Abstract: In a method for precise alignment of impressions made by different inks, a rotary printing surface is used for printing a material. The different inks to be aligned with respect to each other are printed on different areas of the material by the same rotary printing surface, such as an impression roller.

Abstract: A method of controlling the production of filler-containing paper. Filler and retention agent are delivered to a paper manufacturing system in a process of paper manufacture. The amount of filler in the paper is measured, as is also the filler concentration or the total concentration in the white water or the stock. Filler is delivered such that the system will be buffered with filler to a generally pre-determined concentration level. The continual addition of retention agent is based exclusively on the amount of filler in the paper measured at that moment in time. When the measured amount of filler present is lower than a desired level, the addition is increased. When the measured amount of filler present is higher than a desired level, the addition is reduced. The continual addition of filler is based, exclusively on the concentration level of filler measured in the white water or the stock.

Abstract: The invention relates to a method of controlling the production of filler-containing paper. Filler and retention agent are both delivered to the paper manufacturing system in such a process of paper manufacture. The amount of filler in the paper is also measured, as is also the filler concentration or the total concentration in the white water or the stock. Filler is delivered in a quantity such that the system will be buffered with filler to a generally pre-determined concentration level (control value), which is followed via measuring processes.

Abstract: An apparatus for ejecting fasteners from a magazine by an impact member. The magazine includes an adjustment device for selective adaptation of the magazine to fasteners of a plurality of predetermined lengths. The adjustment device has a body which is rotatable about a longitudinal axis and fixable in at least two positions. The body has two or more longitudinally extending slots, each of different depth, for accommodating a portion of the fasteners. The slots are arranged in the cylindrical body such that when each slot si aligned with a row of fasteners, the longitudinal axis of the cylindrical body is offset from the row of fasteners in a manner such that the longitudinal axis of the cylindrical body does not lie directly above the row of fasteners.

Abstract: Apparatus operating by means of compressed air, comprising a displaceable cylinder, open at both ends, in which there bears a displaceable piston designed for expulsion of fixing elements fed forward below the piston. The cylinder and the piston are displaceable, by the action of air, in a cylinder housing between an upper and a lower end position at which are arranged damping elements. The cylinder and the piston bear with their respective and faces at their respective end positions against a surface of the damping element. The apparatus comprises an inlet and an outlet for the air, the flow of which is controlled by means of a valve, and an upper chamber and a lower chamber. These chambers are in connection with the inside of the cylinder by means of at least one opening in the cylinder wall. Furthermore, the apparatus comprises at least one second opening in the cylinder wall which is in connection with the outlet via a return channel depending on the position of the cylinder.

Abstract: A supply device for use in an evaporative contact body of the multi-layer type having gaps between the layers of the body to which water is supplied from above comprises water supply pipes having outlet openings formed therein. The pipes are in direct contact with the top of the contact body or may be embedded therein, and the pipe openings are located to direct water jets directly inside the gaps between the layers of the contact body.

Abstract: Power transmission apparatus for controlling the elevation of a gun barrel. Two telescopic members are provided, one being secured to the gun base and the other to the gun barrel. The first and second parts define a first piston and a hollow piston rod attached thereto with the first piston being slidable in a cylinder defined by the second part. A second piston having an associated rod is also provided and such second piston is slidable inside the first piston rod. First and second chambers are thus formed, the first being filled with an incompressible fluid such as hydraulic fluid and the second chamber is filled with a highly compressible fluid such as a gas.
