Abstract: A method of minimising distortion in a workpiece is described that includes utilizing a computer system to carry out finite element analysis on a finite element thermo-mechanical model of the workpiece during and after fabrication by additive manufacturing to predict shape distortion and residual stress development in the workpiece, wherein the fabrication includes the fabrication step of depositing multiple layers of a material melted by a heat source along a deposit path on a substrate, and introducing alterations to the workpiece prior to or during fabrication to compensate for the predicted distortion.

Abstract: A patient assist lift (PAL) device comprising a contoured shell which provides many benefits to patients and rescuers. A PAL device reduces or eliminates the risks of injuring a patient during mobilization. A PAL device may be quickly and easily attached to a patient, and supports hips, spine, torso, and neck. Color coded straps encourage proper use of a PAL device. Ergonomic handles and straps reduce or eliminate injury to rescuers during lifting and movement of an injured person. A PAL device enables rescuers to lift and mobilize an injured person from any position and in any situation. A PAL device is especially effective in emergencies in providing a safe and efficient means to secure and move a patient with the least amount of effort while minimizing the risks and discomfort to both patient and rescuer in mobilizing such patient. A smaller PAL device can be used to immobilize children or extremities.

Abstract: A device is provided for hoisting a module for mounting into an overhead space, such as the crown of an aircraft fuselage. The device includes a frame that supports the module, and a lifting device that lifts the first frame to properly place the module. The lifting device includes a frame, attachment devices that attach the frame of the lifting device to overhead support frames, and a driving device that moves the frame of the lifting device up the attachment devices. The frame of the lifting device receives the frame that supports the module as the frame of the lifting device is moved by the driving device.

Abstract: There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.
