Abstract: A shroud for a track shoe grouser protector includes an elongate shroud body having weld holes formed in a first shroud leg and a second shroud leg attached to a base in the elongate shroud body. The shroud may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs flared outward to form a grouser opening for positioning the shroud upon a track shoe grouser in a ground-engaging track system. An inventory of shrouds includes long shrouds and short shrouds positionable in a plurality of different assembly combinations to shield grousers in track shoes having a range of sizes.

Abstract: Articles comprising a surface or porous substrate and having on said surface or porous substrate a coating comprising microfibrillated cellulose or nanocellulose, methods of applying a coating comprising microfibrillated cellulose or nanocellulose to a surface or porous substrate, compositions comprising microfibrillated cellulose or nanocellulose, and the use of such compositions in methods of preparing an antimicrobial surface coating, and improving filtration efficiency and preparing an antimicrobial surface and/or antiviral surface coating.

Abstract: A ground-engaging track includes a track chain formed of standard links and at least one master link. The master link include a first half link and a second half link, clamped together by way of a forward bolt and a rearward bolt. Clamping surfaces of the first half link and the second half link form a first tooth set and a second tooth set, respectively, which may include a total of 2 or 3 full teeth and tooth roots, confined in distribution between a forward bolt hole and a rearward bolt hole.

Abstract: An idler assembly includes a cylindrical hub defining an axis of rotation, a radial direction, and a circumferential direction. A stepped circumferential surface of the cylindrical hub has a first radially inner face, and a radially outer cylindrical face. Mounting holes extend radially into the radially outer cylindrical face. A first idler segment is attached to the cylindrical hub, and includes an at least partially flat body having a first planar chain link contacting surface. The cylindrical hub has a first set of metallurgical properties that is different than the second set of metallurgical properties of the first idler segment.

Abstract: An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

Abstract: A master link for a chain assembly is provided. The master link includes a body member with a first side, a second side positioned opposite the first side, a shoe surface configured to receive a track shoe, and a rail surface positioned opposite the shoe surface. The master link also includes first and second apertures extending through the body member from the first side to the second side and third and fourth apertures located between the first and second apertures. The master link also includes a strut member dividing the third and fourth apertures. The master link also includes a first gap located in the body member and extending from the first aperture to the third aperture and a second gap located in the body member and extending from the fourth aperture to the second aperture. The master link further includes a third gap located in the strut member and extending from the third aperture to the fourth aperture.

Abstract: Embodiments of the present disclosure provide method and devices for repairing computer files that impair network communications. In this regard, one embodiment of such a method, among others, can be broadly summarized by the following steps: extracting information corresponding to settings for network communications from a local resource file, wherein the local resource file is embedded within an application executed by a computer for repairing the files impairing network communication on the computer; and replacing information within a registry of the computer with at least a portion of the extracted information, wherein the replaced information includes settings pertaining to facilitation of network communications on the computer. Other methods and devices are also provided.

Abstract: Apparatus and method for the inspection of an object. A linear array of cameras are located in a stationery position with the object moved over them. An image processor first applies calibration and perspective alterations to the consecutive frames of the cameras, then mosaics the frames together to form a single mosaiced image of the object. An undervehicle car inspection system is described which provides a single image of the entire underside of the vehicle, to scale.

Abstract: Apparatus and method for presenting a highly spatially accurate visualisation of a scene from which measurements can be taken. A sensor is located in relation to a camera, and provides positional characteristics of the camera as it collects frames of video images. Using the positional characteristics the frames are corrected. The corrected frames are then synchronised to form an accurate mosaic of a scene. Example embodiments are described where the moving camera is used to survey or inspect underwater apparatus, roads, runways, railways, crime or accident scenes, archaeological digs and the inside of boilers, chimneys and pipelines.
