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 system for out of autoclave bonded repairs which including a fixing structure (1) to the composite area to be repaired, including a frame (4) and fixing parts (5, 19) attached to the frame (4), a movable structure (2) able to be attached either to the fixing structure (1) or to the patch manufacturing table (3), which includes three shafts (6, 6, 6) and three engines (7, 7, 7) configured to be able to move the tooling support in the three axes X, Y and Z, and a tooling support of either scanning tool (9), milling tool (10), patch cutting tool (11) or composite patch handle tool (11), and a patch manufacturing structure (3).

A cut-in fitting has a flange hub, a flange ring, a central body, a first gasket, a second gasket, a split flange hub, a split flange ring and a band clamp.

A microfluidic refill includes a reservoir having a hollow body and an opening; a transport member in fluid communication with the reservoir; and a lid enclosing the opening of the reservoir. The lid is in fluid communication with the transport member. The lid comprises a rigid microfluidic delivery member. The rigid microfluidic delivery member includes a die and electrical traces that are in electrical communication with the die, wherein the electrical traces terminate at electrical contacts, wherein the electrical traces are disposed on only one plane. The die has a fluid chamber in fluid communication with the transport member at an inlet of the fluid chamber and with an orifice at an outlet of the fluid chamber and.

A patch for a structure has a rework area with an inconsistency formed therein. The patch comprises a patch body having at least two regions including a fail-safe region and a safe-life region encompassing the fail-safe region. The safe-life region has a mode I interlaminar fracture toughness that is less than the mode I interlaminar fracture toughness of the fail-safe region.

A method to create a temporary access opening in a drywall of a wall structure to access the area behind the wall structure to perform a type of work and to simplify the process of closing of the temporary access opening after completion of the work. A tool to simplify the creation of the temporary access opening is securely attached to the drywall permitting the drywall to be cut. A cutting tool will be used to cut the drywall along the sides of the tool at a certain angle and that angle will allow the cutout drywall piece to be reused to close the temporary access opening without using any supporting material otherwise required to be placed behind the wall to prevent the extracted piece from falling behind the wall structure during the closing step.

An axle mounted spare tire assembly is disclosed for use in replacing a damaged vehicle tire or tire support structure to permit a vehicle to then travel to a vehicle repair shop. The apparatus is comprised of a saddle which surrounds and bolts onto a vehicle's axle. A support tire is mounted below the saddle on a self-locking axle and will rotate as the vehicle is driven. The saddle is provided with a plurality of bolts to facilitate attachment to round, U-shaped, and square vehicle axles. The saddle is also equipped with a detachable handle to allow for ease of attachment and transfer of the assembly to and from the damage site.

The present invention is an improved method and assembly for repairing a pipe or the junction of two pipes, such as sewer pipes. The assembly includes a launcher device having a launcher device body, a launcher device opening disposed on the launcher device body, and a main bladder substantially surrounding the launcher device body. The main bladder includes an opening that substantially aligns with the launcher device opening. The assembly further includes an absorbent liner and a lateral bladder having a tubular lateral bladder body portion and a flange portion. The flange portion of the lateral bladder is attached to the exterior of the launcher device body. A method of using the assembly includes impregnating the liner with resinous material; inserting at least a portion of the liner into the lateral bladder; inflating the bladders; pressing the liner against the pipe; and allowing the resinous material to cure and harden.

A method for use when retrofitting a panel of a storage compartment having a mechanical latch assembly with an electric latch assembly includes removing the mechanical latch assembly from the panel of the storage compartment; and preparing the panel of the storage compartment to receive a potted insert. The preparation may include defining and marking a location to receive the potted insert. The method may include removing a portion of the panel to define a potted insert cavity and inserting the potted insert through the potted insert cavity of the panel. The method may also include applying at least one of a potting compound and an adhesive to bond the potted insert to the panel and coupling a portion of the electric latch assembly to the potted insert.

An apparatus and method for servicing a combustion liner in a combustion case of a turbine is provided. The apparatus includes an elongated bar having a handle at one end and a force applying member at an opposing end of the elongated bar. An attachment member is configured for attachment to a flange of the combustion case. The attachment member is also configured for pivotal attachment to the elongated bar. The apparatus is configured to apply a radially outward force on a downstream portion of the combustion liner when a radially inward force is applied to the handle.
