A system and method for welding thermoplastic components by positioning and moving a heated plate between the components to melt their respective faying surfaces, and as the plate moves, pressing the components together so that the melted faying surfaces bond together as they cool and re-solidify, thereby creating a composite structure. The plate has a heated portion which is positioned between and heated to melt a portion of the first and second faying surfaces. A manipulator mechanism moves the plate along an interface from between the portion to between a series of subsequent portions of the first and second faying surfaces, thereby welding the thermoplastic components along the entire interface to create the composite structure. The heated portion may contact the faying surfaces and melt them through conduction, or may be suspended between them and melt them through radiation and convection.

An optical system can include a receiver secured to a first optical component and a flexure arrangement secured to a second optical component. The flexure arrangement can include a plurality of flexures, each with a free end that can extend away from the second optical component and into a corresponding cavity of the receiver. Each of the cavities can be sized to receive adhesive that secures the corresponding flexure within the cavity when the adhesive has hardened, and to permit adjustment of the corresponding flexure within the cavity, before the adhesive has hardened, to adjust an alignment of the first and second optical components relative to multiple degrees of freedom.

A method for connecting at least two structural parts of an orthopedic component, wherein the structural parts are retained in an orienting device while oriented in relation to each other, and an intermediate space thus being formed between the structural parts. The orienting device and the structural parts together form a cavity, which has a flow connection to at least one feed connection, via which an adhesive for adhesively bonding the structural parts is introduced into the cavity.

The present disclosure provides a method for bonding a structural component to a rail. The method includes (a) positioning a bonding agent in a plurality of blind holes defined in a bottom surface of the rail, (b) positioning a spacer in each of the plurality of blind holes, (c) positioning the structural component into the channel such that the structural component rests on each spacer, wherein a first gap is defined between the structural component and the bottom surface of the rail, a second gap is defined between the structural component and a first sidewall of the rail, and a third gap is defined between the structural component and a second sidewall of the rail, and (d) injecting the bonding agent into the channel such that each of the first gap, the second gap, and the third gap includes the bonding agent.

A method for repairing aircraft window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.

A method of applying a lid (1) onto a neck (9) of a container (10), the lid (1) having a side wall (3) extending around an axis and an end wall (2) extending transversely to said axis, comprises the following steps: —positioning the lid (1) onto the neck (9); —exerting on the end wall (2) a force directed towards the container (10), so as to level the lid (1) on the neck (9); —screwing the lid (1) onto the neck (9) by rotating the lid (1) in a screwing direction.

A composite vehicle driveshaft assembly includes a composite tube and a yoke bonded to one of the ends of the tube. The yoke has an inner sleeve that is concentrically received in the end of the tube. The sleeve has an outer peripheral surface that faces the inner peripheral surface of the tube with a cavity formed therebetween. An adhesive injection passage is formed in the yoke and extends at an acute angle from an inlet that is formed in an axial surface of the yoke to an outlet that is formed in the outer peripheral surface of the sleeve and that opens into the cavity. Also disclosed is a method of bonding a yoke of such a driveshaft assembly to a composite tube.

A method of making an array of vapor cells for an array of magnetometers includes providing a plurality of separate vapor cell elements, each vapor cell element including at least one vapor cell; arranging the vapor cell elements in an alignment jig to produce a selected arrangement of the vapor cells; attaching at least one alignment-maintaining film onto the vapor cell elements in the alignment jig; transferring the vapor cells elements and the at least one alignment-maintaining film from the alignment jig to a mold; injecting a bonding material into the mold and between the vapor cell elements to bond the vapor cell elements in the selected arrangement; removing the at least one alignment maintaining film from the vapor cell elements; and removing the bonded vapor cells elements in the selected arrangement from the mold to provide the array of vapor.

Method of bonding a shear web (50) to a wind turbine blade shell (75) and the obtained blade, wherein the shear web (50) comprises a web and a mounting flange (56) oriented transverse to the web (50). The method involves: providing a seal (66, 68) on the mounting flange (56) of the shear web (50) such that when the mounting flange (56) is positioned against the blade shell (75), a cavity (76) is defined by the seal between the mounting flange (56) and the blade shell (75). The air of the cavity (76) is then evacuated and adhesive is injected into the cavity (76). The use of pieces (80) to keep the distance between the mounting flange (56) and the blade shell (75) is preferred.

A blade shell part for a wind turbine blade and a wind turbine blade are disclosed. The blade shell part is made of a composite structure comprising a reinforcement material embedded in a polymer matrix, the blade shell part extending from a tip end to a root end, wherein the blade shell part comprises: a blade shell body with a leading edge and a trailing edge, and a first glue flange extending from the leading edge and having a first glue flange edge and a first glue surface with a first width, wherein the first glue flange is provided with one or more spacer elements. Further, a method of manufacturing a wind turbine blade is described.
