Title: Hydraulic control arrangement
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B11/16
Filed: 1989-02-24
Abstract: The hydraulic control arrangement has directional control valves (11, 12, 13; 21, 22, 23) which are combined in a valve block (10; 20) and are actuated by electrically activated, hydraulic pilot-control devices (36, 37). These pilot-control devices are supplied with control pressure medium from the pressure-medium circuit of the hydraulic control arrangement. In order to raise the pressure during neutral circulation or driving load, during which the pressure in the pressure-medium circuit is lower than the required pressure, a valve device in the form of a pressurising valve (45) or a pressure balance (60) is arranged which is acted upon on the one side by the pressure in the pressure-medium feed (16, 26) and on the other side by a compression spring (47, 64) and by the pressure in a pressure space (48, 65). Via a solenoid-operated 3/2-way valve (50; 70), the pressure space is connected to the return (39, 17, 27) and, upon activation of the solenoid-operated 3/2-way valve together with one directional control valve, to the control-pressure-medium supply passage (38) connected from the feed via a pressure-reducing valve (43; 53), so that, during pressure compensation, the compression spring moves the valve device in the closing direction for choking the pressure. The solenoid-operated directional control valve and the pressure-reducing valve can also be combined in a unit. <IMAGE>

Title: Ion chromatographic method and eluant for carrying out the method
Inventor: TAKATA YOSHINORI
IPC: B01D15/04
Filed: 1989-03-14
Abstract: An ion chromatographic method using a separation column (6) which is filled with an ion exchange resin, in particular with such a resin of low ion exchange capacity, can be carried out in a stable manner over a prolonged period of time without it being necessary to replace the separation column (8). For this purpose, elution of the separation column (8) is carried out using an eluant (eluting agent) which contains a water-soluble organic compound which has the same functional group as that of the ion exchange resin. The analysis costs can thus be considerably reduced especially since the replacement of the separation column (8) has to be carried out less often. <IMAGE>
