Patent DE-3406380-A1 (DE)
Title: Apparatus for laser welding
Inventor: BURGER DIETER DIPL PHYS
IPC: B23K26/04
Filed: 1984-02-22
Abstract: The invention relates to an apparatus for laser welding. The adjustment of the distance between the focal point of the focused laser light and the surface of the workpieces to be welded and, in particular, the guidance of the focal point at the set distance from the surface along the vertical contour of the welding groove of three-dimensional weld seams, is effected by observation of the emission of radiation by the plasma buffer above the welding location. For this purpose, an optoelectronic transducer is directed continuously at the welding location and measures the radiation intensity of the plasma, which changes especially if the welding depth changes. The output signals are compared in a control unit with a set point for an optimum weld seam determined in prior test welds. In the event of deviations from this value, an actuator is actuated in order to adjust the position of the focal point. Since the welding depth is indirectly observed, the welding quality is simultaneously also monitored at the same time in addition to the adjustment and guidance of the focal point.

Patent DE-3428373-A1 (DE)
Title: Water consumption meter, in particular hot water cost allocator
Inventor: WESP JOACHIM
IPC: G01K17/06
Filed: 1984-08-01
Abstract: Consumption meter for hot water as an individual device or as a block composed of a plurality of devices, for the purpose of allocating the costs to the individual households (= hot water cost allocator). A flow sensor, preferably in accordance with the principle of the baffle element, starts a pulse generator operating in the event of the extraction of water, e.g. by magnetic actuation of a plurality of sequentially connected reed contacts. The frequency of the pulse generator is determined by the respective water throughput, either in a plurality of stages or else in proportional dependence on the extraction of water. The pulses actuate a counter which thus indicates the quantity of service water extracted. In heating systems which have a constant service water temperature, it is possible to dispense with the measurement of temperature, because all the consumers tap water at the same temperature. In older systems which have a varying temperature, this is incorporated in the form, e.g., of a temperature-dependent resistance sensor in the circuit of the pulse generator. The counters of all the devices of a domestic system can be combined at a central location. <IMAGE>

Title: Lifting appliance for the vertical transport of measuring devices, tools and similar loads in towers, in particular in telecommunication towers
IPC: B66C13/06
Filed: 1985-02-05
Abstract: The invention relates to a lifting appliance which, in a very small space inside a tower, transports measuring devices and tools from the base of the tower to the head of the tower. The load-suspension means is designed as a cylindrical hollow body which tapers to the top and bottom (like the shape of a torpedo). This load-suspension means is fastened to the carrying chain or the carrying rope of a standard lifting appliance in such a way that it hangs perpendicularly and moves up and down in the vertical direction in the interior of the tower in this position without being guided by guide rails, rollers or similar devices. The track of the load-suspension means is surrounded in the form of a circle by tensioned ropes, and in fact in such a way that the load-suspension means can hang through completely freely and without guidance. If the load-suspension means should swing out laterally in the area of the lifting path during the lifting operation, it comes in contact with some of the ropes arranged in the form of a circle and is pressed back by these ropes into the centre of the circle.

Title: Safety valve
Inventor: LANG DIETER DIPL ING
IPC: F16K17/04
Filed: 1985-03-08
Abstract: Safety valves have hitherto always been designed as angle-body valves. The diversion of flow which occurs when the valve responds due to this mode of construction leads to additional bending moments on the inlet and outlet to the housing, particularly in the case of safety valves with a large nominal diameter. To avoid the deflection forces, which can only be controlled with the use of expensive valve holders, the invention provides a safety valve, the inlet (1) and outlet (2) of which are arranged on opposite sides of the housing (3). An annular space (27) is formed between the outer surface of a hood (30) covering the spring (19) and the inner wall of the housing (3), allowing symmetrical flow through the valve body. <IMAGE>

