Abstract: ABSTRACT OF THE DISCLOSURE               A method for reducing the viscosity and for refining crude kaolin clays is disclosed.  The inherent viscosities of crude kaolin clay ores, particularly those having accept-able optical and purity properties for use in preparing paper coating pigments, but normally rejected because of their high inherent viscosities, are significantly reduced by contacting an aqueous slurry of the crude clay with an inorganic polymeric complex having the general formula [AI(OH)yA3-y]x wherein x = 6 to 24, y = 1.0 to 2.75 and A is selected from the group consisting of Cl?, (SO?)0.5 and NO?.  In a prefer-red embodiment the above treated clay is also subjected to a high shear mixing action or kneading prior to further con-ventional processing procedures, such as fractionation, leaching, etc.  The treatment of the clay with the above polymer complex and high shear mixing or kneading have a synergistic effect in providing a refined clay product hav-ing significantly lower viscosity when dispersed or slur-ried.  The refined products produced in accordance with the method thus have particular use as paper coating pigments.                             -I-

Abstract: ABSTRACT OF THE DISCLOSURE           A load-responsive pressure reducing valve assembly for hydraulic brake systems to be interposed between a brake master cylinder and the rear wheel brake cylinders of a wheeled vehicle.  The valve assembly includes a fluid pressure proportioning valve which restricts the flow of fluid from the master cylinder to the brake slave cylinders during a predetermined range of increasing fluid pressure supplied therefrom to the brake slave cylinders.  The valve assembly also includes a deceleration sensing valve having a spherical inertia-responsive member that is responsive to a predetermined rate of vehicle deceleration to travel a predetermined distance up an incline to close off the supply of hydraulic fluid to a control chamber wherein the fluid pressure acts on a portion of the aforesaid proportioning valve, thus setting the reduction starting pressure of the fluid pressure proportioning valve.  A deceleration control is provided in the valve assembly and is responsive to a predetermined range of increasing hydraulic fluid pressure supplied from the vehicle brake master cylinder to steepen or increase the angle of inclination of the incline to optimize the front and rear wheel braking power distribution in correspondence with the load shift which occurs as a result of the vehicle braking operation under any given load condition on the vehicle.   1.

Abstract: FIRST IN - FIRST OUT MEMORY ARRAY CONTAINING SPECIAL BITS FOR REPLACEMENT ADDRESSING                   Abstract of the Disclosure A first in - first out auxiliary memory array for storing binary data wherein each member (word) of the array includes a special bit which is used in combination with the special bits of the other members comprising the same member set to form the address of the next member whose data is to be replaced.  Each member comprises an identifier field, a data field and the aforementioned special bit.  When a member set is addressed, each member of the set is read to determine whether there is a match on the respective ident-ifier field.  If there is a match, the data field of the same member is utilized.  If there is no match on the identifier field of any member of the addressed set, the main memory is accessed for the necessary replacement information which is to be written into the member which contains the oldest data.  The address of the last-named member is determined by the exclusive ORing of the special bits of all the members comprising the given set.  When the replacement data is written into the addressed member, the state of the special bit thereof is inverted.  The inverted state of the special bit is written into the member simul-taneously with the writing in of the replacement data.

Abstract: Système d'allumage électronique pour moteur multicylindre à combustion interne permettant de commander l'instant d'allumage du mélange air-carburant injecté dans les cylindres selon deux modes de fonctionnement: un mode statique et un mode dynamique gouvernés par la grandeur des paramètres physiques les plus représentatifs du régime de fonctionnement du moteur, en particulier la position de la course des pistons, la vitesse de rotation et la charge du moteur et, système permettant d'assurer le cycle d'allumage du moteur et d'éviter les régimes de survitesse de rotation du moteur; système comprenant, notamment, un transducteur de la position de la course des pistons, un bloc de contrôle de l'instant d'allumage dont les signaux de sortie sont appliqués à un bloc de distribution qui alimente séquentiellement et cycliquement des générateurs d'étincelles connectés aux bougies des cylindres.  Le transducteur de la position de la course des pistons élabore, au cours d'un cycle d'allumage du moteur, deux séquences identiques de signaux électriques, en forme de créneaux de durées inégales, le nombre des signaux de chaque séquence étant égal au nombre des cylindres:  une première séquence D1 décalée angulairement en avance d'une quantité ?M sensiblement égale à l'angle d'avance dynamique d'allumage, sur une seconde séquence D2.  Le front avant des signaux de la séquence D1 détermine l'angle d'avance maximal qui peut être contrôlé, et ces signaux sont appliqués au bloc de contrôle de l'instant d'allumage.  En outre, le front avant des signaux de la séquence D2 détermine l'angle d'avance statique, et les signaux des séquences D1 et D2 sont appliqués dans un détecteur de coincidence dont les signaux de sortie gouvernent le cycle d'allumage du moteur.  Les signaux des séquences D1 et D2 sont appliqués à des comparateurs de temps qui discriminent les régimes de vitesse de rotation du moteur, notamment le régime des basses vitesses inférieures à une valeur .omega.m et le régime des survitesses supérieures à une valeur .omega.M.degree.  Finalement, les signaux de sortie du détecteur de coincidence et les signaux de sortie du bloc de contrôle de l'instant d'allumage commandent le bloc de distribution.

The flow regulating member and the casing define a first chamber at one end of the flow regulating member.  A stem is rotatably mounted within the casing and is mechanically coupled t the flow regulating member to rotatably drive the flow regulating member within the casing.  The stem has an annular rim formed toward and positioned within the first chamber.  At least one annular seal surrounds the stem to effect the seal between the stem and the casing.  Valving and/or porting is provided for introducing a pressure equal to or greater than the line pressure into the first chamber whereby the pressure acts on the annular rim to move the stem in an axial direction to compress the annular seals.
