Title: Precision turning method for disc-shaped workpieces
Inventor: LENHART ARMIN DR
IPC: B23B1/00
Filed: 1987-07-24
Abstract: Precision turning method for disc-shaped workpieces (2) with uneven flat sides (24, 27). To machine the workpiece (2) by turning, the workpiece (2) is radially clamped during a first machining step and accommodated by a plane bearing surface (6) of a work spindle (4). According to the invention, a liquid (10) acting as a supporting bed is located, during turning in the intermediate spaces (62), resulting through unevenness, between the bearing surface (6) and the flat side (27) facing it. Effective levelling of the flat side (24) is achieved by this measure. In the second turning step, the opposite flat side (27) can then be smoothed as well as levelled by known methods.

Title: Device for the conveying and registration of sheets
Inventor: HILTMANN GERD
IPC: B65H9/16
Filed: 1987-07-25
Abstract: The device for the conveying and registration of sheets of paper, cardboard or the like is used on a conveying and registration table. Devices are known having a guide rule and a narrow conveyor belt circulating slightly obliquely with respect to the guide rule. In this arrangement, the sheets are either loaded by balls or sucked by a vacuum. If the adhesion of the sheet to the conveyor belt is too high, satisfactory conveying and registration of the sheets are impaired. The object of the invention is to design the device such that the sheets are guided with optimum pressure on the conveyor belt. The object is achieved in that suction openings are arranged adjacent to a conveying element (6) or between a plurality of conveying elements (6), in a metal guide plate (1) for the conveying elements (6) which project entirely or partly above the surface of the metal guide plate (1) and circulate slightly obliquely with respect to the guide rule (2), which suction openings open into a suction channel (4) which extends below the entire conveying device and is connected to the suction side of a side-channel fan. <IMAGE>

Title: Apparatus for converting volatile materials dissolved in water into the gas phase for the purpose of analysis using a gas chromatographic method
Inventor: FUELLING RAINER DR
IPC: G01N30/12
Filed: 1987-09-07
Abstract: The invention relates to an apparatus for converting volatile materials dissolved in water into the gas phase for the purpose of analysis using a gas chromatographic method. Known methods cannot be automated or cannot be applied to certain groups of materials. Taking into account increased environmental awareness and contamination of bodies of water observed more frequently in recent times, it is an object of the invention to make possible the automatic measurement of contaminants (impurities) with simultaneously high sensitivity of the method. This object is achieved by a narrow column comprising inert material, which column is filled with column packing. Water continuously flows through the column, while a carrier gas (nitrogen) is passed through the column in the countercurrent mode. The gas stream can then be fed to known apparatus such as cooling apparatus (cold traps), preliminary columns or the like and finally fed to a gas chromatograph. This can in each case be carried out automatically so that there are only a few minutes between the appearance of a contaminant and the availability of a measurement result.

Abstract: A partly single-stranded and partly double-stranded nucleic acid probe containing a transverse-crosslinking compound covalently bonded to its double-strand region has a chelating agent for metallic ions bonded to the nucleic acid probe by a functional group of the transverse-crosslinking compound. This nucleic acid probe is useful for detecting nucleic acids by hybridization with formation of a hybrid double strand. Following successful hybridization, a solution of fluorogenic metallic ions is added, and after removal of the metallic ion solution and washing, the bonded metallic ions are extracted by means of a reinforcing solution. The hybrid double strand so formed is detected by the fluorescence of the metallic ions in the reinforcing solution.

Title: Process for producing hard and wear-resistant surface layers
Inventor: BERGMANN HANS WILHELM PROF DR
IPC: C23C4/06
Filed: 1988-03-12
Abstract: Eutectic iron-titanium alloys were smelted in an arc furnace and then ground to give powders of a sprayable grain size of 45-93  mu m. Cast iron and steel substrates were coated with this powder by low-pressure plasma-spraying. During a subsequent remelting with a CO2 laser, the sintered materials TiN and TiC were formed in the melting bath, which was additionally top-blown with a reaction gas (N2). By means of these sintered materials, a surface hardness of 1000-1100 HV was achievable in a surface layer of 0.5-0.8 mm thickness. Applications and the transferability of such inexpensive sintered material coatings are discussed.

