Patent EP-0094529-A1 (EP)
Inventor: MILLER EDWARD HARRY
IPC: F01D11/02
Filed: 1983-04-28
Abstract: Labyrinth sealing apparatus is disclosed which is effective to prevent rotational instability in the rotor of a steam turbine wherein such instability is of the type induced by steam whirl within the labyrinth seals. In a preferred form, the apparatus includes a plurality of fixed, spaced-apart annular teeth (24, 27) surrounding the shaft of a steam turbine whereby each tooth has a radially inner edge in very close proximity to the rotor surface, and further includes a fixed circumferential row of spaced-apart flow directing vanes (36) encircling the rotor on the upstream side of the annular teeth. Each vane of the row extends radially inward to within very close proximity of a raised annular land (41) on the shaft surface just opposite the vane row. The row of flow directing vanes and the raised land cause substantially the entire quantity of steam which enters the seal to pass through the row of flow directing vanes. Steam flow within the seal is caused to have a retrograde component counter to the direction of shaft rotation. This produces stabilizing forces on the rotor to neutralize destabilizing forces.

Abstract: A gas laser device has an anode (3; 63; 73; 83) and a cathode arranged oppositely in a discharge tube (2). The cathode comprises a plurality of cathode members (4, 5; 50A-50F; 6OA-60F; 70A-70F; 84, 85) each having a predetermined discharge effective cathode surface and each being electrically isolated from others. A switching circuit (24; 24') selects the cathode member(s) used for a continuous wave oscillation and the cathode member(s) used for a pulsed oscillation. The total area of the discharge effective cathode surface(s) of the cathode member(s) used for the pulsed oscillation is selected to be smaller than, preferably ⅓ to ½ of that of the discharge effective cathode surface(s) of the cathode member(s) used for the continuous wave oscillation.

Abstract: An improved process for producing a methane-enriched gas wherein a hydrogen-deficient carbonaceous material is treated with a hydrogen-containing pyrolysis gas at an elevated temperature and pressure to produce a product gas mixture including methane, carbon monoxide and hydrogen. The improvement comprises passing the product gas mixture sequentially through a water-gas shift reaction zone and a gas separation zone to provide separate gas streams of methane and of a recycle gas comprising hydrogen, carbon monoxide and methane for recycle to the process. A controlled amount of steam also is provided which when combined with the recycle gas provides a pyrolysis gas for treatment of additional hydrogen-deficient carbonaceous material. The amount of steam used and the conditions within the water-gas shift reaction zone and gas separation zone are controlled to obtain a steady-state composition of pyrolysis gas which will comprise hydrogen as the principal constituent and a minor amount of carbon monoxide, steam and methane so that no external source of hydrogen is needed to supply the hydrogen requirements of the process. In accordance with a particularly preferred embodiment, conditions are controlled such that there also is produced a significant quantity of benzene as a valuable coproduct.

Abstract: Procédé amélioré de stockage et de récupération de données numériques. Des codes de détection d'erreurs sont utilisés dans l'art antérieur pour identifier des secteurs défaillants. Dans ce procédé amélioré, les secteurs sont recueillis en groupes et un secteur par groupe est réservé aux informations de corrections d'erreurs. Les informations dans ce secteur sont calculées de telle sorte que les informations dans tout secteur du groupe peuvent être calculées à partir des autres secteurs. Tout secteur défaillant peut ainsi être récupéré. Afin de réduire les probabilités de perdre deux secteurs du même groupe, les groupes sont répartis de manière qu'aucun groupe ne contienne deux secteurs adjacents.
