Abstract: The invention refers to a device for separating a surface layer of a liquid by a container submerged in the liquid. The container includes a bottom, a wall member, connected to the bottom and having a variable length, and a separating member, which is connected to the wall member and communicates with a space in the container via an opening. An overflow portion of the separating member is located below a free liquid surface of the surface layer and permits the flowing of liquid. A discharge conduit extends from the space for liquid discharge. A floating member, connected to the separating member, floats on the liquid outside the container and exerts a lifting force upon the separating member in a direction prolonging the wall member. A submerging member is connected to the separating member and located below the over flow portion. The submerging member has a mass and exerts a downwardly directed force, so that the overflow portion is located below the free liquid surface, and a lifting force due to liquid pressure when the space has been filled with such a quantity of liquid that the submerging member partly is located in the liquid, wherein the overflow portion will be above the free liquid surface.

Abstract: An optical transmission system arrangement for transmitting data between two relatively rotatable parts. A hollow cylinder with a mirror-coated inner surface onto which the light is incident at the smallest possible grazing angle and is frequently reflected. The light is coupled in and out through a coupling section in the hollow cylinder, at which the light is incident onto the inner surface. The system achieves a comparatively low damping because the reflecting power at small angles of incidence is comparatively high.

Abstract: The tensile straightening device described comprises a braking truss (6), a pulling truss (7) and a truing head (8) situated between the two. Each truss has an inner roller (1 resp. 4) and an outer roller (2 rep. 3) the later-named rollers are rotatably mounted on their own rocker frames (9, 10), which are pivotably mounted in the machine stand. The rollers in both trusses can be pressed towards each other through the tensile force of the belt, increasing the torque transmission capability of the rollers. In order to set the necessary speed differences between the rollers in each truss, these are driven via a differential (108, 124), which also serves as a torque converter. Power transmission capability can thereby also be optimised. The difference in speed between the trusses is controlled by a planetary gear (119). A pinion (135) from a traversing motor (137) works toward an external gear ring (134) on the outer sun gear and is regulated with the selected speed relation from a pulse generator, which is driven by the belt (5) on the pulling truss (7) via a measuring roller. To avoid overloading the truss, the shaft gear (112) on the roller (4) on the outlet side of the truss (7) is connected via its torque rod to a tensile force sensing organ (load cell). If the signal from this indicates that the belt force has a tendency to exceed the permissible limit, the speed of the traversing motor is automatically reduced, thereby reducing belt force.<IMAGE>

Abstract: Water in a pipe circuit (1) is set in motion by a pump (2) to form a current with adjustable speed in a testing tunnel (3) with rectangular cross-section. The water speed can be regulated by fluid being pumped upwards from a compensation tank (5) into an open vessel (6) with an overflow edge (7). During use of the testing equipment, water is allowed to run over the edge and back to the compensating tank (5). Water is conducted to the testing tunnel (3) from the open vessel (6) placed in such a position that the height of the vessel open surface (8) above the open surface (9) of the compensating tank is such that the required flow speed is obtained. The testing tunnel is of transparent material such as plexiglass, and contains a test object (4) around which it is required to study the flow pattern, and the rotor with a shaft (11) closed at one end to which six tubular arms (12) are soldered in pairs. When the rotor is rotated by a motor (15) at adjustable speed, a vacuum is created at the rear ends of the arms, so that through the rotor shaft open end (13) air is aspirated to form bubbles in the water behind the rotor arms. The amount of aspirated air can be adjusted by a needle valve (16) in the rotor shaft open end.

Abstract: The alternating voltage produced by the oscillator (1) is connected over the winding (S) to be tested, and the instrument monitors and displays the electrical phase angle between the voltage and a current produced by the voltage through the winding. The oscillator produces a symmetrical first voltage, and a prim. component (9) monitors the current which this voltage produces through the winding (S) to convert it to a second voltage which is in phase with the current. A secondary component detects the zero passage of the two alternating voltages. From a time difference between the detected zero passages, the secondary component determines the electrical phase angle between the alternating voltage connected over the winding and the current through the winding, the viewing unit (13) displaying the thus measured phase angle.

Abstract: An encoding method in transmitting a plurality of parallel, independent and asynchronous data channels, each of which after encoding into serial from is to be supplied to an optical transmitter before transmission over a fibre-optic cable. The parallel data channels (D1-D4) are over-sampled, i.e. they are sampled several times per time slot and are time multiplexed in a series of frames (R1,R2,R3,...) the channels in one frame (R1) being retained with their true values (D1-D4) and in the successive frame (R2) being given their inverted values (D1-D4). In addition there are inserted fixed synchronizing bits (F1,F2) and a bit (T1) which alternates between a logical 0 and a logical 1, depending on whether the true or inverted values of the data channels occur in the frames. A parallel-series converter for carrying out the encoding method is described.

Abstract: The invention relates to a method and to an arrangement for cleaning the spark plugs of an internal combustion engine automatically subsequent to the engine stopping and then preferably after an unsuccessful attempt to start the engine, so that conditions for a successful starting attempt are made more favorable. Failure to start an engine is often due to the presence of deposits on one of the spark plugs, these deposits preventing an ignition spark from being produced in the cylinder. The invention method and arrangement solve this problem, by burning clean the spark plugs (11-14) immediately after the engine has stopped, and then preferably after the engine has failed to start. A detection means (5) establishes whether or not the engine has started, by sensing a suitable engine parameter, preferably engine speed, through a speed indicator (8). When the detection means (5) detects that the engine has stopped or has failed to start, a signal is sent to the control unit (3), which subsequently causes the ignition system (2) to generate a shower of sparks in close succession on all spark plugs, either in parallel or in one cylinder at a time. The spark showers burn-off any deposits on the spark-plugs.

Abstract: The framework for the press of a papermaking machine or the like includes interconnected opposite side frames each having two columns. Each column on the operational side of the machine has a section that is removable to permit exchange of an endless press felt and/or other belt extending through the press nip. All four columns are axially prestressed with a force exceeding by a safety margin the tensile force induced in the respective column during operation of the press. The columns preferably are box beams. They are prestressed by hydraulic nuts connected to tension rods disposed within and extending axially of associated ones of the columns. The tension rods in the columns having a removable section are formed in two parts interconnected by a quick connect/disconnect coupling that is located proximate to the removable column section. Disengagement of the coupling permits movement by an actuator of one of the two rod parts away from the other and from the removable column section.
