A sealant is provided for use on an aircraft or other vehicle. The sealant may be used with a gasket. The sealant is a perimeter seal that comprises a polyurea member. The polyurea member is a self-curing, two-component mix. It may cure to a hardness in the range of about 40 to 100 (Shore A). It may maintain an adequate peel strength to withstand multiple thermal and pressure cycling, and may have a working life, wherein it may be shaped, of less than about eleven minutes.

A process for preparing a membrane stack comprising the steps of (i) interposing a curable adhesive between alternate anion exchange membranes and cation exchange; and (ii) curing the adhesive; CHARACTERIZED IN THAT said membranes are in a swollen state when step (ii) is performed.

A radar sensor for emitting and/or receiving wave-shaped electromagnetic signals, having at least one housing and at least one absorber. The absorber is disposed inside the housing and a surface of the absorber has raised rib-like sections which are disposed adjacently to one another on the surface of the absorber. The absorber is an injection molded component.

A fastener joinable to a workpiece, the fastener comprising: a shaft-shaped anchor section that extends along an anchor axis (Xa) between a first end portion and a second end portion; a flange section formed on and extending radially from the first end portion of the anchor section; and an application section located on the flange section. A pre-applied joining material is located on the application section and is at least partially in a solid state. The joining material includes a first adhesive material and a second different adhesive material, and the first adhesive material completely covers the second adhesive material.

A fastening element for attaching to a wall. The fastening element having a contact element having an adhesive surface and a filling opening via which a flowable adhesive agent is capable of being brought between the adhesive surface and the wall. Positioning elements by which the contact element is capable of being positioned at the wall are arranged at the adhesive surface. The positioning element has a width which is variable in dependence on a spacing from the outlet opening. The width reduces at least sectionally as the spacing from the outlet opening increases and is minimal at a maximum spacing from the outlet opening. Accordingly, the adhesive surface is capable of flowing around the positioning element on the introduction between the wall and the adhesive surface.

Apparatuses, systems, and methods associated with placement of magnets within a microelectromechanical system device are disclosed herein. In embodiments, a method of affixing at least one magnet in a microelectromechanical system, may include affixing an electromagnetic actuator to a base structure of the microelectromechanical system, the affixing including affixing the electromagnetic actuator within a recess formed in the base structure. The method may further include placing a magnet within the recess, wherein the recess includes at least a portion of a spring, the spring affixed to the base structure and extending into the recess, the placing including placing the magnet on a side of the electromagnetic actuator, between the spring and the side of the electromagnetic actuator, the spring pressing the magnet against the side of the electromagnetic actuator and maintaining a position of the magnet in response to the placing the magnet within the recess.

A deflection member that includes a reinforcing member and a plurality of tiles fastened to the reinforcing member.

A deflection member that includes a reinforcing member that includes a resin coating, and at least one tile fastened to the resin coating.

A method of adhesively bonding a first substrate on a second substrate in an adhesive bonding zone by an adhesive joint integrating a support mesh, wherein surplus adhesive joint is folded over onto one or the other of the first or second substrates so that the support mesh is present over the entire adhesively bonded zone after curing.

Printable magnetic receptive composite sheets are made by calendering a thin layer of a magnetic composition and bonding it to a top printable layer on one or both sides of the magnetic layer wherein the calendered layer has a thickness up to 10 mils.
