Abstract: A B S T R A C T      An improved clamp for nonmetallic rope has a plug formed with an annular collar at one end and a plurality of tapered segments formed integrally with the collar and extending outward-ly therefrom.  The tapered segments are separated by axially extending slots.  The plug has an axial bore defined by a serrated cylindrical surface to increase the gripping effect on a rope telescopically inserted into the bore.  The plug is teles-copically inserted into the tapered bore of an outer sleeve which compresses the tapered segments of the plug against the rope. The length of the plug is at least ten times greater than the diameter of its bore, which in combination with the annular collar, provides an increased clamping pressure between the serrated surfaces of the tapered segments and the rope throughout the length of the plug.  The outer tapered surfaces of the plug segments and the internal bore of the sleeve has a low friction, corrosion resistant coating applied thereto whereby the axial component of the wedging force between the plug and sleeve will be less than the axial component of the friction force between the rope and plug bore preventing slipping of the rope from within the plug bore.  The angle of taper of the plug is proximately 4° or less and is equal to or greater than the taper of the sleeve bore.

Abstract: Combined Starting/Generating System and Method Abstract A power conversion system for converting be-tween electric and motive power may be utilized either in a generating mode to generate electric power from motive power supplied by a prime mover or in a starting mode wherein motive power is developed by the power conversion system from electrical power and is supplied through a torque converter to the prime mover to start same.  The power conversion system includes a main generator,  an exciter and a permanent magnet generator, or PMG, which together comprise a brushless alternator.  When operated in the starting mode, power is supplied to the PMG to cause it to act as a motor and thereby drive a rotor which is common to the PMG, exciter and main generator.          Once a predetermined operating condition of the generator is attained, the main generator is supplied power from a motor control to cause the generator to act as a syn-chronous motor and the power supply to the PMG is discon-nected.  The torque converter is then commanded to trans-fer motive power from the generator to the prime mover to start same.

Abstract: ABSTRACT OF THE DISCLOSURE To limit the exposure of personnel  to  radio-activity within the channel head of a steam generator of-a nuclear-reactor plant a cartridge sleeve-blank loader for automatically sleeving a plurality of tubes without the intervention  of  personnel  is  provided.   The  cartridge loader includes a turret or drum which carries a plurality of sleeve blanks around its periphery.  A lifter engages the bottom of each sleeve bank in its turn at a sleeve insertion position of the turret and inserts the sleeve blank into a tube.  Successive sleeve blanks are indexed to the insertion position for insertion into tubes.  The sleeve blanks are slightly bowed or curved so that when a sleeve blank is inserted as a sleeve into a tube,  the sleeve, since the tube is linear, exerts a restoring force on the wall of a tube which holds the sleeve in the tube when  the  lifter is retracted.  In inserting the sleeve blank, the lifter moves at a low speed until the leading end of the sleeve enters a tube.  Then the speed of inser-tion is increased.  The turret is readily removable from the sleeve loader by use of a unique handle assembly so that any empty turret can be removed in a short time.  In the practice of the invention, a loaded cartridge sleeve-blank loader is loaded ready for insertion outside of the channel head.  Once all the sleeve blanks on a turret are inserted,  an operator enters the manway of the channel head and removes the unloaded turret.  The loaded turret is handed to him and he inserts it.  The replacing opera-tion  can be  accomplished  by exposing the  operator to radiation for no more than about 75 seconds.

Abstract: LIQUID FLOW CONTROLLER HAVING PRESSURE BALANCED PISTON FOR DELIVERING CONSTANT FLOW                ABSTRACT OF THE DISCLOSURE         A  small,  lightweight,  simple,   and   highly reliable  flow  controller (2) utilizing two moving parts (6, 48), for apportioning inlet  fluid  flow  between  an orifice outlet (26, 16) and inlet.  Constant outlet flow over a substantial  inlet  flow  and  pressure  range  is achieved  through the use of a flow balanced flow control piston (6) reciprocating internally  of  a  housing  (4). The  balanced piston is biased to a predetermined propor-tioning range through an internal spring (48).  The  unit is  normally operated with inlet port and outlet pressure sensing port in  fluid  communication  with  an  external orifice  (24).  A bypass port (14) communicating with the controller inlet  adjacent  the  control  piston  returns excess  fluid  to  the  reservoir  (22) of a pumped fluid system.  Increases in inlet flow  to  the  regulator/ori-fice  combination act to adjust the balanced piston posi-tion and initiate or increase  flow  across  an  integral piston/seat  control  orifice.   The downstream or outlet pressure of the external orifice is sensed  by  an  equal piston  area  distal  the cylinder seat and/or inlet side of the piston.  A damping piston (50)  abuts  said  inlet pressure  sensing portion of the piston in order to mini-mize transient piston motion or chatter.
