Floor panels are shown, which are provided with a mechanical locking system including a tongue with rocker arms that allows locking by a vertical turning motion.

Panels are shown, which are provided with a mechanical locking system comprising a separate and flexible tongue allowing connection with a snap action. An outer edge part of the separate flexible tongue comprises a guiding protrusion that facilitates easy disassembly of the panels and that is deformed during locking and / or unlocking.

A fuel nozzle for a gas turbine generally includes a main body having an upstream end axially separated from a downstream end. The main body at least partially defines a fuel supply passage that extends through the upstream end and at least partially through the main body. A fuel distribution manifold is disposed at the downstream end of the main body. The fuel distribution manifold includes a plurality of axially extending passages that extend through the fuel distribution manifold. A plurality of fuel injection ports defines a flow path between the fuel supply passage and each of the plurality of axially extending passages.

The present disclosure relates to a ramp kerb for supporting a transverse edge of a ramp surface and a ramp lip extension having an attachment portion. The ramp kerb comprises a first longitudinally extending channel open at an inner transverse edge of the ramp kerb for receiving a transverse edge of the ramp surface and a second longitudinally extending channel open at the inner transverse edge of the ramp kerb for receiving an attachment portion of the ramp lip extension. The first and second longitudinally extending channels are vertically spaced.

The invention provides an offshore artificial island structure and a construction method suitable for silt foundations. The silt foundation is replaced by block stones and foot guards are provided with block stones. A block stone layer is arranged on the upper part of the block stone replacement layer, and a first First-level sea sand filling layer, gravel cushion and first-level geotextile are set between the block stone layer and the first-level sea-sand filling layer; sand pipes are set near the front section of the top surface of the first-level sea-sand filling layer Sea sand filling in the triangular area is set outside the sand tube bag stack, and a transition layer is set. A second-level geotextile is set between the transition layer and the sea sand filling in the triangular area, and the top of the sand tube bag stack; outside the artificial island in the sea A block stone surface layer is set, and a block stone cushion is set between the transition layer and the block stone surface layer. In the construction of the present invention, there is no need to perform grouting or drainage board consolidation treatment on the silt foundation, which reduces project investment and construction period, and reduces environmental pollution; sand pipe bags and sea sand filling layers are arranged according to the filling height, and the layout is flexible. The type is simple and the construction is convenient.

A damping valve device includes an actuator which carries out an axial displacing movement on a sliding sleeve. The sliding sleeve, along with a fixed valve carrier, forms a slide valve which has two flow directions. The slide sleeve is impinged with damping medium on a front side and on a rear side in an incident flow direction, and the front side of the slide sleeve and rear side of the slide sleeve are impinged hydraulically in parallel by damping medium during the incident flow.

In one aspect of the invention, a floor nailing gun includes a nail magazine; a sleeve component; a nail ejecting component; an elastic component; and a base, where an end face of one end of the nail magazine is provided with at least one threaded hole for fixedly connecting the nail magazine to the base, and the sleeve component, the nail ejecting component, and the elastic component are mounted on the nail magazine, wherein the nail magazine is provided with an L-shaped groove having an L-shaped cross section or a T-shaped groove having a T-shaped cross section, and a boss for preventing nails from jumping up and down is formed at the top of the L-shaped groove or the T-shaped groove.

The invention discloses a flanged groove type FRP (Fiber Reinforce Plastic) plate-concrete combination bridge deck. The flanged groove type FRP plate-concrete combination bridge deck comprises an FRP plate and concrete, wherein the FRP plate comprises a plurality of single groove type FRP plates; every two single groove type FRP plates are connected end to end in an alignment attachment mode of groove shape side rib plates and are spliced into the FRP plate; the concrete is poured onto the FRP plate and covers the FRP plate. The flanged groove type FRP plate-concrete combination bridge deck is simple in structure and convenient to construct, and various stress and configuration requirements on longitudinal and horizontal bridge directions can be better met.

The invention discloses a pulling-rope diverter for inclination of a rope tower. The pulling-rope diverter comprises saddle bodies and rope-strand transition pipes connected by transition flanges, wherein wire distributing pipes arranged in the saddle bodies adopt raindrop-shaped wire distributing pipes; wire-distributing-pipe positioning plates are provided with raindrop-shaped holes; rope-strand guiding sections are arranged between the two ends of the saddle bodies and the transition flanges; each rope-strand guiding section consists of a saddle-body connecting flange, a wire-distributing-pipe transition plate, a guide pipe connecting flange, a guide pipe, a wire pipe, a wire pipe positioning plate and a guide pipe transition plate; the guide pipe is internally provided with the wire pipe positioned by the wire pipe positioning plate; one end of the wire pipe is respectively inserted into a pipe hole arranged on the wire distributing pipe transition plate; the pipe hole arranged on the wire-distributing-pipe transition plate corresponds to the raindrop-shaped hole arranged on the wire-distributing-pipe positioning plate; the wire-distributing-pipe transition plate is connected between the connecting flange and the guide pipe connecting flange; the other end of the wire pipe is inserted into the pipe hole arranged on the guide pipe transition plate at the end part of the guide pipe; and the guide pipe transition plate is arranged in the transition-section flange. The pulling-rope diverter disclosed by the invention has the advantage that the saddle bodies are anchored in the rope tower by adopting a manner of oblique intersection.
