A cutting tool, and a loose top therefore, includes two parts detachably connected to each other via a threaded joint in which co-operating male and female threads are included in the form of helicoidal ridges. The profile shape of each helicoidal ridge is defined by a top and two flanks, which delimit a helicoidal groove having a bottom. The first flank is inclined in relation to a center axis of the tool at a first angle that is smaller than a second angle of the second flank in relation to the center axis. Accordingly, the thread ridge is reinforced in comparison with thread ridges having a symmetrical profile shape, whereby larger tensile forces than compressive forces can be applied to the threaded joint while avoiding damage to the thread ridges.

Systems for generating electric power from wind are disclosed, which use buoyant aircraft and spinnaker sails to generate very large pulling forces, which will be used to drive electric generators. The buoyant aircraft, referred to as “airbarges”, will have large, wide, and flat shapes which combine various traits of kites, manta rays, and “flying wing” aircraft. They can be flown “nose up” during the pulling stage of each power cycle, and “nose down” during retrieval. Spinnaker sails are comparable to horizontal parachutes, with tethering systems that will enable them to be pulled back to a starting location in a “luffing flag” or “closed umbrella” configuration. Because of various factors, spinnaker sails can generate much greater power output and operating efficiency than 3-blade wind turbines. “Webbing sails” made from interwoven straps also are disclosed, which can be used even in extremely high winds.

An actuator mechanism having a different magnet polarity arrangement than the conventional mechanisms is provided. The actuator mechanism 100 has a magnet unit 210 that includes magnets 30 and an electromagnetic coil unit 110 that includes an electromagnetic coil. the relative positions of the magnet unit 210 and the magnetic coil unit 110 can change. The magnet unit 210 includes a yoke member 20 and two or more magnets 30. The two magnets 30 are pulled toward the yoke member 20 in the state where identical poles face each other across the yoke member 20.

A low cost pretensioner is provided by using an ignitable charge and initiator integrated with a piston which is disposed in a cylindrical metal tube that has a common straight gas generation and piston travel bore so that a inexpensive metal tube rather than a complex casting can be used. A cable is connected at one end to the piston and passes through a cable deflection device having a locking device for locking the cable against travel in a reverse direction after tightening the seat belt system. The locking device may be an inexpensive, one-piece wedge-shaped clamping or gripping device which transfers the high tensile forces from the passenger's body pulling on the cable through the deflection device to a vehicle anchorage rather than through a locking device which is disposed within the cylinder tube which must have tube walls sufficiently strong to withstand such high tensile forces.

A flexible abrasion resistant omnidirectionally reflective, preferably retractable, flat belt pet leash / pet collar exhibits omnidirectional reflectivity. The omnidirectionally reflective flat belt pet leash reflects an incoming light beam back in the direction from which it emanated. The reflected light beam provides accurate illumination of the pet leash and the location of the pet during dusk or nighttime hours. This reflective pet collar and / or leash is created by forming a substantially flat reflective woven band composed of narrow width reflective strips that comprise woven or knitted reflective threads. A raised, braided, dimensional band is optionally placed atop the substantially flat reflective woven band to further increase reflectivity and visibility thereof. The flexible reflective threads are composed of microsphere retroreflectors coated with water resistant compound and, optionally, a poly-phosphorus material. The collar or leash may alternatively be formed by embedding a plurality of microscopic reflectors into the braided weave of a fabric. Upon being embedded, the microscopic reflectors act like smooth mirrors which operate collectively to provide a reflective medium. Due to the braided weave of the fabric and the presence of the raised, braided dimensional band atop the woven fabric, microscopic reflectors within the dimensional band direct light incident thereon from virtually any angle back to its source.

A brake hose includes two reinforcing layers in a rubber base. The brake hose comprises an inner tube rubber layer having a flow path for flowing fluid, a lower yarn layer formed by braiding first yarns around the inner tube rubber layer and an upper yarn layer formed by braiding second yarns around the lower yarn layer and a cover rubber layer covering the upper yarn layer. A lower yarn layer duty LD given by the equation, LD(%)=(LRP / PRP)x100, has a value of 50-65%,where LRP denotes an inner pressure at which a brake hose without the upper yarn layer and the cover would burst, and PRP denotes an inner pressure at which the brake hose would burst.