Title: Arc furnace having a reactance loop in the heavy-current conductor
Inventor: EHLE JOACHIM DIPL ING
IPC: H05B7/103
Filed: 1985-05-10
Abstract: In the case of an arc furnace, power is supplied from a transformer via heavy-current cable to three electrode supporting arms which are arranged parallel to one another and approximately at the same level. In the region of the electrode supporting arms, the power is supplied via in each case one outer layer which is provided on an electrode supporting arm and consists of electrically highly conductive material. In order to prevent reactance losses, it is proposed that the impedances of the power supplies of the three phases be matched to one another. For this purpose, a reactance loop 1 is proposed which is constructed [lacuna] between an end piece of a heavy-current conductor section 2 which is connected to the transformer and an end piece of a heavy-current conductor section 3 which is connected to the electrode supporting arm. The end pieces 2a, 2b; 3a, 3b of the two heavy-current conductor sections are mechanically and electrically connected to one another with the aid of terminal connections 5, 6, via a lateral cross member 4 which consists, for example, of copper. The position of the lateral cross member 4 can be varied in the direction of the arrow P in order to increase or reduce the loop circumference. <IMAGE>

Title: Process for the simultaneous scrubbing of SO2 and NOx by a high sodium-sulphate content with simultaneously high residence time in the scrubber
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/68
Filed: 1985-05-15
Abstract: In the main application P3514407.6, a process is described for scrubbing preferably SO2 and NOx, in which in a scrubbing stage upstream of the NOx scrubber, the SO2 is preferably prescrubbed by limestone or hydrated lime, an SO2 to NOx ratio being established in the flue gas prior to the last scrubbing stage in such a way that SO2 and NOx can be simultaneously easily scrubbed out. For further improvement of this process, according to the invention it is proposed that the scrubbing liquid is enriched with sodium sulphate, the concentration of sodium sulphate being dependent on the NOx value and O2 content, and, namely, according to the invention at an untreated gas loading of:   1. Up to 500 mg of NOx/m<3> and 5-8 % O2 content in the gas = 30-40 g of sodium sulphate per l of scrubbing liquid, 2. 500-800 mg of NOx/m<3> and 5-8 % O2 content in the gas = 40-60 g of sodium sulphate per l of scrubbing liquid, 3. 800-1200 mg of NOx/m<3> and 5-8 % O2 content in the gas = 60-80 g of sodium sulphate per l of scrubbing liquid, 4. 1200-2000 mg of NOx/m<3> and 5-8 % O2 content in the gas = 80-120 g of sodium sulphate per l of scrubbing liquid.   The residence time of the untreated gas loaded with the SO2 and NOx to be scrubbed out is advantageously greater than 10 seconds, where the ratio L:G = 3-5 l/m<3>.

Title: Multi-stage simultaneous SO2 and NOx gas purification having scrubbing water treatment
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-05-22
Abstract: It is known to scrub flue gases of fossil-fuel-fired boilers with lime and EDTA simultaneously. This process has not established itself since the economic efficiency is characterised by too high an EDTA consumption and an unstable degree of NOx separation. To create an economic process having a high separation efficiency, it is proposed according to the invention that an SO2- and/or SO2- and HCl-prescrubbing stage is provided upstream of the NOx-scrubbing stage, which prescrubbing stage scrubs out the HCl and the SO2 as far as possible as desired, and the partially-purified crude gas is transferred to a scrubber (2), SO2 and HCl neutralization being carried out in the scrubber (1) using preferably limestone or hydrated lime, and, to support the solubility of the lime materials used, a carboxylic acid, preferably formic acid is added, which does not hinder the oxidation of CaSO3 to CaSO4, where, contrasting with this gas treatment, a complex is formed in the stage (2) from the liquid sodium hydroxide solution, EDTA and/or NTA mixed with a carboxylic acid, but in this case, in contrast to the first scrubbing stage, an oxidation-inhibiting carboxylic acid, for example tartaric acid, is added to the mixture to prevent too early an oxidation and to reinforce the iron complexation of FeII to FeIII and to establish the negative redox potential, sodium dithionite or sodium sulphite and/or pyrosulphite is used. <IMAGE>
