Abstract: 674,994. Cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and LORCH, H. R. Oct. 13, 1950 [Oct. 14, 1949], No. 26390/49. Class 36. [Also in Group XXII] An insulated electric conductor comprises one or more wires embedded in powdered talc and enclosed in an aluminium sheath which has been drawn down to compress the powder. The aluminium sheath may be extruded around, but not in contact with, the wires, the space within the sheath being filled with dry talc powder as the sheath is formed, or the cable may be made by applying the powder to the wires in the form of a paste which is then dried and around which the aluminium sheath is extruded. The aluminium sheath is formed in an extrusion press having a hollow ram 1 within which is a hollow mandrel 5 through which the wire 11 is passed. If the talc is to be applied as a powder it is fed from a hopper 7 supported above the mandrel 5, and is forced into the extruded aluminium sheath by a damper 9. The covered wire then passes through a reducing die 12 which draws down aluminium sheath and compresses the talc. In the alternative method the talc is in the form of a paste and is applied to the wire by extrusion. The wire then passes through a drying oven. before reaching the aluminium press, from which the hopper and ram are omitted.

[Class 4] Operation of aeroplane wing flaps of the split trailing edge type is assisted by arranging one part of the flap to move to its operative position in opposite sense to the remainder. As applied to a low wing monoplane, Fig. 3, comprising a fuselage 1 with a substantially flat under surface 2, stub wings 3, 4 and outer folding planes 5, 6, the flaps are divided into five sections of which the two outer, 10A, 10B, are carried by hinged trailing edge parts 9, Fig. 5, of planes 5, 6 respectively, Fig. 5, two inner sections 10C, 10D carried by the stub wings and a section 10E carried by the fuselage. Sections 10A, 10B and 10C, 10D are rotatably carried by spindles 11, 12 respectively which are operatively interconnected by tongue-and-slot means, Fig. 7, designed to allow for the lack of axial alignment between the spindles and to permit automatic connection and disconnection thereof when parts 9 are turned upwardly to permit wing folding or are returned to normal position. Spindles 12 are connected by toothed sectors as shown in Fig. 4 to spindle 13 of flap section 10E which is normally nested against the underside of the fuselage but adapted to extend in alignment with the remaining sections when these are fully depressed. The dimensions of flap 10E are such as not completely to balance the other flaps aerodynamically at any position. Section 10E may be arranged to move through a larger angle in reaching its operative position than the remainder, i.e. the flap sections may be arranged to be in alignment when depressed to an angle of less than 90‹ to the wing chord. According to a modification the tongue and slot arrangement of Fig. 7 may be substituted by gear sectors such as 14, 15, Fig. 4, when it is desired to reverse the direction of movement between flaps on a fixed and on a folding part of the wing. The flaps are constituted by plywood or metal surfaces mounted on levers of girder section such as 18, Fig. 4. The levers may be sunk into the surface to which they are attached and a capping be provided on the fixed trailing edges so that the flaps are flush with the wing contour when inoperative.
