Abstract: ABSTRACT OF THE DISCLOSURE An improvement in an air-jet texturing chest is disclosed.  The chest is adapted to house an air jet used in the air-jet texturing of yarn and to contain water which is added to the yarn prior to its entry to the air jet and which is blown off the yarn by the air jet.  The chest has: a base adapted to contain a pool of water; an air jet posi-tioned part way up the chest; an air inlet connected to the air jet; a water inlet over the pool of water; an air vent near the top of the chest; a water drain in the base of the chest; a yarn inlet to the chest; a yarn exit from the chest; and guide means adapted to lead the yarn from the yarn inlet under the surface of the pool of water, up the chest to the air jet, through the air jet and to the yarn exit.  The improvement comprises a mini-pan which is adapted to contain the pool of water and which is positioned in the base of the chest away from the sides thereof.  The mini-pan is useful in preventing contamination of the air jet with oil deposits which may form in the pool of water and be picked up by the yarn.  The oil deposits may be formed from spin finish which together with some of the water is removed from the yarn by the air jet and which in the absence of the mini-pan (i.e. with the pool of water occupying the whole base of the chest) flows down the chest into the pool of water.

Abstract: Cascaded Fin Winding Machine Control and Method Abstract Apparatus and a method for controlling the operation of a fin winding machine.  Various motor drives are utilized to regulate the speed of rotation of a heat exchange tube upon which fin is wrapped, to regulate the speed of rotation of forming wheels for bending the fin to the appropriate configuration and to regulate the speed of rotation of slitter wheels for perforating the fin prior to bending.  Sensing means are provided for determining the length of the fin strip within various segments along a fin route such that the motor speeds are all adjusted to maintain the desired amount of fin strip.  Tension means are provided for maintaining constant tension of the fin strip regardless of the length of the fin strip in the appropriate segment.  The various sensing means are cascaded such that a change in speed of one motor may affect a change in speed of another motor.

Abstract: Abstract of the Disclosure The insulative stand-off is mounted on a frame and supports a heating coil.  In the preferred embodiment the coil loops engage retention surfaces inside the inverted T-shaped opening in the end of the stand-off.  The sides of the stand-off forming the opening have cam surfaces which squeeze adjacent central loops together during mounting while the loops adjacent the central loops are deflected to the outside of the stand-off.  When the central loops reach the crossbar of the T they spring apart to fix the coil.  Other embodiments are shown....all have retention surfaces generally parallel to the coil loops and transverse the coil axis.  Cam surfaces control access to the retention surfaces to deflect the loops as they are moved to the retention surfaces and the coil resiliency biases the loops into engage-ment with the retention surfaces when mounting is completed.

Abstract: Abstract A hydraulic setting tool for use with a packer having expan-dable anchor means for anchoring the packer in a well bore, a conduit to permit flow through the packer, and a slidable valve positioned in the conduit having an open lower position and a closed upper position.  Inner and outer tubular portions are telescopically interengaged with the inner portion receiving a slidable mandrel.  The tool conduit is connected to the inner sleeve with a shearable tension collar, the mandrel passing through the collar and into the conduit for engagement with the valve.  Annular pistons are provided between the inner and outer sleeves and between the mandrel and the inner sleeve.  A flapper valve is pivotally attached on one side to the inner sleeve for sealing the top of the mandrel.  Pressurization of the inner sleeve via tubing string from which the tool and the packer are suspended pressurizes the annular spaces beneath the pistons thus forcing the inner sleeve as well as the mandrel upwardly to set the tool.  Such upward movement of the inner sleeve breaks a seal at the lower end thereof to permit depressurization of the annu-lar space below the mandrel piston which forces the mandrel down-wardly.  A lock ring locks the mandrel in its lower position to permit further operation of the valve with the mandrel.

Abstract: ABSTRACT         A shock absorber has a rebound stop assembly.          The rebound stop assembly rests upon a shoulder fixed to a piston rod.  The rebound stop assembly includes an elasto-meric  ring  interposed  between  two  collars  forming  an annular chamber therebetween.  At the end of the rebound stroke of piston rod, the rebound stop assembly is axially compressed between the shoulder of piston rod and the rod guide until the elastomeric ring deforms to abut the inner wall of the working cylinder.   As  the elastomeric ring deforms,  the  annular  chamber decreases  in  volume.    A restrictive passage allows a restrictive  flow  of  fluid therefrom.   An additional chamber is formed which is in restrictive fluid communication through the passage with section of rebound chamber.   Further compression of the stop assembly decreases the volume of both chambers and causes restrictive fluid flow out therefrom through the passage into the section of rebound chamber.   The com-pression of the elastomeric ring and the restrictive fluid flow provides additional damping at the end of the rebound stroke.

Abstract: Abstract of the Disclosure A constant load and constant contact force snap-action switch having a normally-closed movable operate contact on a flipper blade which has a compression strip that snaps through an S-curvature to a reverse buckled state to trip the operate contact open.  The flipper blade is coupled through an insulating cap to the leaf spring mounted movable alarm contact to close the latter at the same time.  A return spring biased reset lever resets the operate contacts on depression down a first amount, opens the operate contact without closing the alarm contacts on depression down a second amount for stop purposes, and trips the operate contacts open on lifting upwards for test purposes.  On reset, lost motion in the coupling cap knocks the alarm contact open if welded.  A selector is wettable to select any of three functions for the reset lever, (1) reset-stop-test, (2) auto reset stop, or (3) reset test.
