Title: Improvements in aeroplanes
IPC: B64C3/46
Filed: 1924-09-03
Abstract: 243,460. Ziemss, H. Sept. 3, 1924. Steering, balancing, and controlling altitude; planes, construction of.-The camber of an aerofoil, the ribs of which consist of a number of relatively-movable sections, is varied by pneumatic means associated with one of the rib sections. In the arrangement shown, the aerofoil framework comprises front and rear spars 1, 2, and ribs formed of front, central, and rear portions 5, 4, 6, and upper and lower booms 8, 9. The upper boom is formed in two parts, a fixed front part 8 extending to the rear spar 2, and a longitudially-movable rear part 8<a> the adjoining end of which is tongued and carries a pin 23, Fig. 6, sliding in a slot 22 in a strap 21 secured to the spar 2. The lower boom 9 is longitudinally movable in guides 19 fixed to the spars 1, 2. The forward rib section 5 comprises a nose piece 13 and arms 11, 12 both pivotally mounted at one end in a block 16 on the lower boom 9, and at their other ends pivoted respectively to the spar 1 and the upper boom 8. The central web section 4 is formed with a concave lower edge, between a flange 27, Fig. 2, on which, and the lower boom 9, is positioned a pneumatic tube 25 held in position by straps 28. The tubes 25 below each of the ribs are connected by pipes 26 communicating with a source of compressed air. The rear rib section 6 comprises a web portion 14 and a tail piece 15. When the machine is in flight, the pressure of the air on the under surface forces up the lower rib booms 9 and causes the front and rear portions 5, 6 to be projected downwards. In the extreme lower position a wing section is formed similar to the R.A.F. No. 6 except that the lower surface has a slight central indentation due to the rear spar 2 being slightly thicker than the depth of the central rib sections. By suitably regulating the air pressure in the tubes 25 the air pressure upon the wings may be made to vary automatically the wing camber to meet the varying conditions when the machine is climbing or flying horizontally. On the other hand the pilot, by suitably inflating the tubes 25, may adjust the camber in any desired manner. Other means may be employed in combination with or independently of the previously-described means, for moving the rear rib sections 6. This means comprises a pneumatic tube 29 extending longitudinally of the wing and secured in position near the upper surface between the rear spar 2 and a lath 30 fixed to the forward ends of the rear webs 14, so that when the tube 29 is inflated the rear wing section is moved downwards. Lateral control may by obtained by varying the relative camber of the wing on opposite sides.

A unitary transparency frame of plastics material includes a receiving slot 4, the two halves of the frame being adapted to be spread apart near the receiving slot to facilitate the insertion of a transparency. The transparency is locked in position by means of a deformation in at least one half of the frame. In the embodiment of Fig. 3 a limiting cam 6 or (6') is provided in each frame half 5 or (5') to register with a corresponding groove (7') or 7 in the other half. The two halves of the frame are spread apart by applying oppositely directed forces on the side edges of the frame adjacent the slot 4 in order to separate the cams 6, (6'). Each frame half 5, (5') may be provided with two bores adjacent the slot 4 so that the halves may be spread apart by mandrels passing through these bores to engage the inside surface of the opposing frame half. These bores are arranged in the halves 5 (5') so that the mandrels act as guide pins for the transparency. In the embodiment of Figs. 12 and 13 (not shown) the boundary (35) of the receiving pocket (36) is continued into the receiving slot (34) by means of webs (37), (38). When pressure is applied as shown in Fig. 13 the webs provide a lever action so that the receiving slot is widened. The frame may be provided with two receiving slots at opposite ends thereof. In a further embodiment the transparency is locked in position by means of central dead-ended holes adjacent the receiving slot to which are applied punches in order to weld the two halves together or merely to deform the frame.

Abstract: 639,040. Electric cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd., BRAZIER, L. G., and HARTSHORN, P. R. Aug. 11, 1948, No. 21158. [Class 36] An overhead power conductor 2 is surrounded by a conduc- , tive structure 1 of openwork or discontinuous form which is in electrical connection with the conductor, the outer edges of the structure, which are of small radius of curvature, defining an envelope that encloses and screens the conductor. The screen may be in the form of an open wire helix, Fig. 1, which may either hang directly on the conductor or be supported, as by conducting spokes, so as to be coaxial with the conductor. The pitch of the helix may be reversed at frequent intervals so that the screen may be sprung into position over the conductor. Alternatively, the helix may be made from a flat metal strip 5 or an L-shaped metal strip 6 applied edgewise, Fig. 3. The radius of curvature of the peripheral edge of the strip corresponds to that of the wire 1, Fig. 1. In a further modification, the screen may comprise a number of thin discs fitted on the conductor at frequent intervals and having rounded peripheral edges which may be continuous or broken up into small domes. Another type of screen comprises a cage of split wire rings connected together by a longitudinal spacing strip. A modified form may be made by bending a single length of wire 11 as shown in Fig. 6. In a further embodiment the screen consists of a series of open wire helices each consisting of a few turns of wire and having a varying diameter so that the ends of each section grip the conductor. In all the above examples the screens may be wholly of metal or may be formed of a non-conductive material such as thermoplastic, parts of which are metallised.
