Title: The controlled precipitation and use of amorphous silicia from geothermal fluid or aqueous media having a silicic acid concentration
Inventor: HARPER ROSS THOMAS
IPC: C01B33/12
Filed: 1990-03-21
Abstract: A method of obtaining precipitated amorphous silicas with substantially a tertiary aggregate structure (whether as an aqueous slurry, as cake, gel or otherwise) useful for coating and/or incorporation in paper and other substrates (e.g. rubber, plastics and the like) from a geothermal fluid (naturally or artificially generated - natural, including water infusion into geothermal systems) having sufficient silicic acid concentration, said method comprising:
     A. ageing the fluid to effect polymerization, thus establishing a silica sol, ageing meaning a process in which the source fluid after being made supersaturated with respect to amorphous silica is held for a period of time,   B. optionally (prior to, with and/or after step A - preferably prior to in order to reduce arsenic adsorption) reducing the temperature of the geothermal fluid and/or sol as the case may be,   C. inducing precipitation of amorphous silica from the sol under conditions that will provide the tertiary aggregate structure, and   D. thereafter harvesting the amorphous silica thus precipitated.

Abstract: To determine the phase and amplitude response of a superheterodyne instrument (10), a fixed frequency signal is applied to the instrument's signal input port (12). The superheterodyne local oscillator (20) is then swept to translate the fixed frequency input signal into a sweeping sinusoid that traverses the I.F. passband. Data is acquired as the signal sweeps the passband and is analyzed to determine the phase and amplitude characteristics of the instrument. These characteristics are logged in a memory and are used to remove instrument-induced frequency response errors from subsequent measurements.

Abstract: Described are new strains of  Drechslera spp. , which possess herbicidal effects against all varieties of barnyard grass, i.e.,  Echinochloa spp.  as weed but do not give any influence to crops under cultivation such as rice. Weed control agents according to the present invention, which contain one or more of the novel strains, have high safety and selectivity, thereby providing practical control effects against barnyard grass. Weed control compositions according to the present invention, which contain one or more of the new strains in combination with one or more chemical herbicides, have sufficient herbicidal effects even at dosages which are too low to permit control of weeds when they are applied singly, thereby making it possible to reduce the dosage of herbicides. The weed control compositions can therefore contribute to the prevention of environmental pollution and the occurrence of weeds with acquired pesticide resistance.

Abstract: Described herein are method and apparatus for producing instantly cookable pasta including various kinds of pasta and Chinese and Japanese noodles, and an encased instantly cookable pasta produced by such method and apparatus. According to the invention, part of raw dough of a starting mixture, which contains wheat flour as a major component, is subjected to preliminary steam-cooking, and then mixed with the remaining uncooked part of the starting mixture. The resulting mixture is then processed through shaping (14), steam-cooking (38, 50) and drying stages to obtain instantly cookable pasta, enshrouding the instantly cookable pasta product in a water-permeable casing before shipment. Due to suppression of thermal degeneration of gluten, the instantly cookable pasta possesses favorable resiliency and is free of the smell inherent to raw wheat flour and cohesion of individual pasta cords. In order to restore the cooked edible state, the encased pasta can be put in hot water together with the casing, permitting hot water to impregnate uniformly into the pasta. The water-permeable casing facilitates the handling of the pasta in cooking and improves its restorative quality to obtain cooked pasta of palatable touch and flavor.

Abstract: An analog-to-digital conversion module and method minimize software involvement by providing a programmable control table (62, FIG. 2) comprising a plurality of conversion command words (CCW's). Each CCW (FIG. 7) designates conversion parameters such as channel and reference selection, input sample time, and re-sample inhibit for one conversion operation, upon conclusion of which a digital value is stored in a corresponding result table. A set of CCW's defines one or more conversion sequences. Upon conclusion of each sequence, an interrupt can be issued and the result table may be read by an associated device, such as a CPU. If desired, the CCW sequence may be dynamically altered during operation of the conversion system.

Abstract: The invention relates to a switching unit for an asynchronous time-division multiplexing transmission system which transmits cells arriving on feeding lines to a serving line by means of temporary storage of the cells in buffers and an evaluation in a comparator of the route identifier contained in the cells. The cells are transformed in a re-arrangement circuit (25) into intermediate blocks in such a way that the route identifier of the cells which are supplied to the feeding lines (7a to 7d) is contained in at least one intermediate block. Once the allocation of the route identifier to a serving line (17) has been established in the comparator (16) coupled with at least one intermediate line (14a to d), the cell data contained in the different intermediate blocks are read into the buffers (22a to d) allocated to each intermediate line. A multiplexer (24) then connects the outputs of the buffers to the serving line for read-out of a cell.

Abstract: An information processing apparatus (1) has a coordinate data inputting means (31, 32) for sequentially inputting coordinate data by operation of a movable member (6), the coordinate data corresponding to the position of the movable member (6). The movable member is a pen (6), a change of the moving angle of its locus being detected by a detecting means (24) as an angle between the position of the pen (6) and a predetermined base position based on the coordinate data. The base position is displayed on a display (5) as a circular image in the form of a dial on which the pen (6) may be penned down so that a processing means detects the rotating angle of the pen (6) to change a function to be processed. In one arrangement, the circular image acts as a jog control, rotation of the pen (6) causing turning of page numbers.
