Abstract: The invention relates to a screwdown device for adjusting the roll gap or rolling force in rolling stands. The screwdown device has two hydraulic screwdown cylinders (2) which act on both sides of a work roll (5) to be adjusted. The screwdown cylinders each have two or more piston faces, which can be supplied with pressure medium independently of one another, either individually, in any desired combination or all together. It is thereby possible to improve the control of the rolling force in the respective range in such a way that percentage fluctuations in the rolling force are minimised and, as a consequence, variations in the roughness and wall thickness are reduced to a non prejudicial level.

Abstract: In a method of transmitting digitally coded information in a television sound channel, the digitally coded information is inserted on an existing frequency-modulated RF sound carrier as a channel-coded signal above the television audio-frequency base spectrum in the base band. The modulation amplitude is selected so that disturbances during reproduction of the television sound are excluded in the receiver. The spectrum of the channel-coded signal is evenly distributed over the available frequency range using a pseudo-signal during modulation intervals. The clock frequency of the channel-coded signal is coupled with the line frequency.

Abstract: Dispositif de freinage de sortie facilement mobile faisant partie de, ou fonctionnant concurrement avec, un fournisseur de fil (13) comportant un corps de stockage du fil à position spatiale fixe, duquel un fil (11) peut être tiré, même à une vitesse élevée, en passant par un canal de sortie (10). Le système comprend un premier élément (9) disposé dans un logement et permettant, quand le système est en service, de tirer le fil au moyen d'une griffe de serrage de surface en le faisant passer sur un élément de contre support (15). Les éléments (9, 15) sont conçus de façon à assumer une fonction de nettoyage du fil dépendant de la rotation du fil pendant le tirage, tout en empêchant une accumulation considérable de fibres courtes, de particules, etc. dans les éléments. La mobilité du système est obtenue par le choix des composants en question. La mobilité permet un débit instantané et un retour instantané à l'effet de freinage/tensionnement préalable s'il y a un n÷ud dans le fil et/ou une réaction instantanée à une ou plusieurs commandes supplémentaires servant à modifier la force de freinage ou de tensionnement du système pendant un cycle de tirage de fil (cycle machine).

Abstract: Pour mettre à jour une donnée (D) dans une mémoire (20) sans risquer de perdre son ancienne valeur (D0) tandis que la nouvelle valeur (D1) n'aurait pu être complètement écrite, l'invention prévoit d'utiliser pour la mise à jour au moins deux emplacements mémoire (E0, E1), l'un dans lequel se trouve la valeur ancienne (D0) et l'autre dans lequel est écrite la nouvelle valeur (D1). Cette nouvelle valeur est vérifiée et un indicateur logique associé (b1) change d'état après que la valeur vérifiée ait été reconnue correcte en vue de la lecture. Si l'indicateur ne change pas d'état une opération de lecture peut aboutir à la lecture de l'ancienne valeur de la donnée, mais jamais à la lecture d'une valeur aberrante.

Abstract: This invention provides a process to convert linear alkenes such as butene-1 and butene-2 to methyl branched chain alkenes such as isobutylene using one dimensional, medium pore zeolite catalysts and similar type catalysts such as SAPO's and MeAPOS's. The pore size for the catalyst should be greater than 0.42 nm and less than 0.7 nm, preferably with a larger dimension of between 0.5 and 0.6 nm. This pore size allows the branched chain alkenes to form and diffuse out of the catalyst while reducing the formation of unwanted by-products, including dimers, trimers, aromatics and coke. This invention has been demonstrated with H-ferrierite, SAPO-11, and magnesium mordenite in a laboratory scale reactor. Selectivities ranging from about 50% to almost 100% were demonstrated for isobutylene formation using H-ferrierite, at temperatures ranging from about 340 DEG C to about 440 DEG C.
