Title: Process and device for filling straight hollow-profile members for spacer frames in insulating glass panes with a granular desiccant
Inventor: BOGNER UWE
IPC: E06B3/673
Filed: 1987-03-31
Abstract: A process for filling straight hollow-profile members (7) for spacer frames in insulating glass panes with a granular desiccant is described. The hollow-profile members (7) are closed at one of their ends (7b) such that no desiccant can emerge there. At the opposite end (7a), the desiccant is introduced into the hollow-profile member (7) with the assistance of a propellent gas (compressed air). It is ensured that the propellent gas can only emerge at the closed end (7b) or in a section, contiguous therewith, of the hollow-profile member (7) through holes (19) which are so small that the desiccant particles are held back in the hollow-profile member (7). <IMAGE>

Title: Method for checking the operability of a test device for high-voltage conductors and test device
Inventor: BRUEGGEMANN GISBERT DIPL ING
IPC: G01R35/00
Filed: 1987-04-15
Abstract: The invention relates to a method for checking the operability of a test device for determining the freedom from voltage of an electrical conductor, particularly of a high-voltage or medium-voltage conductor. In addition, the invention relates to a corresponding test device. Whilst it has previously been impossible to check the indicator of corresponding test devices for it operability, the invention now proposes for the first time that the measuring electrode including the feedline to the indicator also be checked by using a test electrode in the vicinity of the measuring electrode to which a low-voltage high-frequency signal for testing is applied via a corresponding line. The measuring electrode responds to this signal and thus the capacitance function of the measuring electrode and the line function of the feedline can be checked independently of whether the checked conductor is carrying current.

Title: Circuit arrangement for switching PCM channels
Inventor: GRASSMANN WOLFGANG DIPL ING
IPC: H04Q11/08
Filed: 1987-06-23
Abstract: The invention relates to a circuit arrangement for switching PCM channels in base band, the serial data to be switched and arriving an n input ports being parallel-converted block by block, temporarily stored in a memory and, after read-out, again being supplied serialised to n output ports which are in each case allocated to one or more destination addresses, and is characterised by the fact that a first temporary storage of the parallel-converter data blocks occurs in n input registers R allocated to the n input ports, that then a second temporary storage occurs in a RAM memory in such a manner that the data blocks are written in successively in accordance with their input order under a memory address which is sequentially incremented (incrementing), and that the data blocks are read out as determined by the number of the output port or the time slot contained in the destination address or allocated to the destination address and are again temporarily stored in an output register R which are in each case allocated to the n output ports (Figure 1). <IMAGE>
Patent DE-3722030-A1 (DE)
Title: Plastic plain bearing
Inventor: FUCHS FRANZ DIPL ING
IPC: F16C33/74
Filed: 1987-07-03
Abstract: The two sliding rings of a known plastic plain bearing are secured axially because a ring-shaped extension, which is formed on the inner flexible sliding ring, locks in a groove in the outer sliding ring when the two rings are pushed into one another. This locking engagement increases bearing friction. At the other axial end of the bearing, the sliding surfaces are exposed and in danger of contamination. For use, the assembled bearing must also be secured on a retainer (shaft or the like). Because of the plain bearing design consisting of a sleeve and a shaft, the plain bearing is serviceable without further assembly. At least one exposed blade is arranged on the shaft on both sides of the sliding face and formed with a greater diameter than this sliding face, which blade projects into recesses which are formed in the sleeve on both sides of its sliding face and which are open at their ends. When the two bearing components are pushed into one another, the blade can be subjected to elastic deformation, and finally the blades form a low-friction axial mounting for the bearing components and seal the bearing at both ends. Plastic plain bearing, particularly for use in a contaminated environment.

Title: Connecting anchor for a two-leaf masonry structure
Inventor: MICHEL HANS
IPC: E04B1/76
Filed: 1987-09-18
Abstract: The connecting anchor for the leaves (1, 2) of a two-leaf masonry structure comprises two releasably connected parts (10, 20). In order, when there is a defined spacing between the masonry-wall leaves, to permit unobstructed relative displacement, in particular in the vertical direction (different heat expansions, settling, shrinkage, etc.), one anchor part (10) exhibits an eyelet (11) which slidingly encloses a vertical web (21) on the other anchor part (20). The latter is anchored in the masonry structure by means of arms (22, 24) which extend from the two web ends and each form an anchor bow (23, 25) in mutually perpendicular planes. The eyelet part (10) may likewise exhibit an anchor bow (13) or (in a variant) a screw thread for an anchor dowel. The two parts (10, 20) are preferably produced as bent parts, using round wire. By virtue of the movable eyelet/web connection, the conduction of heat via the connecting anchor is also virtually stopped. <IMAGE>

Title: Oil-superimposed discharge valve for rotating vacuum pumps
Inventor: ZWETKOW ZWETKO
IPC: F04C29/00
Filed: 1987-11-07
Abstract: The invention concerns a discharge valve for rotating vacuum pumps. This implements three valve functions: the previous function of discharging gas or air, and pressure-dependent oil feed and draining as additional new functions. It consists of a valve chamber, a piston moving in this with valve seat in its bottom, a stopper, compression springs and support elements. In the wall of the valve chamber there is at least one aperture close to the bottom, and two apertures in the middle section. Of these two apertures, one is connected to the pump's suction chamber via an oil line. The outer wall of the piston has a ring groove, whose distance to the bottom edge of the piston is selected so that together with the piston stroke, it corresponds to the distance of the two apertures from the bottom of the valve chamber. The one compression spring is located between the stopper and a support element in the piston, while the other compression spring stretches from this support element to a support element near the upper edge of the valve chamber.

