Patent DE-3523715-A1 (DE)
Title: Tail assemblies which can be recessed
Inventor: MAIER ROLAND DIPL PHYS
IPC: B64C9/36
Filed: 1985-07-03
Abstract: In order to avoid the high drag and the high weight of aircraft tail assemblies, the control and stabilisation functions are taken over by a plurality of small control vanes (which can be extended and withdrawn) having an aerofoil profile which are fitted at suitable points on the aircraft surface. Aerofoil profiles offer the best conceivable ratio of control force to drag. The magnitude of the drag is further reduced as the necessity for flightpath corrections reduces, for example flight in a low-turbulence air layer. If the control vanes are installed in pairs with opposing force effects, braking forces can be produced in a continuously variable manner by extending them simultaneously. As a rule, control vanes are controlled by an on-board computer. The manoeuvrability of the aircraft is improved. Safety questions relating to defective operation in the case of sensors, computers and control vanes are solved by redundancy. In the case of military aircraft, exiting from the aircraft using the ejector seat is simplified.

Title: Process for purifying foul water and apparatus for purifying foul water
Inventor: KWIETNIOWSKI LUDWIK
IPC: C02F1/465
Filed: 1985-11-21
Abstract: The invention solves the problem of effective purification of foul water and is intended in particular for use on means of transport, predominantly on ocean-going vessels. According to the invention, the foul water is first comminuted and homogenised, that is in a circulation which is composed of a through-flow screen (19), a storage chamber (1) and a circulation pump (7). Foul water treated in this manner is passed into the electroflotation chamber (3), where it is subjected to an electrolytic impregnation by a medium which causes the coagulation of the impurities. The waste water stored in the intermediate chamber (4) and the settling tank (5) is then subjected to flocculation and sedimentation, and the resulting light and floating impurities and the precipitates sinking downwards are removed by means of a skimmer driven by a motor (26) and a programme-controlled valve (18). In the final phase of the purification, the foul water is sterilised (bacteriologically) in the disinfection chamber (6) by means of a medium fed from the metering apparatus (9). The purified foul water is removed to the outside through the outlet nozzle (27) by means of the draining pump (8). <IMAGE>

Patent DE-3601281-A1 (DE)
Inventor: RAPP KNUT M DIPL CHEM DR
IPC: C07D307/46
Filed: 1986-01-17
Abstract: The present invention refers to a process for preparing 5-hydroxymethylfurfuraldehyde, which is also called HMF. This compound was yet prepared by dehydration of fructose-containing carbohydrates in the presence of various catalysts. Nevertheless, the separation of HMF from starting material, by-products and organic solvents was difficult and disadvantageous, especially by the presence of organic solvents. Surprisingly, it came out, that it is possible, to separate 5-hydroxymethylfurfuraldehyde from reaction mixtures, which are obtained by reactions of saccharides with an acid catalyst, in great purity and good yield with exclusive utilization of water as solvent, by means of ion exchangers, and to crystallize it out from chromatographic fractions.

Filed: 1986-07-12
Abstract: The process for simultaneously separating off sulphur dioxide and nitrogen oxides from flue gases with the aid of electron beams and addition of an alkaline reagent operates in such a manner that the flue gas conditioned only with respect to temperature and water content and having velocities conventional in flue gas ducts of up to 20 m/sec   a) is accelerated in the irradiation chamber to velocities of over 20, preferably over 25, m/sec and is bombarded by electron beams which have an accelerating voltage below 400 kV, b) the alkaline reagent is added immediately after the irradiation and c) solid reaction products are formed, from the resulting mixture, in a reaction space at velocities of 5-15 m/sec and are then separated off.   The irradiation chamber of the apparatus is preferably designed as a Venturi tube or flat Venturi nozzle, while the subsequent reaction space has a larger cross-section than the feed for the conditioned flue gas.
Patent DE-3626156-A1 (DE)
Title: Radio network
Inventor: MUELLER KLAUS-DIETER DIPL ING
IPC: H04W88/02
Filed: 1986-08-01
Abstract: A radio network is proposed which contains at least two stationary or mobile radio stations, at least one radio station of which can be called by means of selective calling. At least one of the radio stations (10, 11) is associated with a portable transceiver which can be called by another individual selective call. So that a selective call received and recognised at a called radio station can be recognised as a call by the user in spite of his absence, the selective calls (S1) received several times in the case of an absence are counted. When a certain number n of selective calls has been reached, the called radio station (11) automatically sends out a selective call intended for the associated portable transceiver (14) which triggers a visible or audible signal in the portable transceiver. In this manner, it is not required that a user leaving the radio station operates a special change-over switch by means of which the radio station is then caused to forward incoming selective calls by sending out a selective call intended for the associated portable radio set (14). <IMAGE>

Title: Hanging, noise-insulating device for objects to be hung up
Inventor: MANTEL JUVAL DR ING
IPC: A47J45/02
Filed: 1988-01-21
Abstract: On walls, preferably of kitchens and other sanitary blocks, but also in commercial and industrial establishments, there are fixed devices, equipment and machines which produce structure-borne noise, whether it be through the motors they possess or through the banging of hard objects (e.g. the closing of doors and cabinets (cupboards)). These structure-borne noises are transmitted through structures and disturb the neighbourhood. It is therefore necessary to protect against the structure-borne noise for devices to be hung up. The solution according to the invention consists in using a symmetrical pair of rails insulated against structure-borne noise, one of the rail pairs being fixed on the wall, the second rail pair being fixed on the object (e.g. cabinet) to be hung up. The diagram shows the hanging-up, e.g. of a cabinet, with the aid of the device, an additional damping strip in the lower part being used as additional spacer.
