Title: Aircraft parts, with sheet coverings
IPC: B64C3/26
Filed: 1945-07-10
Abstract: 609,311. Coverings for aircraft parts. ENGINEERING & RESEARCH CORPORATION. July 10, 1945, No'. 17598. Convention date, Feb. 16. [Class 4]. To prevent the formation of wrinkles and waves inclined to the direction of flight in the flexible covering (e.g. of sheet metal) of an aircraft surface, the covering is formed with corrugations extending in the direction of flight, which corrugations are continuous, i.e. run directly into one another as opposed to separate corrugations or ridges on an otherwise plain surface. The corrugations are of such small height (of the order of a tenth to a hundredth of an inch) and of such great pitch and height ratio (at least 5 : 1 and preferably more than 10: 1) that they do not appreciably increase the rigidity of the structure. In a wing structure, the ribs are preferably spaced apart by a multiple of the pitch of the corrugations to facilitate attachment of the covering and the depth of the corrugations decreases towards the leading and trailing edges.

Abstract: 1,068,093. Orientating crank-shafts; step by step conveyer. AJEM LABORATORIES Inc. April 30, 1964 [May 1, 1963], No. 18076/64. Headings B8A and B8S. A crank-shaft 4 is conveyed step by step along a walking beam and at a point therealong is transferred on to arms 96 which raise the crankshaft and rotate it through 180 degrees. The crank-shaft is then lowered so that the walking beam then transfers it further. Orientating device.-Crank-shaft 4 is carried by arm 96 carried by shaft 58 which is both rotatable and translatable vertically. Both movements are effected from motor 28. Thus, the movement of motor 28 is transferred to horizontal shaft 40. Shaft 40 carries cam 38 which engages with follower rollers 54 carried by pivoted arms 48, the arms being pivoted at 52 and being secured at 72 to shaft 58. Rotation of cam 38 therefore causes shaft 58 and carrier 96 to rise or fall. Additionally shaft 40 is connected to vertical shaft 84 by gears 86a and 86b, and shaft 84 rotates shaft 58 step by step through Geneva movement 78a and 82. Shaft 58 and carrier 96 are therefore moved step by step around the vertical axis. In this way when the crank-shaft 4 is placed by the walking beam on carrier 96 the latter is first raised and then rotated and finally descended into its original place for further transportation by the walking beam. A walking beam (Fig. 1) (not shown).-A crank-shaft 4 is progressed along the walking beam between stationary positions 8 by the engagement with the crank-shaft of elements 16 carried by frame 14 which perform a cyclic movement, the frame being raised by rollers 22 carried by reciprocating arms 20, and also being given a horizontal movement when the arms are at their highest point.
