Patent EP-0303839-A1 (EP)
Inventor: GLADBACH KARL-HEINZ
IPC: F17C13/08
Filed: 1988-07-20
Abstract: Pressurised-gas bottles made of high-alloy chromium-nickel steels for the storage of ultra-pure gases are cryogenically worked to improve the strength properties. The foot ring normally welded to the bottom part of the pressurised-gas bottle in order to form the bottle foot, which bottom part consists of a cylindrical tube (1) and welded-on end (2), impairs the cryogenic working. Welding the foot ring to the bottom part after the cryogenic working would destroy the strength properties again. Therefore a detachable foot part (4) is attached to the bottom part of the pressurised-gas bottle. The foot part is preferably made of shock-proof plastic and is screwed on via a threaded stem (3) welded to the end. <IMAGE>

Abstract: A mixing element (18) for the mixing of farinaceous material, is arranged to rotate at different speeds during the development of the material. 
     The power developed by the motor is arranged to be constant throughout as the whole of mixing process and the speed of the rotating element is decreased as the resistance to its motion, provided by the developing farinaceous material, increases. This characteristic, which is required for minimum power wastage, may be effected by the sensing of the resistance provided by the developing material.

Abstract: An improved technique for forming silicon-­on insulator films for use in integrated circuits. The technique provides an improved encapsulation layer (4,5) to enable in a reproducible way the zone melt recrystallization of such films. The encapsulation layer consists of a first layer (4) of a doped SiO₂ (silicate glass) on which a further layer (5) of Si₃N₄ is deposited. The doped SiO₂ forms a fusible glassy material which is rendered semi-liquid and flows at the temperatures used in recrystallization. The softening of the encapsulation material accommodates volume expansion and eliminates the biaxial stresses in the layered structure. The Si₃N₄ layer adds mechanical strength to the SiO₂ layer and improves the wetting angle.

Abstract: The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station (MS₁, MS₂) is handed over from at least a first base station transmitter (B ma , B mb ) to at least a second base station transmitter (B na , B nb ). 
     In accordance with the invention, the same radio channel is used, if possible, before and after the handover for transmitting message information to the mobile station. If the same radio channel can be utilised, the handover takes place without the mobile station being informed beforehand of the handover by a special signal or order or the like. 
     In digital mobile radio systems with digital transmission of message information by digital modulation of the radio signals, the transmission is preferably started from a second base station transmitter before the transmission is terminated from a first base station transmitter. During a transmission time substantially the same message information is transmitted to the mobile station from both at least one first and one second base station transmitter.

Abstract: La présente invention décrit un moyen et un procédé permettant d'observer le spectre des infrarouges obtenu à partir de l'émission d'infrarouges de molécules excitées dans des échantillons étudiés (21). Dans l'intervalle de longueurs d'ondes allant de 1 à 5 microns, on a observé deux bandes d'émission forte avec un détecteur PbSe (24) lors de l'introduction de composés organiques dans une flamme d'hydrogène/air (21). La bande à 4,3 microns (2326 cm-1) était due à l'étirement asymétrique du dioxyde de carbone, alors que la bande à 2,7 microns était due à l'émission à la fois d'eau et de dioxyde de carbone. On a observé que l'émission de dioxyde de carbone à 4,3 microns était la plus intense à la pointe de la flamme (21) et qu'elle augmentait avec l'accroissement de la quantité du composé organique introduit dans la flamme (21). Pour une application chromatographique, on a utilisé un filtre optique pour isoler la bande d'émission de 4,3 microns.
