  • Publication number: 20200064281
    Abstract: A system (100) for producing analysis data indicative of presence of one or more predetermined components in a sample (110) is presented. The system includes source equipment (120) for directing a particle stream (130) towards the sample (110), detector equipment (140) for measuring a distribution of particles scattered from the sample (110) as a function of a scattering angle (?), and processing equipment (170) for producing the analysis data based on the measured distribution of the scattered particles and on reference information indicative of an effect of the one or more predetermined components on the distribution of the scattered particles. The scattering angle related to each scattered particle is an angle between an arrival direction of the particle stream and a trajectory (160) of the scattered particle. The system utilizes different directional properties of scattering related to different isotopes, different chemical substances, and different isomers.

  • Patent number: 9862565
    Abstract: The present invention concerns a method for removal of material residues, particularly tissue or similar porous, non-self-supporting materials, from a material-carrying core, which often has relatively large dimensions, e.g. a diameter of approx. 300 mm and a length of approx. 2540 mm, and thereby allow re-use of the core in the same way as new and unused cores a number of times for winding non-self-supporting or porous material, particularly tissue, wherein a cut section is made in the envelope surface of the roll having the material-carrying core from one end or end portion of the roll to the other end or end portion of the roll by means of a driven rotary knife, which is connected to a motor for rotation of the same.

  • Patent number: 9334883
    Abstract: A method is provided for controlling a hydraulic system of a working machine. The hydraulic system includes a hydraulic machine for providing hydraulic fluid to one or more actuators of the working machine. The method includes receiving a signal requesting a pump pressure from the hydraulic machine based on the load pressure of a first actuator of the one or more actuators which first actuator has the highest load pressure of the one or more actuators, discriminating the pressure request from the first actuator provided that the first actuator is stalled due to overload or geometrical limitations, and controlling the hydraulic machine to provide a pump pressure based on the load pressure of a second actuator of the one or more actuators which second actuator is in operation and has the second highest load pressure of the one or more actuators, or, if no actuator in addition to the first actuator is present and in operation, controlling the hydraulic machine to provide a predetermined idle pump pressure.

  • Patent number: 9318294
    Abstract: The invention relates to a switching device for short-circuiting and earthing at least two phases in an electric power network. The device comprises a first phase contact, a second phase contact, and an earthed, movable contact, which can, on the one hand, assume a first position, where the contact is insulated from the phases, and, on the other hand, a second position, where the contact is connected to the phase contacts and thereby earths and short-circuits the phases.

  • Publication number: 20160094028
    Abstract: An arrangement for voltage conversion for a boat, for example a leisure boat, includes a DC voltage converter that converts a first DC voltage provided by a low voltage source, for example a battery, to a second DC voltage of at least 24 V for supplying at least one consumer with power. The arrangement also includes an interconnector for interconnecting the voltage converter and the at least one consumer, and a controller that is adapted to transfer the voltage converter between an idle mode, in which substantially no power is supplied to the at least one consumer, and an active mode, in which power is supplied.
