Title: Emergency coolant supply - for PWR through elbow directing flow of coolant in downcomer
Inventor: FREI GERHARD DIPL ING
IPC: G21C15/18
Filed: 1990-10-09
Abstract: Emergency cooling water is fed in the reflux space of the pressure vessel of a pressurised water reactor in case of a loss-of-coolant accident, using as a flow guide element an elbow at the end of an emergency feeder circuit.  The end piece of the elbow points downward in the downcomer and can be convergent in shape. The pressure vessel (1) of a PWR has a "downcomer" (4) in the shape of a hollow cylinder between the pressure vessel wall (2) and the outer wall (3) of the core tank.  The main coolant inflow and outflow (6) pipes terminate in the downcomer.  If a crack occurs at the spot (10), emergncy coolant (11) is directed by elbows (12) at the end of the emergency circuit in a downward direction (f2) in the downcomer. ADVANTAGE - This prevents or minimises the cooling water loss both during the sudden pressure relief, when the main cooling pipe breaks, and during a core flooding phase.

Title: Wet discharge of ash from pressure-type coal gasifier -  through sluice with two compartments in economical, clean and automated process
Inventor: SKODDOW REINHARD
IPC: C10J3/52
Filed: 1990-10-16
Abstract: The sluice is divided into a dry compartment filled with water. The two compartments are divided, gastight from each other, by a shut-off device. After a differential pressure above 0.01 Mpa between the two compartments has been set, the shut-off device, assisted by pressure, opens and after complete quenching of the ash under pressure, the pressure is released. Some variants are claimed, including the release of pressure being timed to occur with a delay depending on ash grain-size. USE/ADVANTAGE - Ash removal by earlier methods, both dry and wet, has drawbacks overcome by this method, which uses little energy, is mechanically simple, can be automated, and provides easy removal of ash/water mixtures without dust and steam problems.

Patent DE-4101630-A1 (DE)
Inventor: BAUMEISTER JOACHIM DIPL PHYS
IPC: C22C1/08
Filed: 1991-01-21
Abstract: A process for making foamed metal bodies is described, in which a mixture (17) of a metal powder (15) and a gas-evolving blowing agent powder (16) is thermocompacted to form a semi-finished product (19), at a temperature at which the bond of the metal powder particles predominantly takes place by diffusion and at a pressure which is high enough to prevent the decomposition of the blowing agent, in such a way that the metal particles are in a solid bond with one another and represent a gas-tight seal for the gas particles of the blowing agent. The foamable metal body may also be produced by rolling. Furthermore, use of the foamable metal body (19) thus produced for making a porous metal body (21) is proposed.

Patent DE-4129208-A1 (DE)
Inventor: DOERR ALBRECHT DIPL ING
IPC: E03F5/10
Filed: 1991-09-03
Abstract: The invention relates to a process for preventing wrongly directed flows out of a rainwater channel (2) from being introduced into a receiving channel. The process is characterised in that the wrongly directed flows out of the rainwater channel (2) are transferred into a waste-water channel (4). The wrongly directed flows thus do not pass into the receiving channel but are transferred to the waste-water channel (4) connected to the sewage-treatment installation. An installation for carrying out the process has a rainwater channel (2) and a waste-water channel (4) and, furthermore, a connecting line (5) therebetween having a flow slope towards the waste-water channel. A sill (18) for channelling liquid away into the connecting line is arranged in the rainwater channel, and a regulator (20) regulates the throughflow through the connecting line (5). When the water in the rainwater channel (2) exceeds a defined level, the regulator (20) blocks off said channel towards the waste-water channel (4) and opens it again when the water falls below said level. Instead of a regulator (20) a pump (34) may also be provided which conveys the liquid from the rainwater channel (2) to the waste-water channel (4).   <IMAGE>

IPC: G06F17/28
Filed: 1992-09-28
Abstract: In business communication via international communication networks, texts are to be transmitted in future by a text written in a global standard language. This means that an information written in a source language is not translated into a target language in the country of origin and is then sent to the respective destination country but that the information written in the source language is first translated into a language-independent global standard language and is only translated from the global standard language into the target language in the destination country. This greatly reduces the number of automatic translation programs in the individual countries. <IMAGE>
