Patent DE-3637388-A1 (DE)
Title: Wheel suspension for lowerable vehicle bodies with load-dependent brake pressure controller
Inventor: SIEBEN HANS-HERMANN
IPC: B60G5/04
Filed: 1986-11-03
Abstract: In the main patent, in each case two half-axle pipes which form the sprung counterbearing for in each case one rotary rod spring or rubber rotary spring for the suspension of a wheel, are rotatably mounted independently of one another in a continuous supporting pipe on the vehicle body. The half axle pipes bear on their end which protrudes out of the supporting pipe and is adjacent to the rotary swing arm a control arm in which a hydraulic cylinder engages and with which the half axle pipes can be rotated in order to lower the vehicle body. A load-dependent brake needs to be made possible for such a wheel suspension. A measured value sensor detects the angle between the wheels swing arm and the adjacent control arm and passes this on as a control variable for the load-dependent braking valve. The measured value sensor here can have a cam plate which interacts with a cam in order to convert the rotary movement into a longitudinal movement. The passing on of the control variable can take place electrically or hydraulically. The invention can be used in all vehicles with non-driven axles.

Patent DE-3708045-A1 (DE)
Title: Fog (mist) meter (nephelometer) having an impactor
Inventor: PAFFRATH DIETER DIPL PHYS DR
IPC: G01N15/02
Filed: 1987-03-12
Abstract: In a fog meter, an impactor which can be set rotating by means of a drive has an arrangement of a plurality of parallel, round rods which are arranged horizontally aligned one above another and preferably consist of Teflon (registered trademark). Furthermore, the fog meter is assigned a visibility meter (scopograph) by means of which, in addition to determining the visibility, the drive motor of the impactor is switched on or off in fog as a function of the visibility respectively prevailing. The use of the visibility meter ensures that the impactor, which can be set rotating, of the fog meter is reliably always switched on only if precipitation of fog water is effective and can be evaluated, and this is not the case until fog in which visibility is below 400 m; at the same time, the impactor of the fog meter is thereby prevented from being contaminated unnecessarily by aerosol particles, dust particles and the like in the event of excessively high visibility.

Title: Ammonia removal from combustion ash esp. fly ash - using small amt. of water, and drying under alkaline conditions with reduced drying energy
Inventor: HAESE ILONA
IPC: A62D3/00
Filed: 1987-04-04
Abstract: Sepn. of NH3 and opt. ammonium cpds. from ash from combustion esp. fly ash, involves treating the ash with water and liberating the NH3 under alkaline conditions, if necessary in the presence of a basic additive and drying. The novelty is that the opt. hot ash, coming from ash sepn. is moistened with water and/or steam to a H2O content of max. 15 wt.%. Pref. the ash is mixed with hot water, opt. contg. a basic additive and pref. contg. a wetting agent to reduce the surface tension. Removal of the NH3 liberated is assisted by purging air in contact drying of the ash. USE/ADVANTAGE - The drying energy can be reduced (cf. the usual method in which the ash is made into a cake with 30-40 wt.% water). The process is useful for removing residual NH3 and ammonium cpds. used to reduce the NOx content of the flue gas e.g. from power stations.

Title: Tensile-force delimiting means in a gas-supply line
Inventor: JESCHKE IMMANUEL
IPC: F16L55/10
Filed: 1987-06-02
Abstract: The invention relates to a tensile-force delimiting means in a gas-supply line, comprising two metal-pipe pieces which are connected to one another by a socket and whose fixed connection is released when a predetermined tensile force is exceeded. The object of the present invention is to provide a simple design of a tensile-force delimiting means which can be easily fixed in its rupturing region and offers the possibility of rupturing even when subjected to bending forces and which makes it possible, in particular, automatically to close off the ruptured gas-supply line, with the result that gas escapes at the rupture point only during rupturing, and even then only in a small amount. The invention consists in the fact that the two metal-pipe pieces are connected to one another by a rod, that said rod is arranged in the interior of the tensile-force delimiting means, that there is arranged, in each pipe, a web with a hole through which the rod extends, and that a predetermined breaking point is formed in one, through one or on one of the rod/web components.

