Abstract: An apparatus for growing biological mass has a container for accommodating a biological mass in liquid to be grown in presence of light, a plurality of light sources in an interior of the container, a first movable plate which has passages for the light sources and which is reciprocatingly movable along the light sources to clean the latter, the first plate also having a first openings permeable for the liquid and for the biological mass, and a second plate located under the first plate and configured so that it is permeable for water and small algae fraction which have still to be grown but not permeable for the biological mass with fully grown algae, so that for discharging the biological mass the first and second plates are placed over one another and together moved toward a discharge so that the water can pass through both plates, while the biological mass is held on the first plate and moved toward the discharge to be discharged outwardly.

Abstract: An apparatus for growing biological mass has a container for accommodating and growing a biological mass, a unit for supplying liquid in the container, a unit for supplying CO2 in the container, a unit for supplying a feedstock in the container, and a cavitating device arranged so that a liquid is supplied from the unit for supplying liquids directly into the cavitating device and CO2 is supplied to the cavitating device directly from the unit for supplying CO2, so that in the cavitating device a mixture of liquid and CO2 is produced with a cavitation process, the cavitating device being connected with the container for supplying the mixed CO2 and liquid subjected to cavitation into the container.

Abstract: A system for electric testing PCB/MCM before and after assembly. The system uses energy taken from a heating source, timely applied at certain ports of the PCB/MCM (entry ports). The energy is defused through the board inner layer tracks terminating at the end of the channel tracks of the PCB/MCM (exit ports). The rate of energy diffusion on the board is measured at the terminating ports in the time domain. The thermal emission is measured by a spectrometer that conducts infrared scans and analyzes the PCBs energy spectrum. Measurements can be taken as discrete measurements or as integrated measurements. The measurements results are compared with the pre-memorized values of a group of patterns that represent respective golden board. Defect analysis is automatically achieved based on learned defect test patterns.
