Patent number: 10640252Abstract: The invention relates to a method of operating an apparatus for applying drinking straws to packaging containers. The method comprises the step of moving a drinking straw carrier from an application position to the leaving position, in a packaging container moving direction, maintaining a velocity in that direction being equal to a constant velocity of a first conveyor. The invention also relates to an apparatus being operated according to the method.Type: GrantFiled: November 27, 2015Date of Patent: May 5, 2020Assignee: TETRA LAVAL HOLDING & FINANCE S.A.Inventors: Ashraf Zarur, Björn Karlsson

Patent number: 9676512Abstract: A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device comprises two opposing sealing elements between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first transverse seal of the tube. It further comprises two volume control elements. The forming device is characterized in that it is arranged to displace the first transverse seal off-center in relation a longitudinal axis of the first portion of the tube in a displacement direction essentially perpendicular to the first transverse seal to enable later shaping of a corresponding final package with a wall arranged with a predetermined angle of inclination in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.Type: GrantFiled: November 12, 2013Date of Patent: June 13, 2017Assignee: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventors: Björn Karlsson, Niels Damkjaer, Tomas Lagus

Patent number: 9071888Abstract: A telemetry system for use in a combustion turbine engine (10) having a compressor (12), a combustor and a turbine (16) that includes a sensor (306) in connection with a turbine blade (301) or vane (22). A telemetry transmitter circuit (312) may be affixed to the turbine blade with an electrical connecting material (307) for routing electronic data signals from the sensor (306) to the telemetry transmitter circuit, the electronic data signals indicative of a condition of the turbine blade. A resonant energy transfer system for powering the telemetry transmitter circuit may include a rotating data antenna (314) affixed to the turbine blade or on a same substrate as that of the circuit. A stationary data antenna (320) may be affixed to a stationary component such as a stator (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna.Type: GrantFiled: January 28, 2011Date of Patent: June 30, 2015Assignees: Siemens Aktiengesellschaft, ARKANSAS POWER ELECTRONICS INTERNATIONAL, INCInventors: Ramesh Subramanian, Anand A. Kulkarni, David J. Mitchell, Bjoern Karlsson, Rod Waits, John R. Fraley

A stationary data antenna (333) may be affixed to a stationary component (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna. A second sensor (335) transmits electronic data signals indicative of the stationary component to a second telemetry circuit (332), which routes the signals to the stationary antenna. The stationary antenna transmits the electronic data signals to a receiver (338).Type: GrantFiled: January 28, 2011Date of Patent: August 5, 2014Assignee: Siemens AktiengesellschaftInventors: Ramesh Subramanian, Anand A.

Patent number: 6325889Abstract: A new and improved way of continuously cooking fiber material, wherein temperatures and alkaline levels are controlled to be maintained within specific levels in different zones of the digesting process in order to optimize chemical consumption and heat-economy and at the same time achieve very good pulp properties. The digesting process includes a top separator that separates the transport liquid from the fiber material and permits the fiber material to be exposed to the cooking liquid.Type: GrantFiled: December 14, 2000Date of Patent: December 4, 2001Assignee: Kvaerner Pulping ABInventors: Vidar Snekkenes, Johan Engström, Sven-Erik Ohlsson, Per Nyström, Sören Söderqvist, Björn Karlsson
