Title: Variable flow IC engine inlet manifold - has helical compartment for each cylinder with length adjusted by altering inlet openings
Inventor: RASLAG KLAUS
IPC: F02B75/20
Filed: 1988-07-22
Abstract: By adjusting the operative length of the inlet manifold (4) for a vehicle engine, the fuel and air supply to the engine is adjusted according to the engine speed. The interior of the manifold is divided by internal flanges into helical compartments (5) around an inner cylinder (7) with an inlet opening (9) for each engine cylinder. The size of the openings is adjusted by rotating the inner cylinder to modify the operative length of the compartments. In an alternative design, the rotary inner cylinder carries a sliding plate with openings for the different compartments. The travel of the plate is limited by lugs projecting from the openings. ADVANTAGE - An optimum change is ensured for all speeds.

Title: Process and apparatus for producing a rich gas stream
Inventor: SPORER JOSEF DIPL ING
IPC: B01D53/14
Filed: 1988-11-29
Abstract: A process and an apparatus are described for producing a rich gas stream from exhaust gases, which rich gas stream is obtained by scrubbing with a solvent and subsequent regeneration of the solvent. In order to produce a rich gas stream in a simple and cheap manner, which rich gas stream is independent of the operation of upstream or downstream plants, it is proposed that the rich gas produced is subjected in whole or in part to a further scrubbing. The process is suitable, for example, for SO2-rich gas production from the exhaust gas from roasters (Fig. 1). <IMAGE>

Title: Process and apparatus for dynamic gas mixing
Inventor: JEHLE WALTER DIPL ING
IPC: B01F23/10
Filed: 1988-12-14
Abstract: The invention relates to a process and an apparatus for carrying out the process according to the invention, a vacuum being generated in a heated evaporator by an ejector operated by a motive gas, the liquid to be evaporated being fed to the evaporator and evaporated on the evaporator surface and the vaporised liquid being sucked in by the ejector and mixed there with the motive gas. By the use of the invention described it is possible to vaporise any desired molar flow rate and thus to achieve a match to gas-phase reactions. By means of evaporation in vacuo, the evaporation temperature can be kept low so that even unstable substances can be vaporised, and the dilution of the vaporised liquid with the motive gas decreases the dew point of the gas mixture. <IMAGE>

Title: Flat display device
Inventor: TISCHER KURT MANFRED
IPC: H01J29/86
Filed: 1989-04-07
Abstract: A flat display device (10) has a front screen (12) and a trough (13) as well as a base plate (17) to which metal strips have been fitted. The glass plates, that is to say the front screen and the base plate, consist of glass having a coefficient of expansion of approximately 120.10<-7>K<-1>. The trough and the metal strips are constructed from unalloyed iron sheet. Respectively corresponding glass plates and metal parts are connected by means of a connection means whose coefficient of expansion corresponds to that of the glass. Since unalloyed iron is inexpensive and easy to treat, it is easy to produce flat display devices in which metal parts which are connected to glass plates consist of unalloyed iron and the glass plates and the corresponding connecting materials have the mentioned coefficient of expansion. <IMAGE>

Title: Process for continuous solvent recovery
Inventor: JIRENEC KARL ING
IPC: B01D53/06
Filed: 1989-05-29
Abstract: A process is proposed for continuous recovery of solvents, such as hydrocarbons or halogenated hydrocarbons, from a process gas stream in which the solvents are adsorbed to solids from the process gas stream in a first stage, desorbed in a second stage by means of a preferably hot regeneration gas and, in a third stage, are condensed from the laden regeneration gas, if necessary after drying, and separated off. This is achieved by using liquid droplets, in particular solvent droplets distributed in the laden regeneration gas at least essentially as a heat removal medium for condensation of the solvent treatment. In addition, an apparatus for carrying out this process is proposed having an adsorber which is advantageously designed as a segmented drum adsorber, the segments of which are designed for radial or axial flow, a regeneration gas circuit, if appropriate an adsorption drier for drying the laden regeneration gas and a solvent condenser, the solvent condenser being equipped with a feed device, in particular an atomising device or spraying device for finely divided introduction of a heat removal liquid in direct contact with the laden regeneration gas.

Title: Despatch of useful loads from space station - involves counteracting orbital velocity of station by rotating load
Inventor: FRIEBEL WOLF-CHRISTOPH DR
IPC: B64G1/52
Filed: 1990-07-03
Abstract: A useful load is despatched from a space station and returned  to earth in the following way. The load is attached to the end of a cord which is rotated relative to the space station.  The load is released when its tangential velocity is approx. equal to the orbital velocity of the space station but in the opposite direction. The velocity of the load relative to earth is thus approx. zero so that no retro-rockets are required nor is the load subjected to kinetic heating on re-entering the earth's atmos.  The initial rotation is achieved by means of an electric motor powered by solar cells.   Counterbalance weights eliminate any reaction force being imposed on the space station. USE - Space research.  Launching of loads from space station to return to earth.
