Title: Process for on-site remediation and chemical long-term stabilisation of deposits having sulphidic contents
Inventor: MUENZE RUDOLF
IPC: A62D3/33
Filed: 1993-05-05
Abstract: In a process for on-site remediation and chemical stabilisation of deposits having sulphidic contents, in particular from ore mining and ore treatment, in which the heavy metal cations and radio element cations are immobilised by an acid-base- and redox-buffer capacity, comprising hydroxides, carbonates and silicates of alkaline earth metals, aluminium and iron(II, III), being generated or stabilised in the deposit, which capacity converts the heavy metal cations and radioelement cations into poorly soluble or insoluble compounds which are included in precipitates of the major constituents such as iron hydroxide and gypsum, the bicarbonate required for the neutralisation and the reducing agent are generated in concentrations of 1-10 milligram-equivalents/l of leachate water by in-situ development of carbonic acid and reducing substances by bacterial oxidation in humus and calcium- or magnesium-carbonate-containing additives and together with the precipitation water or groundwater are fed to the sulphide-containing deposit.

Title: Method for the production of a holographic reflection disc, and a holographic reflection disc
Inventor: BULLINGER WILFRIED DIPL ING
IPC: G02B5/32
Filed: 1993-06-07
Abstract: The invention relates to a method for the production of a holographic reflection disc. It is the object of the invention to improve known production methods for reflection discs of this type such that the angle of diffraction of light is increased under Bragg conditions. As a result of the fact that during the generation of the planes of increased optical refractive index, hereafter called Bragg planes, there is in the carrier layer no transition in the optical refractive index between the medium and the carrier layer, it is made possible to introduce the interfering rays (beams) into the carrier layer at larger incident angles with respect to the plane normal. This measure increases the distance between the interference maxima of the two rays in the carrier layer which determines the distance between the Bragg planes. As a result of the larger distance between the Bragg planes, larger diffraction angles are in turn made possible. The invention has the further advantage that the accommodation in a medium of identical optical refractive index reduces reflections at the surface of the reflection disc when the light rays emerge from the reflection disc, as a result of which the quality of the hologram produced is improved.
Patent DE-4319742-A1 (DE)
Title: Laser ball pen
Inventor: AZDASHT GHASSEM DIPL ING
IPC: B23K26/06
Filed: 1993-06-15
Abstract: The method is suitable for electrically bonding, detecting or treating a surface with the laser beam. For this, a ball (3) mounted in a bond head (1) passes over the surface, in the course of which the ball can absorb laser energy and thereby produce heat, or in the case of a transparent material (glass) the laser energy is directly transmitted to the materials (4, 5) to be joined. In this method, the bond head can pass over the surface of a material, as a result of which a free movement of the laser beam is possible while the parts to be joined are simultaneously pressed together and good thermal coupling during the electrical bonding is thereby achieved. <IMAGE>

Title: Fuel metering for an IC engine - Has fuel enrichment factor as starting value for lambda controller when in closed loop mode
Inventor: ACHLEITNER ERWIN DIPL ING DR
IPC: F02D41/14
Filed: 1993-11-11
Abstract: A procedure for metering fuel on an IC engine (10) uses a lambda control device (17) which operates in either open loop or closed loop mode, depending on engine conditions, and also uses hot-running fuel enrichment when the control mode is closed loop. In this mode, the enrichment factor is used as the starting value for the lambda controller. The engine conditions are derived from the temperature of an exhaust gas sensor (14) and also the engine temperature. The time since the start of the engine is also considered. ADVANTAGE Minimised errors in fuel enrichment

Title: Liquid jet printing method
Inventor: DAUER HORST
IPC: B41J2/07
Filed: 1993-11-25
Abstract: In the liquid jet printing method a dynamic matching takes place between the delay time for the control impulse with regard to the path signals of the recording medium and the temporal fluctuations of the relative speed of the recording medium. The dynamic matching involves associating a nominal or desired delay time with a nominal or desired speed. The actual speed of the relative movement of the recording medium is determined and an actual delay time is determined for a fixed deviation of the actual speed from the desired speed.

Inventor: DERWAND HORST
IPC: F16L55/165
Filed: 1994-06-26
Abstract: The invention concerns a method of replacing a plastic pipe line (15) by a new pipe line (30), the existing pipe line being ripped open and its bore increased by means of ram-driven drilling device (5) to produce a passage whose diameter is greater than the external diameter of the new pipe line, the new pipe line being drawn into the passage thus formed at the same time as the existing pipe line (15) is widened.

Title: Forming field oxide insulating film using LOCOS process for semiconductor device mfr.
Inventor: JANG SE AUG
IPC: H01L21/762
Filed: 1994-12-29
Abstract: After forming a mashing film pattern, an oxide film is locally formed on a parent surface region of the semiconductor substrate by starting the oxidation process, using the mashing pattern. The oxide film is removed for etching a preset region of the substrate surface. Thus an undercut is formed in region located under a side wall of the masking pattern. On the undercut is formed an oxidation preventing film, and an element insulating oxide film is formed on an exposed section of the semiconductor substrate during etching of the substrate preset region.
