Abstract: PCT No. PCT/EP97/01544 Sec. 371 Date Jul. 16, 1997 Sec. 102(e) Date Jul. 16, 1997 PCT Filed Mar. 26, 1997 PCT Pub. No. WO97/37062 PCT Pub. Date Oct. 9, 1997The invention relates to a method and device for the electrochemical treatment of electrically mutually insulated, electrically conductive areas on an item to be treated by means of a treatment liquid. Insulated, for example etched structures on circuit boards cannot be treated electrochemically with known methods since there exists no electrical connection to the bath current source from individual areas. According to the invention, this connection is produced by brushes which touch the structured surfaces to be treated with their electrically conductive and thin fibres. A large number of brushes which are arranged transversely to the direction of transportation take care of the fact that all the electrically conductive areas on the item to be treated which are arranged in an insulated manner from one another are contacted electrically at least one after another and that the achieved contact time is sufficiently long. Counter-electrodes, which may be also designed as movable brushes, are situated preferably between the brush electrodes. In electrochemical processes, in which metal is deposited, the brushes are deplated cyclically. For this purpose, various possible solutions are proposed.

Abstract: The arrangement has at least one disc stack and associated magazine with parallel threaded spindles arranged about the circumference of the discs and extending over the entire stack length so that the disc edges sit loosely in the thread paths. The discs are moved along the stack axis by spindle rotation to a desired position in which they are extracted by a manipulator and transported to a defined position. For a single stack design the spindles have a greater pitch and thread depth in a central region for a constant core dia. than in the input and output regions. For multi-stack arrangements the opposite applies, but in both cases the peak dia. is matched to the pitch.

Abstract: The invention relates to a method for producing [<15>O] butanol. The invention also relates to a device for implementing said method. According to the inventive method for producing [<15>O] butanol, a column containing an adsorbent is exposed to tri-n-butylborane, a gas containing [<15>O]O2 produced in a cyclotron is guided through the column, the reaction product is then hydrolyzed, the [<15>O]O2 obtained is purified and the solution containing the purified [<15>O]O2 is fed to a container. A plurality of columns containing the adsorbent is fixed on an exchangeable element and the exposure to tri-n-butylborane is carried out on the columns fixed on the element. The steps for conducting the inventive method can be carried out in a particularly quick and safe manner. The inventive device is particularly suitable for implementing said method. The device comprises a protective gas inlet, a container with water, an element for receiving a plurality of columns containing an adsorbent, a system for purifying the [<15>O]butanol obtained and a container for receiving the purified [<15>O]butanol. The device also includes a container with tri-n-butylborane. The element for receiving the columns containing an adsorbent can be exchanged and is arranged in such a way that it can be displaced. The method can be conducted with particularly good results when columns with adsorbent Sep-Pak Alumina N Plus cartridges are used, when purification of the [<15>O]butanol obtained is conducted using Sep-Pak C-18 Plus cartridges and when said cartridges are fixed on a disc-shaped element consisting of a top and a bottom part.

Abstract: FIELD: releasing energy from hydrogen atoms (molecules). SUBSTANCE: energy is released from hydrogen atoms (molecules) by encouraging transfer of electrons to lower quantum energy levels (with smaller radii of small and large half-axes) than energy level of main state due to providing energy holes or methods for releasing energy resonance-tuned with hydrogen energy emitted for encouraging these transfers. Energy holes and energy absorber are provided due to transfer of at least one electron between reacting substances including atoms, ions, molecules, as well as ion and molecule compounds. In one case energy hole includes transfer of t electrons from one or more electron-emitting substances to one or more other electron-emitting substances; subtracting total energy of ionization and/or of electron affinity of energy-absorbing substances from total energy of ionization and/or electron affinity of electron-emitting substances will give approximately m x 27.21 eV (m x 48/6) for reaction of atomic (molecular) hydrogen transfer to energy levels below main-state energy, where m and t are integer numbers. EFFECT: enhanced reliability of energy conversion. 58 cl, 16 dwg, 9 tbl
