Publication number: 20240085378Abstract: A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc.Type: ApplicationFiled: November 15, 2023Publication date: March 14, 2024Applicant: Kamstrup A/SInventors: Søren Tønnes Nielsen, Peter Schmidt Laursen, Jens Lykke Sørensen, René Gajda Kristensen, Martin Christian Høj Petersen

Publication number: 20230235966Abstract: A fluid coil includes a tube bundle having a series of straight tubing runs and a series of return bends extending between and fluidically connecting ones of the straight tubing runs, an expansion header fluidically connected to at least some of the return bends and a polymeric material disposed in the expansion header. The polymeric material has an initial shape and is compressible to repeatedly expand and contract between a first volume in which water is present in the tube bundle and a second volume in which the water undergoes a phase change. Contraction of the polymeric material absorbs an increase in volume as the water undergoes the phase change to prevent stressing and rupture of the tube bundle and upon an opposite phase change, the polymeric material returns to its initial shape. The polymeric material can be a pressurizable bladder. A system and method to prevent the rupture of a tube bundle in a fluid coil are also disclosed.Type: ApplicationFiled: March 28, 2023Publication date: July 27, 2023Inventors: Long Phan, Christian Sorensen

Patent number: 10864297Abstract: A method of manufacturing an implant for use in a surgical procedure, a corresponding implant and the use thereof during the incorporation of a substance is presented. Specifically anodized and blasted titanium implant substrates are provided with a hydroxyapatite (HA) coating for incorporating for example a therapeutic agent. In particular, an anodizing procedure by an electrolytic process in an alkaline liquid is carried out. Moreover, blasting of the anodized titanium implant substrate is carried out by the presented method. The HA coating can be in the range of 1 to 5 ?m, particularly in the range of 1 to 3 ?m. A local delivery of the active pharmaceutical ingredient is achieved by the implant of the present invention. Moreover, the implant allows for the removal of the implant without damaging surrounding tissue or a bone. Moreover, the HA coating is provided to the substrate such that enhanced fixation as measured by pull-out force is achieved whilst having a relatively low removal torque.Type: GrantFiled: September 2, 2013Date of Patent: December 15, 2020Inventors: Philip Procter, Jan Henrik Sörensen, Hartwig Steckel, Torben Christian Sörensen, Ken Welch
