Abstract: A power tool for joining a deformable element having a threaded shaft to a workpiece. The joining tool comprising a threaded dowel adapted to receive the threaded shaft and rotatably within the housing. A nose is arranged around the threaded dowel, and the dowel is slidably movable relative to the nose. A motor drives a drive train to rotate the threaded dowel. A hydraulic system drives another drive train to move the threaded shaft and compress the deformable element. The joining tool includes a sliding unit. The nose is attachable to the sliding unit, and in an attached position the nose is slidably connected to the housing so that the hydraulic system may move the nose axially to compress the deformable element.

Abstract: Power tool for crimping or cutting and object, the tool having vents in the tool housing for enabling airflow wherein such vents have a partition member extending across them for restricting liquid water and dust ingress, and method of assembly. Power tool for crimping or cutting an object, the tool having a switch wherein the switch is provided on a support that is clamped between opposing tool housing portions for forming a seal to restrict the ingress of liquid water into the tool housing interior via the switch, and method of assembly. Power tool for crimping or cutting an object, the tool having an arrangement of light emitting elements directed towards an operative part of the tool for indicating operational information to a user without requiring the user to remove their gaze from the operative part of the tool in use.

Abstract: The invention relates to a device for fixing an electrical connection terminal to a support having an opening extending between opposed front and rear faces, the device comprising: a bush for location within the opening of the support and provided with opposed front and rear ends between which extends a through-hole, the bush having a first deformation region configured for lateral expansion; a dowel configured for forced insertion into the through-hole so as to cause deformation of the bush, the dowel being provided with connection means engageable with a connector to facilitate the forced insertion of the dowel into the bush and to facilitate fastening of a terminal to the support; characterised in that the bush includes a second deformation region configured for axial contraction and lateral expansion upon forced insertion of the dowel in the bush.

Abstract: An apparatus for restricting a contact head of a catenary grounding device unintentionally falling from a catenary in use that is connectable to the contact head. The apparatus forming part of a contact head of a catenary grounding device for restricting the contact head unintentionally falling from a catenary in use.

Abstract: This invention relates to an earthing bond seal for sealing between a flanged bush of an earthing bond and a substrate with which the flanged bush is to form an electrical connection, the seal comprising: an upper surface for engagement with the flange of the bush; a lower surface for engagement with the substrate; and an opening extending between the upper and lower surfaces, wherein the upper surface is provided with a first recess configured to receive the flange of the bush.

Abstract: A pressure relief valve for a hydraulic press tool, the pressure relief valve having a valve body, a fluid return channel, a needle and a seat, and the needle is movable between a closed position, in which the needle is in contact with the seat to block the channel, and an open position, wherein the needle is at a distance from the seat to allow fluid to flow in the channel, and the fluid flow then causes movement of the seat away from the needle and completes the opening of the fluid return channel.
