Abstract: A rebar tie wire reel (110) for a reinforcing bar binding machine has a first flange (118), a second flange (120) spaced from the first flange, a hub connecting the first and second flanges and a wire (124) wound around the hub. The first flange (118) has an outwardly facing major face (134) and an outer periphery. The outer periphery is defined by a plurality of edges (170, 172, 174, 176). The plurality edges include a first edge (170) and a second edge (172) that are configured such that, in use, an amount of rotation of the rebar tie wire reel can be determined using signals provided by a movable element of a contact sensor when during rotation of the wire reel, the first edge, major face and the second edge successively travel past the movable element.

Abstract: A fuel canister valve assembly has a valve cup, a valve stem housing connected with the valve cup and defining a seal housing containing a valve seal and a valve stem having an inner end housed in the valve stem housing and extending through the valve seal to an outer end disposed externally of the valve stem housing. The valve stem housing has an outer periphery provided with at least one side passage defining a flow path along the outer periphery.

Abstract: A drilling device for producing undercut holes. The drilling device includes a drilling tool having an axis of rotation and a cutting portion arranged such that the cutting portion drills a hole with a longitudinal axis that is radially offset with respect to said axis of rotation and a centering device operable to apply a lateral force to said drilling tool for moving said axis of rotation towards said longitudinal axis to cause said cutting portion to form an undercut in a said hole.
