Abstract: The invention relates to a process for producing a refractory material and to the material so-produced. The process comprises calcining red mud obtained as a by-product of the Bayer process of producing alumina, grinding the calcined product to form particles of -4 Tyler mesh, mixing the ground product with a binder (e.g. colloidal silica, colloidal alumina, sodium silicate or sodium aluminate) and sufficient water to produce a formable mixture. The mixture is then formed into a desired shape and fired, preferably after curing and drying. The resulting fired products have good resistance to high temperatures and to corrosive chemicals such as cryolite. Consequently, the products can be used as refractory linings for aluminium production cells, and in similar applications.

Abstract: During non-shift modes of transmission operation, the line pressure is controlled according to a basic line pressure control schedule (14). Upon a shift being initiated it is determined if the shift is being conducted under power ON or power OFF conditions by sensing the status of a idle switch associated with the engine throttle valve. In the case of a power ON shift, first and second maps which are record solenoid valve duty cycle in terms of engine load and vehicle speed are read out of memory and sequentially used one after the other to control the line pressure during the shifting. In the case of a power OFF shift, tables recorded in terms of duty cycle and vehicle speed are fetched and used one after the other. The changing from the first map or table to the second one is determined by comparing the rotational speed ratio which exists between the input and output shafts (12, 13) of the transmission with a shift solenoid control schedule (14) which relates to the type of shift and which is being conducted and which is recorded in terms of gear ratio and engine load (e.g. throttle opening).

Abstract: Device and method for venous-flow stimulation, through localized periodic application of squeezing forces, essentially limited to the phalanx of the digits and thumb, and to the adjacent region of the palm of the hand. To this end, an inflatable mitt is applied to the said phalanx and adjacent regions, with digits and thumb projecting beyond the mitt. The mitt may be wrapped with suitable fabric, such as surgical gauze or muslin, to provide a circum­ferential tie of the inflatable regions, the tie providing hoop-tension reference for inward applica­tion of a squeezing pressure/release cycle; and the squeeze is applied in unison circumferentially around each of the individual digits (and thumb) at the phalanx region. Alternatively, the inflatable mitt may be embedded in an orthopedic cast, without impairing the application of pulsed pressure local to the indicated region in this case the circumferen­tial tie is provided by the case. In either case, arterial throughput is also noted, concurrent with such venous-flow stimulation, and the arterial through­put is enhanced when the stimulating pulse is sustained for a brief period prior to a relaxation dwell between pulses.

Abstract: There are provided digital communicating method and apparatus for modulating digital signals into chirp signals and performing the communication. In this method, pulses indicative of digital signals of codes "1" and "0" are modulated, the modulated pulse signals are converted into chirp signals, the chirp signals are converted into the optical signals and output as trans­mission signals, and the digital signals are input and the pulses based thereon are generated. A wave of a predetermined frequency is multiplied to the pulses indicative of "1" and "0" of the digital signals and the modulation is executed. The communication signals can be converted into the chirp signals by the chirp conversion elements using the surface acoustic wave-­dispersive delay lines having different converting characteristics by the simple construction. On the reception side, the modulated signals are demodulated by the chirp conversion elements having characteristics opposite to those of the chirp conversion elements on the transmission side. Thus, the code signals of "1" and "0" can be accurately discriminated and the error rate can be reduced. The communication reliability is improved.
