Abstract: A yarn remnant removal system for flexible textile yarn tubes deflects the textile yarn tube inwardly in order to effectively reduce the tube circumference and loosen the yarn remnants wrapped thereon. The system provides for a tube receiver over which a textile yarn tube is placed and a deflection arm or blade which operates to engage and deflect the textile yarn tube inwardly while the tube rests on the tube receiver. Preferably, the tube receiver will include vacuum cups for providing a vacuum to engage a deflected portion of the textile yarn tube and to hold the textile yarn tube in an inwardly deflected state. The textile yarn tube remains deflected after the deflection arm is released. Multiple jets of air may be used to blow the yarn remnants from the textile yarn tube and the tube receiver may be rotated downwardly into a vertical position to further facilitate remnant removal.

Abstract: A system used to recycle remnant fiberglass that has been removed from bobbins by water jets. The fiberglass recycling system includes a conveyor system for transporting the fiberglass to a centrifuge which dewaters wetted fiberglass. A detector having photoelectric devices is positioned at a discharge end of the conveyor system to detect dimensions of clusters of fiberglass conveyed past the discharge section of the conveyor. The detector is connected to a control unit which calculates the approximate amount of fiberglass conveyed past the detector and deposited into the centrifuge. In response to the amount of fiberglass detected, the control unit directs the operation and timing of the recycle system by selectively controlling the speed of the centrifuge and by placing the conveyor system between a discharge mode and an accumulation mode.

Abstract: A dumping hopper and truck trailer washing stand used in connection with cleaning the interior of a truck trailer. The hopper and stand together form a trailer washing apparatus. The stand includes support legs that extend from a ground surface to a platform. Beneath the platform is a container storage area where the hopper can be positioned beneath the platform. To clean the interior of a truck trailer, a truck is positioned adjacent to the stand while the hopper is located below the platform. Waste material is washed from the interior of the trailer and onto the stand's platform. The waste material falls through a grate on the platform and into the hopper located below the stand. A frame structure on the hopper enables the hopper to be transported and vertically positioned by a fork lift. The hopper has a loading position where the hopper is in an upright position with waste material held therein and a dumping position where the hopper is in a tilted-downward position.

Abstract: A stripped bobbin treatment apparatus for inspecting, cleaning and packing bobbins which have been stripped of residual yarn includes a conveyor, an inspection station. a cleaning station and a packing station. The conveyor is in the form of a plurality of endless belts trained around sheaves which permit the bobbins to travel in non-linear paths on the conveyor. Bobbins which are not completely stripped may be redirected to a stripper for additional stripping, and bobbins which are damaged may be discarded. The cleaning station is traversed by the conveyor and includes a housing and nozzles therein for spraying water to clean the bobbins. These include nozzles mounted for pivoting reciprocation in a plane perpendicular to the path, nozzles mounted for pivoting reciprocation in a horizontal plane parallel to the path and nozzles located below the path mounted for rotation about a vertical axis to spray water upwardly through the bobbins.

Abstract: A fluid operated low profile wrench has a rack and gear drive system to provide an accurate lever arm. The gear is a gear segment which forms part of the output lever of the wrench. The wrench is capable of using a multiplicity of drive heads and/or a multiplicity of reaction elements.

Abstract: Apparatus for assuring complete stripping of fibers from a bobbin in a bobbin stripping system includes a bobbin stripping station including oscillating water jets, a viewer to view bobbins as they are being stripped at the stripping station and to generate signals representative of a bobbin being stripped. A water jet position sensor generates a signal indicative of whether the position of the water jets is such that the viewer's view of the bobbin is unobscured. An indexing conveyor moves fully stripped bobbins from the stripping station and unstripped bobbins to the bobbin stripping station. A bobbin transport sensor generates a signal when the indexing conveyor is moving a bobbin to or from the bobbin stripping station. A computation device selects pixels of the signals from the viewer, counts a first number of pixels indicative of fibers and a second number of pixels indicative of bobbin.

Abstract: A torque wrench is presented which has dual output/reaction modes, with the input and output operating in the same direction in both modes. In one mode, a stationary reaction adapter is outside of an inner rotating torque adapter; in the second mode, a stationary reaction adapter is inside of an outer rotation torque adapter. Torque levels are measured by strain gages mounted on a single reaction arm and are read out digitally.

