The intermediate reservoir can be connected to a gas recovery station.

Abstract: A laser apparatus with a laser oscillator and a subsequently connected la intensifier which has an inlet region for the laser beam to be intensified coming from the laser oscillator and an outlet for the intensified laser beam and which is provided with a folding mirror that lies opposite to the inlet region for the laser beam to be intensified. The inlet region for the laser beam to be intensified is an opening in a further folding mirror which is located opposite to the other folding mirror. The outlet for the intensified laser beam likewise is an opening in one of the two folding mirrors. The opening width of the inlet opening and the outlet opening in relation to the mirror surface of the particular folding mirror is small. The cross section of the laser beam inside the laser intensifier is at least partially greater by a multiple than in the region of the inlet opening and outlet opening.

Abstract: An inductor is connected in parallel with an electrical load which, together with the capacitive components of the load, forms a resonant circuit. An auxiliary inductance coupled to the aforesaid conductor is energized periodically. During the oscillations, the resonant circuit delivers the energy to the load. The power dissipation of the switches is very low, due to the auxiliary inductance and the resonant circuit. The high-voltage generator is particularly suitable for gas lasers.

Abstract: A method of and an apparatus for the regeneration of adsorbent particles containing carbon in which the particles are introduced into downwardly moving shafts of a fluidized quartz sand bed spaced along a regenerator and are then deflected downwardly at the bottoms of the shaft by rhomboidal guide segments. The regenerated particles are withdrawn in a gas stream from above the bed and the gas is separated from the particles.

Abstract: Solids from a liquid containing heavy metals are filtered by first degassing the solids-laden liquid and then subjecting the degassed liquid to sedimentation to remove large particles and subsequently intermediate size particles. The suspension of fine particles is then passed in counterflow to a moving bed of granulate, especially black peat, to which the particles tend to adhere externally and internally. Clear liquid is removed from the top of the moving bed and the granulate is washed after being withdrawn from the bottom of the bed and is recycled to the moving bed.

Abstract: A carbonaceous adsorbent impreganted with elementary sulfur is produced by mixing the adsorbent with elementary sulfur in a quantity required for the desired impregnation, heating the mixture to a temperature between 120.degree. and 300.degree. C., maintaining this temperature over a time period of between 1 and 40 hours, and then cooling the mixture.

Abstract: A method is disclosed for the adsorptive removal of H.sub.2 S from gas mixtures in C-containing adsorption agents with 1-80 bar pressures and regeneration, employing pressure lowering and/or temperature change and simultaneous rinsing with an at most negligibly absorbable component of the gas mixture. A carbon molecular sieve of fossil and/or bituminous fuel is used, with for pore diameter less than 10 nm a pore volume of 15-25 cm.sup.3 /100 g, and micropore volume in pore diameter range 0.35-10 nm less than 10 cm.sup.3 /100 g. The inner surface of the molecular screen can be freed of surface groups capable of reacting with the H.sub.2 S by aftertreatment with reducing gas.

Abstract: A bottom for a fluidized bed conveyor is composed of a plurality of members provided with openings and located in contact with each other so that their points of contact are gas impermeable at least during operation of a fluidized bed. The openings may be formed as circumferentially closed holes and/or as laterally open recesses. The members may laterally abut against each other, or may be provided with interengaging lateral projections. The members may be located so that at cold temperatures small intermediate spaces remain therebetween, which spaces are closed during operation as a result of thermal expansion of the members under the action of high working temperatures. Bracing element or elements may be provided which urge the members toward one another.

Abstract: A method for the production of acetylene from coal and hydrogen is provided by electric arc heating. The coal has a content of volatile components (i.waf) from about 25 to 44 percent and a content of organic oxygen (i.waf) of less than 9 percent and is ground to a diameter of less than 0.5 mm. The coal is then separated into two to four grain size fractions and one of the grain size fractions is loaded on a hydrogen containing gas. The gas carrying the coal is heated by way of an electric arc with an energy of from about 5 to 20 kJ/l (in normal state). The ratio of electric power employed to coal stream is from about 4,000 to 40,000 kJ/kg coal. The coal is heated for a time duration about inversely proportional to the third root of the specific outer surface of the coal gain fraction. The resulting product gas is quenched with cold liquid hydrocarbons, with hydrogen or water. Acetylene yields of up to about 0.41 kg acetylene per kg coal can be obtained.

Abstract: Apparatus for purification of waste water includes an upright adsorber filled with active carbon passing in downward direction through the adsorber while waste water flows in upward direction therethrough. A distributing arrangement is produced at the region of the lower end of the adsorber, into which waste water is fed, and constructed to assure a substantial even distribution of the waste water during its upward flow through the carbon column. A regulating arrangement is provided to regulate the flow of the carbon through the adsorber in dependence on the concentration of the organic contaminants adsorbed by the carbon.
