Patent GB-593199-A (GB)
Title: Aircraft instrument
IPC: B64D43/00
Filed: 1945-03-31
Abstract: 593,199. Indicating apparatus. SQUARE D CO. March 31, 1945, No. 8140. Convention date, April 1, 1944. [Class 106 (iv)] [Also in Groups XX and XXXVIII] An instrument giving both air speed and angle of attack has two relatively movable concentric dials and a movable pointer 29 co-operating therewith, the outer stationary dial 52 being for airspeed and an inner rotatable dial 51 for angle of attack. The airspeed indication is derived from the movement of a diaphragm capsule 9 connected to a pilot tube and is transmitted by links 14, 15 to a shaft 16 and a gear quadrant 22 having a counterbalance weight 23, and driving a gear 31 connected to the pointer 29. The angle of attack indication is derived from the movement of a vane 65 relative to the housing 64. This movement displaces the rotor of a selsyn motor within the casing causing a corresponding displacement of the rotor 35 of the receiver 33. This displacement is transmitted by a chain of gears 36-41 to a cage 42. A gear 45 is also connected by gears 46, 48 to the inner rotatable dial 51, whereby the movement of the vane 65 is transmitted to indicate the angle of attack. A change in airspeed produces a movement of the needle 29 and a corresponding movement of the dial 51 through the gears 21; 47, 45, 46. 48 so that the angle of attack indication remains the same. This latter indication is corrected for the effect of flaps 63 or slots on the wing by an arrangement shown diagrammatically in Figs. 1, 1a. Displacement of the flap is transmitted through a cam mechanism 61, which evaluates the true effect of the flap angle on the angle of attack, and gears 56, 55, 53 to the outside 34 of the selsyn receiver 33. Another method of making this correction uses a rotatable transformer in the selsyn circuit which transformer is turned by the flap through the cam mechanism.

Abstract: 578,457. Broad band antennae. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1944, No. 8203. Convention date, May 15, 1943. [Class 40 (v)] Abroad band dipole antenna for aircraft comprises a conical element 60 adapted to be mounted on the airframe 2 and a flat or slightly curved disc-shaped element 62 arranged adjacent the apex of the conical element. The antenna is fed by a concentric-conductor transmission line, the outer conductor 14 of which is connected to the apex of the cone 60 whilst the inner .conductor 12 is connected to the disc 62 which it may rigidly support. The complete antenna may be covered by a spherical shield 64 of non-conducting material to reduce wind resistance, and the disc-shaped element may be mounted inside or outside the spherical shield, or in an aperture therein, the whole having the appearance of a spherical " blister " on the airframe. The disc-shaped element may take the form of a layer of metal deposited on the non-conducting shield by sputtering. If the part 2 of the airframe is of metal, it acts as an extension of the conical element 60 to lower the band-width, and, if not of conducting material, the same effect may be produced by placing a conducting surface over this part of the airframe.
