Flexure arrangements for optical components
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.
AEROSPACE COMPONENT JOINTS FOR AIRCRAFT AND RELATED METHODS
The aerospace component joints comprise a first component member comprising a first bonding face, a second component member comprising a second bonding face, one or more bond-enhancing features, and an adhesive layer forming a bond between the first and second bonding faces. The one or more bond-enhancing features comprises a plurality of reinforcing protrusions integral with the first component member, projecting from the first bonding face through the adhesive layer, and into the component member and/or one or more adhesive-receiving recesses defined in the first or second bonding faces and filled by the adhesive layer. The methods of preparing a component member for an aerospace component joint comprise integrating one or more bond-enhancing features into the component member. The methods of forming the aerospace component joint comprise positioning and adhesive-bonding the first bonding face to the second bonding face, and integrating the bond-enhancing feature(s) into the aerospace component joint.

APPARATUS, METHOD AND SYSTEM TO TEMPORARILY HOLD A WORKPIECE DURING MANUFACTURING USING ADHESIVE ATTACHMENT
A method and system temporarily holds a workpiece, most suitably an aero engine turbine blade element during manufacture. The workholding system includes a support body with a contoured body surface, complementary to a workpiece surface, formed of a transparent material to define a bonding zone. The support body is supported by a base to form a workpiece shuttle, and a bond station receives the workpiece shuttle. Complementary zero-point locating elements on the shuttle and station assure accurate positioning. The bond station further has workpiece locating elements configured to accurately position the workpiece on the shuttle in a predetermined position relative to the zero-point locating elements of the shuttle, thereby compensating for shuttle-to-shuttle variance. An adhesive, such as a UV curable adhesive, is applied to the bonding zone and cured by UV through the transparent material, thereby fixing the workpiece in the predetermined position.

END EFFECTORS AND METHODS FOR ADHESIVELY ATTACHING A FIRST PART TO A SECOND PART
An end effector, for adhesively attaching a first part to a second part, comprises a support and a first nozzle, coupled to the support and movable relative to the support, and a second nozzle, coupled to the support and movable relative to the support. The first nozzle comprises a first-nozzle body, comprising a first-nozzle-body outlet port and a first-nozzle separator plate, extending from the first-nozzle body. The second nozzle comprises a second-nozzle body, comprising a second-nozzle-body inlet port and a second-nozzle separator plate, extending from the second-nozzle body. The end effector further comprises a roller, coupled to the support, rotatable relative to the support about a roller axis, and located between the first nozzle and the second nozzle.
ASSEMBLY FOR THE FULL-SURFACE ADHESIVE BONDING OF SUBSTANTIALLY CONGRUENT ADHESIVE-BONDING SURFACES OF A FIRST AND A SECOND JOINING PARTNER
The invention relates to an assembly for adhesively connecting substantially congruent gluing surfaces of a first and second joining partner over their full surface, comprising: the first joining partner (1); the second joining partner (2); an adhesive layer (3) of a polar, flowable adhesive applied to the gluing surface (1a) of the first joining partner (1); means (8) for holding the second joining partner (2) above the adhesive layer (1a) of the first joining partner (1), such that the gluing surface (2a) of the second joining partner (2) faces the adhesive layer (3) on the first joining partner (1) and is disposed so as to be spaced therefrom across an air gap (5), and the spacing defined by the air gap (5) between the first joining partner (1) and the second joining partner (2) is dimensioned in such a way that a capillary volume is formed; means (7) for generating an electric field (10) in order to cause, by means of electric influence, a local charge displacement (11) on and/or in the second joining partner (1), and the charge displacement (11) is suitable for attracting the polar adhesive in such a way that it wets the gluing surface (2a) of the second joining partner (2) first in the area of the local charge displacement (11), wherein the means for generating the electric field comprise an electrode (7), which is disposed on the side of the second joining partner (2) facing away from the gluing surface (2a) and is electrically insulated from said partner (2).
