Patent EP-0256533-B1 (EP)
IPC: C01B21/40
Filed: 1987-08-13
Granted: 1992-10-28
Abstract: The present invention relates to a method for reducing the content of nitrogen oxide, especially nitrogen dioxide, in the effluent gases from an absorption column for manufacture of nitric acid and an apparatus for carrying out the method. The absorption in the upper 1-8 stages, preferably the upper 2-4 stages of the column, is carried out at a relation between the contact area in the liquid level for absorption on the plates and the free gas space for oxidation of 1,5-5, preferably of 2-3, larger than the corresponding relation for the horizontal plates further below. The relation between the contact area and free gas space is adjusted by increasing the overflow height for the liquid volume on the upper plates. Said relation can also be adjusted by reducing the distance between the upper plates. The apparatus comprises an absorption column (1) having horizontal plates (6) with a liquid level (a,b) and oxidation spaces (9) between the plates (6). The overflow height on the 1-8 upper plates (6) in the column can be regulated to give a liquid level (a) 1,5-5 times the liquid level (b) on the plates (6) further below in the column, preferably (a) = (2-3).(b). The semispherical part (2) of the column (1) is separated from the upper oxidation volume (9) by a non-perforated plate (4). The two volumes (2,9) are in communicating via openings (10) between/in the plates (4). A pipe (3) through the semispherical part (2) can transport the effluent gases out of the column (1).

Abstract: A method of distributing the processing load among components of a multiprocessor system, such as a switching system, avoids having two different processors (CP9) simultaneously handling different jobs for the same connection. A plurality of central processors (BP,CP,IOC) and a central main memory (CMY) are connected in parallel to a central bus system (B:CMY). As soon as they are free, each processor fetches a job for handling a switching task from a job registering means (AR), and then fetches data about the appertaining connections from the main memory (CMY). Each processor stores a protective code corresponding to its address at a location associated with the job as soon as and as long as it is handling the job. However, it does not store its code in case a different processor (CP9) has already entered its protective code there. Every central processor has its own job memory (AS). When a processor finds the protective code of another processor associated with the job data, it forwards its own job to this other processor by entering this job into the job memory (AS) of the other processor.

Abstract: A boring tool (30) mounted on the spindle (10) of a boring machine is adapted for automatically producing a first bore (12A) and measure the diameter thereof prior to boring a relatively larger second bore (12B). The tool (30) includes a computer (40) storing the values of demanded first and second diameters, and programmed to determine the difference between the measured first diameter and the demanded second diameter, this difference being added to the demanded first diameter to produce a weighted target diameter (WTD4), whereby account is taken of the cutting error due to deflection of the tool while cutting the first bore (12A). The tool (30) includes a stepper motor (38) adapted to position the cutting bit (32) of the tool (30) in accordance with demand signals from the computer (40) identifying the diameters to be cut. The computer (40) can only identify a diameter in comparative terms i.e. in terms of a number of steps of the motor (38). If a diameter is to be known in absolute terms, the diameter e.g. of the first bore (12A) is measured independently of the tool (30) by a probe temporarily mounted on the spindle (10) whereby the diameter of the bore can be determined in terms of, say, micrometers by a computer (20) provided on the machine. The probe-measured value of the diameter is transmitted to the computer (40) of the tool (30) by an optical communication link (50) to provide the latter computer (40) with a reference identifying the diameter in absolute terms.

Title: Method of testing cores
IPC: G01N3/10
Filed: 1988-09-09
Granted: 1993-07-28
Abstract: The present invention relates to a method of testing the loading capacity of cores and is especially suitable for testing cores used in the paper industry which are made of board by glueing and reeling.   Hitherto it has not been possible by means of known methods to simulate the real stresses occurring in use of a core. Therefore, even the best results have been incomplete and unreliable giving only an outline of the real loading capacity of the core. The method according to the invention is characterized in that the core (9) is rotated on the chuck (8) is loaded with a roll (11), the stress force of which against the surface of the core is completely adjustable. The changes in the structure of the core during the testing are registered, e.g. by an optical source of a light and sensor arrangement (15, 20), which gives a signal according to which the temporary stress force and rotational speed are registered.

Title: Spacer for two layers of reinforcement mats
IPC: E04C5/18
Filed: 1988-04-06
Granted: 1991-06-05
Abstract: The spacer possesses carrying legs (1) which are arranged in a first plane and supporting legs (3) which are arranged in another plane, the two planes forming an acute angle. At the junction of the two legs, a web (5) is fastened in order to carry the upper reinforcement mat. Carrying limbs (6) with hooks (7) are arranged in the plane of the supporting legs (3) in order to receive the lower reinforcement mat. In order to increase the stability of the holder when loaded by the lower mat, the supporting legs (3) are bent inwards at the bottom, the bends (10) lying somewhat above the apex (8) of the hooks (7), as a result of which the resulting force acts on the carrying legs (1) in the direction of the bearing surface. To increase the carrying capacity of the hooks (7), the supporting legs (3) and the carrying limbs (6) are connected to one another by a strut (9). Such a spacer exhibits, with the same wire thickness, improved stability and a higher carrying capacity than previously known holders, and additionally facilitates the laying of the upper reinforcement mats. <IMAGE>

Abstract: The invention relates to a method and a device for controlling the strip width during the hot-rolling of strip on a multiple-stand finishing line of a rolling mill train in which the speeds of the working rolls of each stand are controlled as a function of the instantaneous operating state. Here, the strip widths are sensed directly after the last reduction per pass and/or before the penultimate reduction per pass and are compared with the desired width in a width controller. In the event of deviations, a strip-supply controller for the strip supply between the last stands is acted upon, which strip-supply controller, by adjusting the roll nips, corrects the strip supply and the tensile stress of the strip in such a way that the strip width changes. The method is optimized by additional control of the strip thickness according to the novel strip-supply principle as well as by dispensing with some loop lifters. <IMAGE>
