An apparatus for inter-connecting power systems each including generators and loads comprises a reactor device connected between the systems and means for generating a first compensating voltage which compensates for a voltage drop developed across the reactor device. A second voltage displaced at 90 degrees to the first may also be generated. In the embodiments described the reactors comprise a transformer having a series winding, e.g. 304a, for each phase into which is injected a quadrature first voltage from a winding 305a developed by the voltage difference between windings 309a, 309c of another transformer 306 representative of the voltage difference between the taps on windings 304b, 304c. The taps may divide the winding or may be at one end. A directional in-phase second voltage may be added to the quadrature voltage which in an alternative embodiment, Figs. 7a, 7b (not shown), is derived from taps on tertiary windings (311a-311c) with additional tapped tertiary windings (309a-309c) providing the quadrature voltages. Such taps may be arranged for off-load tap changing and a current limiting reactor (321) may be included. In a further refinement, Fig. 7a (not shown), load current limiting reactors (322a-322c) are connectible across windings (305a-305c). The relevant potentials, phase differences, current, frequency, and frequency change may be sensed in a circuit, Fig. 8 (not shown), to control the operation of the arrangement also to detect fault conditions when reactors 325 will be inserted.

Abstract: 1,259,461. Aircraft refuelling apparatus; floating tanks. FLIGHT REFUELLING Ltd. 21 July, 1969 [22 July, 1968], No. 34956/68. Headings B7A and B7G. [Also in Divisions E2 and F2] Refuelling apparatus for a hovering aircraft comprises a coupling member 12, Fig. 3, connected by a hose 15 to a fuel storage container 1, Fig. 2, within a non-airborne member such as a buoy, a retractable coupling member or nozzle sinker 21 which can be lowered from the aircraft to engage the hose coupling 12 and raised again to be engaged with an airborne fuel hose coupling means 30, Fig. 5, and control means responsive to electrical control signals for effecting connection of the retractable coupling member and the non-airborne fuel hose coupling. Reception of a radio signal (tone A) by a lowpower receiver in the buoy causes a power plant therein to be switched on and an encircling band 19 to be actuated to move toggle levers 16 out of the path of the nozzle sinker 21, which has been unlocked from the aircraft coupling 30, Fig. 5, and lowered into position as shown in Fig. 3. Then a second signal (tone B) releases the band 19, allowing the levers 16 to be moved by jacks 17 to grip the nozzle sinker by engagement in groove 22. The nozzle sinker and hose coupling are then raised up and locked to the aircraft coupling, whereupon the aircraft fuel tanks are connected to a three-way valve 6, Fig. 2, of the buoy by a fuel-tight passage. Transmission of a third tone C causes a fuel pump 2 to be rendered operative and the valve 6 toconnect the pump to the hose reel outlet, thereby allowing fuel to be transferred. Tone C is re-transmitted on completion of the fuel transfer, causing cessation of pumping and connection by valve 6 of the hose with the fuel containing buoy 1, so that fuel can drain from the hose to the container with the aid of air entering the hose via a valve 34, Fig. 5, in the aircraft coupling 30. The nozzle sinker 21 is then unlocked from the aircraft coupling and lowered back to the buoy, the hose reel reeling in the hose until the hose coupling is again located in the throat of the divergent cone 10 of the buoy. Retransmission of tone B allows the nozzle sinker 21 to be disengaged from the hose coupling 12 and to be hoisted back into the aircraft. The buoy power plant may then be switched off by retransmission of tone A or by a time switch incorporated in the buoy.

An induction motor which drives a fan has a main winding 3 and a tapped auxiliary winding 4 associated with a selector contact 12. Relays 10, 11, 13, are changed-over when a guard for the fan-blades is touched whereby the motor is stopped by direct braking current derived from a rectifier 6. After a period, a relay 14 is actuated to engage contact G, and the motor is disconnected from the supply circuit. Following a further interval the relays 10, 11, 13, are returned to their initial positions, the motor receiving the full source voltage through the relays 13, 14. This ensures that the motor re-starts although the selector contact 12 may have been left in its low-voltage setting c, c<SP>1</SP>. The relay 14 engages contact H after another delay period so that the motor then operates at a speed determined by the position of the contact 12. A coil for operating the relays 10, 11, 13 is associated with a monostable multi-vibrator comprising a pair of transistors which change their state upon reception of a braking signal. When a capacitor has discharged to a predetermined voltage-level, a further transistor becomes non-conductive to de-energize the coil of the relay 14. When the braking signal is removed the first relay coil is de-energized but the second coil is not energized until a delay period has elapsed, Fig. 4 (not shown).

In the arrangement shown, the hot oxygen-depleted air stream from the oxidizing column (1 or 3 alternately) is utilized (via lines 13 or 31) in heat exchangers 11 and 21 to preheat the air and fuel for the respective reactions going on in the two columns. In another arrangement described (Fig. 2) each column comprises two cobalt beds and two coke beds stacked one above the other and so that each coke bed is above a cobalt bed. In the oxidizing column the oxidizing air stream burns the coke to CO and CO 2  and at the same time oxidizes the cobalt oxide to its higher oxide (Co 3 O 4 ). The gaseous products from this column are burned in a combustor (55 or 113) the combustion products from which are utilized in a heat exchanger (59 or 117) to heat the process fluid. In the reducing column heat is generated by the reaction of CO (initially from a tank 81 or 33 but subsequently from the uppermost coke bed) with the lowest of the metal oxide beds (19 or 99). The reaction products flowing upwardly, gasify the first coke bed and are heated further in exothermic reaction with the uppermost oxide bed. The stream from this reaction gasifies the uppermost coke bed in the column and some of the resulting CO is recycled to the foot of the column (i.e. to the lowermost oxide bed), the remainder being passed into the combustor (113 or 55) from which the combustion products flow to the heat exchanger (117 or 59) which supplies heat to the process fluid.
