A reservoir for liquids spilled on the shelf is partially created by upwardly turning the front and rear edges of the shelf member. At least two end caps, which extend above the upper surface, are applied to the two side edges to complete the walls of the reservoir.

Abstract: Solid fuels, such as contaminated biomass and solid city waste, are converted into a synthesized gas by gasification and exploitation of the energy contained in the fuels. The fuel is gasified an a co-current gasogen (1), while the cinders are separated, removed and purified after a fraction of the fuels has undergone combustion and before the fuel has been gasified. Cinder purification is made by complete combustion, while the fuel that has undergone the gasification step without being completely transformed in CO is recirculated by mixing it to fresh fuel material. The process is carried out in an apparatus comprising a vertical co-current gasogen (1) and a device for the separation and removal of cinders (16,19,5,6) as well as a scorification chamber (3) where cinders are purified from accompanying fuel material by complete combustion and are then collected in a waste tank (28).

Abstract: A power transistor 1 is mounted on a metallic power supply terminal 40 within an intake pipe 20, individually and separately from an electronic circuit board 7 on which other electronic circuit element are mounted. This power supply terminal 40 acts as a terminal for electric power input and its one portion is exposed within the gas path of the intake pipe 20. The heat-generation of the power transistor 1 is effectively heat-generated by the metallic terminal 40 without giving a remarkable effect to the other circuit elements. With this, it is possible to reduce any heat effect to the other electronic circuit components due to the self heat-generation of the power transistor 1 without the additional number of parts and to effectuate the gas flow rate measuring apparatus of which measuring accuracy and reliability are high.

Abstract: A cavitation enhanced atomizing process comprises forming a flowing solution of the liquid to be atomized and a lower boiling cavitating liquid. This flowing solution is then contacted with a pressure reducing means, at a temperature below the bubble point of the cavitating liquid in the solution, to produce cavitation bubbles. These bubbles comprise cavitation liquid vapor and the bubble nucleation produces a two-phase fluid of the bubbles and liquid solution. The two-phase fluid is passed downstream into and through an atomizing means, such as an orifice, and into a lower pressure atomizing zone, in which the bubbles vaporize to form a spray of liquid droplets. The nucleated bubbles also grow in size as the so-formed two-phase fluid passes downstream to and through the atomizing means.
