Patent GB-2040720-A (GB)
Title: Separating gases using bipolar membranes
IPC: C01B23/00
Filed: 1979-12-13
Abstract: A bipolar membrane having elastic properties is wetted with a liquid medium, such as water, an aqueous solution or liquid ammonia. An electric field applied across the membrane is used selectively to control the transfer rate of different gaseous species through the membrane in response to an applied external electromotive force. By adjusting the external electromotive force the membrane can be controlled selectively to pass one species while rejecting other species in a mixture, so that separation between molecules of two or more gaseous materials can thus be achieved. The membrane (44) may be positioned across a cylindrical housing (42, 50) open at each end for supply and removal of gas. The wetting liquid may be supplied into an annular chamber (46) extending to the membrane surface on one side. Means (48) may supply a variable electric potential across the membrane (44). <IMAGE>

Title: Double roller metal shaping machine
IPC: B21D22/18
Filed: 1979-12-21
Abstract: A machine for forming a rotationally symmetrical body, e.g. a tank bottom, from a metal sheet includes two rollers which are moveable along an arc corresponding to the radius of the tank bottom. The sheet 1 is fixed on a supporting disc 4 on a driven main spindle. An inner, driven, profiled roller 6 supports the sheet and an outer roller 7 presses thereon such that during the formation of a large radius of curvature of the workpiece the two rollers with their supporting arms pivot together about a common shaft 12 which is supported by a cradle 13, which latter is adjustable y axially of the spindle. On forming a flange of small radius, the inner roller-supporting arm is clamped to the cradle while the outer arm continues pivoting to form a radius corresponding to the profile of the inner roller 6. In a change-over to manufacture tank bottoms of different geometry the cradle 13 is adjusted so that the distance of the pivot shaft 12 from the clamped sheet should correspond to the desired large radius of the bottom. <IMAGE>
