Abstract: A track joint assembly may include a first track shoe including at least one forward pin lug, a second track shoe including at least one back pin lug, a pin extending through a pin bore coupling the first track shoe to the second track shoe, a retainer plate positioned within the pin bore and including an interior surface adjacent the pin, an exterior surface opposite the interior surface, and a recess extending at least partially along an outer circumferential edge of the exterior surface, a stop ring positioned within a stop groove formed in an inner circumferential surface of the pin bore, the stop ring positioned adjacent the exterior surface of the retainer and extending radially inward from the inner circumferential surface such that the stop ring blocks the retainer plate from withdrawing from the pin bore.

Abstract: A method of producing a modified wood product is disclosed. The method comprises heating a resin impregnated wood product in a reactor, the resin impregnated wood product comprising source wood impregnated with a resin composition comprising resin, the heating being so as to substantially cure the resin, thereby to produce the modified wood product. The method comprises, during the heating of the resin impregnated wood product in the reactor, introducing water into the reactor. A reactor and a modified wood product are also disclosed.

Abstract: An insert for a vehicle wheel having a plurality of spokes which define, in part, an outwardly-facing wheel surface, and further define between adjacent ones of the spokes, a cavity for receiving the insert, in use, the insert comprising: an outer profile of complementary shape to the cavity and arranged to fit securely within the cavity, in use; and a flow redirecting surface which is aerodynamically shaped so as to reduce drag on an adjacent spoke of the wheel, in use.

Abstract: The invention relates to an adapter for driven tools such as drilling or milling tools, for adapting an externally fed driven tool for use in a thru coolant system comprising: a) a cylindrical inner sleeve, b) an outer sleeve adapted to rotate relative to the inner sleeve, c) a delivery pipe to deliver coolant to the outer sleeve, and d) at least one coolant flow channel through the outer sleeve and through the inner sleeve to allow flow of coolant from the delivery pipe to the collet, and e) a seal at one end of the inner sleeve having an aperture to receive the cutting tool whereby to allow the blunt end of the tool to engage the collet, in use coolant can pass through the outer sleeve, through the inner sleeve into the collet, and to the cutting tool whilst said inner sleeve rotates with said machine output spindle and the outer sleeve remains static.
