A quick coupler (1) for attaching a tool (2), comprising an attachment bracket with two parallel attachment pins (3a, 3b), to an earth moving vehicle, where the quick coupler (1) comprises a frame (4) with a first cutout (5) and a second cutout (6) arranged substantially perpendicular to each other, which are adapted to cooperate with the respective attachment pin (3a, 3b) of the tool (2). The quick coupler (1) further comprises at least one, in relation to the frame (4) moveable locking arrangement (9), adapted to delimit the second cutout (6) in a direction parallel to the first cutout (5), whereby one of the attachment pins (3aq, 3b) of the tool is locked in the second cut-out (6) and at least one locking segment (18a, 18b) arranged to be rotated in relation to the frame (4) in at least a first and a second direction between different positions, whereby the locking segment (18a, 18b) in at least one position delimit the first cut-out (5) and locks the second of the attachment pins (3a, 3b) of the tool.

One embodiment of a gun configured with the soft recoil system comprises a plurality of recoiling parts that initially moves in the direction of the projectile being fired before moving in a direction opposite to that of a projectile during the firing of the round. The soft recoil system throttles the movement of the recoiling parts such that the energy expended during the firing of the round is spread over a longer time period and a longer distance than would normally occur. The soft recoil system stores at least a portion of the energy transferred to the recoiling parts and the user may selectively release at least a part of that portion of energy to offset the energy imparted to the gun during the firing of the next round.

A piston unit of a working cylinder has first and second coupling partners. The first coupling partner is a piston. The second coupling partner a piston rod. The piston rod is inserted axially into the piston. Each of the coupling partners has an annular groove. The groove of the piston rod is an external groove. The groove of the piston is an internal groove. The grooves of the coupling partners lie opposite one another. The unit has a coupling strand which engages in the grooves of the coupling partners and is placed into engagement by insertion into an annular groove gap defined by the grooves. The engagement of the coupling strand in the grooves produces a form-locking connection between the partners. The piston rod is oversized in relation to the piston and provides an additional frictional connection.

A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.

A set of panels including a first panel with a first main plane and a second panel with a second main plane with a second main surface. The first and second main planes are essentially perpendicular in a locked position. The first and the second panel include a locking device for locking a first edge of the first panel to a second edge of the second panel. The locking device includes an edge groove wherein the edge groove includes a tongue, which is configured to cooperate with a tongue groove of the first panel, in a locked position, for locking the first and the second edges in a first direction which is perpendicular to the first main plane. A first groove surface of the edge groove cooperate with second main surface to lock the first and second panel in a second direction which is perpendicular to the second main plane.

A set of panels includes a first panel having a first main plane and a second panel having a second main plane. The panels are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel. The mechanical locking device includes an edge section groove at the first edge, wherein an edge section of the second edge is insertable into the edge section groove. A flexible tongue is arranged in an insertion groove provided in the edge section groove, and cooperates with a tongue groove provided at the edge section of the second panel. A first thickness of a core material between the edge section groove and the outermost surface of the first edge is greater than a minimum second thickness of a core material of the edge section of the second panel.

A set of panels including a first panel with a first main plane and a second panel with a second main plane with a second main surface. The first and second main planes are essentially perpendicular in a locked position. The first and the second panel include a locking device for locking a first edge of the first panel to a second edge of the second panel. The locking device includes an edge groove wherein the edge groove includes a tongue, which is configured to cooperate with a tongue groove of the first panel, in a locked position, for locking the first and the second edges in a first direction which is perpendicular to the first main plane. A first groove surface of the edge groove cooperate with second main surface to lock the first and second panel in a second direction which is perpendicular to the second main plane.

An assembly of a gas turbine engine includes a first component, a second component disposed radially outboard of the first component. The second component includes one or more flange segments circumferentially spaced apart by one or more flange openings. Each flange segment includes a groove extending radially outwardly from a radially inboard surface of each flange segment between the first component and the second component. A retaining wire extends along each groove and is located radially between the first component and the second component to axially retain the second component to the first component. A radial cross-sectional size of the retaining wire is greater than a radial gap between the radially inboard surface of the second component and the first component.

A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.
