Abstract:
Provided herein are methods and systems for rapid testing of films used in the manufacture of bioprocess bags. The methods described herein allow for determination of resistance to flexural fatigue while mimicking actual conditions in bioprocesses such as flexion and subsequent fatigue and failure of a bioprocess bag made of a film when it is placed on a rocking platform.
Abstract:
The present invention provides an insulated fluid conduit useful in facilities in which a hot fluid susceptible to deleterious phase changes in response to heat loss to a cold environment is transported. Such conduits may be particularly well suited to improve thermal control in subsea hydrocarbon production operations in which hot production fluids may undergo deleterious phase changes as a result of heat loss to the cold subsea environment. The fluid conduit includes an insulating material containing a silicone rubber and a phase change material such as octadecane. One or more barrier layers inhibit migration of the phase change material from the insulation layer and into the environment. In one or more embodiments, the phase change material is present as a microencapsulated phase change material.
Abstract:
Waveguides having improved illumination distribution and output luminance variation and lighting systems utilizing such waveguides are disclosed. The lighting systems generally include a light source which is optically coupled to a waveguide to distribute the light. The waveguides include one or more headlighting reduction regions and one or more output intensity shaping regions that work together to improve the distribution of light and reduce the effects of headlighting. The headlighting reduction regions may be integrated with the output intensity shaping region or may be an independent section.
Abstract:
A method of making a master cure tool for applying a texture to an aerodynamic surface includes the steps of: providing a foil which is metallic and has a textured surface; applying the foil to a forming surface of a rigid forming tool which is compound curved, and plastically deforming the foil to conform to the forming surface, so as to define a foil layer; annealing the foil layer using heat or a combination of heat and pressure; and bonding the foil layer to a support body, thereby defining the master cure tool.

Abstract:
An additive manufacturing system includes a laser device, a build plate, a first scanning device, and an alignment system. The laser device is configured to generate a laser beam. The build plate has a position relative to the laser device. The first scanning device is configured to selectively direct the laser beam across the build plate. The laser beam generates a melt pool on the build plate. The alignment system includes a fiducial marks projector configured to project a plurality of fiducial marks across the build plate. Each fiducial mark has a location on the build plate. The alignment system also includes an optical detector configured to detect the location of each of the fiducial marks on the build plate. The alignment system is configured to detect the position of the build plate relative to the laser device.
Abstract:
A carrier for growing stem cells is provided, the carrier comprises a substrate comprising one or more outer surfaces; and a hydrophilic, water soluble coating material disposed and dried on one or more of the outer surfaces. The carrier comprises one or more structured indentations on one or more of the outer surfaces, wherein the carrier has a length at least about 0.2 mm, a width at least about 0.2 mm, and a height in a range from about 0.05 mm to 1.2 mm and each of the structured indentations has a major axis in a range from about 0.1 mm to 0.5 mm, a minor axis in a range from about 0.1 mm to 0.5 mm and a depth in a range from about 0.025 mm to about 0.5 mm. A method of culturing stem cells and stromal cells using the same carrier are also provided.
Abstract:
The present invention provides an insulated fluid conduit useful in facilities in which a hot fluid susceptible to one or more deleterious phase changes in response to heat loss to a cold environment is transported. Such conduits may be particularly well suited to improve thermal control in subsea hydrocarbon production operations. The fluid conduit includes an inner first insulating layer containing a first polymer matrix, and a first phase change material undergoing a phase change at T1. The fluid conduit includes an outer second insulating layer containing a second polymer matrix, and a second phase change material undergoing a phase change at T2, wherein T1 is greater than T2. One or more barrier layers inhibit migration of the phase change material from the insulation layers and into the environment. In one or more embodiments, the phase change material is present as a microencapsulated phase change material.
