Abstract: The invention relates to thermosetting, cathodically depositable, aqueous electrocoating compositions which are produced by reacting a nitrogen base-containing binder, which contains tertiary amino groups and primary and/or secondary OH groups, with metal compounds, which are sparingly soluble or insoluble in water, of cobalt, copper, lead, nickel and/or manganese at temperatures between 100 DEG  C. and 150 DEG  C. under an inert gas. The resultant products are subsequently protonated with an acid and diluted with water in a manner known per se to yield electrocoating paints having a solids content of from 5 to 25% and pH values of 5 to 8. Octoates, naphthenates, borates, and also acetyl acetonates are preferred to be used as the metal compounds which are sparingly soluble or insoluble in water.

Abstract: A switching network for selectively connecting at least one input time-division channel on an input link (IL) to at least one output time-division channel on an output link (OL). The network is organized around a closed-loop link (10) on which circulates a multiplex message carrying 512 time-division exchange channels. The input and output links (LE and LS) are respectively multiplexed onto an input multiplex link (IML) and an output multiplex link (OML) which are coupled to the closed loop (10) by a switching module (SM). Each switching module comprises an input buffer (IB), an output buffer (OB) and a local buffer (LB) the addressing of which is selectively controlled by a time slot counter (CRT) or a corresponding pointer memory. So-called "broadcast" connections coupling one input channel to several output channels, and "in-cast" connections coupling several input channels to one output channel, can be established. Each of these connections uses only one exchange channel.

Abstract: A gravitational separation device is provided and the process is provided involving a packed column containing a packing material and having a device for vibrating the packed column and the particles. The gravitational separation device allows for efficient and effective separation of solid particles having different densities. The process preferably involves conditioning an aqueous pulp of mineral ore with a dispersant and feeding the dispersed aqueous pulp into an inlet into an intermediate section of the packed column and forming a high density bed of high density particles in a lower portion of the column, and forming a low density bed of low density particles in an upper portion of the column. Tailings are removed from the upper end of the column and concentrated mineral ore having reduced levels of gangue are removed from the bottom of the column. The device and process are especially useful in the separation of silica particles having small particle sizes from iron ore particles having small particle sizes.
