A method is disclosed for securing a repair sleeve within a tubular fluid conveying conduit. The sleeve is positioned within the tube so that it extends coextensive with a region of degraded tube wall and partially beyond the axial extremes of the degraded area. A radially outwardly directed force is then applied toa the tubular sleeve from within along a portion of the sleeve at each end, extending beyond the degraded area. The force is sufficient to cause outward plastic deformation of both th...

A core holding structure for molds and method of making same. A hollow bushing is locked within a mold so positioned with respect to a cavity in the mold that a rod-like core may be mounted on the bushing to provide a bore for hollow members such as spouts used in the continuous casting of metals. The bushing effects proper spacing of the core from the walls of the mold so that the wall thickness of the finished article is controlled. The mold may be made from a single member or it may be made f...

An incubator and method of transfer in such incubator in an analyzer, wherein a simple transfer mechanism is provided for moving a cuvette from one incubator ring to another adjacent one. The mechanism comprises a shuttle disposed above said rotors, said shuttle having an aperture sufficiently large as to receive, but not retain by friction, one of said vessels, a mechanism for moving the shuttle and its aperture to traverse from one ring to the other, and a pusher member and mechanism for movin...

A polyolefin lined tank consisting of a rigid polyolefin tank within a metallic tank wherein there is no adherence or bonding between the walls of the inner polyolefin tank and the outer metallic tank, but wherein a maximum of 0.04 inch clearance is obtained between the said walls. The polyolefin tank is formed in the metallic tank by a rotational molding technique wherein a high temperature paint or other suitable release agent is first applied to the inner walls of the metallic tank; the tank ...

A temperature control system for a forehearth, said forehearth for thermally conditioning molten glass to be fed to a glassware forming machine, and being divided into a plurality of zones. Each of the forehearth zones is provided with devices for monitoring the temperature of molten glass within the zone, and apparatus for selectively heating the glass. A microprocessor-based time sharing system controls the temperature of the plurality of zones, using adaptive control loops. Each zone is assig...

A capability for internal self-testing is provided for a test instrument in which data, in digital and in analog form, is sampled from various test points. A programmable delay generator is used to process some of the data and to provide strobes which control the data output and which control the sampling of data. This enables measurements to be made at a preselected time after the occurrence of a particular signal, thereby giving the system a capability of using the delay generator not only for...

A radio controlled vehicle within a sphere has two wheels touching the sphere at diametrically opposite points, with the mass of the body of the vehicle hanging underslung from the wheels; to preserve a constant length always fitting the sphere interior the wheel which steers has a steering axis substantially congruent with the sphere diameter on which the wheels touch the sphere; when confronted with an obstacle stopping roll of the sphere in a given direction, the vehicle climbs the interior w...
