Patent DE-4319828-A1 (DE)
Inventor: RAEHSE WILFRIED DR
IPC: F26B3/08
Filed: 1993-06-16
Abstract: The invention describes a process of at least substantially waste-air- and waste-gas-free drying of a water-containing material through the latter's direct contact, in a drying zone, with a circulating stream of a hot-gas mixture that contains superheated water vapor mixed with at least a second drying gas, in particular nitrogen and/or air, wherein the vaporized water is separated out and the preferably indirectly reheated hot gas mixture is directed back into the drying zone. The process is characterixed in that a portion of the gas stream of the first circuit sketched above is diverted after the drying zone, this partial stream is cooled to the point of at least partial condensation of its water content and is separated from the aqueous condensate, and the remaining gas stream (second circuit) is fed back into the circuit of the hot gas mixture. Thus, preferably at least a portion of this cooled gas stream is used as auxiliary agent in the further course of the drying process. The invention also pertains to the use of this modified drying process on any materials, but especially in the drying of temperature-sensitive goods with material temperatures under 100  DEG C.

Title: Process to alter neutron energy spectrum in a light water reactor - by use of trans=plutonium elements within energy spectrum altering rods that can be inserted into or withdrawn from core
Inventor: MILLOT JEAN-PAUL
IPC: G21C5/00
Filed: 1993-07-14
Abstract: A process for use in a light water moderated nuclear reactor, whereby trans plutonium elements, arising from re-processing of spent nuclear fuel are incorporated in rod bundles to alter the neutron energy spectrum of the reactor during its fuel cycle. They are used in the first phase of the fuel cycle when core reactivity is high and it is necessary to reduce the ratio of moderator to fissile fuel and hence to reduce the number of thermal neutrons by increasing the number of higher energy neutrons. The trans-plutonium elements are dispersed within oxide tablets of thorium or depleted uranium oxides, or zircalloy. These are assembled in rods which are inserted during the first phase of the fuel cycle and withdrawn above the reactor in the second cycle when reactivity is lower. USE/ADVANTAGE - The process provides a means of utilising trans-plutonium elements arising from re-processing, which would other wise have to be stored safely for long periods due to the elements by half-lines. The trans-plutonium elements actually shift the neutron energy spectrum to higher energies rather than just physically displacing the water moderator. The trans-plutonium elements undergo neutron induced decay to elements of shorter decay times and to some useful media or industrial isotopes.

Title: Mobile base station and antenna arrangement to provide radio coverage for a tunnel
Inventor: TURBAN KARL-ALBERT DIPL ING
IPC: H01Q21/28
Filed: 1993-10-16
Abstract: The provision of radio coverage for a tunnel poses particular problems if the radio field range within the tunnel is intended to be integrated within a cellular mobile radio network. A mobile base station (BTS) and an antenna arrangement to provide radio coverage for the tunnel are provided in such a way that a tunnel radio cell (TC) is formed which covers the entrance areas of the tunnel as well as the inside of the tunnel. For this purpose, the antenna arrangement comprises a plurality of antennas (AS, AL, AO) which feed the mobile base station in co-channel mode. For each of the antennas, the mobile base station contains an RF/IF stage and an AF stage common to all antennas. The transmit signals are generated there as digital broadband signals and the receive signals are superimposed. The mobile base station operates accordingly on the basis of the macrodiversity principle. The invention can be particularly advantageously used for the provision of radio coverage for railways within a radio link network.   <IMAGE>

Title: Measuring device for electromagnetic waves
Inventor: MATSUZAKI KAZUO
IPC: H01J17/14
Filed: 1994-07-08
Abstract: A measuring device for electromagnetic waves has one or more measuring cells, each of which contains an electron-emission arrangement (13, 14) having a cold cathode (13), an electron-capturing arrangement having an anode (15) arranged opposite the cold cathode (13) in a vacuum space (17), a magnetic-field-applying arrangement (18) for applying a magnetic field orthogonally to an electric field between the cathode and the anode in the vacuum space, and a sealing arrangement (16) for trapping a thinned gas in a vacuum space. The measurement is based on the amplification of the cyclotron resonance which occurs when the cyclotron frequency of the electrons emitted by the cathode and travelling to the cathode is identical with the frequency of an electromagnetic wave which is to be measured and whose electric field vector lies in the direction of the electric field between cathode and anode. This amplification becomes apparent in a steep rise of the anode current. Since the cyclotron frequency is proportional to the induction of the applied magnetic field, the change in the induction of one measuring cell and/or different induction of a multiplicity of measuring cells can result, for the measuring cell, in the state of the amplified cyclotron resonance and the wavelength to be measured can be determined with reference to the cyclotron frequency of this measuring cell. <IMAGE>

Title: Non=rigid double skinned helium filled airship
Inventor: SCHLENKER MARKUS
IPC: B64B1/04
Filed: 1994-07-20
Abstract: The airship is filled with helium at higher than atmospheric pressure, which keeps the airship's shape defined. Fins (16,18) provide an aerodynamic stability and an engine drive propeller (20) generates drive. Air sacks (22) inside the envelope (12) are connected by tubes (24) to the atmosphere, so that they can be either filled or vented on the ground. A second skin (26) lays over the main envelope. It has lengthways openings (30) along both sides. Multiple, adjustable length straps (36) join the upper and lower edges (32,34). The straps can be tightened with the buckles (38). Shortening the straps brings the opening's edges together and thus reduces the width and height of the envelope. Simultaneously releasing air from the airsacks prevents the internal gas pressure from rising, without having to vent helium gas.
