Abstract: In an arrangement for jointing together adjacent pieces (1, 2) of floor covering material, mutually facing edge portions of the pieces (1, 2) in a joint are profiled such that the one piece (1) has a groove-shaped accommodation space (5) in which a corresponding bead-shaped projection (6) on the other piece (2) may be accommodated. The one piece has a flocking (9) which is disposed for holding together adjacent pieces. The profiling has, besides the accommodation space (5) and the projection (6), mutually facing surfaces (7, 8) on both pieces (1, 2, respectively), at least one of these surfaces being flocked (9). The flocking (9) or flockings (9) are located outside the defining surfaces of the accommodation space (5) and the projection (6).

Abstract: A face-milling tool includes a milling body forming seats arranged around an axis of rotation of the body. The seats carry identical inserts, each insert being of tetragonal or pentagonal, or hexagonal shape. Each insert includes first and second side faces. Each side face includes a pair of minor cutting edges at each corner of the insert. Two major cutting edges intersect respective ones of the minor cutting edges whereby each major cutting edge and its associated minor cutting edge together form a cooperating pair of cutting edges. There are two of those cooperating pairs at each corner of each side face, whereby there are at least sixteen cooperating pairs on the insert. The minor cutting edges, which function to generate a surface on a workpiece, are sharper than the major cutting edges. During a milling operation the insert is oriented so that only one cutting corner engages a workpiece, and only one of the cooperating pairs of cutting edges of that cutting corner is active.

Abstract: The invention relates to a process for the production of paper from a suspension of cellulose containing fibres, and optional fillers, which comprises adding a water-soluble cationic or amphoteric branched acrylamide-based polymer and an anionic aluminium-containing silica sol to the suspension and forming and draining the suspension on a wire.

Abstract: In a system for jointing together of adjacent pieces of flooring material by means of grooves (3) and tongues (4), at least one of the opposing surfaces on the tongues (4) and the grooves (3) of the pieces display flocked surface portions (10-13). The flocked surface portions (10-13) extend along the tongues (4) and/or the grooves (3) and cover substantially their entire length. The fiber length (9) of the flocked surface portions (10-13) exceeds the difference between the width of the grooves (3) and the thickness of the tongues (4).

Abstract: Aqueous suspensions of colloidal particles which particles are both silica based anionic particles and swollen particles of clays of smectite type which are expandable in water and a process for the preparation thereof. The suspensions are useful as flocculating agents and particularly in combination with polymers in the production of paper.

Abstract: Silica sols with a high content of microgel and particles with a specific surface area within the range 300 to 700 m.sup.2 /g, preferably 400 to 650 m.sup.2 /g. The sols can be prepared by acidification or a water glass solution and alkalization at a certain dry content, alternatively to a certain pH. The sols are particularly suitable for use as additives in papermaking in combination with cationic polymers and especially in combination with cationic acrylamide based polymers.

Abstract: A shank carries a milling tool and has a clamping portion adapted to be mounted in a bore of a chuck. The chuck has first and second locking screws which are engageable with first and second recesses, respectively, formed on a cylindrical outer surface of the clamping portion of the shank. The first recess is configured such that the first locking screw urges the clamping portion into the bore to press a surface of the shank against the chuck. The second recess comprises first and second longitudinally adjacent planar surfaces which form an angle with one another. Depending upon the angle of inclination of the second locking screw (that angle varies in different types of chucks), the second locking screw will flushly engage one or the other of the surfaces for preventing rotation of the shank within the bore.

Abstract: In a method of making a glazing pane (1), printed with a decorative frame (15), in which the decorative frame (15) extends right to the peripheral surface (6) of the glass pane (1) independently of edge tolerances of the glass panes and of positioning tolerances of the glass pane and of the printing tools during the printing operation, a profiled strand (13), which extends the surface of the glass pane (1) beyond its peripheral face (6) is integrally formed immediately adjoining the peripheral face (6). The decorative frame (15) is printed on beyond the peripheral edge of the glass pane (1) and onto the profiled strand (13). After the printing ink has dried, the profiled strand (13) is removed from the glass pane (1).

Abstract: A valve connection array for mounting at a cabinet wall in a sealed cabinet for disposing a plurality of valve connection blocks in at least one row is disclosed. Each valve connection block includes a valve connection portion on a front surface for individually connecting a valve and associated connections ports on a rear surface for connecting pressurized medium conduits. At least one row of valve connection blocks define between opposite side surfaces thereof at least one inlet port and at least one outlet port for providing common inlet and outlet ports between juxtaposed valve connection blocks. The blocks include means for mounting the blocks in said row with said sides sealingly juxtaposed for defining said common inlet and outlet ports between blocks and with said blocks defining a common flat surface area substantially in the form of a rectangle around said row.

Abstract: The invention relates to a method and an apparatus for determining the specific fuel consumption of an internal combustion engine by measuring the change in weight of a pot containing fuel for consumption by the engine during a specific, selectable time. The apparatus for performing this method includes a data acquisition system equipped with a number of measuring points. Sensors at the measuring points feed, through the data acquisition system, signals representing the change in weight of the fuel pot, the speed of the engine and the torque of the engine into a computer. The computer is programmed for measuring at constant speed and constant torque, within selectable tolerances, and for measurement during a specific, selectable period of time. The method of the invention permits the use of statistical methods to assure reliable and accurate measurement results with the shortest possible measurement period, while providing high flexibility in interfacing with an operator or central computer system.
