Following the fabrication, the impeller is finished and metallized.

Abstract: A method of restoring the shroud of a turbine blade which has become worn, and particularly that edge of the shroud in the vicinity of what is commonly known as the Z-notch, which comprises the steps of grinding down the shroud in the vicinity of said notch to an accurately predetermined dimension with respect to the original geometry of the shroud, placing the blade in a fixture having a masking member with a slot in it, such that the Z-notch of the blade is disposed substantially in alignment with the slot, and depositing, by means of a plasma spray, a metal alloy onto the edge in an amount just sufficient to build up the same essentially to its original dimension. Following the plasma spraying, the built-up edge is sintered at a temperature on the order of 1900.degree. F. or more, to more firmly bond the built-up layer to the base metal. The blade is then cooled.

Abstract: A process is disclosed for the manufacture of solid electrolytic capacitors wherein sintered anode elements with their anode wires are attached to a clamping fixture. In a further step a notch is formed in the anode wires. After bending of the anode wires the anode input wires which are held in an additional fixture are welded on in overlapping fashion. The notch acts as a designed fracturing or breaking point for the final separation of the capacitor elements. It is expedient to design the anode input wires to have a section expanded to form a roof like shovel.

Abstract: A fixture useful both to receive and position parts assembled for brazing and to hold the assembled parts during the brazing process. Part locators in the fixture position the parts during assembly or loading, and remain attached to the fixture during brazing. The locators are influenced to maintain an engagement with assembled parts but are able to yield in controlled directions under expansion resulting from the heat of brazing. The result is to obviate distortion in the brazed article. Locators have a linked relationship with relatively fixed support members, and are inherently self aligning in a vertical sense for uniform contact with the parts.

Abstract: An extraoral force-reaction device engageable with the wearer's head and/or neck, such as a headcap or a neckband, is connected to an intraoral force-applying device, such as molar bands, by force-producing means, such as springs. Snapback of the force-applying means is restricted by limiting the normal range of movement of the force-applying elements and such snapback is controlled in response to relative movement of the intraoral means and the extraoral force-reaction means away from each other beyond a predetermined maximum limit, or in response to stressing of the force producing means beyond a predetermined maximum degree of force exerted by the force producing means. Snapback control may be effected by latching of a limit latch to prevent or limit return movement of the force-reaction device and the force-applying device, or disconnectible means can be disconnected to interrupt the application of primary force to the intraoral means and reaction force to the head or neck engageable means.

Abstract: An automatic trap comprising an outer cage and a drum-shaped inner cage rotatably disposed about an axle within the outer cage. The outer cage has an outer opening which is, in the operative position of the trap, aligned with an inner opening formed in the inner cage to permit entry of a small animal into the inner cage. Within the inner cage there is pivotally and non-rotatably disposed a treadle means on the axle.
