Title: A reverse trunking switching network for telecommunications exchange systems
Inventor: SORGENFREI HEIKO
IPC: H04Q1/16
Filed: 1984-09-21
Abstract: 1. A switching network with reversed trunking and associated connection switch-through with connection path reversal, in particular for telephone exchange systems, wherein the subscriber terminals are connected to inputs of input subsidiary switching networks (e.g. TK1, TK6), and wherein further subsidiary switching networks (TK2, TK5) are provided, and wherein the input subsidiary switching networks (e.g. TK1, TK6) and the further subsidiary switching networks (TK2-TK5) are formed by time channel couplers, and wherein the intermediate lines which connect the subsidiary switching networks (TK2-TK5) including the input subsidiary switching networks (e.g. TK1, TK6) comprise time channel lines and, in each subsidiary switching network (TK2-TK5), are connected to associated inputs in accordance with the principle of reversed trunking with regard to the respective subsidiary switching network itself, as a result of which all the connection paths within each of the subsidiary switching networks (TK2-TK5) are reversed, and wherein, for a time channel connection switched-through via the connection paths, time channels are consecutively seized by a plurality of time channel lines in that the two time channels, seized in respect of each time channel connection and each time channel line, correspond to one another in respect of their time slots (a3, b3... a29, b29), characterised in that on the one hand for the time channels (a3, a5, a7, a11, a22, a24, a29) included in a time channel connection for one of the two transmission paths (a..., b...) switched-through in respect of each time channel connection, and on the other hand for the time channels (b3, b26, b24, b20, b9, b7, b29) arranged in series in the same spatial sequence for the other of these two transmission paths, on the basis of the path finding, two series of time slots are selected in which the time slots of the two time channels, which correspond to one another in respect of this sequence, for the two transmission paths (a..., b...) - thus of the time slots in the respective pulse frame, the two mutually-corresponding time slots from the two series time slots - have time slot values which are complementary to one another and that by virtue of the selection of time slots for the time channels for the first transmission path (a...) in a constantly ascending progression, but in the smallest possible time slot jumps from time channel to time channel, not only for this transmission path (a...) but at the same time and automatically a minimum time jump is achieved for the overall time channel connection for the other transmission path (b...), i.e. equal time jumps are achieved for the two transmission paths (a..., b...).

Title: Process for magnetic separation of metals from aqueous media
Inventor: GIBBS DUDLEY FRANCES
IPC: G21F9/18
Filed: 1984-12-19
Granted: 1988-02-03
Abstract: Paramagnetic metals are separated from aqueous media containing them in low concentration by first fixing the metals on bacterial yeast or other cells so as to render the cells magnetic, and then recovering the cells by a high gradient magnetic separation technique. The metal and the cells are contacted in the presence of a compound which is converted by the cells into a product which interacts with the metal and causes it to become bound to the cells. The process is particularly useful for removing low concentrations of highly toxic metals, e.g. uranium, from industrial effluents containing them.
