Title: Apparatus for the sleeving of tubes in hostile  environments
Inventor: COOPER FRANK W JR
IPC: F22B37/02
Filed: 1984-10-01
Granted: 1988-08-16
Abstract: ABSTRACT OF THE DISCLOSURE         Sleeves inserted in the coolant conductors of a steam generator of a nuclear-reactor plant are rolled by remotely controlled apparatus minimizing the time which personnel must spend within the radioactive environment of the channel head of the steam generator.  A sleeve is rolled by a tube provided with rolls which are normally retracted and which, during a rolling operation, are extended into rolling engagement with the sleeve by a rotating tapered mandrel.  The mandrel advances into the tube rotating the rolls while progressively increasing the pressure between the rolls and the sleeve.  The sleeve is rolled near its upper end and also at its lower end in its region which is within the tube sheet by upper and lower rolling tools.  The tube carrying the rolls is moved into the sleeve by a remotely controlled drive.  The drive is a low voltage motor for the upper tool and a hydraulically driven piston for the lower tool.  When the tube reaches its uppermost position in contact with the tube sheet or the end of the sleeve in the coolant conductor the mandrel is automatically actuated, responsive to the actuation of a switch to move into the tube to extend the rolls in the tube into progressively increasing pressure engagement with the sleeve and also to rotate as it moves into the tube.  The translational drive for the mandrel is a low voltage electric motor for the upper tool and a pneumat-ically driven piston for the lower tool.  The rotational drive for both tools is a hydraulic motor.  That the desired upper rolling has been reached, is automatically determined by a thrust bearing on the mandrel which stops the advance of the mandrel into the tube at a proper diameter of the mandrel.  The lower rolling is stopped responsive to the reactive torque of the hydraulic motor and may also be stopped by timing.  In either case the three drives are reversed.  The mandrel, in a direction opposite to its motion during insertion, is retracted, the rolls are removed from engagement with the sleeve and the tube is moved out of the sleeve.

Abstract: ROTOR OF AC DYNAMOELECTRIC MACHINE WITH IMPROVED COOLING AND STABILITY            Abstract of the Disclosure A shaft of a high-speed AC dynamoelectric machine includes axially directed flutes which define lands upon which an aligned stack of annular laminations of magnetic steel are shrunk-fit.  The flutes concentrate contact forces generated by shrink-fitting in known positions and the non-contacting regions aligned with the flutes provide a small amount of resilience which permits thermal expansion of the rotor to occur without forcing a migration in the shrunk-fit contacting surfaces. The flutes may be used as axial ventilation holes whose effectiveness is enhanced by radially directed air flow channels communicating between the flutes and the outer surface of the rotor.  In rotors using laminations which include keyways therein, the fluted shaft provides sufficient keying of the laminations to the shaft so that a key may be omitted.  In order to avoid stacking of burrs in the laminations, succeeding groups of laminations are angularly indexed so that the effects of any recurring burrs are distributed about the circumference of the rotor and are thereby cancelled out.

Abstract: Abstract of the Disclosure An automatic shut off valve comprising a housing having a main inlet, an outlet, a user inlet and a user outlet.          A valve assembly is contained within the housing and is movable between an open and a closed position.  In its open position, the user inlet and outlet are fluidly connected in series with the main inlet and main outlet while, conversely, in its closed position, the valve assembly sealingly closes and isolates both the user inlet and outlet from the main inlet and main outlet.         A compression spring urges the valve assembly towards its closed position while a fluid flow rate greater than a pre-determined amount. into the user inlet retains the valve assembly in its open position.  Consequently, in the event of an interruption or blockage of the fluid flow between the user inlet and outlet, the compression spring snaps the valve assembly to its closed position thus isolating the inlet and outlet from the main inlet and terminating fluid flow through the shut off valve.  In the preferred form of the invention, a flow indicator provides an exteriorly visible indication of the flow rate through the shut off valve.

Abstract: Abstract An improvement is made in a color picture tube having a slit-type shadow mask mounted therein in spaced relation to a cathodoluminescent line screen.  For the mask, the spacing between adjacent aperture columns increases from center-to-edge as approximately the fourth power of the distance from the center.         Such fourth order spacing variation permits shaping of the shadow mask so that the contour of the mask along its major axis also varies as a function substantially of the fourth power of distance from the center of the mask.

Abstract: ABSTRACT A character generator in a receiver provides a character signal in raster scan form for display with a received video signal.  An oscillator, not synchronized with the horizontal synchronizing component of the video signal, supplies a clock signal to the generator for controlling timing of character elements.  A control unit provides a control signal representative of a time difference between the clock signal and the horizontal synchronizing component.  A delay unit, interposed in the clock signal path, selectively imparts delay to the clock signal in response to the control signal for reducing line-to-line variations in the timing of displayed character elements.

Abstract: Abstract of the Disclosure A timebase generator includes a transistor switch performing a sweep gate function, alternately providing a current path for retrace and then disconnecting such current path to allow generation of a time base ramp.  The bias current delivered to the switch is controlled to be at a high level for bringing about proper retrace, but at a low level at the beginning and ending of the time base sweep itself to prevent undesired transients and nonlinearity effects.  The low current is maintained from the end of the retrace period until the start of the following retrace period.  A baseline stabilizer loop comprises a transistor circuit for accurately predetermining the baseline reference wherein the emitter current of the transistor is controlled to a substantially constant value during operation for enhanced stability.  The undesirable effect produced by inherent capacitance of a semiconductor device current source used for charging the timebase generator timing capacitor is neutralized by means of a matching semiconductor device interposed between the timebase generator output and an input electrode of the first mentioned semiconductor device.
