Abstract: Rotor blade and disk structures enabling the disassembly and reassembly of a single rotor blade are disclosed. The concepts are particularly suited to configurations employing interlocking mid-span shrouds which inhibit the withdrawal of a single blade from a disk.In one specific geometry the rotor blade root section (20) and the disk attachment slot (24) are contoured to provide increasing clearance between the bottom of the blade root section and the attachment slot as the blade is withdrawn axially from the slot. Rocking of the blade within the provided clearance enables withdrawal of the blade around the shroud segments (30,32) and airfoil sections (16) of the adjacent blades (12).

Abstract: A continuous line for chemical treatment and irradiation of a textile web has an irradiation station provided with an outer protective jacket which has elongated openings for passing through the upper and lower runs of the conveyor. The ray exit window in the range of the outer protective jacket is enclosed by an inner protective jacket defining openings for the upper run of the conveyor supporting the web. To reduce leakage, the inner openings are vertically offset relative to the openings in the outer jacket, and the chains in the upper and lower runs of the conveyor are enclosed in protective casings, of which the upper-run casing is provided with slots for guiding the web. Ray-screening means in the form of displaceable screening blocks are provided in the range of the inner and outer openings and are movable together with the guiding channels.

Abstract: A deformable support for a pressure plate blood processing centrifuge apparatus is described. A plate 50 is disposed adjacent a deformable support 10 having a recess for a flexible bag 8 in which blood is processed. Under the influence of centrifugal force the plate 50, which is disposed inwardly nearer the center of rotation than the bag 8, exerts a force against the support 10 and bag 8 and expels a separated blood component from the bag into a receiver container 6.The support 10 absorbs forces in the bag 8 thereby enabling the bag to be made of thin walled inexpensive material which would otherwise rupture under the separation forces. Yet the support 10 is sufficiently yielding to enable the pressure plate 50 to move and create an expelling force.

Abstract: A mixer comprising a conical mixing vat, tapering downward toward a material egress, and a motor-driven mixing worm which rotates on its axis and revolves within the mixing vat, the mixing worm having an upper region with a small screw pitch and, a lower region with a large pitch and a neutral conveyance zone between the upper and lower regions. In order to achieve a stable pattern of the junction formed by the neutral conveyance zone of the mixing worm between the upper and lower regions, which will be independent of the degree to which the mixer is filled, a mixing worm rotates around another mixing worm which is placed centrally in the upper region of the mixing vat along its longitudinal axis, this worm being of cylindrical shape along its length and extending into the conveyance neutral zone and with its exterior diameter nearly touching the other mixing worm.

Abstract: A two roll press machine for removing moisture from particulate organic material includes a stationary powered roll and a powered positionable roll journalled within a carriage slidably entrained on a machine base.
