Patent DE-3300521-A1 (DE)
Title: Exhaust system for internal combustion engines
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1983-01-10
Abstract: The application with the title "Exhaust system for internal combustion engines" contains an exposition of the advantages which are obtained in the purification of exhaust gas by means of thermal reactors equipped with an ignition element. Whereas exhaust systems with a purely silencing function receive the entire flow energy of the exhaust gas throughput resulting from the explosion reactions in the engine combustion space and additional catalysers build up additional flow resistance, there is an additional source for the formation of flow energy in such thermal reactors due to the reactions triggered by means of ignition. This provides the possibility of either reducing the resistance of exhaust systems or of at the very least avoiding the necessity of increasing it for the purpose of purifying the exhaust gas, depending on the operating condition. This can only be achieved by means of a technologically correct revision of the entire system extending as far as the emergence of the exhaust gases into the atmosphere.

Title: Lens focusing device for a photographic instrument
Inventor: SPIES ECKHARD ING GRAD
IPC: G02B7/04
Filed: 1983-05-10
Abstract: A lens mount (2) is guided in a rotatable and displaceable fashion, and set rotating by a drive device. The lens mount (2) is pivoted by means of three distance elements (3) on jewel bearings on a fixed mounting plate (1) under spring preloading. Three equally long distance elements (3) are arranged symmetrically relative to the optical axis, and engage by means of tips (3a) in depressions (2a) of the lens mount (2) or of the mounting plate (1). Arranged parallel to the distance elements (3) are tension springs (4) whose points (2b) of application on the lens mount (2) and the mounting plate (1) are arranged on the same radii relative to the optical axis as the bearings (2a) of the lens mount (2) or of the mounting plate (1). The distance elements (3) and the tension springs (4) are of the same length. Upon rotation of the lens mount (2) the latter moves, supported by the distance elements (3), which assume a varying inclined position, into the arrow direction "C". The length of the tension springs is not altered in this process, so that the drive device is not required to apply any additional spring work. <IMAGE>
Patent DE-3319206-A1 (DE)
Title: Folding box with projecting edges
Inventor: BAERSCH ULRICH
IPC: B65D5/68
Filed: 1983-05-27
Abstract: The invention relates to a folding box with projecting edges, having a lid which is set back on its underside relative to its edge and has downwardly directed longitudinal and transverse walls, the upper side of said lid forming a uniform convex curvature. To achieve a simple constructional form with improved convex curvature of the lid, it is proposed that the longitudinal and transverse walls (1, 2) of the lid (l) are parts of a folding lid blank (Z) and the convex curvature of the upper side of the lid results from a fixed curvature tension. <IMAGE>

Title: Test instrument for contactlessly testing, particularly for testing the surface of continuous extruded material
Inventor: WOBODITSCH WALTER DR ING
IPC: G01N27/82
Filed: 1983-06-07
Abstract: The invention relates to a test instrument for contactlessly testing, particularly for testing the surface of continuous extruded material, preferably of compound Al/Cu conductors. It is the aim and the object of the invention to create a test instrument which can be produced without great technical expenditure with simple means, is insensitive to external influences and indicates errors even at the highest possible operating speeds. According to the invention, the object is achieved by the fact that a test probe, in which a probe inductance and a correction capacitance is arranged, is connected via a connecting cable to an oscillator following which in series a 90 DEG  phase shifter circuit is arranged, and the AFC output of the frequency demodulator is connected via an R-C section of large time constant, which is arranged in parallel, to the oscillator and is connected undelayed to a threshold IC which is arranged in parallel and subsequently to an evaluating unit, the probe inductance of the test probe forming a resonant circuit with the capacitance of the connecting cable and the capacitance of the capacitive voltage section including the correction capacitance. <IMAGE>

