Abstract

A two-direction motion bearing which is incorporated in a refueling nuclear fuel element trsnsfer tool assembly is described. A plurality of bi- directional bearing assembliesare fixed equi-distantly about the circumference of the transfer tool assembly to provide the tool assembly with a bearing surface- for both axial and rotational motion. Each bi-directional bearing assembly contains a plurality of circumferentially bulged rollers mounted in a unique arrangement which will provide a bearing surface for rotational movement of the tool assembly within a bore. The bi-direc tional bearing assembly itself is capable of rational motion and thus provides for longitudinal movement of the tool assembly.

Sync-ring assembly for a gas turbine engine exhaust nozzle

Patent Barcza, W

A sync-ring assembly is described for selectively positioning divergent flap of a gas turbine engine exhaust nozzle relative to the exhaust nozzle's case, the nozzle having a centerline defined there through, the assembly comprising: a sync-ring pivotably connected to the divergent flaps by a plurality of positioning strut assemblies, the sync-ring having a first surface and a second surface radially outward of the first surface relative to the centerline, the second surface is semi-spherical, a plurality of shaft bores equally spaced about the circumference of the sync-ring, each shaft bore extending through the sync-ring between the first surface and themore »« less
Drill-bit with full offset cutter bodies

Patent Frear, L

A rotary drag drill bit is seen wherein cutter bodies are rotatively connected to a main body structure at a fully offset position. The fully offset position is defined by a rotational axis of each cutter body, a longitudinal axis of the drill bit and end support points or positions of the cutter bodies. The rotational axes of the cutter bodies are perpendicular to the longitudinal axis of the drill bit. The end supports of the cutter body are each equal distance from any point on the longitudinal axis of the drill bit. The cutter bodies of essentially ellipsoidal configuration,more »« less
Hydraulic stabilizer for bore hole tool

Patent Lynde, G; Foster, B

This patent decribes an apparatus for stabilizing a tubular string within a casing in a well bore; a cylindrical tubular mandrel adjacent an end of the string; a pair of sleeve-like carriers mounted on the mandrel in longitudinally spaced relation to form upper and lower carriers, one of the carriers being mounted for sliding movement along the mandrel toward and away from the other carriers; each of the carriers including a body secured to the mandrel for rotation therewith, a housing mounted on the body, and bearing means between the body and housing permitting relative rotation therebetween; a plurality ofmore »« less
Wireline hydraulic retrieving tool

Patent Obrejanu, M; Weiler, D

A wireline retrieval tool is described for retrieving objects stuck in the interior of a tubing string in a well bore comprising an assembly adapted to be connected to and lowered on a wireline through the interior of a tubing string, the assembling comprising: (a) upper connecting means for connecting the assembly to the wireline; (b) lower connecting means for engaging a wireline pulling tool adapted to engage the object; (c) a fluid motor powered by pressurized fluid supplied by a hydraulic pump driven by an electric motor; (d) an electrical subsystem for supplying electricity; (e) an axially extending mandrelmore »« less
Intermittently rotatable down hole drilling tool

Patent Walter, B

In a down hole drilling tool a closed valve is operatively moved downwards by pressurized drilling mud pumped down the drill string, the valve when it attains its lower position being opened and being returned under the influence of a spring or other upwardly urging means acting on the valve to its upper position at which the valve is closed thereby to complete the cycle of operations. The valve is so continuously coupled to a torque member that the downward movement of the valve causes turning of the torque member in one direction, and the upward movement of the valvemore »« less
