A sealing jaw assembly for a sealing unit, and in particular an arrangement for suspending a sealing jaw in a socket is disclosed. The arrangement is based on a first and a second spring arrangement wherein the action of the first spring arrangement onto the sealing jaw may be activated and deactivated.

The present disclosure is directed to a system and method for lifting and/or removing a rotor blade to and from a wind turbine. In one embodiment, the system includes an up-tower pulley mounted on an up-tower location of the wind turbine, first and second ground winches, a pulley cable from the first ground winch over the up-tower pulley and attached to the rotor blade, a guide line attached between an up-tower location of the wind turbine and the second ground winch, a guide pulley mounted on the guide line, and a guide cable from the guide line over the guide pulley to the rotor blade. Thus, the guide pulley is configured to move along the guide line during lifting and removing of the rotor blade so that the guide cable can control an orientation of the rotor blade relative to the tower during lifting and removing of the rotor blade.

The invention relates to a chromatography column frame comprising at least two legs, a support arrangement connected to said at least two legs, and a holder means connected to said support arrangement. Said holder means is arranged to releasably hold an adaptor rod of a chromatography column, so that the adaptor rod is prevented to move in a horizontal direction and so the adaptor rod is allowed to move in a vertical direction. The invention also relates to method of conducting maintenance on and packing of a chromatography column.

A demolition hammer is provided that includes a housing that is reversible and a plurality of interchangeable wear plates. The demolition hammer may include a housing a housing having a first wall and a second wall opposite the first wall, and a power cell disposed within the housing, the power cell having a front face, wherein the housing is reversible such that the housing can be used with the power cell in a first orientation in which the front face faces the first wall and a second orientation in which the front face faces the second wall.

A system and method of altering the air conditioning system in an aircraft so that the air conditioning system is electrically powered rather than engine powered. The aircraft is rid of the air conditioning components that are dedicated to the engine powered system. A new electric compressor, evaporator and condenser blower assembly are then installed. Heat exchanger units are installed in the areas of the aircraft that are to be cooled. The new air conditioning system has two circulatory loops. In a refrigerant loop, refrigerant is circulated between the electric compressor, evaporator and condenser. This cools the evaporator. The evaporator is then used to cool circulating liquid coolant. The coolant is circulated to the heat exchange units.

A gas turbine engine includes a core, a first annular portion, a rail, and a second annular portion. The first annular portion is stationary and adapted for partially surrounding an engine core. The first annular portion includes a fore pylon connecting portion, and a fore bi-fi. The rail is coupled to the fore pylon portion and extending in the aft direction from the stationary portion. The second annular portion is arranged aft of the first portion and coupled to the rail. The second annular portion is movable along an engine core centerline between a closed position and at least one open position. The second annular portion comprises an aft bi-fi configured to engage with the fore bi-fi when the gas turbine engine is in the closed position.

A method is disclosed. The method provides an assembly that comprises a first drum-cylinder having an inner periphery surface and a gear assembly, wherein a portion of the gear assembly is in contact with the inner periphery surface; and decouples the gear assembly from the first drum-cylinder by crushing at least a portion of the first drum-cylinder.

A gas turbine engine nacelle includes a first annular portion that is stationary and adapted for partially surrounding an engine core. The first annular portion includes a fore pylon connecting portion. A rail is coupled to the fore pylon connecting portion and extends in the aft direction from the first annular portion. A second annular portion is positioned aft of the first portion and coupled to the rail. The second portion is movable along an engine core centerline between a closed position and at least one open position. The second annular portion is configured to engage with the first annular portion in the closed position, thereby providing access to the engine core. A mating axial groove and rib connection is located between the first annular portion and the second annular portion.

The present disclosure provides a back reamer roller cone that is configured so that the bearings assemblies therein can be relatively easily removed and replaced. Methods of replacing the bearing assemblies in a back reamer are also provided.

A link member for a tyre chain, comprising a body including a cavity for receiving a portion of a ring element therein, the body also including an opening for inserting the ring element into the cavity, said body further being adapted to receive a retaining member for closing the opening and retaining the ring element in the cavity.
