Patent DE-3312687-A1 (DE)
Inventor: WELZHOFER KLAUS
IPC: G01R31/28
Filed: 1983-04-08
Abstract: For the purpose of testing units which contain electrical circuits, an interpretation circuit and a load circuit are connected to the output of the unit being tested by way of a line. A load circuit is provided which contains two constant current sources which are respectively variable in terms of current value and which are respectively connectible and disconnectible. The one constant current source therefore serves as a load current source and the three serves as a load current sink. A determination can be made, with the assistance of a variable control voltage, as to whether the load circuit operates as a current source or a current sink. The constant current source and the variable control voltage are connected to one another and to the line to the unit being tested by way of a diode bridge. A comparator circuit is connected to the same line and comprises an impedance and voltage level converter and two comparators. Separately variable reference voltages are supplied to the comparators. Three voltage ranges are thereby formed for the evaluation of the output signal of the unit being tested. The samping time of the evaluation is defined by sampling signals. The interpretation circuit and the load circuit are programmable within broad current and voltage ranges so that they can be employed to test units which belong to different circuit technologies.

Title: Process and equipment for very largely slag-free tapping of molten metals, in particular molten steel, from metallurgical vessels
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: C21C5/46
Filed: 1983-07-30
Abstract: In the process indicated, the slag floating on the molten baths in the case of a relatively high level of the molten baths towards the end of tapping sinks to the pouring orifice in the vessel bottom, which can be closed or controlled by means of a slider seal or flap seal. In order to avoid dispersion of slag, caused by metal streams, towards the end of the tapping process, so that slag-free molten metal can still be tapped until just before the closing position is reached, that is to say in order to obtain a recovery of more than 95% of molten metal, it is proposed that a flow body (11), fixed to a lifting device (7) in vertical alignment with the tapping orifice (13) of the slide seal or flap seal (2), is held in a position in the upper part of the melt (3), that, when a residual quantity of molten metal (3) with a critical level of the molten bath of 200-500 mm above the upper edge of the tapping orifice of the open slide seal or flap seal (2) is reached, the flow body (11) is lowered into a lower position about 30 to 50 mm above the base (1c) of the vessel bottom and that the outflow of the melt is stopped when the level of the molten bath sinks down to the base (1c) of the vessel bottom. <IMAGE>

Title: Cut-off tool holder for trapezoidal, narrow cut-off tools on single-spindle automatic lathes
Inventor: HUPFER GUENTER
IPC: B23B29/04
Filed: 1983-08-10
Abstract: The invention can be used in the cutting process during turning and cutting off. The aim of the invention is to mount prefabricated, trapezoidal cut-off tools for use on single-spindle automatic lathes while taking into account the space conditions at an automatic lathe of this type. The achievement of this object is important for the economical use of bright bar steel, because the conventional cutting-off widths can consequently be reduced by 30-40%. Compared with the previous mounting of square or rectangular blanks, prefabricated, trapezoidal, narrow cut-off tools can be used with this tool holder, the profile of which cut-off tools corresponds to the cut-off tool edge over the entire length. The cut-off tool according to the invention can be used on all single-spindle automatic lathes of the most varied types. Depending on the machine type, only the bottom part and the fastening holes made there have to be adapted to the cut-off slide. <IMAGE>

Title: Process for the preparation of red phosphorous low in iron
Inventor: LEHR KLAUS DIPL CHEM DR
IPC: C01B25/023
Filed: 1983-11-25
Abstract: To prepare red phosphorous low in iron, molten yellow phosphorous is first converted into red phosphorous in a ball mill at temperatures from 280 to 590 DEG C. After cooling, the red phosphorous in the ball mill is covered with water and subjected to wet milling. The aqueous suspension of red phosphorous with a residual friction of yellow phosphorous withdrawn from the ball mill is heated, while stirring, to 40 to 80 DEG C, and at least one organic complexing agent is added which is suitable for bringing polyvalent metals into solution, and for keeping them in solution. Aqueous alkali metal hydroxide is then added to the suspension, setting a pH of at least 10, and the residual fraction of yellow phosphorous is destroyed with the formation of phosphine. Finally, the cooled aqueous suspension is filtered and the red phosphorous is dried.

Title: Method and apparatus for the calibrating reduction of the cross-sectional area of a workpiece rotating during the reduction
Inventor: GROB ERNST
IPC: B21H1/20
Filed: 1984-01-05
Abstract: In rotatingly driven rolling heads (4), there are rotatably mounted rollers (5) which revolve in the manner of planets as the rolling heads revolve and exert a hammering action on the workpiece (W) in such a way that, as the diameter is reduced, material is displaced principally in the direction of the axis (A) of the workpiece. During this process, the workpiece is at least rotated (this is, for example, sufficient for necking down) and, in general, is also moved along the axis (W) of the workpiece. The rolling heads can be adjusted in and out for necking or other changes in diameter. <IMAGE>

Title: Method and arrangement for deriving a control signal for a phase-locked loop
Inventor: EHRLICH WOLFGANG DIPL ING
IPC: H04L7/00
Filed: 1984-03-08
Abstract: The invention relates to a method and circuit arrangement for deriving a control signal for a phase-locked loop which is used for clock recovery of a broadband, virtually square-wave-shaped transmission signal. The object of identifying the time of required zero passages in the transition of a ternary signal from plus to minus and vice versa and of ignoring zero passages from a different origin is achieved by producing a hysteresis-shaped transmission characteristic with the aid of the thresholds of a threshold value discriminator and downstream bistable trigger circuits. Furthermore, the required zero passages are separated from the unwanted zero passages with a subsequent time window logic comprising monostable trigger stages. <IMAGE>

Title: Ink-ribbon device for bidirectional printing in typewriters or similar office machines
Inventor: BEHRENS HERBERT
IPC: B41J33/38
Filed: 1984-09-06
Abstract: To achieve a high printing speed, in known series printers, printing continues even during the return movement of the print head into the position at the beginning of the line. The invention is based on the object of making such bidirectional printing possible even in thermal printers, in which the ink ribbon (11) remains unchanged during the printing movement of the print head relative to the recording medium (1), and a supply spool (16) in the cartridge (12) feeds the ink ribbon (11) and a winding spool (17) takes up the ink ribbon (11) to the same extent as the ink ribbon (11) is moved with the print head (9) relative to the carriage (3). This object is achieved in that the ink ribbon (11), which can be driven by a drive device, is fed through the holder (13) with two sections (18, 19) running one above the other and in opposite directions to one another, in that the holder (13) is arranged so as to be vertically adjustable by means of a reversing device arranged on the carriage (3) to set one of the two sections (18, 19) in the operating position relative to the print head (9), and in that the ink ribbon (11) is unwound from the supply spool (16) and wound onto the winding spool (17) at a speed which corresponds to the carriage movement. As a result, bidirectional printing is achieved in a simple manner with optimum utilisation of the ink ribbon. <IMAGE>