Patent DE-3725979-A1 (DE)
Title: Hydrostatic axial-piston machine
Inventor: MUELLER ACHIM DIPL ING
IPC: F04B1/12
Filed: 1987-08-05
Abstract: The invention concerns a hydrostatic axial-piston machine with a rotating cylindrical body whose pistons, located in cylindrical holes, are connected to sliding blocks that are pressed against a bearing surface of a sliding plate by means of a platen to generate a stroke. The invention is implemented by having, in an axial-piston machine (pump or engine) with a platen applying a load inside, the outside diameter of the sliding plate bearing surface set back so far that the bearing surface of every sliding block crosses an edge bounding this outside diameter. While crossing the edge, the bearing surface of each sliding block has a positive overlap with it. Due to the compensation of the forces trying to swing the sliding block around the ball of the piston outwards, the sliding block is prevented from tipping over. <IMAGE>

Title: Propulsion arrangement for hydroplanes
Inventor: GERDSEN HANS GERD DIPL ING
IPC: B63H5/16
Filed: 1987-09-24
Abstract: The invention concerns a propulsion arrangement for hydroplanes, in particular seagoing hydroplanes with bearding angle and dual propulsion plant. The invention deals with the problem of creating a propulsion arrangement for hydroplane drives by which optimisation of the interaction between the hull and the propulsion device, and thus a higher degree of propulsive efficiency, can be achieved. This problem is solved according to the invention by the sliding surface having at least one tunnel open at the bottom in the afterbody, in which a propulsion device is located partly recessed, below the end of the sliding surface. The tunnel cross-section at the site of the propulsion device approximates to the cross-sectional area of the propulsion device, with a small tolerance, and has a roughly semicircular shape. The tunnel is let into the sliding surface, runs approximately in the direction of the streamlines, and its width remains roughly constant while its cross-section tapers forwards.

Title: Discarding sabot having a low intrinsic mass for a sub-calibre, high-speed flying projectile
Inventor: WALLOW PETER DIPL ING
IPC: F42B14/06
Filed: 1987-10-20
Abstract: The discarding sabot (24) is longitudinally slotted and has in the front region centring holders (44) which are directed inwards against the flying projectile (10.3) and, in the tail region, a centring surface or centring surfaces (36) assigned to the flying projectile (10.3). An opening (59) in the discarding sabot (24) at the tail end is provided with an internal thread (62) for accommodating a screw-in element (60) which, at the front, is used as a seat for a tail-surface region of the flying projectile (10.3). Elements (66, 68) in the form of strips can be compressed as required in the circumferential region of the discarding sabot (24). Conical surfaces (76) on the discarding sabot (24) simplify the insertion of the arrangement at a rate which is normal in the case of automatic weapons, an insertion shock not leading to any axial relative movement of the flying projectile (10.3) with respect to the discarding sabot (24), as a result of a front retaining region (41) and the centring surface or surfaces (36). Those parts of the discarding sabot (24) which are formed by the said longitudinal slot and are held together in the front region by the element (66) in the form of a strip are reversed like levers, with the element (66) in the form of a strip tearing in the direction of the arrows (K), under the influence of the air which is incident from the front, and at the same time release the flying projectile (10.3) for movement in the direction of the arrow (S). <IMAGE>

Abstract: PCT No. PCT/EP88/01070 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Nov. 24, 1988 PCT Pub. No. WO89/06352 PCT Pub. Date Jul. 13, 1989.The invention relates to a process and device for measuring the effective viscosity and the elastic properties of coatings. Known measuring processes and measuring devices based on the "rolling ball method" suffer from drawbacks, namely run formation and sinking of the relatively heavy solvent vapors, due to the inclination of the coated sheet metal. To overcome these drawbacks, rolling movements are imparted to a magnetizable ball (1) displaced from its rest position in a magnetic field, during movement of the horizontally disposed substrate, under the influence of the field gradient of a permanent magnet or electromagnet (4) located below the substrate. The rolling movements are used as the basis for the measurements.

Title: Nitric acid production with an associated process for cold generation
Inventor: FUDERER ANDRIJA DR ING
IPC: C01B21/26
Filed: 1988-02-20
Abstract: Ammonia is vaporised with the generation of cold. The ammonia vapours are absorbed in aqueous ammonia solution with the liberation of heat. The enriched ammonia solution thus obtained is brought into contact with the oxidation gas or air, with ammonia being desorbed from the solution and generating additional cold. The air/ammonia mixture obtained is used, by means of catalytic oxidation, for the production of nitrogen oxides and nitric acid. In this way, the ammonia is used for doubled cold generation and is only then catalytically oxidized. In this cold generation, no heat and no compression energy are consumed. The cold obtained can also be utilised in ammonia synthesis.

Title: Method of keeping the level of the secondary vapour cover constant in two-phase soldering
Inventor: HOEGER HERBERT
IPC: B23K1/015
Filed: 1988-03-31
Abstract: Method of keeping the secondary vapour cover constant in two-phase condensation soldering, a feed line being directed into the upper area of the secondary vapour zone and a feed-quantity control means being inserted in the feed line. The leading of the feed lines into the area above the secondary vapour zone ensures that the temperature of the feed line does not lie above the boiling point of the secondary medium, as a result of which the formation of vapour bubbles in the feed line is avoided. The feed-quantity control means keeps the level of the secondary vapour cover constant, which thereby becomes independent of the filling level of the supply reservoir for the secondary vapour medium.
