Publication number: 20250129831Abstract: A spring carrier for receiving, retaining, and discharging of a coil spring in a manufacturing assembly process includes an elongate hollow body defining an inner cavity to receive the coil spring and an opening at a proximal first end of the hollow body for the insertion of the coil spring into the inner cavity and extraction of the coil spring from the inner cavity. A deflectable member is located proximate to the first proximal end and includes a retaining portion that retains the coil spring when the coil spring is located within the inner cavity. The deflectable member is movable between a first unbiased position, where the retaining portion extends into the inner cavity to retain the coil spring within the inner cavity, and a second biased position, where the retaining portion is disposed outwardly to allow the coil spring to be extracted from the inner cavity through the opening.Type: ApplicationFiled: June 23, 2022Publication date: April 24, 2025Inventors: Philippe Chabert, David Darras

Publication number: 20250035261Abstract: A device for lubricating a surface of a tubular element includes a shaft portion having a longitudinal axis, and a brush portion located on the shaft portion. The brush portion comprises at least one radial projection having a helical form. The protrusion comprises at least one contact zone for contacting a surface. An outer diameter of the helical form formed by the at least one contact zone is tapered at both longitudinal ends of the brush portion such that the outer diameter of the helical form is reduced at the longitudinal ends of the brush portion. The brush portion is formed from a brush portion material and a lubricant agent which is transferred from the at least one contact zone to a surface during use.Type: ApplicationFiled: November 30, 2022Publication date: January 30, 2025Inventors: Philippe Chabert, David Darras
