Abstract: A welding system includes an imaging system that takes frame by frame pictures of a weld puddle. The imaging system is located in the weld torch. From the images puddle length and width are determined. The length and width are applied against stored membership functions that cover a range of different weld current characteristics and the degree of membership of each dimension in those functions is determined, producing an alpha factor for each membership function. This provides a fuzzy current requirement. Stored values for moment and area for each membership function are multiplied by the alpha for the respective function. The total of the moments is divided by the total of the areas to produce a desired weld current. The weld head includes a weld wire feeder that is driven by a servo by which the wire can be fed along either side of the weld joint. The wire feeder is gear driven in such a way that it does not interfere with the optics in the weld torch. The optics include a strobe to illuminate the puddle. Signal processing includes a process for interpolating the puddle centerline from the range in puddle widths over successive strobed images of the puddle. The head is positioned automatically over the centerline.

Abstract: A loading assembly (30, 200) applies a lateral force to an axis (23) of a vehicle spindle (12) and includes a support frame (54; 216A, 216B) and a wheel adapter housing (16, 206). A loading member (36, 208) is pivotally joined to the support frame (54; 216A, 216B) at a position spaced apart from the wheel adapter housing (16, 206). A plurality of spaced apart struts (32A, 32B, 32C; 202A, 202B, 202C) connects the loading member (36, 208) to the wheel adapter housing (16, 206). An actuator (62, 204) applies a selected force to the loading member (36, 208) to apply a lateral force to the vehicle spindle (12). In a first embodiment, an adjustable coupling (65, 284) connects the actuator (62, 204) to the loading member (36, 208) to emulate a rolling radius of a tire assembly mounted to the vehicle spindle (12). In a second embodiment, a second loading member (44, 214) is operably connected to the first-memtioned loading member (36, 208). A second actuator (80, 218) applies a force to the second loading member (44, 214) to apply a selected moment to the vehicle spindle (16).

Abstract: A feedback control system (50, 100) provides an adjusted command signal (60) to a plant (16) in response to a command signal (13) having command signal components. The plant (16) provides a feedback signal (30) representing an achieved response to the adjusted command signal (60). An adaptive filter (34) adjusts the amplitude of relatively high frequency command signal components in accordance with a dynamic behavior. A compensator (63) adjusts the dynamic behavior in response to the feedback signal (30) and the adjusted command signal (60). A summing element (58) generates the adjusted command signal in response to the output from the adaptive filter (34) and command signal components passed by a passing device (54).

Abstract: A sonic delay line assembly (10) suitable for shipping in coiled form and allowing for expedited installation, particularly in liquid storage tanks. The sonic delay line assembly (10) comprises a sonic waveguide (36) made of solid wire, which also serves as an electrical pulse conductor for the generation of sonic pulses on waveguide through interaction with a positionable static magnetic field source (32). A sonic waveguide containment (17) can be provided to protect the flexible tubing (14) and sonic waveguide. Positioned around the containment (17) and free to ride up and down the containment (17) as liquid levels (28) in the tank vary is a float (20). The float carries an annular magnet with poles axially aligned with sonic waveguide to provide the magnetic field with which the magnetic fields of the electrical pulses on the sonic waveguide interact.

Abstract: An extensometer (10) is used for measuring axial and diametral strains in a material test specimen (12). The extensometer (10) comprises an assembly of extensometer sections (11, 13) positioned on diametrally opposite sides of the specimen (12) with specimen engaging points (22, 35, 67, 83) spaced axiallly along the specimen. The extensometer assembly (10) is arranged so that the two extensometer sections (11, 13) will average the axial strain measured by the two extensometer sections (11, 13). Also, if desired, the two extensometer sections (11, 13) may provide an indication of the average change in diameter of the specimen at the location of the upper contact points (67, 22) and at the location of the lower contact points (35, 83) of the extensometer sections (11, 13) on opposite sides of the specimen (12). The support system (15) between the extensometer sections (11, 13) provides for the necessary degrees of freedom to provide measuring only in the axis desired, and sufficient restraint in other axes to insure that accurate measurements are obtained.

Abstract: A strain gage element system includes a spring flexure member (26) on which strain gages (37) of convention design are mounted, and a heat shrinkable waterproof tube (50) that is placed over the gage (37) and the support and shrunk into place. The spring flexure member (26) is formed so that it has a substantially constant peripheral length about the perimeter of any cross-sectional plane perpendicular to the longitudinal axis of the spring flexure member (26). The heat shrinkable tube (50) must be selected in size and shrinkage characteristics to tightly envelope and shrink against the gage (37) and spring flexure member (26) and seal the gage (37) completely to prevent moisture of any kind from getting into contact with the gage (37).

Abstract: A modular magnetostrictive displacement sensor is disclosed having a waveguide of magnetostrictive material extending from a first housing and protected by a member of fiber reinforced composite material. There is circuitry in the first housing for generating electrical pulses along the waveguide and a converter for generating an electrical signal in response to a torsion pulse in the waveguide caused by a magnet disposed proximate the waveguide when the electrical pulse passes the magnet position. In one embodiment the waveguide and its protective member is received within a second housing. One or more magnets may be mounted within the second housing or externally on or near the second housing for movement to the waveguide. Alternatively the sensor may be used without the second housing.

Abstract: A tensile test (13) grip for holding a specimen (14) has a pullrod (25) that is mounted in an annular bore (37), and carries a piston head (26) that fits within a piston chamber (31), and both the pullrod (25) and piston head (26) are sealed on their outer surfaces with respect to the housing (32) forming the piston chamber (31), to form an enclosed chamber (11) in which hydraulic fluid can be provided to permit swiveling alignement of the pullrod (25) and the piston head (21) relative to the housing (32) that is a function of the direction of loading between the pullrod (25) and the housing (32). The seal on the pullrod and the seal on the piston head with respect to the respective surfaces on which they seal is on a very short part spherical land (43) to permit the pullrod (25) and piston head (26) to shift with respect to the housing (32) and provide self alignment. The pullrod (25) and piston (26) can swivel freely for a limited amount to provide alignment during tensile loads.
