Abstract: ABSTRACT An orthogonal code division multiple-access communi-cations system comprised of a plurality of transceivers respec-tively employing orthogonal noise code mate pairs of a type having autocorrelation functions upon detection which when linearly added together compress into a lobeless impulse and wherein the same single time slot is utilized by all of the users in the system. Each user is assigned a different unique noise code pair consisting of code mate pairs that are selected from a subset of multiplexed noise codes whose crosscorrelation function value is equal to zero at a time when all the code mate pairs compress to an impulse, i.e. .gamma. = 0. The described arrange-ment enables random access, or direct call-up, to be accomplished with no interference between the users while using different noise codes for each user.

Abstract: (57) ABSTRACT OF THE DISCLOSURE            The present invention seeks to provide a method for treating the cell-ulose obtained from the cellulose cooking process for paper-making purposes.  According to this method, the cellulose is separated from black liquor or other similar waste slurry produced in the cooking process by means of compression and washed, bleached and dried, and an essential feature of the present invention is that all the phases of treatment are carried out in a pressure filter (4).  The treatment is performed so that black liquor or similar waste slurry is first com-pressed from the cellulose pulp slurry, whereafter the resulting cellulose cake is washed by conducting washing liquid into the filter, after which the cellulose is bleached by treating the cake with one or several bleaching chemicals led into the filter and by rewashing, if necessary, the cake between the various bleaching phases, and finally, the cellulose cake is dried and removed from the filter.

Abstract: INVENTORS:  SANDRO ARABIAN and MANFRED BAUMANN            INVENTION:  METHOD OF, AND APPARATUS FOR, RETRACTING THE LOOPS             AND ENDS OF TOWELS INTO A TEXTILE TOWEL DISPENSER     ABSTRACT OF THE DISCLOSURE     In known textile towel dispensers the clean towel is manually pulled out at the front,  the used towel is automatically drawn in at the rear, and the end of the towel hangs down vertically when the roll of clean toweling has been used up.  The hanging towel end, as has been found in practice, is undesirably repeatedly used by many individuals.  This disadvantage is eliminated by the inventive towel retracting apparatus.  With this apparatus the disadvantage that the towel loop freely hangs out from the towel dispenser is also eliminated, because the towel loop is drawn up to the dispenser a few seconds after the hands have been dried.  The inventive towel retracting or retraction apparatus contains a towel loop loaded with a weighted roller and concealed by a cover which can be part of an enclosure.  The used toweling or towel section is thereby pulled behind the cover where it can neither be seen nor reached by the user.  A delay mechanism ensures that the towel loop, which is partially pulled out from the towel dispenser and partially pulled out from behind the cover, remains stationary for a few seconds before it is retracted behind the cover.
