  • Patent number: 6419319
    Abstract: A wheel device and a chair equipped with the same which do not require replacement of a conventional retractable wheel, but instead enable the wheel to be placed in the operating state at all times, as required. The wheel device comprises a wheel and a holder member for holding the wheel. An urging member is arranged between the wheel and the holder member to constantly urge the wheel to be projected in an operable position. A retraction permitting member is adapted to permit the wheel to be retracted while overcoming the urging force of the urging member when a load is exerted in the direction of gravity on a member on which the wheel is mounted. The retraction permitting member includes a setting mechanism for setting the wheel to be in an un-retractable state. The chair is equipped with the wheel devices mounted to a leg portion thereof.

  • Patent number: 6419005
    Abstract: A mold cassette and method for continuously casting thin slabs. The cassette comprises a trough including a pair of vertically disposed, opposed broad walls and a pair of opposed narrow walls. The trough has an entry end for receiving molten material and an exit end for dispensing the material. The narrow walls are generally wider at the entry end than the exit end and are adapted for sealing engagement with the broad walls so as to prevent leakage of the material therebetween. At least one of the narrow walls is oriented at a selected tilt and adjustable at the tilt for changing the width of the slab during casting. Back edges of at least one of the adjustable narrow walls are relieved a region corresponding generally to the transition zone of the trough. This allows positioning of the narrow wall in a generally less than vertical plane during casting while maintaining the broad and narrow walls in sealing engagement with one another.

  • Patent number: 6418639
    Abstract: The invention concerns a method and a device in the dryer section of a paper/board machine. In the dryer section a normal single-wire draw is applied at least partly, in which method the web (W) is passed through the dryer group on support of a drying wire (H). The drying wire (H) presses the web (W) on the drying cylinders (Kn, Kn+1 . . . ) against the heated cylinder faces, and on the reversing cylinders or rolls (Sn, Sn+1 . . . ) between the drying cylinders (10) the web (W) remains at the side of the outside curve. There is one integrated device, through which a support suction and/or blowing is produced in order to improve the runability of the web (W) and to keep the web (W) in contact with the face of the wire, and through which same device, additionally, impingement blowing is produced in order to dry the web (W) and/or to control its tendency of curling.

  • Patent number: 6413498
    Abstract: Together with other accessory products, includes a mixture of ion-exchange resins, cationic and anionic, charged with Ca2+, F− and PO43− ions, in an approximate molar ratio of 2:1:1, respectively. Particularly preferred is a material in which the resins also have a charge of Zn2+ ions representing a proportion of less than 1%, preferably close to 0.2% of the dry weight of the resin. The preferred resins are those whose base is cross-linked polystyrene with 2-14% divinylbenzene. The material is useful as first filler in the treatment of caries, especially deep caries, leading to remineralization of the dentin with a composition very close to the original composition, together with high microhardness. It is also useful as a component of dentifrice products such as pastes, elixirs and dental floss.
