Title: Process and device for recovering raw materials from waste and residues
IPC: B01D53/46
Filed: 1998-04-28
Abstract: A process is disclosed for recovering raw materials, in particular heavy metals such as chromium, zinc, copper, lead, or nickel, by separation from waste and residues, wherein a liquid or viscous starting mixture and/or a starting mixture composed of crushed or ground components is first prepared. The invention is characterized in that the raw materials are separated by a thermochemical treatment. The liquid, viscous and/or solid starting mixture is first mixed with additives, depending on its composition, then subjected to a thermal treatment in an oven. The atmosphere in the oven flows through the starting mixture and the suspended materials thus generated as flakes or dust are conveyed out of the oven through a filter installation with several stages in which they are separated from the waste gas. The first filter is designed as a hot filter, after which the waste gas is cooled and after flowing through at least a second filter, pre-heated and then burnt at a high temperature. The process of the invention may be used, for example, to recover chromium (III) oxide from chromium-containing residues or zinc oxide from zinc-containing residues. Formation of chromium (III) oxide from chlorine-containing wastes occurs by formation and decomposition of chromyl chloride. Additives suitable for use in the invention may include those that comprise aluminum, aluminum oxide, iron, iron oxide, chlorine-containing material, sulfur-containing, milled plastics, granulated plastics, peroxides, silicon oxide, magnesium oxide or combinations thereof.

Title: High-voltage cable as high voltage decoupling for use with marx generator
IPC: H03K3/537
Filed: 2006-10-18
Abstract: In order to decouple the low-voltage charging source and its electrical drive from the high voltage which occurs in a Marx generator when the capacitor bank is switched from parallel connection to series connection, the high-voltage cable which is used on the output side and in which the conductive core is surrounded by a semiconductor for potential matching is also used on the input side, but for high-voltage decoupling after removal of the current-carrying core.

Title: Ink flying recording method and its device
Inventor: SEKIYA TAKURO
IPC: B41J2/01
Filed: 1990-04-16
Abstract: PURPOSE:To obtain stabilized ink flying by enabling high quality printing to be performed under a state without dripping of an ink drop by a method wherein ink is made to fly upward from an ink liquid surface, and the flying ink is made to stick onto a recording part of a material to be recorded positioned above from the ink liquid surface. CONSTITUTION:All areas of a passage are filled by ink 19, and each heater part 9 is also covered by the ink 19. When each heating element layer 14 is electrified individually according to image information, a bubble is generated in ink liquid on the heated heating element layer 14. The ink 19 flies in a direction almost vertical to a surface of a heater part by driving force of this bubble. A recording head 1 is used in a positional relation wherein an ink flying direction is upward below recording paper 22 as a material to be recorded. By arranging the ink liquid surface of the recording head 1 upward thus, dripping of a flying ink drop is not generated, and high quality printing can be carried out. Further, fluctuation in height of the ink liquid surface due to a difference in water head is less, and stabilized ink flying can be obtained.

IPC: H03M1/68
Filed: 1980-07-21
Abstract: PURPOSE:To reduce the settling during a high bit, by using two D/A converters having a small number of bits. CONSTITUTION:When the logical signal showing the prescribed value is applied to an input terminal 11 of a D/A converting circuit 12 of n1 bits, the output signal corresponding to the input signal is produced at an output terminal 13 to be applied to the input terminal at one side of an analog adder 15. Then the logical signal showing the prescribed value is applied to the other input terminal 21 of a D/A converting circuit 22 of n1 bits, and thus the output signal corresponding to the input signal is produced at an output terminal 23. This output signal is applied to the other input terminal of the adder 15 after the attenuation carried out through an attenuator 24. The ratio of attenuation of the attenuator 24 is set at a prescribed value according to the conversion code. As a result, the output signal corresponding to a D/A converter of n1+n2 bits can be produced at an output terminal 16 of the adder 15.
