[Also in Division F1] The felts 16, 34 utilized to press a paper web 14 against heated drier rolls 10, 11, 12, 31, 32, 33 in the drier section of a paper-making machine have at least one Coanda nozzle so positioned adjacent thereto that either the flow of gas induced by the nozzle, e.g. nozzle 28, will originate in the mass of gas adjacent the same surface of the felt as the nozzle and will converge with the belt to pass therethrough, or, the flow induced by the nozzle, e.g. nozzle 30, will originate in the gas adjacent the opposite side of the felt from the nozzle, will pass through the felt and diverge from its surface at an acute angle to its direction of travel into the mass of gas adjacent the same surface of the felt as the nozzle. Coanda nozzles may be positioned in opposed pairs on opposite sides of the felt to increase the flow of gas through the felt. The felt may be of synthetic polymeric material substantially physically and chemically stable at elevated temperatures.

Abstract: 1,226,919. Fuel elements. SNAMPROGETTI S.p.A. 23 Sept., 1969 [24 Sept., 1968], No. 46856/69. Heading G6C. A longitudinally extending fuel element includes in one end portion a member engageable with a grid of a nuclear reactor so as to lock the fuel element in the grid, and a longitudinally displaceable member which extends from this end portion to the other end portion of the fuel element, which is capable of actuating, either directly or indirectly, the engageable member and which is accessible at the other end portion. As shown in Fig. 1, a cylindrical sleeve 3 of a reactor grid formed by upper and lower horizontal members 1, 2 accommodates the lower end of a fuel element 4, this lower end comprising a hollow cylindrical member 9 inside which is a piston 10 provided with a slot 11 down one side into which extends a peg 12 fixed in the member 9 to prevent rotation of the piston 10. A rod 13 connected to the piston 10 passes through the upper part 14 of the member 9 and through the main body 8 of the fuel element 4, terminating in a ring 15 attached by spokes 16 to a cage 17 capable of limited vertical displacement in the upper region 18 of the fuel element. A spring 20 acts between the upper part 14 of the member 9 and a flange 21 on the rod 13. An annular groove 22 in the sleeve 3 can accommodate half of each of three spheres 23 displaceable along, and partially accommodatable in, three apertures 24 in the member 9. The lower parts of piston 10 also has an annular groove 25 positioned so that when the fuel element is in the locked position (as shown), it lies below the apertures 24 in the member 9. During loading and unloading of the fuel element, a hook (not shown) pulls upwardly on the ring 15 so that the cage 17 is at its upward limit of travel. This has the effect of moving the piston 10 upwards against the action of the spring 20 until the groove 25 is opposite the apertures 24 and each of the spheres 23 is accommodated partially in one of the apertures 24 and partially in the groove 25. The apertures 24 are provided with a slight taper towards their radially outer end to prevent the spheres 23 from falling out. On lowering the ring 15, the spheres 23 are squeezed out of the groove 25 and into the groove 22, thus locking the fuel element in relation to the sleeve 3. In order to remove the fuel element from the grid, one has only to pull upon the ring 15 so that the mechanism becomes unlocked, and, whilst maintaining the pull on ring 15, withdraw the fuel element.
