Title: Thread-gripping device for weft insertion on weaving machines
Inventor: KAISER STEFFEN
IPC: D03D47/20
Filed: 1986-04-11
Abstract: Thread-gripping device for weft insertion on weaving machines, especially on double-shed weaving machines. The aim of the invention is a thread-gripping device, by means of which, above all, work productivity is to be increased. The object of the invention is achieved in that there are arranged thread-guide edges having regions which are at the same distance as or a greater distance than curved guide plates from the bottom wall of the thread-gripping device, and in that there is arranged parallel to the bottom wall a tip adjustable relative to the latter and having thread-guide edges. The movable tip is preferably adjustable about a centre of rotation and its thread-guide edges project beyond the width of the bottom wall on both sides. Advantageously, division marks are arranged on the adjustable tip and a fixed point is located on the bottom wall. Furthermore, curved guide plates, having a longitudinal slot leaving the profile of the basic body open and widening in the weft direction, are arranged. Preferably, one thread-guide edge projects beyond the curved guide plates. This is assigned to the tip of the guide plates which is set back in the weft direction. Advantages are in a symmetrical and mirror-image arrangement of the thread-gripping device in relation to the middle shed. The invention is used especially on double-shed weaving machines having rod grippers or band grippers for weft insertion.

Title: Device and process for metal pulse arc welding
Inventor: STRUMPF HANS-GUENTER DIPL ING
IPC: B23K9/09
Filed: 1986-07-26
Abstract: A device for metal pulse arc welding contains a power supply unit by means of which current can be supplied to a melting electrode. In fixed-cycle operation a higher pulse current or a higher pulse voltage can be generated during pulse phases and a lower base current or base voltage can be generated during base phases. With a low switching expenditure it should be possible to realise high pulse frequencies and, if necessary, short pulse phases, whereby high regulation dynamics should be provided. It is proposed that a first switching converter (8) be provided, by means of which the higher pulse current (IP) or the higher pulse voltage can be generated only during the respective pulse phase. The first switching converter (8) has a generator (28) connected in parallel with it, by means of which at least during the base phase the essentially constant base current (IG) or the base voltage can be generated, whereby the first switching converter is switched off during the base phase. <IMAGE>

Patent DE-3637700-A1 (DE)
Inventor: ROTH PAUL DIPL ING
IPC: B01D53/26
Filed: 1986-11-05
Abstract: A process for regenerating a moisture charged drying cartridge and apparatus for carrying out the process. Drying cartridges are used to prepare drying air for drying synthetic plastics in the form of granulates or powders. Used drying air, which has become charged with moisture, is passed through a drying cartridge which takes up the moisture from the drying air. The dried drying air can then be passed again through the material to be dried. In regenerating a spent, moisute laden drying cartridge, external air is collected, heated and exhausted after passage through the cartridge, which subsequently must be cooled. In order to achieve the lowest possible dew point after regeneration of a cartridge to be dried with a minimum consumption of energy, the regeneration air is passed in a closed regeneration circuit (11) through the cartridge (9'). The drying cartridge (9) lies in a drying circuit which includes a chamber (1) for the material to be dried, and it can be switched into a regeneration line (12) which forms a portion of the closed regeneration circuit (11). With this process and apparatus the moisture in the cartridge (9') can be expelled substantially without any energy loss.

Title: Light-triggered thyristor
Inventor: MITZKUS WERNER
IPC: G02B6/42
Filed: 1987-02-26
Abstract: Light-triggered thyristors are known which have a window in the cylindrical insulating sheath. A flexible optical fibre is adjacent to this window on the outside and a rigid light deflector which guides the light onto the photosensitive area of the semiconductor wafer is adjacent to it on the inside. The novel light-triggered thyristor is intended to reduce the transmission losses due to the multiplicity of optical interfaces. For this purpose, the flexible optical fibre (5) is mounted in a rigid sheath (4) which fits gastightly into an opening (14) in the cylindrical insulating sheath (10). The flexible optical fibre (5) is directly adjacent to the rigid light deflector (1) and the rigid sleeve (4) is gastightly joined to the rigid light deflector (1). <IMAGE>

Title: Method for recycling precipitator dusts
Inventor: SCHAEFER KLAUS DIPL ING
IPC: C21C5/28
Filed: 1987-03-18
Abstract: The precipitator dusts which arise in large quantities in steel manufacture and which are separated off in precipitator installations, have a high iron content and should therefore be recycled to steel manufacture. Since these dusts tend to form lumps because of their fine grain size, they are blown by a carrier gas into the metallurgical vessel, namely with the aid of nozzles arranged in the bottom of the vessel. Preferably, they are blown in through the same nozzles through which carbon carriers are also blown into the vessel.

