Title: Motor vehicle having a folding top and a wind deflector
Inventor: WURTZ RICHARD
IPC: B60J7/22
Filed: 1988-09-29
Abstract: A motor vehicle having a folding top has as wind deflector (6) two air-guide bodies (7, 8) which extend in parallel along the front roof crossrail (4), are arranged one above the other and are connected to each other. Those surfaces (9, 10) of the air-guide bodies (7, 8) which lie opposite each other run towards each other at the rear in the shape of a nozzle. Provided on the top side of the roof crossrail (4) is a recess (5) which receives the two air-guide bodies (7, 8) in the rest position in which the upper surface (14) of the upper air-guide body (7) seals the recess (5) of the roof crossrail (4) upwards in a flush manner. Furthermore, a lifting device is provided for moving the two air-guide bodies (7, 8) from the rest position into the operative position, and in the operative position the upper surface (10) of the lower air-guide body (8) seals the recess (5) of the roof crossrail (4) upwards in a flush manner. <IMAGE>

Title: Process and plant for treating waste waters laden with light liquids
Inventor: LOSERIES HANS GEORG
IPC: B01D17/025
Filed: 1988-12-20
Abstract: The invention relates to a process for the purification of waste waters (effluents) contaminated with dispersed or temporarily emulsified light (low density) liquids, as are formed, in particular, in the high-pressure cleaning of vehicles and vehicle components. The purification of these waste waters in a reasonable time is not possible either in pure gravity separators or in separators optimised by coalescence internals. The purification now succeeds by the separator operating by the coalescence and gravity principle being impinged in throttled batch operation and for this purpose, upstream of this is connected a stack stage with deliberate draining.

Title: Two-stroke motor with stratified air scavanging
Inventor: TUCKEY CHARLES HENRY
IPC: F02B25/04
Filed: 1989-01-27
Abstract: A two-stroke motor is described which has an air inlet in the crank housing and an air/fuel spiral channel which surrounds the cylinder wall and at the same time rises from the crank housing to an inlet in the cylinder head in order to bring about cooling of the cylinder. A fuel injection device directs fuel into the connection channel. Air and fuel enters the cylinder head through a one-way valve and curved blades cause the air and the fuel to eddy in order to bring about a stratified formation of fuel and air. An exhaust gas channel in the cylinder wall has an adjustment throttle in order to control the outlet of exhaust gases directly and the inflow of fuel/air mixture directly, as a result of which the power level of the engine is controlled.

Title: Gas turbine, in particular for driving motor vehicles
Inventor: RENKEN ALFRED
IPC: F02C3/14
Filed: 1989-03-07
Abstract: Chiefly because of the high production costs of gas turbines, it has not been possible to date to establish the use of gas turbines for driving motor vehicles or other machines having a relatively low power demand. In addition, a compact design of the gas turbine is a precondition, particularly in the case of accommodating the gas turbine in a motor vehicle. The novel gas turbine is to have a simple and compact design, and yet to supply sufficient power for driving, in particular a motor vehicle. The novel gas turbine is designed in such a way that the radial compressor and the radial turbine are arranged immediately adjacent on a common shaft and the combustion chamber connects the radial compressor and the radial turbine to one another on its circumference. Driving of motor vehicles.
