Abstract: In a mechanically redundant actuator system, the actuator has a structurally redundant members for attaching it between a stationary anchor point to a movable control surface. Specifically the actuator consists of a cylinder body, a double action piston with a piston rod attached to the control surface at one end and a swivel bar at the other end. Single or multiple tie rods are attached between the swivel bar and the movable control surface. Each tie rod can withstand one half the load of the piston rod. Also, trunnion links attach the cylinder body to the structure. Each trunnion links can withstand the full limit load with or without any load factors. The trunnion fittings can be any configuration that provides a structural reaction, and provides a dual load path and freedom of movement in at least two axes. At least two of these actuator units are required per surface. Also, a dual tandem control valve with a hydraulic compensator for each actuator is required.

Abstract: The invention relates to a cooling assembly for a fiber spinning machine, which forms a cooling zone for the fibers and has openings, through which a cooling fluid flows to the fibers. The cooling assembly is formed by a plurality of overlying annular elements. Arranged between the elements are spacers so as to permit air to flow between the elements into the cooling assembly.

Abstract: Permanent magnets affixed to one structure produce a repelling force to magnets affixed to a larger structure that encloses the one structure to suspend and hold the one structure entirely within the larger structure, without physical contact therebetween.

Abstract: The spade-type boring bit includes an elongate shank defining a central longitudinal axis and a blade portion joined to one end of the shank. The blade portion includes a pair of generally flat side segments extending laterally from the central longitudinal axis and having a respective forward cutting edge and a respective chamfered corner portion. Each chamfered corner portion includes a chamfered edge which extends both axially rearward and laterally outward from the respective forward cutting edge so as repeatedly cut the peripheral wall of the resulting hole as the spade bit is rotatably advanced through a workpiece. The spade bit therefore produces a high-quality hole having a smooth peripheral wall and relatively clean entry and exit points. In addition, the forward cutting edges of the spade bit can be aligned with each other along a centerline which passes through the central longitudinal axis of the elongate shaft so as to increase the efficiency with which the spade bit drills.

Abstract: A hairdressing comb (10) comprises a series of spaced pairs of hair-lifting teeth (16.1, 16.2), the teeth of each pair defining between them a gap 18 into which hair can enter. Each hair-lifting tooth has a hair-lifting formation (20.1, 20.2), the hair-lifting formations of each pair of teeth both extending into the corresponding gap (18). The hair-lifting formations (20.1, 20.2) of each pair of teeth (16.1, 16.2) are staggered with respect to one another in the longitudinal direction of the teeth (16.1, 16.2), and the one hair-lifting formation (20.2) extends into the gap (18) to a point laterally beyond that to which the other hair lifting formation (20.2) extends into the gap (18).

Abstract: A garment for use in electrically-scored contact sports competitions is described. The garment is designed to cover at least the upper torso of a wearer, and is fabricated from electrically conductive yarns which cooperate with an electric sports implement to register a score when the implement contacts the electrically conductive garment. At least a portion of the upper torso portion is made from a stretchable, electrically conductive material. The garment is particularly adapted for use in fencing competitions, and can be made substantially entirely from the stretchable electrically conductive material or from a combination of stretchable and non-stretchable conductive materials.

Abstract: A method and apparatus for controlling the throat area, expansion ratio and thrust vector of an aircraft turbine engine exhaust nozzle, includes means, such as deflectors and/or injected air, for producing and controlling regions of locally separated flow. The exhaust nozzle also allows control of the thrust vector angle defined by the gas exiting the nozzle to provide increased directional control of the aircraft.

Abstract: A golf club, comprising a head having a striking face, a front toe, a rear heel, and opposing top and bottom edges. The club also includes a shaft joined to the heel of the head, and so as to define a juncture portion therebetween. Also at least one opening is formed through the juncture portion so as to define a pair of spaced branches on opposing sides of the opening.

Abstract: An improved die for a superplastic formation process and the process that uses an interface for pressurized gas that is part of the forming die so that tube welding to the forming pack can be eliminated. In one embodiment, the interface is fixed to the die and in a second, for use to pressurize the interior volume of finished parts with inert gas when the finished parts are to be removed from the die hot (1400.degree. F.), the interface becomes welded to the pack during the forming process so that the interior of the part can be flooded with inert gas during the cool down process.

Abstract: An apparatus for winding continuously produced cable about a take-up spool includes a frame, a traveler assembly, multiple take-up spool assemblies, and a translation system for automatically moving the traveler assembly into an aligned position with each spool assembly. The traveler assembly is movably mounted to the frame for receiving and for paying out continuously produced cable. Each spool assembly comprises a pair of opposing arms and a cable snagger. Each pair of opposing arms is configured to rotatably mount a spool therebetween. The cable snagger is secured to a member rotatably mounted on one arm and is configured to extend through an aperture in a flange of a spool in order to engage a free end of a continuously produced cable. A release mechanism for disengaging the snagger from the cable, once at least one wrap of the cable has been wound about the spool, is also provided.
