Abstract: A spider bearing having a radial bearing and a thrust bearing wherein the inner ring of the radial bearing rests on the outside axial end of the pin through the use of a flange against the end of the pin while another flange, axially disposed from the first, forms the inner race of the thrust bearing. Therefore, axial force is introduced via the end of the pin. The root of the pin, therefore, remains free of slots or joints, and without contact with the inner ring and the thrust bearing, such that upon deformation under load, tilting of the race does not occur. Therefore, parallelism of the thrust bearing races is maintained and uniform load-carrying capacity of the bearing is assured. The spider may, therefore, be shaped more optimally in the region of the root so as to obtain greater strength.

Abstract: An arrangement for the positioning of an oil boom or similar alongside a ship (5). Amongst other things the invention permits the simple and effective positioning of oil booms at to all intents and purposes any point on and along the side of a ship, and in such a way that the boom is not directly attached to the side of the ship and yet is provided with an oil-tight connection, permits the positioning and connection of the boom/booms without the need for any fixed or permanent devices or fittings, or for operations having to be performed on the vessel, and makes it easier for the oil-receiving ship to steer and manoeuvre better and to bring the oil to or into the vicinity of the ship in the boundary layer of the ship and to collect the oil in this still water, where it is very much easier to operate the oil collecting devices directly from the ship, and also to dispense with the need for one ship in the sweeping manoeuvre, so as not to be dependent on combined operations by three ships, which has been found in practice to be to all intents and purposes unworkable. The boom in question can be attached to a number of cables (1) etc., running around the hull (4) of a ship on the side of the ship and is so arranged as to be held extended from the ship to form a collecting pocket.

Abstract: If the workpieces involved are steel plates, they can form part of a magnetic circuit through which flows a closed magnetic current. Where a break occurs in the circuit, e.g. in the form of a seam gap, a magnetic leak flow occurs which causes a magnetic polarisation of the seam gap edges. These magnetic poles attract the ferromagnetic powder, causing it to be positioned in or in the immediate vicinity of the seam gap. The strength of the magnetic current can even be used to contribute to a small amt. of additive material being applied. Alternatively, the workpieces can be magnetised in advance, possibly in a separate appts., so that a magnetic polarisation of the seam gap edges is guaranteed. It is also possible for work equipment such as fixtures to form part of the magnetic circuit.

Abstract: A method for the thermochemical surface treatment of workpieces in a reactive gas plasma is disclosed in which an appreciable reduction in the amount of reactive gas and energy used is achieved by working at gas pressures below 10 pascals (Pa). Particularly advantageous results are achieved with a low-voltage electrical arc discharge, which leads to an ionization of the gases used (about 50%) that is substantially higher than that, which is achieved with the methods described in the art 6 (approximately 1%). Surfaces, treated by such a conduct of the reaction, are distinguished by an increased hardness and better wear properties. The method of the invention moreover allows more numerous variation possibilities than do the methods described in the art and enables the conduct of the method to be adapted in a flexible manner to the specific requirements of the particular case. The inventive method permits a time sequence of the several treatment steps with different reactive gases or gas mixtures and thus a combination of different foreign elements in the treated substrate surface.

Abstract: The invention relates to a method and an arrangement for controlling the frequency of a radio-receiver which receives signal-sequencies which have been subjected to interference and which include a synchronizing-sequence and a data-sequence. A signal-sequence is A/D-converted (3) to signal-points (I,Q) intended for analysis, and a Viterbi-algorithm (10) is adapted (12,13) to the prevailing interferencies with the aid of the synchronizing-sequence. The data-sequence is Viterbi-analyzed through a large number of calculating stages, for the purpose of determining the bit-sequence of the data-sequence. According to the invention, a bit-sequence is extracted during the Viterbi-analysis, with a time-delay (TE), subsequent to effecting a few calculating stages, and a corresponding extracted signal-point is calculated (14). The analysis-intended signal-point corresponding to the extracted signal-point is divided and time-delayed (16,TE), and phase-compared (15) with the extracted signal-point. Corresponding phase-comparisons are made with respect to consecutive signal-points in the data-sequence and the angular magnitudes obtained in the phase-comparison are low-pass filtered and integrated (17) to form an angle-shift signal (V). The analysis-intended signal-points are displaced angularly (11) by the angle-shift signal (V) prior to the Viterbi-analysis.

Abstract: The invention relates to a method and a device for testing and supervising majority votes in a multiplane digital time selector with essentially identical equipment in each of at least three planes (A,B,C) working in parallel. An incoming data flow is distributed to the planes and is allowed to pass through the equipment in each of them and gives rise to outgoing data streams. These outgoing data streams are compared to each other and a majority voted outgoing data flow based upon the comparison is delivered from the unit. An error is periodically introduced in accordance with a predeterimed pattern in the three planes and the data streams arriving at the majority vote and the majority voted data flow are compared. If an error is then found in any of the data streams an alarm is emitted. If an alarm (LARM1) is expected that has been caused by an error introduced in accordance with the predetermined pattern, this alarm is identified based upon knowledge of the predetermined pattenr in order to distinguish from alarms, which result from errors not introduced in accordance with the pattern. <IMAGE>

The radiation value is computed on the basis of a ratio between the two generated electric signals. Adaptation of the signal intensity to a processing range is made, which constitutes a lesser part of the total intensity range of the signals generated by the radiation, by means of an amplifier device with a variable degree of amplification, by sensing the signal intensity after the amplifier device. The amplifier device is designed as a pre-amplifier which is maintained at a fixed degree of amplification and is in series therewith, terminal amplifiers, which are adjusted in their degrees of amplification in order to give the signals said intensity adapted to the operational range. By varying the signal processing, the method/instrument may be adapted for generation of measurement values correlated to parameters including kVp, X-ray dose, exposure time and curve-shape.
