Abstract: ABSTRACT         The present invention relates to cellulose ethers which can be dispersed in aqueous media and to a process for preparing them by reacting water-soluble cellulose ethers with a modifying agent.  The modifying agent is a silanc, R-R4, in which R is of the formula -IMAGE-and wherein R1 is alkyl having from 1 to 4 carbon atoms, alkenyl  having from 1 to 4 carbon atoms or carbocyclic aryl having one or two 6-membered rings, having up to 15 carbon atoms (including aliphatic side groups) and optionally being ring substituted by a member selected from the group consisting of chloro, bromo, alkoxy having from 1 to 4 carbon atoms, carbocyclic aryloxy having one or two 6-membered rings and up to 15 carbon atoms (including aliphatic side groups) and phenyl; R2  is -H, one of the meanings of R1 or one of the meanings of R4;         R3  is one of the meanings of R2; and R4  is alkoxy having from 1 to 4 carbon atoms and being optionally substituted by a member selected from the group consisting of alkoxy having from 1 to 4 carbon atoms and carbocyclic aryloxy having one or two 6-membered rings and up to 15 carbon atoms (including aliphatic side groups); aryloxy having one or two 6-membered rings and up to 15 carbon atoms (including aliphatic side groups) and optionally being substituted by a member selected from the group consisting of alkoxy having from 1 to 4 carbon atoms and aryloxy having one or two 6-membered rings and up to 15 carbon atoms (including aliphatic side groups); aliphatic carboxylic and acyloxy having up to 5 carbon atoms, aromatic carboxylic acid acyloxy having one or two 6-membered carbocyclic rings and up to 16 carbon atoms; 0-R; or N1-1-R. The modified cellulose others can be worked into aqueous media of a broad pH range (from strongly acidic to strongly alkaline) without lump formation, the viscosity build-up of which can be precisely adjusted and controlled by simple technical means during and after the working-in phase where they are dispersed, and which (even by addition of small amounts of an appropriate modifying agent) can be converted  into reversible types of modification.

Abstract: ABSTRACT           A steam generating furnace which burns high moisture content fuel has a panel of heat absorbing tubes dividing it into two vertical interconnecting passageways:  (a) a combustion chamber for burning the predried fuel and (b) a drying shaft for extracting moisture from the fuel.  Wet fuel is introduced near the top of the drying shaft.  As it falls it is dried by some of the hot gases diverted from the top of the combustion chamber into the top of the drying shaft.  The cooling of the hot combustion gases due to evaporation of moisture from the wet fuel causes a difference in density between the gases in the two passageways, creates a natural, unidirectional circulation of part of the combustion gases from the top of the combustion chamber to the drying shaft.  Predrying the wet fuel causes the fuel to burn faster and hotter thereby producing a stable and efficient combustion of the wet fuel at higher specific combustion rates.  Recirculation of the cooled drying gas through the combus-tion chamber reduces the generation and emission of particulate and gaseous pollutants.

Abstract: DRAINAGE TESTER                    ABSTRACT OF THE DISCLOSURE The drainage quality of a pulp furnish slurry on a paper machine forming wire is predicted by the drainage tester of this invention by accounting for the effect of drainage through the paper sheet as it forms.          The tester can distinguish between fast draining mechanical pulps and slower draining chemical pulps as well as predict the effects various additives will have on drainage. The apparatus includes a screen which separates furnish fibers from the slurry white water in response to a constant volume vacuum pump. Pressure differential as a function of time is recorded producing for any given furnish three distinctive points of inflection on the curve, including a first point of inflection which correlates with the wet line on a paper machine forming wire, second point of inflection which correlates with the dry line on the former and a third point of inflection which correlates with the maximum practicable removal of water from said pad by the typical former vacuum systems.

Abstract: ABSTRACT Method of recognizing speech pauses.     The described method of recognizing pauses in a speech signal enables -this recognition also when a slowly varying noise signal is superposed on the speech signal. For the purpose of pause recognition so-called short-time mean values connected with a clock pulse are continuously determined from the samples of the disturbed speech signal, which short time mean values are a measure of the average power of approximately 100 ms long sections of the disturbed speech signals. The sequence of these short-time mean values is then smoothed by linear filtra-tion or by means of a median filter. In parallel with the smoothing operation an estimate for the noise signal power averaged over a few seconds is taken from the sequence of short-time mean values. If the smoothed short time mean value is once or several times less than a threshold which is proportional to the above-mentioned estimate, then it is decided that there is a speech pause.

Abstract: ABSTRACT         An improved tote box especially adapted for use within an automated storage and retrieval system is provided with a bumper rim a short distance from the tote bottom to reduce the moment arm created when the box engages another box or the like.  Stacking stops are integrated with the bumper rim to provide additional strength, and the stops circumscribe side drains to allow fluid to be drained without flowing into a lower box in a stack.  A divider grid is provided and includes intersecting crosswise and lengthwise divider plates, each Z-shaped and each having mounting slots in one edge and notches in the other.  When the plates are mated by seating the slot of a lengthwise plate in the slot of a crosswise plate, the opposing bosses at the mouth of each slot of each plate seat in the notch of an inter-secting plate.  Tabs on each end of each plate seat in slots in the tote box walls and a ramp overlying the notch restrains the divider plate tab to secure the grid in the tote box.
