The method includes the step of passing an electric current through at least one wire that is situated between a carcass of a tire casing and a tread. The method also includes the step of calculating a value of a temperature of the wire as a function of a relative value of the current. The method proceeds with the step of controlling the current as a function of the temperature value calculated.

An exoskeleton system comprising an inflatable actuator configured to be worn by a user. The inflatable actuator includes a fluid-impermeable member that defines a fluid chamber at least in part by a membrane material and a first and second interface that each define sidewalls, the membrane material is coupled to the sidewalls of the first and second interfaces.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

An attachment part (10) for connecting to a structural part (30). The attachment part (10) has an attachment part longitudinal axis (A), and a weld portion (11) to be welded to the structural part (30) by torsional ultrasonic welding. The weld portion (11) has a contact surface for contact with a torsion sonotrode (70), and a weld surface (13) for connecting to the structural part (30). The weld portion (11) is delimited, at least portionally, by an inner vibration decoupling zone (14). The inner vibration decoupling zone (14), at least portionally, surrounds an inner portion of the attachment part (10).

An add-on part (10) for connecting to a component (30). The add-on part (10) has a longitudinal axis (A) and a welding section (11) to be welded to the component (30) by torsional ultrasonic welding. The welding section (11) has a contact surface (12) for contact with a torsion sonotrode (70) and a welding surface (13) for connecting to the component (30). The welding section (11) is delimited, at least in some sections, by an inner vibration-decoupling zone (14). The inner vibration-decoupling zone (14) extends, at least in some sections, at an inclination to or parallel to the longitudinal axis (A). The method comprises a) bringing the welding surface (13) in contact with a welding region (31), b) applying a force to the contact surface (12) such that the welding surface (13) is pressed against the welding region (31), and c) introducing a torsional ultrasonic vibration into the welding section.

A sealing structure for a front cover of an engine includes a front cover made of resin of an engine in which a through-hole, into which a boss part of a torsional damper is to be inserted, is provided, and a sealing apparatus to seal between the through-hole of the front cover and the shaft part. The sealing apparatus includes a support ring that is made of resin and has an annular shape, and an elastic body part that is made of an elastic material, has an annular shape and is attached to the support ring. The elastic body part has an annular seal lip that contacts the shaft part such that the shaft part is able to slide, and the support ring is bonded to the front cover.

The invention relates to a method for the ultrasonic welding of two plastic components using a sonotrode, wherein the energy for the welding is introduced into the plastic components via at least one or more pins of the sonotrode, wherein the two plastic components are welded to one another step by step, wherein the respectively subsequent step of the welding is carried out in a region which has already been loaded and relieved of tension as a result of the preceding step of the welding.

The present disclosure relates to a pre-treatment composition for sealing polymeric film, said composition comprising: 0.5 to 10 weight % of a halogenated carboxylic acid, a surfactant, and a liquid solvent.

A sterile container including at least one hollow fiber filter module, especially dialyzer, which is accommodated in a hermetically sealed holding volume of a primary package and includes a blood compartment delimited by a blood inlet opening and a blood outlet opening, wherein a plurality of hollow fiber filter modules is arranged in the primary package and the sterile barrier of the blood compartment of each hollow fiber filter module inside the primary package is implemented by caps which close the blood inlet opening and the blood outlet opening of each hollow fiber filter module. A method of manufacturing such sterile container is also disclosed.

A tank (e.g., an underground storage tank), and manufacturing methods therefore, may include a tank body having an exterior surface. A component is mounted on at least a non-planar portion of the exterior surface of the tank body using an adhesive (e.g., an MMA adhesive). For example, the component may be positioned on the non-planar portion of the exterior surface of the tank body after application of adhesive and pressure may be applied to maintain the position of the component on the non-planar portion of the exterior surface of the tank body as the adhesive is cured. The pressure may be removed upon curing of the adhesive and formation of a structural bond may occur at the adhesive interface between the mounting surface of the component and the non-planar portion of the exterior surface of the tank body.
