Abstract: 1,177,091. Curving; rolling. KAUFMANN TOOL & ENG. CORP. 9 Dec., 1966 [9 Dec., 1965], No. 55360/66. Headings B3E and B3M. A two-roller bending machine, for bending a metal sheet without producing flats, includes a driven roller 22 provided with a covering of urethane rubber, and a parallel, relatively rigid, roller 24 between which rollers the sheet is passed. A pivoted arm 54, which supports the end 106 of the roller 24 during bending, is movable by a fluid-pressure cylinder 68 to the position shown after the bending step, to allow removal of the sheet. The roller 22 is moved towards the fixed roller 24 before rolling commences (and after the arm 54 has been moved to support the roller 22 and thus actuated a switch 81) by means of a fluid pressure cylinder 88. The cylinder causes a slide 92 to be raised, which in turn operates toggle mechanisms through struts 138 to raise the roller relative to fixed supports 14 and 16. The final position of the roller 22, and thus the pressure with which it presses against the fixed roller, is adjustable by means of screws 134, an indicator 162 displaying the adjusted position of the screws. A tubular sleeve 180, Fig. 9, having an embossed outer surface may be positioned on the roller 24 to produce a workpiece having embossed surfaces. Alternatively a smooth sleeve may be used which acts as a support for the workpiece and determines its radius of curvature. The rollers, Fig. 4, are similarly constructed, apart from the urethance sleeve 120 on the roller 22. A central shaft 100 is supported at its ends and carries two bearings 104. A stepped outer sleeve 102 is mounted for rotation on the bearings, while inner sleeves 100c locate the bearings in position.

Abstract: 1,174,787. Aerials. THOMSON-CSF. 20 Dec., 1966 [21 Dec., 1965], No. 57059/66. Heading H4A. In an antenna radiation lobe scanning system, the antenna is formed of an array of elementary antennµ, p.q, each of which has a phase adjuster, 1.p.q in the associated feeder, 2.p.q. Each adjuster provides a predetermined incremental phase charge in response to a computer, 3, to effect the required lobe movement. The computer has inputs 31, 32, 33 corresponding respectively to the desired elevation S o , azimuth g 0  and operating wavelength #. The incremental phase changes do not all give the required lobe direction accurately and error correction is effected by controlling the sign of the incremental changes to each source so as to bring the algebraic sum of the changes, for the source, closest to the required total phase change. The sign control of the incremental phase changes is effected by a code stored in the memory, 4. The sign of the phase errors during transmission is the reverse of that of the phase errors during reception.
