The present invention concerns a method and a device for sealing packages (1) during continuous movement. A row of packages (1) is driven by means of a motor (8) through a sealing station comprising an inductor (4). The inductor (4) is driven in a pulse form by means of an IH (induction heating) inductor (5). A PLC system (6) is used to control the IH generator (5). The PLC system (6) receives inf...

A curling slider which may be a shoe or an attachment for a shoe includes a flexible sole located under the foot of the curler attached to which is a slider plate having a slider bottom surface designed to slide across the ice . In front of the slider plate is a toe portion and behind is a heel portion each of which is formed of slider material. The slider plate is circular in plan and is received...

A method and an arrangement are disclosed for implementing fast signalling in a communication connection between a base station and a mobile station of a cellular radio network. There is defined an arrangement of repeatedly occurring frames that consist of pieces of allocatable radio communication capacity between the base station and mobile stations communicating therewith. Pieces of radio commun...

The present invention relates to stabilisation of proteins. A theoretical basis for new protein engineering strategies is presented, based on defining rules for strong hydrogen bonds in proteins. In the present invention pairs of carboxylic acid side chains are used to stabilise proteins, or to form pH-dependent molecular switches.

The floor unit (10), generally rectangular in shape, has a glued multi-layer top panel (11) comprising two longitudinally grained sheets (14,16) with a cross grained middle sheet (15). The glued supporting joists (17) may be lightened with cut-outs (17). Bottom flanges are formed with added battens (18) leaving recesses (12) under the joists. The cavities (13) may be filled with an insulating mate...

The method involves holding a braking force on at least on wheel of the vehicle independently of the brake pedal position when the vehicle stationary state is detected and relieving the force if at least one condition for doing so exists. The braking force is reduced irrespective of the condition if sliding of the vehicle is detected. At least one condition for reducing the force is expiry of a pe...

A detector (9) for detection of ionizing radiation comprises a cathode (17, 41); an anode (19); an ionizable gas arranged between these electrodes; a radiation entrance (33) arranged such that ionizing radiation (1) can enter and ionize the ionizable gas; and a read-out arrangement. A voltage across the electrodes causes electrons created during ionization of the gas to drift towards the anode, wh...

The hub has a universal design enabling it to be used adapted for all types of wheels.

Method and arrangment in the automatic landing of an aircraft (1), comprising a unit (4) arranged on the aircraft (1) and designed to form an image of a group of radiation sources (3) located next to a runway (2), and a calculation device connected to the imaging unit (4) and designed to continuously calculate the position and orientation of the aircraft (1) in relation to the runway (2) using the...
