Joining method for wind turbine blade shells
11203167 · 2021-12-21 · ·

A method of manufacturing a wind turbine blade is described, the blade being formed from at least a pair of blade shells being joined together. For at least a portion of the wind turbine blade, the blade shells are joined by an overlamination applied between the edges of the blade shells, thereby substantially reducing or eliminating the need for a structural adhesive to join the blade shells, particularly in the area of the leading edge of the blade or the root region of the blade trailing edge. The overlamination can be formed from the same material as the blade shells themselves, thereby minimising the possibility of structural faults or cracks due to differences in materials or stiffness levels at the interface between the blade shells.

METHOD OF FORMING A SPLICED JOINT IN A HANDRAIL OR OTHER ELONGATE ARTICLE

A handrail has a thermoplastic body having a generally C-shaped cross section, a stretch inhibitor in the thermoplastic body above a T-shaped slot and a slider fabric layer. The handrail includes first and second end portions, each comprising a forward part extending from an end surface of the end portion and a rear part adjacent the forward part. A method of forming a joint can include: providing cuts to separate a top section of the thermoplastic body from a base section including shoulder portions; for each end portion, removing at least shoulder portions from the forward part thereof, to leave a central portion including a forward part at the slider fabric layer and a layer of thermoplastic; cutting the forward parts to a required shape; and assembling the first and second end portions together to form a spliced joint for moulding.

20220203625 · 2022-06-30 ·

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

Systems and methods for manufacturing a microfluidic rotor device

Described herein are various embodiments directed to rotor devices, methods, and systems. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include bonding a first layer and a second layer using two-shot injection molding. The first layer coupled to the second layer may collectively define a set of wells. The first layer may be substantially transparent. The second layer may define a channel. The second layer may be substantially absorbent to infrared radiation. A third layer may be bonded to the second layer using infrared radiation. The third layer may define an opening configured to receive a fluid. The third layer may be substantially transparent. The channel may establish a fluid communication path between the opening and the set of wells.

Systems and Methods for Joining a First Structure and a Second Structure with Vacuum Dispersion Process

An example method of joining a first structure and a second structure is described that includes forming a bond cavity between a first structure and a second structure, placing a semi-permeable breather material at one or more exits of the bond cavity, placing a vacuum bag around the bond cavity and the semi-permeable breather material, evacuating the bond cavity via a vacuum port and forcing adhesive into the bond cavity via an adhesive port while the bond cavity is evacuated, and curing the adhesive via one or more heaters to bond the first structure to the second structure.

IMPROVEMENTS RELATING TO THE SEALING OF PIPE LINERS
20220186871 · 2022-06-16 ·

The present invention provides a method of manufacturing a pipe liner for lining the inside of a pipe, for example a water or sewerage pipe requiring repair. The pipe liner is mainly formed of a fabric sleeve, or a plurality of fabric sleeves, and comprises a fluid-proof barrier coating on the inside surface of the pipe liner. The method involves arranging a strip of carrier material comprising a liquid sealant inside the fabric sleeve of the pipe liner and in registration with two opposing side edges of the sheet of fabric, facing an inner barrier coating of the fabric sleeve. The method can advantageously provide such a pipe liner with an inner barrier coating without everting the pipe liner after manufacture. The present invention may also provide a way of avoiding internal cross-welding of said pipe liners and a method for testing the integrity of the barrier coating of said pipe liners. The present invention also provides an apparatus for carrying out these methods.

TAPE LAYUP APPARATUS AND TAPE LAYUP METHOD

Label web with longitudinally-spaced arrays of double-sided adhesive labels
11341869 · 2022-05-24 ·

A label web and method utilize a substrate, first and second longitudinally spaced label arrays each including two or more double-sided adhesive labels removably attached to the substrate, and a peelable protective covering web extending generally coextensive with the substrate. The label arrays and the peelable protective web are configured such that the peelable protective web is selectively removable to expose the first label array while remaining removably attached to the second label array, with both the first and second label arrays remaining removably attached to the substrate, to thereby facilitate removal of all labels in the first label array as a group while the peelable protective covering web remains in place over the second label array.
