Abstract: A disc filter includes a filtrate holding tank disposed below a series of disc-shaped filter members supported on a drum. Filtrate from the holding tank is used to backwash filter media on the disc-shaped filter members. Filtrate is discharged from the holding tank via a filtrate conduit. Bypass water is directed through a bypass conduit in the disc filter and mixed with the filtrate downstream of the filtrate holding tank. This assures that the filtrate used to backwash the filter media does not include bypass water.

Abstract: A method of assembling a structure of timber lengths, e.g. roof trusses, includes a number of upper and lower structure lengths or pieces, as well as a number of diagonals or braces etc., in which the timber lengths are laid out and fixed to one another. The structure formed from the timber lengths fixed to one another is observed by a first camera for positional determination of the structure and comparison of observation data with structure data and for controlling at least a second camera. The structure is fed into a unit for pressing in place of jointing pieces, e.g. corrugated fasteners, over the joints between the timber lengths by at least one positionable press unit, and the second camera observes the infed structure and positions the press unit at the correct position over a joint for pressing in place of a jointing piece.

Abstract: A gyratory crusher comprises a first crushing shell mounted on a crushing head, and a second crushing shell mounted on a machine frame, a crushing gap being formed between said first and second crushing shells. A method of controlling the operation of said crusher comprises measuring a parameter being representative of the stresses to which the crusher is exposed during the crushing of material, determining an average value of said parameter, determining a deviation value of said parameter, calculating a peak value based on said average value and said deviation value, comparing said peak value to a reference value, and controlling the operation of the crusher in view of said comparison between said peak value and said reference value.

Abstract: A gyratory crusher has a crushing head on which a first crushing shell is mounted, a frame on which a second crushing shell is mounted, and a driving device, which is arranged with a rotating eccentric to cause the crushing head to execute a gyratory movement for crushing of material. The crushing head is connected to the frame of a rotation-restricting arrangement, which comprises a beater in a tank. Spinning of the crushing head is restricted by the beater being braked, during operation of the crusher, by a liquid contained in the tank.

The internal components are submerged in transformer oil and are provided with insulation for insulating a high voltage winding end. The insulation includes a shield ring arranged above the winding end and a pressboard structure formed in a zigzag pattern arranged around the winding end. The shield ring includes a core covered with a conducting layer and a continuous solid insulation layer outside the conducting layer. The insulation layer includes integrated solid insulation sections of which at least some among themselves having varying thickness. Also a shield ring and a method of manufacture the shield ring.

Abstract: A high voltage insulation system for high-voltage direct current including a bushing, a conductor, a transformer conductor, and a connection between the conductor and the transformer conductor. A conductive shielding electrode shields the connection between the bushing and transformer. A surrounding insulation system is immersed in transformer oil. The surrounding insulation system includes transformer insulation material and bushing insulation material. A cylindrical solid insulation barrier encloses the connection between the bushing conductor and transformer conductor. At least one solid insulation barrier is fastened on the outer side of the shielding electrode. The at least one solid insulation barrier extends in an axial direction outside the axial direction of the shielding electrode and forms a distance to the insulation material of the bushing and the insulation material of the transformer, whereby a moderate voltage drop over the solid insulation barrier is obtained.

Abstract: A counter blade is disclosed for use in a chipping machine which comprises a chipper disc rotatably mounted in the chipper frame by means of a shaft supporting the disc. The counter blade is attached to the chipper frame essentially at the intersection of a blade mounted in the chipper disc and the log to be chipped, in such manner that, on the side opposite to the chipping blade, the counter blade rests against the log to be chipped. The counter blade consists of a first and a second blade part placed at an obtuse angle relative to each other. According to the present invention, the counter blade consists of two essentially elongated elements having an arris forming the cutting edge of the counter blade at least on one of its longitudinal sides. The end faces of the counter blade elements are so formed as to permit connection to an adjacent counter blade element so that two counter blades form a continuous cutting edge of the counter blade.

Abstract: The lifting device comprises a frame to which coupling members are provided to co-operate with attachment members located in the corners of the container. Each coupling member is capable of cooperating with an attachment member so that at a first reciprocal movement of the coupling member, coupling between the coupling member and the attachment member takes place, and so that at a further reciprocal movement of the coupling member the coupling member and the attachment member are uncoupled. The reciprocal movement is caused by the bottom end of the coupling member striking the bottom interior surface of the attachment member.
