Abstract: A device is disclosed for controlling the duration of an administration of a prescribed dose of dry powder to a user's lung when inhaling the powder by use of a dry powder inhaler (DPI). The present device controls the speed of a moving cassette (4) carrying medical powder doses to one by one be administered by the DPI to a user. Generally the dose is pre-metered and applied to the cassette in the form of a strip (31) or a series of spots of ready-prepared powder. The present device using the airbrake arrangement (22) prolongs the time during which the pre-metered powder dose is released to the inhalation air. Adjustment means of the airbrake arrangement (22) define leakage of air (36) and thereby motion speed of a spring-loaded cassette (4). During the motion of the cassette the powder dose is sucked from the prepared dose powder strip onto the cassette (4) by a nozzle (1) connected to a mouthpiece used for inhaling medical powder from the dry powder inhaler.

Abstract: A steam generator of the type used as a component of a pressurized-water power reactor installation, has a preheater to which feed water is supplied via a plenum chamber of extended length connecting with the preheater through a series of holes. The plenum chamber is supplied with feed water via the generator's feed-water inlet nozzle which injects a feed-water jet which impinges on an inner wall of the plenum chamber for deflection thereby and flow throughout the plenum chamber. This jet is surrounded by a perforated cylinder through which the deflected feed-water flow must pass for distribution throughout the plenum chamber, the effect being a more uniform distribution of the feed-water flow throughout the plenum chamber and a reduction in the flow resistance which otherwise prevails.

Abstract: 1448809 Welding by fusion WESTING- HOUSE ELECTRIC CORP 18 Sept 1974 [20 Sept 1973] 40723/74 Heading B3R [Also in Divisions G4-G6] Apparatus for the simultaneous pressurization and sealing of a nuclear fuel rod 10 comprises a housing 28 forming a gas chamber 68 for receiving at least the end of the rod 10 carrying a plug 14 with a sealable orifice 20, a rotatable stop member 70 having a conical opening 72 for receiving the conical end of the plug 14, and an inlet 78 for admitting pressurized gas, e.g. He at 450 p.s.i., to the gas chamber 68. A welding electrode 88 is secured in the wall of the housing 28 opposite the sealeable orifice 20 by means of a plug 90 and to obtain welding of the plug 14 in the fuel rod 10, and sealing of the orifice 20, an are is formed and a weld puddle then bridges the circumferential line formed at the junction of the fuel rod 10 and the plug 14 and the orifice 20. The electrode 88 is insulated by a p.t.f.e. insert 92 which is crimped tightly against the electrode to prevent high pressure (e.g. He) from escaping from the chamber 68. During the welding operation, the fuel rod 10 is rotated relative to the stationary electrode 88. A rotatable sleeve 36 is mounted for rotation in a bore 30 of the housing 28 on a pair of bearings 38, while a push rod 40 positioned in the sleeve 36 is provided with enlarged end faces 42, 44, the face 44 engaging a ram 45 located in the end of sleeve 36. A collet holder 48 has a bore 50 merging into a conical opening formed by diverging walls 52 and a collet 54 is positioned within the conical walls 52, the diameters being such that the fuel rod 10 may be inserted through the central openings in the collet holder 48, collet 54 and ram 45. Rotatable sleeve 36 is keyed to push rod 40 and ram 45 to permit rotation of these elements as a single entity via a pulley 94 and a motorized belt drive (not shown). Pneumatic or hydraulic cylinders 64 each contain a reciprocating piston connected to a backing plate 62 through connecting rods 66 such that as the pistons are moved to the right as shown in Fig. 3, the backing plate 62 engages a flange 58 on the collet holder 48, forcing it to the right to cause the collet 54 to capture the fuel rod 10 and thus hold it securely. To preclude leakage from the gas chamber 68 along the surface of the fuel rod 10, a deformable urethane seal 82 having a central opening is positioned in the sleeve 36 and one end 86 of ram 45 contacts the seal 82.
