Title: Wing system for fixed-wing aircraft having two lift-generating wings
Inventor: UELLENBERG MANFRED
IPC: B64C39/06
Filed: 1987-03-31
Abstract: In order to reduce the induced resistance in fixed-wing aircraft having two lift-generating wings, a swept-back wing with a swept-forward wing offset in height on the fuselage relative to the first wing is connected to the wing tips by means of an arcuate or shaped piece. Integrated in this wing system, which is to be regarded as endless, at the end of the fuselage is a vertical empennage, or a plurality of vertical empennages which can be of different configuration are integrated in the rear wing. The system can be composed of a plurality of wing segments or of one piece. The arcuate or shaped parts connecting the wing tips do not interfere with the flow and can have baffles which maintain lift. The selection of the wing profiles and of the angles of the profile setting, the sweeping and the dihedral, as well as of the length of the empennage lever arm depends on the respective requirement. Meterable air brakes of known designs are provided in the system in order to replace the reduced resistance during low-speed flight. The shape arising from the characterising features can also be used to increase efficiency in the case of rotors for rotorcraft (rotor vehicles) and in the case of vanes, which receive an incident flow or generate a flow, for airscrews and water propellers. <IMAGE>

Title: Device for measuring the true speed of motor-driven vehicles
Inventor: ZIEGENBEIN WILHELM DR ING
IPC: G01P3/36
Filed: 1987-04-14
Abstract: The invention relates to a device for measuring the true speed of motor-driven vehicles. Two photoelectric optical devices are used, by means of which a location on the roadway is scanned. They move synchronously with the wheels and are situated next to one another. The two photoelectric parts are connected back to back. Because of the nonuniform surface of the roadway, the photocurrents generated do not cancel one another out. A voltage is produced. In the event of a deviation in the vehicle speed from the circumferential speed of the wheels, this voltage vanishes completely or partially, since similar, blurred images now act on the two photo devices. This effect is used to display the speed or to execute control.

Patent DE-3739619-A1 (DE)
Title: Funnel vortex generators and heat exchange (transfer) surfaces for heat exchangers
Inventor: FIEBIG MARTIN PROF DR ING
IPC: F28F1/32
Filed: 1987-11-23
Abstract: The invention encompasses shapes, arrangements and the production of generators of funnel vortices for increasing heat transfer at heat exchange surfaces for free and/or forced convection. The axes of the funnel vortices are aligned essentially in the main flow direction and the funnel vortices circulate the heat transfer medium in a pinpointed fashion. Owing to the strong rotation generated in the flow at right angles to the main flow direction, the warm or cold fluid layers near the wall continuously replace the cold or warm fluid layers away from the wall and produce a substantial rise in the heat transfer in conjunction with a relatively slight rise in the pressure losses and/or flow losses. The invention further relates to heat exchange surfaces with funnel vortex generators. Technical applications are heat exchange surfaces of finned (fin-and-tube) heat exchangers, gilled heat exchangers, plate heat exchangers and spiral heat exchangers, as well as heaters, radiators, convectors, housings of calorific electrical and electronic devices, radiant heat exchangers, central volumetric and/or tube-type radiation detectors for the use of solar radiation at high temperature and, furthermore, condensers and evaporators of refrigeration plants or condensers of dry-cooling towers. <IMAGE>

Patent DE-3844422-A1 (DE)
Inventor: BRUEGGENDICK HERMANN DIPL ING
IPC: B01J8/12
Filed: 1988-12-30
Abstract: An adsorbent in granular or lump form is introduced into a reaction chamber (14) and taken out of it through a grid of channels formed by a multiplicity of separate feed and discharge hoppers (18 and 20). Most of the waste gas is fed into the reaction chamber from one side, so that it spreads out over the whole of that side of the chamber, while a small proportion is fed in through the bulk material distributor cone (17). The flow of waste gas through the reaction chamber (14) is distributed so that the adsorbent in almost all parts of the reaction chamber participates uniformly in the adsorption process. Several reaction chambers with several reaction layers are arranged in series in the gas line. After leaving the first reaction chamber (14), the partly cleaned gas is fed back under the discharge plate (9) in such a way that it passes round, and thus heats, the discharge hoopers (20) and the discharge tubes (21, 22), hence preventing the formation of condensation. The adsorption unit (1) can be used to clean waste gases in refuse-incineration plants, different undesirable constituents being removed separately in different adsorption layers (25, 27 and 26, 28) and further processed.
