Abstract:
A multilayer photovoltaic backsheet comprising a transparent substrate with same polymeric coatings on both sides of the substrate or a different polymeric coating on either side of the substrate. The use of coatings instead of laminated layers provides for a manufacturing process that is faster, has fewer steps, and is more cost effective. Coatings can be tailored to provide excellent adhesion, without the problems of delamination seen in prior art laminated backsheets. The coating for the outer side of the substrate can also be tailored to be softened during module lamination. A patterned blanket or other patterned or textured surface can be pressed against the outer side coating layer during lamination. The pattern or texture is thus transferred to the outer side of the backsheet, which will cause light passing through the backsheet to be diffused. Latent cross-linking reaction can further harden the outer side coating layer to increase the outer side coating layer hardness and to improve its durability.
Abstract:
Abstract of the Disclosure A flexible composite with integral flights is provided and methods for making the same. The composite is made from, for example, silicone rubber, urethane rubber, polytetrafluoroethylene or other polymer. The composites are useful for making articles of manufacture, in particular, conveyor belts for use in high temperature food processing. The conveyor belts are an improvement over the prior art in that they prevent slippage of the articles conveyed, may be manufactured at low cost and are easy to clean.
Abstract:
A connector and tubing assembly including a multi-lumen molded connector having at least three flexible tubes also molded into the connector. The connector may be nullYnull shaped and include three flexible tubes. A process of making the connector and tubing assembly involves forming a first part of the connector with two tubes molded therein and then removing an internal mold member prior to molding the final connector portion and third tube in place.
Abstract:
The disclosure relates generally to a cell culture apparatus and a cell culture method. One aspect of the disclosure provides a perfusion cell culture bag comprising one or more polymer films, having edges bonded together to form edges around an undivided interior compartment of the bag; first and second ports each formed in an exterior surface of the bag; first and second liquid-permeable tubes each extending into and in fluid communication with the interior compartment of the bag and operatively coupled to a respective port; and a third port formed in an exterior surface of the bag, the third port being in fluid communication with the interior compartment of the bag; wherein the first tube comprises a first inner support structure defining a central lumen of the tube and a first outer filter layer surrounding the first inner support structure.
Abstract:
A rotary shaft seal including an annular body having an aperture defining a central axis and an inner surface; a shaft disposed within the aperture of the annular body; and a sealing element positioned at least partially between the shaft and the annular body, where the sealing element is configured to form a seal between the annular body and the shaft, where the sealing element includes a body having a U-shaped or a V-shaped cross-section including a plurality of lips, where at least one lip of the sealing element is fixed to at least one of the shaft or the annular body, and where a cavity exists between at least one of the plurality of lips and at least one of the shaft or the annular body.
Abstract:
Systems and methods include providing a seal for an assembly. The seal includes a jacket having a base, an inner sealing leg, and an outer sealing leg, and further includes a spring disposed within the jacket between and in contact with the inner sealing leg and the outer sealing leg. The spring includes an annular support ring disposed within the spring. The support ring biases an outer diameter (OD) of the spring towards the outer sealing leg of the jacket to maintain contact pressure between the inner sealing leg of the jacket and the shaft of the assembly. The support ring controls thermal shrinkage of the spring and the outer sealing leg to maintain a seal between a housing and a shaft of the assembly when the assembly is operated at cryogenic temperatures.
Abstract:
A seal including: annular jacket including a body including a heel, a first lip, and a second lip defining an annular recess, the first lip including an arcuate exterior portion, and having a thickness, WFL, and a length LFL; and an annular energizer disposed within the annular recess, adjacent to at least one of the first lip and the second lip, wherein the heel comprises a cutout portion, and wherein the ratio of LFL:WFL is greater than 2.
Abstract:
A method of forming a three-dimensional body from a mixture, wherein the mixture can comprise dispersed solid polymeric particles and a curable binder. In a particular embodiment the solid polymeric particles can be fluoropolymeric particles. The method can include at least partial removal of the cured binder and sintering, to obtain a sintered polymeric three-dimensional body. In one embodiment, the sintered three-dimensional body can be PTFE.
Abstract:
A linear motion assembly including: a first component; a second component; and a sliding member disposed between the first and second components; and a retention system adapted to retain the sliding member between the first component and the second component, where the retention system includes a retention frame and at least one spring element, where the sliding member is disposed between the retention frame and the spring element, where the spring element provides a biasing force on the sliding member.
Abstract:
A profile includes: a sidewall, a lumen for a fluid path, and an end, the profile including a thermoset material, wherein the profile includes a sealed end without an external bonding material, wherein the sealed end withstands a seal integrity pressure test of at least 1 psi, such as at least 5 psi, such as at least 10 psi, such as at least 15 psi, or even at least 20 psi air pressure for about 30 minutes under dry and wet conditions.
