Abstract: In the case of a multi-cell accumulator battery, the plate stacks in the cells are provided with in each case two pole links and with in each case one connecting bolt on each pole link. The prefabricated battery cover is provided with openings (which are allocated to the connecting bolts) and a potted lead bush in the wall of each such opening. In addition, it has potted cell connectors and end-pole shafts in order to make it possible to pass power between two cells of the accumulator battery via in each case one connecting bolt of these cells and in order to make it possible to pass power between the end-pole shafts and the adjacent connecting bolt of an end cell. The connecting bolts are passed through their associated opening in the battery cover, and there is a welded joint between the lead bush in the wall of each opening and the connecting bolt. <IMAGE>

Abstract: In a lateral channel pump, the rotor blade compartments of a ring of blades in the rotor alternate in length, toward the center of the rotor, between long and short rotor blade compartments. The associated lateral channel has an outer contour concentric with the center of the rotor and an inner contour which tapers helically towards the outlet port. At the inlet point of the lateral channel, a partial circulating current is separated from the main circulating current as a result of the longer blade compartments. The partial current, due to its higher speed, causes the main current to circulate more rapidly between the rotor blade compartment and the lateral channel. As a result, the main current is accelerated and a higher level of efficiency is obtained.

Abstract: Compressor operation for regulating the gas pressure in a compressed gas volume (106) connected to the compressor (101). A brushless AC motor (23) is directly connected to the compressor, which is driven at the same speed as the motor. The pressure in the gas volume (106) is detected by a pressure-sensing device (109) that is connected to a converter (114). The converter simultaneously changes the amplitude and frequency of the driving voltage supplied to the motor (23). This is done in response to pressure changes in the volume (106). The motor is stopped if pressure exceeds a preset maximum value. The pressure in a compressed gas tank (104) is relieved upon motor stop to allow restart without counterpressure on the compressor. The device (44) for regulating the amplitude and frequency of the driving voltage ensures that the current at normal speed and full load is never exceeded upon motor start.<IMAGE>

Abstract: The invention comprises a method of attaching a load-bearing strut to a chair leg, or more generally to a post. The innovative aspect of the method is that the strut is curved before the attachment location and that this extension past the post brings it to rest approximately at the side of  the post's centre and in a specially designed fitting well to the side of the post. Increased gripping power at the attachment point ensures that the strut can be made thinner than would be otherwise possible. Stacking chairs, which are produced according to the method, are also covered by the invention.<IMAGE>

Abstract: For the purpose of separating coarse particles from a liquid such as water, e.g. in the cellulose industry, laundries etc., a vertical container is used in which a nozzle receives liquid from a pump and sprays the liquid in the form of a conical liquid jet up against the underside of a screening cloth. Above this cloth there is an outlet for the liquid, coarse particles impinging against the cloth and falling back to the bottom of the container. In accordance with the invention the total flow from the pump and jet is led off via the screening cloth and outlet above said cloth, the liquid level in the container being disposed between the nozzle and the screening cloth so that the liquid jet is sprayed through a layer of the liquid in the container before reaching the screening cloth.

Abstract: A three phase core form transformer for use in a three phase dual dynamic stabilizer system that provides reactive power compensation. The transformer has a three legged magnetic core, a plurality of primary windings corresponding to the phases, two auxiliary secondary windings per phase that are wound to provide first and second common bifilar portions, and a plurality of principal secondary windings corresponding to the number of primary windings. The first common bifilar portion, the principal secondary winding, the second common bifilar portion and the primary winding are placed coaxially and radially adjacent, in the recited order, starting from each leg of the magnetic core. The primary windings are connected in delta. The principal secondary windings and auxiliary secondary windings are connected in a forked wye wherein one auxiliary secondary winding of each of the other two phases is electrically connected to the free end of each of the wye connected principal secondary windings. This results in all three phases being present in each combination of principal secondary windings and auxiliary secondary windings. With this arrangement of windings the leakage reactance of the principal secondary winding and the common leakage reactance of the auxiliary secondary windings attached thereto for each phase are positive in value with the leakage reactance of the principal secondary winding being made to be about twice that of the common leakage reactance of the auxiliary windings. The primary windings can be continuous wound windings with the principal secondary windings and the auxiliary secondary windings being helitran wound windings.

Abstract: The invention relates to a method and to an arrangement for rapidly controlling the frequency of a radio-receiver which receives signal-sequences which have been subjected to interference and which include a synchronizing-sequence and a data sequence. The signal-sequence is converted in an A/D-converter to provide signal-points (ET) which are intended for analysis, and a Viterbi-algorithm (10) is adapted (12,13) with the aid of adaptation signals (U1<K>) obtained from the synchronizing-sequence of the prevailing interferences. The data-sequence is Viterbi-analyzed through a large number of calculating stages, for the purpose of determining the bit-sequence (S1) of the data-sequence. According to the invention the signal-point (ET) is branched-up to branch-signal points (ET), the number of which is equal to the number of states of the Viterbi-algorithm (10). Each individual branch-signal point is phase-shifted (20) to a corrected signal-point (ET,1) and is compared (21) with its adaptation signal (U1<K>), which has separate (K) signal points. Distances ( DELTA ST,1<K>) and angular deviations ( DELTA  phi T,1<K>) are calculated between the corrected signal-point (ET,1) and the adaptation-signal (U1<K>) signal points. A transition (K<1>) is selected through the Viterbi-algorithm (10), with the aid of the distances ( DELTA ST,1<K >) and the angular deviation ( DELTA phi T,1<K>,) corresponding thereto is selected (22). Selected angular deviations ( DELTA  phi T,1<K>) for successive incoming signal-points (ET) are low-pass filtered and integrated (22) to form a phase correction signal (V) through which the phase of the successively incoming branch-signal points (ET) are shifted (20). Corresponding phase correction signals are calculated for the remaining states of the Viterbi-algorithm (10).
