A technical method for drying, crushing and grinding mussel shells and seashells and the like. It has not earlier been technically possible to recover lime-rich mussel shells and seashells by powdering the shells. In brief, the technical solution comprises drying the shells, crushing the shells and grinding the same in a mill provided with hammers and gratings. A grinding process in which the circulating unfinished product is an important part of the system circuit. The finished product is delivered by a screw feeder to bulk or large sacks from a mobile plant constructed to this end.

The present invention relates to an arrangement and a method for ensuring quality during scanning/copying of images/documents. The method includes the steps of feeding in the page(s) that are to be scanned/copied. Thereafter, a first measurement of outer characteristics is performed with respect to skew, double-feeding/overlapping, deviating shape, and geometric deformation for calculating a first quality measure Q1. Thereafter, the first quality measure Q1 is compared with a predetermined first quality limit Q+1. If Q1≥Q+1, then an automatic adjustment is performed in the form of a geometric transformation in order to improve the first quality measure Q1. Thereafter, the contents of the page are analyzed with respect to structure and objects in order to calculate a second quality measure Q2, which is compared with a predetermined second quality limit Q+2. If Q2≥Q+2, then image improvement methods are performed on each identified object. Thereafter, an information analysis of each page is performed, followed by a comparison with pre-defined form/document types for calculating a third quality measure Q3, which is compared with a predetermined third quality limit Q+3. If Q3≥Q3, then a fourth quality measure Q is calculated, which is an overall quality measure that is compared with a predetermined fourth quality limit Q+. If Q≥Q+, then pre-processing is performed in order to achieve a correct output format, depending on pre-defined information about the printer/output unit.
摘要:
A vehicle timber bank arrangement having a horizontal supporting beam (1) and generally vertical post assemblies (2, 4 and 3, 5) mounted at respective ends of the beam. Each post assembly includes a bottom post (2, 3) anchored firmly to the beam, and at least one top post (4, 5) which is displaceable telescopically to its associated bottom post. A pivotal upper connection means (15) is pivotally mounted at at least the first top post (4), and at the second top post (5) there is mounted a device (22) for coupling with the upper connection means when this device is in a position in which it connects or binds the two top posts. The upper connection means is swung by a piston-cylinder device (6, 7) which functions to displace the first top post telescopically in relation to the first bottom post. The first top post (4) and that part (7) of the piston-cylinder device (6, 7) which actuates the first top post are coupled together by means of a rack-and-pinion arrangement.
摘要:
A method for the continuous production of boards of a ligno-cellulosic fiber material wherein the material is broken up into particles and/or fibers. These are dried, glued and formed to a mat. The mat is compressed to a finished board while steam is introduced. According to the present invention, the compression is performed as a single step and the steam is introduced through one or many compression rollers. By injecting steam in this way a sufficient cure is obtained to withstand the spring back characteristics inherent of the fibers so that it is possible to obtain a finished thickness of the board with one single compression step.

A method pertaining to the baking of products (B) in a baking oven (1) in which the products are supported by at least one rotary oven trolley (17) comprises rotating the trolley through a number of revolutions in one direction (R1) during the baking process, and thereafter reversing the direction of rotation and continuing rotation of the trolley through several revolutions in the opposite direction (R2) before again reversing the rotation of direction of the trolley. The trolley (17) keeps one and the same axial position in both directions of rotation. An arrangement for carrying out the method includes a drive means (20-26) for alternating rotation of the oven trolley through an equal number of revolutions in two mutually opposite directions during the baking process.

A heat exchanger unit (13) for recovering heat from the flue gases from a cylinder steam boiler (10), said heat exchanger unit comprising a flue-gas tube (14) and a heat-exchanging tube (16) which is supported concentrically inside the flue-gas tube (14) by a bent inlet pipe (19) extending from a lower opening (20) in the peripheral wall of the flue-gas tube (14) to an inlet opening (21) in a lower outwardly bulging end wall (22) of the heat-exchanging tube (16), and an outlet pipe (23) extending from an outlet opening (24) in an upper part of the peripheral wall of the heat-exchanging tube (16) to an upper opening (25) in the peripheral wall of the flue-gas tube (14). The inlet pipe (19) has a first, horizontal, straight end portion (19A), a second, upwardly directed, straight end portion (19B) and also an intermediate, curved portion (19C). The bending angle (α) of the curved portion exceeds 90° and the other end portion (19B) extends with an inclination determined by said bending angle (α), towards the centre of curvature of a partially spherical portion of the lower end wall (22) of the heat-exchanging tube (16), in which wall the inlet opening (21) is arranged eccentrically in relation to the central longitudinal axis of the heat-exchanging tube (16).

The invention relates to a method for manufacturing booklets, each booklet comprising a cover made up of two cover sheets and a spine therebetween, a bead of glue attached to the inside of the spine, a sheaf of papers inserted between the two cover sheets, one side edge of the sheaf being connected with the inside of the spine by means of the bead of glue. The method comprises the following steps: a) moving a sheaf of papers (B) by means of a first power operated transport means (3) to a first position, b) moving one of several covers (A) with attached bead of glue, which covers are located adjacent each other, by a second power operated transport means (5), to a second position at a distance from the other covers, c) bringing said sheaf of papers in contact with said cover with bead of glue, such that the sheaf of papers will be enclosed in the cover, said side edge of the sheaf of papers facing the bead of glue, and d) moving the cover containing a sheaf of papers past an activation device (7), which will activate the bead of glue so as to connect said side edge of the sheaf of papers to the inside of the spine. The invention also relates to a device for carrying out the method, a cassette (K) containing covers for use in said device, a method for filling the cassette as well as a method and a device for jogging up the sheaf of papers.
摘要:
To avoid leakage in concrete structures with dilatation joints and to prevent dirt from accumulating in the joints there has been developed a dilatation joint element which is easy to mount, reliable and essentially maintenance-free. The dilatation joint element according to the invention is comprised of opposed, longitudinal angle elements (1, 2) interconnected in pairs and made of metal with interposed jointing compound (7), reinforcement bands (3, 4) and rubber elements (5, 6). With curved band sections and rubber elements between the angle elements and a curved jointing compound section which is attached to the upper band section there is provided a supporting, power-compensating and power-distributing function when the joint is subjected to load, both at compression, expansion and shearing, providing a tight, reliable and loadable joint with good fatigue strength.
