Title: Dehalogenation of chlorofluorocyclic compounds
Inventor: MUSGRAVE WILLIAM KENNETH RODGE
IPC: C07C17/23
Filed: 1961-05-08
Abstract: Highly fluorinated aromatic compounds are made by heating saturated or partially saturated, chlorofluorocyclic compounds in the presence of metallic iron, preferably at between 200 and 500 DEG C.  Suitable starting materials for the dehalogenation are chlorofluorocyclohexanes and chorofluorocyclohexenes or a mixture of chlorofluorocyclohexanes and hydrochlorofluorocyclohexanes. The chlorofluorocyclic starting materials may be made by the reaction of (1) chlorine trifluoride with hexachlorobenzene in the vapour phase or the liquid phase, (2) cobalt trifluoride with hexachlorobenzene in the vapour phase, (3) chlorine trifluoride with benzene in the vapour phase over a copper catalyst, or (4) antimony pentafluoride with hexachlorobenzene.  Detailed examples describe the preparation of series of chlorofluorocyclohexanes and their dehalogenation to highly fluorinated benzene compounds.

Title: Sequential switching device
IPC: H03K3/352
Filed: 1971-05-25
Abstract: 1368462 Protective arrangements D D BOWEN 17 Jan 1972 [27 Jan 1971 25 May 1971] 3335/71 and 16787/71 Heading H2K A sequential switching arrangement comprises a solid state oscillator circuit normally producing a series of pulses, means, e.g. contacts OT1, for applying an input signal to the circuit to prevent the circuit oscillating, means, e.g. a relay RA, for repeating the input signal, normally held operated by the pulses, and means indi eating the failure of a component when the oscillation ceases in the absence of an input signal. In the arrangement shown, remotely situated contacts OT1 are normally closed, a transistor T12 is "on" and a transistor T1 is rendered alternately conducting and non- conducting by an oscillator T4. The relay RA has a delayed release so that the intermittent short-circuiting by the transistors T1, T12 does not cause it to release. The pulses in the relay circuit acting through a capacitor C2 cause transistors T5, T6 to energize the warning lamps L2. When the contacts OT1 open, e.g. due to the opening of an associated circuit-breaker, the potential applied through Zener diodes ZN1, ZN2 from a potentiometer R8, R5, R6 to the base of the transistor T1 causes it to conduct continuously so short-circuiting the coil of the relay RA which opens contacts RA1 in a trip circuit, e.g. to open a further circuit-breaker. The relay also closes its contacts RA2 to cause a transistor T2 to conduct to place a further short circuit across the relay coil and to switch on a transistor T3 to switch off transistors T9, T10 to extinguish a lamp L1 to indicate the deenergizing of the relay RA. The closing of the contacts RA2 also connects the base of the transistor T5 to the positive supply conductor so that the transistors T5, T6 continue to conduct and the lamp L2 remains lit, but should the pulses cease when the contacts OT1 have not opened to cause the release of the relay, then the lamp L2 is extinguished to indicate the fault condition. Should the conductors of the cable leading to the contacts OT1 become short circuited, the short circuiting causes the potential at a point A to fall sufficiently to turn off transistors T7, T8 so extinguishing a lamp L3. Should the cable become open-circuited, then a transistor T11 is caused to switch off the transistor T12 to prevent the release of the relay RA.
