secondary tris(pyridylamino) borane or tris-pyrrolo-borane; the amine salt being a salt of a primary, secondary or tertiary alkylamine or alkenylamine in which the alkyl or alkenyl groups have from 1 to 6 carbon atoms, or of a primary, secondary or tertiary phenylamine, thiophenylamine or pyridylamine, or of pyridine or pyrrole, and at least one of the two starting compounds first specified being derived from a primary amine. When primary or secondary aminoboranes are used with primary or secondary amine salts having on their nitrogen atoms groups different from the groups on the nitrogen atoms of the aminoboranes, the borazole product includes ring substituents from both reactants. When a primary aminoborane is used with a tertiary amine salt the ring substituents of the borazole are all derived from the aminoborane. Examples describe the preparation of (1) B-tris(isopropylamino)-N-triisopropylborazole from isopropylamine hydrochloride and tris(isopropylamino) borane; (2) triisopropyl-trimethyl-B-triaminoborazole from tris(isopropylamino) borane and methylamine hydrochloride; and (3) B-tris(anilino)-N-triphenylborazole from tris(anilino) borane and trimethylamine sulphate. The borazoles are useful additives for motor spirit, Diesel oil and jet fuel.

Abstract: 540,172. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd., and WILSON, W. March 4, 1940, No. 4029. [Class 38 (v)] In a busbar-protective system of the kind in which the input from circuits 2 ... 4 is compared with the output at circuits 5 ... 7 by means of relays having operating windings connected across current-transformer groups in the circuits so as to carry the difference-current, restraint against operation by spill-over currents due to current-transformer differences on heavy through-faults, is provided by means of further windings carrying the total through-current. In the arrangement shown, each phase is protected separately by relays having operating windings 20 ... 22, restraining windings 14 ... 16, and parallel-connected trip contacts (not shown), whereby difference currents due to both earth and interphase faults affect the relay of the affected phase or phases. Where busbars are segregated and metal clad, so that every fault is a fault to earth, all the incoming transformers may be balanced against all the outgoing ones in a single relay. A combination of the above arrangements is also described, the additional relay contacts being connected in series or in parallel with the contacts of the phase relays according as it is desired to obtain a safeguard against unintentional tripping (and earth-fault operation only) or an increased degree of protection against both kinds of fault. In the latter case, an earth fault causes operation of the additional and one phase relay, and an interphase fault causes operation of two phase relays, and as the contacts are in parallel, failure of a relay to operate is unimportant.