Patent DE-3324960-A1 (DE)
Title: Process for the preparation of water-thinnable binders carrying oxazolidine groups
Inventor: PAAR WILLIBALD DR
IPC: C08G18/67
Filed: 1983-07-11
Abstract: The invention relates to the preparation of water-thinnable binders which are obtained by reacting monoadducts of N-hydroxyoxazolidines with aromatic, cycloaliphatic and aliphatic diisocyanates with the hydroxyl groups of a polycondensation resin, polymerisation resin or polyaddition resin. The end product has an amine number of between 30 and 100 mg of KOH/g and is rendered water-thinnable by neutralising all or some of the amino groups by means of acids. The products are particularly suitable as binders for surface coatings (paints, lacquers, enamels) which can be deposited cathodically. Due to their composition, they release far fewer cleavage products during baking (stoving), significantly reducing corrosion in the ovens.
Patent DE-3327793-A1 (DE)
Title: Radar system
Inventor: MUELLER MANFRED ING GRAD
IPC: G01S7/34
Filed: 1983-08-02
Abstract: In a radar system having devices for time-dependent attenuation, in the interests of analog loads connected to the radar system the attenuation is kept lower in the very short range than corresponds to the R<-4> function, resulting in excess amplification in this distance range. In order to reduce the increased spurious target rate thereby produced, it is possible to prescribe an amplitude threshold for quantising the video signals within this range as a function of time and decreasing monotonically from the start of the range. Outside the very short range, the time-dependent attenuation is essentially proportional to R<-4>, and the amplitude threshold has a fixed value.
Patent DE-3329353-A1 (DE)
Title: Device for regulating the electrical voltage
Inventor: ANDROSOV NIKOLAI FEDOROVIC
IPC: H01F29/06
Filed: 1983-08-13
Abstract: The device for regulating the electrical voltage has an arc-shaped sliding track (3) which lies in a plane and with which a moving contact in the form of a roller (4) interacts. The roller (4) is designed as a truncated cone. The smaller base area (11) of the roller (4) is directed towards the geometrical centre of the arc-shaped sliding track (3). Since the ends of the truncated-conical roller (4) have the same angular velocities, it is ensured that they wear uniformly. <IMAGE>
Patent DE-3340843-A1 (DE)
Inventor: OESTERLE HERMANN FRIEDRICH DIP
IPC: G01P13/04
Filed: 1983-11-11
Abstract: An electromechanical pulse generator includes a toothed disk driven by a rotating shaft to operate two pairs of contacts to generate one pulse output and one direction-of-rotation output. The pulse contacts and the direction-of-rotation contacts operate independently of each other. The toothed disk is rotatable and axially displaceable. The axial displacement is dependent on the direction of rotation via an inclined plane in the form of a screw thread which is rotatable by the rotary shaft. By axial displacement of the toothed disk, the direction of rotation of the shaft is detected, and by rotation of the toothed disk, the pulses are generated.

Title: Method of processing synthesis gases
Inventor: SCHRAMM WALTER
IPC: F01K25/14
Filed: 1983-12-13
Abstract: Hot synthesis gases generated at a pressure of more than 40 bar are processed by cooling, purification, and if necessary, shift conversion of carbon monoxide. Crude synthesis gas is fed at a high temperature to an expansion turbine and let down with production of work to a lower pressure at which the processing takes place. The processed synthesis gas is recompressed, the energy required for the compression being at least in part provided by the expansion turbine.
Patent DE-3400511-A1 (DE)
Title: Printing device for a typewriter or similar office machine having a daisywheel
Inventor: KITTEL ARTHUR ING GRAD
IPC: B41J1/24
Filed: 1984-01-10
Abstract: When frequently changing to other types of lettering or foreign characters, it is necessary for the daisywheel 7 to be able to be exchanged very easily and without special skills by the person operating the machine. For this purpose, it is known to pivot a pivot bearing with the motor and a drive shaft from the operating position into an exchange position provided for exchanging the daisywheel. In small typewriters with restricted space, the pivot bearing cannot be pivoted far enough for convenient exchange of the daisywheel 7 to be possible. In this case, the operator still has to apply a certain amount of skill. The invention is based on the object of simplifying the daisywheel exchange. This object is achieved in that the carrier (17) with the rotary adjustment shaft (6) and the daisywheel (7) is arranged so that it can be inserted into a receiving device (18) or withdrawn therefrom, and in that the rotary adjusting shaft (6) has a coupling half which, when the carrier (17) is inserted or when it is withdrawn can be automatically coupled to or uncoupled from the coupling half of a motor (51). The great advantage consists in the fact that the daisywheel (7) can be exchanged outside the machine. The ink ribbon cartridge (16) does not have to be removed from the slide (3) either. By omission of the pivot bearings of known arrangements, a space-saving construction is achieved which ... Original abstract incomplete. <IMAGE>

