Patent AT-E684-T1 (AT)
IPC: F23G5/00
Filed: 1979-12-03
Granted: 1982-02-15
Abstract: A method and apparatus for the heat treatment of industrial wastes wherein at least some of the constituent materials of the wastes are subjected to combustion and/or to pyrolysis to produce flue gases and, in some applications, a residue. The supply of an oxygenated combustion-supporting gas to the wastes is regulated as a function of at least one sensed predetermined characteristic of the flue gases. The oxygenated gas may be a mixture of air and substantially pure oxygen, the feed rate of one or both of these being regulated in response to the sensed temperature and/or oxygen content of the flue gases. Such regulation maintains the oxygen content of the flue gases within the range of from 0 to 7%; and the temperature of the flue gases may be maintained from 400 DEG  to 1200 DEG  C. and, preferably within a range of 50 DEG  C. in this region.

Abstract: Various embodiments of photoreactors are disclosed which have at least two irradiation chambers with a window therebetween. Ultraviolet radiation is introduced into one of the chambers at a side opposite the window so that it passes through that chamber, through the window and into the other chamber. The fluid medium to be purified is passed through the chambers and subjected to the radiation while in the chambers. The flow of the medium is through the chambers in series. The chambers are optimized in depth with respect to efficiency in terms of the flow-dose rate. In a two chamber photoreactor traversed by parallel radiation the maximum is at a total absorption of about 70 percent and at an absorption of about 27 percent in the chamber immediately adjacent to the radiation source. In an annular two chamber photoreactor with an elongate radiation source extending along the axis thereof the corresponding data are 45 to 65 percent and 16 to 25 percent, respectively. In an immersion type three chamber photoreactor of analogous configuration the corresponding data are 60 to 80 percent and 14 to 20 percent, respectively.

Abstract: The invention relates to a process for the purification of wet-processed phosphoric acid with the aid of organic solvents which are immiscible or only partially miscible with water, the sulfate ions being removed by addition of barium compounds. The purification is carried out in an n-stage extraction installation, where n is equal to or greater than 5. The barium compound is added to the phosphoric acid to be purified, and the resulting mixture is fed to the top of the extraction installation, in which the organic solvent phase is dispersed in the aqueous phase. The sulfuric acid is led in counter-current fashion to the phosphoric acid by adding it to one of the stages n=4 to at most n-1.

Abstract: A power supply system for operating fluorescent lamps in a hazardous atmosphere comprise a 1 kHz to 500 kHz constant current power supply (24 to 28, 31, 32) which feeds primary windings of transformers (3, 4, 5- - -N) which are connected together in series. Fluorescent lamps (11,12,13---Z) are connected across the transformer secondary windings. A voltage control circuit (29, 30) is connected to the power supply output to ensure that the amount of electrical energy supplied to the transformers cannot ignite the atmosphere under any normal or fault condition. Capacitors (6, 7, 8- - -X) are connected in series with the transformer primary windings to reduce the circuit reactance so that, for a given level of supply voltage, an increased number of lamps can be fed with starting voltage. Due to the substantially constant current which is fed througt the transformer primary windings, the situation cannot occur that the firing of one lamp prevents the others from firing. The transformers preferably include windings to feed heaters of the lamps. The lamps may be disconnected from the supply by removal of the transformer cores or by separation of the windings.

Abstract: The invention relates to an apparatus for pressure die casting of metals and alloys involving the action of increased gas pressure on the solidifying melt. In this apparatus, the gas is pressurized automatically during the stroke of the press and pressurized gas at elevated pressure is applied to molten metal in the die cavity immediately after the closing of the die. For this purpose, the apparatus comprises a hydraulic press including a cylinder and a piston slidably mounted therein, which piston divides the cylinder into a first and second chamber. The first chamber is in communication with a source of pressurized liquid and the second chamber is in communication with a gas retaining cavity disposed in the piston rod of the piston. A press plate and die having at least one die cavity is rigidly mounted on the piston rod. The cavity of the die is connected by means of corresponding valves to a supply reservoir with gas under low pressure. The gas retaining cavity within the piston rod is filled up to a fixed level with working liquid from the hydraulic system of the press. The bottom part of this cavity is connected to the second chamber of the pressing cylinder below the piston. This second chamber is connected to the hydraulic system of the press by means of a valve. The upper part of the gas retaining cavity is connected simultaneously by means of a check valve to a supply reservoir for gas and by means of a shut-off valve to the die cavity. The die cavity is connected by means of another shut-off valve to the atmosphere.

Abstract: The chair has a seat plate (2), which is mounted rotatably on the seat support (1) at the attachment point (3). The backrest support (4) is connected in an articulated manner by an arm (5), extending below the seat plate (2), on the one hand to the seat plate (2) and, on the other hand, by means of a double-jointed lever (10') also to the seat support (1). A gas spring (7), which can be arrested in any desired positions, acts on the backrest support (4) and has the tendency to bring it into the position drawn in continuous lines. When the chair is moved out of the latter position into the position drawn in dot/dashed lines, the seat plate (2) swivels only approximately half as far as the backrest support (4). In this case, it is essential that, despite the synchronous movement of the seat plate (2) and the backrest support (4), no effects arise which cause the shirt to be pulled out. The path of the gas spring increases progressively as a function of the rearward movement of the backrest, with the result that the force acting on the backrest due to the gas spring (7) is likewise greater with the increased inclination of the backrest. <IMAGE>
