  • Publication number: 20200271405
    Abstract: An improved gas piston system for the automatic loading of a rifle, especially a rifle of the M-16/AR-15 type. The system employs a barrel nut, or an adaptor to a barrel nut, that has been modified to secure one end of a gas piston system. The other end of the gas piston system, namely the piston rod, engages, either directly or indirectly, the key on a bolt carrier group. This configuration positions the gas piston system at a point starting near the barrel nut and extending to the bolt carrier group of the rifle, while a gas tube extends from the gas block to the gas piston system a point near the barrel nut.

  • Patent number: 5537876
    Abstract: Apparatus and method for nondestructive evaluation of butt welds. The present invention in its broadest form includes an apparatus and method for detecting flaws in butt welds in steel sheets using horizontal shear ultrasonic waves generated on the surface thereof. Observation of reflected waves having amplitude greater than a chosen value signals the presence of significant flaw. To achieve this objective, the present apparatus detects only reflected horizontal shear waves; other modes are electronically removed using bandpass filters, since they occur at different frequencies. The invention may therefore be used in the presence of surface structures such as clamps and the like, and in the presence of surface nonuniformities in the vicinity of the weld, thereby permitting on-line flaw detection steel mill environment without interfering with the line output.

  • Patent number: 5154081
    Abstract: The system for field measurement of texture, stress and related material properties such as formability parameters using ultrasonic velocity measurements through crystalline plate or sheet. Electromagnetic acoustic transducers are utilized to generate, transmit, and receive ultrasonic bursts through the plate at different angular orientations with respect to the plane of the plate. Two of the transducers are driven in series when generating the ultrasonic bursts. Time measurements between transmission and reception of the bursts are precisely derived and converted into velocities. Information regarding stress, texture, and other related material properties such as formability parameters can be derived from these velocity measurements. The system is adjustable to be used for both ferrous and nonferrous crystalline plate. Alteration of the types of ultrasonic waves utilized, and the methods of generating the waves allows different properties such as texture and stress to be derived.

  • Patent number: 4434663
    Abstract: Disclosed is an electromagnetic acoustic transducer for use with electrically conductive objects. The transducer includes an electromagnet for establishing a static magnetic field directed into the object in a first region and directed out of the object in a second region. A meander coil for inducing eddy currents in the object when an alternating current is applied to the coil includes a first serpentine printed circuit on a first side of a printed circuit board and a second serpentine printed circuit on a second side of the board. The source and the coil are so oriented that the vector product of the field and the eddy currents produces an instantaneous force field in the object which is periodically alternately oriented.

  • Patent number: 4305294
    Abstract: Disclosed is a method for determining the thickness of an object, including the steps of generating a higher order mode ultrasonic wave at a first location on the object, varying the frequency of the generated wave, and measuring, at a second location on the object, the minimum frequency at which the generated wave will propagate in the object. Where the ultrasonic wave generated is a horizontally polarized shear wave, the thickness t may be calculated from the relationshipt=(n V.sub.s)/(2 f.sub.c),where:n is the wave mode number,V.sub.s is the shear wave velocity, andf.sub.c is the minimum propagation frequency.Alternatively, the steps may be repeated for the next consecutive frequency minimum and the thickness t calculated from the formulat=V.sub.s /(2 .DELTA.f.sub.c)where: .DELTA.f.sub.c is the difference between two consecutive frequency minima.

  • Patent number: 4295214
    Abstract: Disclosed is an electromagnetic acoustic transducer, including an electrical conductor adapted to carry an alternating current in a current plane, the current being conveyed by the conductor in uniformly spaced, parallel, and alternate directions at any instant, and a source of magnetic flux positioned to direct a static magnetic field parallel to the alternate directions, the transducer thereby being adapted to generate or detect a horizontally polarized shear wave in a ferromagnetic material. The transducer may be made unidirectional by adding a second electrical conductor adapted to carry a second alternating current 90.degree.

  • Patent number: 4248092
    Abstract: Disclosed is a method for generating an ultrasonic wave in a material, utilizing a transducer adapted to induce a higher than fundamental mode wave in the material and a signal generator adapted to drive the transducer at a frequency above the cutoff frequency below which the higher mode wave will not propagate. For a horizontal shear wave, optimal transducer efficiency is obtained by selecting a driven frequency between a minimum cutoff frequency f.sub.c =v.sub.s n/2t and an upper frequency sufficiently close to f.sub.c to drive the transducer with at least a preselected increase in efficiency.
