Publication number: 20230294386Abstract: The invention relates to the use of special polymer layers as barriers, in particular as barrier layers in composite materials. Suitable polymers for the polymer layer are copolymers consisting of ethylene and vinyl alcohol or consisting of ethylene and carbon monoxide or consisting of ethylene and carbon monoxide and propylene. These barrier layers exhibit a selective barrier effect with respect to different gases, the barrier effect being especially effective with respect to HFOs. On account of these properties, such barrier layers can positively affect insulating properties, for example in thermally insulated pipes.Type: ApplicationFiled: August 22, 2022Publication date: September 21, 2023Inventors: Jürgen Kress, Christian Dambowy

Publication number: 20220125283Abstract: An endoscope for the minimal invasive examination or surgical treatment of a patient has a flexible tubular shaft for insertion into the patient, a grip attached to a proximal end of the shaft for holding the endoscope, and at least one hollow tube. The shaft has at least one groove extending axially along an outer face of the shaft and in which the tube is removably housed. The tube has at least one working channel for guiding a surgical instrument, and/or carrying water or air to or providing suction at the shaft distal end. The shaft groove and the tube are dimensioned relative one another such that at least one free section of the tube is afforded play in the groove. In the straight extended state of the shaft, the at least one free section has an exterior cross-section which is slightly smaller than an interior cross-section of the groove.Type: ApplicationFiled: March 11, 2020Publication date: April 28, 2022Applicant: ES ENDOMED SOLUTIONS GMBHInventor: Jürgen Kress

Patent number: 10471635Abstract: For manufacturing composite parts (1) having an inner hollow moulded body (2) with openings (3), which are accessible from outside, the moulded body is introduced into a moulding tool on the mould walls on which a shell layer (11) was applied. The hollow space between the moulded body (2) and the shell layer (11) is filled with a thermally insulating plastic foam (12) which is foamed in the moulding tool and bonds to the moulded body and the shell layer. After removal, a moulded body is provided, which has a qualitatively good surface formed by the shell layer. Such a composite part is preferably used for connecting thermally insulating pipes.Type: GrantFiled: August 5, 2015Date of Patent: November 12, 2019Assignee: Brugg Rohr AG HoldingInventors: Alfred Oeschger, Juergen Kress, Christian Dambowy
