Patent DE-19541521-A1 (DE)
Title: Electrical efficiency improver for flow of special gases
Inventor: ROTH HANS DR ING
IPC: F02B41/00
Filed: 1995-11-08
Abstract: The electrical efficiency improver is based on burning the special gas of a conventional internal combustion engine in a block heat power unit which creates heat used to create electricity. The residual heat is transferred via the coolant heat transmitter (2) and exhaust gas heat transmitter (3) to the fluid in the circuit of the heat recovery process. Organic fluid under pressure is vaporised by this heat. The high-pressure steam is used to run a turbine (4), the mechanical energy of which is converted to electricity in a generator (5). The steam is condensed in a condenser (6) and re-pressurised by a pump (7).

Inventor: WILLKE CLEMENS DIPL ING
IPC: F02M51/06
Filed: 1995-12-19
Abstract: The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines in which there is an extended, axial, thin-walled, non-magnetic sleeve (12). At the downstream end said sleeve (12) has a base section (20) running substantially perpendicularly to the otherwise axial extent of the sleeve (12) along a longitudinal valve axis (10). A valve needle (28), firmly secured to an armature (24) and a valve closer (30), can move axially in a through aperture (21) in the sleeve (12). The valve closer (30) operates together with a valve seat (35) on a valve seat body (25), where the valve seat body (25) is pressed into the sleeve (12) and, for instance, thus bears on the base section (20) of the sleeve (12). The sleeve (12), in the form of a deep-drawn sheet-metal component, extends axially over more than half the axial length of the fuel injection valve. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.
Patent DE-19600967-A1 (DE)
Inventor: GOTTWALD THOMAS
IPC: B01D61/00
Filed: 1996-01-12
Abstract: The invention concerns a method, including at least one superfine-filtration stage (7, 10), of filtering the organic solutions which arise in the production of circuit boards. In the method proposed, the chemicals dissolved in the solutions used for the production are separated from the organic solvent, e.g. ethyl diglycol, by ultrafiltration (7) for instance, in order to be able to use the chemicals again. The method proposed has the advantage that savings can be made in materials and energy and, in addition, waste can be reduced significantly or even avoided entirely.

IPC: B03B5/52
Filed: 1996-07-26
Abstract: A process is disclosed for controlling the composition of a product from a device for sizing and sorting mineral raw materials, in particular sand and gravel, which must keep a predetermined finest sand concentration in the sand product quantity. For that purpose, an additional sizing separation of the sand product quantity into a sand fraction (mPr) and into a finest sand fraction (mFSS) to be discharged through the overflow is carried out in the chamber above the level (hFS) of the fluidised bed contained in the chamber. In order to set a predetermined finest sand concentration (C<Prsoll) in the sand product quantity, the level (hFS) of the fluidised bed is regulated in such a way that the proportion of finest sand (m<A) in the loaded amount of raw material can be divided by the fluidised bed into a finest sand proportion permissible as a function of the predetermined concentration (C<Prsoll) to be discharged into the sand product quantity (mPr) and into a finest sand proportion (mFSS) to be discharged through the overflow.