Patent DE-3712828-A1 (DE)
Inventor: MEIXNER FRANZ
IPC: B29C45/18
Filed: 1987-04-15
Abstract: When filling injection-moulding units with non-freeflowing or viscous materials, such as for example glass fibre charged polyester material, screws do not draw in such materials unassisted. In order to permit such materials to be fed continuously to a conveying screw (6) via a feed throat (15), the feed throat (15) is designed as a rotational body having a casing (14) which can rotate about an axis (A) of rotation, the conveying screw (6) being taken through the rotational body in the region of the inner surface of the casing. It is achieved by the invention that the starting material introduced into the feed throat (15) is constantly taken along, due to the static friction between the rotating casing (14) and the conveying screw (6), and consequently material is continuously fed to the conveying screw (6). <IMAGE>

Title: Closing device for a liquid-filled container
Inventor: STOICHER MAX
IPC: A01C23/00
Filed: 1987-04-29
Abstract: The closing device for liquid-filled containers is used, in particular to ensure that liquid-manure tanks can be filled completely. A liquid manure tank of this kind, which operates, by suction and pressure, has a closing device which is arranged above and partially outside the liquid manure tank and has an upper connection for a compressor, this connection opening into a valve-seat tube, the lower outlet of which forms an upper valve seat for a float ball which floats in the liquid, at least in the final stage of filling the liquid manure tank. To allow the liquid manure tank to be filled completely, even with foaming liquid, it is envisaged that a forced air flow directed at the liquid and at the float ball be generated all around the upper valve seat of the valve-seat tube. This avoids the formation of bubbles in the region of the float ball. These would raise the float ball and press it against the upper valve seat prematurely.

Title: Manually actuable toy sand dredger
Inventor: KRANE VOLKER
IPC: A63H33/32
Filed: 1987-06-24
Abstract: The invention relates to a manually actuable toy sand dredger having a pivotable extension arm and two levers for raising and lowering the extension arm and for actuating a dipper shovel. A design which is used in kindergarten sandpits, for example, uses a four-bar mechanism as an extension arm, the web of which is mounted on one side and is connected to the lever to permit movement of the extension arm. The other lever is fastened to a crank which acts via a connecting rod on a rocker, to the extension of which there is fastened the dipper shovel. In addition to the danger of dirt collecting in the joints, there is also a danger that children playing with this toy will be injured, as the set of rods of the four-bar mechanism and/or the dipper shovel come so close to one another that there are points where catching or cutting may occur. According to the invention this danger is to be eliminated by means of a rigid extension arm which accommodates at least two pulleys or pinions in bearing blocks. A lever is fastened to the extension arm. The other lever is connected to a pulley or a pinion, the movements of which are transmitted via a belt or chain drive to the other pinion and from thence via a lever to the dipper shovel. The whole drive can be protected very well in this manner. Limiting the stroke can reliably eliminate the danger of catching or cutting.

Title: Means and process for manufacturing biosensors on the basis of an oscillating quartz crystal, and use thereof for determining antigens and affinity ligands
Inventor: MUELLER-SCHULTE DETLEF DIPL CH
IPC: G01N27/00
Filed: 1987-10-08
Abstract: Means and process for applying a thin plastic film onto a piezoelectric oscillating quartz crystal by means of a polymer insoluble in an aqueous medium are described. Coating is effected either from an organic solution or with the aid of a vinyl monomer plasma. Owing to the polymer coating, antibodies or biomolecules can be bound either adsorptively or covalently. These immobilised biomolecules can then bind antigens or ligands; the resulting increase in mass of the oscillating quartz crystal can be measured quantitatively in the ng range on the basis of the change in oscillation frequency. Immunoassays and the determination of ligands for affinity chromatography are thus made possible.
