Abstract: 482,570. Bending sheets. ELKINGTON, H. D. (Cairns Metals Corporation) Aug. 5, 1937, No. 21642. [Class 83(iv)] In a process for imparting compound longitudinal and transverse bends to sheets a carriage draws the sheet through stationery curved rolls while curved rolls are moved over the sheet in the opposite direction. The sheet 65 is clamped to a carriage 64 moved by chains 72 on a table 54 by an electromotor 68. Concave and convex rolls 19, 18 are mounted in a fixed frame 10 and similar rolls 27, 28 are carried in arms 29 swung about pivots 31 by an electromotor 32. The rolls 27, 28 are carried in slides moved radially of the arms 29 by an electromotor 44. The curved rolls 27, 28 and 18, 19 are mounted in frames which can be reversed in the frames 29, 10. The sheet may be flanged and knurled rolls 94 driven by the chains 72 engage the flange and assist the feed. The clamp 65 is lowered on the carriage 64 as the bending proceeds by an electromotor 82. In operation, the sheet is clamped to the carriage 64 and the motors are started to pull the sheet through the rolls to effect the transverse bend and to lower the clamp. The arms 29 are swung anticlockwise, Fig. 2, to effect the longitudinal bend. Radial movement of the rolls' 27, 28 by the electromotor 44 modifies the longitudinal bend. The angle of the table 54 may be varied from a hand wheel 62. In repetition work, the motors may be controlled by switches 98 adjusted along the table. As the carriage moves over the table the switches are closed by a shoe 99 to vary the resistance and the speed of three phase motors, Fig. 9 (not shown). The rolls may be heated by oil, steam, gas jets or electric resistance coils. British Specification 333,675, [Class 83 (iv)], and U.S.A. Specification 1,820,936 are referred to.

Abstract: 572,350. Ignition timing control. UNITED AIRCRAFT CORPORATION. Dec. 24, 1943, No. 21680. Convention date, Dec. 23, 1942. [Class 7 (iv)] [Also in Group XXIX] An ignition timing control device for an internal combustion engine 26 has servo motor means, responsive to the pressure rise across the supercharger 10, for retarding the ignition at low or high values of the pressure rise and advancing it at intermediate values of the pressure rise. The two magnetos 12, 13 are driven from an engine shaft 32 through a shaft 36 carrying bevel-gears which drive loose compound bevel gears 46, 50, Fig. 2, on each magneto shaft 52. From gear 50 the drive is transmitted to a bevel gear 60 keyed to the .magneto shaft by bevels 54 carried by a cage which is movable around the shaft 52 to alter the timing by means of arms 76 pivoted to the bar 72 of a yoke operated by the piston 64 of the servo motor. The latter comprises cylinders 66, 68 fitted with plugs provided with piston stops 82, 80, the piston being normally urged against the stop 80 to give retarded ignition by spring 78. The servo control valve 104 is actuated by a spring-urged diaphragm which is subjected on its upper and lower sides to the outlet and inlet pressures, respectively, of the 'supercharger. At moderate engine power corresponding to cruising speed the diaphragm is in the intermediate position shown in Fig. 1, thus applying pressure fluid from line 94 through line 84 to cylinder 68 to give advanced ignition timing. When -the diaphragm is raised by fall in the supercharger pressure rise fluid flow is along line 86 to cylinder 66 to cause retarding of the ignition. Also when the diaphragm is lowered when engine operates in upper part of its power range pressure fluid enters line 86 and again produces retarded ignition.