Patent DE-3410846-A1 (DE)
Title: Push-button switch
Inventor: AICH WERNER
IPC: H01H13/06
Filed: 1984-03-23
Abstract: The push-button switch has an elastically deformable snap part (2) and a support (1) which enclose a contact chamber (3) in whose interior a contact pair is arranged whose contacts (6, 16) are electrically connected to one another when the operating button (11) is pushed down. The contact chamber (3) is connected via a channel (14) to the cavity (12) which is formed by the operating button (11), the snap part (2) and a guide (8) and, for its part, is connected to the outside atmosphere via an air gap (22) between the guide (8) and the operating button (11). The connection which thus exists for the purpose of pressure equalisation between the contact chamber (3) and the outside atmosphere is not direct, so that it is made more difficult for contamination to penetrate into the contact chamber (3). A further improvement of the intended labyrinth effect for contamination penetrating into the push-button switch is achieved in that the connection between the channel (14) and the cavity (12) is passed via slots (19; 20) which are offset with respect to one another. <IMAGE>

Title: Work head for labelling workpieces
Inventor: BAUBLYS SAULIUS DIPL ING
IPC: B44B7/00
Filed: 1984-06-23
Abstract: A work head (11) for labelling workpieces (12) is described, in which a character (13) has to be written by an activatable tool (23) by relative movement between the work head (11) and the workpiece (12). In order to be able to carry out the labelling of the workpieces (12) with a plurality of characters (13) considerably more quickly and, in doing so, not to have to multiply correspondingly either the control expenditure or the constructional expenditure in terms of tools (23), the work head (11) is provided with a plurality of tools (23) which are arranged at a fixed distance from one another and can be activated individually and independently of one another. In this case, the relative movement between the work head (11) and the workpiece (12) is determined by the 7-segment illustration of the character to be written. <IMAGE>

Title: Process for drying and preheating bulk solids, such as coking coal, and fluidised-bed dryer for carrying out the process
Inventor: LORENZ KURT DR
IPC: B01J8/36
Filed: 1984-07-07
Abstract: The invention relates to a process for drying and preheating bulk solids, such as coking coal, having a wide particle size range by means of hot gaseous or vaporous media, the heat transfer in a fluidised bed being effected directly by hot fluidising gases and indirectly by heat exchanger surfaces, and the bulk solids being fluidised by the hot fluidising gases and kept in suspension. According to the invention, the coarser particle fractions, which are no longer kept in suspension and which collect below the heat exchanger surfaces, are to be conveyed mechanically towards the hot part of the fluidised bed. To carry out this process, a fluidised-bed dryer having particular conveying members above the sieve plate-like inlet face for injecting the hot fluidising gas is proposed. <IMAGE>

The pincers (4) take hold of the containers (1) from above by the container head (1.2), are mounted on the conveying means (2) to be pivotable about axes (8) extending in the conveying direction of the latter and are guided on a guide rail (9) which determines the pivoting angle (13) of the pincers (4), extends along the conveying means (2) through the observation field and can be displaced and adjusted to modify the pivoting angle (13) in relation to the pivoting axes (8) of the pincers (4). <IMAGE>
Patent DE-3428677-A1 (DE)
Title: Device for measuring deposits
Inventor: HERSCH RUDOLF
IPC: E21B47/06
Filed: 1984-08-03
Abstract: The present invention relates to a device for measuring deposits, having a probe-like housing in which there are mounted sensors for physical measured quantities. Such measurements are carried out in boreholes during oil exploration. However, the prior art encounters problems with such measurements and delivers only inaccurate results, since the pump drive unfavourably affects the determination of the measured value. The present invention provides a remedy here by mounting the probe-like measuring housing no longer above the pump but below the submersible pump, in particular of the motor, so that the static and dynamic conditions of the deposits can be precisely detected.
Patent DE-3430047-A1 (DE)
Inventor: SIJSLING PETER
IPC: B02C19/08
Filed: 1984-08-16
Abstract: The problem of pestle-type grinders, in particular for laboratory use, which are fitted with a container for receiving the grinding material in which a pestle is movably arranged as a grinding element, and with a drive system for the pestle, is essentially that, because the pestle is held and guided during the grinding process on a holding device which extends through the cover of the grinding container, it is impossible to have a fully closed system. To solve this problem it is envisaged that, while the grinding container (17) remains stationary, the drive force is transmitted to the pestle (20) in a magnetic manner.
