Abstract: The present invention provides a wear liner assembly (13) adapted to be secured to a structure (15). The wear liner assembly comprises a wear liner (14) having a first material secured to a backing plate (17). The backing plate has at least one hole (43) therethrough. A first fastener portion is adapted to co-operate with a second fastener portion to securing the wear liner to the structure. The first fastener portion is received in the at least one hole and is at least partially housed within the wear liner.

Abstract: A lock nut assembly 10, 10? has a first component 12 provided with a threaded axial through hole 19; and a second component 14 provided with an axial hole 31. The first and second components 12, 14 are detachably coupled together and arranged so that both components are simultaneously engagable with a common tool to effect application of the assembly 10, 10? onto a threaded member 22 by operation of the tool to impart torque to the assembly 10, 10? in a first direction. The first component 12 initially engages the threaded member 22 with the second component 14 following. The first component 12 provides fastening to the threaded member 22 and is torqued as required. The second component 14 acts to lock the first component 12 onto the threaded member 22.

Abstract: A nutless bolt includes a body having a shaft and a stop coupled to the shaft. Shaft is dimensioned to allow passage through a hole formed in a structure into which the bolt is inserted. The stop prevents body from falling into or through the hole. An axial bore formed in body houses a locking mechanism extending radially from shaft to lock body and nutless bolt in the hole. An actuator pin movable along the bore in a generally down hole direction through various positions. Position L1 is a pre-application position; position L2 is a locking position; and position L3 is a release position. Pin is movable in the down hole direction from L2 where the pin causes the locking mechanism to extend radially from shaft to lock the body in the hole, to L3 where the pin is retained in the body and displaced relative to the locking mechanism.

Abstract: A wear plate system comprises whole hexagonal plates configured to tessellate with each other, part plates which are derived from respective whole plates, and second triangular plates. The plates are provided with holes to receive fasteners for securing the plates to a structure. The holes are located in the plates in a configuration such that when the plates are tessellated to form a substantially continuous lining, the holes form a repeating pattern. The second plates are configured to facilitate the formation of straight edges on the lining to match an edge of a structure to which the lining is attached.

Abstract: A wear sensor comprises an electric circuit supported on a substrate. The circuit comprises a plurality of discrete elements which are coupled in parallel with each other across conductive rails. The circuit is electrically connected with a measuring device. The measuring device measures an electrical characteristic of the circuit such as resistance. The sensor is disposed in or adjacent an object which is subject to wear and wears with the object. As the sensor wears, the elements are sequentially decoupled from the circuit thereby changing the characteristic measured by the device. This change provides an indication of the amount of wear of the object.

Abstract: A wear measuring device comprises a body having a wearable portion at the first end, a light conductive region internal to the body and the light conductive region has a reflective portion within the wearable portion. The reflective portion is configured to reflect light directed through the light conductive portion and at the reflective portion back down the light conductive portion. One or more characteristics of light reflected by the reflective portion are related to the extent of wear to the wearable portion. An optical component comprises a longitudinal axis and a plurality of reflective elements spaced along said longitudinal axis. The reflective elements are arranged to reflect light directed in a direction substantially aligned with said longitudinal axis. The magnitude of the reflectance is a function of physical degradation, ablation or wear of the component in a direction along the length of the component.

Abstract: A fastener system for fixing hardened plates includes a fastener element having a frusto-conical head and a threaded shaft portion, wherein a smallest outer diameter of the frusto-conical head is adjacent the threaded shaft, and a largest outer width of the shaft is smaller than a smallest diameter of the head.

Abstract: A building structure (10 or 10?) has a wall (16) including a plurality of wall elements (12 or 12?). Each wall element is connected to a plurality of other wall elements so as to form the wall. Each wall element includes a connecting means for connecting the adjacent wall elements together to form the wall. The wall is formed at least three consecutively connected rings (15 or 15 and 17) of interlocking wall elements. Each of the wall elements in each ring being of the same size. Each of the wall elements in a first ring of the consecutively connecting rings being larger than the wall elements of a second ring of the consecutively connected rings and each of the elements in the second ring being larger than the wall elements of a third ring of the consecutively connected rings.

Abstract: A building structure having a plurality of wall elements connecting together to form a wall is disclosed. The wall elements have a plurality of sides, each side is connected to an adjacent side of a wall element by an interlocking connection means. Methods of building a structure with the wall elements are also disclosed.

Abstract: A dust retention system for locating above a product vessel includes a support member mounted above the product vessel, a door including an engaging portion detachably connected to the support member and an adjustment device for adjusting the angle of the door with respect to the support member. The door includes a striking portion adjacent the engaging portion with at least a section of the striking portion being constructed of a resiliently flexible material. Product falling onto the striking portion causes the resiliently flexible material of the striking portion to be deflected by the weight of the product, thereby forcing the door from a closed position, where dust is prohibited from escaping the product vessel, into an open position where the product passes across the door into the product vessel. Thereafter the door, without the weight of said product, returning to the closed position under a bias force exerted by said resiliently flexible material.
