Patent DE-19861164-A1 (DE)
Inventor: KURPAS ANTON
IPC: F02M69/04
Filed: 1998-12-21
Abstract: The invention relates to a carburetor for internal combustion engines, comprising a throttle device (1) which is positioned in an intake port (3) of an internal combustion engine and can be pivoted about a pivot axis, as well as an output device (5, 6) for the fuel being supplied which in the direction of flow (8) of the intake air is positioned downstream of the throttle device (1) in the intake port (3). The output device (5, 6) discharges the fuel into the intake port (3) in such a direction (7) that especially during lower part-load operations of the internal combustion engine when the throttle device (1) is only slightly open the fuel substantially strikes at least sections of said throttle device. The throttle device then atomizes the fuel in the intake air in the opening (14) embodied between the throttle device (1) and the intake port (3) in the area of greatest intake air flow speed.

Title: Production of ultra-pure water in semiconductor plants comprises varying final degree of purity to suit various processes
Inventor: WELTZER MARTIN
IPC: C02F9/00
Filed: 1999-01-12
Abstract: Water is fed from the make-up stage to separate polishing stages so that water of varying degrees of purity can be produced, depending on the actual requirement of the particular process in which it is used. The parameters of purity cover the presence of oxygen, silicon dioxide, metals, anions, organic carbon and particles above a given size.  Water for these plants is produced in three stages: (1) Pretreatment of raw water, (2) a secondary make-up and (3) the final, polishing, stage. Conventionally only water from the polishing stage is used for all processes. It is now proposed to feed water from the make-up stage to separate polishing stages so that water of varying degrees of purity can be produced, depending on the actual requirement of the particular process in which it is used. The parameters of purity cover the presence of oxygen, silicon dioxide, metals, anions, organic carbon and particles above a given size. The wafer polishing section, for instance, could use make-up rather than polished water. The subdivision of polished water quality also permits the used of cheaper piping materials in all but the purest water delivery systems.

Title: Method to generate multicolored patterns, to test color vision or reactions; involves moving transparent color disc over light diodes to form image of mixed color
Inventor: KOEST GERT
IPC: A61B3/06
Filed: 1999-03-11
Abstract: The method involves using a number of switchable light diodes (1) and at least two transparent color segments of different colors, which can be moved in front of different light diodes. The discs are moved over the diodes so fast that a flicker-free image of mixed colors is obtained.

Title: Power transmission mechanism using metal belts
Inventor: LEE JONG-WAN
IPC: F16H9/20
Filed: 1999-07-16
Abstract: The mechanism uses metal belts (45,47) as a belt connecting a driving pulley (17) and a driven pulley (25). Each metal belt rotates at the same speed rate around pulleys, therefore the angular velocity of each metal belt on a pulley is identical. Since each metal belt is disposed to be separated from a neighboring   metal belt, tolerance in length of the belt is not strict   and correction can be made by adjusting the width corresponding to the length.

Patent DE-19936548-A1 (DE)
Inventor: JEKERLE JIRI
IPC: C07C4/04
Filed: 1999-08-03
Abstract: The invention relates to a method for cracking hydrocarbons, especially for producing olefins, whereby a mixture consisting of hydrocarbons and water vapor is heated in a cracking furnace up to a temperature ranging from 750  DEG C to 900  DEG C, and the resulting cracking gas which contains hydrogen is immediately cooled after the heating process in a cracking gas cooler to a temperature lower than approximately 650  DEG C. If heavy products are present, the cracking gas is subsequently subjected to an additional cooling by quenching and is then liberated by separating out heavy oil and gasoline. Afterwards, water vapor is removed by quenching from the cracking gas containing light products. This cracking gas is compressed to at least 20 bar by a compressor, is liberated from residual water by drying, is cooled in a deep cooling installation, and is fed into a plurality of rectifying columns in order to separate out the light products. Selective membrane diffusion is used to extract a portion of the hydrogen from the cracking gas in the direction of flow of the process medium upstream from the deep cooling installation. The invention also relates to an installation for thermally cracking hydrocarbons, especially for producing olefins.
