Abstract: A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the sidewalls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the sidewall and overlapping the top chord.

Abstract: A graft caliper provides for a first member having a first pick at its distal end and its proximal end attached to a handle. A second member of the graft caliper is disposed above the first member and has a second pick at its distal end that extends beyond the first pick. The proximal end of the second member is attached to an adjuster which causes the second member to move from a first position to a second position in order to change a distance the second pick extends beyond the first pick. The graft caliper provides for an indication of at least one metric for describing the distance the second pick extends beyond the first pick and places an identifier on a surface of bone representing the location of a tunnel to be formed through a femur, tibia or any other anatomical structure.

Abstract: A rail road freight car truck, which may be a Barber S2HD truck or other kind of truck, has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The sideframes are mounted on a pair of wheelsets. The bolster may be resiliently sprung and may have friction dampers. Either the friction dampers or the sideframe column wear plates may have a non-metallic wear plate, or wear surface, which may be replaceable, and which may tend to exhibit non-stick slip, or reduced stick slip behaviour in use. Bearing adapters may be mounted on the bearings of the wheelsets, and resilient pad members may be mounted on the bearing adapters. The pedestal seats may sit over the resilient pads. There may be a discontinuity in the vertical load path between the pedestal roof and the bearing.

Abstract: A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by closure members, at least one of which is movable. The closure members come together to a closed condition or position for retaining lading. When apart, in an open position or condition, lading may be discharged. A seal member or seal member assembly is mounted to one or both of the closure members. When open, the seal member or seal member assembly lies substantially flush with, or shy of, the slope of the surface of the closure member. When closed, the seal member may be self-energizing, in the sense that as lading is added the seal may tend to seal more tightly. The seal assembly may include a cantilevered spring that presents a land to the opposed closure member, and a fulcrum, over, or across, which the spring is cantilevered, such that pushing down on one end of the spring may tend to cause the other end to flex upward.

Abstract: A method for acoustic imaging of a tubular shape, the tubular shape having an outer surface and an inner surface. The method includes directing an ultrasonic beam through a focusing lens. The focusing lens has a planar edge and a concave edge located on opposite sides of the focusing lens. The ultrasonic beam enters the focusing lens through the planar edge and exits from the concave edge such that the ultrasonic beam enters the outer surface of the tubular shape, passes to the inner surface and the beam is reflected at the inner surface, passes through the outer surface and through the focusing lens in the opposite direction. The ultrasonic beam that has passed through the focusing lens in the opposite direction is then converted into a video output that displays an image of the inner surface, the outer surface and an internal volume image of the tubular shape.

Abstract: A method for acoustic imaging by angle beam, which includes generating a sound wave, coupling the wave at an angle to a first surface of a test piece via a physically continuous path. The test piece also has a second surface. The angle being such that the wave progresses along a vectors at an angle to the first surface and the second surface and along the test piece via a plurality of sound reflections reflecting between the first surface and the second surface at points progressing away from the transducer location. The angle also being such that the sound reflections at the first surface produce energy at the first surface such that a first part of every reflection of the wave continues through the first surface in the form of wave through a media toward a CCD acoustic imaging camera, while a second part of the reflection continues along in the test piece.

Abstract: A movable barrier operator system includes a barrier-motor electrical driver, a first input device for receiving operating commands, a second input device for developing system status and a controller for storing a record of all input commands received and a record of all events occurring to the movable barrier and for enabling operation of the electrical driver in response to an input command. The first input device may be a DTMF receiver or a telephone entry system. Events stored include barrier obstructions and barrier operator failures. The controller, responsive to a stored event, enable the telephone entry system to contact a service provider. For facilities with multiple barriers and a DTMF receiver at each operator, a special circuit normalizes the amplitude of a transient analog tone burst (such as from a DTMF transmission) without any transient level overshoot.

Abstract: A bone anchor includes first and second anchoring legs and a bridge joining the anchoring legs between their proximal and distal ends. Portions of the anchoring legs on a proximal side of the bridge are configured to elastically compress together in response to an insertion force applied to the bone anchor during insertion of the bone anchor into a bone hole, and to plastically splay apart in response to a withdrawal force applied to the bone anchor. Portions of the anchoring legs on a distal side of the bridge are configured to compress together in during application of the withdrawal force to limit the splaying of the proximal portions of the anchoring legs. A method for attaching soft tissue to bone includes inserting the bone anchor with attached suture into the bone, and deploying the bone anchor within the bone by applying tension to the suture.

Abstract: A laser centering apparatus including a frame for supporting a laser, the frame being adapted for selective attachment to a pipe, and a laser rotatably connected to the frame. The laser can be rotated in a plane containing the centerline of an existing pipe to enable quick and easy alignment of pipes parallel to an existing pipe.

Abstract: A number of arrangements and methods that achieve concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than half the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components.

Abstract: A device and method for measuring the intensity of high amplitude strain waves caused by the impact of a projectile or the detonation of an explosive on armor plate are disclosed. The sensor may be configured as a shock wave sensor. The shock wave sensor may include a solid, cylindrical bar having a pair of strain gages located at opposite positions on an exterior surface of the bar. The strain gages may be located along one end of the bar proximal to a test specimen such as armor plate.
