Abstract: Disclosed herein is a method of tensioning a web packaging material in a form-fill-seal packaging apparatus wherein the web is pulled from a supply roll through web feeding rolls, guided over means for forming it into tubing and fed toward means for feeding the tubing forward, and wherein articles to be packaged are provided in the tubing and sealing operations are performed on the tubing to seal it to form packages. The invention method is characterized in that the web feeding rolls and the tubing feeding means are concurrently started, and when the web feeding rolls and the tubing feeding means are stopped to form a seal on the tubing, the tubing feeding means is stopped slightly later than the web feeding rolls so that the web forward by the web feeding rolls is taken up and pulled toward the tubing feeding means under tension. Another method is disclosed for tensioning a web between the supply roll and the web feeding rolls, wherein a suitable braking is applied to the rotating supply roll so that the web fed forward by the feeding rolls is taken up under tension.

Abstract: The present invention relates to an apparatus in ringing signalling to a called subscriber. Connection and disconnection of the signal takes place with the aid of the apparatus. The problem solved by the invention is that of current transients being generated on disconnection of the signal, these transients causing a disturbing clicking noise in the engaged telephone of a subscriber in a neighbouring channel. The apparatus solving the problem includes a two-way switching circuit (10) connected in series with an AC voltage generator (2), said circuit disconnecting the AC voltage to a bell (1) when the current through the bell has its zero crossing, and a discharge circuit (11) for discharging the bell before it is connected via a relay (3) to a SLIC circuit (4), such that the voltage across the bell is within the SLIC circuit voltage interval when the relay (3) connects the bell to the SLIC circuit (4), which occurs when said signal is disconnected. By this arrangement an overvoltage protector (7) connected to the SLIC circuit (4) is not triggered, and the circuit is not subjected to any current transient which can cause disturbing clicking noises.

Abstract: The invention involves a method for measuring the temperature in a heating system of the type having an electrically heated hot plate with a filled cooking vessel on it and a radiation pick-up located at varying distances from the side of the vessel and pointed at it which emits a signal indicating the temperature of the substance in the vessel based upon radiation from an area on the side of the vessel as detected by the radiation measurement field of the radiation pick-up, the radiation intensity of which decreases as a square of increasing distance. To compensate for the effect on measurements of spurious radiation form the changing position of the vessel on the hot plate, the invention involves adjusting the angle of a non-intersecting radiation measurement field to obtain corresponding reduction in the area of radiation detetion on the vesel for increasing distances between vessel and radiation pick-up.

Abstract: The invention relates to a method and a controlling apparatus for controlling the magnitude and direction of a current (I) through a winding (L). The method and controlling appartus are based on a drive circuit (TR1, D1, TR2, D2, TR3, D3, TR4, D4) which is controllable such as to enter into three different types of operational state. In a first type of operational state the current is normally increasing in magnitude. In a second type of operational state the current is normally decreasing in magnitude comparatively slowly. In a third type of operational state the current magnitude is normally decreased comparatively rapidly. When the drive circuit is in the first type of operational state it is controlled either to remain in this state or to change to the second type of operational state in response to the result of at least one comparison between the actual value of the current and a desired value (I*) carried out during the time the drive circuit was in the first type of operational state. When the drive circuit is in the third type of operational state it is controlled either to remain in this state or to change to the second type of operational state in response to the result of at least one comparison between the current actual value and a desired value carried out during the time the drive circuit was in the third type of operational state. The method and apparatus are primarily intended for microstepping a two-phase stepping motor with a permanent magnetized rotor.

Abstract: An arrangement in a water craft is described for collecting oil present on the surface of water, especially among blocks of ice. The arrangement comprises a bow part (2) the flat lower surface (3) of which is gently sloping and equipped with inlet openings for contaminated water. When the craft is moving forwards, blocks of ice are pressed under the surface (3) and at the same time rinsed. The rinsing can be promoted by means of strong water jets. In order to achieve the optimal operating conditions in each particular case, the bow part (2) has been arranged to be a part separate from the hull (1) of the craft and capable of being raised and lowered in relation to the hull, which also enables this bow part to be coupled to an already existing craft of suitable size. The bow part comprises separating devices (9) for separating oil from the inflowing water, as well as a device for removing the cleaned water. The recovered oil is conveyed continuously from the bow part (2) to a tank located, for example, in the craft.

Abstract: In refrigerating systems and heat pump systems, thermostatic expansion valves are used to deliver a precisely correct quantity of refrigerant to an evaporator under changing operational conditions. The valve shall maintain equilibrium between delivery of the refrigerant and the removal by suction of said refrigerant under all operating conditions. In order to prevent the expansion valve of a refrigerating or heat pump system from remaining closed due to low bulb temperature, where several refrigerating batteries/evaporators with expansion valves are arranged in parallel and where a substantially constant suction pressure prevails and closing of the valve will not therefore influence the system suction pressure, there has been arranged over the expansion valve, between the high pressure side and the low pressure side, a connection (5, 6, 8) which has an adjustable or fixed through-flow area and which will guarantee that a minimum amount of refrigerant is vapourized in the evaporator such as to produce superheated gas for heating a bulb connected to the expansion valve.
