Abstract: A method of producing pure and dense amorphous fused synthetic silica. Silica of desired purity is wet pelletized or agglomerated to form particles having an average particle size of between about 5 to 2500 microns. These particles are calcined to volatilize impurities and increase density to at least about 0.9 g/cm<3>. Calcined particles are classified by size or reduced in size if desired or needed by grinding in such a way that the purity of the product is maintained.

Abstract: A communication system for a bus-type local area network (10), comprising a master station (1), and a plurality of normal stations (2...N). The master station is provided with a memory table for storing a status of each of the normal stations, and a control unit for inquiring each of the normal stations if it wishes to join a logical ring or not, and revising contents of the memory table according to a result of the polling, and each of the master station and the normal stations is provided with the function of passing a token representing a transmission priority to one of the stations adjoining thereto in the logical ring. Since the management and construction of the logical ring is performed only by the master station according to a polling system whereas the normal stations carry out only the passing of the token, the structure of the more numerous normal stations can be simplified and the overall cost of the LAN system can be thereby reduced.

Abstract: A processing method is presented for treating sludges from municipal and waste materials. The ashes from such sludges, containing SiO2 as a primary constituent, are treated with additives to tailor the feed material composition. Thermal processing, including melting, rapid cooling and subsequent annealing, produces a crystallized glass microstructure in which needle-shaped crystals of anorthite and  beta -wollastnite are infiltrated with a vitreous material. Such crystallized glasses having superior mechanical and aesthetic properties are an attractive architectural material which can be utilized for interior finishing, exterior walls, flooring as well as for interior decorations.

Abstract: A device (1) for working the ground comprises a frame (2) and a plurality of discs (6). Each disc is rotatably mounted on a lying shaft (5) which is provided on the free end of a pivotable standing shaft (4). In order to prevent jamming of the discs (6) by earth thrown up by adjacent discs (6), each standing shaft (4) is placed on the concave side of its associated disc (6).

Abstract: A high opacity, defined kaolin clay product having a relatively narrow particle size distribution, low colloidal particle content and an average particle surface area of less than about 30 square meters per gram is prepared by defining an aqueous kaolin clay slurry via controlled centrifugation to remove a substantial portion of the colloidal particles therein. Prior to being subjected to centrifugation, the aqueous kaolin clay slurry is prepared so as to improve the defining process achieved via centrifugation by first subjecting the aqueous kaolin clay suspension to scrub grinding so as to break up agglomerates into individual kaolin clay particles without substantial delamination of the kaolin clay particles. Thence, the mechanically dispersed kaolin clay suspension is dispersed well by the addition of a chemical dispersant, most advantageously sodium hexamethaphosphate, and dilution water is admixed into the aqueous kaolin clay suspension to reduce the solids content thereof to a level less than at least about 18% solids by weight, and preferably to about 5% to about 15% by weight, prior to centrifugation.

Abstract: A reiterative method for obtaining the glycosyltransferases useful for glycosyltransferase-catalyzed synthesis of a saccharide composition by serially bonding preselected saccharide units onto an immobilized acceptor moiety which is one member selected from the group consisting of proteins, glycoproteins, lipids, glycolipids and carbohydrates. The method comprises in a first iteration, the steps of (i) contacting an acceptor moiety immobilized onto a solid or semi-solid support with a mixture containing at least one glycosyltransferase under conditions effective to allow said glycosyltransferase to bind to the immobilized acceptor moiety thereby resulting in an immobilized acceptor moiety-glycosyltransferase complex, followed by (ii) contacting the immobilized acceptor moiety-glycosyltransferase complex with a preselected saccharide under conditions and in the presence of co-reagents sufficient to effect bonding of the preselected saccharide unit onto the immobilized acceptor moiety catalyzed by the glycosyltransferase thereby freeing the glycosyltransferase from the complex and obtaining an immobilized product. This is followed by a single or a plurality of subsequent iterations of steps (i) and (ii), such that the immobilized product obtained in step (ii) of a given iteration is used as the immobilized acceptor moiety in step (i) of the following iteration.

Abstract: The pressure control system includes a detector (16) sensitive to variations in the external pressure around a vehicle. Conduits for the entry of air (2) and the exhaust of air (4) includes shutters (6,7) to control the flow of air in or out of the vehicle. A control unit (14) closes the shutters to reduce the rate at which the pressure changes within the vehicle, until the pressure difference falls to a certain level. The pressure inside and outside the vehicle is thus balanced, after a suitable control period. A diversion channel (17) maintains the variation of internal pressure below a set level, by circulation of air flow between the interior and exterior of vehicle, to balance internal and external pressure.

Abstract: Higher harmonic control (hereinafter HHC) of helicopter rotor blade vibrations is provided by an actively controlled, rotatable, slotted cylinder (11) which is mounted at an outboard section of each blade (12). Continuous rotation of each cylinder (11) about its longitudinal axis produces a periodic aerodynamic force on the blade (12) at a frequency of twice the rotational frequency of the cylinder. The amplitude of force is controlled by the size of a slot opening (110,111,112,133) in the cylinder while the rotational speed of the cylinder is synchronized to run at a multiple of the speed of a rotor blade drive shaft. The amplitude and phase of the HHC force is regulated, either manually or by active feedback control, to minimize any vibratory load transmitted to the airframe through the rotor blade drive shaft. A significant advantage offered by this concept, relative to other HHC methods, is its low power requirement.   <IMAGE>

Abstract: An associative memory is utilized to perform LZW data compression. The respective locations of the memory contain a prefix code field and a character field. A register containing a code field and a character field is associatively compared to the locations of the memory to determine if a match exists therewith. If a match is found, the address of the match is inserted in the code field of the register and the next input character is inserted in the character field thereof. This process is continued until no match occurs. The code existing in the code field of the register is transmitted as the compressed code of the string and the contents of the register is written into the next empty location of the memory. A next cycle is initiated by nulling the code field of the register and repeating the described steps.
