Title: A method of recovering a desired amino acid and method of recovering l-lysine from an aqueous solution
Inventor: FECHTER WOLFGANG L
IPC: C12P13/08
Filed: 1994-11-18
Abstract: A method of recovering a desired amino acid such as L-lysine from an aqueous solution containing the desired amino acid and impurities, includes the steps of passing the solution over a primary cation exchange resin to adsorb the desired amino acid onto the resin at a pH lower than the isoelectric point of the desired amino acid, eluting the desired amino acid from the resin using a suitable eluent having a pH higher than the isoelectric point of the desired amino acid to produce a first solution, passing the first solution over a secondary cation exchange resin to adsorb one or more of the impurities and to produce a second solution leaving the resin, collecting the second solution until the ratio of the concentrations of a selected impurity to the desired amino acid reaches a chosen value to produce a third solution which contains a lower level of impurities than the first solution, and recovering the desired amino acid from the third solution. This method avoids the need for a costly crystallisation step to produce a final product.

Patent CH-654715G-A3 (CH)
Title: Electronic watch
Inventor: USHIKOSHI KENICHI
IPC: G04C10/04
Filed: 1979-07-27
Abstract: The arrangement of the watch is such that the moving of the crown (101) from the position (101a) to the position (101c) locks the seconds hand (102) and enables the hour hand and the minute hand to be moved by rotating the crown. On returning the crown from the position (101c) to the position (101a), the seconds hand and the gearing are once again driven by the motor. Another mode of operation of the control device consists in pressing on the button (103). In this case, the seconds hand adopts an abnormal movement. If during this preparatory state the crown is pulled out to position (101c), the seconds hand is locked and the position of the hour hand and of the minute hand can be corrected, but when the crown is pushed back to position (101a) the seconds hand then begins by making up the time for which it was stationary and the motor resumes its normal mode of advance once the elapsed time has been made up. <IMAGE>

Title: Article made of mineral wool, process of its production impregnation material therefor and its use
Inventor: KUMMERMEHR HANS
IPC: D06M11/00
Filed: 1994-11-11
Abstract: A mineral wool article including a mineral wool layer, at least a region of which extends from at least one surface of the mineral wool layer into the mineral wool layer to an impregnation depth t. The region of the mineral wool layer includes individual fibers and is impregnated with an impregnating substance which adheres to the fibers and encloses the fibers without sealing gaps defined between the fibers so as to permit the surface of the mineral wool layer to retain an open surface structure. The gaps between the fibers in the region include bridge formations of the impregnating substance, which bridge formations are configured to permit air to penetrate through the mineral wool layer without essentially being impeded and to trap solid particles and thereby prevent emergence of the particles from the surface of the mineral wool layer. The impregnating substance provides the article with a soft and warm touch.
