Provided is a master printed circuit board (PCB). The master PCB includes panels defined by grooves cut in the master PCB, the grooves separating one panel from another. A final PCB is formable via use of one or more jumpers, wherein the jumpers are configured to extend across at least one of the grooves to electrically connect one panel to another panel. The electrically connected panels form the final PCB.

The invention is a cooling system comprising adjacent cooling deltas () being cooled by a cooling air and being arranged along a path (). The cooling system is characterized by comprising cooling deltas () arranged in groups (), the cooling deltas of a group () being arranged essentially in the same orientation and define an essentially straight path-section, wherein the path-sections of adjacent groups () form a zigzagged path ().

Cooling system

The invention is a hybrid condenser having a direct contact condenser segment () and a surface condenser segment () arranged in a common condensation space. The hybrid condenser includes a surface condenser segment () arranged downstream the direct contact condenser segment () in the direction of steam flow or below the direct contact condenser segment (), and a water guiding element () ensuring that the cooling water and condensate mixture generated in the direct contact condenser segment () flows downward avoiding the surface condenser segment ().

Air-cooled condenser

In a cooling apparatus operated by ambient air and an agent to be cooled which can have solid state at atmospherical temperatures, a housing such as a cooling tower (100) with air inlets and air closure means at the air inlets and large surface heat exchangers (3) arranged within the cooling tower (100) at its air inlets and divided into groups or sectors being in parallel connection are provided, with which the agent is cooled by the air streaming through the large surface heat exchangers (3). At least one pre-heating heat exchanger (20) is arranged in the air space (29) of each sector of the large surface heat exchangers (3), and the pre-heating heat exchangers (20) are in parallel connection with the large surface heat exchangers (3) of each sector.

Ammonium nitrate is mixed, in a weight ratio of higher than 1:5, with a melt containing ammonium hydrogen sulfate and ammonium sulfate respectively present in the melt in a ratio of at least 4:1. The resultant mixture is subjected to thermal decomposition at 200-240 degrees C to produce nitrous oxide.

Process for the production of nitrous oxide

A heat exchanger in a close cycle gas turbine power plant has, on its heat abduction side, a system of cooling units connected to it by means of which the efficiency of the plant is considerably increased. Such units consist of evaporators and vapor turbines with condensers and air coolers, the vapor turbines being driven by vapors generated in the evaporators. The latter, in turn, are heated by the heat abduction side of the heat exchanger in the main cycle. The exhaust vapors are precipitated in condensers and cooled down by air coolers and recoolers and partly circulated back to the heat abduction side of the heat exchanger in the main cycle.
