Inventor: DELLWIK CARL
IPC: C01B3/06
Filed: 1916-08-30
Abstract: 125,596. Dellwik, C., and Cutler, S. Aug. 30, 1916. Hydrogen.-In preparing hydrogen from a mixture of hydrogen and air, such as the waste gases from balloons, the mixture is used as the reducing-gas in the process of alternate reduction of iron oxide or other suitable material, and re-oxidation by means of steam with liberation of hydrogen. The mixture of hydrogen and air is passed into a gas-holder G and is circulated by a pump E through a closed circuit comprising the gasholder G, devices WS, ws which prevent a local explosion from spreading, a retort C containing iron oxide, and a scrubber SC. The circulation is continued until the gas becomes inactive. A supply of steam generated from the water condensed in the scrubber SC or from another source is then led into the retort C, and the hydrogen obtained is passed through a condenser K to a gas-holder H. If an explosion occurs in the retort C during the reduction, the safety-valve SV lifts, and water is forced from the water-seal vessel WS to form a second water-seal in the vessel ws.

Filed: 1962-04-03
Abstract: 993,570. Coils for dynamo electric machines. ALLMANNA SVENSKA ELEKTRISKA A.B. April 3, 1962 [April 7, 1961], No. 12679/62. Heading H2A. In a commutated winding having more than one turn per coil, the turns being placed one above the other in the slot, overhang width is conserved by bending them concentrically one within the other instead of side by side, this being made possible by separating the turns of the coil in the slot by turns of another coil. Thus in the conventional arrangement, Fig. 1, the slot-positions of the coil are h4, v2, h3, v1 in sequence, this necessitating placing the overhangs side-by-side at B. According to the simplest form of the invention, Figs. 3 and 4, the sequence is h2, v3, h4, vl, the intervening spaces being filled by other coils. This arrangement enables the turns to be wound one within the other, Fig. 4, to conserve peripheral space. The coil may have several turns (Figs. 7 and 8, not shown), or may occupy several slots (Figs. 5 and 6, not shown).
