Title: Process for retrofitting a T-pipe-shaped connection fitting, and device for carrying out this process
Inventor: LEHMANN WERNER
IPC: G01F15/18
Filed: 1985-11-23
Abstract: A description is given of a process for retrofitting a T-pipe-shaped connection fitting, connected to a supply line and discharge line, for the purpose of exchanging a hot-water cost distributor, flanged on the end surface of the central branch piece, through which a channel passes, of said connection fitting, for a flow meter. In this process, the hot-water cost distributor, after blocking off the supply line and discharge line, is removed from the branch piece and a drilling device is placed on the latter. Thereafter, the supply line alone is opened and drilling work is carried out on the branch piece. The water flowing into the connection fitting can then flow into the drilling device, via the drilling tool, and then flow out again, via a discharge channel in said drilling device, and thereby flushes any drilling waste completely out of the channel to be drilled. It is thus ensured that, when the discharge line is opened after retrofitting, no drilling waste can pass into line valves and destroy their sealing action.

Title: Process for eliminating harmful materials downstream of wet quenching in coke quenching towers, with simultaneous water treatment
Inventor: HOELTER HEINZ DIPL ING
IPC: C10K1/20
Filed: 1985-11-26
Abstract: The Main Application P 3538138.8 describes a process for getting rid of emissions from a coke quenching tower, wherein the quenching hood is located downstream of the actual quenching tower and, using condenser arrangements with heat exchangers, the gas volumes are sprayed with SO2-scrubbing liquids, whilst at the same time the condensation restricts the gas volumes to a minimum, after which the gas volume bearing water vapour is fed to a deduster (dust precipitator). In order to improve the process of the main application further, the invention proposes that downstream of the quenching tower a dry chemisorption filter unit is employed, which is charged with chemisorbing and at the same time moisture-absorbing materials. The chemisorption masses fed to the chemisorption filter consist of a core material which is reinforced with acid-binding absorbents, in order to take up gaseous harmful materials such as SO2, H2S and CN [sic] and furthermore brings about the conversion of substances constituting an NOx nuisance.

An especially simple and cost-effective production of a locking catch of this type is thereby possible.
Patent DE-3607739-A1 (DE)
Title: Template
Inventor: EIFLER HERMANN-JOSEF
IPC: B05B12/24
Filed: 1986-03-08
Abstract: The invention relates to the improvement of a template, such as is used as an aid for so-called ornamental work in the painting or lacquering trade, namely for the subsequent application of decorative borders along window or door reveals, of ornamental borders above skirting and wall surfaces, of ceiling friezes and much more. Until now such templates have only been produced with a short length and from relatively thick and stiff material; the consequence of this was that it was only possible to work neatly only section by section and only on level painting substrates, slightly annoying application marks occurring and the corner regions, in particular, representing problem areas. The further development according to the invention, on the other hand, permits rapid, easy and neat working, even on uneven painting substrates and in corner regions. For this purpose, the template 1 is to be designed, for once-only use, as a relatively long band (2) made of a compliant material with a self-adhesive underside 4, the underside 4 being protected with a peel-off film 5 before use. The band 2 advantageously has an absorbent top side 6. The band 2 is expediently made of wrinkle-free paper. The template according to the invention can be applied in advance wherever decorative elements are intended to appear and the paint application can be carried out subsequently without interruption. <IMAGE>

Patent DE-3644347-A1 (DE)
Title: Method for operating a light-emitting diode
Inventor: GRETHEN HARTMUT DIPL PHYS DR I
IPC: H05B44/00
Filed: 1986-12-19
Abstract: It is known for light-emitting diodes to be driven with a pulsed current consisting of rectangular waveform current pulses. The new method is intended to make possible to compensate for the drop in the radiation power of the light-emitting diode occurring during the pulse duration, because of heating. This is achieved in that the light-emitting diode (LED1...LEDn) has current pulses (I2) applied to it which rise with time over the pulse duration. The current pulse (I2) preferably initially rises suddenly to an initial value in order to rise linearly from there to a higher final value at the end of the pulse duration. The method is preferably used whenever a high radiation power yield is needed in the case of light-emitting diodes. <IMAGE>

Title: Safety fitting
Inventor: KROME HELMUT
IPC: B67D1/12
Filed: 1987-03-06
Abstract: A safety fitting for loading containers for liquids, such as beer or, if desired, wine, with gas, such as carbon dioxide or nitrogen, especially beer barrels, which is provided with a rupture disc, destruction of which causes the through-flow pipe of the safety fitting to be closed, the rupture disc being loaded by a perforating element which is subjected to the through-flow pressure of the gas, is to be designed in such a way that a reduction in the cross-section of the through-flow pipe cannot occur as the through-flow pressure increases. To achieve this, provision is made according to the invention for the through-flow pipe to be provided with a branch pipe, in which the perforating element and the rupture disc are arranged, the rupture disc closing off that end of the branch pipe which faces away from the through-flow pipe.
Patent DE-3708492-A1 (DE)
Title: Regulating device for a hydraulic system
Inventor: BLENDINGER HERBERT DIPL ING
IPC: F15B11/17
Filed: 1987-03-16
Abstract: For limiting the through-flow of a consumer, especially of a working piston having a one-sided piston rod, there is provided in the working-pressure line leading to the piston-side space of the cylinder an orifice gauge, the pressure difference of which loads a valve which makes a connection from a pump-adjusting means to the tank. Consequently, the feed quantity delivered by the pump is reduced, the through-flow is thus limited and too high an actuating speed of the consumer is avoided. By means of this device, the actuating speed of a working piston having a one-sided piston rod can be set equal or in a specific ratio in the two actuating directions, the control of the associated directional valve in each case being identical in the two actuating directions.

Title: Method of manufacturing a hollow body having a straight or oblique internal toothing
Inventor: DE MARCO FRANCO
IPC: B21H5/00
Filed: 1987-05-08
Abstract: In the rough method, a workpiece with an internal toothing is manufactured on an externally toothed mandrel. A more than marginal, large play (S), which is at least equal to the wall thickness (RW) of the blank, is in this case kept between the blank internal diameter (DI) of the workpiece (5) and the external diameter (DA) of the mandrel (4). In the same operation, the workpiece is reduced in cross-section from the blank dimension (cf. section 50) and at the same time the internal toothing (52) is shaped. The result is a better and more accurate shaping of the internal toothing with the same force expenditure. Moreover, the resulting wall-thickness increase leads to greater loadability of the product. <IMAGE>

Title: Continuously operating melt-filter system for coextrusion systems
Inventor: POHL HARALD
IPC: B29C48/03
Filed: 1987-05-19
Abstract: In blow moulding technology it is customary, if required, to filter the extruded melt before its entry into the blow-moulding head. This is necessary in particular when the virgin material has added to it a proportion of regrind which is produced from the plastic wastes occurring by the nature of the process, the regrind often containing impurities which it is absolutely necessary to keep back by means of a filter in order to avoid process malfunctions. The continuously operating melt-filter system contains a screen drum 6, into which a screen-gauze strip 11 is incorporated in an annular manner. The screen drum 6 intersects the flow channel 2 at a first point 16, as a result of which the melt stream is filtered, and, at a diametrically opposite point, intersects a flushing gap 4 connected to the flow channel, the partial melt stream guided therein freeing the screen drum from the picked-up dirt particles again. The system is not subject to throughput fluctuations or pressure fluctuations as a result of screen contamination, screen cleaning or screen exchange. No periodic maintenance or conversion work is necessary since the screen-gauze strip 11 is cleaned continuously (Fig. 1). <IMAGE>
