A device for impeded osmotic influences

For realization of this project different practical and theoretical methods shall be used altogether:

Using the device [4] we shall examine the so called by us impeded osmosis [3, 4]. This is osmotic process at which the natural increase of the solution volume is obstructed by an external mechanical influence causing an increase of the pressure. By means of this device, there is an impeded osmosis in selected stationary influences – temperature, external pressure, EMF etc.

The device has a compact construction, providing easy functioning and reliability of exploitation (Fig. 1). It consists of a body of a closed construction, made of high quality dielectric material. On two opposite external sides of the corpus two identical electrodes connected to a controlled source of high voltage, which creates static or alternating EMF are placed. In the body, there are two identical graduated reservoirs, communicating on the bottom side through a fluid-conducting connection. For realizing OP between the solutions in the two reservoirs, a selective semi-permeable membrane is built in the fluid-conducting connection.

 

Fig. 1

A mobile piston with a stem is introduced in either reservoir, by means of which the evaporation is blocked and the pressure in the liquid is controlled. The two pistons and their stems are identical in size and mass. Valves could be mounted in both pistons or in any other appropriate place to allow the evacuation of air from the reservoirs and the fluid-conducting connection. The reservoirs with the pistons and the stems, the membrane and the fluid-conducting connection allow easy assembling and disassembling, when cleaning after usage, or replacement, if needed.

 
 

The outer end of the stem of each piston is fixed to a tensio-sensor for measuring the force creating the pressure in the respective reservoir. Both sensors are connected to indicators reading the values of the pressure-generating forces.

The device is placed in a thermostatic chamber to provide the desired temperature of operation. Each of the reservoirs is supplied with an appropriate inertialess gauge, connected to an indicator for the temperature. The whole device is screened to avoid electromagnetic influences on its functioning, as well as hazardous effects upon the operator.
