Abstract: An insulation product for a pipe-in-pipe pipeline having a clamshell assembly formed of a lightweight, semi-rigid material forming an annular cylinder when closed around a pipe and configured to fill an internal space of a pipe-in-pipe pipeline system. The annular cylinder is split into multiple sections, each section having an internal void filled with insulating material, such as aerogel. The multiple sections are connected by flexible portions or hinges. The aerogel insulation is contained within a section of the annular cylinder. The clamshell assembly is quickly and simply installed to a pipeline and accepts a wide variety of insulation types and forms to reduce production time and expense.

Abstract: A roofing membrane with improved edge flexibility comprises a base reinforcement layer having a width W, a top reinforcement layer bonded to the base reinforcement layer, and a matrix coating the top reinforcement layer bonded to the base reinforcement layer. The top reinforcement layer has a width of about 80%±10% of width W. The matrix comprises one or more materials selected from the group consisting of bitumen, modified bitumen, one or more polymeric materials, and mixtures thereof.

Abstract: A roofing membrane temperature indicator is provided for preventing the installation of a roofing membrane or roofing membranes at a temperature below a minimum recommended installation temperature for the roofing membrane(s) and/or a minimum recommended installation temperature for the roofing membrane(s) for a particular installation procedure. The membrane temperature indicator is visibly associated with the roofing membrane(s) and includes a thermochromic indicator having a first color at temperatures below a designated temperature and a second color visibly different from the first color at and above the designated temperature. The designated temperature at which the color of the membrane indicator changes is at or above a minimum recommended installation temperature for the roofing membrane(s) and/or a minimum recommended installation temperature for the roofing membrane(s) for a particular installation procedure.

Abstract: An optical device and method of manufacture are disclosed. The optical isolator includes a substrate comprising a magnetic material such as a Garnet. Respective sets of essentially parallel conductors are selectively formed on both major surfaces of the substrate. The set on one surface is at a selected angle with respect to the set on the other surface.

Abstract: An optical device and method of manufacture where the device includes a housing within which is a wavelength division multiplexer component. An optical fiber is coupled directly to the component without any splices. The fiber includes a dopant which causes light from the component to be amplified as it propagates therethrough.
