Title: Aircraft with folding wings
IPC: B64C3/56
Filed: 1947-04-29
Abstract: 627,121. Folding wings for aeroplanes. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU NORD. April 29, 1947, No. 11493. Convention date, Nov. 14, 1946. [Class 4] In an aircraft with folding wings, the movable portions 5 are connected to the fixed portions 4 by hinges whose axes X-X<SP>1</SP> are inclined and located in the longitudinal plane of the main spars 6, 8 of the wings. In the form shown, the hinge axes converge downwardly, the wing portion in front of each hinge being of stepped shape DEFG in plan, while the upper surface of the fixed wing portion 4 to the rear of the hinge is formed with a recess 9 to allow the passage of the lower edge 10 of the rear portion of the movable wing portion 5 during folding and unfolding. The undersurface of the fixed portion is formed with a horizontal extension 11 for supporting the wing portion 5, while the latter carries a flap 12 covering the recess 9 when the wing is extended. The wings may be operated by hydraulic or electric jacks 14, and remotely controlled locking devices 17, 18 may be employed for securing the wings in their extended position.

Title: Method of and device for producing coloured pictures
IPC: B44C3/12
Filed: 1933-01-17
Abstract: 400,807. Pictures; toys. WALBINGER, E., 35, Heidelbergerstrasse, Darmstadt, Germany. Jan. 17, 1933, No. 1518. Convention date, Jan. 19, 1932. [Classes 11 and 132 (iii).] Coloured pictures are produced by threading strips of coloured sheet material through pairs of slots formed in a baseplate, the slots and strips being so formed that the different areas of the picture to be produced are bounded by the slots and by the edges of the strips. The plate a is formed with pairs of slots b .. f to represent a pine-tree, each pair forming the two opposite sides of the contours of the portion of the picture included therebetween; the strip p is first applied, and subsequently the strips o, n, m, i, in overlapping relation, the lower edges l being toothed to represent the ends of the branches while the upper edges are straight. The strips may be variously coloured and additional effects may be produced by providing openings r through which shows an underneath strip, which is threaded through the slots with the strip n. Alternatively, additional slots s may be formed in the plate a with corresponding slots in the strip o, so that a strip t may be threaded through. The slots may be adapted to hold the material better by depressing the portion of the plate a on which are to be arranged the coloured strips, and one edge of the slot may be displaced relatively to the other. The strip material may be sold in sheet form divided into strips but united by one or both the marginal edges.

Abstract: 784,971. Gearing for stopping machinery; clutches. COLLINS RADIO CO. Jan. 24, 1956. No. 2364/56. Class 80 (2). Apparatus for positioning a shaft comprises electrical relay means to control a clutch locking and unlocking a toothed stopwheel. A shaft 13 supported in plates 10, 12, carries a clutch member 19 slidably keyed to the shaft and having a projection 23 engageable with the teeth of a stop-wheel 18 rigid with the plate 10. The complementary clutch member 28 is rotationally free on the shaft but is secured against axial movement and has gear teeth formed on its periphery. The clutch members are surrounded by an electromagnet 48 which, when energized, engages the clutch against the spring 34 and releases the projection 23 from the stop-wheel. A rod 42 passing through the plate 10 is contacted by the clutch member 19 on disengagement to break a switch 44 mounted on plate 10 and de-energize a motor 38 driving the clutch member 28 through gears 36, 37. To move the rotor 16 of a condenser 14 to a desired position, the knob 62 is turned to the selected number, a wiper 58 of a selector switch 59 is mechanically turned through a shaft 61 to earth the contact 3, and through the disc 52 of a seeker switch and contact 51 to energize the clutch coil 48 and motor 38. The shaft 13 is rotated by the motor and clutch until the gap 56 in the disc 52 of the seeker switch on the shaft is adjacent the contact connected to earth, the clutch circuit is thus broken, the member 19 moves to engage the projection 23 with the appropriate tooth of the stop-wheel, trips the switch 44 and de-energizes the motor 38.