Title: Integrated circuit with "latch-up" protective circuit in complementary MOS circuit technology
Inventor: RECZEK WERNER DIPL ING
IPC: H01L27/092
Filed: 1987-12-23
Abstract: By means of the incorporation of non-linear elements between earth (VSS) and the p-conducting semiconductor substrate (Psub) and between the supply voltage (VDD) and the n-conducting semiconductor zone (NW), the risk of occurrence of the "latch-up" effect, triggered by the build-up of base charges on the parasitic vertical and lateral bipolar transistors, is reduced. The space requirement for the additional non-linear elements to be incorporated is small and the circuit properties of the MOS transistors are not hereby influenced. Realisation of the non-linear elements can be achieved by means of Schottky contacts or by means of additional MOS transistors, which are interconnected as diode elements. <IMAGE>

Patent DE-3805536-A1 (DE)
Inventor: LENZ ROLF
IPC: C05F11/00
Filed: 1988-02-23
Abstract: The organic-mineral fertiliser according to the invention is characterised by a combination which consists of a mixture of 92 % by weight of rough-ground castor and 8 % by weight of twice-purified potassium sulphate (K2SO4). The rough-ground castor contains 75.0 to 82.0 % by weight of organic substance, 5.0 to 6.0 % by weight of total nitrogen (N), 2.0 to 2.5 % by weight of total phosphate (P2O5), 1.0 to 1.5 % by weight of total potassium oxide (K2O), 0.7 to 0.85 % by weight of magnesium oxide (MgO), and further 10.0 to 12.0 % by weight of water and about 105 mg/kg of trace elements. The fertiliser according to the invention has especially proved best-suited for turf formation and thorough rooting of soils in relatively high, poor mountain locations damaged by erosion, weathering or skiing. Owing to the fact that the fertiliser can now be produced in pellet form of 2.5 mm diameter, it can be incorporated into the soil even in a strong wind, so that, compared to before, a more intensive fertilisation of the soil is possible. <IMAGE>
Patent DE-3809881-A1 (DE)
Inventor: BLOTENBERG WILFRIED DIPL ING
IPC: F04D27/02
Filed: 1988-03-24
Abstract: In the case of known control methods, faults which give rise to intervention by the governor, for safety reasons operating at increased proportional boosting, result temporarily in reduced surge reliability of the compressor and in prolonged, periodic pressure fluctuations in the consumer mains post-connected to the compressor. The new control method is intended to avoid these disadvantages. 
<??>The new control method is characterised in that in the event of a discrepancy between the position (ya) of the venting valve (21) and the control variable (u) of the governor (5) exceeding a predeterminable limit, the control variable (u) of the governor (5) is readjusted to the respectively current position (ya) of the venting valve (21) by a readjusting circuit (9). In this way transient processes and hence related reductions in the pumping reliability and longer pressure fluctuations are avoided. 
<??>The new method is suitable in particular for the control of large turbocompressors, for example for blast furnace blast generation, air separation, fertilizer manufacture or fluidised bed generation for petrochemical processes.

Title: Thin-film magnetic head
Inventor: KAWAKAMI KANJI
IPC: G11B5/31
Filed: 1988-07-15
Abstract: A thin-film magnetic head has a first magnet core (20), a second magnet core (30) and a conductor coil (10), which is wound in such a way that it passes through between the first magnet core (20) and the second magnet core (30), and also an electrical insulator (11), which fills the space enclosed by the conductor coil (10), the first magnet core (20) and the second magnet core (30). One end of the second magnet core (30) lies opposite one end of the first magnet core (20), with a magnetic gap (9) in between, the other ends of the first and second magnet cores (20; 30) are magnetically connected to each other. Both the first magnet core (20) and the second magnet core (30) have a multilayered structure, which is formed by alternate superimposing of a plurality of magnetic films (1, 2; 4, 5) and non-magnetic insulating films (3; 6), although at the magnet pole surface (7; 8) both magnet cores (20; 30) are composed of a one-layered magnetic film (2; 4). This makes it possible to reduce the decrease in the effective permeability for high frequencies and to improve the read-out properties when actuating the magnetic head at high frequency. <IMAGE>

Title: Connected devices for diesel engines for reducing the soot particles contained in the exhaust gases
Inventor: BOERGER HANS DIPL ING
IPC: F01N3/26
Filed: 1988-07-21
Abstract: The invention relates to connected devices for exhaust systems of diesel engines for reducing the soot particles contained in the exhaust gases by direct combustion in the exhaust gas flow by means of a burner system with high flame core temperature and a flame intensity varying as a function of the exhaust gas flow. It also includes in a divided process the use of such a burner system for indirect combustion of the soot particles agglomerated on the surface of a star filter connected downstream in the exhaust gas flow and rotating at low speed. The invention furthermore relates to the use of the abovementioned burner system for the separate combustion of the soot particles agglomerated on the surface of a centrifugal filter, which particles are centrifuged at high speed by the centrifugal forces in a combustion chamber which is located outside the filter body. This process is assisted by a radial type compressor formed with the filter body, by means of which compressed intake air, diverted into a hollow chamber formed by the structure of the filter body, counteracts the exhaust gas flow. According to the invention, such an effect can also be achieved by the admission of compressed air from a vessel, remote from the working area of the engine in question, with the pressure and volume necessary for this purpose. In such an embodiment, the high flame core temperature of the burner system connected upstream of the combustion chamber ... Original abstract incomplete.