Abstract: An improved textile bobbin cleaning system for removing fiberglass remnants, rovings, yarn, waste or the like from a textile fiber spool, core or bobbin in order that same may reused to store or rewind with new textile fibers, threads, yarn or the like. The invention utilizes an endless indexing conveyor system which aligns bobbins which need to be stripped of remnant fibers before a geared oscillating water jet cutting system which hydraulically cleans the bobbins by cutting the fiber remnants. A pneumatic clamping system has the flexibility and utility to secure bobbins of different design and dimension for the hydraulic stripping action. In addition, a sealed waste conveyor carries away the fibrous waste designed to eliminate waste accumulation on the conveyor mechanism and removes the cuttings for disposal. Also a bobbin removal conveyor is provided for which removes processed and cleared bobbins from the cleaning area to be packaged for transporting for further bobbin usage.

Abstract: A torquing tool is provided which is adapted to tighten threaded connections located in hard to reach places to precise torque values. The torquing tool comprises a housing having a pair of spaced arms pivotably attached thereto. Each arm include a series of idler gears which terminate at a reversible output gear or drive shaft. The housing includes a gearing mechanism which drives a selector gear. The selector gear pivots between a first position which will actuate the idler gears and output gear in the first arm and a second position which will actuate the idler gears and output gear in a second arm. During use, the output gears of the torquing tool are mounted on a pair of spaced nuts; with the arms being pivoted to adjust for differing bolt centers. Next, a handle extending from the housing is actuated to move the selector gear between the first or second position to acutate the gears in either the first or second arms.

Abstract: A spline centering device is arranged on a member having a spline in mating engagement with a spline on a member having a hole not otherwise having spline centering or piloting characteristics. The centering device features a spring loaded tapered member which locks into the hole to provide the required piloting affect and to therby reduce spline motion and spline tooth wear.

Abstract: A mechanically rigid joint is formed between two different metals by completing the joint in a forging operation. A part (14) made of one metal is placed in a die form (20) and is maintained at a temperature below that required for forging. A billet (23) made of the material from which the second part (13) is to be formed is coated with boron nitride at an interface (16). The boron nitride is thermally treated while on the billet (23) by heating the coated billet (23) in a non-oxidizing atmosphere. The billet (23) may then be heated and placed in the die (20) so that the billet (23) can be formed into the second part (13), engaging the first part (14) at an interface (16) defining the joint. The joint (16) is stabilized by providing suitable coatings for the materials, particularly at the interface (16).

Abstract: A shaft assembly (11) having a spline (16) with an anti-backlash device operable due to centrifugal force to engage both sides of internal spline teeth during rotation. The spline (16) includes a main force transmitting portion (18) and a moveable spline sleeve (22) which during operation engages the side of teeth opposite the side engaged by the main force transmitting spline. Spline sleeve (22) rides on helix member to move slightly circumferentially as it is moved axially by a centrifugal force actuated member. A bar which is pinned to the spline (16) has one end which moves radially outward due to centrifugal force as the spline (16) is rotated and another end which engages and moves the spline sleeve (22) axially. When the spline sleeve (22) is moved, the splined end on the shaft assembly (11) is locked or wedged into engagement with the mating internal spline (14).

A part (14) made of one metal is placed in a die form (20) and is maintained at a temperature below that required for forging. A billet (23) made of the material from which the second part (13) is to be formed is placed in the die (20) so that the billet (23) can be formed into the second part (13), engaging the first part (14) at an interface (16) defining the joint. The joined parts (13, 14) are then machined into their final shape. The joint (16) is stabilized by maintaining appropriate temperatures of the materials to compensate for expansion and contraction after forging, and by providing suitable coatings for the materials, particularly at the interface (16).

Abstract: The invention is an integrated hydraulic control circuit for actuating the thrust reversers and variable exhaust nozzle on high preformance gas turbine engine powered aircraft. The hydraulic circuits for both systems are integrated into a single housing and are served by common elements. The circuit for the deployment and stowage of the thrust reverser buckets is hydraulically sequenced inhibiting the application of hydraulic power to the actuators prior to withdrawal of the locking pin. In a like manner, the thrust reversers must be fully retracted before the locking pin is deployed. The hydraulic circuit for the thrust reversers also includes a pressure compensating circuit which reduces the pressure applied to thrust reverser actuators with the thrust reversers in the stowed position.
