The invention relates to a device for separating particles from a particle containing liquid and comprising a separating chamber having a bottom (6) and side walls (2, 4, 5, 7), an inlet (10) for liquid with particles, an outlet (18) for the liquid essentially freed of particles, an outlet (11) for the discharge of particles, wherein at least one separating element (15), on which particles in the liquid may settle, is arranged between the inlet (10) and the outlet (18) for liquid, said liquid flowing essentially in a vertical direction between inlet and outlet, wherein the liquid outlet (18) communicates with an additional chamber (9) likewise comprising a bottom (6) and side walls (2, 3, 4, 7), wherein one side wall is formed with a liquid outlet (12) whose upper edge is provided below the level of the lower edge of the particle outlet (11). The invention moreover relates to a method, in connection with a device for separating particles from a particle containing liquid wherein the particules settle on separating elements in the device, of cleaning said device and in particular its separating elements in that a gas under pressure is supplied to the liquid in the device at a level below the lower edge of the separating elements.

A device for forming bows from a ribbon which includes a base plate (22) and a pair of uprights (24, 26) mounted on the base plate. One of the uprights is resiliently biased toward the other upright for grippingly engaging portions of the ribbon inserted therebetween to hold bow loops formed from the ribbon in place while forming the bow. A tie wire (80) is placed between the uprights for securing the portions of the bow loops retained between the uprights before removing the assembled bow loops. The uprights have opposed narrow edges to effectively grip the ribbon positioned therebetween. In one embodiment of the invention, the uprights include spaced upright plates (28) to receive the tie wire and a forming arm (70) which moves the portion of the bow loops between the uprights toward the base plate (22).

The invention relates to a method for the drying and combustion of water-containing material containing combustible components, such as dehydrated waste water sludge, and wherein a water-containing material is introduced into a direct dryer, drying of the material introduced into the dryer by introduction of atmospheric air as drying air into the dryer, introduction of the dried material into a furnace and combustion of the material therein, introduction into the furnace of at least a portion of the drying air after the dryer as combustion air, preheating of the drying air intended for the drying of the material by utilization of the heat contained in the hot flue gas discharged from the furnace, while water is supplied to the atmospheric air in connection with the preheating whereby the water is evaporated, and wherein the water content in the drying air is reduced after the dryer in a condenser prior to its introduction as combustion air into the furnace. Moreover, the invention relates to a plant for carrying out this method. In such method it is possible to dry e.g. waste water sludge with a high water content to a degree of dryness that allows burning without auxiliary fuelling. Hereby improved operational economy is obtained.

A demodulator (16) for use in a receiver for transmission systems is adapted to demodulate received signals according to a coherent principle in a first mode and to demodulate received signals according to a non-coherent principle in a second mode. The demodulator comprises a differential detector (18), an equalizer (21) and a switch (19) adapted to couple the received signals directly to the equalizer (21) in the first mode of the demodulator and to couple the received signals to the equalizer (21) via the differential detector (18) in the second mode of the demodulator.

The present invention concerns a containership (20) having transverse lashing bridges (1) comprising lashing eyes (7) from which lashing rods (9) extend upwards to secure containers (8) at an upper level. The lashing bridges (1) have at least one substantially horizontal walkway (4) for handling of said lashing rods (9). Further, the walking level of the walkway (4) is arranged at a lower level than the lashing eyes (7, 17) to allow a person to carry out the lashing procedure standing in a substantially upright position.

A traffic control system for mobile units comprises a plurality of stationary, passive units having electronic store capacity and transmit and receive facilities. The store of the passive units contains an information code which is unique to the unit and is related to the position of the unit concerned. A mobile unit has a computer with associated store capacity and transmit and receive facilities. When interrogated by a mobile unit, the stationary units supply their information code, enabling the mobile unit to calculate its position. The store of the stationary units, in addition to the information codes of said units, contains stored traffic messages which are supplied together with the information code upon interrogation from the mobile unit. The movement from the mobile unit can be adjusted according to the traffic information received.

A spray drying system having a whirl chamber nozzle (1) with a bypass (22, 23, 10, 7) and for atomization of a liquid. The whirl chamber (2) of the nozzle (1) has a central discharge orifice (19), from which a ring-shaped bypass passage (22) extends radially outwards. This ensures that substantially no air enters the bypass from the whirl chamber (2), while providing acceptably low flow growth values.

A low product level detector is disclosed which utilizes a sensor comprised of an infrared emitter (103) and receiver (104) to project a beam of light (105) across a cavity/enclosure which contains a solid product (65). When the product reaches a level at which more solid product should be added, an alarm indicia means is triggered. The alarm indicia means is comprised of an audible horn (106) and a visually perceptible light (107). The low product alarm is utilized in a dispenser (10) for dispensing a wash chemical solution which has been created by dissolving a solid wash chemical in a diluent. By maintaining a predetermined amount of solid wash chemical in the dispenser, the wash chemical solution maintains a more constant concentration.

A conveyor with an endless flexible cone-shaped belt which extends over at least two conical rollers between which the belt is kept stretched in a controlled curve path, said belt being provided at its longest edge with a plurality of control elements which stretch the belt under the engagement of the control elements with a first travelling path, which is retained with respect to a frame and extends along the longest edge of the belt in the vicinity of the opposite inner sides of the transport path and the return path of the belt, and in which a second travelling path for the simultaneous engagement of the control elements extends substantially in parallel with and at a distance from the first-mentioned travelling path in the vicinity of the outer sides of the belt facing away from each other, said second travelling path being retained with respect to the frame by means of a plurality of yokes in order to provide free passage for the control elements. This also ensures easy cleaning and service of the control elements as well as a significant reduction in wear and noise over the prior art.
