Title: Flue gas purificn. for combustion plant or refuse incinerator - waste gas classification uses cooling cells at continually decreasing temp., with flue gas passed downwards through cells
IPC: F23J15/06
Filed: 1991-07-15
Abstract: In purifying waste gases from large-scale combustion plants and refuse incinerators and classifying the impurities present, the flue as is passed downwards through cooling cells with continually decreasing temps. The jumps of temp. depend on the dew point of each impurity. The heat energy recovered from the waste gas is used for generating steam or hot water, whilst the cold purified gas is used for internal or external cooling procedures. The gps. of impurities sepd. are freeze dried in tert. cycles and transferred, pref. through chutes, to pressure-resistant and gas-tight vessels. O2 may be added to promote oxidn., whilst O3 may be produced by UV irradiation of the gas in a warm zone (over 30 deg.C). The dwell of the gas in each cell is controlled by ventilators, which pref. are regulated with thermostatic, velocity gauges and/or impurity sensors. USE/ADVANTAGE - All gps. of impurities can be sepd. and preclassified for economical recycling, without creating new waste problems, and the vol. of waste for disposal is minimised. CO, SOx, NOx, CO2, hydrocarbons etc. can be (partly) removed by cooling ca. 50 deg.C, whilst cooling below 0 deg. C separates all heavy metals and water vapour. The plant can be located near towns, so that the heat energy generated can be used in industry, whilst the installation of additional catalysts as de-NOx components and expensive chimneys are unnecessary.

Abstract: The invention relates to passenger car bodyshell with a front door aperture (1) bounded below by a sill (2) and in front by a pillar (3) (A-pillar). The lower region of this pillar (3) consists of the stable door pillar (6) and its upper region of the slim window frame member (8), whereby the transition lies at the level of the window railing (7). In addition, a vehicle door with a blind triangle, a "mirror triangle" (9) is used. The stable door pillar (6) is extended upwards beyond the window railing and runs behind the mirror triangle (9). This results in a shortening of the free bending length of the less stable window frame member (8). According to the invention, the door pillar (6c) is sharply inclined, whereby, on the sill side, its lower end is as far forward as possible and its upper end is taken to the region behind the mirror triangle (9). This improves both ease of entry and the rigidity of the bodyshell.

Title: Operating on materials by means of a high-energy laser beam - with focal position varied by means of deformable mirror surface, with focal spot unaltered in size, to cut thick metal sheets
Inventor: HOFFMANN PETER DR
IPC: B23K26/00
Filed: 1992-06-01
Abstract: The method for operating on materials by means of a high-energy laser beam uses a deformable mirror in front of a focussing systm to influence the beam divergence. Increases of the beam divergence takes place so close to the focussing system that the axial focal position is varied with the focal spot essentially remaining unaltered in size. The installation incorporates a variable optical system (17). The system includes a mirror surface (18) whose convexity in front of the focussing system (14) can be varied. Beam divergence is varied periodically. Focal position variation is combined with feed motions. The variable optical system takes the place of a deflecting mirror and is located in the focussing head (11). A preloaded piezoelectric actuator (19) located behind the mirror surface (18) and controlled by a voltage source (21) is used to adjust the position of effective focus (F,F'). USE/ADVANTAGE - For welding and cutting operations. In constrast to known installations (with constant focal positions), it can be used effectively to cut thick metal sheets (e.g. with thickness of the order of 20 mm).

Abstract: An inverter is to be constructed so as to minimise parasitic inductances while dispensing with supplementary circuits for the IGBT modules and, despite compact construction, to make the components easily accessible with simple assembly. For an inverter, especially a 3-point inverter with semiconductor valve components arranged on cooling units, this is achieved by the use of low-inductance multi-layer conductor routing for the general electrical connection and the production of internal electrical links in the use of multi-layer connecting tracks (51, 53) in vertical array, in which, with a continuous central main connecting track (51) which projects beyond the assembly plane of the coolers (50) and with several and at least 3 secondary connecting tracks (53) intersecting at right angles which electrically are connected to the main connecting track (51) and have the same form, an electrically and mechanically identical structure with compartmentation is achieved, whereby the branch valves and other circuit components of the inverter are assembled in phases in the compartments which are freely accessible towards the assembly plane (M) of the coolers (50) and are connected at that point to the secondary connecting tracks.

Abstract: The invention relates to a method for determining the electrical system leakage effective between power system and earth, a measuring signal being injected between power system and earth, the system leakage current flowing due to the measuring signal via the system leakage between power system and earth causing a voltage drop and this voltage drop being evaluated as output signal for determining the system leakage. To provide for reliable evaluation of the individual system leakage variables, namely the resistive and capacitive system leakage variables in any power systems, even those with low-frequency faults, it is proposed, in accordance with the invention,   a) that at least two constant-amplitude period alternating measuring signal voltages or at least two constant-amplitude periodic alternating measuring signal currents are injected as measuring signals which exhibit measuring signal frequencies (f1, f2) which are as low as possible and are within a range largely free of interference signals and differ from one another and from the power system frequency (fN), b) that an absolute-value quotient (K1 and, respectively, K2) is determined for each of the different measuring signal frequencies, in connection with which   b1) in the case of alternating measuring signal voltages to be injected, these are injected into the power system via a resistor-type power system coupler and in which case in each case the absolute-value quotient between the voltage amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal voltage and the voltage amplitude - or a quantity derived therefrom - occurring across the resistor-type power system coupler - of the associated fundamental or harmonic of the output signal is measured, whilst b2) in the case of alternating measuring signal currents to be injected, these are injected directly into the power system without resistor-type power system coupling and in which case in each case the absolute-value quotient between the current amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal current and the voltage amplitude - or a quantity derived therefrom - occurring between power system and earth of the associated fundamental or harmonic of the output signal is measured,   c) and that the two system leakage quantities (RE, CE) are determined from fixed functional relationships which in each case depend on the two measuring signal frequencies (f1, f2) and the two absolute-value quotients (K1, K2).   <IMAGE>
