Patent DE-4324931-A1 (DE)
Inventor: KOPINKE FRANK-DIETER
IPC: A62D101/22
Filed: 1993-07-24
Abstract: The invention relates to a process for the reductive dehalogenation of halogenated hydrocarbons contained in mixtures of solid or liquid substances by treating these substances with sodium in liquid ammonia. According to the invention, halogenated hydrocarbons can be destroyed in this manner rapidly and completely without preceding extraction even if they are present in the sorbed state on solid matrices, such as activated charcoal, ash, river sediments, soils and the like.

Title: Improved engine oil circuit for the piston valve engine
Inventor: KUHN HELMUT
IPC: F01L11/02
Filed: 1993-08-04
Abstract: In the oil circuit described in patent application P 4229864.4 too much oil is consumed since it passes out through the exhaust with the exhaust gas. By incorporating two pumps, independent of one another, into the oil circuit it was possible to determine the oil feed more precisely. By fitting an oil retainer ring to the cylinder wall it was possible to retain the excess oil between piston and cylinder wall, delimited by the piston ring and oil retainer ring. For this purpose it was necessary to rotate the entire engine so that the crankcase is now always fitted at the top. In addition the engine oil feed lines were laid beyond the piston top dead centre, that is closer to the crankcase and on the far side of the piston ring. The return lines which terminate in the oil tank above the oil level are now situated above the feed lines directly beneath the oil retainer ring. A suction pump driven by the crankshaft provides for the necessary negative pressure above the oil level.  The outlet line extends into the exhaust, for breathing. The other oil pump is electrically driven and is controlled by the central computer chip.  The required data are worked out on the test bench. Any necessary re-adjustment of the said oil feed pump is possible by means of a potentiometer during the routine inspections. The said oil circuit is designed especially for the single-stroke, supercharged, computer-controlled combustion engine with piston valve timing... Original abstract incomplete.

Title: Process and apparatus for isolating impurities from multicomponent exhaust gas streams in a plurality of stages
Inventor: SCHLICHT BURKHARD DIPL ING
IPC: C07B63/00
Filed: 1993-08-11
Abstract: A process is introduced for isolating impurities from multicomponent exahust gas streams in a plurality of stages, for example hydrocarbons from highly concentrated gas streams or vapours of organic liquids, in which the constituents are separated by gas permeation and adsorption. The process is carried out in the following steps:   a) the outlet-side content of impurities in the clean gas stream to be released is set by controlling the partial pressure upstream of the membrane separation stage and the membrane separation surface to a virtually constant value by cooling and adsorption of the permeate gas stream, which is enriched with impurities, downstream of the membrane separation stage, the desorption gas and the inlet gas stream; b) downstream of the membrane separation stage, a partial-pressure drop is continuously generated in the direction of the liquid by corresponding ejection of the condensate-hydrocarbon mixture and addition of hydrocarbon mixture; c) the content of pollutants in the inlet gas stream is specifically concentrated by means of condensate-hydrocarbon mixture until this content is safely above the explosion limit.   <IMAGE>

Title: Pressure-medium connection inside a hollow space
Inventor: OTTO ALBRECHT DIPL ING
IPC: F16L55/115
Filed: 1993-08-20
Abstract: To improve the venting capacity of hollow spaces in hydraulic units in which the connection for the pressure-medium discharge cannot be placed at the topmost point of the hollow space, it is proposed to provide a restriction in the cross-section of flow from the topmost point of the hollow space to the discharge connection. Consequently, air which collects in the top area of the hollow space is entrained like a water-jet pump and conveyed out of the hollow space. <IMAGE>

IPC: E03F7/10
Filed: 1994-06-09
Abstract: The method involves cleaning aqueous sludge from a collection container (13) by sucking it through a pipe (12) into a transportation container (1). A quantity of the water separated from the sludge is diverted into a container (39), which is then sealed off and pressurised.

Patent DE-4424601-A1 (DE)
Title: Two=stroke IC engine with adjustable valve control
Inventor: EISENKNAPPEL ALFRED
IPC: F01L1/04
Filed: 1994-07-13
Abstract: The engine (1) has a camshaft (3) mounted in the cylinder head (2). The camshaft is connected to the crankshaft (4). A connecting rod (5) joins the control piston (6) and the camshaft. A valve (7) of typical construction is built into the connecting rod/piston assembly and it is controlled by a cam (8) eccentrically mounted on the camshaft. As the control piston sinks, it empties the combustion chamber (10) and sucks new mixture into the cylinder head through the inlet hole (11). As the piston rises, the valve opens briefly under the control of the eccentric cam. The new mixture is thus drawn into the combustion chamber. Here it mixes with air drawn in via the crankcase. As the valve closes, the work piston (14) compresses the mixture to ignition.

IPC: G01N21/64
Filed: 1994-08-25
Abstract: A procedure for examining living tissue observes the optical reaction of such tissue to a pulsed laser source via the luminescent and fluorescent effects generated by beam scatters. An assembly for e.g. the measurement of NADH concentration in liver tissue incorporates a fibre optic (1) scanning probe which provides a conduit for the excitation pulses from the laser (7) and a return path for the fluorescent response (3) of the NADH molecules  and unabsorbed return energy (4). The outgoing and return signals are separated by at time interval reference to fibre optic length by a synchronising probe via the semitransparent mirror (8) and detector (9). Previously determined stored data (18) enables real time diagnosis due to self adjustment of system to change of optical parameters in tissue.
