Abstract: In a mobile communication system having two operating systems co-existing in one area, and a mobile station having a transmitting and receiving circuit and a control unit subscribing to one of the two mobile communication systems for selecting a control channel thereof, a normal scan of the control channel of the subscribed-to system is activated, and then an extra scan of the control channel is activated when the control channel is not available during the normal scan, thereby reducing the possibility of an involuntary use of a non-subscribed-to system when the mobile station is temporarily in a blind section of the subscribed-to system for a while.

Abstract: On connection (6), a redaction computer (5) puts the signals into a modulator-adapter (7) suitable for the input into a transmission mo­dulator (8). The signal amplified by an amplifier (9) is transmitt­ed into the ether and captured by antennae (11) of users. From the­se antennae (11), a receiver (12) picks and gives it up to a modula­tor-adaptor (13) which makes it compatible with a micro-processor (14) acting as as data access-key in order to allow the signal dif­ferentiation in only one emission. If the decodified message arriv­ed form the modulator-adapter (13) has correspondence of codifica­tion with the micro-processor (14), a device (15) is activated which consists of a printing device or of a magnetic memorizer for compu­ters, if it is about either a text to transmit or a transducer for the control of electrical machinery. Furthermore, to accede to the radaction computer, the user will digitate the reference codes for services and news which can be deduced from tabulates transmitted by the editor. By means of orders, the programme of each periphe­ral computer will automatically send the necessary data on a line which allows the system to turn out interactive.

Abstract: The present invention relates to methods for selectively reducing NO x  so that nitrogen can be removed from emission effluent streams and NO x  emissions can be reduced to very low levels. In addition, the present invention teaches a method whereby NO x  and SO x  may be simultaneously removed from the effluent stream. 
     The present invention teaches the reduction of NO x  with -NH and -CN containing selective reducing agents such as ammonium sulfate, urea, NH₃, and cyanuric acid. Initially, the selective reducing agent is decomposed in a fuel-rich environment to form highly reactive decomposition products. The reaction of the selective reducing agent to produce its decomposition products, such as NH, NH₂, isocyanic acid, and related reaction intermediates, takes place in an oxygen-free, fuel-rich decomposition zone with the reaction temperature in the range of from about 300°F (150°C) to about 3000°F (1650°C). 
     After the selective reducing agent is decomposed in the absence of oxygen, the decomposition products are contacted with the effluent stream containing NO x . At this point the oxygen level of the stream must be carefully controlled to provide an excess of oxygen so that the selective reduction of the NO x  species will occur. It may be necessary at this point to inject air into the effluent stream in order to maintain the proper oxygen-rich (fuel-lean) conditions for NO x  reduction. In this   second "reaction zone," NO x  reduction takes place at temperatures of from approximately 500°F (260°C) to approximately 2600°F (1425°C). 
     The present invention can also be used in conjunction with SO x  control technology. Specifically, species used to control SO x , such as limestone, dolomite, quicklime, and hydrated lime, can be added in conjunction with the selective reducing agent for simultaneous NO x  and SO x  control.

Abstract: Data characters to be transferred from a peripheral device to a central processing unit are serially shifted into the receiver shift register of a universal asynchronous receiver/transmitter (UART). A multiple byte first-in-first-out memory stores a plurality of data characters received by the shift register. The UART checks the status of each data character stored in the FIFO to determine whether it will trigger an exception. A bytes till exception register indicates the number of data characters remaining in the FIFO until an exception is encountered. Then, upon request by the CPU, the UART provides the count of consecutive valid data characters from the top of the FIFO to the first exception, eliminating the need to check status on every transferred byte. Each of the multiple channels of the UART includes an Initialization Register. Setting the appropriate bit Initialization Register of any UART channel allows concurrent writes to the same selected register in each channel's register set. This function reduces initialization time for all of the common parameters that are loaded into each channel's registers. The UART implements a methodology which allows for the processing of any control characters or errors received by the UART during DMA while internal and/or external FIFOs are being used.

Abstract: An acceleration sensor (10) comprises a tube (14) formed of an electrically-conductive non-magnetic material; a stop (30) defining an end of the tube which moves longitudinally thereof in response to temperature; a magnetically-permeable element, such as a iron washer (44), proximate with the end of the tube (14); and a sensing mass (46) in the tube (14) comprising a pair of permanent magnets (48) secured to the opposite sides of an iron spacer (50) so as to place a pair of like magnetic poles thereof in opposition. In operation, the sensing mass (46) interacts with the iron washer (44) so as to be magnetically biased against the stop (30), while the stop (30) moves longitudinally of the tube (14) to maintain a nearly constant threshold magnetic bias on the sensing mass (46) irrespective of variations in sensor temperature. The sensing mass (46) is displaced in response to acceleration of the housing (12) from its first position against the stop (30) towards a second position in the tube (14) when such acceleration overcomes the magnetic bias, while the tube (14) itself interacts with the sensing mass to provide magnetic damping therefor. Upon reaching the second position in the tube 14 , the sensing mass (46) bridges a pair of electrical contacts (54) with an electrically-conductive surface (56) thereof to indicate that a threshold level of acceleration has been achieved. An electrical coil (60) is secured proximate with the iron washer (44) which, when energized, reversibly magnetizes the latter, whereby the sensing mass (46) is either repelled to the second position in the tube or more strongly biased against the stop (30).
