Abstract: hard candy confection is disclosed which offers an extended effervescent reaction and improved shelf stability, by the incorporation of separate reactive components achieving an in situ neutralization and effervescent reaction within the candy on its consumption. The respective ingestible reactive acid component and ingestible reactive base component are incorporated into separate portions of the candy base, and the resulting portions are thereafter positioned adjacent each other, and may be further incorporated one into the other. The ingestible reactive acid component may comprise citric acid and the ingestible reactive base component may comprise sodium bicarbonate. The separation of these reactive components in the resulting hard candy promotes a controlled release of the effervescent sensation with a corresponding improvement in shelf stability.

Abstract: A system and method of evaluating the radio coverage of a geographic area (105, 110 or 115) serviced by a digital cellular radiotelephone communication system is described which comprises a plurality of base stations (101, 106 and 111) each having a transmitter and a receiver and a plurality of mobile units (100) having co-located transmitters and receivers for transmitting and receiving communication message signals between the base stations (101, 106 and 111) and a mobile unit (100). During operation, the position of at least one of the mobile units (100) operating within the geographic area (105, 110 and 115) is located when a call is received by a base station (101, 106 or 111). The base station monitors the signal quality of the call and collects information relevant to the actual performance of the communication system. The mobile unit location and corresponding signal quality data are passed from the base station to an evaluation tool (117) housed within the central operation and maintenance unit (116). The evaluation tool (117) collects the data, performs all necessary analytic and arithmetic computations, and provides a user-friendly representation of the characteristics of the radio coverage. With this representation of the radio coverage characteristics, the system operator can quickly and efficiently diagnose coverage deficiencies and take the necessary corrective action. By continuously monitoring subscriber calls and updating the pictographic representations, the system operator can actually observe the effect of the adopted modifications in a pseudo real-time fashion.

Abstract: A method for producing concrete products provided with inlaid patterns includes a) preparing a mold provided with recessed patterns making use of an ultra-violet-ray setting resin, b) casting substrate material into the mold and solidifying the substrate material to produce a block on the mold; c) peeling off the mold from the block to provide recessed patterns on the surface of the block which was in contact with the recessed patterns on the surface of the mold; d) filling an ornamenting or coloring material which contains ultra-violet luminous material into the recessed patterns on the surface of the block and solidifying the ornamenting or coloring material; and then e) grinding the surface of the block to remove excess ornamenting or coloring material from the surface of the block to thereby produce a finished concrete product provided with inlaid patterns on the surface thereof. When the ultra-violet-rays are emitted to the ornamenting material, the surface of the blocks brilliantly and clealy luminates so that an aesthetic change can be achieved besides the change of the brightness and the chroma. Thus, the blocks can be effectively used as wall-forming blocks and the floor-forming blocks.

Abstract: The present invention concerns a catalyst for polymerization of olefins, said catalyst comprising an inorganic support material with catalytically active chromium and titanium compounds bound on its surface. The catalyst is prepared according to the invention by bringing the catalytically active metal compounds sequentially in vapour phase onto the support material surface in excess amounts in relation to the binding sites available on the support material surface. The support material temperature is maintained above the condensation temperature of the vapour, preferably above 160°C, and simultaneously sufficiently high so as to achieve the thermal activation energy necessary for the generation of bonds between the support material and the catalytically active material or its compound. To avoid desorption of the chemisorbed compounds, the temperature is kept below approx. 500°C. The activity of a catalyst in accordance with the invention even with very low contents of the catalytic metals is as high as the activity of a catalyst of multiply higher metal contents that has been prepared by the methods of the conventional technology.

Abstract: Circuitry (118) facilitates a burst read of data from a memory (122). Addresses for each memory location are received by the circuitry (118) from a processor (113). For each word of data read from the memory (122), the circuitry (118) uses either an actual address received from the processor (113) to access memory from the memory (122), or generates a predicted address. The circuitry (118) uses the actual address from the processor (113) for reading a first address of data of the burst read and for subsequent addresses of data which had incorrectly predicted addresses. For other addresses to be read in the performance of the burst read, the circuitry (118), rather than waiting for an actual address from the processor (113), generates a predicted address for the read transaction. Data is obtained from the predicted address. In the meantime, an actual address for the read transaction is received from the processor (113). The predicted address is compared with the actual address. When the predicted address is equal to the actual address, the data is forwarded to the processor (113). When the predicted address is not equal to the actual address, the data is discarded.
