Abstract: An apparatus for performing ultrasonic evaluation of a portion of a pipe includes a frame assembly and a plurality of ultrasonic sensors disposed in the frame assembly. The frame assembly includes a frame which is structured to cooperatively engage an outer surface of the pipe. The frame has a curved surface which is curved about an axis which, when the frame is engaged with the pipe, generally coincides with the central longitudinal axis of the pipe. The curved surface is generally defined by a radius which is generally equal to an outer radius of the pipe. The plurality of ultrasonic sensors are disposed in the frame assembly a fixed distance from the curved surface.

Abstract: A visual inspection system [100] includes a remote end [110] that is moved through a conduit [1] with a flexible pushrod [400]. The remote end [110] having at least one carriage assembly [130] with encoders [140] indicating a distance traveled within the conduit [1]. The visual inspection device [100] has a longitudinal camera [150] to identify view down the length of the conduit [1], but also has at least one transverse camera [160] adapted to visually inspect an inside surface [3] of the conduit [1]. Also, the transverse camera [160] may be used to inspect other conduits that connect to conduit [1].

Abstract: The thumb pad, in a preferred embodiment, is disposed in the thumb hole of a bowling ball. The pad is a thin, multi-layer, highly flexible pad. A first elongated tape-like layer has an adhesive surface adapted to be adhered to the bowling ball wall defining the thumb hole. The length of the thumb pad does not exceed the depth of the thumb hole. The width of the thumb pad is approximately the width of the backside of the thumb. The backside of the thumb is the side opposite the palm side of the thumb. The thumb pad includes a second elongated tape-like layer overlaying the first tape-like layer opposite the adhesive surface. The second layer has a low friction surface (preferably TEFLON coated) adapted to be positioned adjacent the backside of the thumb. The thumb pad further includes a thin, compressible, foam-like pad interposed between the first and second layers at a position remote from one end of the overlaid first and second layers.
