Title: Improvements in or relating to reinforced structures made from thin sheet material
IPC: A63H27/00
Filed: 1945-12-07
Abstract: 604,885. Making toys, rods, tubes and sheets. SIMPSON, J. Dec. 7, 1945, No. 33188. [Classes 83 (ii) and 83 (iv)] [Also in Groups VII, XV, XVI and XXXIII] Bending.-Sheets of metal for making model aircraft, toys, e.g. boats, buildings and road vehicles and for making cartons, are reinforced by marking or scoring the sheet in intersecting groups of fold lines l, t, Fig. 1, incisions being made in the sheet at 6, 7 to enable it to be folded about the lines to form upstanding stiffening ribs L, T, Fig. 3. The internal surface of the ribs may be held together by metal clips or by welding, soldering or brazing. The ribs are further folded about the line 5 so as to form flanges 8, 9 and overlying flanges may be secured to one another. The sheet may be folded at selected ribs to form a tube of any polygonal section as shown in Fig. 4, to constitute, for example, the fuselage of a model aircraft. The fold lines of a group may be parallel or converge as shown in Figs. 11, 12, to control the height and contour of a rib L in making the aerofoil section of a wing. In this modification, Figs. 11, 12, the transverse ribs T, T<SP>1</SP> are constituted by flaps cut from the sheet and bent up to form the ribs.

Title: Improvements in solid oxygen-ion electrolyte cell for the dissociation of steam
IPC: C25B9/17
Filed: 1969-07-04
Abstract: 1,242,469. Solid electrolyte cell for generating hydrogen. GENERAL ELECTRIC CO. 4 July, 1969 [5 July, 1968], No. 33879/69. Heading C1A. [Also in Division C7] H 2  is generated from water vapour in a solid oxygen-ion electrolyte cell 13 by electrical dissociation at the cathode 12 where O 2  is removed through the non-porous solid electrolyte layer 14 as ions and released again at the anode 16. If O 2  is not desired as by-product, it may be reacted at the anode with reducing gas, such as a CO/H 2  mixture from partially oxidized hydrocarbon fuel e.g. methanol vapour/  steam mixture. A D.C. source 17 may be connected to the electrodes 12, 16 but is unnecessary if excess reducing gas is supplied, the cell being self-driven by simply electrically connecting the electrodes. Dissociation may be assisted by electric heating or fuel combustion preferably to heat the cathode above 800 C. The electrodes may be of Ni or Ca or a Ni/ZrO 2  cermet either side of an iron-doped, yttriastabilized ZrO 2  electrolyte, in the form of separate concentric annular segments (21, 23, 24, Fig. 2) arranged in series as a vertical gas-tight tubular structure down which H 2 O vapour is introduced with a CO/H 2 /N 2  mixture arranged outside. For producing both H 2  and O 2 , porous Pr cobaltate may be used for the anode resistant to oxidation. The electrolyte may be of ZrO 2  stabilized with CaO, MgO or a mixture of rare earth metal oxides, or ceria-doped lanthanum oxide.
