摘要： A joint restraint for deforming an outer diameter of a pipe for insertion into a socket. The joint restraint can selectively mount to a portion of an irregularly shaped pipe having a maximum outer diameter that differs from a desired substantially constant outer diameter. The joint restraint can have a circumferential ring body surrounding a central axis. A plurality of jacking assemblies can be secured to a portion of the ring body. Each jacking assembly can have a frame and a jacking bolt. The frame can have a threaded aperture that can receive the jacking bolt. Each jacking bolt can be selectively actuatable for radial movement relative to the central axis to deform the pipe proximate the maximum outer diameter of the pipe by selectively urging an outer surface of the pipe to the desired substantially constant outer diameter.

摘要： An apparatus and method for re-rounding a distorted end (e.g., oval-shaped) of a pipe for insertion into a mechanical joint fitting or pipe bell have a circular diameter. The apparatus involves two separate semi-circular members having jack bolt assemblies evenly distributed in each. The two ends of each of the semi-circular members have extensions that can be releasably coupled to join to the two members to form a circular re-rounding tool. A first semi-circular member is positioned on the maximum diameter side of the distorted pipe and the other semi-circular member is placed on the opposite side of the distorted pipe and extensions joined. With an equal number of jack bolt assemblies in each member, corresponding jack bolt assemblies in the two members are diametrically aligned forming pairs. To re-round the distorted end, pairs of these jack bolt assemblies are tightened in a “star sequence” to re-round the distorted end. The re-rounded end is inserted into the mechanical joint fitting or pipe bell and the extensions are decoupled to easily remove the circular tool from the re-rounded end.

摘要： An optical fluid measurement element includes: an emitter that generates an optical output; an absorber that measures an optical input; and a fluid flow pathway, where the optical output of the emitter passes through the fluid flow pathway and is received as the optical input to the absorber after passing through the portion of the fluid flow pathway. An automated method of measuring fluid volume using an optical fluid measurement element includes: activating an emitter; capturing data from an optical sensor; detecting a leading edge of fluid travelling along a flow pathway; starting a counter when the leading edge is detected; and calculating a volume based on a value of the counter. An automated method of measuring fluid attributes along a flow pathway. The method includes: activating an optical emitter; receiving a signal from an optical sensor; and processing the received signal to determine at least one fluid attribute.

摘要： A joint restraint assembly for connecting pipe ends together, or to other objects, which includes a body encircling the pipe. The body has a plurality of cavities adjacent to the pipe with a segment configured to fit into each cavity. One or more threaded bores are disposed through the body into each cavity. A threaded bolt extends through each threaded bore to engage the segment in that cavity, and to pre-load the segment against the pipe when assembled thereon. Mechanical or pressure loading, tending to pull the pipe out of the restraint assembly, causes the segment to self actuate, and the application of increasing load causes a proportional increase to the force engaging the segment to the pipe. The joint restraint assembly reliably accommodates comparatively high levels of mechanical loading and/or pipe internal pressure, and does so without relying upon the limited force produced by the threaded bolt pre-load on the segments at the time of assembly.

摘要： A zoom lens in which two pairs of optical elements of the lens are each movable simultaneously relative to each other to attain desired magnification while maintaining the image surface of the lens system substantially fixed.A common body supporting both sets of lens elements can be moved if required to maintain the focal plane of the lens system fixed. The need for moving the body may arise where the movement of the lens elements causes a shift or displacement of the focal plane of the zoom lens.
