Abstract: Case 1-11746/+            Process for the preparation of foam-controlled detergents Abstract of the Disclosure The present invention relates to a process for the preparation of foam-controlled pulverulent detergents. In this process (a) 80 to 99,9 parts by weight of a pulveru-lent, water-soluble, non-surfactant constituent of the detergent are mixed homogeneously with (b) 0.1 to 20 parts by weight of silicone oil or silicone oil/silica mixtures, which are homogeneously dispersed or dissolved in a sol-vent, the solvent is then removed and the residue is mixed with further constituents necessary for the preparation of a detergent.        If desired, the detergent can also be treated as a whole with component(b).     The process enables the detergents (washing powders) of any desired foam capacity to be prepared.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for preparing a cationic starch dispersion wherein an alkaline, gelatinized starch is reacted with a cationic reagent such as a monomeric halogenated alkyl or alkenyl amine either concurrently with, or subsequently to, the cooking process resulting in a product in which the cationic reagent is chemically bound to the starch molecule.  The process provides a single relatively inexpensive starch product which is conducive to on-site preparation of a number of cationic starch derivatives which can be utilized without additional treatment as a papermaking adjunct, textile size, waste-water treatment or tailings flocculent, etc.  The process has reduced reaction times and improved efficiency over known processes.

Abstract: HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD           (D#76,642-F) ABSTRACT OF THE DISCLOSURE The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injection well and one producing well, with an infill well which is in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well; then converting the infill well from a producer to an injector and injecting steam into the lower portion of the formation via the infill well and recovering fluids from -the production well.  Two separate communication paths are established, one between the surface and the upper half or less of the formation, and one between the bottom half or less of the formation in the producing well, or in the infill well, or injection well, or combination of two or more thereof.   A fluid having lower mobility than steam is injected into the upper part of the formation via one or more of the communication means after steam override has begun, to resaturate the steam swept zone with the low mobility fluid to prevent further steam flow therethrough and force steam to flow into unswept portions of the formation.                             -I-

Abstract: -  A B S T R A C T  -PROCESS FOR COATING THE INNER WALL OF A FURNACE OR                     LIKE APPARATUS.            In this process, there is carried out first of all, through orifices (3) formed in the wall of the apparatus and by means of a suitable device, the injection of a first product (5) for filling in the vicinity of the inner face of this wall the porosities of the charge and forming a whole with this charge.  After a suitable period of time which ensures that the afore-mentioned effect is achieved, there is injected a second product (7) which must form the permanent coating under sufficient pressure to be able to slip between the inner wall (2) and the first coat (5) previously formed by taking advantage of the compressibility of the charge.          In this way it is possible to spread in a substantially uniform manner on the inner wall of the furnace a product which is capable of constituting the lining.  This product is closely applied to the inner wall owing to the pressure of injection without this product contacting the charge of the furnace, the latter having preformed in the course of the operation the function of the necessary temporary form.          Application in particular in blast-furnaces.

Abstract: VIDEO PLAYER/RECORDER WITH NON-LINEAR MARK LENGTH MODULATION                       ABSTRACT      In a video disk system a mark along a record data track is modulated in length to represent multi-bit binary code blocks of a first length (such as three or four bits) and the player system associated with the disk operates in multi-bit code blocks that axe generally longer (for example eight bits) so that two marks on the disk may represent a single code block in the associated system.  The bits of the code block in the associated system are assigned to bit positions of the appropriate number of marks on the disk in a way that minimizes the effect of errors in the operation of initially writing or subsequently reading a mark.  The increments of mark length are also made non-linear to further minimize the effect in the associated system of errors in mark length.

Abstract: TIRE CARCASS ASSEMBLY               Abstract of the Disclosure Method and apparatus for assembling a tire carcass comprising a precarcass band and a pair of inextensible bead rings.  me band is built and consolidated on a form having a rigid cylindrical surface.  me band in-cludes at least one cord or wire-reinforced ply and one or more tire liners of a rubbery gum, and may include additional tire components, in particular the components which will form the sidewalls of the tire.  The band is removed from its building form and then moved axially freely over a shaping apparatus.  An axially narrow cen-tral part of the band is expanded sufficiently to resist axial displacement of the band, which is then spread and smoothed outward from its central part by expanding and then moving outwardly a pair of expandable spreading elements.  Following the spreading operation, end regions of the band are expanded to seat the prepositioned inex-tensible bead rings, after which the bead rings are moved axially toward each other and the band therebetween is expanded by air pressure into engagement with a circum-ferentially restricting ring or belt.  With the carcass so expanded, the band endings are turned outwardly about the bead rings by turnup bladders while a pair of annular inner support bladders exert circumferentially uniform axially outward counter-force to squeeze the respective beads.

Gas and liquid are fed through the motionless mixer to predisperse the two phases, and the impeller agitator maintains the dispersion for a time sufficient for mass transfer to occur.  Significantly less power is required for the impeller agitator to maintain the dispersion produced by the motionless mixer than is required to produce an equivalent level of dispersion with an impeller agitator operating with a gas sparge ring alone.

Abstract: ABSTRACT            A method for measuring substantially spherical particles, such as dust. Two signals arc formed, one of which is an approximately linear function of the particle concentrat-ion independently of the particle diameter and the second one is an approximately linear function of the particle diameter independently of the particle concentration. In order to obtain these signals the particles are illumin-ated with light in a direction different from their direct-ion of flow. At least two detectors are arranged in such a way that the light in the beam path from the light source (3) to the first detector (6) is substantially only in-fluenced by scattering and by light absorption of the particles and that the light in the beam path from the light source to the second detector (7) passes substant-ially only via reflections against the particles. The two signals are formed by definite relations between the d.c. voltage components of the output signals of the detectors and the average value of the squared R.M.S. value of the a.c. voltage component of the output signal from one of the detectors.