Title: Device for erecting a packaging blank
Inventor: JENSEN POUL NEDERGAARD
IPC: B31B50/99
Filed: 1988-06-04
Abstract: A packaging blank, which has a plane, mainly polygonal bottom zone (21) and has side-wall zones (22-24) which are connected to the bottom zone (21) by folding lines along the edges of the bottom zone (21), can be erected by means of an erection device. This device has a supporting surface (19), along the side edges of which are rotatably mounted rollers (14, 15, 17) which serve for bending or erecting the side-wall zones (22-24) when the bottom zone (21) of the blank is pressed against the supporting surface (19) of the device. Because rollers (14, 15, 17) are used, instead of the conventional fixed guide plates, for erecting the side-wall zones (22-24) of the blank, this ensures that the force necessary for pressing the bottom zone (21) of the blank against the supporting surface (19) is reduced, and that a sliding movement between the rollers and the side-wall zones is also avoided. <IMAGE>

Title: Female-type spring part of a snap fastener closure
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B17/00
Filed: 1988-06-22
Abstract: In a female-type spring part of a snap fastener closure of a moulded sheet-metal element, on the one hand a pot and, on the other hand, a flange connected to the pot are used, the pot also having a pot bottom opening in addition to a radial groove for receiving an annular spring. The flange serves for bearing against a carrier serving to attach the spring part. For easier and more efficient production, it is proposed to form the pot and the flange integrally from a common sheet-metal blank which is folded back in some regions and, in this process, to produce a double-layer annular zone by the folding-back. In this case, the folding-back edge determines the clear width of the one pot opening from which the two folded limbs start, of which the one folded limb extends up to the other pot opening.

Title: Thermoforming press having an inherently drivable electronically controlled insertion and/or removal device for parts to be pressed or pressed parts
Inventor: SIEGERT KLAUS DR ING
IPC: B21D43/10
Filed: 1988-07-30
Abstract: The invention relates to a thermoforming press having an inherently drivable, electronically controlled insertion and/or removal device for pressed parts or parts to be pressed. The sequence of movement of such insertion and/or removal devices are synchronised in a controlled fashion with the pressing cycle by means of appropriate sensors. In order to ensure that the insertion arm does not enter the pressing tool while the latter is being closed in the event of synchronisation malfunctions, which would cause destruction of the tool, the arm of the insertion device is provided with a device-side stop which is assigned to the said arm in a stationary fashion; the press, for its part, is also provided with a press-side stop which is guided in a displaceable fashion and is arranged in the region of movement of the device-side stop. The press-side stop is forcibly connected to the press slide, to the movable pulling and holding-down slide on the holding-down slide during pressing or to the drive, for example the crankshaft of the press, and is driven from or by the said drive. The stops are matched to one another and to the machine parts assigned to them in such a way that it is possible to use the press-side stop mechanically to preset a maximum proximity, which is variable in dependence on the stroke, of the insertion arm to the pressing tool; the said maximum proximity does not give rise to a risk of the arm colliding with the tool. If there is mutual contact between the aforementioned stops, the drive of the device-side stop [lacuna] by the insertion of ... Original abstract incomplete.

Title: Electric amplifier for actuating valves
Inventor: HESSDOERFER KARL
IPC: H05K1/18
Filed: 1988-11-11
Abstract: Amplifiers for actuating valves, in particular proportional valves, are made up of a series of components, namely an output stage, a mains component, drive electronics, if appropriate a controller and corresponding inputs for set values and actual values. In the drive electronics, the desired control and output characteristic is produced in accordance with valve type. According to the invention, the drive electronics are replaced by a programmable component with read-only memory in which the amplifier is assigned to a specific valve type by the read-only memory being loaded with the valve-specific data of this valve type. Thus, unprogrammed amplifiers which are identical with one another can be produced and stocked. If required, an amplifier of this kind can be loaded with the required program and is thus assigned to a specific valve.

Title: Magnetic buffer and stirrup coupling for model railways, and also magnetic decoupling
Inventor: NEUHAUS PETER
IPC: A63H19/18
Filed: 1989-01-27
Abstract: A coupling of this kind, with movable buffer parts and stationary stirrups, was not found in specialist journals or at a show. Likewise, no magnetic coupling using soft-iron parts for coupling, which are magnetised from the vehicle, as a result of which too early an approaching of the vehicles is to a large extent avoided. Likewise, no magnetic field decoupling and buffer beam train division was found, which can be varied in its polarity and magnetic force or is connected to a shunter model. Only an older patent was found in which semi-rounded permanent magnets on wooden toy railways, screwed in immovably, are used as couplings. By changing the pole, two vehicle groups can be obtained which can be rotated and turned with respect to each other in their respective group and which always push on the buffer parts at opposite polarity and are thus coupled. However, the first vehicle group is never coupled to vehicles of the second group. <IMAGE>
