Title: Aircraft ejection seats
Inventor: AXENBORG CARL EVERT
IPC: F02K9/84
Filed: 1968-07-08
Abstract: 1,240,340. Aircraft Ejection seat. SAAB SCANIA A.B. 8 July, 1968 [10 July, 1967], No. 32449/68. Heading B7G. In an aircraft ejection seat, the thrust line of a rocket motor is moved automatically to accommodate changes in the position of the centre of gravity of an airman/seat combination and/or two different ranges of aircraft speed. Thrust line 10 may be altered by rotating a rocket 8 using a double-armed lever 11 rotatably suspended from a frame part 1 on a fulcrum pin 12, the lower arm 13 of which engages with a shoulder 14 on the rocket easing 19 whilst the upper arm 15 carries a curved slot 16 whose length corresponds to the maximum distance the seat part 3 may be moved in guides 5 by a jack 6, the lever 11 being actuated via a guide pin 17 by the displacement of the seat 3 relative to the frame part 1. The thrust line may be further modified for ejection at high flight speeds by apparatus comprising speed compensator 50, an arm 48 and pressure differential indicator 43. Upon attainment of a minimum flight speed a pressure differential develops across bellows 43a, to produce sufficient axial movement of pin 47 so that upon ejection of the seat, pin 47 engages with the arm 48 whereupon the arm 48 moves link guide 51 into engagement with latch 56 so moving the pin 57 mounted on roller-guided runner 52 upwards. The movement of the pin 57 may be transmitted via lever 11 to rocket 8 thereby appropriately modifying its thrust line to pass behind the seat centre of gravity. In alternative embodiments, changes in the seat centre of gravity may be relayed to the rocket by a threaded spindle co-operating with a toothed segment or by a steel band looped round and attached to the seat and rocket casing. In a further embodiment, the thrust direction of a non-rotatable rocket may be varied with changes in the seat centre of gravity by means of a movable curved exhaust-gas deflecting screen attached to the seat 3 by linkage.

Title: Improvements in or relating to burner installations
IPC: F23N5/08
Filed: 1963-08-22
Abstract: 1,058,223. Control and safety devices for burners. COMPAGNIE ELECTRO-MECANIQUE. Aug. 22, 1963 [Oct. 29, 1962], No. 33337/63. Heading F4T. A control and safety device for oil or gas burners comprises a photoresistive cell X in parallel with a relay winding RF which, in the absence of a flame, closes a contact 1RF to energize the starting winding 12 of a singlephase motor M driving a fuel pump and an air fan, and to energize the primary winding of a spark ignition transformer TA, the device being energized through a thermal circuit-breaker D initially by a space thermostat TH. If the burner ignites, the cell X short-circuits the relay winding RF and de-energizes the motor starting winding 12 and the transformer TA. If the burner does not ignite, the relay winding RF remains energized and the current flowing in both the windings of the motor M, is sufficient to trip the thermal circuit breaker D after a finite delay time. If the dark resistance of the cell X falls, the relay winding and hence the starting winding 12 do not become energized, but the current flowing in the stationary motor is sufficient to trip the circuit breaker D. An electromagnetic valve may be connected in parallel with the motor or members (not shown) to delay starting of the motor, or delay disconnection of the transformer.
