IPC: H01M8/0271
Filed: 1998-08-11
Abstract: A process for the production of an insulating component from a ceramic material for a high temperature fuel cell includes the following steps: In a first step, a ceramic material is converted into a dispersion by wet preparation with a water-soluble binder.  In a second step, the dispersion is poured to form a water-containing layer.  In a third step, the water-containing layer is converted at elevated temperature to form a rubbery layer.  In a fourth step, the binder is burnt off from the rubbery layer at elevated temperature.  In a fifth step, the layer from which the binder has been burnt off is set at elevated temperature.  In a sixth and a seventh step, the layer which has been set is processed in accordance with the dimensions of the insulating component and consolidated by sintering.

Filed: 1997-02-21
Abstract: A demultiplexer (10) includes an input stage (12) that receives a serial data stream having a plurality of m-bit sections at a first clock rate. The input stage converts successive n-bit portions of each m-bit section into a first n-bit parallel output at a second clock rate. An intermediary stage (14) receives the first n-bit parallel output and generates a second n-bit parallel output at the second clock rate. The first n-bit parallel output corresponds to a different portion of an m-bit section than the second n-bit parallel output. An output stage (16) receives the first n-bit parallel output from the input stage (12) and the second n-bit parallel output from the intermediary stage (14). The output stage (10) places the first n-bit parallel output onto an output bus (36) having a width of m-bitlines at an earlier instance in time than the placement of the second n-bit parallel output.

Title: A method of securing an architectural finish element to a surface
Inventor: ABOU-RACHED ROGER GEORGES
IPC: E04C2/30
Filed: 1994-01-07
Abstract: A method of securing an architectural finish element to a surface ultimately formed by a castable material cast about a mesh material involves securing at least one projection to a backing surface of the architectural finish element such that the projection extends away from the backing surface. The castable material is then cast about the planar mesh material. The projection is then inserted into the castable material before the castable material has set, until the backing surface rests on a surface of the castable material, whereupon the projection cooperates with the mesh material to engage therewith. The castable material is then permitted to set about the projection, thereby firmly securing the architectural finish element to the castable material and the planar mesh material.
