Abstract: The Assembly has a submerged root, turbine-wheel-blading configuration, and utilizes circumferentially oriented, buried, friction damping wires, and continuous, overlapping, tip shrouds to minimize vibratory response. The wires, in the presence of blade vibration, simultaneously rub on both the blades and surfaces of a recess in the wheel in which the blade roots are fixed. The continuous tip shrouding provides additional damping through shroud-to-shroud interface rubbing. The assembly has a stack of identical blades, obviating any need for relatively weak locking blades or pieces. The method defines the steps of forming a peripheral recess in a wheel, in which to secure root ends of blades, and setting the damping wires (or wire) therein prior to installing the blade root ends, and uniformly spacing-apart the blades after securing the same to the wheel.

Abstract: The method involves the disposition of a pair of walls in separated juxtaposition, to form a space therebetween, the walls having transverse, vane-cross-section shaped apertures formed therein; setting vanes in the apertures, across the space; filling the space with core material for solidification therein; and then separating the walls and vanes from each other after the material has solidified. The fixture provides a pair of walls so apertured, and a platform upon which, removably, to support the walls.

Abstract: In an embodiment of the invention, the valve comprises an apertured valve seat toward and from which a valving element is movably disposed, for occluding and exposing the aperture in the valve seat to fluid flow. An actuating rod is coupled to the valving element and is movable along an axis for effecting movement of the element relative to the seat, and supporting structure is provided to support the actuating rod for its axial movement. However, the supporting structure, too, is movable along the aforesaid axis. Consequently, axial movement of the supporting structure reduces the possibility that, when the actuating rod must be moved, to effect movement of the valving element, it will be found to be stuck (i.e., "frozen") due to contamination, accretion of particulate matter, etc.

Abstract: A machine for manually cutting glass, plastic and mat employs a head having a unique breaker assembly by which the break-out of scored plastic sheet is readily effected, and in which the pillar post for the cutting element is supported to provide a blade repositioning feature. The head also includes means for maintaining the cutting element in its extended position, particularly to enhance effectiveness for cutting fibrous or cellular mat, cardboard, and the like.

Abstract: An antiperspirant formulation containing an extract from the aloe vera plant that prevents irritation in most persons sensitive to the metallic salts in common use as antiperspirants. A basic formulation consists of a 50% aqueous metallic salt astringent solution of 85 parts by weight and the natural gel of aloe vera of 15 parts by weight. The preferred metallic salt is aluminum chlorohydroxide. The salt may be combined with various other anti-microbial agents, drying agents, fragrances and the like with aloe vera extracts either in the natural gel form or as aloe extract oil to provide formulations for manual or aerosol sprays, roll-ons, creams and the like. The antiperspirant of the invention permit use by most persons formerly unable to tolerate many antiperspirants due to irritation of the skin.

Abstract: The arrangement comprises a turbine wheel having semicircular buckets milled into the periphery thereof and a steam or gas-discharging nozzle operatively associated therewith, according to prior art practices, in which an improved, efficiency-enhancing ratio of bucket radius to nozzle width is set forth, defined and depicted.
