Abstract: A plug assembly for plugging the flow hole of a core support barrel employs an offset arm for securing the plug to the core support barrel above the flow hole and the adjacent thermal shield. The disclosed embodiments do not require the cutting of an access opening through the thermal shield.

Abstract: A golf towel set is adapted for attachment to a golf bag or other article. The golf towel has a main towel and an accessory towel. The accessory towel is releasably attached to the main towel. A fastener can attach the main towel to the golf bag or other article.

Abstract: 1,1,1-trifluoro-2-propene compounds which are useful in preparation of insecticidal, acaricidal and nematicidal arylpyrrole compounds are described. A method for the preparation of 1,1,1-trifluoro-2-propene compounds is presented.

Abstract: A bolt insert 24 with special bolt 50 provides a fastening method to secure hard metal nuclear reactor parts 12, 14, 16 provided with aligned square EDM produced openings 18, 20, 22. The insert is an elongated square internally threaded member with slots 34 defining flexing fingers 36. Fingers 36 have work engaging shoulders 42. Stop means tabs 28 at the bolt head end prevent overinsertion of the square insert 24 during the operation of pushing it into aligned square holes 18, 20, 22. Internal threads 32 of insert 24 mate with bolt threads 60 during torquing on bolt head 52 to advance bolt 50, which has tapered end 56 and pilot portion 58, to cam fingers 36 into holding position. Couterbores 30 receive stop means tabs 28 such that bolt head 52 does not bottom on insert 24. The method of producing fastening 10 removes the need for accurate threading operations on irradiated parts in the remote field.

Abstract: A laminar diaphragm (16) for use in a pressure transducer (10) comprised of two or more layers (50, 52, 54). The pressure boundary membrane (50) free of machining defects is supported by one or more support members (52, 54) having a fluid passage therethrough (56, 58). The support members (52, 54) are hermetically sealed around the periphery of fluid passages (56, 58) to the pressure boundary membrane (50) such that when the laminar diaphragm (16) is sealed in the pressure transducer (10) deflection of the pressure boundary membrane (50) within the regions of fluid passage (56, 58) in support members (50, 52) accurately indicates pressure.

Abstract: An improvement in fluid pressure transducers having a housing with oppositely facing magnetic blocks (12,14) that form a sealed chamber (20) in which a magnetically permeable diaphragm (24) is disposed for magnetic coupling with electromagnetic coils (30) mounted within the blocks. The coil is mounted on an elongated plug (34) and covered by a non-magnetic, unitary metal cap (36) that is flexibly sealed between the chamber and the coil. The cap has a generally cup-like inner portion (48) for covering the coil and a flat rim portion (46) that is sealingly (58) secured between the mounting plug and shoulder means (50,60) within the block.

Abstract: A fuel assembly having a lower end fitting and a spidered actuating rod interacting therewith for holding the assembly down on the core support stand against the upward flow of coolant. Locking means and bracing means for interacting with projections on the support stand are carried by the lower end fitting and are actuated by the movement of the actuating rod operated from above the top of the assembly. The locking means include weak springs mounted near some but not all of the end fitting posts, for engaging the support stand. Stiff springs are mounted internal to the other posts, for uring the posts against adjacent support stand projections to provide a bracing for the locking means as the spider portion of the actuating rod presses against the locking spring. The angle and spring rate per unit length of the bracing spring are preset to assure a fairly constant locking force during the life of the assembly.

Abstract: A feed control system for a plurality of packaging machines is provided wherein the overall supply to the machines is controlled in accordance with total demand. A pulse is produced by each machine after a filling and sealing operation is completed and a weight constant multiplier is employed to multiply this pulse by a weight constant associated with the package (the number of grams or ounces contained in the package). The outputs of all of the weight constant multipliers are connected to a parallel to series converter which produces a signal in the form of a pulse train representative of the total weight requirements of all packaging machines per unit time. This signal is converted into a corresponding voltage level which is utilized by a storage conveyor motor controller to control the overall feed rate to the machines.
