A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool.

Flange connection for connecting two pipeline ends made of plastics material and method for assembly, containing two mutually opposing pipe ends (2) made of plastics material, wherein the pipe ends each have a prewelding neck, two loose type flanges, wherein a loose type flange is arranged at each pipe end, wherein the loose type flanges have holes for mutual clamping, clamping means, wherein the clamping means are arranged in the holes and serve to mutually pull together the loose type flanges and the pipeline ends, and a sealing element, wherein the sealing element comprises a conductive plastics material and exclusively one material.

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

Disclosed are grips and methods of making grips for use with the handle of an article, and in particular for use with fishing poles and golf clubs. Grips preferably include a multi-layered gripping member and an inner sleeve or mounting body. The gripping member can include an outer layer with a fabric layer coated and preferably saturated by polyurethane. The outer layer can be bonded to an inner layer to form the gripping member which is then attached to the sleeve. The sleeve can be ground from a starting block of material or may be injection molded. Also disclosed are handles including a connector configured to couple to a portion of a fishing pole. Such handles may include a multiple layers and can be selectively removed from the article. Methods are also provided for selectively coupling exchangeable handles to articles including fishing poles.
