Abstract: The invention relates to a modified planar cell with a solid-oxide solid electrolyte, a gas-diffuse anode, a cathode, a metal or oxide current path and a current-gas supply. The supporting solid electrolyte of the cell is in the form of a corrugated plate consisting of corrugations. In cross-section, the corrugations of the plate constitute an isosceles, identical-height trapezium, without a larger lower base with holes. The holes are formed on one side in the upper part of each corrugation, for supplying one of the reagents, e.g. fuel in case of a fuel cell. The corrugations are connected to one another at their base in order to form gas space channels of the cell. The gas space channels are in the form of inverted isosceles trapezia without a larger upper base and the angle ? at their smaller base is 0.1 to 89.9°. The corrugated plate is connected to two opposing walls, a front wall and a rear wall.

Abstract: Disclosed herein are an injection foam molding apparatus for manufacturing one-piece shoes or soles and one-piece shoes manufactured using the same. A thermoplastic resin is injected into top and bottom molds in a state in which the top and bottom molds are coupled with a middle mold and is then pressed to form the upper and lower parts of a shoe, the middle mold is separated therefrom, and then the top mold and bottom mold, including the upper part and lower part of the shoe, respectively, are pressed, thereby forming the upper part and lower part of the shoe into one body. The injection foam molding apparatus is advantageous in that, since functional one-piece shoes or soles, having various colors, hardnesses and specific gravities, and having excellent feeling and durability, can be manufactured using different materials by one apparatus, working time is decreased, and productivity can be increased.

Abstract: A forming plate for a bakery machine is provided having a working surface area on an upper side with an array of forming bowls provided concentrically in circles thereon. The bowls each have a system of concentric annular edges beginning at an outside and extending to a center. From each annular edge there extends, in the direction towards the center, an annular flank oriented perpendicular to the underside of the forming plate. This flank is divided into two sequential annular ramp sections via an intermediate transition zone. The annular ramp section which extends from the annular edge viewed in the direction away from the center has an angle of inclination (&agr;1) which is greater than the angle of inclination (&agr;2) of the immediately following annular ramp section. This achieves an acute-angled, knife-like shaping of the ramp sections which follow on from the annular edge, as well as from a considerable height of the annular edge above the flank base.
