The two circuits are coupled by a trigger circuit constituted by a resistor 126 and a feedback circuit consisted by a resistor 122 such that when the switch 118 closes the switch 114 is triggered closed and when said switch 114 closes said switch 118 is triggered to revert back to its normally open state. A control actuator 110 for the contacts 110-1 and a flame-sensing actuator 112 for the contacts 112-1 and 112-2 and controlled by the circuit 100 are also included in the two circuits. Contacts 108-2, 110-1 and 112-1 are normally open and contacts 108-1 and 112-2 are normally closed. A request for operation is signalled by the thermostat 24 and a blower 28 is operated and a switch 36, responsive to air flow, closes. After a delay switch 106 has closed, the actuator 110 closes switch 110-1 to initiate ignition of the pilot fuel. Also the switch 118 is closed and consequentally as explained above, switch 114 is triggered on and latches on, and switch 118 reverts back to its previous state. If a flame is established before the actuator 108 operates switch 108-1 (the delay is caused by a heating circuit which takes 5-30 seconds before reaching a desired operating temperature) actuator 112 switches over contacts 112-1 and 112-2 to ignite the main fuel. At the same time a signal is applied to switch 116 to break the circuit to the actuator 108. Should the fuel fail to ignite, or subsequently goes out, the actuator 108 operates to lock-out the burner control devices and energize an alarm 26. If a flame is present initially switch 120 will be on. This will prevent switch 114 from being switched on and will enable actuator 108 to be energized through switch 118, to operate the lock-out arrangements.

The carbon nucleophile is preferably a magnesium Grignard reagent, but may also be, for example, an organolithium compound, a cadmium, zinc or thallium Grignard reagent or a metal salt of a reagent containing a reactive methylene group. Other groups present in the molecule may also react with the nucleophile, e.g. a 3-acyloxy group is converted to a 3-hydroxy group (it may subsequently be re-acylated). The products may be converted to 16-R-20-keto-pregn-16- enes by several routes. Thus compounds (VII) wherein Y is other than -O.CO- may be acylated to form pseudo-sapogenins, e.g. 3#- acetoxy - 9α,11α - epoxy - 16α - methyl - 26 - nor- 26 - (N - acetyl) - carbdmido - furost - 20(22)- ene, these cleaned oxidatively to form 16- acyloxy - pregnan - 20 - ones and these hydro. lysed with dehydration; or compounds (III) may be subjected to the last two of these stages, or compounds (VII) wherein Y is -O.CO- or compounds (VIII) may be treated with a base to give the required products directly.  Methyl#<SP>9(11)</SP>-hecogenoate acetate is prepared by the action of diazomethane on #<SP>9(11)</SP>-hecogenoic acid acetate, in turn prepared by CrO 3  oxidation of #<SP>9</SP>(<SP>11</SP>)-hecogenin acetate. Methyl 9α,11α-epoxy tigogenoate acetate and 9α,11α-epoxy-tigogenoic acid acetate are prepared similarly, the starting 9α,11α-epoxy-tigogenin acetate being prepared by epoxidation of #<SP>9(11)</SP>-tigogenin acetate using monoperphthalic acid. 9α,11α-epoxy-tigogenamide acetate is prepared from the free acid using ethyl chloroformate and liquid ammonia. Methyl 9α-fluoro-11-keto-tigogenoate acetate is prepared by oxidation and esterification of 9α -fluoro - 11# - hydroxy - tigogenin acetate, in turn prepared (together with 11-keto-tigogenin acetate) from 9#,11#-epozy-tigoyenin acetate, which is itself prepared from #<SP>9(11)</SP>-tigogenin acetate by formation of the bromohydrin followed by dehydrobromination.
